The planet Cybertron, as seen in the original series. Not pictured: Realistically sized buildings.

Cybertron is the home planet of the Transformers and (usually) the body of their creator, Primus. Cybertron is (almost always) a shining metal, technological world; a planet of towering future cities without end and vast metallic plains, spiraling metal mountains and bottomless neon-lit chasms. Battling over control of Cybertron and its resources is frequently the motivation for, or origin of, the Transformers' epic wars. Beyond these facts much about Cybertron can differ between continuities, see individual entries below.

“ This world is older than you can imagine. It has sailed the starscape...tending budding galaxies...forever a buffer to the approaching darkness. And now its fate...is in your hands. ” —A voice to Optimus Prime, The War Within #6

Marvel The Transformers comics

Events from the UK-only comic stories are in italics.

Cybertron was the adopted form of the lord of the light gods Primus, who trapped himself and Unicron in barren asteroids which they then shaped into their physical forms. While Unicron turned his prison into a transformable, humanoid body, Primus reformed himself into a vast Saturn-sized machine-world, home for a robotic race he created to fight Unicron with similar transformation abilities. The Primal Scream

It has been suggested that the Demons in the darkness were the world's original inhabitants, locked away beneath the world by Primus, though this remains unconfirmed.

Aside from the Transformers, the world seems to possess the mechanical equivalent of plant and animal life, though the exact nature and origin of this lower "life" has never been examined in detail. This version of Cybertron has rough hewn mountain ranges and great seas. (Though of note these seas are not made of water. Liquid water is so rare on Cybertron as to be thought a mythical substance. Alternative substances these bodies are filled with are mercury The Smelting Pool! and liquid helium The Primal Scream/Darn 'n' Blast #303) The atmosphere and temperature on most of the surface is such that human life can survive unaided.

Just another Alpha Centauri sunrise.

In its earliest recorded era Cybertron orbited Alpha Centauri, and the Transformers were at peace. The Transformers From an unknown point of time, Cybertron was ruled by the Overlords, a governing council of absolute rulers. Over time, their power and number dwindled, until Cybertron was composed of multiple city-states who were constantly clashing with each other; the key three powers were Vos, Tarn and Iacon. While all the major cities were using their might to pork energy at the expense of others, Iacon did ration theirs out to neighbouring smaller cities. Tarn and Vos, by comparison, built up vast armies. In an attempt to lessen growing hostilities caused by the splintering governments and the dwindling resources on Cybertron, the last Overlord started the Games: an inter-city gladiatorial tournament. This allowed the population to exorcise their hostilities, and soon the vicious athlete Megatron had a cult of personality based around him and his feats. He built this up, quietly planning to unite Cybertron under his own rule and turn it into a mighty cosmic dreadnought! One of his great rivals was Optimus Prime, the champion of Iacon.

Vos — ruled by a Starscream-headed criminal syndicate — sent its athletic team to bomb Tarn (ruled by Shockwave) and finger Iacon as the culprit. As with all plans by Starscream, this cocked up — Tarn realised Vos had attacked it, and war broke out that devastated both cities. Iacon happily let its rivals beat on each other. During the conflict, Optimus Prime tries to get the Overlord to safety but Megatron secretly ensures the leader starves to death; once the war ended, Megatron used his fame and charisma to convince the war's survivors that Iacon was at fault for not stepping in to prevent the war, and that Iacon was the enemy. This angry mass became the first Decepticons. State Games

Megatron rallied his army to march on the Autobot cities, conquering large swaths of Cybertron until Optimus Prime arose from the Autobots ranks to match his old foe. Megatron's ultimate aim was to turn Cybertron into a "cosmic dreadnought", intending to his homeworld as a galaxy conquering warship. The Transformers To achieve this, Megatron constructed a prototype set of planetary engines in Kalis. Meltdown!

Before Megatron could achieve his dream, the sheer firepower unleashed by the Great War tore Cybertron from its orbit and sent it hurtling aimlessly throughout the cosmos. When it passed through the Sol system, the asteroid belt threatened to destroy Cybertron forcing the Autobots to use the Ark to clear a path for their world. Though they were successful, they were ambushed by Decepticons led by Megatron, and their battle ended with a crash-landing on Earth that left all the combatants deactivated. Their compatriots on Cybertron mourned their loss but continued the wars. The Transformers

The young warlord Trannis seized on his opportunity and assumed command of the Decepticon forces, reorganizing the army and conquering all but Iacon. After a long stalemate, Trannis decided "screw it" and razed Iacon, finally putting Cybertron under Decepticon rule. As the centuries passed, Trannis grew complacent in his rule allowing the Wreckers to assassinate him which only served to allow for the more brutal Straxus to take command. Cybertron: The Middle Years!

By 1985, the Autobots had been forced into guerrilla warfare against their foes. When the Earth-bound Transformers contacted their homeworld, the Decepticons made plans to connect the two planets via space bridge. The Smelting Pool! Though Perceptor's resistance cell managed to destroy the bridge and kill Straxus, they were left stranded on Earth. The Bridge to Nowhere!

Don't worry, if Unicron eats this Cybertron, Marvel can xerox another copy of the model sheet.

After Optimus Prime's physical demise, Megatron went properly off his rocker and blew up the space bridge he was standing on, Gone but Not Forgotten! which transported him to the Dead End on Cybertron, spending the next few years as a mindless Empty. The Resurrection Gambit!

Circa 1990, members of the Ark crew fought with the Mayhem Attack Squad in a chamber containing the giant head of Primus. A stray shot hit the god's face, and he awoke with a scream that alerted Unicron to his location. The Primal Scream

When the Chaos Bringer arrived, the Autobots and Decepticons united against him, but the battle still wreaked havoc on the planet. Unicron was defeated by the opening of the Creation Matrix, but only after he'd already destroyed Primus. On the Edge of Extinction! In the aftermath, Cybertron suffered storms and earthquakes that many believed would tear the world apart. Exodus! The remaining Transformers evacuated, but Cybertron was ultimately saved by the united efforts of Optimus Prime and the Neo-Knights who awakened the Last Autobot. The Last Autobot? The ancient steward revealed that upon the Matrix's opening, the planet had been bathed in its energy and was in fact healing itself. After he guided the process in a steady manner, he and Prime recalled out the Autobots before returning the humans to Earth and finally bringing peace to the metallic planet. End of the Road!

Significant locations

Cybertron has two moons. The Bridge to Nowhere!

Cybertron was historically organized into city-states, the largest and most important being Iacon. Others have included Kalis, Tarn, and Vos. Within the province of Polyhex was the Decepticon stronghold called Darkmount.

Beneath the Mutant filled sewers, the Demons in the Darkness were locked away.

At the center of this Cybertron there was a room with a huge head of Primus on the wall where he slept and was watched over by the Keeper. Somewhere within the depths of Cybertron could also be found a chamber containing the Last Autobot.





Regeneration One

Before creating the Cybertronians, Primus created the Demons as a first run. The creatures' free will however caused them to turn each other and Primus attempt to wipe the slate clean. Though most perished, a few survived beneath Cybertron's surface, unnoticed by the Cybertronians who took their place. Natural Selection, Part Four

Prior to the Great War, Cybertron had trade relations with other mechanical planets. The War to End All Wars, Part 1

As Cybertron reconstructed itself following Unicron's defeat, the Dark Matrix entity merged itself with the planet infecting every crack and becoming one with it as Primus had done before. The War to End All Wars, Part 5 After the end of the Great War, the Pax Cybertronia was signed which brought peace to the planet. Loose Ends, Part 1

After 21 years of relative peace, however, the planet was again thrown into the fire by the machinations of the Dark Matrix entity, The War to End All Wars, Part 5 marked by the destruction of the Last Autobot. Counterpoint After learning that Megatron still lived and was wreaking havoc on Earth, Optimus left the planet under Hot Rod's leadership. Loose Ends, Part 3 Scorponok planned to use a Gene Key to turn all on the planet into Decepticons. Natural Selection, Part One Though the Decepticon was halted, his scheme had caused great damage to Cybertron, Natural Selection, Part Five with many turning themselves in or asking to be prosecuted for war crimes. Destiny, Part One Cybertron however was soon invaded by Bludgeon's Warworld, Destiny, Part Three which soon turned into all out war before the Wreckers destroyed the ship. Destiny, Part Five

