In what fictional work does the planet Cybertron feature?

Cybertron is a fictional planet, the homeworld of the Transformers in the various fictional incarnations of the metaseries and toyline by Hasbro. In the Japanese series, the planet is referred to as "Cybertron" (first shown on Japanese "Galaxy Force" packaging, despite the fact that "Cybertron" is the Japanese name for "Autobot") pronounced as セイバートロン "Seibātoron". Cybertron is populated by mechanical life forms of variable size who can transform into all kinds of machinery. These are called Cybertronians, or Transformers.

List of Transformers planets

This is a list of planets appearing in the fictional "Transformers" universe.

Akalo (also known as Archa Nine) is the 9th planet in the Arca System. It is an organic forest planet that is populated by the Akalouthians (a technological primitive people).

Andellor is a library planet for a highly evolved society.

Antilla is an ancient ringed planet which was the site of an early Autobot colonization effort. This colony was wiped out by the deadly plague known as Cosmic Rust as seen in "The Transformers" episode "Cosmic Rust."

Antilla is also home to adorable creatures known as Antillan Bumble-Puppies.

Arkus is a planet that is a home to robotic creatures that first appeared in the 3H Comics.

Aquatron was a planet introduced in the novel "" notable for being almost entirely covered in water. It was part of the Quintesson Empire and its inhabitants were enslaved as part of the illusion of the Quintesson "Co-Prosperity Sphere." Aquatron was a Cybertronian colony, and its native inhabitants-the Aquatronians and the Sharkticons-are of Cybertronian descent. The Autobots and Decepticons arrive here and quickly learn that the planet is under Quintesson control, after one of the planet's artificial rings-used to gather and fire energy-disables both their ships. A massive battle then ensues between the Cybertronians and the Sharkticons, with the Sharkticons later abandoning the Quintessons in temporary favor of Megatron. However, the awakening of a massive Quintesson jellyfish known as the Hydratron-which while dormant had served as a continent/city for the inhabitants of the planet-proved devastating, and the Autobots and the Decepticons eventually left the planet behind. One benefit of their visit was that Aquatron was freed from Quintesson rule and fell to the jurisdiction of a massive race of underwater Transformers, including one known as Leviacon. The planet was also inhabited by the Pirahnacons, a deadly race that fed upon Transformers.

Known inhabitants of Aquatron include:Athenia is a planet where the first Galactic Olympics take place in 2005. In 2011, it became another base of operations for the Autobots.

Beast (also known as Beest) is a distant planet that is inhabited by a race of anthropomorphic animals called Beastformers. There were few dissenters on this planet until the Decepticons arrived. Following this, the inhabitants have each sided with the Autobots or the Decepticons.

Centaris Seven is a planet that contains plants that can secrete a corrosive that is deadly to Cybertronians.

Ceti Alpha Seven is a planet that is filled with murky jungles and swamps.

NOTE: The planet may have been named in reference to the planets Ceti Alpha Five and Ceti Alpha Six of the "Star Trek" series, both being most well known for their story role in the film "."

Chaar (in Japan, Jarr) appeared in "The Transformers" television series, debuting in The Five Faces of Darkness (Part 1) in season three. It is a small, burned-out husk of a planet in distant space, easily mistaken for a smudge on a map. It apparently supported a civilization at one point, as abandoned structures are seen on the surface. The surface is desolate and lacks vegetation, but some native lifeforms still exist, including an enormous spider.

Following Unicron’s attack on Cybertron in 2005, the Autobots reclaimed Cybertron, and the surviving Decepticons (who were without their leader Galvatron at the time) were forced to withdraw to Chaar, where they struggled to eke out an existence, relying on the meager amounts of Energon that could be acquired from other worlds. Eventually, Cyclonus set out to find Galvatron but, in his absence, the Quintessons supplied the Decepticons with Energon in return for their assistance in launching an attack against the Autobots. With the return of Galvatron, the alliance was restructured, but the ensuing attack on Cybertron ended in failure, resulting in the Decepticons again returning to Chaar, which served as their base of operations for the remainder of the series.

After Earth and Cybertron, Chaar appeared in more episodes of the original television series than any other planet.

Chaar was also mentioned in "", but as an asteroid belt, not a planet.

In "Transformers Animated", Strika leads "Team Chaar" which consists of Spittor, Cyclonus, Oil Slick, and Blackout.

Cheyne is an arid desert world whose culture is similar to the Wild West of the late 19th century United States.

In "", Circuit Planet was the name of a world created by Alpha Q using the power of his Energon sun. It is covered in roads and highways.

Circuit Planet was later destroyed by Megatron who was controlling Unicron's body.

Combatron is a planet that was established as colony world that by King Atlas until a war erupted that left it all but devoid of life.

Cybertron is a fictional planet, the homeworld of the Transformers in the various fictional incarnations of the metaseries and toyline by Hasbro. In the Japanese series, the planet is referred to as "Cybertron" (first shown on Japanese "Galaxy Force" packaging, despite the fact that "Cybertron" is the Japanese name for "Autobot") pronounced as セイバートロン "Seibātoron". Cybertron is populated by mechanical life forms of variable size who can transform into all kinds of machinery. These are called Cybertronians, or Transformers.

Daffodil II is a luxurious all-natural planet.

Darhos is a planet that was a veritable paradise. As time went on, certain groups began to monopolies control of the resources and money, leading to vast class split. Now Darhos’ decadent ruling class lives in the lap of luxury, eating, drinking and enjoying the pleasures of the flesh amidst architecture and fashion that seems a mad blend of many of Earth’s ancient cultures while the poverty-stricken citizens live in slums. Should the disenfranchised attempt to rise up against their self-proclaimed masters, they would be captured and thrown into labor camps in the barren northern hemisphere.

Delta Pavonis IV is a planet where the inhabitants are anthropomorphic cats and anthropomorphic dogs. It was featured in "The Transformers" episode "The Big Broadcast of 2006."

Deneb IV is a planet where Kup nearly lost all of his platoon when the Decepticons used a surprise acid shower on them. It was mentioned in the comic book issue called "The Desert Island of Space."

Dread is a rather unpleasant planet that is the home of the monster Chaos. It was featured in "The Transformers" episode "Chaos."

This is a version of the real-world planet Earth where humans have made contact with Transformers. Earth is the third planet from the Sun in the Solar System in the Milky Way galaxy. It is a world populated by a wide variety of native organic lifeforms, most notably, humans. Versions of this planet are known to exist in many dimensions within the multiverse, and it frequently becomes involved in the conflicts of the Transformers. Perhaps too frequently. Whenever something (or someone) leaves, escapes, or is otherwise ejected from Cybertron, there's a disproportionate chance it will eventually wind up on Earth.

In some universes, Earth becomes the post-apocalyptic planet Gaea. In other universes, Earth is the planet that formed around Unicron as seen in "".

Edaps is a planet that supports mechanized life.

Eurythma is a planet whose culture is based solely on music. Among their achievements is a three-part harmony of incredible destructive power.

Femax is a planet in the Marvel Comics series where feminism has been taken to the extreme: women rule all aspects of the planet and men are only used for labor.

Floron 3 is a planet which is best known as a place to purchase large cans of Robot Insecticide.

Gaea (ガイア "Gaia"), or Gaia, is post-apocalyptic Earth in the distant future, tens of thousands of years away. Thanks to the millennia without humanity, most of mankind's structures have been completely destroyed and most of the planet has been grown-over with dense jungle.

Ganzvort is a planet. All that is known about it is that it has a region called New Jersey.

Ghennix is a planet. It was featured in Marvel Comics where it was devoured by Unicron.

Gigantion, or Giant Planet, is a fictional planet home to giant Transformers in the animated television program "". It is referred to as Gigalonia in "Transformers: Galaxy Force", the Japanese version of the show. Much like how Velocitron is referred to as both "Velocitron" and "Speed Planet", Gigantion has a similar dual name. Its actual name was revealed in the episode "Balance".

Gigantion is home to one of the four Cyber Planet Keys and is one of the four ancient Transformer colonies. The titanic Transformers of Gigantion are large and powerful where their size are compared the combined forms of the known Combiners on both the Autobots' side and the Decepticons' side. The Gigantion Transformers are fortunately not much given to violence and warfare. Most are gentle and peaceful, desiring only to hone their skills and build ever grander structures. They work closely with the small Mini-Con Transformers, who can tackle the delicate tasks too refined for the heavy manipulators of their bulk comrades.

Once part of a star system within the Milky Way galaxy, the planet fell into a spatial rift and was transported to a distant universe. The only Transformers to escape this fate were a quartet of Mini-Cons consisting of Jolt, Six-Speed, Reverb, and Safeguard. Vector Prime eventually discovered and saved them, and they became the Mini-Con Recon Team. Each Transformer on Giant Planet has a Mini-Con partner. The larger Transformers all become construction vehicles with the Mini-Cons integrated into both modes. Gigantion's de facto leader is Metroplex. The Transformers from this world have accents that sound Scottish or Irish.

The Giant Transformers have a habit of building giant cities and abandoning them, with older cities (the oldest of which are buried deep within the planet's crust) forbidden by planetary law by erasing their data so no one could come back. The planet was once the target of an attack from the mysterious Planet X, its inhabitants having eradicated most every other civilization in their universe and seeking to subjugate Gigantion's populace as their next conquest. Gigantion's people, however, retaliated, with its inhabitants modifying themselves including their planet with help from the Cyber Planet Key into becoming large enough to combat the invasion.

This eventually led Planet X's inhabitants to use their planet-busting weapon in a last-ditch effort to win the war, but the weapon overloaded and destroyed Planet X. Horrified and saddened by their part in the extinction of an entire race, Gigantion's inhabitants remodeled themselves into construction vehicles and took up their custom of building and then abandoning cities, perhaps as a form of self-punishment, focusing their energies solely on creation, not destruction. The Giant Transformers built cities underground and used holographic images of the sky on the top to make things nice. They started at the very center where they left the greenery. They have many mottoes like "Safety First" and "Always look forward, never back". Gigantion is mentioned in the first chapter of "".

Known inhabitants of Gigantion include:Goo is the name of many garbage planets in the original Transformers television series, debuting in the season 3 miniseries "The Five Faces of Darkness". Goo is filled with garbage and belongs to the Junkions, and takes its name from a powerful adhesive that clings to anything unless disabled. After the Quintessons blew up Quintessa in an attempt to destroy the Autobots, the Autobots were set adrift in space until they landed on Goo. The Autobots were attacked by a giant garbage truck that killed Springer before Rodimus Prime could disable it. Later the Quintessons found out that the Autobots were alive on Goo. They made an alliance with the Decepticons, who were without their leader, Galvatron, and attacked the Autobots on Goo. When Galvatron returned, he was furious that the Decepticons had abandoned him. He attacked the Decepticons and Quintessons with an army of Sweeps, before being placated by Quintesson manipulation. As the Autobots fled, Galvatron destroyed the planet of Goo. Later, the Junkions were able to repair and resuscitate Springer. Another Goo planet was featured in the episode "Chaos," where the Autobots discovered that the Decepticons had come into possession of crystals produced by the monstrous Chaos that could pierce any metal.

Gorlam Prime is a planet that is in the same sector of space as the Benzuli Expanse cosmic anomaly. Originally inhabited by organic beings, they progressively undergo mechanization until they achieve full mechanical status.

Greengard is a paradise planet where its plants never turn brown and its flowers never wither.

Hive is a planet where its inhabitants are insectoids that live beneath the surface of the planet.

Hub is a powerful planet-spanning network of cyberformed structures. It housed the Decepticon progenitor known as the Liege Maximo. Hub was the seat of power for the Cybertronian Empire.

Hydrax Plateau is a planet where a younger Ratchet was dispatched to when looking for survivors of a chemical attack caused by Oil Slick. It was featured in the comic tie-ins to "Transformers Animated".

The name has subsequently been assigned to a region of Cybertron in the "" continuity.

Hydrus Four is the only planet on which the miracle restorative Nucleon can be found. It was mentioned in "" episode "A New Hero," in which Blurr instructs E.R.V.I.S. to take the Sigma there.

Hyperion is a planet that is home to the mercenary Krakon.

In "", Iron Planet was the name of a world created by Alpha Q using the power of his Energon sun. It is metallic in nature and was filled with a lot of Energon. It was destroyed when the Terrorcons deprived it of its Energon.

Jhi is a green planet that is home to an ancient race of people with dog-like faces and elf-like ears. It was featured in Marvel Comics.

There had been different versions of Jungle Planet in the Transformers franchise:

In "", Jungle Planet was the name of a world created by Alpha Q using the power of his Energon sun. It was a lush, jungle-like paradise.

Jungle Planet (also called the Beast Planet on occasion) is a fictional planet home to Beast Transformers in the animated television program "". It is referred to as Animatros in the Japanese version of the series "".

The ship that transported the Cyber Planet Key to this world was called Hyperborea. Home of one of four Cyber Planet Keys (which exists in the form of a statue called the Beast Totem) and ancient Transformer colonies sent to reacquire them. The Beast Totem is in a temple where there are different wall carvings of Earth's animal life. All of Jungle Planet's inhabitants have animal alternate forms. Jungle Planet is a lush, green planet that contains dangerous volcanic activity, dangerous seismic activity, lightning storms, and monstrous sentient plant. The Jungle Planet Transformers took animal alternate modes.

For a time, the Jungle Planet Transformers were leaderless leaving their world torn by violence and poverty. Many were taken under the tutelage under Zen-master Backstop in the way of non-violence and self-defense. Eventually, Scourge, a student of Backstop, grew impatient with his people's suffering and forced a rebellion against those taking advantage of the chaos, strong-arming his way into leadership position in a series of battles to determine who would be strong enough to become leader. Corrupted by his new-found power and position, Scourge forced a "peace through tyranny" campaign, bringing his people the peace and prosperity he promised them, but only through a dictatorship ruled by the credo of "might makes right." However, Scourge couldn't totally rid himself of his old master's teachings and he enforced a strict series of laws regulating disputes being settled only through formal duels of strength with sabotage and especially unjustified death of a defeated foe as the planet's highest offense.

Overhaul was sent to acquire the Cyber Planet Key here while being told not to interact with its inhabitants. This ended up being the opposite when Overhaul was rescued from a seismic activity by Backstop. While protecting Snarl from Scourge and Megatron, Overhaul was transformed into Leobreaker as a result of a combination of tapping into the power of Jungle Planet's Cyber Planet Key and scanning a wall-carving of a lion. Eventually, Leobreaker, Backstop, and Snarl convinced Optimus Prime to rethink his credo of non-interaction with local customs in order to acquire the Key.

The "Hyperborea" ship would later carry the people of Jungle Planet to safety (along with another ship, Ogygia), after the planet was consumed by the Black Hole. However, when the Black Hole was destroyed, the planet was restored. When the Autobots attempted to use a gigantic rocket to move the Jungle Planet back into its orbit, Galvatron attacked and damaged the rocket. The Jungle Planet threatened to crash into Cybertron. The combined strength of Scourge, the Autobots, the former Decepticons (Dark Crumplezone, Ransack, Thunderblast, and Thundercracker), and their allies from the various planets were able to combine their strength and move the rocket back into place.

Known inhabitants of Jungle Planet include:Also on Jungle Planet are generic Transformers that each resemble a different animal such as a Brontosaurus, an owl, a lobster, a deer, a giraffe, and a tropical bird.

Junkion, also known as the Planet of Junk is the home planet of the Junkions, a group of Transformers who transform into motorcycles. The planet and the Junkions first appeared in "". It is not really a planet in the normal sense of the word, but rather, a landfill in space that has accumulated enough mass to be held together by gravity. Depending on the storyline, it has been depicted as either a traditional spherical planet or as an elongated slab. In the original movie art and storyboards, the Planet of Junk was intended to be a spherical planet, with several rounded slabs seeming to rise off of its surface. In the end, only the "northernmost" rounded section of the planetoid was retained on film. In the third volume of the Devil's due comics the android Serpentor downloaded information on the history of Cybertron from Soundwave. Mentioned among that information was the Quintessons, Alpha Trion, Megatron and Soundwave, the planet of Junk, a warrior named Optimus Primal and the Autobot Matrix of Leadership. In "", the Autobots aboard the Ark come upon the planet Junkion where they meet Wreck-Gar and the other Junkions. It is later discovered that Junkion is made up of the wreckage of various ships drawn together by the gravity of the Requiem Blaster, and subsequently ripped apart when the blaster is stolen by the Decepticons.

Known inhabitants of Junkion are:Jörmungandr is a serpent-shaped planet. It was featured in the "Beast Wars Neo" manga where it was Cohrada's homeworld.

Kaiba-5 is a planet that was referenced in "".

Klo appeared in the Marvel Comics "Transformers" comic book series, and is notable for being the location of the final battle of both the U.S. and UK versions of the series. Klo was introduced in issue #80 in the U.S. version, and #331 in the UK version. Klo is a beautiful, peaceful planet, rich in natural resources and inhabited by benign, harmless creatures called Klozians. The planet was invaded by Decepticons under Bludgeon's leadership, after the Transformers had won the war against Unicron. Following Unicron's death, Cybertron seemed to be in danger of being destroyed, so the Decepticons fled the planet in search of new worlds to conquer. They selected Klo, where they started mercilessly slaughtering the native Klozians. The Autobots tracked the Decepticons to Klo and attempted to rescue the Klozians, but weak leadership from Grimlock led to heavy casualties by the Autobots and their forces were nearly wiped out. Finally, a newly resurrected Optimus Prime and the Last Autobot arrived on Klo, and while Optimus Prime fought against Bludgeon, the Last Autobot resurrected the dead Autobots. Facing invincible opposition, Bludgeon and his Decepticons retreated back into space and Optimus Prime and his Autobots stayed to help the Klozians rebuild their planet.

Lanarq is a robotic planet who waged a centuries-long war with Xetaxxis.

Lithone was a planet populated by intelligent Transformer-like machine life. It was destroyed by Unicron in the Earth year 2005. The last known survivor of the planet, Kranix, was sentenced to death and executed by the Quintessons after being found "innocent" of an unspecified crime (It is rumored that the Quintessons often judge lifeforms with the crime of "stealing" Cybertron from them 12 million years prior, as seen in the Five Faces of Darkness miniseries, but Kranix was from Lithone, so the "jury reach a verdict" of innocent—yet Kup and Hot Rod, of Cybertron, were found innocent in the film as well).

In the script and in the Marvel Comics "" adaptation, the Lithonians could transform into spaceships. Lithone has also been referenced as "Glithos" or "Glinthos" due to the unclear articulation of its last surviving native, Kranix, before his execution.

Nebulos, sometimes known as Nebulon, is a planet in the fictional Transformers universes.

Nebulos is a somewhat Earth-like planet far away from both Earth and Cybertron, and is the home to a humanoid race known as the Nebulans. The planet and its inhabitants were first introduced as the back story for Hasbro's new Headmaster and Targetmaster toys, later expanded by the Powermaster toys. These toys are robots that transform into vehicles or animals, and include Nebulan sidekicks that transform into the robot's head, into a weapon, or into the vehicle's engine. The toys themselves never expanded on Nebulon or its inhabitants, but both the TV series (in its fourth and final season) and the Marvel Comics comic book did, with drastically different, mutually inconsistent versions. In the TV series, the Nebulons were shown to be green-skinned. The planet Nebulos does not exist in the Japanese continuation of the franchise. Thus, with no Nebulos and no Nebulons, a different origin was given for the Headmaster and Targetmaster Transformers.

In the Marvel comic book, Fortress Maximus had grown weary of the civil war on Cybertron, and led a group of Autobots in search of a new planet where they could live in peace. They settled on Nebulos, but the Decepticons followed them. The comic book version of Nebulos is an idyllic, peaceful world where war has long since been discontinued and all weapons have been locked away. It is governed by a council of peers. The arrival of the Transformers scared the Nebulans, and they were forced to hold an emergency council meeting to deal with these strange new creatures. The Autobots wanted to live in peace with the Nebulans, but the Decepticons wanted to conquer them and kill the Autobots, so the Autobot-Decepticon civil war restarted on Nebulon. Both sides allied themselves with Nebulans, the Autobots generally with common people who had become familiar with them and did not see them as a threat, and the Decepticons generally with criminals or corrupt politicians. The Nebulans, fearing the Transformers' civil war would plunge their own world back into war, finally banished the Transformers and their Nebulan sidekicks back into space, where they finally arrived on Earth.

In the TV series, the Transformers arrived on Nebulos in the three-part episode "The Rebirth", which were the only episodes of the fourth season, and the last episode ever produced in the United States. The Autobots' spaceship was plunged to Nebulos accidentally by a gigantic power surge from the Plasma Energy Chamber, and the Decepticons followed them. The TV show version of Nebulos is a hostile, dying world, where a group of eleven rulers known as "The Hive" controls the entire world from an underground city, abusing their power for their personal pleasure and oppressing the workers with various mechanical devices controlled by their minds. Upon seeing the Autobots, the Nebulon workers mistook them for machines controlled by The Hive, and imprisoned them, later to destroy them. However, an attack by the Decepticons convinced the workers that the Autobots were good guys, and so they were released and allied themselves with the workers. The Decepticons did the same with the members of The Hive (after being co-erced).

In the Ladybird books continuity, the Nebulans were a race of small transforming robots. The Nebulans have appeared once more in IDW Publishing's new continuity, in. Their planet was attacked by Thunderwing as part of an unholy pact to rejuvenate Cybertron. Despite the best efforts of the local Decepticon cell (led by Dreadwind and Darkwing) much of the planet was devastated. It also appeared chronologically earlier in the issue on Ultra Magnus, where Scorponok was already seen to be developing the Headmaster process. Nebulos was also mentioned by Swindle in the "Transformers Animated" episode, "Decepticon Air".

Nebulos is also featured in several stories of the "Ask Vector Prime" Facebook feature. Among these were the "Armada" storyline, in which the Nebulans Hi-Q and Arcana were responsible for Overload and Rollout being merged into a Headmaster being in order to save them both from debilitating medical conditions, and a split reality in which the monstrous Zarak Maximus was born from the fusion of Mo Zarak with the remains of Fortress Maximus and Scorponok.New Kaon is a planet where all kinds of Decepticons that are fleeing from the Autobots take refuge. It was featured in the comic book tie-in to "Transformers Animated".

In "", Ocean Planet was the name of a world created by Alpha Q using the power of his Energon sun. It is mostly covered in an ocean.

Paradise is a planet that is a natural wonderland of vast jungles, roaring rivers and waterfalls, smoking volcanoes, and beasts of all shapes and sizes, all co-existing in harmony with the tribes of human-like beings living there. Although choosing to live a primitive existence dressing in robes made from animal skins and living in yurts, the people of the planet Paradise defy appearances by being intelligent, well-spoken creatures.

In the "Transformers: Headmasters" episode "Head Formation of Friendship," Paradise was targeted by Galvatron and the Decepticons who were on a quest to drain the energy from planets until they are driven away by the Autobots.

Paradron is a peaceful, Energon-rich planet, accessible only through a vortex. Several Autobots fled there when the war against the Decepticons began and set up a colony there. The Autobot Sandstorm was one of the inhabitants of this planet. It was featured in "The Transformers" episode "Fight or Flee" when the Decepticons discovered this planet and enslaved the pacifist Autobots. After the Autobots rescued the pacifist Autobots, Rodimus Prime had Paradron destroyed with most of its inhabitants being transferred to Cybertron.

In Fun Publications' "Shattered Glass" storyline, Paradron was a prison planet where Optimus Prime exiled some of his more dangerous Autobot enemies, including Ultra Magnus and Wreck-Gar.

Pequod is an oceanic planet that is home to large whale-like creatures called the Klud. It was featured in Marvel Comics.

Pirate Planet is a planet where space pirates of all kinds store their loot.

In "", Plains Planet (also called Grass Planet) was the name of a world created by Alpha Q using the power of his Energon sun. It is mostly filled with grasslands.

Planet Q is a desert planet that was featured in "". It was home to Alpha Q, Scorponok, and the Terrorcons, and was consumed by Unicron prior to the start of the series. Alpha Q's desire to restore his home planet using Unicron's power served as his primary motivation throughout "Energon", and was also the reason for Rodimus' willingness to work with him.

Planet X is the name of two different planets in the "Transformers Universe, the first of which was seen in "".

The Planet X featured in "" was first seen in a recording found by the human Lori and the Velocitronian leader, Override, after the latter's battle with Scourge on Giant Planet. It was shown to be a highly advanced world like Cybertron, purple in color, with two golden rings around it forming an X pattern. Later, it would be revealed that Planet X was the dominant force in the alternate universe that Giant Planet had been drawn into. It was capable of non-orbital space travel and annihilating less advanced civilizations it came across. This, however, caused life in its universe to 'die' and, in an attempt to rectify the problem, its denizens sought out another life-rich planet to subjugate. The planet they found, Giant Planet, did not take kindly to being invaded, and its inhabitants reformatted themselves into larger forms with help of the Cyber Planet Key in order to combat the threat of the off-worlders.

