However, Unicron inflicted his mental torture upon Galvatron, forcing him to fight Hot Rod. Hot Rod took the Matrix from Galvatron during the battle, and became Rodimus Prime. Rodimus threw Galvatron into space, freeing the Decepticon from Unicron's mind-control, and opened the Matrix within Unicron, destroying his body, leaving only his head, which became a moon of Cybertron.

Marvel Comics

Far more than a mere product of science, as in the cartoon, Unicron was a fallen god from before the universe existed, who sought the ultimate peace that would be granted by the destruction of all life. Amazingly, Unicron accomplished this task, wiping out all life, planets, stars and nebulae, even "the stuff of space itself" in the universe and leaving only nothingness and void. His lust for destruction finally sated, Unicron entered a deep sleep - but he had not been thorough enough. Tiny fragments of the old universe reacted with each other, and a new universe was born. As Unicron slept, the core of this new universe - somehow a sentient being - became aware of Unicron's threat and created a defender to battle his evil - Primus

, the lord of light. Unicron awoke to find himself surrounded by another universe, and simply began to destroy it again.

He and Primus clashed many times, the force of their battles wiping out the very life Primus had been created to protect. To stop this physical destruction, Primus shifted the battle to the astral plane, where he fared little better, forcing himself into what seemed to be a sacrifice play - in shifting the battle back to the physical universe without time to properly generate their energy forms, Primus entrapped both himself and Unicron in two barren asteroids. But this was not the end of Unicron - over the eons, he learned to psionically shape his asteroid, and transformed it into a metallic planet, and then again into a gargantuan robot. Primus, fearing that to follow suit by forming himself in a similar manner would simply pick up the conflict where it had left off, sought an alternative way to defend the universe against the threat of Unicron by turning his asteroid into Cybertron

In the UK comics' version of post-movie events, Unicron's head did not enter Cybertron's orbit, and instead crash-landed on the Planet of Junk. Still active, Unicron used his vast mental powers to enslave the minds of the Junkion natives, who set about rebuilding his body. Cyclonus

, also fell prey to him, and he used them to exacerbate the stalemated war on Cybertron to keep the Autobots busy, so that they would not learn of his impending resurrection. When Death's Head fought back against Unicron's mental control, however, Unicron rewarded his temerity by revealing the comic book version of his origin. Death's Head then aided Rodimus Prime, projecting his mind into Unicron's where they battle, until Unicron's head was destroyed by explosives, and his essence was sealed within the Matrix. Rodimus and several other future Autobots subsequently traveled back in time to 1989 and participated in the "Time Wars", but when they attempted to return to their own time afterward, they discovered that disruptions to the timestream had erased their future, and replaced it with one where the Decepticons ruled Cybertron. In this dark future, Unicron's essence emerged from the Matrix and briefly took over Rodimus Prime, before he was thwarted by the removal of the Matrix from Rodimus's body. In 2010, however, Unicron attempted this again and succeeded, controlling Rodimus's body and reshaping it into his own image, before being defeated by Rodimus's own force of will.

 and the Decepticons' Mayhem Attack Squad at the centre of Cybertron had the unfortunate side effect of waking the slumbering Primus, who was struck by a stray laser blast and awoke with a scream. Although he immediately sank back into slumber, Primus's scream echoed throughout the universe, to the fringes of known space where Unicron heard it. Now aware of his old enemy's location, Unicron immediately headed towards Cybertron, but, seeking a herald to sow chaos in his name ahead of his coming, used his formidable powers to send three agents - Hook, Line and Sinker, forward in time to an alternate future version of 2009. In this timeline, Unicron had succeeded in consuming Cybertron in the year 2005, and Galvatron and the Decepticons ruled Earth. This timeline's version of Galvatron was pulled back to 1990 by Hook, Line and Sinker and press-ganged into Unicron's service, but, like his predecessors, turned on his master by forcing Emirate Xaaron to awaken Primus in hopes of destroying Unicron. Primus possessed Xaaron's form and attempted to hold off Unicron, but he was weak, and his attack was a ruse, leading to his own destruction, which in turn (along with a direct attack by Galvatron) succeeded in galvanising the Autobots and Decepticons to attack Unicron together. Ultimately, they did little damage, and many Transformers died, before Optimus Prime was able to use the Matrix to destroy Unicron, exploding his body from within.

It was not until 2003 that a production Unicron toy was made. For the 20th anniversary of the original movie, Diamond Select released an eight and a half inch tall statue of Unicron and Rodimus Prime.

The third season of the Transformers animated series continued Unicron's story from where the movie left off, as the planet-eater's deactivated head settled into orbit around Cybertron

Starscream demanded that Unicron restore his own body so that he could complete the required connections; but once Unicron had done so, Starscream, somewhat predictably, double-crossed him and refused to finish the job. Unicron's head was subsequently blown off into space by an explosion instigated by the Autobots.