As Cybertron began (another) cleanup, rogue senator Jhiaxus arrived, The War to End All Wars, Part 1 and offered to integrate Cybertron into the Hub Network. The War to End All Wars, Part 2 The Autobots soon went to war with the Hub and while they were offworld, the Dark Matrix struck out on Cybertron, turning everyone on the planet into shadow-leeches. Hot Rod, now Rodimus Prime, eventually realized the Dark Matrix creature had been posing as Primus and confronted it in Zero Space. There, Optimus Prime revealed the entity's plan to Rodimus and that the only way to prevent it was to sever their own reality from the multiverse which Rodimus reluctantly did. Cut off from Primus, Cybertron and its people became mortal, with the latter abandoning the planet in the aftermath. When Rodimus Prime returned to Cybertron after untold eons to finally die, the last vestiges of his Spark energy flowed to one of the stasis pods inhabited by the Demons and a new breed of Cybertronian emerged to tame the planet. The War to End All Wars, Part 5

Transformers '84

After Cybertron had been ripped from its orbit, Shockwave test fired a planetary turbine that the planet towards the dangerous Stellae Cimeterium to try and have Megatron refocus on Project Dreadnought to no avail. Secrets & Lies #1

Despite this, Optimus Prime felt that Megatron represented the greatest threat to Cybertron, not least because Cybertron's errant course could be halted by a series of controlled explosions, and launched the Ark in an attempt to lure Decepticon High Command off Cybertron forever, entrusting Punch to ensure that Megatron never saw their home planet again, so that the Autobot army could have a fighting chance.

Generation 1 cartoon continuity

The Transformers cartoon

And that, my friends, is when you say "Look out below!"

Cybertron appeared considerably smaller than the planet Earth. Entirely metallic on the surface, some of the lowest levels of Cybertron consisted of rock and dirt, suggesting an organic beginning to the planet. Its gravity was light enough that humans were able to traverse the surface without any trouble, and it possessed a breathable atmosphere. Desertion of the Dinobots, Part 2 Water, or at least a substance resembling it, was in evidence on the planet—lakes and rivers have been shown to exist, albeit sparingly. Grimlock's New Brain War Dawn Many levels below the surface was the energy-furnace, the Plasma Energy Chamber, The Rebirth and at the heart of the planet was the spherical mega-computer, Vector Sigma. The Key to Vector Sigma, Part 1

LOOK HOW LOUD I HAVE TO YELL!

Cybertron was orbited by at least three unnamed moons, but its own place in the cosmos appears unfixed—in 1984, it was clearly shown to exist outside of the Milky Way; on the cusp of an entirely different galaxy, in fact. Roll for It Nine million years prior, however, Starscream and Skyfire had been able to fly from their home planet to Earth under their own power, Fire in the Sky suggesting that it may drift freely through space, and had been passing through the Sol System at that point, going on to drift out of the galaxy over the ensuing millennia.

If the assorted colourful exclamations made by numerous Transformers are anything to go by, Cybertron also played host to a vast array of fauna, including but not limited to: Antroids, bolt-bats, cyber-ducks, dynametal ducks, electro-toads, glitch mice, guinea pigatrons, helio-hamsters, hydro-weasels, photovoltaic pussycats, pidgeonoids, retrorats, robo-rats, sheepacrons, titanium moosebots, turbofoxes, zap-mice and robotopossums.

Twelve million years ago, the Quintessons used Cybertron as a factory to manufacture their robot creations. Notably, the origins of the planet are never explicitly stated—the Quintessons may have built it, terraformed an organic world, or colonized an existing metal planet. Whatever the case, after a million years, the Quintessons were forced to abandon Cybertron when their robots evolved true sentience and feelings, and knew they were being used as slaves, rebelling in the First Cybertronian War.

Though the early Cybertronians were able to successfully drive their cruel masters offworld, this new peace was short-lived; "consumer goods" robots developed into the peace-loving Autobots, while "military hardware" evolved into the warmongering Decepticons, and the two factions went to war. With the Autobots' innovation of transformation, they were able to win—or at least stalemate—the war, and a period of peace descended on Cybertron, which shone with a healthy golden glow, distinguishing the period as the "Golden Age". Five Faces of Darkness, Part 4

Eventually, however, Decepticons adopted transformation as well, along with robot mode flight, and around nine million years ago, the creation of the Decepticon Megatron re-ignited the war on Cybertron. Megatron rallied like-minded individuals to his cause, and brainwashed others into his service, quickly killing the current Autobot leader in a strike on one of Iacon's outer cities. With this act kept out of the public knowledge, rumors circulated as Autobot machinesmith Alpha Trion worked diligently on a new process to reconstruct Autobots into battle-hardy configurations for the war he knew was coming. That war finally erupted in full when Megatron fatally injured a naive young dock worker, Orion Pax, and Alpha Trion made him the first subject of his new process, reconstructing him into Optimus Prime, who would lead the Autobots in the Third Cybertronian War. War Dawn

The white zone is for blasting Autobots only.

After a further five million years of war, during which many Autobots fled the planet, the Decepticons had acquired a large hold on the planet, with the majority of it under their control. The main Autobot force continued to operate from the capital city-state of Iacon, but Cybertron's energy levels were depleted to a dangerous low, necessitating a space mission to locate a new planet with new sources of energy that the Transformers could harness. Optimus Prime led his best and brightest on the Ark, but they were pursued by Megatron's elite troops, and all were stranded in stasis on Earth for four million years. More than Meets the Eye, Part 1

In the ensuing four million years, Shockwave, who Megatron had left in charge as guardian of the planet, maintained the Decepticon hold on the planet, though he was unaware of the continued guerrilla efforts of Elita One's Female Autobots to undermine him as they raided his energy supplies. The Search for Alpha Trion Eventually, Cybertron's energy level dipped so low as to put the planet in immediate, mortal danger. Reestablishing contact with Megatron, who had awoken with the other Transformers on Earth in the year 1984, Shockwave co-designed the space bridge, an intergalactic transport system that could transport energon cubes from Earth to Cybertron, abating the planet's impending doom. Transport to Oblivion

I see a Cybertron a-risin'. I see trouble on the way.

Cybertron's place in the universe was forcibly altered in 1984 when the Decepticons constructed a colossal space bridge that actually transported the entire planet into the Sol system, into Earth's orbit,The Ultimate Doom, Part 1 where its gravity wreaked havoc with the planet's natural balance, unleashing an unending torrent of energy created by natural disasters. The Ultimate Doom, Part 2 The energy acquired re-energized Cybertron enough to put it out of the danger zone, but the planet was soon knocked out of orbit by a massive energon explosion, and set drifting off through the solar system. The Ultimate Doom, Part 3 At this closer range, Cybertron remained easily accessed throughout 1985 at least, with the Autobots now able to reach it by conventional transportation (Omega Supreme), rather than having to constantly hijack use of the spacebridge. The Key to Vector Sigma, Part 1

By the Earth year 2005, Cybertron had exited the Sol system, but, remaining within the Milky Way, was still relatively easily accessible by shuttlecraft from Earth. By this time, the Decepticon forces had succeeded in conquering the entire planet, forcing all the Autobots off it, leading them to relocate to Autobot City on Earth, and to two staging ground bases on two of Cybertron's moons. It was at this time that Cybertron came under attack from the world eater, Unicron, who consumed the two moonbases and assaulted Cybertron itself, only to be destroyed by the power of the Autobot Matrix of Leadership. His deactivated, decapitated head fell into orbit around Cybertron, a grisly new satellite to replace those he had destroyed. The Transformers: The Movie With the Decepticon forces in disarray after Unicron's attack, Rodimus Prime and his troops succeeded in driving their foes off Cybertron, reclaiming the planet for the Autobots, and restoring and re-energizing much of the planet by 2006, Five Faces of Darkness, Part 1 when the world came under frequent attacks from the returning Quintessons, whose previously-secret history with the Transformers came to light. Five Faces of Darkness, Part 5

In the year 2007, Cybertron was once again wrenched from its place in space when Galvatron and the Decepticons invaded the planet and constructed a massive planetary engine that propelled Cybertron back into Earth orbit once more. Once there, Galvatron opened the Plasma Energy Chamber, intending for the energy release to drive the Sun supernova, consuming Earth, Cybertron and everything else in one final destructive blow. Spike Witwicky and the Autobots' Nebulan allies were able to stop this plan by reversing the rocket engine, which drained off the excess solar energy and channeled it straight into Vector Sigma, which used it to fully re-energize Cybertron. Its rich golden hue restored, Cybertron entered a new Golden Age. The Rebirth, Part 3

The events of the Generation 1 cartoon occur in Japanese cartoon continuity as detailed above, except that the events of "The Rebirth" do not occur. Japanese continuity inserts several new stories into the timeline, including an extensive 2007 retcon that revealed the complicated origins of Cybertron in this continuity.