Left with few options and little hope of victory, the inhabitants of Planet X powered up their ultimate weapon: a Death Star-like planetary cannon, in order to wipe out the transformers on Giant Planet. Unfortunately, the cannon was too powerful for them to control and the result destroyed their world. The survivors, including and, were scattered all across their universe, and were eventually thrown into the Transformers' proper universe. Believing Giant Planet to be at fault for their home planet's destruction, the various Transformers plotted revenge against them. In addition, the Giant Planet Transformers also felt at least partially responsible for Planet X's annihilation. This created their custom of building cities and then abandoning them, which became a perpetual, planet-wide act of penance. Eventually, Sideways and Soundwave managed to return to Giant Planet, and sought the Cyber Planet Keys in order to exact their revenge.

"Ask Vector Prime" would later feature Planet X in additional storylines, often involving its origin. In one reality, it was the broken body of Unicron from "", shunted into another dimension by the energies of the Matrix of Leadership. Arriving on the edge of the Earth solar system of that reality, Unicron set out to repair himself but was hindered by the actions of Megatron utilizing a Star Harvester. As in the "Energon" series, Unicron revived many of the Transformers he had previously consumed in an effort to expedite his recovery, and the new race renamed their home Planet X. They then traveled to the world of the "Victory" series and attacked it, but the efforts of the Autobots using Zone energy split the planet into two: the beautiful world seen in "Victory" and one virtually identical to the "Cybertron" version, which was later destroyed by the inhabitants of an alternate Gigantion known as Gigalonia. Other versions included a "Cybertron" Planet X that was once part of the Liege Maximo's Cybertronian Empire, and another in which Planet X was once the home of a smaller scale Unicron who used a cyber key to unite himself with his former homeworld and domain.

Pz-zazz is a highly technological planet. Pz-zazz was hopelessly corrupted by crime until an ancient bird icon was returned to its place and purified the planet.

Thrull is the planet that Galavatron ended up on after being thrown out of Unicron as seen in "The Transformers" episode "The Five Faces of Darkness" Pt. 1. An inhospitable world consisting of plasma lava and rock, its environment led to the degradation of Galvatron's logic circuits, making him even more unstable and dangerous than he had been previously. Upon being revived and escaping the planet, Galvatron fired an energy blast that caused Thrull to explode.

Torkulon is a planet whose main source of commerce is psychotherapy. Galvatron was brought there for treatment in "The Transformers" episode "Webworld", following his increasingly erratic behavior following the event of "". The entire planet was a living computer whose circuitry was woven by arachnid-like beings known as the Alya, and manipulated by a furry humanoid race of size comparable to the Transformers themselves. Despite multiple methods used, the Torkulon were unable to cure Galvatron, who madness infected the planet and caused it to go out of control. Galvatron himself then destroyed the Torkulon computer core, leaving the planet devastated, though with the possibility of rebuilding.

Twin Star is a group of two diametrically opposed planets Sperity and Tourin. It was featured in "".Unicron is a fictional character from the "Transformers" universe and toyline. Created by Floro Dery, he was introduced in the 1986 animated film "". and reprised that role in Atari's 2003 Transformers video game. Unicron is a prodigiously large robot whose scale reaches planetary proportions, and he is also able to transform into a mechanical planet. Unicron's origin has expanded over the years from simply being a large robot to being a God of chaos who devours realities. He often employs the help of Decepticons in his work. In some stories, he is considered part of the origin of the Decepticon forces.

Varas Centralus is a planet situated in the Kol star system. It is featured in IDW Comics.

Vehicon is a planet where Reverse Convoy is the leader of the Autobots.

Velocitron (known as Speedia in "Galaxy Force" and Speed Planet in promotional materials) is a fictional planet featured in "" and is the location of one of four ancient Transformer colonies that lost contact with the home world of Cybertron long ago, along with Earth, Jungle Planet, and Gigantion. Each of these colonies possess a Cyber Planet Key, containing a fragment of the power of Primus. The name Velocitron is used infrequently. The planet is more commonly referred to as "the Speed Planet" or simply "Speed Planet." The planet's full, formal name appears to be "Velocitron, the Speed Planet."

A variable desert planet, it was terraformed into a global race track with the pursuit of perfect speed and performance the primary motivating force in its society and culture. Disputes are settled in formal races with the winner claiming victory over the dispute as well. Automated repair machines maintain the race courses, which include tracks featuring various environments and obstacles as well as simpler straightforward courses. Characteristics of Velocitron's inhabitants include translucent wheels of unknown material, and double-barrelled long-range weaponry.

The planet's leader is Override as she is the fastest of all Velocitronian Transformers with no equal planetside. She holds semi-annual planetwide races to determine the next leader with the planet's Cyber Planet Key (which exists in the form of a trophy called the Planet Cup) awarded to the winner. The location of Velocitron was first re-discovered by Megatron using the map he had stolen from Vector Prime. Vector Prime himself later located the planet as well, by studying a copy of the Atlantis Pattern found at a museum in Mexico.

Hot Shot felt right at home on the planet and participated in the planet-wide race alongside a few of his Autobot comrades, despite reservations by Optimus Prime who advised them not to interact with any of the inhabitants. Despite quarreling with his companion Red Alert, Hot Shot managed to overcome the challenges of Speed Planet and won the great race. In addition to gaining Override's friendship, the Autobots also learned a valuable lesson about interacting with the inhabitants of the different planets. The starship that carried the Cyber Planet Key to this world was named "Ogygia".

In the final episode of "Transformers: Cybertron" the ""Speedia 500"" race is held to determine the leader of Velocitron, which Hot Shot wins. Dirt Boss comes in second, Ransack in third, Dark Crumplezone in fourth, Brakedown in fifth, and Clocker in sixth. Override didn't even compete, as she joins the new Space Bridge project led by Optimus Prime. The name of the race is a reference to the Japanese name of the planet, which is Speedia.

Velocitron is one of the planets mentioned in the first chapter of "" in which many Cybertronians are populated. The sequel novel "" features Optimus Prime and the other Autobots aboard the "Ark" coming to Velocitron where they meet Blurr and Override. Velocitronians are obsessed with speed, so that their lives are centered around going faster or helping others race. The Autobots soon discover a war brewing on Velocitron between Override and Ransack, the former sympathizing with the Autobots while the latter finds Decepticon philosophies more appealing. The two sides soon see conflict, and after the Ark's departure are visited not only by Megatron and the Decepticons but also by a group of pirates known as the Star Seekers under Thundertron. Velocitron in this continuity is also threatened by the instability of its sun, which is threatening to go supernova.

"" included a mention of Velocitron by that series' version of Blurr, who notes that it consists of "all roads, no speed limits."

Known inhabitants of Velocitron are:Vs'Qs is actually a moon, not a planet. Vs'Qs is a barren, desolate place, devoid of any natural life. Vs'Qs was the place where the body of Optimus Prime happened to land on, having been blasted off into space randomly after his death. The Matrix of Leadership contained within the body was found during the Matrix Quest.

Cybertron is a fictional planet, the homeworld of the Transformers in the various fictional incarnations of the metaseries and toyline by Hasbro. In the Japanese series, the planet is referred to as "Cybertron" (first shown on Japanese "Galaxy Force" packaging, although "Cybertron" is the Japanese name for "Autobot") pronounced as Sabertron セイバートロン "Seibātoron". Cybertron is populated by mechanical self-configuring modular lifeforms of variable size who can transform into all kinds of machinery. These are called Cybertronians, or Transformers.

Cybertron

Iacon is the name of the largest city on Cybertron, in the various Transformers media. It is best known as the hometown of Optimus Prime and the Council of Autobot Elders. The city was protected by a great dome, and was the last city-state to fall to the Decepticons, after which the Autobot resistance moved into the tunnels and bases beneath its surface. Iacon appeared throughout the US and UK Transformers comic as the main base of the Autobot resistance on Cybertron.

"And There Shall Come... A Leader", a flashback story in the 1985 UK Annual, shows Iacon as home to the Autobot Council of Elders based in the Celestial Temples, who include Emirate Xaaron, High Councilor Traachon and Councilor Tommandi. The city itself is protected by a great dome, and is the last Autobot outpost to hold out against Megatron's advancing army of Decepticons. During the story, Prime’s troops destroy the main expressways into Iacon, halting the Decepticon advance.

In the 1986 UK Annual, another flashback story, "State Games", details pre-war Cybertron and the buildup to Megatron’s uprising. After the failure of a global ruling body known as the Overlords, Cybertron has been divided into various independent city-states, all of which are now facing overcrowding and a lack of resources. Iacon is the largest and wealthiest of these city-states, and the home of Optimus Prime. Inter-state gladiator matches increase the tension between Iacon and lesser city-states such as Tarn and Vos, and eventually a botched act of sabotage leads Tarn and Vos into civil war with each other. The survivors are united by Megatron, and blame Iacon for standing by and, falsely, starting the conflict in the first place.

In the storyline (UK #66 to #88), Iacon is revealed to have been conquered by the Decepticons and its dome is a broken shell. Emirate Xaaron now leads the Autobot resistance movement from secret bases beneath Iacon’s surface.

The Autobot resistance moves out of Iacon and into the city-state of Kalis in the "City of Fear" storyline (UK #164 to #169), but are back in Iacon by "Yesterday’s Heroes" (UK #252 to #254, US #60). Whether Iacon survives Unicron's attack in "On the Edge of Extinction" (UK #319 to #322, US #75) is not made explicit.
Cybertron is described in the first issue of the Marvel comic book as being the size of Saturn, which would logically mean it possessed incredibly dense gravity, and yet it did not, possibly as a result of its hollow structure, honeycombed as it is by tunnels. However, in later depictions the art suggests Cybertron is much smaller, particularly during the attack by Unicron (detailed in "On the Edge of Extinction" in UK #319 to #322, US #75), where the scale differences between humans, individual Transformers and the ‘planet-sized’ Unicron suggest Cybertron to be closer in size to the earth's moon, as depicted in the cartoon continuity.

Cybertron has a metallic surface, although whether this extends to the core is debatable: in "The Legacy of Unicron" (UK #146 to #151) and later in "Primal Scream" (UK #259 to 261, US #61) it is revealed to have originally been ‘space junk’, the composition of which is unknown. The atmosphere is breathable by carbon-based life, but liquid water is rare enough on the planet that its existence is in doubt. Cybertron previously orbited Alpha Centauri, but was later thrown out of orbit and sent wandering through the galaxy.

Before the Big Bang, an older universe existed, which was destroyed - consumed - by the fallen deity, Unicron. In the void of nothingness left in the universe's wake, Unicron slumbered, his work done... but Unicron had not been thorough enough, and tiny particles of the old universe that remained reacted with one another, birthing the current universe we know today. When Unicron awoke, his task began again, as he consumed world after world, until the sentient core of the universe responded by creating a guardian to battle Unicron – the Lord of the Light, Primus. Unfortunately, while Primus proved to be a physical equal, he was unable to outmatch Unicron in power. In a bid to save the worlds that they were destroying with the ferocity of their battle, Primus shifted the conflict to the astral plane, though he fared no better there than in the physical world. In a final gamble, Primus returned to the physical universe, with Unicron following on his heels, eager for the kill – unaware that Primus was luring him into a trap. Rather than materializing back in their corporeal forms, Unicron and Primus's consciousnesses became imprisoned in two metallic asteroids; Primus had sacrificed himself in order to capture Unicron.

However, Unicron was not beaten. After millennia, Unicron was able to psionically reshape his asteroid prison into a massive metal planet, and from there further developed his prison to be capable of transformation into a robot form which mimicked his original appearance, allowing him to continue his attempts to once again destroy all of creation. Primus followed suit, crafting his asteroid into a similar metal world – Cybertron. However, he did not wish to make the mistake of simply re-engaging Unicron in personal combat, as he believed their battle would continue to be a stalemate given their previous conflict. Instead, he gave birth to a race of beings called Transformers, possessed of transforming powers like Unicron's, and he bestowed upon them the Creation Matrix, a genetic Matrix that contained his essence, as capable of creating life as Unicron was of destroying it. Ultimately, the Matrix was intended by Primus to be a weapon intended to destroy Unicron, which would be wielded by Primus' creations against the evil entity. To hide his creations from Unicron before he felt they were ready to face him, Primus went into a hibernation-like sleep, his massive visage nestled at the planet's heart.

Knowing nothing of their true origins or the destiny they were to fulfill, the Transformers eventually splintered into two factions – the politically dissident Decepticons, who waged war on the peaceful Autobots. Megatron, leader of the Decepticons, schemed to turn Cybertron into the ultimate weapon, a warworld that would wreak havoc across the galaxy, and the resulting war knocked Cybertron out of its orbit and set it adrift in the universe. Around four million years BC, Cybertron's path brought it into the Sol system, heading directly for the asteroid belt, which threatened to heavily damage the planet. Autobot leader Optimus Prime led a contingent of his warriors aboard the Ark to destroy the rocks in Cybertron's path, but once they had succeeded, they were attacked by the Decepticons, causing all involved to be trapped in stasis on prehistoric Earth.

While the Autobots and Decepticons aboard the Ark were trapped in stasis, life on Cybertron continued. Consequently, the young warlord Trannis took control of the Decepticon army on the planet, and led a fierce campaign against the Autobots, reclaiming the cities they had taken, levelling the capital city-state of Iacon, and executing the Autobot council of elders, save for Emirate Xaaron, who fled with his troops and continued to fight. Xaaron formed an elite Autobot strike team, the Wreckers, who succeeded in assassinating Trannis, only to have the conflict escalate when the even more dangerous Lord Straxus took his place, forcing Xaaron and his men into hiding, fighting a guerilla war from a number of "Autobases" across the planet, headed up by Fortress Maximus and Perceptor, among others. Maximus's team, however, soon abandoned Cybertron, tiring of war and seeking peace on the planet Nebulos.

When the Transformers stranded on Earth were reactivated in 1984, the Decepticons succeeded in getting a message to Cybertron, and Straxus responded by arranging for the construction of a space bridge between the worlds. In a confrontation with Blaster aboard the bridge, Straxus's body was destroyed, leaving him a severed head, which in turn forced him to attempt the mental possession of Megatron's body. Megatron did not take kindly to this, and retaliated by destroying Straxus, leaving the Decepticon fuel auditor, Ratbat, as Cybertron's local Decepticon commander.

Little of import occurred on Cybertron in the immediate future as, more and more, the war spilled over to Earth, with the Autobot and Decepticon commanders summoning more and more warriors to the planet. Ratbat's death in the Underbase affair allowed a triumvirate of three Decepticons – Siezer, Legonis and Octus – to established themselves as rulers on Cybertron while Scorponok led on Earth, but following their destruction by Megatron, and his own subsequent disappearance, their appointed replacement, Thunderwing, took control and dispatched the Mayhem Attack Squad to track down the Autobot Pretenders. When the ensuing battle resulted in the malfunction of a teleportation portal, Grimlock, Bumblebee and Jazz found themselves at the core of Cybertron, bearing witness to the visage of Primus, and learned of his legend from the ancient "Keeper". The Keeper was then struck down by the Mayhems, and the battle that followed briefly awakened Primus, who unleashed a single scream that was heard on the fringes of known space... by Unicron.

As Unicron bore down on the planet, he sent an agent, Galvatron, ahead to sow terror in his name. But Galvatron chafed in Unicron's service and instead awoke Primus, who possessed Emirate Xaaron and teleported every Transformer back to Cybertron in order to unite them, as Unicron attacked the planet. Although Optimus Prime was able to use the Creation Matrix to destroy Unicron, it seemed that Cybertron was to meet its end by other means - tremors and storms began to pervade the planet, which seemed to be tearing itself apart, forcing the remaining Autobots and Decepticons to flee. In actuality, however, the final wave of Matrix energy released in Unicron's destruction had begun a planet-wide rebirth, which was then guided to conclusion by the Last Autobot, restoring and regenerating Cybertron, which the Autobots then occupied.

The above is the story of Primus as related in the United States in Marvel Comics but the story was originally told in British comics. The Primus story is recounted three times under Simon Furman - in order: Transformers UK #150, Transformers US #61, and US #74, and while the Primus/Unicron battle and ultimate solution are always the same, the background to their fight differs in each telling.

The first (told by Unicron) has Primus and Unicron leading armies of similar beings at the dawn of the universe. The second (told by the Primus Chamber's Keeper) had the two as the last of their respective pantheons and Primus needing to stop Unicron before he could pass on from this realm. The third, told by Primus, has Unicron destroying the previous universe and trying to end the current one, with Primus being formed by the "sentient core" of this universe to stop him.

By the third re-telling, the idea that Unicron and Primus were related to similar entities had been dropped and was not picked up again.

In the sequel series to the original "Transformers" comics, more of the history of Cybertron and the Transformer race was revealed, as Optimus Prime discovered that they had once possessed the ability to asexually reproduce by "budding". This was an ability that ceased to function and was forgotten as part of Primus's design, but a group of Cybertronians discovered it and unlocked it within themselves. They continued to multiply beyond the intended limits of their race, diluting their essences until all that remained were single minded killers arrogant in their own supposed superiority - and The Swarm, a dark, destructive byproduct of the reproduction which ventured into space and destroyed other worlds and races, just as these "second generation" Cybertronians left Cybertron under the command of Jhiaxus, and began colonising other planets. When the Swarm returned with the intention of consuming Cybertron, the world of its origin, Optimus Prime used the Matrix to purify it.

In the TV series, Cybertron is a planet once used by the Quintessons as a factory with assembly lines creating soldier ("military hardware") and worker ("consumer goods") robots. (Note: This seems to contradict material presented in the first two seasons of the series. The whole series is full of apparent contradictions and inconsistencies.) Following a rebellion which drove the Quintessons off the planet, the workers became the Autobots and the soldiers became the Decepticons. These two factions eventually engaged in civil war, which forms the basis of the various "Transformers" stories. Some time between the Quintesson occupation and the Autobot/Decepticon war, Cybertron entered a "golden age", with the planet becoming an actual gold color. The energy demands of the war eventually returned Cybertron to its original coloration.

Cybertron, as presented in the original "The Transformers" animated series, was considerably smaller than the planet Earth, though "how" much smaller it was presented as was inconsistent, as were many other things in the series. Entirely metallic on the surface, some of the lowest levels of Cybertron consist of rock and dirt, suggesting a natural beginning to the planet. Its gravity is light enough that humans are able to traverse the surface without any trouble, and it possesses a breathable atmosphere. Water is not uncommon on the planet – lake and rivers have been shown to exist, albeit sparingly. Cybertron is orbited by at least two unnamed moons, but its own place in the cosmos appears unfixed – in 1984, it was clearly shown to exist outside of the Milky Way galaxy; however, nine million years prior, Starscream and Skyfire had been able to fly from the planet to Earth under their own power, suggesting that it may drift freely through space, and had been passing through the Solar system at that point, going on to drift out of the galaxy over the ensuing millennia. Cybertron's moons did not appear until the animated feature "", and no explanation for their existence was given. The moons were also depicted as being mechanical in nature much like Cybertron with metallic surfaces. Unlike Cybertron however, the moons do not appear to have any detectable atmosphere, as Daniel Witwicky, a longtime ally of the Autobots, was required to wear a mechanical "exo suit" that presumably included its own air supply and means to keep organic life forms pressurized against the vacuum of space, something that is not required by humans on Cybetron.

In the first episode, "More Than Meets the Eye Part 1", the dome structure of Iacon retracts to reveal a launching pad for the Autobot spacecraft the Ark. After Autobot leader Optimus Prime and Decepticon leader Megatron journeyed to Earth, crash landing four million years ago and entering emergency stasis lock, Shockwave keeps the planet in stalemate until Megatron awakens in 1984. Cybertron's point of origin within the galaxy was never revealed in the original cartoon, but originally required a dimensional space bridge in order to return to the planet from Earth. Later stories depicted the ability to travel to Cybertron via the use of three interstellar Transformers; Skyfire, Astrotrain, and Omega Supreme. During the first two seasons of the original cartoon, Cybertron was brought into the solar system, and twice was close enough to Earth to be seen by the naked human eye.

Travel between Earth and Cybertron became roughly a half a day's journey, as depicted in the 1986 feature film "". The Decepticons have conquered the planet by 2005, and Cybertron is seen to have at least three moons, two of which are consumed by Unicron. In the aftermath of Unicron's attack on Cybertron, and subsequent defeat, the Autobots are able to reclaim the planet, forcing the Decepticons to retreat to Chaar, a blackened husk of a world. In the final part of "The Rebirth", Vector Sigma absorbed the energies of a near-supernova sun, energizing Cybertron and bringing about a new Golden Age. Unicron's head became an artificial satellite for much of the third season, after his body was destroyed and was reactivated at during the episode "Ghost in the Machine", though it appears to have gone dormant again afterwards. It is unknown what became of Unicron's head when Cybertron was moved into near-Earth orbit during the "Rebirth" episodes, but by the time of "Beast Wars" it is shown that it no longer orbits the planet.

While the American "Transformers" series was concluded with the three-part miniseries, "The Rebirth" (set in 2007), in Japan it was opted to continue the series, and so "The Rebirth" was disregarded in favour of producing "Transformers: Headmasters", a full-length 35-episode series set in the year 2011.

In 2011, it was discovered that the release of the energy of the Matrix by Optimus Prime to cure the Hate Plague had much more far-reaching consequences that anyone suspected. With the Matrix's energy depleted, Vector Sigma's balance – previously tilted in favour of the Autobots by the existence of the Matrix – was reset to neutrality, allowing the Decepticons, bolstered by their new Headmaster troops, to freely invade Cybertron "(known as Seibertron in Japan)". Eventually, this forced Optimus Prime to sacrifice his life by merging with Vector Sigma in order to stabilise the computer before it destroyed Cybertron from within.

Not long thereafter, Vector Sigma developed a new metal alloy dubbed Cybertonuron, which enticed Galvatron into another raid on the planet. However, the Decepticon Headmaster leader, Zarak feared the power that Galvatron would gain from the alloy. To prevent either him or the Autobots from obtaining it, Zarak arranged for his Headmasters to plant bombs at the core of the planet; Vector Sigma's chamber. The Autobots were unable to stop the countdown and the bombs detonating, tearing Cybertron apart and leaving it a charred uninhabitable ruin drifting in space.

Dorling Kindersley's "Transformers: The Ultimate Guide" included illustrations and descriptions of Cybetron’s surface, including an image of Iacon itself. The Guide, first published in 2004, drew on both the Marvel comic continuity and the then recent depictions of Cybertron and Iacon from the Dreamwave "" comic book series. This included elements such as the Stellar Galleries from the latter series, not documented in the original Marvel run. It also depicted Cybertron in a fully realized 'robot mode' as Primus, something never even hinted as a possibility before in the original toyline or comics by Marvel, but which became a reality in, which was the first television series to not only depict Cybertron as having the same transforming capability as Unicron, but also showing it occurring within the show.

In the IDW comics, Cybertron orbits Lambda Scorpii and has been rendered mostly uninhabitable by the war. While Transformers can survive on the surface, they cannot live there indefinitely.

Simon Furman, creator of the Primus backstory for Transformers, has stated there will be "no Primus. No Unicron" in the IDW Generation 1 comics, and that if Cybertronian prehistory is featured it will be different from previous takes; IDW's publisher confirmed there will be a story featuring Transformer prehistory. While a character exclaims "Primus!" in "Megatron Origin" #4 (by a different writer), Furman stated in his blog comments "doesn't necessarily mean it's G1 Primus. There are still no plans to do feature [sic] Primus (as was)". He does say it is possible a different being called Primus could have existed.The Cybertron of the "Beast Wars" era is set some 300 years in the future of the original Transformers G1 continuity, drawing on elements of both the animated series and Marvel comics. With the aid of humankind, the Autobots were finally able to succeed in defeating the Decepticons, some of whom were granted amnesty. Subsequently, new energy-conservation methods resulted in what was termed "The Great Upgrade", a planet-wide upgrade of Autobot and Decepticon into new, human-sized, more energy-efficient forms, leading the races to rename themselves "Maximals" and "Predacons", respectively. Transformers are now created through the use of "protoform" technology – produced in Maximal and Predacons facilities nicknamed "The Matrix" and "The Pit" respectively (after the respective Transformer afterlives), protoforms consist of an endoskeleton surrounded by a nanotech gel that reconfigures with the scanning of an alternate mode. By this time, it is apparent that Cybertron has settled into orbit around a star again, and has acquired a new moon.

Cybertron's robot mode, Primus was never seen or mentioned in the original U.S. Transformers television series, the writers of "Beast Wars" included Primus to the television mythos with mention of Primus by the Transformers in that series, and the creation of the Covenant of Primus in the series finale.

The expanded fiction of the Botcon and OTFCC comic books suggest that Primus experimented with a small planet before actually transforming himself into Cybertron. This world, named Protos, was where he created the first 12 Transformers, each of them themed after an animal of the zodiac. Later, Primus created the Original Thirteen Transformers.

Primus appeared with Alpha Trion in the "Transformers: Universe" comic, bringing back Optimus Primal and guiding him in his battles against Unicron allied Decepticons.

Cybertron's governing structure during the Beast Wars era is based upon the Pax Cybertronia (Peace of Cybertron). The peace on Cybertron is maintained through a treaty known as the Pax Cybertronia, which – perhaps unfairly – ranks the Predacons as second-class citizens, with the Maximals in control of the planet. Each side is governed by a council;the Maximals governing body is known as the Maximal Imperium while the Predacons' version, the Tripredacus Council, operate out of a satellite orbiting the planet or star, quietly working to their own agenda... an agenda that was sorely disrupted by the rise to power of the renegade, Megatron, who stole a ship and escaped to prehistoric Earth with the intent of altering time.