Later, when searching for a new supply of positrons (anti-electrons), the Decepticons ventured to Unicron's head, where Cyclonus and Scourge accidentally awoke the slumbering demi-god. At the same time, Grimlock

, and one of their number, Strafe, severed enough of Unicron's neural connections to shut him back down.

Although Unicron himself did not appear again, his origin in the animated series was later revealed. Unicron was created near the beginning of the universe by the diminutive genius known as Primacron, who intended for him to devour all life in the universe, leaving a blank slate that Primacron could use as he saw fit. However, Unicron turned upon Primacron, deciding that he would rule the universe and subsequently setting out to achieve that goal.

Unicron's head was seen one last time as Primacron's new creation had crippled Cybertron. This time the head looked very old and almost stone-like, underlining that Unicron was finally dead.

When the Generation 2 animated series was aired, animated bits of the film with Unicron in it were edited into the episode "More Than Meets The Eye Part 1."

As with his original incarnation, there was a failed attempt to make Unicron into a toy for the Beast Wars Neo line, and although regarded as quite impressive, the prototype - which, notably, does not resemble Unicron from the Beast Wars Neo series at all - did not make it into the production.

This incarnation of Unicron was never shown to physically consume planets in the same manner as his G1 predecessor, only to blast and absorb the remains. However, during his battle with Optimus Supreme, who had grown to Unicron's size, Unicron demonstrates that he had enough power to simply destroy a planet completely without consuming it. However, several references were made to consumption, so he may indeed perform the action. For example, in one of the mini-comic books packed in with the later Armada toys, Unicron is indeed illustrated literally eating an asteroid or moon whole. This Unicron was voiced by Mark Acheson

A primal force of evil from the beginning of time, his origins lost to the mists of history, the Armada universe's incarnation of Unicron was the embodiment of the darkness and hate that lurks in the hearts of all beings. Having been defeated by the Autobot warrior Omega Supreme

 at some time in the ancient past of Cybertron, Unicron hid himself in plain sight of the Transformers, disguised as the planet's moon. In order to re-energise himself, Unicron implanted some of his own cells within Cybertron, where they grew and "hatched", giving birth to the diminutive race of robots called the Mini-Cons. It was Unicron's intent that these small robots would increase the ferocity of the Autobot/Decepticon war, allowing Unicron to feed off the hatred that the war fermented - but as a result of interference by human children, displaced in time from the 21st century, the Mini-Cons developed sentience, and fled Cybertron, crashing on Earth, where they lay dormant for a million years.

The subsequent awakening of the Mini-Cons once again increased the pace of the war, and to hasten the proceeding, Unicron created another being from his own body, Sideways, to serve as his agent for the purpose of constantly manipulating the events on Earth to keep the balance of power forever shifting, the ferocity of both sides constantly increasing. At the culmination of his plan, the Decepticons came into possession of all three Mini-Con weapons - the Star Saber, the Skyboom Shield and the Requiem Blaster - which Sideways and Thrust then stole and used to reactivate Unicron.

Shedding his lunar skin, Unicron transformed to robot mode and turned on Cybertron as the combined Autobot/Decepticon armada attempted in vain to stop him. Optimus Prime and Megatron (now Galvatron) entered his body with the human children, and Unicron addressed them through Sideways's form, absorbing all but Optimus into his collective consciousness and bringing the Mini-Cons back under his control. However, from within Unicron's mind, Rad was able to use his connection to High Wire to restore the Mini-Cons' individual minds, freeing the weapons and deactivating Unicron. With the danger apparently over, Galvatron challenged Prime to a final battle, but the hatred between the foes stirred Unicron to life again, and upon realizing this, Galvatron decides to sacrifice himself to make sure there will be no more hatred. Plunging himself into Unicron's maw and allowing Optimus to escape alive, Galvatron ended the hatred, and in a mighty flash, Unicron vanished without a trace although at the end of the series he was shown orbiting earth after the autobots dropped the kids off on earth

However, Unicron's body was inactive, badly damaged from his previous battle, and ten years after Galvatron's sacrifice a former victim of Unicron chose to strike. Within Unicron's shell, the Spark of Alpha Q, ruler of Planet Q, which Unicron had consumed in the past, still existed, and from Unicron's body he created the Terrorcon

. Hunted by Megatron, Alpha-Q then jettisoned Unicron's head and escaped in it, while Megatron took over Unicron's body and continued to gather Energon in order to rebuild Unicron to use as his ultimate weapon. As the climax of this plan neared, a joint attack by Alpha-Q, the Autobots and their human allies saw all of Earth's Energon channeled into Unicron's head, which Alpha-Q then rammed into Unicron's body. The positively-charged Energon of Earth reacted with the negatively-charged Energon running through Unicron, tearing open a fissure in reality leading to a new area of space where planets Unicron consumed were recreated and sustained through the Energon radiated from Unicron's head, which had now become a glowing red sun.