"It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree."

12 billion years ago, the ancient genius Primacron and his assistant, the Oracle were attacked by Primacron's renegade creation Unicron. The Oracle's body was destroyed, but his essence, encased within a protective shell, fled to a dead planet at the center of the universe, which he proceeded to transform into a verdant, living world.

In time, the Quintessons discovered the Oracle's world and invaded, taking control of the Oracle and his powers. The Oracle was transformed by the Quintessons into the mega-computer Vector Sigma and also obtained the shell that had held his essence, which went on to become the Matrix of Leadership. Using the power of the Key to Vector Sigma, the Quintessons transformed the Oracle's green planet into the metallic Cybertron. 2007 TakaraTomy Transformers timeline



The Headmasters cartoon

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—permanently tilted in favor 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. Eventually, this forced Optimus Prime to sacrifice his life by merging with Vector Sigma in order to stabilize the computer before it destroyed Cybertron from within. Four Warriors Come out of the Sky The Mystery of Planet Master Birth of the Fantastic Double Prime

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, and so, to prevent either him or the Autobots from obtaining it, arranged for his Headmasters to plant bombs at the core of the planet, within Vector Sigma's chamber. The Autobots were unable to stop the countdown and the bombs detonated, tearing Cybertron apart and leaving it a charred uninhabitable ruin drifting in space.

Following the conversion of Cybertron into a technorganic planet, Vector Sigma also underwent an upgrade and effectively turned into the "soul" of the planet, becoming the ultimate authority of the planet who issued its will through the newly created Convoy Council. Tens of thousands of years later, when Vector Sigma discovered that the Blentrons were trying to resurrect Unicron with Angolmois Energy, the supercomputer converted Cybertron back to a wholly mechanical planet in preparation for war.

The second Golden Age of Cybertron came to an end in 2013 when Jhiaxus initiated the Machine Wars. However, the Machine Wars ended in a matter of weeks and inadvertently brought about the signing of the Pax Cybertronia. Termination A Common Foe

In 2984, the Star Seekers arrived from a temporal journey through transwarp to enact Captain Cannonball's newest scheme: plunder Cybertron of all its energon using Unicron's head when Cybertron would be at peace and have high levels of energy. The pirates attracted the attention of Cybertron's elite defenders, the Cybertronian Knights, but during the clash aboard Unicron's head, Alpha Trizer gave Cannonball a crushing revelation: his scheme was doomed to fail from the start because the Cybertron he was attacking was technorganic and no longer ran on energon (as a result of the Great Reformatting). Hoist the Flag





A Birth of Planet Saybertron

Cybertron was originally a mere satellite, built to ensure peace between a coalition of planets. But the powerful computer within the satellite proved too advanced for it to remain in its initial form; using electromagnetic forces to draw in other satellites, it used their materials to build itself up. This ultimately led to a malfunction of the computer, and the civilizations that had built it found themselves no longer able to access it. Though the united civilizations tried to stop the satellite, it kept on growing and becoming more sophisticated, eventually plundering all nearby resources and leaving its galactic neighborhood bare of resources. Ages passed and Cybertron became a planet proper, with metallic mountains and oceans of oil. From it sprung primitive machines, which evolved into Transformers over the millennia. A Birth of Planet Saybertron





Beast Wars cartoon continuity

Eons ago, Cybertron was a verdant, Earthlike world, populated by a wide variety of organic creatures. Survivor This idyllic period came to an end when the first Transformers arrived on the planet, an event foreseen by the mystical Oracle that surrounded Vector Sigma; The Reformatting their arrival evidently coincided with the extinction of Cybertron's natural biosphere, Survivor and over the eons Cybertronian civilizations would build over the rock and soil with metal upon metal, giving rise to the illusion that Cybertron was, and always had been, a world of technology alone. The Reformatting Remnants of the past persisted in the lowermost levels of the planet, including stray plant life, Forbidden Fruit fossilized remains of the animals that had once roamed the surface, Survivor and an "organic core" composed of concentrated biological matter.

At least it's finally trying to keep an orbit.

Three hundred years after the end of this conflict and the signing of the Pax Cybertronia, The Agenda (Part 1) Cybertron would come to be populated by the Maximals and Predacons, descendants of the Autobots and Decepticons. This great metamorphosis was precipitated by the "Great Upgrade," described as the period of time when Cybertron's Autobot population transitioned to Maximals; old cities like Iacon were once again abandoned and paved over to make way for new cities, like Cybertropolis. The Search Three hundred years after the end of the conflict, Cybetron was once more a peaceful, prosperous planet, governed by the Maximal Elders, Possession while the Tripredacus Council controlled the affairs of the Predacons.

When Optimus Primal and his starship went missing, transwarp probes were dispatched from Cybertron in the hopes of finding where he and his crew had vanished to. The Probe Not long afterwards, the transwarp wavefront generated by the destruction of the Planet Buster superweapon was due to hit the planet only for the Tripredacus Council to disrupt it before it reached Cybertron, allowing them to covertly dispatch Ravage to bring in Megatron. The Agenda (Part 1)





Beast Machines cartoon

The tranquility of this age would come to a rapid end when Megatron returned from the Beast Wars and set a virus loose on the world that incapacitated the population and paved the way for Vehicon rule. Under Megatron's reign, the villain sought to reorganize the entirety of Cybertronian civilization into one vast machine controlled by a single, overriding intellect—his own. Master of the House Megatron would be opposed, however, by Optimus Primal and his band of Maximals, who, after discovering the Oracle, befriending a survivor of Megatron's attack, and learning the truth behind Cybertron's organic nature, Survivor believed that they needed to restore the organic to Cybertron and destroy all technology—a conflict that came to a head when Primal and Megatron pitted the Plasma Energy Chamber against the Key to Vector Sigma, unleashing a doomsday energy storm. End of the Line

In the aftermath, Primal realized he had been wrong in his mission; rather, the Oracle wanted him to create a balance, a peaceful equilibrium of the organic and the technological. In the end, Primal would see his dream accomplished when he applied the power of the Oracle to the exposed organic core of Cybertron, his sacrifice converting the entire planet into a lush paradise where technorganic plants and animals coexisted with Transformers. Seeds of the Future





3H comics

According to Al-Badur, the Quintessons had once served Unicron, and in doing so, they'd found the "dimensional landing" of Primus: Cybertron. Rather than alert their master, however, they decided to capitalize on their discovery for their own purposes. They attempted to subvert Primus's creations via the Plasma Energy Chamber, but the results were disastrous. Success came when they placed a shell program over Vector Sigma and channeled the divine power into creating a subservient race. That race would one day rebel and become the Transformers, but the Quintessons' influence remained in the form of the Vector Sigma shell program—otherwise known as the Oracle. Primus could nonetheless sometimes send messages from Vector Sigma through the Oracle, but it is difficult to tell the difference. Disclosure

A week after the Great Reformatting, the Quintessons invaded Cybertron, hoping the sudden transition to technorganic would leave the Transformers disoriented. Instead, the population of Cybertron successfully repelled the invaders—and the Quintessons learned that they themselves had been pawns of Primus, who had deliberately manipulated the aliens so that Cybertron and his creations could make this great evolutionary leap.

Dreamwave Generation One continuity

"They lied to us. Founding fathers of Cybertron. Everything we were told was a lie. Built on the lie of the sparkless child."

The planet Cybertron and its two moons orbited Alpha Centauri; a Saturn-sized mechanical world, the planet possessed an oxygen-based atmosphere capable of supporting carbon-based life. Complex tunnel networks and advanced machinery existed in the deepest levels of the planet; some Decepticons, like Megatron, believed that Cybertron could become a mobile fortress equipped with planetary engines, and sought to make this dream a reality. Transformers: More than Meets the Eye

The earliest Cybertronians supposedly arose from the Well of All Sparks, Conflagration but after creating the Transformers, Primus went dormant so as to avoid the attention of his ancient nemesis Unicron. The Sonic Canyons that spanned the planet's southern equator gathered data from across the universe so as to be analyzed by Vector Sigma, Transformers: The Ultimate Guide while Primus sealed the well to prevent Unicron from locating his physical form. Conflagration Prior to the Great War, Megatron claimed to have discovered an artifact which suggested the truth behind the origins of the Cybertronian species, which would, over time, lead to the formation of the Decepticons. The Route of All Evil

The war between the Autobots and Decepticons would eventually lead to Optimus Prime and Megatron disappearing in a space bridge explosion; in their absence, however, the conflict continued, with Autobots, Decepticons, joined by various splinter factions. Fragmentation. The arrival of The Fallen briefly forced these competing factions to briefly work together, Conflagration and dwindling fuel supplies eventually led to the construction of energy-efficient Micromasters—though these warriors were eventually forced to take up arms as well.