There are many distinct areas of Cybertron. Ranging from locations on the surface, to any of the number of buried ruins. In "The Reformatting", the first episode of the "Beast Machines" TV show, the Maximals discover the remains of Iacon on Cybertron, deep beneath the planets current surface. The episode suggests that in the intervening years between the end of the G1 / G2 series and the start of "Beast Wars", the inhabitants of Cybertron have built over older city-states with new cities, in a similar manner to an onion skin.

As alluded to in Beast Wars, there is a giant amusement park near the northern pole of the planet. Orbiting Cybertron are a number of structures, such as starports and bases. The Tripredicus Council is established on one of these orbiting bases. There are also a number of communication satellites.

Beneath the cityscape surface of the planet lies layer upon layer of earlier civilizations. One entire Autobot era city lies just beneath the surface. Beneath this city lies ruins of older Cybertronian civilizations, all ending in the rocky core of the planet. It is here that the Oracle of Vector Sigma lies. It is also here that the techno-organic core can be accessed.

In the two groups' absence, Cybertronians had undergone another modification called the "Quantum Cycle Upgrade", in which they were individually fitted with alternate mode scanners so they would not have to rely on external mechanisms to do the job for them. Striking fast and hard, Megatron unleashed a transformation-freezing virus on the populous and deployed a small army of "Vehicon" drones, who extracted the sparks of the virus's hapless victims. Their shells were then used to create more Vehicons, and so it continued until the entire population of Cybertron had their sparks removed, and all that remained were the Vehicons, united under the singular, guiding intelligence of Megatron, who, for all intents and purpose, was now Cybertron itself.

Megatron's perfect technosphere was shattered with the return of Optimus Primal's Maximals, arriving in their intended time period to discover Megatron's mastery of the planet. Reformatted into new technorganic bodies by the Oracle – the shell program that now surrounded Vector Sigma that enabled users to commune with the afterlife dimension called the Matrix – the Maximals subsequently discovered that Cybertron had indeed been an organic world before it acquired its current metallic shell. Uncovering the planet's gelatinous, organic-matter core, Primal believed that the Oracle had charged him with restoring the organic to Cybertron, only for a failed gambit involving the Key to Vector Sigma and the Plasma Energy Chamber to show him the error of his ways - the Oracle did not desire one element to dominate the other, but for a techno-organic balance to be achieved. Even as the body-shifting Megatron attempted to absorb the entire planet's sparks into his own, creating a singular consciousness, his and Primal's final battle saw them tumble into the planet's core, where Primal initiated a planet-wide reformatting, transforming the entire world into a techno-organic paradise.

The "" version of Cybertron is never seen (save for once in a flashback in "Ultra Magnus" and "Ultra Magnus: Forced Fusion"). The entirety of the series takes place on Earth. It is unknown what cities, or Autobots and Predacons that could be there, but it is presumably a still living planet. Whether or not it is Primus is unknown. Primus was not mentioned at all, nor Unicron, but Vector Sigma and Alpha Trion exist, as well as the All Spark.

The little information on Cybertron established in the series is that Cybertron was located near or orbiting a larger ringed world, and had an asteroid prison colony in which dangerous Decepticon and Predacon prisoners were interred. At one point there were a series of civil wars, in which Optimus Prime and Ultra Magnus, both creations of Alpha Trion, fought side-by-side. Following the wars, Magnus was honored, but Vector Sigma selected Optimus as Autobot leader and bestowed on him the Matrix of Leadership. The Predacons on Cybertron were ruled over by a council, of which Megatron was a subordinate, though he once claimed to be "leader of the Predacons and future ruler of the galaxy" and that he was already "ruler of many worlds".

Cybertron is the home planet of the Transformers in the three television series, "", "" and "". In the miniseries, Cybertron, Primus' material body, is inhabited by Mini-Cons as well as Autobots and Decepticons, who are unaware the Mini-Cons were weapons forged by Unicron. The war between the Autobots and Decepticons is escalated by Megatron's attempt to gather them. During the escalation, the Mini-Cons liberate themselves and leave the planet in a mass exodus, leading to a four million years (one million years in the Dreamwave comic) stalemate between the two principal forces. Ten years of peace follow "Armada" (2002–2004) and then "Energon" (2014). After "Cybertron"'s climax, the planet has an atmosphere more suitable for humans and organic wildlife.

According to Hasbro, Cybertron orbits the star Alpha Centauri and is about the size of Saturn. At some undefined point in Cybertron's ancient past, it was attacked by Unicron, who was fended off by the planet's guardian, Omega Supreme. Omega and four other guardians subsequently entered stasis below the planet's surface, guarding a reservoir of "Super Energon" for its use in the future. Few other facts from this Cybertron's history are available - it is not clear when the Autobots and Decepticon began warring relative to this event. The presence of a sentient energy core named "Primus" at the heart of Cybertron in the "Armada/Energon" universe suggests its history is some variation of the Primus/Unicron legend. An American-written trading card suggests a story similar to that of the Dreamwave universe - Primus and Unicron are twin heralds, but Unicron turns on Primus and fells him, casting his body into the orbit of a nearby star (alpha Centauri). The card does not state that Primus became Cybertron, but it can be assumed with some degree of certainty.

Long ago, Cybertron was peaceful, until the evil Decepticons waged war against the Autobots. Both sides fought for control of the planet, each ruling one half. Eventually, a mysterious, unclarified "cataclysm" struck the planet, following which the small race of robots known as the Mini-Cons emerged. It would later be discovered that the Mini-Cons were creations of Unicron – currently orbiting Cybertron in a weakened state, disguised as a moon – who had implanted his cells within Cybertron, where they grew and hatched into the Mini-Cons; presumably, then, the cataclysm was caused by Unicron's implantation of his cells. The larger Transformers on Cybertron soon discovered that the Mini-Cons possessed power-enhancing abilities, and began to war over the small robots (it is unclear if the Autobots and Decepticons were already at war, or if it was the emergence of the Mini-Cons which began the conflict).

Through a complicated instance of time-travel, however, the Mini-Cons had the seeds of souls and sentience planted within them at the moment of their creation by a group of time-displaced human children, and as they came to think and feel for themselves, they sought to fulfill their own destiny, by going to Earth to find the humans. The Autobots agreed to aid the Mini-Cons, preferring that they be free and not subject to anyone's will, but the Decepticons still sought to control them, and attacked the launch of the Mini-Con ship, which was crippled as it escaped through a portal, causing it to crash-land on Earth, where the Mini-Cons remained dormant for a million years until they were awakened by the very humans they had come to find. The signal released by their awakening brought the Transformers on Cybertron to Earth in pursuit of them.

Some time into the conflict on Earth, several Autobots and Decepticons followed Optimus Prime and Megatron's teams to Earth, where the battles eventually culminated in Megatron attaining possession of the three Mini-Cons weapons. Returning to Cybertron, he used the weapons to cut a swathe of destruction across the planet, quickly establishing control over the vast majority of it. However, the sudden escalation in the Autobot/Decepticon war caused by the Mini-Cons' reawakening had resulted in a vast increase of the hatred and "negative energy" that powered Unicron, who soon shed his moon disguise and attacked the planet in his re-energized gargantuan robot form. Cybertron took heavy damage from the planet-eater, but by rescuing the Mini-Con weapons from within his body, the Transformers were able to briefly halt his rampage - until Megatron (now Galvatron) challenged Optimus Prime to a final duel, the ferocity of which began to awaken Unicron once again. In the end, Galvatron sacrificed himself to break the circle of hate, leaving the Decepticons allied with the Autobots, working together to restore their shattered world.

As part of the rebuilding program, the Autobot-Decepticon alliance entered into a partnership with Earth's governments to mine Earth and the Sol system for the energy-rich mineral known as Energon. Over the next ten years, Cybertron was steadily restored as "Cybertron Cities" were built in strategic positions on Earth, its moon and Mars to gather Energon and keep the planet rich and healthy.

Following Megatron's resurrection through the power of Energon, he began a quest to restore Unicron to life, under his control, which eventually led him to move the planet-eater's body through a spacebridge into the vicinity of Cybertron itself. After a series of attacks on the planet, during which Primus's chamber was penetrated by Terrorcons, a reaction between the negatively charged Energon within Unicron's body, and the positive Energon used by the Autobots caused a rupture in space, leading to a new sector of the universe where the planets consumed by Unicron had been recreated. A series of battles followed which eventually resulted in Unicron's restoration and destruction, save for his consciousness, which continued to exist within Megatron.

Guided by Unicron, Megatron gathered the remnants of his army and attacked Cybertron once more, using the destruction as a cover for his true motive – to acquire the power of the Super Energon, which transformed into Galvatron. With the aid of Sixshot, the Decepticons were then able to seize control of Cybertron's computer systems, enshrouding the surface of the planet in a poisonous Energon gas that kept the Autobots at a distance while the Energon Towers were used to propel Cybertron through the spatial rift, into the new region of space. Its motion slowed by a giant-sized, Primus-empowered Optimus Supreme, Cybertron was liberated from the Decepticons when Galvatron turned his attention away from it, using the Super-Energon to grow to colossal size himself and departing the world, heading out to find Unicron's spark, drifting in space.

When Galvatron was subsequently possessed by Unicron's spark, Primus used the Super Energon to create a foundling sun, into which Galvatron plunged himself, preferring to perish than to allow himself to be controlled. But, while appearing to be the end of Unicron's threat, in truth, it was the beginning of a much greater danger...

Primus's plan to contain Unicron's spark within the Energon sun was doomed to failure – close to a decade later, the sun collapsed in on itself, turning into a gigantic black hole which threatened not merely Cybertron, the fabric of reality and the multiverse itself, causing ripples throughout space and time that disrupted history, causing inconsistencies between the "Cybertron" animated series and its predecessors. Many Transformers were forced to depart for Earth while the Autobots search for the Cyber Planet Keys to save their world. Over time, it would turn out Cybertron was a dormant Primus. After the destruction of the black hole, Primus turned back into Cybertron with cities, atmosphere for humans, roads and wildlife.

In 2006, a toy of Cybertron was released as part of the toy line. The toy transformed from planet mode into Primus, the Transformers creator. Of the many cities sculpted into the toys surface, one, painted in gold, clearly resembles the illustration of Iacon from "The Ultimate Guide".According to "" comic book by IDW Publishing, Optimus Prime and Megatron co-ruled Cybertron. The Allspark is responsible for giving life to the Transformers. When Megatron begins a war to control it for himself, Optimus sends it into the depths of outer space in the hope that he can defeat him quickly. The war drags on, and Optimus sends Bumblebee to retrieve it, because its absence will cause the planet to shut down. It would later be revealed in the third film that Sentinel Prime was the Autobot leader when the war began and was seemingly killed as he attempted to flee Cyberton with a super weapon. Optimus then took over full command, with the rest of the events likely playing out the same way.

Cybertron's upper layers seem to have a lot of interlocking hexagonal shapes, and several battles near the end of the war took place there. Sentinel Prime used these geographical features to his advantage when he attempted to escape Cybertron aboard the "Ark". Later on, Sentinel Prime attempted to teleport Cybertron via the space bridge-forming pillars from his ship, the Ark in order to acquire Earth's resources to re-energize Cybertron. However, Bumblebee destroyed the master pillar and Cybertron collapsed as it was going through, presumably destroying Cybertron forever.

Geography-wise, the surface of Cybertron is a mystery. Large rivers of liquid criss-cross the planet, though whether this is lava, molten metal, or possibly energon is anyone's guess. In more urbanized areas, such as the city of Tyger Pax, the stone and lava seem to be covered over with steel or other refined metal. However, these incidents took place during the war, so it may have been the result of the devastation Cybertron saw. This liquid is even on the tops of buildings. Internally, Cybertron has similar features to the inside of a "Transformer", including gyroscopic joints. While everyone had abandoned Cybertron, the twin Autobot Skids and Mudflap hung out there for a while, and Starscream began organising an army there in secret. The location on Cybertron that is named after Primus is surrounded by the Rad Zone and Uraya.

Cybertron was a world created by a device known as the AllSpark. With its power, it created a race of dimensional travelers, the Thirteen Primes, and made Cybertron suitable for their habitation. The Primes soon discovered that while the AllSpark's power was vast, it was also finite, needing to be recharged. The universe soon provided the answer, for a nearby star went nova, recharging the AllSpark. Though the Primes could travel dimensions, they needed help locating stars and harvesting their energy. The AllSpark responded by creating two things to help the Primes. The first gift was the second race of Cybertronians, the Transformers, who could change their forms. The Thirteen Primes ruled over the Transformers with their descendants, forming the Dynasty of Primes, to protect the AllSpark and Cybertron, while seeking out stars to harvest. The Dynasty even shared their dimensional traveling abilities with the Seekers, those tasked with finding stars. Once they found a star, the Dynasty would follow with builders to forge a harvester to drain a star of its energy and send it to the AllSpark to form energon. The second gift the AllSpark gave the Dynasty was the Matrix of Leadership, a key which contained the essence of the AllSpark and powered the harvesters. The Dynasty of Primes recognized the potential for destruction the harvesters presented, so they decreed that any star system which supported life was to be spared.

One day, the Dynasty of Primes and their attendants came to a world to harvest its star. Just as the harvester was completed, the Primes discovered primitive but sentient creatures. Twelve of the Primes upheld the sanctity of life, but the thirteenth despised the creatures as insects and sought to steal the AllSpark's power for himself. What followed was the very first battle of Transformer against Transformer, as the rogue Prime and his loyalists waged war against the Dynasty of Primes and their loyalists. The rogue Prime murdered eleven of his brothers, but the twelfth stole the Matrix and hid it a tomb forged from the bodies of his brothers, sacrificing his own spark to seal the Tomb. The rogue Prime, now known as The Fallen, dispatched the Seekers to find the Matrix. When he returned to Cybertron, he brought his war there as well, killing the rest of the Primes and destroying his brothers' sarcophagi to prevent them from returning. However, he expended much of his power in this process and withdrew to his own sarcophagus to heal. It was there that he learned that he'd made two mistakes: First, the spirits of his brothers were able to seal him in the sarcophagus, preventing him taking over Cybertron. Second, the warriors of the Dynasty had managed to save a single orphan, hiding him from the Fallen. The Dynasty of Primes passed into the realm of legend.

Eventually, what little the Transformers knew of their origins would be lost to time. A new society arose, known as the Autobots. The Autobots were a peaceful people, led by Optimus Prime, head of the Science Division, and Protector Megatron, head of the Defense Force. The two leaders created a balance; Optimus was fair while Megatron was firm. Their world's main cities included Tyger Pax, Metrotitan, Simfur, and the capital city of Trypticon. Another area of importance was Burthov, where the Science Division had many facilities. In time, the Autobots began work on a dig near the Simfur Temple, discovering the remains of the Twelve's sarcophagi and the intact sarcophagus of The Fallen. At the same time, unknown alien hostiles attacked Cybertron. Megatron had Optimus remove the intact artifact to his quarters to better protect it, allowing him to come under the influence of The Fallen.

As Megatron began to grow more aggressive, Optimus discovered that he was the orphaned Prime hidden away when the Dynasty fell. Megatron raised an army, the Decepticons, and sought to take the AllSpark to conquer the universe. However, most of the early Decepticon forces left on the "Nemesis" with The Fallen and Soundwave to seek out the harvester. With the number of Megatron's Decepticons now diminished, Optimus assumed his proper title and raised his own army of Autobots. In the war that followed, Cybertron was decimated. Prime eventually sent the AllSpark through a wormhole into deep space, and Megatron pursued it. Both were lost. Without the AllSpark's power, Cybertron became a dead world. The Autobots and the Decepticons scattered across the galaxy, hoping either to create a new world or locate the AllSpark and restore Cybertron. A number of Transformers remained, with the Decepticons centered in Trypticon (now a "Decepticon" capital), but this didn't last long.

Note: Information in "italics" occur in the alternate storyline where Megatron won the battle for the Allspark.

"Cybertron's status was unknown, with everyone abandoning it as it began to die. However, Stockade and a group of Decepticons remained, staying alive by using Nucleon. Stockade believed they could renew Cybertron by summoning a new power source, one related to the AllSpark. They succeeded in summoning such an energy being, which did enter Cybertron to renew it and to everyone's horror, announced itself as Unicron, the Anti-Life! "

"The possessed Cybertron was swiftly altered into a scarier-looking form with a large mouth and grasping prongs, turned hostile to those on it, and warped to the Sol system. The Autobots and Decepticons were able to destroy Unicron, but Cybertron was left in its transformed state and seemingly in the Sol system, as well as continuing to be dead and powerless."

"When the Autobots were ordered off American soil, they regrouped "under" Cybertron and began working on the teleportation engines that Unicron had left there when he transformed the planet. Using these, they were able to make a decisive strike by teleporting the entire Decepticon army to Cybertron, then teleporting "Cybertron" to the far reaches of space. With the engines now burnt out and no energy on the planet, the Decepticons were marooned there, at the cost of the Autobots never being able to go home."

In the early-21st century live-action film trilogy directed by Michael Bay, Cybertron is depicted much in the same way as in the source material: the homeplanet of the Transformer race. As described in the first film, the AllSpark is the origin of life in Cybertron, and over millennia, its population grew and developed a global state, peaceful and just, remaining so for eons until the war for possession of the AllSpark broke out. The war was so devastating that it ravaged the planet until it was consumed by death, and the only way to restore Cybertron to its former glory was through the retrieval of the AllSpark, which is the premise from which the film series start and progress to its climax.

In the climax of the first film, "Transformers", the AllSpark is destroyed to kill Megatron, rendering the restoration of Cybertron impossible. Optimus Prime declares Earth the new home of the Autobots. Cybertron is not shown as a perfect metallic sphere, but a mountainous husk of a planet with large tree-like spires. A region under Decepticon control had dead Cybertronians shown either hung from them, or left on the "branches" that have been ravaged by war.

In the second film, "", Cybertron was mentioned by Optimus Prime when he told Sam that Earth must not share the same fate as Cybertron: "Whole generations lost". Given these statements and the continuous arrival of both Autobot and Decepticon forces on Earth, it is unclear if Cybertron is even populated by its people at this point.

In the third film, "", Sentinel Prime attempts to use his space bridge pillars to transport Cybertron right next to Earth while simultaneously conquering Earth to use humans as slaves to rebuild it. When the transport is interrupted about halfway through, the transported half of Cybertron collapses in on itself and appears to be destroyed.

Cybertron is never seen or mentioned in the fourth film, "", though the Autobots dealt with Lockdown, who works for the Transformers' creators, possibly indicating that Cybertron was indeed destroyed.

It was later revealed in that Cybertron, while extremely damaged, was still intact enough to remain the base of Quintessa, the creator god of Optimus Prime and all Cybertronians. Quintessa piloted the planet to earth, where she intended to use her magic staff (which was taken by her twelve guardian Knights of Iacon to be given to the human wizard Merlin), to drain the energy of Unicron (revealed to be the core of Earth itself) and thus restore Cybertron. To this end, she commissioned Megatron and brainwashed Optimus Prime into retrieving the staff so that she could destroy the planet. In the battle for the staff, Quintessa used its power to begin pulling the planet's continents back together, with the exoplanet's landmasses scraping away entire continents as it repaired itself. Luckily, Optimus Prime, freed from his brainwashing, managed to help Merlin's descendant, Vivian Wembley and Cade Yeager in stopping Quintessa's plan, saving the Earth and defeating both Megatron and the Cybertronian goddess. Despite stopping the draining of the Earth's energy, enough was siphoned back into Cybertron to allow it to be rendered habitable and life-supporting once more, allowing the Autobots to come home at last. Cybertron and Earth's fate were also forevermore joined in their destinies by this event, and both humans and Autobots began to rebuild their worlds together.

In this universe, the Autobots and Decepticons are political factions and Cybertron is a peaceful planet and is considered a multiversal hub, as well as a gateway in between universes. This Cybertron never had a Great War. In one of the oldest dimensions in the multiverse, one Cybertronian city, Axiom Nexus, is a hub for travelers from other dimensions. According to New Arrivals Coordinator Silverbolt, it is a city "unlike any other in the multiverse". To continue its harmony, all Megatrons, Primes, and "MacGuffins" are considered illegal.

Some travelers arrive here by their own design. Others, however, arrive by accident, and must be processed and given identification bolts. These "offworlders" are seen as inferior throwbacks by many of the proud and technologically advanced TransTechs, and permission to travel outside the borders of Axiom Nexus to the rest of its native Cybertron is granted to a very scant few. As such, its inhabitants have a culture all their own, composed of markets and gangs.

In the "Shattered Glass" universe, Cybertron was a peaceful planet whose inhabitants pursued only science and social harmony until the obsessive researcher Optimus Prime rose from the ranks of civilization and began a civil war. This prompted the mathematician Megaron to lead a resistance to retake Cybertron and restore freedom. This Cybertron never broke free of its orbit and continues to revolve around a sun. True to its backwards universe, Cybertron can a frightening and arbitrary place whose natives are born from the Omega Terminus and possess Embers instead of sparks. Following actions taken by Nexus Prime, this Cybertron manifested an evil incarnation of Primus, who later assumed robot form. This forced the noble inhabitants to depart and colonize a New Cybertron.

In this series, Cybertron (サイバトロン, "Saibatoron") is shown as a large planet that's surface is completely covered with metal. Large towers on the surface of the planet are clearly visible from space. Nothing organic has yet been seen on this planet leading to speculation that it is a machine itself. Back in the Great War, the Autobots managed to drive the Decepticons from Cybertron after throwing the Allspark through a space bridge. It is usually seen in flashbacks. Recently, in Season 3, scenes on Cybertron have been in present times. They include Blurr's arrival on Cybertron after being transwarped from Earth. Another is the Cybertronian high court meeting to discuss Wasp, the accused Decepticon spy. The real spy, being Shockwave, also leaves Ultra Magnus wounded on Cybertron, being found by Ironhide.

This version of Cybertron is depicted as having become a lifeless world by the end of the "War for Cybertron" video game and tie-in novel "Exodus". Primus resides in Cybertron's core and creates life through the Well of All Sparks. However, the Well requires the Allspark to function and with it removed during the Great War to prevent capture by the Decepticons, Cybetron became a barren wasteland. At the end of "", Cybertron is revived when the Autobots use the reconstructed Omega Lock on the underside of the "Nemesis". The series' finale movie, "", focuses on Optimus Prime and Wheeljack on Optimus retrieving the Allspark from space while Unicron uses Megatron's body to attempt to destroy Primus/Cybertron. In the end, Optimus succeeds in defeating Unicron and returns the Allspark to the core, but sacrifices himself in the process.

In the sequel series, "", Cybertron is once again home to a prosperous civilization, though Megatronus attempts to extract the Allspark and merge it with the Anti-Spark to destroy both Earth and Cybetron at the conclusion of the first season. In this continuity, Earth and Cybetron are linked, and since it is discovered that Unicron and Primus reside at their respective cores.

In "", Cybertron is an Energon lacking planet with many buildings and bridges destroyed. There are several locations from the Generation 1 universe include the Decagon and the Iacon Vaults. According to the teaser trailer for "War For Cybertron", Cybertron is a satellite of Alpha Centauri. Several times in the game Transformers will exclaim "Thank Primus!" though he doesn't appear in the game. However the Core of Cybertron, (Isaac C. Singleton, Jr.) may actually be Primus, but is credited simply as "Cybertron" in the game's end credits.

In the Decepticon Campaign, Megatron forces Omega Supreme to open the door to Cybertron's core and travels there with his minions. Upon arrival, Megatron infects the core of Cybertron with dark energon. Cybertron is then shown being fully corrupted by dark energon. In the Autobot Campaign, Optimus is given the task of removing the dark energon from Cybertron's core by the Autobot Council. Optimus and his team first attempt to rescue Omega Supreme from the Decepticons, who is being tortured by dark energon. The Autobots manage to free Omega Supreme and rely on Ratchet to repair Omega Supreme to the point of opening the gateway to Cybertron's core.

During their journey to the core they encounter a corrupted space worm, which later attacks the Autobots when they reach the core. Once the worm is destroyed, Optimus speaks with Cybertron's core. The core informs Optimus that it can repair itself, but it will take several million years, time in which Cybertron will become cold, barren, and lifeless. The core then tells Optimus that if he carries a small piece of the core with him, the core will still survive while it repairs. Optimus accepts the burden and the core relinquishes the Autobot Matrix of Leadership. In "", the Autobots and Decepticons depart Cybertron.

By the time of the "" animated series, the known remaining inhabitants of the planet are a swarm of scraplets – an apparently native 'robotic flesh' eating type of creature – and an Insecticon drone while it continues its attempts at self-repair, though Ratchet hints at the possibility of other Insecticons or possibly even other Autobots having remained behind. It is revealed that eons before the Autobots and Decepticons existed, Cybertron was also inhabited by the Predacons, powerful dragon-like Transformers that became extinct on Cybertron due to an event referred to as "the Great Cataclysm" by Shockwave long before recorded Cybertronian history began. Cybertron's core is stated by Ratchet as being Primus himself during the season one finale. Vector Sigma is also tied into the Matrix of Leadership and Primus, being claimed to be a form of'memory backup' for all who have possessed the Matrix, though the manner in which this is achieved is left unexplained. Jack and Arcee journey to Cybertron in order to use the Key to Vector Sigma to download a copy of Optimus's backup memory. It is unknown if Cybertron has or even retains an atmosphere by this time.