Unicron's body, damaged once more, lay in the dark reaches near the fissure, and the Decepticons began to raid Alpha-Q's new planets for the Energon necessary to revive Unicron again. This time, they succeeded, and Megatron directed Unicron's body to retrieve his head, extinguishing the Energon Sun and killing Alpha-Q in the process. But the power of Unicron proved too much for Megatron to control, as Unicron began to take over Megatron's body. In the ensuing battle Unicron's body was successfully destroyed by super-powered Optimus Supreme with help of some of the other powered Autobots. Unicron's body was destroyed - but unbeknownst to anyone, he lived on in two forms: his minuscule Spark, and his consciousness, which lay buried in Megatron's mind. With quiet, subconscious nudgings, Unicron led Megatron to a massive reservoir of "Super Energon" beneath Cybertron's surface, which transformed him into Galvatron upon his first exposure. After a series of failed battles, Galvatron proceeded to expose himself to the Super Energon once again, and this time grew to a gigantic height. Unicron seized control of his body again for a new vessel and set out to rejoin with his Spark, but a Primus

-empowered Optimus Supreme engaged him in battle once more, and drew all of Unicron's consciousness out of Galvatron and sealed it within his own Spark. Enraged, Galvatron prepared to destroy Unicron's Spark, but it merged with him, enlarging him again, leading to another battle with Optimus Supreme, this time bolstered by the combined energy of all his troops' Sparks. Meanwhile, Primus merged with the Super Energon, creating a foundling sun which arrived at the site of the battle. Taking control of his body for a brief moment, Galvatron once again sacrificed himself in order to stop Unicron, plunging himself into the infant sun, which ignited and gave new life to Alpha-Q's worlds.

 himself that destroying Unicron resulted in an imbalance between good (Primus, who still existed) and evil (Unicron, who was gone); this imbalance factored into the creation of the black hole, known as the Unicron Singularity in American fiction or the Grand Black Hole in Japan. His scattered pieces was absorbed by Megatron giving Megatron dark powers and causing him to look like Unicron.

However, the Japanese equivalent, Galaxy Force, made several scattered references to Unicron, as the Japanese producers for the series decided not to have Galaxy Force follow on from the events of Micron Legend (the Japanese equivalent of Armada) and Super Link (the Japanese equivalent of Energon).

Fun Publications

The Transformers club comic has further developed Unicron's story for the Cybertron era, attempting to fill in the plot holes. Clarification states that Primus' chosen task in Energon was to imprison and burn away Unicron's disembodied spark within a fledgling sun. This sun was the one that was born to save Alpha-Q's world. Unfortunately, Megatron's spark, also inside, interfered and the sun collapsed, trapping Unicron's spark inside (bridging it between other universes). The black hole was born, and Megatron was freed. He used pieces of Unicron to remake his body, as well as revive Starscream, his most loyal subject. The black hole itself has begun to devour space and time, unravelling historical events and building new ones. This is the reason for the "errors" in the Cybertron animated series, as it is following a constantly reshaping universe.

A new Unicron figure was released at the end of the Cybertron toy line as a Deluxe-class figure with a tank-like alternate mode. Although the character did not appear in Transformers; Cybertron or its Japanese equivalent Transformers: Galaxy Force, the Hasbro Club comic served to introduce this new version of the Chaos-Bringer. In this story, the black hole contains Unicron's essence and also links him simultaneously to all Cybertrons across the Multiverse giving him the potential to wipe out Primus in one fell swoop. This course is currently being held at bay by Transformers from across the Multiverse, usually consisting of characters derived from Convention and Club exclusives as well as Cybertron figures that play no role in the television series.

storyline as the presumed source of Dark Energon (the substance is also referred to as the "Blood of Unicron"), a form of Energon said to revive the dead. Unicron is also believed to represent the Anti-Spark (most likely a counterpart of the Allspark. In the episode "One Shall Fall", Unicron makes a cameo.

Unicron finally appears in "One Shall Rise, Part 1", voiced by John Noble. As Optimus Prime relates, Primus and the original Thirteen Primes banished Unicron from Cybertron. But as the Chaos Bringer drifted through space, he formed with various minerals to become the planet Earth, rich with Dark Energon. During the season finale, Unicron awakens as a planetary alignment brings him out of slumber. Megatron tries pledging his loyalty to Unicron but is refused. Angry that Megatron did not finish off Optimus, the last of the Primes, Unicron decides to finish the Autobot leader himself. He appeared to Optimus in a transformer-sized stone form. Optimus attempted to plea for the humans whom evolved on Earth but Unicron dismissed them as parasites. After Optimus seemingly defeated him, more stone constructs of Unicron emerge, emphasizing that he is planet Earth and can manipulate it to his own ends.