Everyone died, the end.

3.5 million years ago, continued energon shortages finally culminated in the event known as the "Great Shutdown," where all Transformers on the planet simply ground to a halt after Cybertron's natural supplies of energon completely dried up. This state of affairs lasted for many millions of years; it would not be until some three thousand years ago that Shockwave reactivated and worked to bring other Transformers back online. Cold War

Initially, after Cybertron's reawakening, Autobots were reluctant to trust Shockwave until key Autobots agreed to share leadership of Cybertron with him. An underground resistance movement was formed and a young Hot Rod rose to leadership of one such faction. It wasn't until Optimus Prime's return to Cybertron that the majority of Autobots rededicated themselves to eliminating the Decepticons. War and Peace





G.I. Joe vs. the Transformers

The Quintessons created both transorganics and the gladiator and slave races that would evolve into the Decepticons and Autobots. The Art of War #1

Following Optimus Prime and Megatron's crash on Earth, Cybertron was conquered by Shockwave. The planet was also the location of Teletran 3, which accidentally transported members of G.I. Joe and Cobra to the alien world. G.I. Joe vs the Transformers #1

Shockwave was eventually defeated and the Decepticons were driven back to the Gladiator Zone, allowing Cybertron to be at peace for the first time in millennia. A warp gate was set up between Cybertron and Area 52 on Earth.

2005 IDW continuity

Cybertron and its two moons orbited a yellow dwarf.[1] A Sunrise Dark The precise origins of the planet are not known; various religious sects held that the planet had a relation to Primus, who either arose from the surface of Cybertron Primus: You, Me, and Other Revelations or had himself created the mechanical world, Timeline in Revolutionaries #1 perhaps after vanquishing the mythological Unicron at the dawn of time. Last Stand

Another theory postulates that Cybertron may have once been an organic world, one whose biological inhabitants made an evolutionary leap to a cybernetic existence before eventually discarding their organic heritage to become fully-mechanical lifeforms. Spotlight: Nightbeat Evidence for this theory is corroborated by the planet Gorlam Prime, whose inhabitants underwent such a transition; after emerging from this "chrysalis state," they renamed their world "Cybertron," which raises some interesting questions about the origins of the Transformers. Spotlight: Sideswipe

The first known Cybertronian to come into existence was Primus himself; though later Transformers would deify him as a warrior-god, Primus: You, Me, and Other Revelations Primus's only unique trait was the ability to manufacture photonic crystals. He would be joined by four other Transformers—Epistemus, Mortilus, Solomus, and Adaptus—and together this first generation of Transformers would become known as the Guiding Hand. The Unremembering Together, they would go on to ignite the twelve hot spots across the planet, allowing Vector Sigma to begin sending the life-giving pulses of energy that ignited new sparks and gave rise to the first true "generation" of Transformers: the Knights of Cybertron, who turned the prehistoric planet into a paradise for both body and sprit. The Death of Optimus Prime The predecessors of Functionist doctrine believed that, if tilted at just the right angle, Cybertron could refract the light of a sun, turning the planet itself into a weapon to be used against asteroids and other spaceborne threats. Farsickness

Some twelve million years ago, the ambitious Adaptus would turn on his comrades; seeking to introduce the notion of war to the species so as to avoid the stagnation he feared would soon grip the planet, he battled the other four members of the Guiding Hand in what would come to be called the "God War". Although the other members of the Hand fought back, they were unable to vanquish their enemy, who fled to the planet's first moon, readying an electromagnetic pulse that would leave the inhabitants of Cybertron disoriented while he retrofitted the moon into a primitive spaceship and fled. The Unremembering Though this information creep would distort reality into garbled legends, the Knights of Cybertron remained known, and eventually opted to leave Cybertron aboard a fleet of Titans. Deprived of their benevolent oversight, Cybertronian society regressed back to an era of barbarism, splintering into numerous smaller city-states and tribes. The Crucible This sequence of events would be noted as atypical compared to the development of most other civilizations, who established permanent world governments before mastering faster-than-light space travel. Shining Armor #3

It was in this primitive landscape that the Decepticon Shockwave found himself after the destruction of his chronal drive in 2013. Unable to return to his own time, Shockwave slew the shepherd Onyx and manipulated events to bring the Thirteen together. The First Who Was Named In his new role, "Onyx" encouraged expansion and the colonization of distant worlds. Titans colonized distant worlds to expand the aegis of the Pax Cybertronia, including Caminus, Eukaris, Velocitron, and Devisiun, all in service to Shockwave's infinitely longer game. First Contact Eventually, Shockwave would also mastermind the First Cybertronian Civil War, Heavy The Crucible which ended in the ascension of Nova Prime and a grand reordering of the planet's society under Functionist doctrine. The Crucible It quickly became clear, however, that Cybertron's rapidly urbanizing population was not infinitely sustainable, prompting the younger version of Shockave to begin a plan to ensure that Cybertron could meet its energy needs; Shockwaves while Nova Prime planned a grand Expansion that would see Cybertron the capital of a grand interstellar empire, this plan fell through when he and his innermost retinue vanished aboard the Ark-1 in the Benzuli Expanse. Spotlight: Galvatron

The reign of Nominus Prime saw the widespread automation of Cybertron's old energon mines, leading to an employment crisis as labourers lost their livelihoods. Megatron Origin #1 Antebellum Cybertron was seen as a backwater placed by alien civilizations, owing to the cultural stagnation Functionism brought to the planet. Chaos Theory Part 2

The subsequent Great War began four million years ago, and ravaged Cybertron until Thunderwing's experiments with Pretender technology led to a mad rampage that left the planet completely uninhabitable. With no atmosphere, Cybertron's surface was unprotected from cosmic radiation and was wracked by plasma storms. Transformers had to divert energy to their personal shielding in order to remain on the surface for short periods; the surface was presumably immediately lethal for humans. Gravity was also weaker than normal and Transformers needed magno-treads to walk on the surface. The Transformer race abandoned the planet (save for occasional scientific surveys from orbit) and began conducting their conflict across the galaxy. According to Autobot command directives, landing on Cybertron was forbidden. Stormbringer #1 However, with the resurrection (and subsequent defeat) of Thunderwing, this directive was lifted due to the unusual circumstances. Spotlight: Galvatron

Around the year 1997, the wise Alpha Trion and Metroplex returned to Cybertron, with a plan to revive the planet. Over the next few years, Trion worked to repair Cybertron's atmosphere and rid it of radiation, though the planet remained dead and resourceless. Any Old Iron

It was after the apocalypse. No one was prepared... for the Robot Holocaust.

A decade later, the Decepticons created the three Insecticons on Cybertron from a naturally-occurring subterannean species, Historia, and left the thousands of failed clones to their own devices. When the Decepticons defeated the Autobots on Earth during the Surge, they sent their battered enemies through a portal to Cybertron, where the swarm would finish them off. All Hail Megatron #7 By this time, Alpha Trion's hard work had eliminated much of the radiation and electromagnetic storms, so the Autobots survived their stay on the planet with only minor pains. Any Old Iron Later, the Autobot starship Trion was shot down over Cybertron, and its crew joined the rest of the survivors on its surface. All Hail Megatron #5 They were eventually rescued by Omega Supreme, leaving Alpha Trion and Metroplex to continue their work uninterrupted. All Hail Megatron #10

In order to make Cybertron habitable again, Trion revived Ironhide, who had been recently slain on Earth, to help take out the swarm. Ironing Out the Details Trion then left again, with only Ironhide, Sunstreaker and a few hundred swarm members remaining on the planet, Any Old Iron which were eventually quashed by the time that Galvatron returned to Cybertron, intent on turning the metal world into his first line of defense against D-Void, a malevolent entity set on devouring all Transformers. Heart of Darkness #4 By the time his army arrived on the planet, the swarm had seemingly been exterminated. The arrival of Galvatron caused Ironhide and Sunstreaker to flee on Rodimus's newly arrived ship, after which they traveled to Earth to alert the rest of the Autobots to Galvatron's occupation. Out of the Silent Planet