Jack wears a high tech space suit for the trip to prevent any dangers from befalling him, such as lack of oxygen. However Arcee, the scraplets, and the insecticon drone they encounter on the planet seem to have no difficulties surviving on the planet. In later episodes of season two the Autobots find out that Alpha Trion had hidden Omega Keys, artifacts meant to restore Cybertron, to Earth. However, these keys ended up in hands of Starscream who gave them to Megatron in order to restore his place in the Decepticons. When the location of the Omega Lock, a machine meant to channel power to the Keys, was discovered on Cybertron, the Autobots and the Decepticons traveled there and started a battle over the Keys. The Autobots managed to get them all, but when the Decepticons threatened to expose Jack, Miko, and Raf to Cybertron's toxic atmosphere, the Autobots had to hand over the Keys. But when the Decepticons attempted to use the Omega Lock to transform Earth into a metallic planet, Optimus had no choice but to destroy the Omega Lock and leave Cybertron uninhabited forever.

However in the series finale "Deadlock", with Megatron's rebuilding of the Omega lock and his death at Bumblebee's hands, the Autobots are able to use it to reactivate Cybertron, restoring life to their home world. In the television film finale to the series, "Predacons Rising", Cybertron is once again threatened by Unicron, who possesses and enslaves Megaton to eradicate the world. At the same time, Optimus leaves Cybertron for the Theta Scorpia star system to retrieve the Allspark, the key to regenerating new life on Cybertron and Shockwave and Starscream clone Predacons to raise an army against the Autobots. When Unicron arrives, he duels the Autobots and sends them retreating and defeats Predaking, the first Predacon cloned (now rogue), and defeats him, heading for the Predacon burial ground Predaking guarded. Once he arrives, he defeats both of Starscream and Shockwave's Predacons; Skylynx and Darksteel, and proceeds to turn the Predacon corpses into undead Terrorcons so they can assault Cybertron's core at the Well of AllSparks.

In an attempt to stop him, the Autobots team up with Predaking and his brethren (whom he has now taken control of as their king) along with Knockout, who changes from Decepticon to Autobot in order to combat Unicron's legion. The Predacons lead defense of the Well, but are overwhelmed and dragged along as Optimus returns to confront Unicron, eventually tricking him into opening the Allspark's empty container, which sucks his spirit inside, destroying his undead Terrorcons and freeing the Predacons so that they may do away with Starscream, who oppressed and abused them. Freed from his control, Megatron also disbands the Decepticons, having been changed for the better by Unicron's oppression, flying away to start a new life. Optimus, having merged with the Allspark by placing it within the Matrix of Leadership then says a fond farewell to his teammates and flies into Cybertron's core, giving back Cybertron the ability to create life at the cost of his own. As new sparks emerge from the Well to repopulate Cybertron as new transformers, Optimus Prime's spark is seen one last time before it flies away.

After the restoration of the Well of All Sparks, Cybertron once again returned to a period of peace and prosperity. Statues commemorating various figures in the war were constructed. Lieutenant Bumblebee settled into a new life on the planet as a street patrol officer, but eventually returned to Earth via space bridge on the orders of a ghostly Optimus Prime. Cyberton is also ruled by a new Autobot High Council, who placed a bounty on Bumblebee's head for his illegal use of a space bridge and sent Jazz to Earth to respond to the distress signal from the Alchemor. After capturing Ped, Jazz promised he'd smooth things over with the council, but later Drift and Fracture (and their Mini-Cons) arrived on Earth to capture Bumblebee. The High Council also took to blaming Optimus Prime for the war for Cybertron, and effectively banished anyone who spoke out against the injustice, including Ratchet. It was eventually revealed in the third season and the series finale for that the High Council, consisting of Decepticon infiltrators Cyclonus, Cyberewarp, Skyjack, Treadshock, and Riotgear had brainwashed the population of Cybertron into serving them so that they could secretly rebuild the Decepticon Empire. To that end, they commissioned Steeljaw to free Soundwave from the Shadowzone to try to contact Megatron to lead the Decepticon forces while unaware that Megatron had permanently left the Decepticon business to start a new life. They also used a brainwashed invasion force to try and attack Earth, but thanks to the combined efforts of Bumblebee and Optimus' teams on Cybertron and Earth, respectively, the invasion was thwarted and the High Council defeated. Bumblebee's team returned to Earth to serve as Cybertron's first interplanetary ambassadors and protectors on Earth, while Optimus turns down the potential idea of leadership and his team (Ratchet, Jazz, Bulkhead and Windblade) became the new temporary High Council.

Cybertron

Cybertron is a fictional planet, the homeworld of the Transformers in the various fictional incarnations of the metaseries and toyline by Hasbro. In the Japanese series, the planet is referred to as "Cybertron" (first shown on Japanese "Galaxy Force" packaging, although "Cybertron" is the Japanese name for "Autobot") pronounced as Sabertron セイバートロン "Seibātoron". Cybertron is populated by mechanical self-configuring modular lifeforms of variable size who can transform into all kinds of machinery. These are called Cybertronians, or Transformers.

Iacon is the name of the largest city on Cybertron, in the various Transformers media. It is best known as the hometown of Optimus Prime and the Council of Autobot Elders. The city was protected by a great dome, and was the last city-state to fall to the Decepticons, after which the Autobot resistance moved into the tunnels and bases beneath its surface. Iacon appeared throughout the US and UK Transformers comic as the main base of the Autobot resistance on Cybertron.

"And There Shall Come... A Leader", a flashback story in the 1985 UK Annual, shows Iacon as home to the Autobot Council of Elders based in the Celestial Temples, who include Emirate Xaaron, High Councilor Traachon and Councilor Tommandi. The city itself is protected by a great dome, and is the last Autobot outpost to hold out against Megatron's advancing army of Decepticons. During the story, Prime’s troops destroy the main expressways into Iacon, halting the Decepticon advance.

In the 1986 UK Annual, another flashback story, "State Games", details pre-war Cybertron and the buildup to Megatron’s uprising. After the failure of a global ruling body known as the Overlords, Cybertron has been divided into various independent city-states, all of which are now facing overcrowding and a lack of resources. Iacon is the largest and wealthiest of these city-states, and the home of Optimus Prime. Inter-state gladiator matches increase the tension between Iacon and lesser city-states such as Tarn and Vos, and eventually a botched act of sabotage leads Tarn and Vos into civil war with each other. The survivors are united by Megatron, and blame Iacon for standing by and, falsely, starting the conflict in the first place.

In the storyline (UK #66 to #88), Iacon is revealed to have been conquered by the Decepticons and its dome is a broken shell. Emirate Xaaron now leads the Autobot resistance movement from secret bases beneath Iacon’s surface.

The Autobot resistance moves out of Iacon and into the city-state of Kalis in the "City of Fear" storyline (UK #164 to #169), but are back in Iacon by "Yesterday’s Heroes" (UK #252 to #254, US #60). Whether Iacon survives Unicron's attack in "On the Edge of Extinction" (UK #319 to #322, US #75) is not made explicit.
Cybertron is described in the first issue of the Marvel comic book as being the size of Saturn, which would logically mean it possessed incredibly dense gravity, and yet it did not, possibly as a result of its hollow structure, honeycombed as it is by tunnels. However, in later depictions the art suggests Cybertron is much smaller, particularly during the attack by Unicron (detailed in "On the Edge of Extinction" in UK #319 to #322, US #75), where the scale differences between humans, individual Transformers and the ‘planet-sized’ Unicron suggest Cybertron to be closer in size to the earth's moon, as depicted in the cartoon continuity.

Cybertron has a metallic surface, although whether this extends to the core is debatable: in "The Legacy of Unicron" (UK #146 to #151) and later in "Primal Scream" (UK #259 to 261, US #61) it is revealed to have originally been ‘space junk’, the composition of which is unknown. The atmosphere is breathable by carbon-based life, but liquid water is rare enough on the planet that its existence is in doubt. Cybertron previously orbited Alpha Centauri, but was later thrown out of orbit and sent wandering through the galaxy.

Knowing nothing of their true origins or the destiny they were to fulfill, the Transformers eventually splintered into two factions – the politically dissident Decepticons, who waged war on the peaceful Autobots. Megatron, leader of the Decepticons, schemed to turn Cybertron into the ultimate weapon, a warworld that would wreak havoc across the galaxy, and the resulting war knocked Cybertron out of its orbit and set it adrift in the universe. Around four million years BC, Cybertron's path brought it into the Sol system, heading directly for the asteroid belt, which threatened to heavily damage the planet. Autobot leader Optimus Prime led a contingent of his warriors aboard the Ark to destroy the rocks in Cybertron's path, but once they had succeeded, they were attacked by the Decepticons, causing all involved to be trapped in stasis on prehistoric Earth.

While the Autobots and Decepticons aboard the Ark were trapped in stasis, life on Cybertron continued. Consequently, the young warlord Trannis took control of the Decepticon army on the planet, and led a fierce campaign against the Autobots, reclaiming the cities they had taken, levelling the capital city-state of Iacon, and executing the Autobot council of elders, save for Emirate Xaaron, who fled with his troops and continued to fight. Xaaron formed an elite Autobot strike team, the Wreckers, who succeeded in assassinating Trannis, only to have the conflict escalate when the even more dangerous Lord Straxus took his place, forcing Xaaron and his men into hiding, fighting a guerilla war from a number of "Autobases" across the planet, headed up by Fortress Maximus and Perceptor, among others. Maximus's team, however, soon abandoned Cybertron, tiring of war and seeking peace on the planet Nebulos.

When the Transformers stranded on Earth were reactivated in 1984, the Decepticons succeeded in getting a message to Cybertron, and Straxus responded by arranging for the construction of a space bridge between the worlds. In a confrontation with Blaster aboard the bridge, Straxus's body was destroyed, leaving him a severed head, which in turn forced him to attempt the mental possession of Megatron's body. Megatron did not take kindly to this, and retaliated by destroying Straxus, leaving the Decepticon fuel auditor, Ratbat, as Cybertron's local Decepticon commander.

Little of import occurred on Cybertron in the immediate future as, more and more, the war spilled over to Earth, with the Autobot and Decepticon commanders summoning more and more warriors to the planet. Ratbat's death in the Underbase affair allowed a triumvirate of three Decepticons – Siezer, Legonis and Octus – to established themselves as rulers on Cybertron while Scorponok led on Earth, but following their destruction by Megatron, and his own subsequent disappearance, their appointed replacement, Thunderwing, took control and dispatched the Mayhem Attack Squad to track down the Autobot Pretenders. When the ensuing battle resulted in the malfunction of a teleportation portal, Grimlock, Bumblebee and Jazz found themselves at the core of Cybertron, bearing witness to the visage of Primus, and learned of his legend from the ancient "Keeper". The Keeper was then struck down by the Mayhems, and the battle that followed briefly awakened Primus, who unleashed a single scream that was heard on the fringes of known space... by Unicron.

As Unicron bore down on the planet, he sent an agent, Galvatron, ahead to sow terror in his name. But Galvatron chafed in Unicron's service and instead awoke Primus, who possessed Emirate Xaaron and teleported every Transformer back to Cybertron in order to unite them, as Unicron attacked the planet. Although Optimus Prime was able to use the Creation Matrix to destroy Unicron, it seemed that Cybertron was to meet its end by other means - tremors and storms began to pervade the planet, which seemed to be tearing itself apart, forcing the remaining Autobots and Decepticons to flee. In actuality, however, the final wave of Matrix energy released in Unicron's destruction had begun a planet-wide rebirth, which was then guided to conclusion by the Last Autobot, restoring and regenerating Cybertron, which the Autobots then occupied.

The above is the story of Primus as related in the United States in Marvel Comics but the story was originally told in British comics. The Primus story is recounted three times under Simon Furman - in order: Transformers UK #150, Transformers US #61, and US #74, and while the Primus/Unicron battle and ultimate solution are always the same, the background to their fight differs in each telling.

The first (told by Unicron) has Primus and Unicron leading armies of similar beings at the dawn of the universe. The second (told by the Primus Chamber's Keeper) had the two as the last of their respective pantheons and Primus needing to stop Unicron before he could pass on from this realm. The third, told by Primus, has Unicron destroying the previous universe and trying to end the current one, with Primus being formed by the "sentient core" of this universe to stop him.

By the third re-telling, the idea that Unicron and Primus were related to similar entities had been dropped and was not picked up again.

In the sequel series to the original "Transformers" comics, more of the history of Cybertron and the Transformer race was revealed, as Optimus Prime discovered that they had once possessed the ability to asexually reproduce by "budding". This was an ability that ceased to function and was forgotten as part of Primus's design, but a group of Cybertronians discovered it and unlocked it within themselves. They continued to multiply beyond the intended limits of their race, diluting their essences until all that remained were single minded killers arrogant in their own supposed superiority - and The Swarm, a dark, destructive byproduct of the reproduction which ventured into space and destroyed other worlds and races, just as these "second generation" Cybertronians left Cybertron under the command of Jhiaxus, and began colonising other planets. When the Swarm returned with the intention of consuming Cybertron, the world of its origin, Optimus Prime used the Matrix to purify it.

In the TV series, Cybertron is a planet once used by the Quintessons as a factory with assembly lines creating soldier ("military hardware") and worker ("consumer goods") robots. (Note: This seems to contradict material presented in the first two seasons of the series. The whole series is full of apparent contradictions and inconsistencies.) Following a rebellion which drove the Quintessons off the planet, the workers became the Autobots and the soldiers became the Decepticons. These two factions eventually engaged in civil war, which forms the basis of the various "Transformers" stories. Some time between the Quintesson occupation and the Autobot/Decepticon war, Cybertron entered a "golden age", with the planet becoming an actual gold color. The energy demands of the war eventually returned Cybertron to its original coloration.

In the first episode, "More Than Meets the Eye Part 1", the dome structure of Iacon retracts to reveal a launching pad for the Autobot spacecraft the Ark. After Autobot leader Optimus Prime and Decepticon leader Megatron journeyed to Earth, crash landing four million years ago and entering emergency stasis lock, Shockwave keeps the planet in stalemate until Megatron awakens in 1984. Cybertron's point of origin within the galaxy was never revealed in the original cartoon, but originally required a dimensional space bridge in order to return to the planet from Earth. Later stories depicted the ability to travel to Cybertron via the use of three interstellar Transformers; Skyfire, Astrotrain, and Omega Supreme. During the first two seasons of the original cartoon, Cybertron was brought into the solar system, and twice was close enough to Earth to be seen by the naked human eye.

Travel between Earth and Cybertron became roughly a half a day's journey, as depicted in the 1986 feature film "". The Decepticons have conquered the planet by 2005, and Cybertron is seen to have at least three moons, two of which are consumed by Unicron. In the aftermath of Unicron's attack on Cybertron, and subsequent defeat, the Autobots are able to reclaim the planet, forcing the Decepticons to retreat to Chaar, a blackened husk of a world. In the final part of "The Rebirth", Vector Sigma absorbed the energies of a near-supernova sun, energizing Cybertron and bringing about a new Golden Age. Unicron's head became an artificial satellite for much of the third season, after his body was destroyed and was reactivated at during the episode "Ghost in the Machine", though it appears to have gone dormant again afterwards. It is unknown what became of Unicron's head when Cybertron was moved into near-Earth orbit during the "Rebirth" episodes, but by the time of "Beast Wars" it is shown that it no longer orbits the planet.

While the American "Transformers" series was concluded with the three-part miniseries, "The Rebirth" (set in 2007), in Japan it was opted to continue the series, and so "The Rebirth" was disregarded in favour of producing "Transformers: Headmasters", a full-length 35-episode series set in the year 2011.

In 2011, it was discovered that the release of the energy of the Matrix by Optimus Prime to cure the Hate Plague had much more far-reaching consequences that anyone suspected. With the Matrix's energy depleted, Vector Sigma's balance – previously tilted in favour of the Autobots by the existence of the Matrix – was reset to neutrality, allowing the Decepticons, bolstered by their new Headmaster troops, to freely invade Cybertron "(known as Seibertron in Japan)". Eventually, this forced Optimus Prime to sacrifice his life by merging with Vector Sigma in order to stabilise the computer before it destroyed Cybertron from within.

Not long thereafter, Vector Sigma developed a new metal alloy dubbed Cybertonuron, which enticed Galvatron into another raid on the planet. However, the Decepticon Headmaster leader, Zarak feared the power that Galvatron would gain from the alloy. To prevent either him or the Autobots from obtaining it, Zarak arranged for his Headmasters to plant bombs at the core of the planet; Vector Sigma's chamber. The Autobots were unable to stop the countdown and the bombs detonating, tearing Cybertron apart and leaving it a charred uninhabitable ruin drifting in space.

Dorling Kindersley's "Transformers: The Ultimate Guide" included illustrations and descriptions of Cybetron’s surface, including an image of Iacon itself. The Guide, first published in 2004, drew on both the Marvel comic continuity and the then recent depictions of Cybertron and Iacon from the Dreamwave "" comic book series. This included elements such as the Stellar Galleries from the latter series, not documented in the original Marvel run. It also depicted Cybertron in a fully realized 'robot mode' as Primus, something never even hinted as a possibility before in the original toyline or comics by Marvel, but which became a reality in, which was the first television series to not only depict Cybertron as having the same transforming capability as Unicron, but also showing it occurring within the show.

In the IDW comics, Cybertron orbits Lambda Scorpii and has been rendered mostly uninhabitable by the war. While Transformers can survive on the surface, they cannot live there indefinitely.

Cybertron's robot mode, Primus was never seen or mentioned in the original U.S. Transformers television series, the writers of "Beast Wars" included Primus to the television mythos with mention of Primus by the Transformers in that series, and the creation of the Covenant of Primus in the series finale.

The expanded fiction of the Botcon and OTFCC comic books suggest that Primus experimented with a small planet before actually transforming himself into Cybertron. This world, named Protos, was where he created the first 12 Transformers, each of them themed after an animal of the zodiac. Later, Primus created the Original Thirteen Transformers.

Primus appeared with Alpha Trion in the "Transformers: Universe" comic, bringing back Optimus Primal and guiding him in his battles against Unicron allied Decepticons.

Cybertron's governing structure during the Beast Wars era is based upon the Pax Cybertronia (Peace of Cybertron). The peace on Cybertron is maintained through a treaty known as the Pax Cybertronia, which – perhaps unfairly – ranks the Predacons as second-class citizens, with the Maximals in control of the planet. Each side is governed by a council;the Maximals governing body is known as the Maximal Imperium while the Predacons' version, the Tripredacus Council, operate out of a satellite orbiting the planet or star, quietly working to their own agenda... an agenda that was sorely disrupted by the rise to power of the renegade, Megatron, who stole a ship and escaped to prehistoric Earth with the intent of altering time.

There are many distinct areas of Cybertron. Ranging from locations on the surface, to any of the number of buried ruins. In "The Reformatting", the first episode of the "Beast Machines" TV show, the Maximals discover the remains of Iacon on Cybertron, deep beneath the planets current surface. The episode suggests that in the intervening years between the end of the G1 / G2 series and the start of "Beast Wars", the inhabitants of Cybertron have built over older city-states with new cities, in a similar manner to an onion skin.

As alluded to in Beast Wars, there is a giant amusement park near the northern pole of the planet. Orbiting Cybertron are a number of structures, such as starports and bases. The Tripredicus Council is established on one of these orbiting bases. There are also a number of communication satellites.

Beneath the cityscape surface of the planet lies layer upon layer of earlier civilizations. One entire Autobot era city lies just beneath the surface. Beneath this city lies ruins of older Cybertronian civilizations, all ending in the rocky core of the planet. It is here that the Oracle of Vector Sigma lies. It is also here that the techno-organic core can be accessed.

In the two groups' absence, Cybertronians had undergone another modification called the "Quantum Cycle Upgrade", in which they were individually fitted with alternate mode scanners so they would not have to rely on external mechanisms to do the job for them. Striking fast and hard, Megatron unleashed a transformation-freezing virus on the populous and deployed a small army of "Vehicon" drones, who extracted the sparks of the virus's hapless victims. Their shells were then used to create more Vehicons, and so it continued until the entire population of Cybertron had their sparks removed, and all that remained were the Vehicons, united under the singular, guiding intelligence of Megatron, who, for all intents and purpose, was now Cybertron itself.

The "" version of Cybertron is never seen (save for once in a flashback in "Ultra Magnus" and "Ultra Magnus: Forced Fusion"). The entirety of the series takes place on Earth. It is unknown what cities, or Autobots and Predacons that could be there, but it is presumably a still living planet. Whether or not it is Primus is unknown. Primus was not mentioned at all, nor Unicron, but Vector Sigma and Alpha Trion exist, as well as the All Spark.

The little information on Cybertron established in the series is that Cybertron was located near or orbiting a larger ringed world, and had an asteroid prison colony in which dangerous Decepticon and Predacon prisoners were interred. At one point there were a series of civil wars, in which Optimus Prime and Ultra Magnus, both creations of Alpha Trion, fought side-by-side. Following the wars, Magnus was honored, but Vector Sigma selected Optimus as Autobot leader and bestowed on him the Matrix of Leadership. The Predacons on Cybertron were ruled over by a council, of which Megatron was a subordinate, though he once claimed to be "leader of the Predacons and future ruler of the galaxy" and that he was already "ruler of many worlds".

Cybertron is the home planet of the Transformers in the three television series, "", "" and "". In the miniseries, Cybertron, Primus' material body, is inhabited by Mini-Cons as well as Autobots and Decepticons, who are unaware the Mini-Cons were weapons forged by Unicron. The war between the Autobots and Decepticons is escalated by Megatron's attempt to gather them. During the escalation, the Mini-Cons liberate themselves and leave the planet in a mass exodus, leading to a four million years (one million years in the Dreamwave comic) stalemate between the two principal forces. Ten years of peace follow "Armada" (2002–2004) and then "Energon" (2014). After "Cybertron"'s climax, the planet has an atmosphere more suitable for humans and organic wildlife.

Long ago, Cybertron was peaceful, until the evil Decepticons waged war against the Autobots. Both sides fought for control of the planet, each ruling one half. Eventually, a mysterious, unclarified "cataclysm" struck the planet, following which the small race of robots known as the Mini-Cons emerged. It would later be discovered that the Mini-Cons were creations of Unicron – currently orbiting Cybertron in a weakened state, disguised as a moon – who had implanted his cells within Cybertron, where they grew and hatched into the Mini-Cons; presumably, then, the cataclysm was caused by Unicron's implantation of his cells. The larger Transformers on Cybertron soon discovered that the Mini-Cons possessed power-enhancing abilities, and began to war over the small robots (it is unclear if the Autobots and Decepticons were already at war, or if it was the emergence of the Mini-Cons which began the conflict).

Through a complicated instance of time-travel, however, the Mini-Cons had the seeds of souls and sentience planted within them at the moment of their creation by a group of time-displaced human children, and as they came to think and feel for themselves, they sought to fulfill their own destiny, by going to Earth to find the humans. The Autobots agreed to aid the Mini-Cons, preferring that they be free and not subject to anyone's will, but the Decepticons still sought to control them, and attacked the launch of the Mini-Con ship, which was crippled as it escaped through a portal, causing it to crash-land on Earth, where the Mini-Cons remained dormant for a million years until they were awakened by the very humans they had come to find. The signal released by their awakening brought the Transformers on Cybertron to Earth in pursuit of them.

As part of the rebuilding program, the Autobot-Decepticon alliance entered into a partnership with Earth's governments to mine Earth and the Sol system for the energy-rich mineral known as Energon. Over the next ten years, Cybertron was steadily restored as "Cybertron Cities" were built in strategic positions on Earth, its moon and Mars to gather Energon and keep the planet rich and healthy.

Following Megatron's resurrection through the power of Energon, he began a quest to restore Unicron to life, under his control, which eventually led him to move the planet-eater's body through a spacebridge into the vicinity of Cybertron itself. After a series of attacks on the planet, during which Primus's chamber was penetrated by Terrorcons, a reaction between the negatively charged Energon within Unicron's body, and the positive Energon used by the Autobots caused a rupture in space, leading to a new sector of the universe where the planets consumed by Unicron had been recreated. A series of battles followed which eventually resulted in Unicron's restoration and destruction, save for his consciousness, which continued to exist within Megatron.

Guided by Unicron, Megatron gathered the remnants of his army and attacked Cybertron once more, using the destruction as a cover for his true motive – to acquire the power of the Super Energon, which transformed into Galvatron. With the aid of Sixshot, the Decepticons were then able to seize control of Cybertron's computer systems, enshrouding the surface of the planet in a poisonous Energon gas that kept the Autobots at a distance while the Energon Towers were used to propel Cybertron through the spatial rift, into the new region of space. Its motion slowed by a giant-sized, Primus-empowered Optimus Supreme, Cybertron was liberated from the Decepticons when Galvatron turned his attention away from it, using the Super-Energon to grow to colossal size himself and departing the world, heading out to find Unicron's spark, drifting in space.

