'''Unicron''' is the eternal arch-enemy of his twin brother [[Primus]]. He is known as the Dark God, the Chaos Bringer, the Planet Eater, and he is dedicated to consuming the multiverse. His goal is to bring an end to the annoying creation boasting independence around him, and find peace by becoming the living center of a [[Void|swirling, infinite torrent of nothingness]] at the end of all things.

To undertake this seemingly overwhelming task, Unicron is able to travel across realities at will, a meandering plague upon existence itself. <ref>Titanium Series 3" Unicron profile</ref> Integrated into his systems are incomprehensible quantum computers which calculate probabilities forward and backwards in time, in perpetuity, giving his processors an everchanging, evolving map of the multiverse.<ref>Profile, Transformers Fan Club newsletter, Aug/Sept 06</ref>

The only thing that he fears is Primus's essence, contained inside the [[Matrix of Leadership|Matrix]].

Frequently, Unicron will make deals with lesser beings, giving them vast new powers in exchange for their servitude. These minions are sometimes stripped entirely of their free will, but others follow him willingly. Service to Unicron, however, is a double edged sword, for it causes insanity and loss of self. And in the end, no matter their intent, Unicron's plans ultimately call for their consumption as well.

==In the beginning==
[[Image:UK150Unicron.jpg|left|200px|thumb|Saay, that shield looks [[Decepticon|familiar]].]]
Before the dawn of time, Order and Chaos existed within an extradimensional entity known as the [[One]]. To explore the fledging universe, he created the astral being known as Unicron, and then subdivided him, creating his twin, Primus. Both brothers were multiversal singularities, unique in all realities, but whereas Unicron could only exist in one dimension at a time, moving between them at will, Primus existed simultaneously in all realities at once. It is suggested, in fact, that the two brothers embody the basic concepts of reality—good and evil, order and chaos—and that their continued existence is necessary for the stability of the multiverse.

[[Image:Primusoriginal.jpg|right|180px|thumb|"No, [[Frenzy (G1)|Frenzy]] is ''[[RIBFIR|red]]!''"]]
As Unicron and Primus went about their appointed task, venturing through the cosmos, it became apparent to Primus that Unicron was a corrupt being, and he took it upon himself to stop the threat posed to all of existence by his sibling. In combat, Primus was no match for Unicron. In cunning, however, he proved himself to be his brother's superior when he shifted their battle to the astral plane, and then back to the physical world once more, only to have both their essences manifest within metallic planetoids, leaving them both trapped. It was with this act of sacrifice that Primus hoped to contain Unicron's evil forever. Unfortunately for him, over time, Unicron learned to psionically shape his prison into a giant metallic planet, and Primus followed suit, becoming the mechanical world of [[Cybertron (planet)|Cybertron]]. When Unicron then learned to transform his planetary form even further, into a gigantic robot form, Primus adapted the idea to suit his own ends, creating a group of [[13 original Transformers|thirteen robots]] that possessed the ability to change shape, like Unicron.

The war between Unicron and Primus came to its seeming end during a climactic battle in which one of the Thirteen, who would forever afterwards be known as the [[The Fallen|Fallen]], betrayed Primus and became an acolyte of Unicron. The battle ended when the Fallen and Unicron were sucked into a black hole and disappeared from reality. With Unicron gone for now, Primus entered an eons-long slumber, his self-imposed sleep preventing Unicron from detecting him through the mental link the brothers shared.

===Evolution of the Primus/Unicron myth===
''The Primus/Unicron backstory has evolved and been rewritten a good number of times since it first originated in the [[Marvel Comics]] series. The version recounted above is the current iteration, which has slowly solidified across a wide swath of media (beginning around the time of [[Armada (franchise)|Armada]]). Before the Primus/Unicron mythos reached its present form it went through several distinct versions in the Marvel G1 comics and elsewhere.''

====Unicron's story====
''The first time we ever heard the Primus/Unicron backstory was in the UK comic continuity, from Unicron himself, in the story "[[The Legacy of Unicron!]]", when he recounted it to [[Death's Head]]. Per Unicron's telling of events, he was a primal force of evil at the dawn of the universe, who led a legion of [[Dark Armies]] against his mortal foe, Primus, Lord of the [[Light Gods]] (note the plural). Events proceeded to play out basically as described above, though the role of the Light Gods and Dark Armies would diminish with each subsequent retelling of the story, until the current version, in which Primus and Unicron are alone, and have a unique origin.''

====The Keeper's story====
''The second time the story was told was in the US book by the [[Keeper]], an ancient mechanoid who guarded Primus's head at the center of Cybertron. This telling is effectively the same as the previous UK story, but mentions that their battle was towards the end of the era of gods, that Primus and Unicron were the last of their respective pantheons, and Primus had to defeat Unicron before he could take his place with the other gods in the "[[Omniversal Matrix]]".''

====Primus's story====
''The third time the story was told was also in the US Marvel series, this time by Primus, when he gathered all his children together to prepare for Unicron's coming. It was with this telling that we learned that Unicron predated the current universe, and had destroyed the previous universe which existed before the current one. He had slept peacefully, alone in the void of uncreation that remained, until fragments of the old universe that he had overlooked reacted, causing the Big Bang and birthing the current universe. The "sentient core" of this new universe recognized the threat that Unicron posed, and so created Primus to counter his evil and be guardian of the new creation.''

====Fleer and DK====
''The first modern retelling of the origins of Primus and Unicron did not come from G1-oriented media, but from a set of ''[[Armada (franchise)|Armada]]'' trading cards released by Fleer. It was the backstory printed on Unicron's card which introduced the concept of the two being brothers created to explore the new universe by an extradimensional entity, here named the "[[Allspark]]."''

''This was subsequently expanded on and combined with aspects of the various Marvel Comics stories in [[Transformers: The Ultimate Guide]], published by Dorling Kindersley and written by [[Simon Furman]], who had written all three prior tellings in the first place. Here, the entity Fleer had called the "Allspark" was redubbed "[[The One]]," and the modern iteration of the myth detailed above was firmly established, and went on to form the backbone of subsequent fiction such as ''[[Universe (2003 franchise)|Universe]]'' and [[Fun Publications]]' ''[[Cybertron (franchise)|Cybertron]]'' comics.''