Led by Optimus Prime, the Autobots on Earth returned to Cybertron and confronted Galvatron. Lamentations During the battle, Galvatron inserted his Heart of Darkness into the remains of Vector Sigma, in the belief that this would stop D-Void from entering the universe. In reality, the Heart of Darkness was an aspect of D-Void, and doing so would allow the entity to turn the dead planet of Cybertron into a giant portal to the Dead Universe. To stop this from happening, Optimus Prime opened the Matrix of Leadership into Vector Sigma. Genesis Somehow, the Matrix of Leadership was able to restart Vector Sigma, and its energies worked to "reset" the entire planet into a primordial state. Almost every structure and geographic landmark on the planet was wiped out, and the only Transformer-made structure remaining was the crashed remains of Kimia Facility. Simultaneously, Cybertron itself sent out a signal to all Cybertronians out in space, telling them to come home. The Death of Optimus Prime The only known structures that were spared this reformatting were Crystal City, resurrected by Ore-14, Shockwaves and Kaon which had been buried beneath the new layer of metal. The Last Autobot

With Cybertron restored, most Decepticons captured and thousands of neutrals returning to repopulate their planet, the war was considered over. When the planet came alive again, it began transmitting energy to its two moons, reviving Luna 2 as well. Since Luna 1 was missing, its share of the energy ended up in the atmosphere instead, supercharging it and causing "ball lighting" effects to strike the planet's surface until Wheeljack got a temporary satellite in orbit. Stick Together After a brief revival of the Autobot/Decepticon war, the neutrals kicked the two factions out of Iacon and briefly assumed control of the planet under the leadership of Starscream, Heavy Is the Head who established the Republic of Cybertron. The Sound of Breaking Glass

Soon afterwards, Shockwave attempted to bring his Regenesis plan to fruition, collapsing all of space-time into a singularity to fuel Cybertron for eternity which would have made the planet the sole thing that existed, had ever existed or would exist before he was defeated by Optimus Prime and Megatron. Dark Cybertron The destruction of his chronal drive caused the formation of a black hole that sent him back to the planet's prehistoric past, free to take up the mantle of "Onyx Prime" and shape the history of Cybertron in a great ontological paradox. The First Who Was Named

In the aftermath of the cataclysm, Metroplex was able to locate five of Cybertron's colonies, The Transformers: Windblade leading to the formation of the Council of Worlds, All That Remains which eventually came to encompass Earth after Optimus chose to annex the organic world into the Cybertronian Council for its own protection. Perihelion When Sentinel Prime abruptly returned to life, he viewed modern Cybertron as a world built on compromise; The Last Autobot disgusted, he planned to wipe the slate clean with an army of zombie Titans. Ten to Midnight Though he perished, Last Light the Titans arrived at Cybertron and began destroying all in sight Ping before they were stopped by Windblade and Vigilem. Rubicon

Earth would soon come to join the Council of Worlds as an official member state, not a mere protectorate, and various human dignitaries were shuttled from Earth to Cybertron via space bridge to prepare for the ceremony in Iacon. Unfortunately, repeated Cybertronian incursions had also convinced Joe Colton that one day Cybertron would destroy Earth, First Strike #1 and so he assembled an cabal of supervillains who would poison Cybertron's energon from within by harnessing the power of the alien Talisman, launching an all-out assault on Iacon while he and his inner team of supervillains travelled into the core of the planet to enact the plan. First Strike #2 Though Optimus Prime and his allies raced to stop the villains as they travelled to the core of Cybertron, it was soon revealed that the entire scheme had been masterminded by Colton's second-in-command; revealed as the Prysmosian wizard Merklynn, he used the Talisman to transform a small fragment of the planet into New Prysmos, a copy of his lost homeworld.

The process drained nearly half of Cybertron's energon supply which caused the planet to "scream", the missing energon sent into space as a communication signal that translated to "Welcome. Death". The signal struck the slumbering form of Unicron, and roused the ancient monster into action. First Strike #6 As Cybertron rebuilt from the invasion, "Onyx Prime" arrived alongside Liege Maximo and his Maximal hordes to put the final stages of his plan into action: Surfeit of Primes now convinced that Cybertron itself was not worth saving, "Onyx" revealed his true identity to Cybertron, engineering a series of crises designed to break the collective faith of Cybertron in everything that they believed in. Unforgivable Everything Shockwave had worked towards for the last twelve million years was in anticipation of Unicron's arrival: the very Talisman itself was poisoned bait; when Unicron consumed the planet, its corrosive energies would kill him from the inside out. Stranger Eons

In the meantime, however, the Talisman was still in service to the Visionaries who had recently come to inhabit the caverns beneath the planet, burrowing its way to Vector Sigma to complete its mission of transforming the entire planet into a copy of Prysmos. Schismatic To save the planet, Wheeljack constructed an anti-Talisman bomb that would counteract its magic, and when the bomb detonated, the exotic energies had the combined effect of transforming a patch of Cybertron into a copy of Prysmos's old biosphere, while also beaming a second message out into space: one that simply said "Unicron." Transformers vs. Visionaries Unstopped and Unstoppable

Indeed, Unicron awoke and began his assault on the galaxy not long afterwards, and after destroying eleven of the worlds affiliated with the Transformers Unicron attacked Cybertron directly. Stranger Eons Though the populace initially attempted to fight back, Our Finest Windblade was forced to call on the Visionaries, who used a combination of their magic and the Talisman to teleport the population of Iacon to Earth. Contrary to Shockwave's predictions, the destruction of Cybertron did not spell the destruction of Unicron; the planet-eater, intelligent enough to realize the threat that the tainted planet posed to his own body, simply destroyed the planet by tearing it apart, unleashing a burst of energy that ripped the planet in half. Road's End





The Functionist Universe

In a world where Megatron had never been created, the Functionist Council grew ever more powerful, to the point where they eventually usurped the Senate and functionally conquered the planet. The Custom-Made Now When the Council concluded that alien life had no purpose in Primus's grand design, they isolated their homeworld from the rest of the galaxy to stoke the fires of fear and xenophobia, while they worked to create an army powerful enough to wage war on the galaxy. Modes of Production

After the intervention of Team Rodimus cost the Council Luna 2, This Machine Kills Fascists the Council turned Cybertron itself into their instrument of destruction, outfitting it with a set of planetary engines and using the Warren to travel from world to world. The planet's lack of mobility proved a hindrance, prompting the Council to reengineer the planet so that it possessed a robot mode, cast in the likeness of the mythological Primus. With this new avatar, the Functionists were able to breach realities, and crossed over from their home reality to make war against the primariy timeline—an event briefly glimpsed by Adaptus, who had himself used the Warren to flee across time and space so as to prepare for the threat. Rationalizing that five Cybertrons, untouched by war, could command exponentially more power, he commissioned a planet-sized mold and created the "God Gun". Farsickness

Pursued by the dimensionally displaced Megatron and the Anti-Vocationist League back into Megatron's home reality, the Magnificence offered the suggestion to blow up Cybertron, though Megatron overruled it on account of the trillions of innocents still trapped on the planet. The Return of the King The crew soon deduced a way to overload Vector Sigma, preserving Cybertron while killing the Functionists. The Unremembering After forcing "Primus" back into planet mode, the crew allied with the Architect's forces to stage an invasion of Cybertron, battling Functionaries until they opened twelve duplicate Matrices at each of Cybertron's hot spots, the surge of energy overloading Vector Sigma and vaporizing the Functionists. A Spark Among Embers

With the native Cybertron recently annihilated by Unicron, this world—now stranded in a parallel reality—was eventually christened "New Cybertron" by those who chose to live there. Prowl made the decision to remove the Lost Light's quantum engines to double the universally displaced planet's energon reserves. With most of the Cybertronian population now based on Earth, New Cybertron was largely left to its own devices; in the years to come, the crew of the Lost Light took up residence there, while other inhabitants would include millions of Lunarians spawned from Luna 1's hot spot.