When Galvatron was subsequently possessed by Unicron's spark, Primus used the Super Energon to create a foundling sun, into which Galvatron plunged himself, preferring to perish than to allow himself to be controlled. But, while appearing to be the end of Unicron's threat, in truth, it was the beginning of a much greater danger...

Primus's plan to contain Unicron's spark within the Energon sun was doomed to failure – close to a decade later, the sun collapsed in on itself, turning into a gigantic black hole which threatened not merely Cybertron, the fabric of reality and the multiverse itself, causing ripples throughout space and time that disrupted history, causing inconsistencies between the "Cybertron" animated series and its predecessors. Many Transformers were forced to depart for Earth while the Autobots search for the Cyber Planet Keys to save their world. Over time, it would turn out Cybertron was a dormant Primus. After the destruction of the black hole, Primus turned back into Cybertron with cities, atmosphere for humans, roads and wildlife.

In 2006, a toy of Cybertron was released as part of the toy line. The toy transformed from planet mode into Primus, the Transformers creator. Of the many cities sculpted into the toys surface, one, painted in gold, clearly resembles the illustration of Iacon from "The Ultimate Guide".According to "" comic book by IDW Publishing, Optimus Prime and Megatron co-ruled Cybertron. The Allspark is responsible for giving life to the Transformers. When Megatron begins a war to control it for himself, Optimus sends it into the depths of outer space in the hope that he can defeat him quickly. The war drags on, and Optimus sends Bumblebee to retrieve it, because its absence will cause the planet to shut down. It would later be revealed in the third film that Sentinel Prime was the Autobot leader when the war began and was seemingly killed as he attempted to flee Cyberton with a super weapon. Optimus then took over full command, with the rest of the events likely playing out the same way.

Cybertron's upper layers seem to have a lot of interlocking hexagonal shapes, and several battles near the end of the war took place there. Sentinel Prime used these geographical features to his advantage when he attempted to escape Cybertron aboard the "Ark". Later on, Sentinel Prime attempted to teleport Cybertron via the space bridge-forming pillars from his ship, the Ark in order to acquire Earth's resources to re-energize Cybertron. However, Bumblebee destroyed the master pillar and Cybertron collapsed as it was going through, presumably destroying Cybertron forever.

Geography-wise, the surface of Cybertron is a mystery. Large rivers of liquid criss-cross the planet, though whether this is lava, molten metal, or possibly energon is anyone's guess. In more urbanized areas, such as the city of Tyger Pax, the stone and lava seem to be covered over with steel or other refined metal. However, these incidents took place during the war, so it may have been the result of the devastation Cybertron saw. This liquid is even on the tops of buildings. Internally, Cybertron has similar features to the inside of a "Transformer", including gyroscopic joints. While everyone had abandoned Cybertron, the twin Autobot Skids and Mudflap hung out there for a while, and Starscream began organising an army there in secret. The location on Cybertron that is named after Primus is surrounded by the Rad Zone and Uraya.

Eventually, what little the Transformers knew of their origins would be lost to time. A new society arose, known as the Autobots. The Autobots were a peaceful people, led by Optimus Prime, head of the Science Division, and Protector Megatron, head of the Defense Force. The two leaders created a balance; Optimus was fair while Megatron was firm. Their world's main cities included Tyger Pax, Metrotitan, Simfur, and the capital city of Trypticon. Another area of importance was Burthov, where the Science Division had many facilities. In time, the Autobots began work on a dig near the Simfur Temple, discovering the remains of the Twelve's sarcophagi and the intact sarcophagus of The Fallen. At the same time, unknown alien hostiles attacked Cybertron. Megatron had Optimus remove the intact artifact to his quarters to better protect it, allowing him to come under the influence of The Fallen.

As Megatron began to grow more aggressive, Optimus discovered that he was the orphaned Prime hidden away when the Dynasty fell. Megatron raised an army, the Decepticons, and sought to take the AllSpark to conquer the universe. However, most of the early Decepticon forces left on the "Nemesis" with The Fallen and Soundwave to seek out the harvester. With the number of Megatron's Decepticons now diminished, Optimus assumed his proper title and raised his own army of Autobots. In the war that followed, Cybertron was decimated. Prime eventually sent the AllSpark through a wormhole into deep space, and Megatron pursued it. Both were lost. Without the AllSpark's power, Cybertron became a dead world. The Autobots and the Decepticons scattered across the galaxy, hoping either to create a new world or locate the AllSpark and restore Cybertron. A number of Transformers remained, with the Decepticons centered in Trypticon (now a "Decepticon" capital), but this didn't last long.

Note: Information in "italics" occur in the alternate storyline where Megatron won the battle for the Allspark.

"Cybertron's status was unknown, with everyone abandoning it as it began to die. However, Stockade and a group of Decepticons remained, staying alive by using Nucleon. Stockade believed they could renew Cybertron by summoning a new power source, one related to the AllSpark. They succeeded in summoning such an energy being, which did enter Cybertron to renew it and to everyone's horror, announced itself as Unicron, the Anti-Life! "

"The possessed Cybertron was swiftly altered into a scarier-looking form with a large mouth and grasping prongs, turned hostile to those on it, and warped to the Sol system. The Autobots and Decepticons were able to destroy Unicron, but Cybertron was left in its transformed state and seemingly in the Sol system, as well as continuing to be dead and powerless."

"When the Autobots were ordered off American soil, they regrouped "under" Cybertron and began working on the teleportation engines that Unicron had left there when he transformed the planet. Using these, they were able to make a decisive strike by teleporting the entire Decepticon army to Cybertron, then teleporting "Cybertron" to the far reaches of space. With the engines now burnt out and no energy on the planet, the Decepticons were marooned there, at the cost of the Autobots never being able to go home."

In the early-21st century live-action film trilogy directed by Michael Bay, Cybertron is depicted much in the same way as in the source material: the homeplanet of the Transformer race. As described in the first film, the AllSpark is the origin of life in Cybertron, and over millennia, its population grew and developed a global state, peaceful and just, remaining so for eons until the war for possession of the AllSpark broke out. The war was so devastating that it ravaged the planet until it was consumed by death, and the only way to restore Cybertron to its former glory was through the retrieval of the AllSpark, which is the premise from which the film series start and progress to its climax.

In the climax of the first film, "Transformers", the AllSpark is destroyed to kill Megatron, rendering the restoration of Cybertron impossible. Optimus Prime declares Earth the new home of the Autobots. Cybertron is not shown as a perfect metallic sphere, but a mountainous husk of a planet with large tree-like spires. A region under Decepticon control had dead Cybertronians shown either hung from them, or left on the "branches" that have been ravaged by war.

In the second film, "", Cybertron was mentioned by Optimus Prime when he told Sam that Earth must not share the same fate as Cybertron: "Whole generations lost". Given these statements and the continuous arrival of both Autobot and Decepticon forces on Earth, it is unclear if Cybertron is even populated by its people at this point.

In the third film, "", Sentinel Prime attempts to use his space bridge pillars to transport Cybertron right next to Earth while simultaneously conquering Earth to use humans as slaves to rebuild it. When the transport is interrupted about halfway through, the transported half of Cybertron collapses in on itself and appears to be destroyed.

Cybertron is never seen or mentioned in the fourth film, "", though the Autobots dealt with Lockdown, who works for the Transformers' creators, possibly indicating that Cybertron was indeed destroyed.

In this universe, the Autobots and Decepticons are political factions and Cybertron is a peaceful planet and is considered a multiversal hub, as well as a gateway in between universes. This Cybertron never had a Great War. In one of the oldest dimensions in the multiverse, one Cybertronian city, Axiom Nexus, is a hub for travelers from other dimensions. According to New Arrivals Coordinator Silverbolt, it is a city "unlike any other in the multiverse". To continue its harmony, all Megatrons, Primes, and "MacGuffins" are considered illegal.

Some travelers arrive here by their own design. Others, however, arrive by accident, and must be processed and given identification bolts. These "offworlders" are seen as inferior throwbacks by many of the proud and technologically advanced TransTechs, and permission to travel outside the borders of Axiom Nexus to the rest of its native Cybertron is granted to a very scant few. As such, its inhabitants have a culture all their own, composed of markets and gangs.

In the "Shattered Glass" universe, Cybertron was a peaceful planet whose inhabitants pursued only science and social harmony until the obsessive researcher Optimus Prime rose from the ranks of civilization and began a civil war. This prompted the mathematician Megaron to lead a resistance to retake Cybertron and restore freedom. This Cybertron never broke free of its orbit and continues to revolve around a sun. True to its backwards universe, Cybertron can a frightening and arbitrary place whose natives are born from the Omega Terminus and possess Embers instead of sparks. Following actions taken by Nexus Prime, this Cybertron manifested an evil incarnation of Primus, who later assumed robot form. This forced the noble inhabitants to depart and colonize a New Cybertron.

In this series, Cybertron (サイバトロン, "Saibatoron") is shown as a large planet that's surface is completely covered with metal. Large towers on the surface of the planet are clearly visible from space. Nothing organic has yet been seen on this planet leading to speculation that it is a machine itself. Back in the Great War, the Autobots managed to drive the Decepticons from Cybertron after throwing the Allspark through a space bridge. It is usually seen in flashbacks. Recently, in Season 3, scenes on Cybertron have been in present times. They include Blurr's arrival on Cybertron after being transwarped from Earth. Another is the Cybertronian high court meeting to discuss Wasp, the accused Decepticon spy. The real spy, being Shockwave, also leaves Ultra Magnus wounded on Cybertron, being found by Ironhide.

This version of Cybertron is depicted as having become a lifeless world by the end of the "War for Cybertron" video game and tie-in novel "Exodus". Primus resides in Cybertron's core and creates life through the Well of All Sparks. However, the Well requires the Allspark to function and with it removed during the Great War to prevent capture by the Decepticons, Cybetron became a barren wasteland. At the end of "", Cybertron is revived when the Autobots use the reconstructed Omega Lock on the underside of the "Nemesis". The series' finale movie, "", focuses on Optimus Prime and Wheeljack on Optimus retrieving the Allspark from space while Unicron uses Megatron's body to attempt to destroy Primus/Cybertron. In the end, Optimus succeeds in defeating Unicron and returns the Allspark to the core, but sacrifices himself in the process.

In the sequel series, "", Cybertron is once again home to a prosperous civilization, though Megatronus attempts to extract the Allspark and merge it with the Anti-Spark to destroy both Earth and Cybetron at the conclusion of the first season. In this continuity, Earth and Cybetron are linked, and since it is discovered that Unicron and Primus reside at their respective cores.

In "", Cybertron is an Energon lacking planet with many buildings and bridges destroyed. There are several locations from the Generation 1 universe include the Decagon and the Iacon Vaults. According to the teaser trailer for "War For Cybertron", Cybertron is a satellite of Alpha Centauri. Several times in the game Transformers will exclaim "Thank Primus!" though he doesn't appear in the game. However the Core of Cybertron, (Isaac C. Singleton, Jr.) may actually be Primus, but is credited simply as "Cybertron" in the game's end credits.

In the Decepticon Campaign, Megatron forces Omega Supreme to open the door to Cybertron's core and travels there with his minions. Upon arrival, Megatron infects the core of Cybertron with dark energon. Cybertron is then shown being fully corrupted by dark energon. In the Autobot Campaign, Optimus is given the task of removing the dark energon from Cybertron's core by the Autobot Council. Optimus and his team first attempt to rescue Omega Supreme from the Decepticons, who is being tortured by dark energon. The Autobots manage to free Omega Supreme and rely on Ratchet to repair Omega Supreme to the point of opening the gateway to Cybertron's core.

During their journey to the core they encounter a corrupted space worm, which later attacks the Autobots when they reach the core. Once the worm is destroyed, Optimus speaks with Cybertron's core. The core informs Optimus that it can repair itself, but it will take several million years, time in which Cybertron will become cold, barren, and lifeless. The core then tells Optimus that if he carries a small piece of the core with him, the core will still survive while it repairs. Optimus accepts the burden and the core relinquishes the Autobot Matrix of Leadership. In "", the Autobots and Decepticons depart Cybertron.

However in the series finale "Deadlock", with Megatron's rebuilding of the Omega lock and his death at Bumblebee's hands, the Autobots are able to use it to reactivate Cybertron, restoring life to their home world. In the television film finale to the series, "Predacons Rising", Cybertron is once again threatened by Unicron, who possesses and enslaves Megaton to eradicate the world. At the same time, Optimus leaves Cybertron for the Theta Scorpia star system to retrieve the Allspark, the key to regenerating new life on Cybertron and Shockwave and Starscream clone Predacons to raise an army against the Autobots. When Unicron arrives, he duels the Autobots and sends them retreating and defeats Predaking, the first Predacon cloned (now rogue), and defeats him, heading for the Predacon burial ground Predaking guarded. Once he arrives, he defeats both of Starscream and Shockwave's Predacons; Skylynx and Darksteel, and proceeds to turn the Predacon corpses into undead Terrorcons so they can assault Cybertron's core at the Well of AllSparks.

The expanded fiction of the Botcon and OTFCC comic books suggest that Primus experimented with a small planet before actually transforming himself into Cybertron. This world, named Protos, was where he created the first 12 Transformers, each of them themed after an animal of the zodiac. Later, Primus created the Original Thirteen Transformers.

Cybertron

Cybertron is a fictional planet, the homeworld of the Transformers in the various fictional incarnations of the metaseries and toyline by Hasbro. In the Japanese series, the planet is referred to as "Cybertron" (first shown on Japanese "Galaxy Force" packaging, although "Cybertron" is the Japanese name for "Autobot") pronounced as Sabertron セイバートロン "Seibātoron". Cybertron is populated by mechanical self-configuring modular lifeforms of variable size who can transform into all kinds of machinery. These are called Cybertronians, or Transformers.

Iacon is the name of the largest city on Cybertron, in the various Transformers media. It is best known as the hometown of Optimus Prime and the Council of Autobot Elders. The city was protected by a great dome, and was the last city-state to fall to the Decepticons, after which the Autobot resistance moved into the tunnels and bases beneath its surface. Iacon appeared throughout the US and UK Transformers comic as the main base of the Autobot resistance on Cybertron.

"And There Shall Come... A Leader", a flashback story in the 1985 UK Annual, shows Iacon as home to the Autobot Council of Elders based in the Celestial Temples, who include Emirate Xaaron, High Councilor Traachon and Councilor Tommandi. The city itself is protected by a great dome, and is the last Autobot outpost to hold out against Megatron's advancing army of Decepticons. During the story, Prime’s troops destroy the main expressways into Iacon, halting the Decepticon advance.

In the 1986 UK Annual, another flashback story, "State Games", details pre-war Cybertron and the buildup to Megatron’s uprising. After the failure of a global ruling body known as the Overlords, Cybertron has been divided into various independent city-states, all of which are now facing overcrowding and a lack of resources. Iacon is the largest and wealthiest of these city-states, and the home of Optimus Prime. Inter-state gladiator matches increase the tension between Iacon and lesser city-states such as Tarn and Vos, and eventually a botched act of sabotage leads Tarn and Vos into civil war with each other. The survivors are united by Megatron, and blame Iacon for standing by and, falsely, starting the conflict in the first place.

In the storyline (UK #66 to #88), Iacon is revealed to have been conquered by the Decepticons and its dome is a broken shell. Emirate Xaaron now leads the Autobot resistance movement from secret bases beneath Iacon’s surface.

The Autobot resistance moves out of Iacon and into the city-state of Kalis in the "City of Fear" storyline (UK #164 to #169), but are back in Iacon by "Yesterday’s Heroes" (UK #252 to #254, US #60). Whether Iacon survives Unicron's attack in "On the Edge of Extinction" (UK #319 to #322, US #75) is not made explicit.
Cybertron is described in the first issue of the Marvel comic book as being the size of Saturn, which would logically mean it possessed incredibly dense gravity, and yet it did not, possibly as a result of its hollow structure, honeycombed as it is by tunnels. However, in later depictions the art suggests Cybertron is much smaller, particularly during the attack by Unicron (detailed in "On the Edge of Extinction" in UK #319 to #322, US #75), where the scale differences between humans, individual Transformers and the ‘planet-sized’ Unicron suggest Cybertron to be closer in size to the earth's moon, as depicted in the cartoon continuity.

Cybertron has a metallic surface, although whether this extends to the core is debatable: in "The Legacy of Unicron" (UK #146 to #151) and later in "Primal Scream" (UK #259 to 261, US #61) it is revealed to have originally been ‘space junk’, the composition of which is unknown. The atmosphere is breathable by carbon-based life, but liquid water is rare enough on the planet that its existence is in doubt. Cybertron previously orbited Alpha Centauri, but was later thrown out of orbit and sent wandering through the galaxy.

Knowing nothing of their true origins or the destiny they were to fulfill, the Transformers eventually splintered into two factions – the politically dissident Decepticons, who waged war on the peaceful Autobots. Megatron, leader of the Decepticons, schemed to turn Cybertron into the ultimate weapon, a warworld that would wreak havoc across the galaxy, and the resulting war knocked Cybertron out of its orbit and set it adrift in the universe. Around four million years BC, Cybertron's path brought it into the Sol system, heading directly for the asteroid belt, which threatened to heavily damage the planet. Autobot leader Optimus Prime led a contingent of his warriors aboard the Ark to destroy the rocks in Cybertron's path, but once they had succeeded, they were attacked by the Decepticons, causing all involved to be trapped in stasis on prehistoric Earth.

While the Autobots and Decepticons aboard the Ark were trapped in stasis, life on Cybertron continued. Consequently, the young warlord Trannis took control of the Decepticon army on the planet, and led a fierce campaign against the Autobots, reclaiming the cities they had taken, levelling the capital city-state of Iacon, and executing the Autobot council of elders, save for Emirate Xaaron, who fled with his troops and continued to fight. Xaaron formed an elite Autobot strike team, the Wreckers, who succeeded in assassinating Trannis, only to have the conflict escalate when the even more dangerous Lord Straxus took his place, forcing Xaaron and his men into hiding, fighting a guerilla war from a number of "Autobases" across the planet, headed up by Fortress Maximus and Perceptor, among others. Maximus's team, however, soon abandoned Cybertron, tiring of war and seeking peace on the planet Nebulos.

When the Transformers stranded on Earth were reactivated in 1984, the Decepticons succeeded in getting a message to Cybertron, and Straxus responded by arranging for the construction of a space bridge between the worlds. In a confrontation with Blaster aboard the bridge, Straxus's body was destroyed, leaving him a severed head, which in turn forced him to attempt the mental possession of Megatron's body. Megatron did not take kindly to this, and retaliated by destroying Straxus, leaving the Decepticon fuel auditor, Ratbat, as Cybertron's local Decepticon commander.

Little of import occurred on Cybertron in the immediate future as, more and more, the war spilled over to Earth, with the Autobot and Decepticon commanders summoning more and more warriors to the planet. Ratbat's death in the Underbase affair allowed a triumvirate of three Decepticons – Siezer, Legonis and Octus – to established themselves as rulers on Cybertron while Scorponok led on Earth, but following their destruction by Megatron, and his own subsequent disappearance, their appointed replacement, Thunderwing, took control and dispatched the Mayhem Attack Squad to track down the Autobot Pretenders. When the ensuing battle resulted in the malfunction of a teleportation portal, Grimlock, Bumblebee and Jazz found themselves at the core of Cybertron, bearing witness to the visage of Primus, and learned of his legend from the ancient "Keeper". The Keeper was then struck down by the Mayhems, and the battle that followed briefly awakened Primus, who unleashed a single scream that was heard on the fringes of known space... by Unicron.

As Unicron bore down on the planet, he sent an agent, Galvatron, ahead to sow terror in his name. But Galvatron chafed in Unicron's service and instead awoke Primus, who possessed Emirate Xaaron and teleported every Transformer back to Cybertron in order to unite them, as Unicron attacked the planet. Although Optimus Prime was able to use the Creation Matrix to destroy Unicron, it seemed that Cybertron was to meet its end by other means - tremors and storms began to pervade the planet, which seemed to be tearing itself apart, forcing the remaining Autobots and Decepticons to flee. In actuality, however, the final wave of Matrix energy released in Unicron's destruction had begun a planet-wide rebirth, which was then guided to conclusion by the Last Autobot, restoring and regenerating Cybertron, which the Autobots then occupied.

The above is the story of Primus as related in the United States in Marvel Comics but the story was originally told in British comics. The Primus story is recounted three times under Simon Furman - in order: Transformers UK #150, Transformers US #61, and US #74, and while the Primus/Unicron battle and ultimate solution are always the same, the background to their fight differs in each telling.

The first (told by Unicron) has Primus and Unicron leading armies of similar beings at the dawn of the universe. The second (told by the Primus Chamber's Keeper) had the two as the last of their respective pantheons and Primus needing to stop Unicron before he could pass on from this realm. The third, told by Primus, has Unicron destroying the previous universe and trying to end the current one, with Primus being formed by the "sentient core" of this universe to stop him.

By the third re-telling, the idea that Unicron and Primus were related to similar entities had been dropped and was not picked up again.

In the sequel series to the original "Transformers" comics, more of the history of Cybertron and the Transformer race was revealed, as Optimus Prime discovered that they had once possessed the ability to asexually reproduce by "budding". This was an ability that ceased to function and was forgotten as part of Primus's design, but a group of Cybertronians discovered it and unlocked it within themselves. They continued to multiply beyond the intended limits of their race, diluting their essences until all that remained were single minded killers arrogant in their own supposed superiority - and The Swarm, a dark, destructive byproduct of the reproduction which ventured into space and destroyed other worlds and races, just as these "second generation" Cybertronians left Cybertron under the command of Jhiaxus, and began colonising other planets. When the Swarm returned with the intention of consuming Cybertron, the world of its origin, Optimus Prime used the Matrix to purify it.

In the TV series, Cybertron is a planet once used by the Quintessons as a factory with assembly lines creating soldier ("military hardware") and worker ("consumer goods") robots. (Note: This seems to contradict material presented in the first two seasons of the series. The whole series is full of apparent contradictions and inconsistencies.) Following a rebellion which drove the Quintessons off the planet, the workers became the Autobots and the soldiers became the Decepticons. These two factions eventually engaged in civil war, which forms the basis of the various "Transformers" stories. Some time between the Quintesson occupation and the Autobot/Decepticon war, Cybertron entered a "golden age", with the planet becoming an actual gold color. The energy demands of the war eventually returned Cybertron to its original coloration.

In the first episode, "More Than Meets the Eye Part 1", the dome structure of Iacon retracts to reveal a launching pad for the Autobot spacecraft the Ark. After Autobot leader Optimus Prime and Decepticon leader Megatron journeyed to Earth, crash landing four million years ago and entering emergency stasis lock, Shockwave keeps the planet in stalemate until Megatron awakens in 1984. Cybertron's point of origin within the galaxy was never revealed in the original cartoon, but originally required a dimensional space bridge in order to return to the planet from Earth. Later stories depicted the ability to travel to Cybertron via the use of three interstellar Transformers; Skyfire, Astrotrain, and Omega Supreme. During the first two seasons of the original cartoon, Cybertron was brought into the solar system, and twice was close enough to Earth to be seen by the naked human eye.

Travel between Earth and Cybertron became roughly a half a day's journey, as depicted in the 1986 feature film "". The Decepticons have conquered the planet by 2005, and Cybertron is seen to have at least three moons, two of which are consumed by Unicron. In the aftermath of Unicron's attack on Cybertron, and subsequent defeat, the Autobots are able to reclaim the planet, forcing the Decepticons to retreat to Chaar, a blackened husk of a world. In the final part of "The Rebirth", Vector Sigma absorbed the energies of a near-supernova sun, energizing Cybertron and bringing about a new Golden Age. Unicron's head became an artificial satellite for much of the third season, after his body was destroyed and was reactivated at during the episode "Ghost in the Machine", though it appears to have gone dormant again afterwards. It is unknown what became of Unicron's head when Cybertron was moved into near-Earth orbit during the "Rebirth" episodes, but by the time of "Beast Wars" it is shown that it no longer orbits the planet.

While the American "Transformers" series was concluded with the three-part miniseries, "The Rebirth" (set in 2007), in Japan it was opted to continue the series, and so "The Rebirth" was disregarded in favour of producing "Transformers: Headmasters", a full-length 35-episode series set in the year 2011.

In 2011, it was discovered that the release of the energy of the Matrix by Optimus Prime to cure the Hate Plague had much more far-reaching consequences that anyone suspected. With the Matrix's energy depleted, Vector Sigma's balance – previously tilted in favour of the Autobots by the existence of the Matrix – was reset to neutrality, allowing the Decepticons, bolstered by their new Headmaster troops, to freely invade Cybertron "(known as Seibertron in Japan)". Eventually, this forced Optimus Prime to sacrifice his life by merging with Vector Sigma in order to stabilise the computer before it destroyed Cybertron from within.