==Generation 1==
===Marvel US continuity===
[[Image:Acolyte of unicron.jpg|left|100px|thumb|A Unicron cultist with mask. Or a cosplayer. Same thing.]]
Eventually, millions of years later, circa the Earth year 1990, a group of Transformers discovered the sleeping form of Primus at Cybertron's core. When a battle erupted, a stray laser blast struck Primus, briefly jolting the god awake and causing him to emit a multiverse-shaking "Primal Scream" that woke Unicron and alerted him to Primus' location. Primus himself immediately slipped back into his sleep, but it was too late.  {{storylink|Primal Scream|Primal Scream}}

Unicron re-created and dispatched a group of [[Hook, Line, and Sinker|heralds]] to retrieve a [[Galvatron II|Galvatron]] {{storylink|All Fall Down (issue)|All Fall Down}} who was plucked from an [[Rhythms of Darkness!|alternate future]] in which Unicron had succeeded in consuming Cybertron.   He sent all four of them to attack Cybertron and pave the way for his coming.   {{storylink|The Gathering Storm|The Gathering Storm}} 

So close to Cybertron he could ''taste it'', Unicron decided to forego consumption of the planet [[Jhi]] and hasten on his way to the ultimate confrontation.   His herald Galvatron, however, was not content to serve under Unicron, and instead captured Autobot leader [[Emirate Xaaron]], forcing him to fully awaken Primus.  Suspecting treachery on Galvatron's part, Unicron sent Hook, Line and Sinker to retrieve him from the screening subterranean tunnels of Cybertron, but Galvatron destroyed them, and Primus was woken from his slumber.  Unicron's arch-foe possessed Xaaron's body and summoned Transformers from all across the universe back to Cybertron.  {{storylink|Out of Time!|Out of Time!}} 

[[Image:Edgeofextinction-someonefight.jpg|right|150px|thumb|''He's got the whooooole world, in his feet...'']]
Unicron shut down his higher mental functions and drifted for the remainder of the journey to hide himself from detection by Primus.  At this point, a mental command that Unicron had placed in some of Primus's creations was activated, resulting in the formation of a cult of Unicron-worshippers, who gathered to destroy the leader of the united Autobots and Decepticons. 
These [[Unicron cultist|Unicron cultists]] were drawn out when [[Optimus Prime (G1)|Optimus Prime]] was named commander of Primus's army.  They tried to assassinate the [[Prime (rank)|Autobot leader]]; they failed, but distracted the Cybertronians long enough for Unicron to arrive.  {{storylink|The Void! (US)|The Void!}}

Transforming back to robot mode upon arrival, he was somewhat disappointed to find that the gathered Transformers were simply so terrified of him that there was no resistance to his attack. Unicron destroyed Xaaron's body, robbing Primus of his avatar, but was then attacked by his former servant, Galvatron, whose first strike snapped the Transformers out of their collective stupor and began a counter-attack against the Chaos-Bringer. Briefly fazed by the illusion-casting powers of the [[human]] [[Neo-Knights|Neo-Knight]] [[Rapture]], Unicron's systems were attacked by the electrical powers of [[Circuit Breaker]]. Enraged that he had been made to feel pain, Unicron dispensed with his hands-on approach and transformed into planet mode to consume Cybertron, at which point Optimus Prime flew into Unicron's maw and opened the [[Matrix of Leadership|Creation Matrix]], destroying the dark god.  {{storylink|On the Edge of Extinction!|On the Edge of Extinction!}}

His body destroyed in this timeline, Unicron's essence moved to another plane of reality, and made continued attempts on Primus and Cybertrons across many other realities.

====Earthforce====
''Due to unknown circumstances, Unicron was delayed in his advance towards Cybertron after the [[Primal Scream]] and [[Grimlock (G1)|Grimlock]] was able to use [[Nucleon]] to awaken the [[Underbase]]-offlined Autobots long before he arrived. {{storylink|Two Steps Back!}} While Grimlock formed [[Earthforce]], Optimus Prime continued to prepare the main force for Unicron's imminent arrival.'' {{storylink|Break-Away!}} 

''However, with an attempted Decepticon alliance ruined beyond all recovery and the Matrix still lost, Optimus had to turn to the original site of the Underbase—as the Underbase was linked to the centre of Cybertron, the Autobots could tap into that centre (and thus Primus himself) as a substitute Matrix. The Autobots succeeded in finding this site; it can be safely assumed that when Unicron finally got around to arriving, they were able to ''shoot him with the core of the planet''. See what happens when you put off doing something?'' {{storylink|The Magnificent Six!}}

[[Image:TFTM_Unicron_Lithone.jpg|right|200px|thumb|I see you down there!]]

Unicron's next known attempt on Cybertron (chronologically, the first documented) was his most famous, occurring in the Earth year 2005. While heading towards the planet, he consumed the small world of [[Lithone (planet)|Lithone]], making it perfectly clear how great of a threat he was to the entire universe. Along the way, he hacked into the security cameras of the [[Autobot City]] infirmary and witnessed [[Optimus Prime (G1)|Optimus Prime]] handing the [[Matrix of Leadership]] to [[Ultra Magnus (G1)|Ultra Magnus]] just before dying, which angered him tremendously. He then came upon the bodies of several wounded and dying Decepticons, who had been dumped into space following a [[Battle of Autobot City|recent battle]] on Earth. He extended a proposition to the Decepticons' leader, [[Megatron (G1)|Megatron]], offering to rebuild his body and those of his troops in exchange for their destruction of the Autobot Matrix of Leadership. Tortured into accepting, Megatron was transformed into [[Galvatron (G1)|Galvatron]], and his followers became [[Cyclonus (G1)|Cyclonus]], [[Scourge (G1)|Scourge]], and the [[Sweeps]].

[[Image:TFTM_Unicron_smashes_cybertron.jpg|thumb|left|200px|Unicron Smash!]]