Transformers vs. G.I. Joe

Cybertron was the alternate mode of Primus, one of the many living worlds created by Daiakuron at the dawn of time. Earth: R.I.P. Though none of the inhabitants of either world were aware of it, Cybertron had a deep connection with the planet Earth, for the organic world was also a creation of Daiakuron, and Cybertronian artifacts from ancient times could be found across the planet. Everybody Hates Metroplex

Originally located in a distant galaxy, the planet had been ruled by Decepticons ever since the abrupt departure of Optimus Prime, leaving Megatron and his forces free reign of the planet, with the Autobots in disarray under Grimlock's unruly leadership. Form Follows Function When Starscream brought Bumblebee's head to Megatron, Megatron pronounced that the Decepticons had won the Great War, The Golden Boys and, binding the stolen Matrix of Leadership to his Spark, Pax Megatronus he subjugated Primus to his will via Vector Sigma. Cybertron then slowly began to transform into a massive spaceship in the shape of Megatron's face that would cyberform the galaxy. Expelled from the Garden Psych Out described Cybertron as "the ultimate Transformer" owing to its constantly shifting geography though whether this was a natural phenomenon or a side-effect of Megatron's plan is unclear. Form Follows Function

Cybertron then moved into Earth's solar system, I Saw Three Ships before it was invaded by G.I. Joe, using a combination of a "green bomb" fusillade and a strategically deployed Weather Dominator to terraform portions of Iacon into a an environment capable of sustaining human life. Targetmasters Soon after, Cybertron grew a pair of mega mountains that reached high into its atmosphere. Form Follows Function Megatron then used the horns to gouge into the Earth, seemingly destroying it Pax Megatronus so as to clear a path to the Sun, intending to consume the star and supercharge his creation powers. Escape from Primus Believing Earth to be destroyed, various surviving groups, such as the Oktober Guard, attempted to claim Cybertron as their new homeworld. Earth: R.I.P.

Starved of energy, Primus needed little incentive to consume the star, creating a dyson sphere from his own body to speed up its consumption before Primus was stopped by Atlas—Earth's own robotic form. Though many Cybertronians chose to emigrate from Cybertron to various planets and moons in Earth's solar system, Rodimus guided the impaired but functional Primus back to his original orbit. With Optimus on a mission to the find the Makers, Rodimus took charge of the planet. The War Never Ends





Beast Wars: Uprising

Cybertron orbits the star Hadean. Broken Windshields Following the Scouring of Nebulos in 2031 and the Great Push of 2033, the Transformers were forcibly pacified by the Human Confederacy and exiled back to Cybertron and a small region of surrounding space. After eleven million years of civil war, Cybertron had become a dying planet drained of energy, Micro-Aggressions and after a final battle against the maddened Thunderwing, who had absorbed the power of the Underbase, the war settled into an uneasy truce. The Autobots and Decepticons became known as the Builders and hard-wired themselves into the architecture and landscape of their planet as a means of saving fuel. Broken Windshields

Cerebros eventually constructed the Maximals and Predacons as successors to the old factions; the Builders, however, preferred to use them for sport in a series of violent Games fought in the ruined remains of the old Builder cities. Head Games At the same time, new breeds of Cybertronian life—mechanimals—began to emerge in the ruins of these old cities. While the older generations of Cybertronians considered them vermin, the Oracle had masterminded the process after the return of the Underbase to Cybertron's core as a means for the wounded planet to heal itself by generating a functioning, self-sustaining ecosystem. Derailment

This dystopian Cybertron was rocked by the Grand Uprising, a protracted war where the Maximals and Predacons fought to topple the stagnant oligarchy that their predecessors had established. Broken Windshields Shortly after the Beast Upgrade hit the planet, Overshoot claimed that the Oracle had also engineered this war, an evolutionary step forward that would free the citizens of Cybertron from their dependence on energon cubes. The war ended with the disastrous Vehicon Apocalypse, and although the Resistance had ostensibly won the war by that point, it took the united forces of Maximal, Predacon, and Builder alike to curtail the genocidal ambitions of Lord Imperious Delirious. In the end, the planet was reorganized under the egalitarian Cybertronian Parliament. Derailment

Years afterwards, as the Human Confederacy fell victim to the Fall of Man, the Cybertronian race ventured beyond the Allowed Zone once again. The Inexorable March While communing with the Oracle during the Grand Uprising, Overshoot glimpsed visions of the distant future, and saw a time when Earth and Cybertron would first unite against a grave threat before eventually merging into a single, technorganic planet. Cultural Appropriation

Of Masters and Mayhem

As the Great War continued, Decepticon science created Thunder Mayhem, a combiner so destructive that it was thought to have destroyed Cybertron outright and brought about the functional extinction of the Cybertronian race. Life Finds a Way History In reality, the combiner, while enacting a near-genocide, had simply devastated the planet's surface.

Left on Cybertron, Bluestreak eeked out an existence before he was contacted by the Teklaans who claimed that they could restore his world. Eager to bring about "New Cybertron", Bluestreak made contact with the Wreckers and brought them back home, sacrificing them to the Teklaans to provide them with the information they needed to rejuvenate the biosphere. As the prodding happened, Fractyl remembered that the Teklaans' last creation had fallen victim to a virus, implanted by the Teklaans themselves, and died off in a few generations. After convincing Bluestreak to aid them, the Wreckers confronted the Teklaans only to learn that the cyberforming had already begun. After incorporating Bluestreak and Impactor into Wreckage, the combiner destroyed the Teklaan ship, the central node of the cyberforming, and sent the aliens running. Upon leaving Cybertron, Impactor assured Bluestreak that his plan had been a good one but until Thunder Mayhem was defeated, it wasn't viable. Lively Pursuit

A living mechanical planet, The World In Your Eyes Part One Cybertron had been home to the Transformer race since the Age of the Firstforged, a primordial era that saw Halonix Maximus battle Preditron. Rise of the Decepticons: Tremors

Long ago, a group of Cybertronians once used the Enigma of Combination to become "The Abomination", a monstrous, fuel-guzzling combiner which ravaged the planet until a group of Transformers successfully felled the creature in Iacon. Constructicons Rising, Part 1 Over time, the Cybertronians established a planetary Senate led by a Prime, who served as the assembly's "First Senator." Constructicons Rising, Part 3

Eventually, the Cybertronian race began their Age of Expansion; as the Pyramid birthed many new Transformers, Constructicons Rising, Part 2 the people of Cybertron colonized new worlds with the assistance of many Titans and vanquished rival galactic powers. The Change In Your Nature Part Five But this prosperous age came to an end when one Transformer, Exarchon, was "corrupted" on a voyage away from Cybertron, and plunged his homeworld into the catastrophic War of the Threefold Spark. The war saw the mass conscription of many Cybertronians to stop the menace; although Exarchon's forces were defeated, the cost was high, and Cybertron was left broken and ravaged by the war. To limit further Cybertronian expansionism and help rebuild their planet, then-Autobot leader Nominus Prime passed the Nominus Edict, which forbade the colonization of other worlds, mandated strict laws regarding energon rationing and storage, and limited the forging of new Transformers. The Change In Your Nature Part Three

The ensuing era saw the rebuilding of Iacon, the construction of the Winged Moon to provide Cybertron with a limitless supply of energon, and the great Tether that connected it to Cybertron. Orion Pax: Free Fall Constructicons Rising, Part 1 While some Transformers looked back on the past with regret, noting that their expansion had caused other races to fear their destructive nature, The Change In Your Nature Part Five other Cybertronians like Termagax mourned a lost age of prosperity and potential that'd been cut short and felt that the Nominus Edict had overstayed its welcome. Orion Pax: Free Fall

By the time that Sentinel Prime supplanted Nominus Prime, Cybertron had established diplomatic relations with other neighboring powers such as the Thraal, Occulted Dremden, and Voin; Nautica: Home in time, different alien species immigrated to Cybertron and established various ethnic enclaves, such as Iacon's sprawling Xeno-Quarter. The World In Your Eyes Part Five They brought them with them animals like skitters and flyts, which turned invasive and established breeding populations on the metal planet. The World In Your Eyes Part Two

Termagax's "Ascenticon" movement grew to become a substantial political party that advocated for the abolition of the Nominus Edict in order to restart a new age of colonization and conquest; despite this sentiment, the Edict had indeed brought peace to the metallic planet, to the extent that Brainstorm's murder was the first in living memory.