Not long thereafter, Vector Sigma developed a new metal alloy dubbed Cybertonuron, which enticed Galvatron into another raid on the planet. However, the Decepticon Headmaster leader, Zarak feared the power that Galvatron would gain from the alloy. To prevent either him or the Autobots from obtaining it, Zarak arranged for his Headmasters to plant bombs at the core of the planet; Vector Sigma's chamber. The Autobots were unable to stop the countdown and the bombs detonating, tearing Cybertron apart and leaving it a charred uninhabitable ruin drifting in space.

Dorling Kindersley's "Transformers: The Ultimate Guide" included illustrations and descriptions of Cybetron’s surface, including an image of Iacon itself. The Guide, first published in 2004, drew on both the Marvel comic continuity and the then recent depictions of Cybertron and Iacon from the Dreamwave "" comic book series. This included elements such as the Stellar Galleries from the latter series, not documented in the original Marvel run. It also depicted Cybertron in a fully realized 'robot mode' as Primus, something never even hinted as a possibility before in the original toyline or comics by Marvel, but which became a reality in, which was the first television series to not only depict Cybertron as having the same transforming capability as Unicron, but also showing it occurring within the show.

In the IDW comics, Cybertron orbits Lambda Scorpii and has been rendered mostly uninhabitable by the war. While Transformers can survive on the surface, they cannot live there indefinitely.

Cybertron's robot mode, Primus was never seen or mentioned in the original U.S. Transformers television series, the writers of "Beast Wars" included Primus to the television mythos with mention of Primus by the Transformers in that series, and the creation of the Covenant of Primus in the series finale.

The expanded fiction of the Botcon and OTFCC comic books suggest that Primus experimented with a small planet before actually transforming himself into Cybertron. This world, named Protos, was where he created the first 12 Transformers, each of them themed after an animal of the zodiac. Later, Primus created the Original Thirteen Transformers.

Primus appeared with Alpha Trion in the "Transformers: Universe" comic, bringing back Optimus Primal and guiding him in his battles against Unicron allied Decepticons.

Cybertron's governing structure during the Beast Wars era is based upon the Pax Cybertronia (Peace of Cybertron). The peace on Cybertron is maintained through a treaty known as the Pax Cybertronia, which – perhaps unfairly – ranks the Predacons as second-class citizens, with the Maximals in control of the planet. Each side is governed by a council;the Maximals governing body is known as the Maximal Imperium while the Predacons' version, the Tripredacus Council, operate out of a satellite orbiting the planet or star, quietly working to their own agenda... an agenda that was sorely disrupted by the rise to power of the renegade, Megatron, who stole a ship and escaped to prehistoric Earth with the intent of altering time.

There are many distinct areas of Cybertron. Ranging from locations on the surface, to any of the number of buried ruins. In "The Reformatting", the first episode of the "Beast Machines" TV show, the Maximals discover the remains of Iacon on Cybertron, deep beneath the planets current surface. The episode suggests that in the intervening years between the end of the G1 / G2 series and the start of "Beast Wars", the inhabitants of Cybertron have built over older city-states with new cities, in a similar manner to an onion skin.

As alluded to in Beast Wars, there is a giant amusement park near the northern pole of the planet. Orbiting Cybertron are a number of structures, such as starports and bases. The Tripredicus Council is established on one of these orbiting bases. There are also a number of communication satellites.

Beneath the cityscape surface of the planet lies layer upon layer of earlier civilizations. One entire Autobot era city lies just beneath the surface. Beneath this city lies ruins of older Cybertronian civilizations, all ending in the rocky core of the planet. It is here that the Oracle of Vector Sigma lies. It is also here that the techno-organic core can be accessed.

In the two groups' absence, Cybertronians had undergone another modification called the "Quantum Cycle Upgrade", in which they were individually fitted with alternate mode scanners so they would not have to rely on external mechanisms to do the job for them. Striking fast and hard, Megatron unleashed a transformation-freezing virus on the populous and deployed a small army of "Vehicon" drones, who extracted the sparks of the virus's hapless victims. Their shells were then used to create more Vehicons, and so it continued until the entire population of Cybertron had their sparks removed, and all that remained were the Vehicons, united under the singular, guiding intelligence of Megatron, who, for all intents and purpose, was now Cybertron itself.

The "" version of Cybertron is never seen (save for once in a flashback in "Ultra Magnus" and "Ultra Magnus: Forced Fusion"). The entirety of the series takes place on Earth. It is unknown what cities, or Autobots and Predacons that could be there, but it is presumably a still living planet. Whether or not it is Primus is unknown. Primus was not mentioned at all, nor Unicron, but Vector Sigma and Alpha Trion exist, as well as the All Spark.

The little information on Cybertron established in the series is that Cybertron was located near or orbiting a larger ringed world, and had an asteroid prison colony in which dangerous Decepticon and Predacon prisoners were interred. At one point there were a series of civil wars, in which Optimus Prime and Ultra Magnus, both creations of Alpha Trion, fought side-by-side. Following the wars, Magnus was honored, but Vector Sigma selected Optimus as Autobot leader and bestowed on him the Matrix of Leadership. The Predacons on Cybertron were ruled over by a council, of which Megatron was a subordinate, though he once claimed to be "leader of the Predacons and future ruler of the galaxy" and that he was already "ruler of many worlds".

Cybertron is the home planet of the Transformers in the three television series, "", "" and "". In the miniseries, Cybertron, Primus' material body, is inhabited by Mini-Cons as well as Autobots and Decepticons, who are unaware the Mini-Cons were weapons forged by Unicron. The war between the Autobots and Decepticons is escalated by Megatron's attempt to gather them. During the escalation, the Mini-Cons liberate themselves and leave the planet in a mass exodus, leading to a four million years (one million years in the Dreamwave comic) stalemate between the two principal forces. Ten years of peace follow "Armada" (2002–2004) and then "Energon" (2014). After "Cybertron"'s climax, the planet has an atmosphere more suitable for humans and organic wildlife.

Long ago, Cybertron was peaceful, until the evil Decepticons waged war against the Autobots. Both sides fought for control of the planet, each ruling one half. Eventually, a mysterious, unclarified "cataclysm" struck the planet, following which the small race of robots known as the Mini-Cons emerged. It would later be discovered that the Mini-Cons were creations of Unicron – currently orbiting Cybertron in a weakened state, disguised as a moon – who had implanted his cells within Cybertron, where they grew and hatched into the Mini-Cons; presumably, then, the cataclysm was caused by Unicron's implantation of his cells. The larger Transformers on Cybertron soon discovered that the Mini-Cons possessed power-enhancing abilities, and began to war over the small robots (it is unclear if the Autobots and Decepticons were already at war, or if it was the emergence of the Mini-Cons which began the conflict).

Through a complicated instance of time-travel, however, the Mini-Cons had the seeds of souls and sentience planted within them at the moment of their creation by a group of time-displaced human children, and as they came to think and feel for themselves, they sought to fulfill their own destiny, by going to Earth to find the humans. The Autobots agreed to aid the Mini-Cons, preferring that they be free and not subject to anyone's will, but the Decepticons still sought to control them, and attacked the launch of the Mini-Con ship, which was crippled as it escaped through a portal, causing it to crash-land on Earth, where the Mini-Cons remained dormant for a million years until they were awakened by the very humans they had come to find. The signal released by their awakening brought the Transformers on Cybertron to Earth in pursuit of them.

As part of the rebuilding program, the Autobot-Decepticon alliance entered into a partnership with Earth's governments to mine Earth and the Sol system for the energy-rich mineral known as Energon. Over the next ten years, Cybertron was steadily restored as "Cybertron Cities" were built in strategic positions on Earth, its moon and Mars to gather Energon and keep the planet rich and healthy.

Following Megatron's resurrection through the power of Energon, he began a quest to restore Unicron to life, under his control, which eventually led him to move the planet-eater's body through a spacebridge into the vicinity of Cybertron itself. After a series of attacks on the planet, during which Primus's chamber was penetrated by Terrorcons, a reaction between the negatively charged Energon within Unicron's body, and the positive Energon used by the Autobots caused a rupture in space, leading to a new sector of the universe where the planets consumed by Unicron had been recreated. A series of battles followed which eventually resulted in Unicron's restoration and destruction, save for his consciousness, which continued to exist within Megatron.

Guided by Unicron, Megatron gathered the remnants of his army and attacked Cybertron once more, using the destruction as a cover for his true motive – to acquire the power of the Super Energon, which transformed into Galvatron. With the aid of Sixshot, the Decepticons were then able to seize control of Cybertron's computer systems, enshrouding the surface of the planet in a poisonous Energon gas that kept the Autobots at a distance while the Energon Towers were used to propel Cybertron through the spatial rift, into the new region of space. Its motion slowed by a giant-sized, Primus-empowered Optimus Supreme, Cybertron was liberated from the Decepticons when Galvatron turned his attention away from it, using the Super-Energon to grow to colossal size himself and departing the world, heading out to find Unicron's spark, drifting in space.

When Galvatron was subsequently possessed by Unicron's spark, Primus used the Super Energon to create a foundling sun, into which Galvatron plunged himself, preferring to perish than to allow himself to be controlled. But, while appearing to be the end of Unicron's threat, in truth, it was the beginning of a much greater danger...

Primus's plan to contain Unicron's spark within the Energon sun was doomed to failure – close to a decade later, the sun collapsed in on itself, turning into a gigantic black hole which threatened not merely Cybertron, the fabric of reality and the multiverse itself, causing ripples throughout space and time that disrupted history, causing inconsistencies between the "Cybertron" animated series and its predecessors. Many Transformers were forced to depart for Earth while the Autobots search for the Cyber Planet Keys to save their world. Over time, it would turn out Cybertron was a dormant Primus. After the destruction of the black hole, Primus turned back into Cybertron with cities, atmosphere for humans, roads and wildlife.

In 2006, a toy of Cybertron was released as part of the toy line. The toy transformed from planet mode into Primus, the Transformers creator. Of the many cities sculpted into the toys surface, one, painted in gold, clearly resembles the illustration of Iacon from "The Ultimate Guide".According to "" comic book by IDW Publishing, Optimus Prime and Megatron co-ruled Cybertron. The Allspark is responsible for giving life to the Transformers. When Megatron begins a war to control it for himself, Optimus sends it into the depths of outer space in the hope that he can defeat him quickly. The war drags on, and Optimus sends Bumblebee to retrieve it, because its absence will cause the planet to shut down. It would later be revealed in the third film that Sentinel Prime was the Autobot leader when the war began and was seemingly killed as he attempted to flee Cyberton with a super weapon. Optimus then took over full command, with the rest of the events likely playing out the same way.

Cybertron's upper layers seem to have a lot of interlocking hexagonal shapes, and several battles near the end of the war took place there. Sentinel Prime used these geographical features to his advantage when he attempted to escape Cybertron aboard the "Ark". Later on, Sentinel Prime attempted to teleport Cybertron via the space bridge-forming pillars from his ship, the Ark in order to acquire Earth's resources to re-energize Cybertron. However, Bumblebee destroyed the master pillar and Cybertron collapsed as it was going through, presumably destroying Cybertron forever.

Geography-wise, the surface of Cybertron is a mystery. Large rivers of liquid criss-cross the planet, though whether this is lava, molten metal, or possibly energon is anyone's guess. In more urbanized areas, such as the city of Tyger Pax, the stone and lava seem to be covered over with steel or other refined metal. However, these incidents took place during the war, so it may have been the result of the devastation Cybertron saw. This liquid is even on the tops of buildings. Internally, Cybertron has similar features to the inside of a "Transformer", including gyroscopic joints. While everyone had abandoned Cybertron, the twin Autobot Skids and Mudflap hung out there for a while, and Starscream began organising an army there in secret. The location on Cybertron that is named after Primus is surrounded by the Rad Zone and Uraya.

Eventually, what little the Transformers knew of their origins would be lost to time. A new society arose, known as the Autobots. The Autobots were a peaceful people, led by Optimus Prime, head of the Science Division, and Protector Megatron, head of the Defense Force. The two leaders created a balance; Optimus was fair while Megatron was firm. Their world's main cities included Tyger Pax, Metrotitan, Simfur, and the capital city of Trypticon. Another area of importance was Burthov, where the Science Division had many facilities. In time, the Autobots began work on a dig near the Simfur Temple, discovering the remains of the Twelve's sarcophagi and the intact sarcophagus of The Fallen. At the same time, unknown alien hostiles attacked Cybertron. Megatron had Optimus remove the intact artifact to his quarters to better protect it, allowing him to come under the influence of The Fallen.

As Megatron began to grow more aggressive, Optimus discovered that he was the orphaned Prime hidden away when the Dynasty fell. Megatron raised an army, the Decepticons, and sought to take the AllSpark to conquer the universe. However, most of the early Decepticon forces left on the "Nemesis" with The Fallen and Soundwave to seek out the harvester. With the number of Megatron's Decepticons now diminished, Optimus assumed his proper title and raised his own army of Autobots. In the war that followed, Cybertron was decimated. Prime eventually sent the AllSpark through a wormhole into deep space, and Megatron pursued it. Both were lost. Without the AllSpark's power, Cybertron became a dead world. The Autobots and the Decepticons scattered across the galaxy, hoping either to create a new world or locate the AllSpark and restore Cybertron. A number of Transformers remained, with the Decepticons centered in Trypticon (now a "Decepticon" capital), but this didn't last long.

Note: Information in "italics" occur in the alternate storyline where Megatron won the battle for the Allspark.

"Cybertron's status was unknown, with everyone abandoning it as it began to die. However, Stockade and a group of Decepticons remained, staying alive by using Nucleon. Stockade believed they could renew Cybertron by summoning a new power source, one related to the AllSpark. They succeeded in summoning such an energy being, which did enter Cybertron to renew it and to everyone's horror, announced itself as Unicron, the Anti-Life! "

"The possessed Cybertron was swiftly altered into a scarier-looking form with a large mouth and grasping prongs, turned hostile to those on it, and warped to the Sol system. The Autobots and Decepticons were able to destroy Unicron, but Cybertron was left in its transformed state and seemingly in the Sol system, as well as continuing to be dead and powerless."

"When the Autobots were ordered off American soil, they regrouped "under" Cybertron and began working on the teleportation engines that Unicron had left there when he transformed the planet. Using these, they were able to make a decisive strike by teleporting the entire Decepticon army to Cybertron, then teleporting "Cybertron" to the far reaches of space. With the engines now burnt out and no energy on the planet, the Decepticons were marooned there, at the cost of the Autobots never being able to go home."

In the early-21st century live-action film trilogy directed by Michael Bay, Cybertron is depicted much in the same way as in the source material: the homeplanet of the Transformer race. As described in the first film, the AllSpark is the origin of life in Cybertron, and over millennia, its population grew and developed a global state, peaceful and just, remaining so for eons until the war for possession of the AllSpark broke out. The war was so devastating that it ravaged the planet until it was consumed by death, and the only way to restore Cybertron to its former glory was through the retrieval of the AllSpark, which is the premise from which the film series start and progress to its climax.

In the climax of the first film, "Transformers", the AllSpark is destroyed to kill Megatron, rendering the restoration of Cybertron impossible. Optimus Prime declares Earth the new home of the Autobots. Cybertron is not shown as a perfect metallic sphere, but a mountainous husk of a planet with large tree-like spires. A region under Decepticon control had dead Cybertronians shown either hung from them, or left on the "branches" that have been ravaged by war.

In the second film, "", Cybertron was mentioned by Optimus Prime when he told Sam that Earth must not share the same fate as Cybertron: "Whole generations lost". Given these statements and the continuous arrival of both Autobot and Decepticon forces on Earth, it is unclear if Cybertron is even populated by its people at this point.

In the third film, "", Sentinel Prime attempts to use his space bridge pillars to transport Cybertron right next to Earth while simultaneously conquering Earth to use humans as slaves to rebuild it. When the transport is interrupted about halfway through, the transported half of Cybertron collapses in on itself and appears to be destroyed.

Cybertron is never seen or mentioned in the fourth film, "", though the Autobots dealt with Lockdown, who works for the Transformers' creators, possibly indicating that Cybertron was indeed destroyed.

In this universe, the Autobots and Decepticons are political factions and Cybertron is a peaceful planet and is considered a multiversal hub, as well as a gateway in between universes. This Cybertron never had a Great War. In one of the oldest dimensions in the multiverse, one Cybertronian city, Axiom Nexus, is a hub for travelers from other dimensions. According to New Arrivals Coordinator Silverbolt, it is a city "unlike any other in the multiverse". To continue its harmony, all Megatrons, Primes, and "MacGuffins" are considered illegal.

Some travelers arrive here by their own design. Others, however, arrive by accident, and must be processed and given identification bolts. These "offworlders" are seen as inferior throwbacks by many of the proud and technologically advanced TransTechs, and permission to travel outside the borders of Axiom Nexus to the rest of its native Cybertron is granted to a very scant few. As such, its inhabitants have a culture all their own, composed of markets and gangs.

In the "Shattered Glass" universe, Cybertron was a peaceful planet whose inhabitants pursued only science and social harmony until the obsessive researcher Optimus Prime rose from the ranks of civilization and began a civil war. This prompted the mathematician Megaron to lead a resistance to retake Cybertron and restore freedom. This Cybertron never broke free of its orbit and continues to revolve around a sun. True to its backwards universe, Cybertron can a frightening and arbitrary place whose natives are born from the Omega Terminus and possess Embers instead of sparks. Following actions taken by Nexus Prime, this Cybertron manifested an evil incarnation of Primus, who later assumed robot form. This forced the noble inhabitants to depart and colonize a New Cybertron.

In this series, Cybertron (サイバトロン, "Saibatoron") is shown as a large planet that's surface is completely covered with metal. Large towers on the surface of the planet are clearly visible from space. Nothing organic has yet been seen on this planet leading to speculation that it is a machine itself. Back in the Great War, the Autobots managed to drive the Decepticons from Cybertron after throwing the Allspark through a space bridge. It is usually seen in flashbacks. Recently, in Season 3, scenes on Cybertron have been in present times. They include Blurr's arrival on Cybertron after being transwarped from Earth. Another is the Cybertronian high court meeting to discuss Wasp, the accused Decepticon spy. The real spy, being Shockwave, also leaves Ultra Magnus wounded on Cybertron, being found by Ironhide.

This version of Cybertron is depicted as having become a lifeless world by the end of the "War for Cybertron" video game and tie-in novel "Exodus". Primus resides in Cybertron's core and creates life through the Well of All Sparks. However, the Well requires the Allspark to function and with it removed during the Great War to prevent capture by the Decepticons, Cybetron became a barren wasteland. At the end of "", Cybertron is revived when the Autobots use the reconstructed Omega Lock on the underside of the "Nemesis". The series' finale movie, "", focuses on Optimus Prime and Wheeljack on Optimus retrieving the Allspark from space while Unicron uses Megatron's body to attempt to destroy Primus/Cybertron. In the end, Optimus succeeds in defeating Unicron and returns the Allspark to the core, but sacrifices himself in the process.

In the sequel series, "", Cybertron is once again home to a prosperous civilization, though Megatronus attempts to extract the Allspark and merge it with the Anti-Spark to destroy both Earth and Cybetron at the conclusion of the first season. In this continuity, Earth and Cybetron are linked, and since it is discovered that Unicron and Primus reside at their respective cores.

In "", Cybertron is an Energon lacking planet with many buildings and bridges destroyed. There are several locations from the Generation 1 universe include the Decagon and the Iacon Vaults. According to the teaser trailer for "War For Cybertron", Cybertron is a satellite of Alpha Centauri. Several times in the game Transformers will exclaim "Thank Primus!" though he doesn't appear in the game. However the Core of Cybertron, (Isaac C. Singleton, Jr.) may actually be Primus, but is credited simply as "Cybertron" in the game's end credits.

In the Decepticon Campaign, Megatron forces Omega Supreme to open the door to Cybertron's core and travels there with his minions. Upon arrival, Megatron infects the core of Cybertron with dark energon. Cybertron is then shown being fully corrupted by dark energon. In the Autobot Campaign, Optimus is given the task of removing the dark energon from Cybertron's core by the Autobot Council. Optimus and his team first attempt to rescue Omega Supreme from the Decepticons, who is being tortured by dark energon. The Autobots manage to free Omega Supreme and rely on Ratchet to repair Omega Supreme to the point of opening the gateway to Cybertron's core.

During their journey to the core they encounter a corrupted space worm, which later attacks the Autobots when they reach the core. Once the worm is destroyed, Optimus speaks with Cybertron's core. The core informs Optimus that it can repair itself, but it will take several million years, time in which Cybertron will become cold, barren, and lifeless. The core then tells Optimus that if he carries a small piece of the core with him, the core will still survive while it repairs. Optimus accepts the burden and the core relinquishes the Autobot Matrix of Leadership. In "", the Autobots and Decepticons depart Cybertron.

However in the series finale "Deadlock", with Megatron's rebuilding of the Omega lock and his death at Bumblebee's hands, the Autobots are able to use it to reactivate Cybertron, restoring life to their home world. In the television film finale to the series, "Predacons Rising", Cybertron is once again threatened by Unicron, who possesses and enslaves Megaton to eradicate the world. At the same time, Optimus leaves Cybertron for the Theta Scorpia star system to retrieve the Allspark, the key to regenerating new life on Cybertron and Shockwave and Starscream clone Predacons to raise an army against the Autobots. When Unicron arrives, he duels the Autobots and sends them retreating and defeats Predaking, the first Predacon cloned (now rogue), and defeats him, heading for the Predacon burial ground Predaking guarded. Once he arrives, he defeats both of Starscream and Shockwave's Predacons; Skylynx and Darksteel, and proceeds to turn the Predacon corpses into undead Terrorcons so they can assault Cybertron's core at the Well of AllSparks.

This article lists characters that appear in "", the third chapter of the "Unicron Trilogy" series of the Transformers franchise. The series features the entirety of planet Cybertron's civilization evacuating the planet to Earth when it is absorbed by a black hole left via the destruction of Unicron. The Autobots act as the main protagonists of the series, with the Decepticons as the main antagonists. Various characters originate from fictional planets shown throughout the series.

List of Transformers: Cybertron characters

Originally, "Cybertron" was created in Japan as a separate standalone continuity called "Transformers: Galaxy Force", but it was dubbed and edited into "Cybertron". During the dub, most characters were renamed into new or previously established character to match with the continuity (e.g. Sideways, Hot Shot, etc.) "Cybertron" features a large cast of characters, something which has not been seen since the original 1980s cartoon. This show also features an incarnation of popular character Soundwave, again, not seen since the 1980s cartoon.

As the Great Commander of the Autobot military, Supreme Commander Optimus Prime ("Soshireikan Galaxy Convoy") organizes the evacuation of Cybertron and the relocation of the planet's inhabitants to Earth when the Energon Sun went supernova. Although a stern and methodical leader, he is a compassionate robot who deeply cares for each of his subordinates. At first, Prime is firmly opposed to interacting with the natives of the worlds the Autobots visit, but soon comes to realize the benefits of the allies the Autobots gain.

Prime transforms into a fire engine, and can convert into a secondary flight mode, or merge with his trailer into Super Mode. Later using the Matrix of Leadership replacing the role of the Spark of Combination, he combines with his fellow Autobot Leobreaker to form Savage Claw Mode ("Liger Convoy"), and with Wing Saber to form Sonic Wing Mode ("Kosoku Kido Soshireikan Sonic Convoy") though the Autobots claim when Prime and Leobraker combine for the first time, "I didn't know Autobots could do that".

Whether he or Galvatron are the stronger, or if both are in perfect balance is unknown, as although Prime did ultimately destroy Galvatron in one final blow, it was with Vector Prime's sword, given to him in the last few seconds before they clashed for the last time. His Cyber Key Power makes his cannons more powerful (""Galaxy Cannon: Full Burst!"). As "Optimus Breaker", his Force Chip special attack was "Liger Grand Break"; as "Optimus Saber", it was "Sonic Double Impact" or "Galaxy Caliber". When he uses Sparkdrinker in Super Mode, he uses "Galaxy Giga Crush".

As Optimus Prime's second-in-command, Jetfire ("Dreadrock") always follows orders, but he is willing to take matters into his own hands to get things done. Now having picked up the native accent of the planet Nebulos (similar to the Australian accent), Jetfire transforms into a cargo plane based on an An-225 Cossack and can unleash a pair of twin cannons through the use of his Cyber Key Power ("Dread Cannon - Full Burst", "Afterburner Blast Attack" in English dub). He also has a turbine wind attack ("Jetstream", "Turbine Wave" in the English dub). In one episode it is revealed that he has a fear of needles. He became leader of Cybertron after Optimus Prime leaves for the Space Bridge Project.

Back in the day, before he joined Rodimus Prime, the elderly Landmine ("Guardshell") trained many young Autobots, including his old friend Mudflap and Optimus Prime himself. During the opening stages of the crisis that sprung up around the black hole, Landmine was transported to Earth by Vector Prime to save him from the black hole's power, where he met and befriended the three human children who became the Autobots' allies.

He transforms into a payloader, and can generate whirlwinds with the bladed wheels unleashed by his Cyber Key Power ("Tornado Cutter", "Cyber Tempest" in the English dub). He also seems to be an homage to the Armada Character Scavenger, in transformation and role (as Optimus' mentor).