While Galvatron set about reclaiming leadership of the Decepticons, Unicron arrived at Cybertron, and proceeded to consume the planet's two moons. Outraged that Unicron would do this to a planet that he viewed as his, Galvatron found himself the victim of mental torture by his creator, and ordered to Earth to complete the task given him. The ensuing chase finally climaxed in a showdown on the [[Junkion (planet)|Planet of Junk]], where Galvatron seized the Matrix and returned to Unicron, only to reveal that he intended to use the talisman to make Unicron his slave. Amused by his pawn's arrogance, Unicron transformed into his [[Scale|gigantic]] robot mode and ate Galvatron. Unicron then tore into Cybertron, as [[Shockwave (G1)|Shockwave]] and the rest of the Decepticons on the planet fought back, to little effect. Unicron swallowed many spaceships, and one, which contained the young Autobot [[Hot Rod (G1)|Hot Rod]] and his comrades, crashed through Unicron's eye. Hot Rod and Galvatron battled deep inside Unicron, and ultimately, Hot Rod was able to retake the Matrix from the Decepticon. Transformed by its power into [[Hot Rod (G1)|Rodimus Prime]], he defeated Galvatron and opened the Matrix inside Unicron, destroying his body from within. Unicron's head survived the explosion, however, drifting through space. {{Storylink|The Transformers: The Movie}}

{{note|This attack was performed by Unicron in several different universes. While the events of the attack itself were largely identical in each timeline, the consequences varied greatly from universe to universe. These timelines are noted individually below.}}

====Generation 1 cartoon====
:''Voice actor:'' [[Roger C. Carmel]] (English), [[Toshio Ishii]] (Japanese)

Unicron is an evil planet-gobbling world who reformed Megatron into Galvatron to lead the Decepticons into a new era.  {{storylink|Secret Files of Teletraan II|Secret Files of Teletraan II}}

[[Image:Unicron head orbit.jpg|180px|thumb|Incoming message from the [[Grand Mal|Big, Giant Head]]!]]

In the wake of the 2005 attack, Unicron's head was caught in Cybertron's gravity and became a new moon for the planet, a grisly testament to the satellites he had destroyed. Seeking to locate Galvatron, who had been hurled into space at the conclusion of his battle with Rodimus Prime, Cyclonus and Scourge visited Unicron's head and accessed the remaining databanks there, replaying footage of the final battle that allowed them to extrapolate Galvatron's trajectory and current location.  {{storylink|Five Faces of Darkness, Part 1|Five Faces of Darkness, Part 1}}

In the year 2006, the ghost of the deceased Decepticon [[Starscream (G1)|Starscream]] reactivated Unicron's head, in order to make a bargain with the Chaos-Bringer—in exchange for Unicron restoring his body, Starscream would recreate Unicron's. Stealing new optic circuits and a transformation cog for Unicron from [[Metroplex (G1)|Metroplex]] and [[Trypticon (G1)|Trypticon]], Starscream was then directed to connect Unicron's head to Cybertron, so that the planet could become his new body. Starscream initially attempted to do this by using Trypticon's body, but Trypticon was deactivated by the Decepticons. Unicron restored Starscream's body so that he could finish the task, but Starscream (somewhat predictably, being Starscream) double-crossed the dark god and refused to complete the necessary connections. Just then, explosives set by the Autobots were detonated, hurling Unicron's head off the planet, beyond its gravity, and out into space.  {{storylink|Ghost in the Machine|Ghost in the Machine}}

Later, seeking a supply of the dangerous particles known as [[Anti-electron|anti-electrons]], Galvatron and the Decepticons traveled to Unicron's head, only to come under attack from the defenses of the barely-aware giant. Also present was the [[Dinobot (G1)|Dinobot]], [[Grimlock (G1)|Grimlock]], who used components from Unicron's head to create the [[Technobot|Technobots]] to fight Galvatron's forces. The Technobot [[Strafe (G1)|Strafe]] disconnected enough of Unicron's internal mechanisms to deactivate his systems.  {{storylink|Grimlock's New Brain|Grimlock's New Brain}}

{{note|The episode "[[Call of the Primitives]]" eventually revealed that, in this timeline, Unicron was created near the beginning of time by an ancient genius named [[Primacron]], to destroy the universe so he could remake it in his own image—here, he was simply a gigantic robot, rather than any kind of godlike being. This, of course, is because the cartoons were written long before the Marvel Comic storyline that created the Primus/Unicron myth, and ''much'' longer before the retcon that applied the story to all Transformer continuities. Consequently, the animated universe is easily the one piece of Transformer fiction that is least compatible with this retcon, but there has as yet been no attempt in official fiction to re-write Unicron's animated origin to tie in with it.}}

=====Kiss Players/Teletraan Go! Go!=====
[[Image:TGGUni1.jpg|left|180px|thumb|Bwah ha ha ha ha ha ha ha ha]]
Following his destruction in 2005, Unicron's [[Angolmois|lifeforce]] was scattered across time and space, fragmented and parasitized into Autobot and [[Maximal]] leaders throughout history. In 2007, three of his servants, the [[Sparkbot|Sparkbots]], sought to recreate their master, and tricked the human singing group, the [[Kiss Players (singing group)|Kiss Players]]—[[Marissa Faireborn]], [[Atari Hitotonari]] and [[Shaoshao Li]]—into helping them in their task by telling them that they were gathering the fragments of the so-called "Allspark."

[[Image:TGGUni2.jpg|right|180px|thumb|Oh god ha ha ha ha ha ha ha ha]]
[[Primus]] was forced to take action to stop their mission, appearing as a giant golden hand to steal away the energy fragments before the Sparkbots could collect them, but eventually, the evil trio collected enough to accomplish their dire task. Fleeing back in time to [[Earth]]'s prehistoric past, they unleashed the energy and Unicron began to form around them. Following the Sparkbots back to the past, Primus unleashed the full firepower of his mobile battle platform's cannon, sealing Unicron's energy and the Sparkbots deep within the planet. He then created the mighty [[Fortress Maximus (RID)|Fortress Maximus]] to serve as a guardian and ensure that the evil being was never again reborn.

Fortress Maximus left Earth in 2007, a event that allowed humans to discover the lifeforce in the far future.