Megatron, angry that Unicron rejected him, sides with the Autobots at the moment Unicron would finish Optimus. Using the ground bridge and with Megatron's direction, they enter Unicron at the Earth's core. Optimus uses the matrix of leadership to send Unicron back into slumber. When it's done the energy of the matrix is drained, and Optimus loses all memory since becoming a prime and obtaining the matrix. He recognizes Megatron by his earlier name, "Megatronis" and himself as "Orion Pax". They leave together to the Decepticon base.

Across the multiverse

Although many of the official television and comics appearance of Unicron appear to present separate and distinct incarnations of the character, some writers have presented an interpretation of the sources that ties all the versions of Unicron together into a single continuity. Likewise, Primus is also a "multiversal singularity", but while Unicron is limited in this ability, and can only exist in one reality at a time, travelling between them, Primus co-exists in all realities simultaneously.

This concept began with the release of a series of Transformers: Armada trading cards by Fleer

, and the brothers set about this task, until they came upon a region of space teeming with pure Energon. Unicron wanted this power for himself, and cut Primus down before he could report it to the Allspark, casting his brother's body into the orbit of a nearby star. And so Unicron went on to become the engine of destruction that menaced the universe in recent years.

 cemented this notion. Writer Simon Furman incorporated the various aspects of the Dreamwave comics story, some elements of the Fleer storyline and his original Marvel Comics origin to create what is now essentially the "definitive" origin for Unicron. In this version of events, Unicron and Primus were again twin heralds, giant metal planetoids created by the "One", who were sent to explore the universe. But Unicron was an imperfect being and turned to evil, adapting his form to transform into a giant robot. To battle him, The One gave Primus this power also, but Primus opted to remain in planet mode, and passed the transforming abilities on to thirteen robots that he created from himself; the first Transformers. One of the thirteen turned on Primus and sided with Unicron, however, and the war culminated in a battle that saw Unicron and this traitor, the "Fallen

", sucked through a black hole into another universe.

This new origin is part of the G1 timeline laid down by the Ultimate Guide, which is apparently being taken as the "official" G1 timeline for future projects that require it. This means that there is only one Unicron who has travelled from universe to universe across all the assorted Transformers continuities. This interpretation of the character is evidenced by the parallel universe spanning Transformers: Universe

toyline and convention-exclusive comic books — in which the singular Unicron captured Transformers from various alternate realities and pitted them against each other, feeding off the energies released — and the Transformers: Cybertron comic strip in the Transformers Collectors' Club fan magazine, which depicts Unicron's actions in the various realities in a chronological order and claims that Cybertron is the stable heart of the Multiverse.

The idea of a singular Unicron and Primus remains the official take on the subject, despite any contradictions in other official Transformers fiction.

Physical dimensions

Unicron's size is never specified in any canon materials, aside from the vague term "planet size". In Transformers: The Movie, Unicron's height appears to be anywhere from several kilometers (as when handling Galvatron) to several hundred kilometers (as when attacking and destroying Lithone and Cybertron's moons, and attacking Cybertron

). A planet-mode diameter of 1000 km has been suggested and robot-mode dimensions would follow from that estimate, provided that there is no change in size (compression or expansion) common among so many Transformers. In fact, one scene in the movie shows Jazz driving out of one of Unicron's eyes, just small enough to fit through them, though in another scene the Quintesson ship Hot Rod arrived is tiny compared with the eye. Unicron is also small enough to stand on Cybertron's surface. In season 3, it is shown that the eyes from Metroplex

 (both city-sized Transformers) are the perfect size to use as replacement parts when Unicron orders the ghost of Starscream to steal them. However later in the episode when Trypticon moves Unicron's head, the head is larger than Trypticon's entire body. (Note: However, the eyes could be only small components for his Optic Sensors to be reformed and/ or completed.) In the storyline "The Ultimate Doom", Cybertron appeared to be smaller than Earth's own moon (and by extension, this would indicate Lithone would be too small to be a planet), making Unicron's dimensions in the cartoon harder to define.

). As Unicron's planet mode is seen to be as large as Cybertron (if not larger) in the comics, this would suggest a diameter of 120,000+ km. The Dreamwave equivalent of Unicron may be the same size, as the Cybertron of the Dreamwave universe was also said to be the size of Saturn.

The Transformers Prime iteration of Unicron depicts him as the center of Earth, making him a planet with sustainable life, though it has not been seen if Unicron wishes to consume other planets like his other incarnations.