Mudflap ("Demolishor") was an Autobot mentored by Landmine who was among those who evacuated from Cybertron and went into hiding on Earth. Growing dissatisfied with the Autobots' mission and human customs, he was persuaded by Starscream to join up with the Decepticons in a misguided attempt to try and save the galaxy without worrying about the affairs of humans.

However, he found he could not stomach the Decepticon way of doing things, and ultimately left them; consumed with guilt over what he had done, he was given a second chance and welcomed back into the Autobot fold by Landmine. He speaks with a French accent.

Mudflap transforms into a crane truck. His Cyber Key extends his crane arm and deploys a massive saw blade ("Mega Crane Blade"), and also activates an arm-mounted missile-launcher.

Wing Saber ("Sonic Bomber" named for the "Zone" Autobot) was first seen in "Energon" as a rebuilt Wing Dagger who could combine with Optimus Prime. Between the events of "Energon" and "Cybertron", Wing Saber let his powers and the Autobots' victory get to his CPU. They had a little trouble rescuing a lost human astronaut from an asteroid belt near planet Chaar. From there, Wing Saber broke every rule in the Autobots' standards, he even attacked Optimus. After the Energon Sun turned into the Grand Black Hole, Wing Saber's memories were warped by the hole's spacetime distortion. He came back as soon as the Autobots and Decepticons tried to take the Omega Lock from Starscream, forcing him and Optimus to combine.

In Cybertron, Wing Saber transforms into an A-10 Thunderbolt II.

The Cybertron Defense Team ("Vanguard Team") is the name Hot Shot, Red Alert and Scattorshot become part of after reformatting themselves.

The brash youth of the Autobot team, Hot Shot ("Exillion"/"Exigeyser") has a need for speed. An avid racer, he takes pride in the fact that he considers himself the fastest in the universe. Once on Velocitron, the Speed Planet, however, Hot Shot finds his title challenged by the planet leader Override, leading to many races, and a personal conflict between duty and ego. Later in the series, after being damaged by Megatron, he is upgraded into a new armored vehicle form as part of the Cybertron Defense Team. Hot Shot becomes the leader of Velocitron when Override is gone, even though he is still an armored APC. The black hole wiped him of his memories of what he was and did in "Armada" and "Energon".

Hot Shot initially transformed into a swift sportscar that could be boosted to even greater speeds through his Cyber Key Power ("Accel Wing"). After being upgraded, he now transforms into a military APC armed with multiple missile launchers, and his Force Chip power becomes "Double X Shot" or "Battle Dagger". The Cybertron Defense Team can combine their Cyber Key special attacks against a single foe ("Triangle Attack"), such as Galvatron.

The Autobots' main technical expert, Scattorshot ("Backpack"/"Backgild") spends most of his time in the base analyzing monitors. Though he can handle his duties with precision, he is known for being quite nervous and unsure of himself. After being damaged by Megatron, he was upgraded by the Omega Lock and made a member of the Cybertron Defense Team, becoming more sure of himself. He speaks with a Southern accent (which possibly is a homage to Ironhide).

Prior to his reformatting, Scattorshot transformed into a half-track missile launcher vehicle with Cyber Key Power grenades ("Ground Shot Up"/"Land Shot", "Missile Storm" in the English dub). In his recreated form as a missile launcher tank, his Cyber Key Power transforms his launchers into a powerful rifle and rocket launcher ("Twin Search Missile" in "Galaxy Force"). The Cybertron Defense Team can combine their Cyber Key special attacks against a single foe ("Triangle Attack"), such as Galvatron.

Red Alert ("First Aid"/"First Gunner") is the Autobot Medical Expert and Chief Science Officer, as well as a long-time veteran of the Cybertronian wars. After the events of Armada and Energon, he gained a British accent. When Red Alert and Hot Shot were sent to Velocitron, his matter-of-factness lead him to clash with the younger Autobot. Later, like Hot Shot and Scattorshot, he gained a new form after being damaged by Megatron and became part of the elite Cybertron Defense Team.

Red Alert initially transforms into an ambulance armed with an electron wrench, a repair hammer, and two Photon Beam cannons activated by his Cyber Key ("Photon Beam"). After reformatting, he became an armored missile launching vehicle, equipped with a massive missile that generates powerful energy blasts ("Giga Vanisher"). The Cybertron Defense Team can combine their Cyber Key special attacks against a single foe ("Triangle Attack"), such as Galvatron.

The Cybertronian starship called the Ogygia came to rest on a barren world, which its inhabitants soon dubbed Velocitron, the Speed Planet. The world was decorated with vast race tracks, and the starship's occupants spent their days competing in races until, by the present day, their descendants filled their time with nothing but. The entire culture of Velocitron is built around racing and speed, and its Cyber Planet Key is, naturally, a racing trophy that can only be acquired by defeating the planet's leader.

Long-time ruler of Velocitron, Speed of Sound Commander Override ("Onsoku Shireikan Nitro Convoy")'s life is dominated by racing, to the extent that she would not impart information, or even hold a conversation with anyone if they did not face her in a race. When Hot Shot arrived on Velocitron, the noble goals of the young Autobot swayed her to their side, and she joined the heroes in the greatest race of all - the race to save the galaxy. Override transforms into a race car (most likely a Lotus), and her Cyber Key power allows her to boost her engine speed ("Nitro Boost"). She is armed with a double-barrelled blaster activated by her Cyber Key ("Mach Shot").

Override was originally conceived as a male character, and appears as such as in "Transformers: Galaxy Force", the Japanese counterpart of "Cybertron". Cartoon Network's desire that the show have a greater female presence saw Hasbro recast Override as a female - a change that, though seeming sheer coincidence, functions very well, given the character's friendship with Lori and rivalry with Thunderblast.

During a regular race on Velocitron, Override was making everyone else eat her dust when suddenly, Megatron appeared right in front of her way. Megatron introduced himself to her and asked where he could find Override, the leader of the planet; as it turned out, he had found her. He asked where he could find the Cyber Planet Key, and Override challenged him to a race to get that info. He accepted, but Override took the victory in a photo finish. She told him she didn't really know about the key and just wanted to race; Megatron promised to tell her all about it at their next meeting. Later, at Override's favorite track on top of a mountain, Megatron again questioned her about the Key. He tried to get the location out of her by offering great reward, but Override was not interested - after all, she already had the Planet Cup, the most valuable object on Velocitron. Megatron copped that the Cup must be the Key he was seeking, and so challenged Override to another race. Just before they began, Hot Shot, who had been spying on the two, jumped in to compete on behalf of the Autobots. Megatron warned that Hot Shot was part of an evil organization, while Hot Shot maintained that it was the Decepticons who were the evil ones. Override wasn't interested in any of this, and told them to just race.

In the race, Megatron quickly fell into third place due to his car mode's inferior maneuverability. Hot Shot raced well and almost won, but was fired upon by Ransack and Crumplezone. Sure enough, Override won, but immediately assaulted the evil duo for assuming she couldn't have won on her own, and they quickly fled. Override complimented Hot Shot on how fast he was and said they could talk about the key next time they raced. She raced against Hot Shot again the next day, and gave him an impressive head start. This proved not to be enough for Hot Shot, however, as Override quickly closed the gap. Hot Shot managed to tap the power of Velocitron and activated his Cyber Key, giving him a speed boost; however, he quickly crashed into a wall, taking him out of the race. Override cruised to an easy victory and drove off, looking forward to racing him again. She later encountered Ransack and Crumplezone bullying Dirt Boss. She tried to help him, only to be brushed off by the victim himself for some reason. Override went on her merry way, unaware that the Decepticons had just gained a new ally. Some time later, while doing laps of her private race track, she was approached by Optimus Prime, who also asked for the Cyber Planet Key. Prime tried explaining the situation, and even asked if he could just "borrow" it, but to no avail. Override told him that she'd heard the same story from both Megatron and Hot Shot; since she had no reason to believe any of them, the trophy would go to whoever won the race.

The next day saw the start of the Planet Cup, with Override as the favorite to win. She got off to a good start, closely followed by Dirt Boss. Hot Shot suffered from some early technical trouble, but soon managed to pull into third. She maintained a strong lead throughout the first heat, finishing first without major interference from the cheaters in the back. In the second heat, Override was pushed into second just before the narrow straightaway. She caught up to the leader, Hot Shot, on the stairs portion of the course by transforming into robot mode and running down them. Hot Shot quickly did the same, while Dirt Boss came up quickly behind both of them, his off-road tires allowing him to traverse the stairs easily. However, Ransack managed to literally leap into pole position by the clever use of springs, and rearranged the direction signs in the city portion to send the leaders on a wild goose chase. Override, Hot Shot, and Dirt Boss all fell for this ruse, but Hot Shot was alerted to the deception by Landmine. Hot Shot told Override about the situation, claiming he wanted to beat her honestly; Override was confused by this display, but still took his advice and returned to the correct track. Soon enough, she once again pulled into first place, but then Ransack and Crumplezone caused the tunnel she was driving through to collapse, trapping her. Hot Shot saved her despite losing first place, again saying it was simply a matter of Autobot honor. This only added to Override's confusion, and she would have lost the race altogether if Brakedown hadn't pointed out everyone else was passing her. In the end, she finished in a respectable third position. Before the third heat, she fitted herself with off-road tires, while Ransack and Crumplezone watched. When the race began in earnest, she avoided much of the initial drama, but eventually ended up being attacked by Dirt Boss, who was frustrated at the idea of someone else doing well in the off-road part of the race. She was saved by the accidental aid of Ransack and Crumplezone, who tried to shoot at her but hit Dirt Boss instead. The three villains fought among themselves, allowing Override to claim first place.

Override was then among the four remaining competitors, all of whom were chosen by the Cup to compete in the final. She and Hot Shot easily pulled ahead of Ransack and Crumplezone, who soon dropped out of the race. The troublesome twosome then tried to steal the trophy, but Override and Hot Shot stopped by to blast them away. They then continued their race, with Hot Shot taking victory in a photo finish. Override was initially shocked, but congratulated him on a well-earned victory and strong competitive spirit. Just as the force field around the Cup came down, Megatron and his cronies arrived to steal it. Optimus Prime, Vector Prime, and Leobreaker arrived from Jungle Planet to stop him, and Override took part in the battle. She and Hot Shot jointly tripped up Megatron, and Override herself grabbed the trophy. With the Decepticons driven away, Override personally presented the trophy to Hot Shot. Impressed by the Autobots' teamwork and collective honor and heroism, Override asked to join them in their quest, and was readily accepted. She accompanied them back to Earth, and as a native of Velocitron, was given the honor of inserting her planet's Key into the Omega Lock. As soon as she did, the Lock revealed the location of the Ancient Decepticons buried in the Arctic. Override accompanied the Autobots on their investigation, but they didn't find anything. When they got back, Coby repaired some of the damage she had suffered, and she promised to take Lori to Jungle Planet when fully healed. Lori would soon get her wish, as Optimus Prime returned from Jungle Planet and asked Override to accompany him to plead his case to Scourge. Override, true to her promise, brought along Lori to represent Earth, over the protestations of the other Auobots; Hot Shot was also present.

When the group arrived on Jungle Planet, they were soon attacked by a group of Decepticons led by Starscream. Override engaged Ransack and Crumplezone, but rather than fight, she challenged them to a race. The two villains quickly sped off to try and win, while Override let them go so she could concentrate on the battle. Starscream and Thundercracker were quickly dispatched, and so Override and the others proceeded to Scourge's temple. Override and Lori both pleaded with Scourge to do the right thing, but the dragonbot was only interested in dueling Optimus Prime and Leobreaker. Prime and Leobreaker won by the use of their Savage Claw Mode and claimed the second Cyber Planet Key for themselves. However, Megatron would not be denied, and attacked Jungle Planet with all his gathered forces. To counter his assault, Vector Prime came up with the idea of distributing several boxes to teams of Autobots, one of which contained the real Key, and the rest were dummies. Crucially, nobody would know which box was which. Override and Hot Shot paired off, and sped into the jungle with one of the boxes. They were pursued by, surprise surprise, Ransack and Crumplezone, who after considerable fighting and racing actually managed to grab the box. Fortunately, it turned out to be a dud (and a booby-trap as a boxing-glove on a spring)—Snarl and Leobreaker had the real one. With the battle won, the Autobots returned to their base on Earth along with new recruit Snarl, and Leobreaker inserted Jungle Planet's Key into the Omega Lock. Once again, the location of the Ancient Decepticons was revealed, this time to much greater precision. While four of them went off to investigate, Override stayed back at the base as backup. It turned out she would be needed, as Optimus Prime, Landmine, and Leobreaker found themselves trapped in a cave with Starscream and many thousands of Ancient Decepticons. Override, along with Hot Shot and Red Alert, raced out to save them, meeting up with Jetfire underground. They saved their comrades, and then returned to civilization to deal with Starscream. They arrived at the scene of the battle, where Vector Prime and Snarl were desperately attempting to hold off the Ancient Decepticons. Worse, they also came under attack by USAF jets, who did not realize the difference between Autobot and Decepticon. Just when things were looking their worst, Evac and Crosswise joined in the fray. They held off Starscream's forces for a while, but were forced to retreat when Optimus Prime was injured. However, some good came out of this—Evac revealed that the third Cyber Planet Key was located on Earth. Unfortunately, it was by then in the hands of Starscream.

The Autobots retreated, Optimus Prime particularly concerned about human civilian casualties. Override offered to let them set up base on Velocitron, and Optimus Prime gratefully accepted. They moved out on the Space Bridge, but just before they could pass through the dimension gate, they were attacked by Starscream. Override and the others made a valiant stand, but Starscream eventually proved victorious, claiming the Omega Lock and the two Keys the Autobots had acquired for himself. As if that wasn't bad enough, Megatron and his crew escaped from the prison in which they had been sealed by Starscream and began to rampage across Earth, together with Scourge. Override took part in the effort to drive them off, working with Crosswise to take down Ransack and Crumplezone. She and Evac then managed to distract Megatron long enough for the heavily injured Hot Shot, Red Alert, and Scattorshot to be evacuated to safety. The two planet leaders actually managed to beat up Megatron to such an extent that he tried to flee into the fire dimension, only for Optimus Prime to douse the portal before he could pass through. His back to the proverbial wall, Megatron lashed out and floored the two of them, only to be stopped by the timely arrival of the three injured parties, now rebuilt as the Cybertron Defense Team". Leaving the lads to try out their new guns, Override, Evac, and Optimus Prime drove through one of Vector Prime's portals to Starscream's island base. Evac brought her to the island by a form of water skiing, during which she shot Thunderblast out of the water. On the island, Override dealt with Lugnutz, at one point actually "riding" him before passing him to Snarl. She also helped beat up Crumplezone, and took part in the first battle against the giant Starscream. Partway through that battle, word came from Cybertron that the Cybertron Defense Team was being overwhelmed by vast numbers of Scrapmetals, and so Override, Evac, and Leobreaker left the battle to go help them out, taking the Omega Lock with its three Cyber Planet Keys with them. Megatron and his forces pursued, and Starscream also sent Thunderblast after them. During their flight, they ended up stymied by a badly warped section of the space bridge which they couldn't cross, and the Decepticons quickly caught up. However, the three managed to tap the power of the Lock and, powered up with burning justice, streaked across space to Cybertron, much to Override's surprise and amazement. Upon arrival, the three found the Cybertron Defense Team desperately fighting a losing battle against the hordes of Scrapmetals. Just after they arrived, Megatron turned up with Scourge, Thundercracker, and Thunderblast, but before they could wipe out the Autobots, Optimus Prime's team came by to save the day. Optimus Prime defeated Megatron in the fire dimension, and there was much rejoicing. The Autobots then plugged the Lock into the space in the Omega Temple, awakening Primus. As the planet itself began to transform, Override and Evac grabbed the kids and jumped off the planet.

When Primus finished his transformation, all the Autobots worked to restore his mind, Override working with Leobreaker. Speaking through Jolt, Primus revealed the location of the last Key on Gigantion. However, before they could mount an expedition, the ghost of Megatron restored himself by the power of Unicron and began attacking. Override and the Cybertron Defense Team followed the specter to see what it would get up to. Megatron restored and empowered the injured Crumplezone, who along with Ransack immediately began harassing Override, leading to a tense chase across Cybertron's streets. Crumplezone was finally taken out by Hot Shot, and after a fight between Megatron/Nemesis Breaker and Optimus Prime/Leobreaker, all the Transformers raced full tilt for the Omega Temple. They arrived at about the same time and began duking it out. The Autobots won, and Override took part in the operation to destroy any remaining Scrapmetals. Override then worked with Landmine as part of an operation to re-energise Primus with the Omega Lock and Optimus Prime's Matrix, but this plan failed when Starscream stopped by at exactly the wrong time and absorbed a chunk of this power, growing to planet size. Primus himself laid the smackdown on Starscream in a particularly awesome manner; after this, Override contacted Clocker and Brakedown on Velocitron and had them (and Dirt Boss, apparently) dig up with "Ogygia" so that the Autobots could travel to Gigantion.

The Autobots loaded up the "Ogygia" and set off on their way, but as they travelled through the wormhole, they were confronted with an asteroid too big to steer around. All of the Autobots combined their Cyber Key Powers to blast a massive hole right through it, allowing them to continue on. On Gigantion, the Autobots met up with Metroplex and Quickmix. After reassuring them that they weren't from Planet X, an alarm was raised that Menasor and the Decepticons were attacking the lower levels. The Autobots and their new friends sped down to investigate, and Override and Evac jointly took on Menasor, eventually beating him. As their search continued, Override was the fourth to be incapacitated by the Cyber Planet Key-powered Megatron, now calling himself Galvatron. She tried desperately to drive away from him, but this time, he was faster than her. However, she was able to warn Optimus Prime, who did manage to defeat Galvatron. When she had been repaired, she accompanied the Cybertron Defense Team and Coby (piloting the Cobybot) in infiltrating the "Atlantis", which Starscream and Sideways had piloted to Gigantion in the meantime. They rescued the imprisoned Bud, Jolt, and Reverb, and then escaped as Quickmix filled with cement the crevasse in which the "Atlantis" was parked. After Bud, Jolt, and Reverb were reunited with the rest of the Autobots, the good guys split into four teams to find a way down to the innermost layers of the planet.

Override was assigned a team with Wing Saber and Lori. They took an elevator to a lower level, where they were confronted by Thunderblast and Scourge. Before any combat could begin, however, Lori began berating Scourge, causing the massive dragon robot to flinch away from the tiny, squishy human until Thunderblast insulted Lori. After that, the robots started shooting; Lori and Wing Saber chased after Thunderblast while Override stayed to fight Scourge, the leaders of Velocitron and Jungle Planet finally coming to blows. This battle resulted in the ceiling getting a massive hole blown in it, and so the two combatants moved to a higher level. Scourge threw his axe at Override and missed, but almost hit Lori, who chose that precise moment to return from forcing Wing Saber to blow up Thunderblast. Terrified of Lori's wrath, Scourge fled, leaving Override and Lori to punch the wall in frustration. However, Lori's punch opened up a secret panel to an information center, where the two of them and Wing Saber were able to learn the story of Gigantion's war with Planet X, as well as the origin of Sideways and Soundwave. With this new information, they quickly rejoined Optimus Prime's team to tell them the story. They all proceeded down to the lowest layer, where they found Bud giving a lesson in leadership to Scourge and the Mini-Cons. Scourge let Metroplex and Vector Prime beat him up, after which Override stepped forward to have her turn, but Optimus Prime went ahead of her and thrashed Scourge so badly that there was no point in fighting him any more. Continuing their journey, they came across the area where the "Lemuria" was said to have lain. Override and Wing Saber sped on ahead to investigate, and found it partially buried in a large lake. Shortly after Optimus Prime's team showed up, Galvatron blew through the ceiling, bringing the remaining Decepticons with him. Wing Saber went back to help Optimus Prime, while Override waited for reinforcements.

Reinforcements soon arrived in the form of Landmine's team. Override and Evac went to join Optimus Prime and aid him in battle, and got smashed by Galvatron. However, they soon recovered and chased Galvatron into the "Lemuria", arriving just as Landmine claimed the final Cyber Planet Key and grew to gargantuan size. Landmine proceeded to lay a massive smackdown on both Starscream and Galvatron, with some small help by Override and Evac. When Galvatron came back and stole the Omega Lock and the four Keys, Override stood back and watched as he fought Starscream, not wanting to get blown up. However, Galvatron still made off with the Lock. The Autobots tried to re-open the portal to their own universe, but they were attacked by a flock of Laserbeak drones, which only dissipated when the machine opening the portal was destroyed. In the end, it required the sacrifice of Vector Prime to return them to their own universe. Upon their return, Override returned to Velocitron to rally her forces against Galvatron's machinations. Just as Galvatron and his remaining Decepticons were preparing for their final assault on Cybertron, Override arrived with every Transformers on Velocitron (they raced there, naturally), at exactly the same time as the forces of Jungle Planet, Earth, and Gigantion arrived. Primus then merged the "Ogygia, Atlantis, Lemuria," and "Hyperborea" into the "Ark", to rid the universe of evil once and for all. However, Galvatron still possessed the Omega Lock, and used it to enlarge all of his loyal followers as well as himself to enormous size. Override led the forces of Velocitron against Crumplezone, exploiting the fact that the big lug's greater size had negatively impacted his maneuverability to cause him to crash into some asteroids.

Meanwhile, Galvatron fled into the deepest core of the Unicron Singularity. Optimus Prime combined with Wing Saber to pursue, but before he got too far, Override, Scourge, Evac, and Metroplex announced their intention to come with him, each to represent their own planet in the final battle. The humans and Mini-Cons also came. The five planet leaders all attacked Galvatron in a massive joint attack, after which the Decepticon commander tossed the Lock into the very center of the Singularity to prevent anyone getting their hands on it. The Keys separated from the Lock, and the planet leaders dived for them. Override grabbed the Velocitron Key, driving around an asteroid to get it. The other leaders were also successful, and they successfully combine the Keys with the Lock. This final act complete, they flew out of the Singularity and used the Lock and Keys to fully restore Primus, who blasted the Singularity closed. However, there were still a few loose ends to tie up. Jungle Planet had been shaken out of its normal location, and Override took part in the effort to restore it. She, along with most of the other characters, also stopped by on Earth's Moon to see Optimus Prime vanquish Galvatron for real this time. With evil defeated and the remaining Decepticons attempting to live peacefully, Override attended the first intergalactic peace conference to represent Velocitron. At this meeting, it was decided to follow in the footsteps of the Ancients and establish a galaxy-wide network of colony worlds, linked by space bridges. Override wished to take part in this mission, but could not leave Velocitron without a leader. To that end, she called a Speedia 500, which was won by Hot Shot. She formally handed over leadership of the planet to the young bot, and some time later returned to Cybertron. She said a tearful farewell to the kids before boarding the "Ogygia" with a large crew of Transformers and departing for parts unknown.

Override is a Female Autobot Warrior rumored to transform into a fluorescent red McLaren 570S with black/carbon fiber accents and a matching red interior. If reports and rumors are true, she will appear in "" with this alternate form, due to the car being referred to as "The Lady" on set. It is also rumored that this same vehicle could be the Decepticon Widowmaker, whose role was replaced with Stinger, the Pagani Huayra KSI drone in "". Whether it is one of the two, an all-new character, a returning character or neither is currently unknown. She also appeared as a Decepticon in the 2010 Transformers toyline as a redeco of Sideways.

Override led the crew of the Star Arrow, which was carrying an experimental Force Chip. The Star Arrow was attacked above Sandokan and crashed on the surface. The crew encountered Synthos, a scrap-monster powered by the Dark Heart. Override and the other Autobots fled from the monster and hid until Astrotrain attacked. When Astrotrain captured the Force Chip and headed towards Synthos, Override followed. She sought to prevent Synthos' Dark Heart from falling into Decpticon hands, but also desired to save the sentient scrap monster. The Autobots captured the Decepticon shuttle that carried Cannonball into battle and used it to capture him, Astrotrain, and the other Decepticons. After depositing them on the other side of the continent, the Autobots fled to Cybertron with the recaptured Force Chip.

Override appears in "". She is one of four Transformers that can be built during this game.A young and spunky denizen of Velocitron, Clocker ("Skids") is a student of the racing master Brakedown, who met and befriended Hot Shot when the Autobot came to Speed Planet. He transforms into a convertible race car, and his Cyber Key activated a double-barrelled blaster ("Smash Burner"). He was in the race for the cyber key, but was dropped after the second race.

One of the oldest residents of Speed Planet and a friend and teacher to Clocker, Brakedown ("Autolander")'s wisdom as an experienced racer gives him a different perspective on situation than others, making him invaluable to young racers in training. Allying with the Autobots after meeting Hot Shot, he transforms into a dragster, and his Cyber Key activates a bladed weapon ("Motor Blade"). His relationship with Hot Shot is comparable to Hot Rod and Kup from the original G1 cartoon. He was in the cyber key race, but was dropped after the desert race.

Dirt Boss ("Inch-Up") is the most specialized Transformer on Speed Planet when it comes to traveling on multiple terrains, from bumpy, uneven paths to muddy quagmires. He hates Override and seeks to defeat her in a race, which proved to be all the reason he needed to join up with Megatron's Decepticons. Defeated in the race for Velocitron's Cyber Planet Key, he broke off his ties with Megatron. He transforms into a monster truck, but can convert to a "high speed mode" with a widened wheelbase through the power of his Cyber Key. In robot mode, his key deploys twin shoulder blasters ("Shoulder Vulcan").