====Marvel UK continuity====
[[Image:MarvelUK-253.jpg|left|150px|thumb|Wow, he sure fears the [[Matrix of Leadership|Matrix]].]]
''In the timeline of [[Earth-120185]], Unicron's famous attack on Cybertron occurred in 2006, rather than 2005. Galvatron briefly escaped Unicron by time-jumping to 1986 and constructed a solar cannon that was powerful enough to destroy the monster's physical form, but Unicron took control of [[Hot Rod (G1)|Hot Rod]], [[Kup (G1)|Kup]], and [[Blurr (G1)|Blurr]] and had them go back in time to ruin the plan.''  {{storylink|Target: 2006|Target: 2006}} 

''After that, events carried on exactly the same and the Matrix blew him up. Rather than become Cybertron's moon, however, Unicron's head floated off through space and crash-landed on the planet [[Junkion (planet)|Junkion]], where he used mind control to force the native [[Junkion|Junkions]] to build him a new body out of the planet. At the beginning of 2008, he pulled [[Cyclonus (G1)|Cyclonus]], [[Scourge (G1)|Scourge]] and [[Death's Head]] into his thrall and used them to re-ignite the stalemated Cybertronian war in order to keep the Autobots distracted from his activities. Ultimately, however, he was defeated by [[Death's Head]] and the Autobots. His head was destroyed, and his mind was sealed within the [[Matrix of Leadership|Matrix]].''  {{storylink|The Legacy of Unicron!|The Legacy of Unicron!}}

''On New Year's Day 2009, Unicron reached out from within the Matrix and took control of [[Hot Rod (G1)|Rodimus Prime]]'s body,  {{storylink|Edge of Impact|Edge of Impact}} only to be stopped when Kup ripped the talisman out of his chest. Unfortunately, this meant they lost their chance to purify the Matrix and that Unicron would be ready for them next time.  {{storylink|White Fire|White Fire}} In 2010, he repeated the trick and succeeded in transforming Rodimus's body into a copy of his own before being forced back. In the far future of 2356, Unicron's essence still resides within the Matrix, steadily withering the struggling body of Rodimus.''  {{storylink|Aspects of Evil!|Aspects of Evil!}}

{{note|The concept that Transformer weaponry could destroy Unicron was never brought up again after "Target: 2006", and doesn't quite fit with the idea of Unicron as primordial demi-god. This was, however, written before Furman came up with that origin for the guy.}}

===Dreamwave Generation 1 comics===
Unicron hovered in the background in this universe, an unseen and unknown presence. His servant, [[The Fallen]], tried to bring about his second coming by breaking the [[Seal of Primus]], but failed.  {{storylink|The War Within: The Dark Ages|The War Within: The Dark Ages}} Unicron sent a wave of drones and heralds into the universe, with the Alpha Drone Scourge arriving on Cybertron 3000 years ago; he ended the [[Great Shutdown]] when he reactivated Shockwave for research purposes.  {{storylink|Generation One issue 0|Generation One issue 0}} Shockwave happily shot him and experimented on him, and would later cause an energy spike that woke Unicron up (it's unknown if he meant to, but presumably he didn't).  {{storylink|Revelation (War and Peace)|Revelation}}

Unicron went on a course towards Earth, porking his way through the planet [[Lithone (planet)|Lithone]] and creating a new servant Cyclonus in the process. 

{{note|He was going to be part of a big plotline in 2005, starting from #13  {{storylink|Unreleased Dreamwave issues|Unreleased Dreamwave issues}}, but even Unicron's might was helpless against Pat Lee's business skills.

===''G.I. Joe vs. the Transformers''===
Here, Unicron enslaved the population of the worlds he ate to maintain his inner works; one race included the [[Battle Beasts]]. He is known about in Transformer legend, and is said to have been banished from his homeworld.

[[Image:Unicron's DDP Brain.jpg|right|200px|thumb|Who needs all those TV monitors, anyway?]]
Thousands of years ago, when humanity was at a primitive stage, Unicron turned up to devour the Earth. The ancestors of [[Cobra-La]], however, had developed a metal-eating spore that could potentially kill Unicron. They came to an agreement—they would go into exile, while Unicron would merely eat human civilisation once it had developed to a useful point. Eventually they did, and Unicron began broadcasting announcements of "I Return" as he headed towards Earth.  {{storylink|Black Horizon, Part 1 of 2|Black Horizon Part 1}}

Unicron reached Earth and transformed so as to consume civilisation in robot form. [[Japan]] was devastated and humanity collectively wet itself. But the world was saved by [[Cosmos (G1)|Cosmos]] and [[Flint (G.I. Joe)|Flint]], who flew into the Chaos-Bringer and doused his organic looking brain with Cobra-La's metal-eating spores. Unicron was killed, the world was saved, and [[G.I. Joe]] went on to explore the dead monster's innards.  {{storylink|Black Horizon, Part 2 of 2|Black Horizon Part 2}}

{{note|With no mention of the Primus/Unicron mythology (instead mentioning a banishment), the willingness to only eat parts of worlds and leave their populations alive to serve him, and his death-by-fungus, Unicron in Devil's Due does differ ever-so-slightly from his depiction by other companies. This story was published '''after''' the retcon saying the Primus/Unicron myth applies to all continuities, yet seems to be ignoring it; this could make it the first post-retcon Transformers media to retcon away the retcon.}}

[[Image:Matrix of conquest.jpg|right|150px|thumb|The Evil Galactic Starfish of Conquest served as a container for Unicron’s power.]]
In yet ''another'' timeline that followed his destruction in 2005, Unicron's essence was again sent spiraling through time and space, to crash on prehistoric Earth, prior to the conflict known as the [[Beast Wars]] which would occur on the planet. It is unclear if this was a deliberate attempt by Unicron to preserve his power or not, but this "dark essence" seemed to lack any real sentience, suggesting that it was merely Unicron's "power," while his spark remained in his intact head in the future. 