Long before the Great War, Alpha Trion was a revolutionary leader who brought freedom to Cybertron, taking on Optimus Prime, Ultra Magnus and Megatron as his students. Siege episode 1 A great battle took place at Tarn-Hauser Gate, with it becoming the largest mass grave in Cybertron's history. Siege episode 4 The Autobots rebuilt Cybertron, Siege episode 5 before the Transformers began colonizing other worlds, such as Velocitron, travelling to them via Space Bridges. Siege episode 6

Under as of yet unrevealed circumstances, Megatron led the Decepticons into the destructive Great War against the Autobots. The Decepticons proved the superior fighting force, setting up Surrender Stations across Cybertron. Siege episode 3 As energon became ever scarcer, neutrals across Cybertron began hoarding and trading the substance among themselves. Siege episode 5

Outmatched, the Autobots constructed the Ark to flee their world. As they scavenged for enough energon to power the ship, they discovered the last Space Bridge. Siege episode 1 After learning that Megatron sought the Allspark to reformat all Autobots into Decepticons, Siege episode 2 the Autobots decided to launch the Allspark off the planet. Siege episode 3

After Bumblebee had inherited the Alpha Trion protocols, he used the information to pinpoint the Allspark's current location. Siege episode 5 Learning about the protocols, the Decepticons used Ultra Magnus' corpse to engineer a virus that destroyed them, though their similarity to Autobot code led to a widescale crippling of planetary infrastructure. Upon the Autobots retrieving the Allspark from the Sea of Rust, they managed to launch it through the Space Bridge, the Ark following shortly afterwards. A handful of Autobots, either by choice or circumstance, had remained behind, pledging to continue the fight against Megatron. Siege episode 6

In 2010, the unwitting Rad White activated one of the Mini-Cons which beamed a signal to Cybertron alerting the planet to the Mini-Cons' location. While Optimus Prime and Megatron led their inner circles to Earth to retrieve the Mini-Cons, the bulk of the Cybertronians remained on their homeworld to continue battle. First Encounter

After repeated battles on Earth, Megatron managed to slay Optimus Prime and obtain all three Mini-Con superweapons. The Decepticons set course back for Cybertron, followed by the Autobots. Depart Unicron however made his move prompting Starscream to sacrifice himself to unite the warring planet.

You DENTED it!

The conflict ended (again), the now predominantly Autobot and Neutral population began to rebuild their world. A further ten years later however, Primus's plan failed when the star collapsed into a black hole so powerful it not only threatened to consume reality itself but warped space/time, altering the past to an extent. Revelations Part 2 With the black hole hovering above Cybertron, Optimus gave the order to evacuate. Vector Prime returned to the planet for the first time in eons and revealed to Optimus that the Cyber Planet Keys were required to save their homeworld. Fallen Though Optimus was skeptical at first, he eventually made the search for the keys the top priority of the Autobots. Hidden After the Autobots had retrieved the Omega Lock and the keys from Velocitron, Jungle Planet and Earth, they brought them all to an altar deep beneath Cybertron where the energy of the three relics (bolstered by the Matrix of Leadership's energies) allowed Primus to transform to robot mode. Cybertron

After all four Cyber Planet Keys had been restored to the Omega Lock, Primus was restored to his full power which allowed him to close the black hole and save the multiverse. With peace now secured, Primus transformed into a new Cybertron which incorporated aspects of all four colony worlds. End

Movies

Bumblebee film

Wracked by civil war between the Decepticons and the Autobot resistance, it became clear to Optimus Prime that the Autobots could not hold out on their besieged planet forever, and ordered his Autobot soldiers to abandon their home and regroup elsewhere in the cosmos. One such warrior, the young Autobot B-127 was sent to scout out the planet Earth, which, eventually, became the temporary fallback position for other Autobot refugees from across the galaxy. Bumblebee





Transformers film

Hell on Cybertron. Image taken from New York skyline.

Cybertron was a world created by a device known as the AllSpark. With its power, it gave rise to the Transformers, but their civilization soon fell to war over control of the AllSpark—and when the AllSpark was jettisoned from Cybertron, both Autobots and Decepticons chose to pursue it into the depths of space.

Shortly after arriving on Earth, Optimus Prime showed Sam Witwicky and Mikaela Banes a hologram of Cybertron so as to highlight the ruthlessness of his ancient foe Megatron. Transformers





Revenge of the Fallen film

In ancient times, Cybertron was ruled by the Primes, a powerful race of Transformers who refuelled the AllSpark by extinguishing suns, constructing vast harvesters that would extinguish suns to refuel the life-giving device. When the Primes visited Earth 17,000 years in the past, however, one of their number chose to sacrifice Earth by constructing a harvester on the planetary surface. This, in turn, would lead to the sacrifice of the Primes, who sealed the Matrix of Leadership required to activate said machine in a tomb composed of their own bodies.

Dark of the Moon film

Honeycomb's big, yeah yeah yeah.

At the end of the Great War, Sentinel Prime attempted to leave Cybertron aboard the Ark, carrying a cargo of space bridge pillars; using these, he hoped, he would be able to teleport Cybertron to Earth, and plunder the resources of the organic world in order to restore his ruined planet.

Attempts to replicate the giant gash from Generation 1 have gone horribly wrong.

Though his plan would be delayed by the crash of his ship on Earth's Moon, Sentinel would reveal his alliance of convenience with the Decepticons in 2011, and attempt to teleport his homeworld into orbit. However, Bumblebee destroyed the master pillar before Cybertron could fully emerge from the portal, and the planet seemingly collapsed as it fell back through the portal. Dark of the Moon





The Last Knight film

Well, there goes the neighborhood... and that neighborhood. And that neighborhood. And that one.

Though Cybertron had survived its apparent destruction, the cataclysm left it condensed to a much smaller size than before (only slightly larger than Earth's moon) with several of its continents precariously attached to its core by large metallic cables. The sorceress Quintessa based herself on Cybertron, along with several Decepticon forces, and opted for a variation of Sentinel Prime's plan to restore Cybertron. Instead of draining Earth's resources to revive Cybertron, she would drain the life from Unicron (the core of the Earth) to revive Cybertron. To do this, she required a staff from Earth and Optimus Prime and thus sent Lockdown to retrieve the latter while she moved Cybertron into Earth's orbit. As the planet entered the Sol system, Optimus Prime crashed landed on it where Quintessa found him, brainwashed him and sent him back to Earth after she explained her plan to him. Cybetron's entry into the solar system caused Unicron's six horns to sprout from Earth's crust as the Chaos Bringer reacted to Primus' approach. Human scientists tracked Cybertron's approach and predicted it would collide with, and destroy, the Earth. Cybertron hid its final approach into the solar system behind the Sun, blinding the European Space Agency from tracking it before its trailing continents caused large gashes on the surface of the moon.

When Cybertron arrived in Earth's orbit, its continents slammed into the Earth and caused massive destruction. Quintessa and Megatron then began the ritual, draining Unicron's life force into Cybertron. Cybertron then began knitting itself back together, its continents reconnecting and the damage from the Great War vanishing as the planet began to regain its larger size. The Autobots and the TRF however managed to halt their efforts which left Cybertron in Earth's orbit. Enough of Unicron's life force had been transmitted to it that it had healed most of its damage and that Optimus felt it was time for all Autobots in the galaxy to return to their homeworld.

At the time of its partial restoration, Cybertron possessed notably organic landscapes such as grassy hills. As these were visible from space as the planet approached Earth, it is unknown if they were a natural part of the planet or if Cybertron collected this feature during its journey through interstellar space. The Last Knight

IDW movie comics

The AllSpark 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. Defiance #3 Defiance #4 Revenge of the Fallen #3

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, 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. Movie Prequel #1 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. Defiance #1 Defiance #2

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. Transformers A number of Transformers remained, with the Decepticons centered in Trypticon (now a Decepticon capital), but this didn't last long. The Reign of Starscream

Internally, Cybertron has similar features to the inside of a Transformer, including gyroscopic joints. Return to Cybertron, Part: 4

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. Training Day

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, Return to Cybertron: Part 1 which did enter Cybertron to renew it...

...and to everyone's horror, announced itself as Unicron, the Anti-Life! Return to Cybertron: Part 2

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. Return to Cybertron: Part 3 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. Return to Cybertron: Part 4

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. Revolution Part 2 Revolution Part 3



Shattered Glass

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 Cybertron never broke free of its orbit and continues to revolve around a sun. True to its backwards universe, Cybertron can be a frightening and arbitrary place whose natives are born from Omega Terminus and possess embers instead of sparks. Shattered Glass This Cybertron received a new satellite when the Earth of Primax 207.0 Epsilon entered its orbit as a result of the destruction of its home reality by Ultra Magnus's multiversal villainy. Invasion

Following the Shroud, Primus reawakened and assumed his robot form for the first time in eons, but had developed an evil personality as a result of ceasing being a multiversal singularity. Primus attacked the displaced Earth in his orbit but the planet fought back, revealing itself to be Primus's "sister" Gaea! Gaea was more than capable of defending herself and the Knights of Unicron helped her at a pivotal moment in the great clash, blinding Primus, and allowing her to obliterate her foe, destroying his body and thus the Cybertron of this reality. Only Primus's head remained, orbiting Gaea in her planet mode as she became "New Cybertron". The Future Buried...

Pointier than most.