When the Autobot starship the Hyperborea landed on the lush, green world of Jungle Planet, the ship's occupants adopted animal alternate modes, but as time wore on, they and their descendants took on the characteristics of the beasts they mimicked, becoming segregated and bestial. With parties of violent raiders attacking the weaker inhabitants, a feudal law of "Might makes right" came into effect, making the already untamed wilds of the planet even more dangerous.

As a former student of the master Backstop, Dark Commander Scourge ("Ankoku Shireikan Flame Convoy") sought to bring peace to the Jungle Planet, but in using his vast strength to crush all opposition and accomplish his goal, he lost sight of his teacher's ideals and ruled the world through intimidation and shows of power. Hardened and cruel, Scourge espouses the mantra of "Might makes right," but he found his ideals challenged by Leobreaker and the Autobots.

When he was ultimately defeated in combat by Optimus Prime, his pride and jealousy motivated him to join the Decepticons (taking over Starscream's position as Megatron's second-in-command), but from the hard lessons from Lori, Bud, and the Autobots he would learn would eventually turn him to the side of light.

Scourge transforms into a dragon. His tail becomes a massive axe, while his Cyber Key deploys heads over his shoulers in both modes, unleashing a deadly stream of fire breath.

Overhaul ("Jackshot") was once a famous Autobot soldier with a reputation for winning seemingly impossible battles. However, he was considered a loose cannon, and thus, felt alone. As a member of Optimus Prime's team, however, he realized he wasn't completely without friends or allies. Stranded on the Jungle Planet, he engaged planet leader Scourge in battle and called out to the power of the world's Cyber Planet Key when badly damaged, which reformatted him into the bestial Leobreaker ("Ligerjack"). His doubts cause Nemesis Breaker to be born and Megatron gains Dark Claw Mode ability. Ever since he became Leobreaker he tried to take down Scourge.

As Overhaul, he transformed into a military offroad SUV, and his Cyber Key Power allowed him to launch a piledriving missile from his chest ("Anchor Shot", "Slam Attack" in the English dub). Reformatted into Leobreaker, he gained a liger alternate mode and deadly Cyber Key Power claws ("Platinum Claw", as well as "Ultra Liger Drop"), and could now combine with Optimus Prime into Savage Claw Mode ("Liger Convoy", with the Force Chip special attack "Liger Grand Break").

A zen master of combat, Backstop ("Saidos") trained the weaker fighters of Jungle Planet, but at the same time, advocated the values of fighting only when necessary, and striving for peace, rather than fighting for fighting's sake. These were values that his student Scourge could not accept, and he left Backstop's tutelage; when the Autobot Overhaul arrived on the planet, Backstop and his last remaining student Snarl trained him, and sided with Optimus Prime's forces in the battle to save the galaxy. He transforms into a rhinoceros, and his Cyber Key extends his horn into a bladed battering-ram ("Bloody Horn").

As Backstop's student, Snarl ("Fang Wolf") was formerly friends with the planet leader, Scourge. He stayed at Scourge's side to keep an eye on his old friend, until Overhaul arrived on the planet and Snarl was branded a traitor for helping him. He formed a connection with the Autobot, and eventually left his planet to help Optimus Prime save the universe. He transforms into a wolf, with two armor-piercing fangs activated by his Cyber Key ("Power Fang").

One of Scourge's troops, Undermine ("Dinoshout") is somewhat shifty and underhanded. He transforms into a robotic Spinosaurus with a flail weapon for a tail, and a Cyber Key Power that deploys a blade from his fin ("Crest Sword", "Horn Blade" in the English dub). He speaks in an English accent.

One of Scourge's troops, Brimstone ("Tera Shaver") isn't very bright, and relies on Undermine and his leader to do the thinking for him. He transforms into a robotic Pteranodon, and his Cyber Key deploys twin blades from his wings ("Slash Knife").

Eons ago, as part of a program to create a space bridge network linking planets across the universe, four Transformer starships departed for the four corners of the galaxy, each carrying with them a Cyber Planet Key. The starship known as the Atlantis came to Earth, hovering in the skies above the world before a malfunction caused it to crash into the ocean, giving rise to the human legend of the sunken continent of that name. The descendants of the Transformers aboard the Atlantis mostly entered stasis before the present day, though a few continued to operate in secret.

Guardian of Earth's Cyber Planet Key, Aerial Commander Evac ("Koku Shireikan Live Convoy") has existed secretly on the planet for many years, repeatedly switching alternate modes and aiding humans in danger. One such human was a young boy named Franklin, leading the child to pursue knowledge of Transformers for years afterwards. Evac transforms into a rescue helicopter, and his Cyber Key activates a set of thrusters ("Jet Booster") that can also launch missiles ("Falling Missile/Homing Missile/Jet Missile", depending on his mood).

When Decepticons descended from those on the Atlantis began threatening burgeoning humanity, Crosswise ("Autovolt") took on the role of "Monster Hunter" and dedicated himself to capturing and imprisoning them. He succeeded in sealing the Decepticons in stasis beneath the ice fields of Alaska, but he too was trapped, frozen in ice, until Earth's military uncovered him in the present day. Crosswise transforms into a car resembling a Bugatti Veyron, and his Cyber Key activates a set of twin missile launchers ("Force Missile").

Originally, Crosswise was intended to be called "Smokescreen", leading to a production mistake that saw him referred to by this name during the original airings of his debut episodes on Kids' WB. However, by the time these episodes premiered on Cartoon Network, the dialogue had been re-edited to give him the correct name. The mistake was then drafted into a toy.

Although he was one of the Decepticons freed by Starscream, Lugnutz ("Roadstorm") had very little interest in actually fighting for him. He's a very easy-going 'bot with a relaxed, hippie-like attitude that means he would rather be cruising Earth's highways than fighting Autobots. If any of them were to get in his way, though, he wouldn't be averse to blowing them away with his rifle, Dutch. He transforms into a motorcycle, armed with a grenade launcher activated by his Cyber Key ("Side Machine Gun").

The fourth and final Autobot ship, the Lemuria, landed safely on this world. Some time into the colonisation of the planet, it fell victim to a tear in reality, and slipped through a wormhole into another dimension, where it was attacked by the warmongering inhabitants of the vile Planet X. Through the power of their Cyber Planet Key, the planet's inhabitants became gigantic in size and fought back, leaving Planet X with no option but to use their mightiest weapon, only to wind up destroying themselves in the process. Saddened by their planetary level of destruction, the Gigantions dedicated themselves to "con"struction, covering their planet with gargantuan cities which they completed and then abandoned, moving on to the next project. To continue this ongoing task, they built new layers on top of the cities, repeating the process over and over, until the planet itself was colossal. In addition to the giant Transformers, Gigantion is also populated by Mini-Cons, who perform the small, intricate, detailed tasks of construction that the larger robots cannot.

For whatever reason, all the inhabitants of Gigantion speak with Scottish, German and Irish accents.

The leader of the Transformers on Giant Planet, Open-Mind Commander Metroplex ("Kyoshin Shireikan Megalo Convoy") is the largest of the large, the bravest of the brave and the kindest of the kind. In the English dub, he speaks with a Scottish accent. He is physically powerful enough to best Megatron in mere seconds (an unequaled feat amongst the Transformers of this era), and joined up with the Autobots almost as quickly. He transforms into a bucket wheel excavator, and wields a gigantic axe, called Sparkdrinker. He can also assume a smaller "work mode" for more precise tasks.

He is partnered with the Mini-Con Drill Bit ("Horribull"), who becomes a drilling vehicle. He can mount on Metroplex's right arm or the back of his axe. He functions as a coordinator, and plans all of the Mini-Con work in Gigantion. Many of those Mini-Cons consider him the leader of their planet.

Metroplex lends Optimus Prime Sparkdrinker for Optimus to use as a bludgeoning weapon ("Galaxy Giga Crush"). His Cyber Key powers up Sparkdrinker ("Megalo Crush/Axe Crusher"), or he can throw it like a boomerang (albeit a very big one) ("Megalo Boomerang").

Quickmix ("Blender") is Metroplex's right-hand man and knows "a lot about a lot". His skill is as an advisor and a technical worker, but he can fight just as well as anyone, with a Cyber Key Power that transforms the drum of his concrete mixer alternate mode into a blaster ("Mixing Cannon").

His Mini-Con partner is named Stripmine ("Killbull"), who transforms into a mining vehicle. He helps to operate Quickmix while the latter is in vehicle mode. Stripmine's function is Heavy Machine Operations.

A young Transformer from Gigantion who wanted to change his world's seemingly "out-dated" philosophy by force, Menasor ("Moledive") fell prey to Megatron's influence, and joined the Decepticons. Ultimately, his Mini-Con partner Heavy Load ("Bull Bull") showed him the error of his ways by leaping in front of Menasor's own drill. Unable to harm his own partner, he saw that he would only hurt Gigantion, and joined Metroplex and the Autobots. He transforms into a large-scale drilling machine, while Heavy Load becomes a dump truck. His Cyber Key power increase the power of his drills. His Force Chip special attack is "Giant Drill".

As one of the first thirteen Transformers created by the race's deity, Primus. Vector Prime hails from the very beginning of Cybertron. Having removed himself from the linear universe eons ago, he existed outside of time, watching over the multiverse until the threat of the black hole emerged, forcing him to return to Cybertron and alert Optimus Prime's Autobots to the power of the Cyber Planet Keys. But at last, Vector Prime sacrifices himself to save Cybertron and to open the warp gate.

This trio of Mini-Cons hail from Gigantion, but were stranded in space and time when a game of hide and seek went away. Discovered by Vector Prime, they were brought to Earth by him, where they quickly befriended the Autobots' human allies Bud, Coby and Lori, due to having minds that function like human children's.

The Cobybot ("Coby Ramble" in "Galaxy Force") is a Scrapmetal that Coby Hansen refitted as his own pilotable Transformer in the "Cybertron" series. Like most of the Scrapmetals, the Cobybot transforms into a "spider-tank" vehicle. Its special attack is "Hissatu Coby Shot".

A Coby Ramble toy was released as part of the EX-02 Sonic Convoy, which is a giftset that was released exclusively for Toys "R" Us Japan. A reviewer at TFORMER (a division of Entertainment News International) noted that the Coby Ramble toy was simply a "remold and repaint".

Another "Galaxy Force" Coby Ramble toy, a remold of the Scrapmetal toy, was made exclusively for Takara.

Trapped within an energon sun at the conclusion of "", Master Megatron was freed from his imprisonment when the sun collapsed into the massive black hole that threatened Cybertron. Having absorbed the remnants of Unicron's armor and power into his own body, Megatron is now arguably the most powerful Decepticon, and seeks to use the power of the Cyber Planet Keys and the black hole to remold the universe in his own image. Despite recruiting natives from all the different worlds that the Transformers visited, Megatron was continuously met with failure, but upon his defeat by Metroplex on Gigantion, his Armor of Unicron tapped into the world's Cyber Planet Key and upgraded him into the insanely powerful Master Galvatron. He won more battles as Galvatron and stole the completed Omega Lock for many episodes.
Megatron is a Triple Changer, transforming from a Batmobile-like dragster into a Cybertronian jet. He can project devastating electrical blasts from his hands, and his Cyber Key activates many powers, including vehicle-mode thrusters, a claw shield ("Death Claw") and his deadly "Death Machine Gun", ("Death Machine Gun") with which he fatally injured Hot Shot, Red Alert and Scattershot. He could also combine with Nemesis Breaker to form Dark Claw Mode ("Liger Megatron") for a short period of time, with a similar Cyber Key power to Optimus Prime's Savage Claw Mode Cyber Key attack ("Liger Death Strike").
As Galvatron, he retained all his previous attacks, could project dark energy, and shape it into a sword. In his final battle with Optimus Prime, he gained a new transformation in which his back wings/cape formed a cannon on his chest, which fired dark electrical energy ("Death Cannon"). His armor can also restore him.

The only Decepticon to take on an Earth mode, Thundercracker was first mentioned in "Armada" when Starscream was contemplating his supercharged color scheme. When Cybertron came to air, Thundercracker was an enthusiastic fighter somewhat lacking in intelligence and combat skills who spoke in a Southern drawl accent. He has a tendency to come up with grand but largely ineffective special attacks (The Japanese version has him parodying lines said in Mecha anime characters), and would rather be a "winner" than be evil. He transforms into a Su-27 Flanker, and his Cyber Key activates the blaster in place of his left arm and in jet mode the Cyber Key power gives him a gun on his back ("Thunder Hell, English: Thunder Cannon /Super Hell Special Deluxe/Big Spinning Thunder Hell Scattering Fireworks, English: Rain of Ultimate Destruction/Sure Kill Ultra Hurricane Slash And Crush Shoot, English: Triple Spinnin' Laser Willmaker/Drill Spinning Thunder Hell Electric Drop/Hissatu! Super Electric Lightning Shock Electric Thunder Cracker Punch!, English: Super Electric Lighting Thundercrackin' Punch/Hyper Ultra Big Missile Full Burst Maximum Alpha!/Hyper Ultra Big Missile Full Burst Maximum Beta Two"). The Decepticons often ride on him a lot.

Also freed from the sun upon its collapse, Starscream assumed the position of Megatron's second-in-command. But his experiences throughout the "" and "Energon" conflict had shaped Starscream into a bitter mech with his own ambitions, and he sought to acquire the power of the Cyber Planet Keys himself. Scheming with the mysterious Sideways, Starscream liberated the ancient Decepticons trapped on Earth and acquired the Omega Lock and three Cyber Planet Keys, allowing him to tap the power of Primus and grow to a gigantic height. Operating as a third factor in the remainder of the conflict, Starscream battled with Megatron, Optimus Prime and even Primus himself by growing skyscraper size and planet size.

This big green brawler is the muscular half of the "Gruesome Twosome" and is hardly ever seen without his partner, Ransack. Crumblezone ("Landbullet") is not especially bright, but his bulky frame possesses incredible speed when in his three-wheeled dragster mode, and great strength in robot mode. During a later battle on Cybertron, he was badly injured by a horde of Scrapmetal, but Megatron used the power of his Unicron Armor to reformat him into "Dark Crumplezone" ("Armbullet"). His Cyber Key Power activates a pair of massive missile launchers ("Land Bazooka", "Arm Bazooka" after his upgrade). In the final Planet Cup race, he modified himself to give himself extra speed ("Ultra Tune Level 2 Ignition"), but still lost.

The smaller and more "intelligent" member of the "Gruesome Twosome" (although that's not saying much), Ransack ("Gasket") makes up for his small size in nimbleness, agility, fairly quick wits, and the fact that he has a bigger partner that can beat up people for him. He transforms into a motorcycle with Cyber-Key-activated boosters that act as a double-barrelled cannon in robot mode ("Exhaust Shot/Exhaust Boost"). In the final Planet Cup race, he modified himself to give himself extra speed ("Reverse Tune Ignition"), but still lost.

An evil doppelganger of Leobreaker who was born from Leobreaker's doubts and the dark power contained in Megatron's Unicron Armor. Nemesis Breaker ("Dark Ligerjack") can combine with Megatron into Dark Claw Mode ("Liger Megatron", with the "Liger Death Strike" Force Chip attack), in opposition to Optimus's Savage Claw Mode. His Cyber Key power is the same as Leobreaker. He is more beast than Transformer, and only speaks through growls and roars. Ultimately, he was destroyed by Metroplex, returning him to the darkness from whence he came.

The Earth Decepticons are the descendants of Transformers who came to Earth on the starship Atlantis. They were sealed away by Crosswise, but were freed by Starscream.

Thunderblast ("Chromia") is an ancient female Transformer who was locked up by Crosswise and initially served Starscream, but turned to Megatron's side based on how hunky he was. She has a flighty, fun-loving, girlish personality, but ultimately, her only loyalty is to herself, and she will join whomever is most powerful. She transforms into a speedboat, and her Cyber Key transforms her missile launcher weapon into an even larger rocket launcher ("Phantom Wave"). She is also lava impervious as she once swam on it, and she is a master of water travel.

Planet X was home to weapon manufacturers/dealers, thieves, murderers and villains of all walks of life, who took their planet on a voyage of galactic conquest and destruction. That voyage came to an end, however, when Planet X encountered Gigantion, and destroyed itself in the ensuing war. The scattered survivors of Planet X allied themselves with Unicron in hopes of attaining revenge on the Giant Planet in the future, and served his will by acting as enigmatic operatives of misdirection and distrust amongst the Transformers.

This master of deception had previously served Unicron by acting as an avatar for his spark during the war for the Mini-Cons in "Transformers: Armada", and was preserved by his dark power following his seeming death at the end of that conflict. Returning during the search for the Cyber Planet Keys, Sideways ("Noisemaze") aligned himself with Starscream, considering him the best chance he had at revenge against Gigantion.

Sideways transforms into a spacecraft. His Cyber Key activates an arm-mounted bladed weapon, and switches his faction signal back and forth from Autobot to Decepticon.

Soundwave makes his entrance later in the search for the Cyber Planet Keys, offering to guide Megatron and the Decepticons to the wormhole that would lead them to Gigantion. Once on the planet, he joins with Sideways, and they both attempt to acquire the Omega Lock and Keys for themselves, only to be blasted into another dimension. Unlike his other counterparts, this one sounds like a deadpan 80s' rave club DJ.

Soundwave transforms into a stealth jet fighter, and is partnered with the Mini-Con-like robot, Laserbeak ("Killer Condor"). Laserbeak transforms from a condor into a battery bomb that stores in Soundwave's chest compartment, which deploys through use of his Cyber Key ("Blaster Gun"). (The animated version of Soundwave is not shown using his Cyber Key to "eject" Laserbeak, or to use it at all.)

An army of drone-like, mutant mechanical lifeforms. While they bear the Decepticon symbol, they serve neither Megatron or Starscream, and act like swarms of vicious insects. They come from worlds neighboring Cybertron, and swarmed to the planet when it was abandoned during the black hole crisis. They were faced down by the Cybertron Defense Team, who wiped out a large number of them. However, the Scrapmetal population clearly survived, as shown by the swarm that attacked and nearly killed Crumplezone. Later, a destroyed Scrapmetal was used by Coby to create his own pilotable Transformer, the Cobybot. They all transform into "spider-tank" vehicles, and come in varieties of red, blue, and yellow. They too have a cyber key and powers which make their cannons unsheathe a sword, but this was never seen in action.

The benevolent creator of the Transformers, Primus is the true form of the planet Cybertron. Each of the Cyber Planet Keys contains a portion of his power; upon the collection of all but the Gigantion key, Cybertron transformed into Primus's robot mode and defeated Starscream in battle using his own moons as weapons. Subsequently, the acquisition of the Giant Planet key reunited Primus's spark with his body, and he used his power to seal the black hole and recreate Cybertron as a new, idyllic world. His Cyber Key power unleashes energy from his hands which he used on Starscream but he deflects it.

As Primus's brother and ancient foe, Unicron sought to destroy life where Primus sought to protect it. Having been battled by the Transformers in previously in "Armada" and "Energon", Unicron was ultimately defeated when his spark was imprisoned by Primus within an energon sun. The destruction of Unicron - the embodiment of evil - in this manner, however, caused a fundamental imbalance in the universe, which caused the sun to collapse in upon itself, creating the massive black hole that threatened not just Cybertron, but the entire multiverse. Although Unicron does not bear a Decepticon insignia on his body, he is assumed to be on the Decepticon side due to his extreme level of evil and his rivalry with Primus.

Coby Hansen (voiced by Samuel Vincent in English and by Yukiko Tamaki in Japanese) is the primary human character in "Cybertron". The character has been used in the television series, comic book series, and collection of children's toys manufactured by Takara Tomy in conjunction with Hasbro. In the series, he is a mechanically-inclined 14-year-old who is often called on by the Transformers to do repairs. He lives in Colorado with his younger brother, Bud, and older brother, Tim and enjoys dirtbike racing and has worked at a mechanic's shop. Coby and Bud, along with their friend, Lori (the only female of the series), befriended the Autobots after finding and aiding the damaged Landmine. He develops a friendship with Landmine, and aids Hot Shot on Velocitron.

Later in the show, he actually refits a destroyed Scrapmetal as his own personal vehicle called the Cobybot (""Cobyrumble"" in "Galaxy Force"), earning himself an Autobot Commission and an active role in the battles after he used it to save Bud, who was trapped among the Decepticons. He is very protective of his little brother Bud.

From the onset of the series, Coby has a somewhat antagonistic relationship with Lori; their first conversation is an argument (in the Japanese version, she mocked him for liking machines to living creatures). However, as the series progressed, the two of them developed a strong unspoken bond, strengthened by their time with the Autobots.

In the finale, as the Autobots prepare to leave, in order to begin construction of a new space bridge, Coby is joined by Lori as he sits on his drone. He tells her that he intends to study hard and someday go up into space to help out; Lori replies to the effect that she'll see him there. The pair hold hands and (in a first for a Transformers series) share a kiss.

The epilogue montage shows both Coby and Lori in space suits, successfully keeping their promise to meet up in space. The final scene of Galaxy Force is a picture of their wedding, surrounded by their family members, as well as Landmine, Six Speed, and Optimus Prime in the background together.

Coby's younger brother, Bud is a kid through and through. He likes things that kids like, and he daydreams like kids do, although in Bud's case, his daydreams often become reality thanks to his friendship with the Autobots. Very little can phase Bud - his unrelentingly positive attitude keeps him from worrying too much about anything, even the possibility of his own demise. As the ending credits of the final episode show, he won an Academy Award for the documentary he produced about his adventures.

Lori Jiménez (voiced by Sarah Edmondson in the US dub) is the most level-headed of the group, keeping Coby and Bud under some degree of control. As a city girl, she was not best pleased when her parents moved from a city to a small town in Colorado, but the adventures she had with the Transformers soon took her mind off that. Along the way, she gains a friendship with Override and forms a connection with Scourge - both referring to her as "little sister". She even developed a rivalry with the female Decepticon Thunderblast. The ending credits show that she and Coby eventually get married.

When the young Franklin was saved from a raging river as a child by Evac, he dedicated himself to acquiring information on the Transformers, eventually becoming a government agent and, to the surprise of the Autobots' child friends, an ally of the Autobots themselves. At the end of the series, he developed a romance with Dr. Suzuki, who - to his surprise - revealed they were engaged. The ending credits show that they do get married and have a child.

Professor Suzuki (voiced by Tabitha St. Germain) is not exactly held in high standing amongst her scientific colleagues due to her ideas about alien beings and the Hollow Earth theory, but that doesn't bother her. She quickly and easily befriends Coby, Bud and Lori due to their own open-mindedness about her theories, and becomes involved in investigating the Transformers for the government. When Colonel Franklin revealed that his motives were peaceful, she became friendly with him, and eventually decided that they were going to get engaged. The ending credits show that they married and have a child.In the series, multiple "extra" Transformers have been shown, with most of them serving as the general inhabitants of the various planets.

Autobots living on Earth while Cybertron is threatened by the black hole. Several of them have proven to be recurring characters.The denizens of Speed Planet. Most appear in the form of cars (most resembling the "Blurr" model), or in robot modes that resemble the usual generic models used in the series. There are, however, some notable exceptions.

The denizens of Jungle Planet. They all appear in animal form, and have transformations ranging from modern, mythological and prehistoric creatures, which means they must have visited Earth at some point. They include several that resemble an Apatosaurus, an owl, a deer, a giraffe, and a tropical bird.

Descendants of the original Transformers who came to the planet on the starship Atlantis. They inspired legends of monsters & supernatural creatures among the people of Earth. They were all captured and sealed in stasis pods by Crosswise for a number of years, until they were freed by Starscream. They have the ability to project an image around themselves that resemble cryptids (examples being Count Dracula, a werewolf, Bigfoot, and some dragons). They can also transform into large "Seeker ships" by merging with one another. They were all defeated and re-sealed, with the exception of Thunderblast and Lugnutz. However, Evac and Crosswise made a deal with Lugnutz, and released them to help in the final battle against Galvatron. Ultimately, a large number of them joined the space bridge project at the end of the series.

The people of this planet all transform into construction equipment.

In the past, Planet X was populated by "mass production" types similar to Sideways and Soundwave, as well as numerous Mini-Cons fashioned in the same model as Laserbeak. There is a Japanese exclusive toy called Soundblaster, and his minion is a Laserbeak-type named Hell Buzzsaw.

Available exclusively to members of the Official Transformers Collectors Club, the short bi-monthly comic strip published in the club's newsletter - in addition to explaining away the plot holes that exist between the "Armada", "Energon" and "Cybertron" animated series - expands the story of "Cybertron" to include many other characters. Primarily, these characters are from the parallel-universe-spanning "" toyline, but the comic has also featured several of the "Cybertron" characters not featured in the animated series. These include:There are a number of Transformers in the toyline that do not appear in the show, most of which are American-exclusives.

The "Cybertron" series features a strong presence from Mini-Cons, in the form of numerous repaints.

Cybertron is a fictional planet, the homeworld of the Transformers