The dark essence was discovered by a [[Predacon (BW)|Predacon]] known as the Hunter, who recognized the dark god's power, and fashioned from the essence the [[Matrix of Conquest]], a twisted version of the Autobot Matrix of Leadership which he used to conquer and rule over an apocalyptic 32nd Century future, under the name "[[Shokaract]]". Resistance against Shokaract resulted in an attempt by his opponents to travel back and time and destroy the dark essence on prehistoric Earth, thereby erasing Shokaract from history, but the villain travelled back in time to stop this effort. A massive battle between him and Transformers from throughout the multiverse ensued, but eventually, thanks to the efforts of the [[Covenant]], history was altered so that Unicron's essence never arrived on prehistoric Earth, erasing this timeline—and Shokaract—from existence.  {{storylink|Terminus|Terminus}}

===IDW ''Beast Wars'' comics===
Sometime after a series of events similar to those of [[Lio Convoy]] and [[Big Convoy]]'s [[Beast Wars II (franchise)|experiences]] [[Beast Wars Neo (franchise)|on]] [[Gaea]] in another universe, Unicron's heralds, the [[Blendtrons]], were instructed by the Chaos Bringer's essence to gather the [[Angolmois]] capsules scattered across the galaxy, which contained Unicron's energy.  The taint of [[Angolmois]] would cause unrest and violence across Cybertron as the planet tore itself apart in renewed savage mindless conflict.  At the same time, Unicron's chosen yet unwitting vessel, Shokaract, was fed Angolmois by the Blendtrons, having been convinced that it would grant him the power to be reborn as a god. In one potential timeline, this did indeed happen as Unicron was reborn from Shokaract's corrupted form, and the Chaos Bringer proceeded to consume Cybertron itself.  

However, this was averted before it came to pass - thanks to the actions of the in-temporal-limbo [[Magmatron]], who alerted [[Ravage (G1)|Ravage]] and by extension Lio Convoy to Unicron's plan and enlightened Shokaract when the tyrant was temporarily shunted into Magmatron's personal purgatory.  Realizing what his ascension actually entailed, Shokaract tore a Dead Matrix of some sort from his chest, sacrificing himself and ending Unicron's latest plan at re-ascension.

During Megatron's rule of Cybertron, [[Rattrap]] once compared the Predacon's [[Grand Mal|big floating head]] as a "monument to Unicron", implying that the Chaos Bringer's head orbited Cybertron after his defeat. However, it was never seen from the surface, perhaps implying that it had left Cybertron's orbit.  {{storylink|Prometheus Unbound|Prometheus Unbound}}

===''Beast Wars II'' cartoon===
Human beings at some point in the future were eventually able to discover Unicron's lifeforce and attempted to harness it for their own means. This resulted in the devastation of the planet Earth, reducing it to a ruin, but the fame of this "mysterious energy" that had been called "[[Angolmois]]" was far-reaching, and eventually, the Predacon leader [[Galvatron (BWII)|Galvatron]] attempted to harvest it for himself.  {{storylink|The New Forces Arrive!|The New Forces Arrive!}} Using his artificial planet, [[Nemesis (BWII)|Nemesis]], he sucked all the Angolmois energy out of the planet and into the craft. However, after the interference of [[Lio Convoy]] and [[Lio Junior]], all the Angolmois energy was sealed into capsules and ejected from Nemesis as it self-destructed.  {{storylink|Farewell, Lio Convoy!|Farewell, Lio Convoy!}}

Teams of Maximals and Predacons, led by [[Big Convoy]] and [[Magmatron]] respectively, then raced to collect the Angolmois capsules, as their energy effects were wreaking havoc on planets all over the galaxy.  {{storylink|Big Convoy, Move Out|Big Convoy, Move Out}} They eventually collected all the capsules only to find themselves attacked by the mysterious and freakish [[Blendtron|Blendtrons]]. The Blendtrons, in truth servants of Unicron seeking to engineer his rebirth, proved nearly invincible, and stole the capsules from each team.  {{storylink|Mysterious Beast Warriors!?|Mysterious Beast Warriors!?}} They released the Angolmois energy and allowed it to possess Galvatron's dead body, restoring Unicron to life in a new form. Unicron proceeded to absorb the last remaining ounce of stray Angolmois energy—the Blendtrons themselves—and left to settle his score with Cybertron. The [[Maximal Elder]], [[Great Convoy]], attempted to hold Unicron off with the entire Maximal armada, but Unicron's fiery serpent mode proved too much and he effortlessly destroyed the armada and Great Convoy along with it. Unicron then possessed [[Vector Sigma]], the mother computer of [[Cybertron (planet)|Cybertron]], effectively possessing the planet, and morphed Cybertron into his new body.  {{storylink|Unicron's Ambition|Unicron's Ambition}}

Unicron then briefly exited Vector Sigma to deal with the last remaining Cybertronian resistance.  {{storylink|The Final Battle (BWN)|The Final Battle (BWN)}} Big Convoy, his Maximal new recruits, Lio Convoy and Magmatron all fought side-by-side against Unicron, but all they managed to do was stall him.

Big Convoy shot Unicron with the weapon, the powerful blast seemingly destroying the Chaos Bringer. Unicron's spirit was then evicted from Vector Sigma, returning Cybertron to normal.  {{storylink|Graduation Ceremony!!|Graduation Ceremony!!}}

On the planet Gaea, a group of Predacons somehow came into possession of a mysterious spheroid object known as the '''Black Ball'''.  The strange artifact was of some importance to the Predacons; it may in fact have told Magmatron that he could rule the galaxy once he had the seven [[Angolmois]] capsules.

When Big Convoy came to rescue [[Longrack (BWN)|five]] [[Break|Maximal]] [[Cohrada|rookies]] [[Stampy|who]] [[Heinrad|were trapped]] in the Predacon base on Gaea, the Maximals found the Black Ball and retrieved it.  {{storylink|The Five Rookies|The Five Rookies}}

After the Maximal returned to the ''[[Gung Ho]]'', they attempted to analyze the Black Ball. However, the Black Ball activated the ship's warp engine. During the warp, the Black Ball began to speak, telling the Maximals about the Angolmois capsules, which originated from the final conflict between [[Lio Convoy]] and [[Galvatron (BWII)|Galvatron]] on the [[Nemesis (BWII)|Nemesis]]. It also told them that there were seven Angolmois energy capsules scattered across the galaxy in total. The Maximals were warned that they must retrieve all the capsules to prevent them from falling into the wrong hands, or the galaxy would be in extreme danger. The ''Gung Ho'' subsequently arrived at the planet [[Sandron (planet)|Sandron]], where one of the capsules was located.  {{storylink|There are Seven Capsules|There are Seven Capsules}}

The Black Ball guided Big Convoy's team to various other places where capsules were located.