The ancient world of Cybertron orbited the star Hadean, and was considered by the Autobots to be one of the most important planets in the Milky Way. Its true origins are unknown, though various theories suggested that it could have begun as a planet-sized factory, a product of atechnogenesis, or played a role in a clash between primordial titans. Chronometric dating suggests that Cybertron is approximately ten billion years old, with the earliest Cybertronian civilizations roughly eight billion years ago, a product of the mysterious, life-giving artifact known as the AllSpark. By six billion years ago, the Guardians and Malignus factions had colonized much of the Hadean system; by 750 million years ago, after the conclusion of the Third Cybertronian War, Cybertron had become the heart of a nascent interstellar empire that would come to be known as the Autobot Commonwealth as it underwent the Age of Expansion. The AllSpark Almanac II

The Great War between the Autobots and Decepticons began ten million years ago, when Megatron expressed his plan of using the Allspark to transform Cybertron into an "interstellar juggernaut". The AllSpark Almanac II The war razed Cybertron, The Thrill of the Hunt but the Autobots finally found a lasting advantage with the construction of the Omega Sentinels TransWarped Autobot mastery of space bridge technology and their strategic relocation of the Allspark led to ultimate victory, where the Decepticons were driven from the planet entirely; a unique departure from other fictions. Transform and Roll Out TransWarped Cybertron was once again dedicated to peace and an entire generation had seen neither armor-plating nor the transistor of a Decepticon. The AllSpark Almanac II

The Autobot culture under commander Ultra Magnus was primarily peaceful, although there was an organized militancy in the form of active boot camps Autoboot Camp. The ancient building Metroplex was home to the Autobot High Council and Guilds Domesticus, while the head of military operations was Fortress Maximus. The capital of Iacon was a major location, home to destinations such as Maccadam's Old Oil House, The AllSpark Almanac II and the abandoned Cyber-Ninja Dojo. Five Servos of Doom Cybertron and its citizens were very unfamiliar with and afraid of organic life. This Is Why I Hate Machines According to Sentinel Prime, it doesn't rain liquid on Cybertron; Where Is Thy Sting? despite this, it is has been shown raining. The Stunti-Con Job Make of this what you will.

Many stellar cycles later, a web of uncoordinated Decepticon attacks on the rim of the galaxy began taking place, in an attempt to claim control of the space bridges and TransWarp to the Spacebridge Nexus in Iacon, to wipe out the unarmed Autobot populace from within. Receiving wind of these attacks from a double agent on Cybertron, Megatron sent a transmission to the Decepticon cells and ordered the organizing of the attacks, Mission Accomplished and he himself began constructing a Space Bridge to lead his armies. Rise of the Constructicons

However, Megatron's space bridge was destroyed by the reactivated Omega Sentinel Omega Supreme. A Bridge Too Close, Part II The attacks were subsequently called off, much to the disappointment of the Decepticons who had managed to secure the bridges. TransWarped

When Megatron's double agent, Shockwave, sensed that his cover was about to be blown, he attacked Ultra Magnus, mangling the Autobot leader Where Is Thy Sting? and causing him to be put on severe life-support. This Is Why I Hate Machines This was not enough to save him, unfortunately, and he soon went offline. The AllSpark Almanac II Sentinel Prime, the acting Magnus, took advantage of the fear and paranoia created by the attack to grant himself emergency powers and aggressively remilitarize Cybertron, in an effort to combat the growing Decepticon threat.

However, Megatron, Shockwave and the other Decepticons immediately under his command were subsequently captured by the maintenance bot Optimus Prime and his team on Earth, Endgame, Part II where they were imprisoned in Trypticon Prison, part of the Decepticon City State of Kaon. A failed breakout attempt followed, with the Decepticons then diverting their attention to the (forceful) acquisition of Energon. The Stunti-Con Job

The Covenant of Primus

Cybertron was the mortal form of Primus, who, in aeons past, chose to enter into a deep hypersleep to as to avoid the depredations of his aggressive sibling Unicron. After Primus removed himself from the conflict, he created the Thirteen to fight in his stead, and the warriors successfully managed to defeat and exile Unicron, banishing his dormant body into a distant region of the galaxy.

Left to their own devices, the Thirteen began laying the foundations for a new society, only for the machinations of Liege Maximo to start the War of the Primes. The brief but violent battle concluded with the death of Solus Prime and the Liege Maximo, while Onyx Prime sustained mortal injuries and Megatronus exiled himself into deep space. Realizing that they themselves would need to leave Cybertron behind if the planet was to stand any chance of developing the remaining Primes hatched a new plan to populate the planet with a race of being based on their forms. Using a combination of Onyx Prime's Triptych Mask and the Well of All Sparks that had developed on the planet after Solus's passing, Vector Sigma itself was able to scan and gather data on all living creatures from across the universe and used that information to synthesize the first true generation of Cybertronian lifeforms: first, primitive bestial creatures, then the first humanoid Cybertronians—the Transformers themselves—and, finally, the Predacons. This era would later be known as the "Age of Evolution".

Early civilizations grew and thrived amidst this mechanical ecosystem, with the Thirteen defending these primitive villages against the aggressive Predacons, until Cybertron was menaced by the Great Cataclysm, which rendered most Cybertronian life, including the Predacons, extinct. In the subsequent "Age of Origins," the Cybertronian wilds would be tamed by increasingly sophisticated Cybertronian societies, with Azimuth and her Patterners responsible for reshaping vast swathe's of Cybertron's wilderness with the ritualistic astrological charts nessecary to predict another potential Great Cataclysm. It was in this state that Cybertron was discovered by the Quintessons, the rogue creations of Quintus Prime. The subsequent "Age of Wrath" saw Quintesson interference transform the planet into a spacefaring civilization almost overnight, installing Sentinel Zeta Prime as a puppet ruler while they manipulated the populace into an increasingly malleable and complacent state. As time went on, however, it became clear that the Quintessons had ulterior motives for the planet, and a Cybertronian rebellion that put their newfound transformational abilities to the test saw the Quintessons and their servants forced back offworld.

In their haste to flee the planet, however, the Quintessons had left their technology behind, and Cybertronians were able to reverse-engineer the principles behind space bridges. Using these devices, Cybertron began an age of colonization, the "Golden Age," settling worlds that included Archon, and Velocitron, cyberformed via a conversion beam. The prosperous Cybertronian empire collapsed when the Rust Plague hit, a virulent disease that corroded all metal it touched; recognizing that the space bridges allowed it to jump from world to world, Sentinel ordered them all destroyed, cutting off Cybertron from the rest of the galaxy.

The Golden Age over, Cybertron entered the "Age of Rust," a period marked by strict social stratification and the consolidation of power under an ever-increasingly corrupt and stagnant Senate. This moribund state of affairs ended when an outspoken gladiator named Megatron emerged, his words inspiring Cybertron to accept a new generation of change. Among those who heard his message was the archivist Orion Pax, but circumstances would drive the two friends apart, sparking the Great War that would ultimately see Cybertron poisoned by Dark Energon and rendered uninhabitable for millennia until the end of the war, when the planet was re-energized and reborn.

Transformers: War for Cybertron

When Megatron discovered the powerful substance known as Dark Energon, and that he could control it, he sought to use it to bring Cybertron under his control by infusing it into Cybertron's very core. Unaware of the true nature of the substance, the Dark Energon poisoned the planet. Though Cybertron's immune system initially fought back against the corruption, the spread proved too rapid and the planet was forced to shut down, Optimus Prime sending the Autobot fleet elsewhere in the galaxy to wait out Cybertron healing itself. War for Cybertron

Transformers: Rise of the Dark Spark

In Cybertron's prehistoric era, the early Cybertronians discovered the Dark Spark, purported to be the antithesis to the Matrix of Leadership. Unable to decipher the truth of its origins, or properly tame its terrible power, the artifact was locked away within Crystal City.

In the modern era, as Cybertron continued to shut down following the Dark Energon corruption, the Autobots and Decepticons clashed over possession of the Dark Spark, Optimus eventually managing to use the Matrix of Leadership to send the Dark Spark off of Cybertron. Rise of the Dark Spark

Transformers: Fall of Cybertron

As Cybertron entered the final stages of shutdown, Shockwave re-discovered space bridge technology, using it to find a distant, primitive world that possessed a rich enough energy supply to reboot Cybertron. When he opened up a space bridge to this world, the tower was attacked by the Dinobots damaging it and rendering the portal unstable. Taking the chance to get off-world, the Autobots raced for the singularity, the Decepticons following for the chance to destroy