When Magmatron, who was in the healing room due to wounds caused by Big Convoy, learned that he [[Guiledart|lost]] [[Saberback|his]] [[Sling|main]] [[Dead End (BWN)|troops]] in the battle on [[Jörmungandr]], the Black Ball suddenly showed up from nowhere. The Black Ball told Magmatron that it could see he was short-handed. The Black Ball offered Magmatron some "helpers" — the [[Blendtron|Blendtrons]], who emerged from within the Black Ball.  {{storylink|A Battle Fought Alone|A Battle Fought Alone}} 

The Black Ball told both Big Convoy and Magmatron of the planet where the last capsule was located. Magmatron faced off with Big Convoy there, and ordered the Blendtrons to attack the Maximals.  One of the Blendtrons, however, chose to attack Magmatron instead. The action of the Blendtrons baffled both Big Convoy and Magmatron alike.  The Black Ball then arrived on the planet's surface.  {{storylink|Double Cross|Double Cross}}

It was revealed that the Black Ball was actually Unicron himself, or more specifically, his essence, while the Angolmois energy was his life force. Unicron absorbed the six capsules and reformed his head out of the Black Ball. He then revealed that the last capsule was actually Big Convoy and Magmatron, who were evolved by the power of the Angolmois capsule on their home planet.  {{storylink|Double Cross|Double Cross}}

Big Convoy teamed up with Magmatron to fight against Unicron, but failed. Big Convoy was saved by [[Heinrad]], while Magmatron was chewed up and spat out by Unicron. After dealing with the Transformers, Unicron headed to the planet Cybertron. He latched onto the planet like a parasite and turned it into his new body.  {{storylink|Double Cross|Double Cross}}

Unicron desired to consume Big Convoy, the last half of the capsule, in order to make his right eye fully functional once more. His physical body was destroyed by Big Convoy after a harsh battle with Big Convoy's crew. However, Unicron's essence emerged from his physical remains and plastered itself onto Big Convoy's body, trying to possess him. Big Convoy removed the [[Energon Matrix|Matrix]] from his chest and unleashed its power, sacrificing himself and successfully destroying Unicron once and for all.  {{storylink|Return to Zero|Return to Zero}}

Just as the Transformers were beginning to settle into post-[[Vehicon (BM)|Vehicon]] life on the newly-technorganic Cybertron, Unicron struck once more. His body ruined and trapped between dimensions, he sought to revitalize himself by abducting Transformers from across the multiverse and pitting them against each other within his own body, absorbing their [[energon radiation]] and eventually consuming their sparks. He chose to kidnap several Autobots and Maximals from the technorganic Cybertron, but that was also the staging ground from which Primus chose to launch a counterattack. Primus gathered an army from many different universes and put the resurrected [[Optimus Primal]] at its head.  {{storylink|Abduction|Abduction}}  

These "[[Child of Primus|Children of Primus]]" raided Unicron to free his captives from their prison cities, battling Unicron's own legion of "[[Minion of Unicron|Minions]]" all the while. [[Universe war|These conflicts]] escalated for months or perhaps longer, their intensity rivaling the [[Cybertronian Civil Wars|Great Wars]].<ref>Optimus Primal's bio in the [[Revelations Part 3|Transformers Collectors' Club comic #9]]</ref> This all came to an abrupt end during the final battle, when Unicron simply vanished due somehow to the [[Unicron Singularity]].  {{storylink|Revelations Part 2|Revelations Part 2}}

==Unicron Trilogy==
{{note|The [[Unicron Trilogy]], the series of Transformers franchises that includes ''[[Armada (franchise)|Armada]]'', ''[[Energon (franchise)|Energon]]'', and ''[[Cybertron (franchise)|Cybertron]]'', was so named by Hasbro designer [[Aaron Archer]] because of Unicron's importance in each story.}}
===Dreamwave comics continuity===
====''Armada''====
[[Image:Unicronarmada.jpg|left|150px|thumb|"For a time, I considered sparing your giant invisible sandwich."]]
After successfully devouring the Cybertron of a previously unseen dimension, Unicron sent a group of heralds—incarnations of [[Bludgeon (G1)|Bludgeon]], [[Dirge (G1)|Dirge]], [[Galvatron (G1)|Galvatron]], [[Scourge (G1)|Scourge]], and [[Thunderwing (G1)|Thunderwing]]—to prepare the next universe for his coming. As forewarning, he also sent the near-dead body of the [[Optimus Prime (Worlds Collide)|Optimus Prime]] of that other dimension, which was discovered by the Autobots of the next universe.  {{storylink|Worlds Collide, Part 1 of 4|Worlds Collide, Part 1 of 4}}

Unicron was ultimately defeated by [[Optimus Prime (Armada)|Jet Optimus]], the combined form of this universe's Optimus Prime and [[Jetfire (Armada)|Jetfire]], who were infused with extra [[Mini-Con]] power. However, during his attack on Cybertron, he had managed to kidnap [[Airazor (Armada)|Airazor]], [[Cheetor (Armada)|Cheetor]], [[Rhinox (Armada)|Rhinox]] and [[Terrorsaur (Armada)|Terrorsaur]], and would see them forged into new heralds in the interim. This universe's [[Megatron (Armada)|Megatron]], having made a bid for Unicron's power, was standing on the surface of the planet-eater when he was destroyed, and his body was also lost, his spark trapped within Unicron's remains.  {{storylink|The End|The End}}

====''Energon''====
{{cleanup|February 2009|Unicron appeared a fair bit more than this}}

His broken body left floating in space after his defeat, Unicron employed the go-between [[Alpha Quintesson]] to see to his continued survival. Alpha Quintesson gathered together a group of Decepticon dissidents and transformed them into "[[Terrorcon (Energon)|Terrorcons]]", although he himself was not overly thrilled with his position of enforced servitude.  {{storylink|This Evil Reborn|This Evil Reborn}} At the same time, Megatron had been using Unicron's powers and internal mechanisms to fashion a new body for himself, unbeknownst to Unicron himself.  {{storylink|Multiplicity|Multiplicity}}

{{note|Due to the sudden demise of [[Dreamwave Productions|Dreamwave]], the conclusion of this story remains unknown. Presumably, since you are alive and reading this, Unicron did not go on to consume the Omniverse.  Or did he?  For all we know he may be heading to our universe as we speak.}}

===Cartoon continuity===
Unicron was evidently very active in this dimension at various points in time, although the precisely chronological placement of this activities are unclear.

At some undetermined point in the past of this universe, Unicron was approached by the survivors of [[Planet X (Cybertron)|Planet X]], a world that had been destroyed in a war with the inhabitants of the Giant Planet, [[Gigantion]]. In return for the chance to gain revenge on Gigantion, the survivors swore loyalty to Unicron, and "Planet X" became something of a code-phrase that identified those in the service of the planet-eater.

{{note|Liner notes included with the DVD release of ''Galaxy Force'' in [[Japan]] claim that Planet X is actually the body of Unicron from another parallel dimension. This would not appear to be compatible with the Western storyline, nor, indeed, with the date later given to the planet's destruction on the [[TakaraTomy]] "[http://www.takaratomy.co.jp/products/TF/bible/index.html World of the Transformers]" website.}}
Additionally, Cybertronian legend refers to an attack by Unicron on the planet that was ultimately thwarted by the mighty Autobot warrior, [[Omega Supreme (Energon)|Omega Supreme]].

====''Armada'' cartoon====
:''Voice actor:'' [[Mark Acheson]] (English), [[Katsumi Chō]] (Japanese)

Unicron's first attack on Cybertron in the present day was an indirect one, over a million years in the making, begun when he opted to disguise his dormant body as Cybertron's moon. From this secret vantage point, he implanted his own cells within the planet, where they germinated and grew into the small race of robots known as the [[Mini-Cons]]. Unicron hoped to use the Mini-Cons to increase the ferocity of the Autobot/Decepticon war, and feed off of the energies released in the conflict, but an encounter with a group of [[Rad White| time-displaced]] [[Carlos Lopez| human]] [[Alexis| children]] planted the seed of sentience and free will within the Mini-Cons, who ultimately rebelled against their creator and fled Cybertron, crash-landing on the planet Earth.  {{storylink|Origin|Origin}}

When the Mini-Cons were reawakened a million years later in 2010, they were detected by the Autobots and Decepticons, who followed their signal to Earth.  {{storylink|First Encounter|First Encounter}} Unicron also picked up the signal, and dispatched his minion [[Sideways (RID)|Sideways]], an inhabitant of Planet X who would occasionally serve as an avatar for Unicron's spark, to carry on his work.  {{storylink|Gale|Gale}} Sideways escalated the conflict by manipulating control of the three Mini-Con weapons, the [[Star Saber (Armada)|Star Saber]], the [[Skyboom (Armada)|Skyboom]] shield and the [[Requiem Blaster]], but eventually arranged for all three to be returned to Cybertron, where he stole them and used them to reawaken Unicron.

[[Image:ArmadaUnicron02.jpg|right|200px|thumb|The Power Cosmic gives you wrinkles.]]
Shedding his moon disguise and transforming to robot mode, Unicron turned on Cybertron, only to be met with resistance in the form of the united armada of Autobots and Decepticons  {{storylink|Alliance (episode)|Alliance}}, and his own Mini-Cons, who had linked together and formed a giant duplicate of his body.  {{storylink|Union|Union}} Now at full power, however, it was child's play for Unicron to exert control over his creations, and bring the Mini-Cons under his thumb once more. Again, it was thanks to the Autobots' human allies—the same children who had been sent back in time and given the Mini-Cons free will in the first place—that the Mini-Cons struggled free of Unicron's control, including the three Mini-Con weapons, who broke free and left Unicron's body deactivated. Believing the threat over, [[Megatron (Armada)|Galvatron]] then challenged Optimus Prime to their final battle, only for the hatred and ferocity of their fight to awake Unicron once more. To end the circle of hate that gave Unicron life, Galvatron allowed himself to be consumed by the monster, and in a brilliant flash of light, Unicron apparently ceased to exist.  {{storylink|Mortal Combat|Mortal Combat}}

====''Energon'' cartoon====

{{cleanup|February 2009|Needs storylinks.}} [[Image:Energon Unicron.jpg|left|180px|thumb|Unicron sported awesome colors during ''Energon''.]]
In truth, however, Unicron had survived, and for the next ten years, continued to consume planets in other regions of space. One such planet was the world known as [[Planet Q]], whose inhabitants fought back by detonating the planet's core in Unicron's face. Badly damaged by the explosion, Unicron fell into a state of dormancy, but the life essence of the planet's ruler—the being who would come to be known as [[Alpha Quintesson|Alpha Q]]—continued to exist within him, and began a not-entirely-sane plan to use Unicron's powers to recreate everything the Chaos-Bringer had ever destroyed. Recreating the armies of Planet Q as "Terrorcons," Alpha Q had them attack Autobot facilities on Earth and throughout the [[solar system]] to gather the [[Energon (Energon)|Energon]] that would be necessary for his plan to work. 

Unbeknownst to Alpha Q, Megatron's corpse and spark remained within Unicron, and he slowly siphoned off some of the gathered Energon, allowing him to be reborn in his own new body. To escape Megatron's fury, Alpha Q 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.

[[Image:Unicron eats blizzard.jpg|right|180px|thumb|Unicron should stop eating so many Blizzards.]]
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. The Autobots made a valiant but futile attempt to stop him, but Unicron decimated them. Just as things seemed hopeless, a surge of power came that allowed Optimus-Supreme to grow to Unicron's size and powered up the other Autobots, and after a long and hard battle Optimus destroyed Unicron's body.

None of the Transformers were aware, however, that Unicron lived on in two forms: his miniscule Spark, floating in space, and his consciousness, which lay buried in Megatron's mind. With quiet, subconscious nudging, 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 made the decision to plunge himself into the infant sun to rid himself of Unicron's possession. The super energon mass, having now received Unicron's spark, ignited into a powerful red sun which gave new life to Alpha Q's worlds.  {{storylink|The Sun|The Sun}}

Primus's plan to trap Unicron in the heart of a new sun failed when the star collapsed into a massive [[Unicron Singularity|black hole]] (sometimes known as the "Unicron Singularity") that threatened the entire multiverse.  {{storylink|Fallen (episode)|Fallen}}

====''Cybertron'' comic====
[[Image:Unicroncybertron.jpg|right|150px|thumb|The Planet-Eater's back, and you're gonna be in trouble.]]
Unicron's heralds [[Ramjet (Universe)|Ramjet]] and [[Nemesis Prime (Universe 2003)|Nemesis Prime]] arrived on Cybertron, intent on unleashing the [[Dead Matrix]] on Primus's vulnerable essence—as the Matrix was the antithesis of Unicron, so too would the Dead Matrix ensure the destruction of Primus, thereby totally destabilizing the multiverse and reducing it to a sea of entropic chaos. For the first time, it would be possible for Unicron to strike at Primus in all realities simultaneously, ending their cosmic feud once and for all.

Ramjet and Nemesis Prime were ultimately stopped by Vector Prime and allies [[Sentinel Maximus]] and [[Omega Prime]], plucked from the midst of the ''Universe'' conflict by the multiverse-warping energies of the black hole. The Dead Matrix, however, taken by Unicron's servant [[Soundwave (Cybertron)|Soundwave]] and cast into the heart of the black hole, freeing Unicron's spark, which entered the planet [[Yst]] and immediately began to sow chaos and disorder. Re-energized by the hatred and violence than ran rampant on Yst, Unicron formed a new, diminutive body for himself, born into the universe when Yst exploded.

During the time that followed, from behind the scenes Unicron orchestrated a civil war between the Mini-Cons stationed on Cybertron's moons.  {{storylink|Revelations Part 4}} When Sentinel Maximus led a team of Autobots to stamp out the escalating conflict, Unicron's involvement was revealed, but before he could achieve victory, Primus was reawakened, and the Dark God fled as Cybertron transformed into its robot mode.  {{storylink|Revelations Part 6}}

===''Transformers'' (Armada) game===
:''Voice actor:'' [[Matthew King]] (English)

After the Autobots defeated the Decepticons on [[Earth]] and had secured the majority of the Mini-Cons there, Unicron made his appearance above Cybertron, intent on destroying the planet. Optimus Prime's team of Autobots and the Mini-Cons returned home via a warp gate to see the Chaos Bringer unleash a wave of destruction upon the great cities of their planet. The Mini-Cons joined together to form the [[Matrix Cannon]], the [[Vanguard Booster]] and the [[Nemesis Shield]] for the Autobots to use against Unicron. The Autobots flew into Unicron's maw and blasted their way into his energy core, damaging it enough to send Unicron spiralling out of control and destroying him.  {{storylink|Transformers (Melbourne House)|Transformers}}

==Movie (2007)==
===Titan Magazines===
While the Transformer race appears ignorant of Unicron, [[Starscream (Movie)|Starscream]] has knowledge of him and encountered him  {{storylink|Transformers Comic issue 12|#12's Star Screams}} in an event where Unicron attempted to devour Cybertron.  {{storylink|Transformers Comic issue 19|#19's Star Screams}} We don't know how Starscream witnessed this (did he hop dimensions?) but it has left him terrified.  {{storylink|Transformers Comic issue 17|#17's Star Screams}}

[[Stockade (Movie)|Stockade]] and his Decepticon chums attempted to rebirth Cybertron by sending out a summons that would attract any entity related to the lost [[All Spark]], and then drawing that entity into Cybertron once it arrived.

As that entity announced itself to be '''"Unicron the Anti-Life!"''', they felt like a right bunch of plonkers.  {{storylink|Return to Cybertron: Part 2|Return to Cybertron: Part 2}}

Unicron moved swiftly, transforming Cybertron into a scarier looking physical form and causing the planet's surface to becoming hostile to the Transformers on it. Stockade's attempts at communication were met with contempt and a strange attack. The new Unicron then warped into the Sol system, shot down an Autobot shuttle, and went "OM NOM NOM" at the sight of Earth.  {{storylink|Return to Cybertron: Part 3|Return to Cybertron: Part 3}}

The downed Autobots regrouped with Stockade's Decepticons and worked to take away the [[Nucleon]] that was powering Unicron's physical form. They succeeded in this by causing it to blow up and catch fire, which caused Unicron to draw on more Nucleon to recover, which fueled the fire and so on until the source ran out. Unicron disappeared, though whether he's dead or just gone is ambigious.  {{storylink|Return to Cybertron: Part 4|Return to Cybertron: Part 4}}

Either way, the changes Unicron had made to Cybertron remained. The teleportation equipment he'd created was used by the Autobots to finally end the war. {{storylink|Transformers Comic issue 25|Revolution Part Three}}

==Trivia==
[[Image:Model-TheEntity.jpg|right|100px|thumb|Flamboyantcron.]]
* Before the Transformers brand even existed, Takara designer [[Hiroyuki Hataike]] drew up a "Planet-Robot" toy for the [[Micro Change|Microchange]] line, a design that would eventually inspire Unicron.

* In early preproduction for ''The Transformers: The Movie'', Unicron was referred to as the '''Entity'''.

* A model sheet from later in the movie's preproduction revealed that, at one point, the ''planet'' Unicron would turn into the ''robot'' '''Ingestor'''. This idea was, obviously, dropped before the film's release.

* When Unicron exploded in the Marvel Comics continuity ("[[On the Edge of Extinction!]]"), the tear in existence his destruction caused resulted in creating the [[Classics (2006)|Classics]] universe.  This [[splinter timeline]] began overwriting the [[Tonka Go-Bots]] universe.  That's right.  Unicron killed the Go-Bots.  <ref>According to the Collectors' Club text story, [[Withered Hope]].</ref>

*[[Roberto Orci]] is interested in having Unicron in ''[[Transformers 3]]''.[http://www.tfw2005.com/transformers-news/transformers-movie-just-movie-31/ask-roberto-orci-roundup-january-14---mythology-money-shots-jolt-military-and-bringing-chaos-166603/]

* Unicron has the ability to create [[tainted world]]s, but none yet have been discovered.
