Our race was created for a higher purpose. What we do, we do to prepare for the true finality... the end of not merely our universe, but of all creation. The Unicron Phenomenon seeks to consume all that ever was and ever will be. We have faced it and bested it once, as have other Transformers from other universes. But it will return. It is beyond time, and will try again after consuming other realities. We must be ready. We must survive, and must always be there to stand against the nothingness Unicron seeks to bring about.
~ Megatron teaches Path Finder about the TransTech.
Unicron is the eternal arch-enemy of his twin brother Primus. Also known as the Lord of Chaos, the Chaos Bringer, and the Planet Eater, he is dedicated to consuming the Transformers multiverse. His massive form is powered by the consumption of planets, moons, stars, and even the very fabric of existence. Unicron will not be sated until his ultimate goal is attained: to bring an end to the annoying creation boasting independence around him, and find peace by becoming the living center of a 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. Integrated into his systems are incomprehensible quantum computers which calculate probabilities forward and backwards in time, in perpetuity, giving his processors an ever changing, evolving map of the multiverse. With these abilities at his disposal, Unicron has thus far devoured approximately 22.56% of known universes. Seen at a detached distance from the multiverse, this collective "Unicron Phenomenon" acts with the characteristics of a virus or plague seeping through reality and succeeding where it can, and retreating when it cannot. Various permutations of Unicron can spawn into existence outside the trappings of the larger entity, hailing from a more mundane origin but possessing the same consumptive traits. For much of multiversal history, the singularity Unicron threatened all of existence, but now, that is no longer the case, versions of Unicron being restricted to their own dimensions.

The only thing that he fears is Primus's essence, contained inside the Matrix of Leadership. To a being of chaos and uncreation, this font of life is a poison.

Frequently, Unicron will make deals with lesser beings, promising 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, Unicron's plans ultimately call for their consumption as well.

Unicron was established as a multiversal singularity, existing as one being across all of time and space, but in the event known as Shrouding (initiated by Nexus Prime that altered the fabric of the multiverse) his true form as a multiversal singularity was divided into infinite universes. Now each reality in the multiverse could have its own Unicron, or not, or its own origin of the Transformers without that decision affecting other franchises in the process.

The feats cited in this section are of the character before the event known as Shrouding, or Unicron as a multiversal singularity.

  • His presence exerts a powerful effect on all measurable quanta... in layman's terms it can distort reality, and even if one manifestation is defeated or destroyed in a universe, it remains in others, and one day will return to try again.
  • The linear time is not a concept that binds an entity of Unicron's level. It has all the time in all worlds, and if it does not, it can make the time... literally.
  • Exists across the multiverse, can pull heralds from across space and time.
  • Can torture Megatron/Galvatron from across star systems, possessing his Armada/Energon and Prime counterparts.
  • Unicron began to consume world after world, reabsorbing the energy that it had lost creating other tainted worlds. Tainted worlds differ in their nature from one part of the Multiverse to the next.
    • Some planets will undergo a technological reformatting, causing the planet and everything on it to turn into a drone searching for other planets to sate Unicron's hunger. There are realities where Lithone is reformatted into such a world, imbued with the savaged remnants of the intellect of its last survivor, Kranix, questing through the void in its ominous journey.
    • Other tainted worlds will rapidly mutate those on it into mindless beasts, which would be equivalent to your "seasonings" and has the added benefit of reducing the likelihood of effective resistance. A form of this was used on Yst to allow for Unicron's body to reform.
    • Some tainted worlds become ragged scars in the fabric of reality itself, causing quantum-foam-level instabilities and disrupting local space-time. Over time, they cause jagged wounds in the heart of a reality Unicron is not yet ready to obliterate. The Dark Nebula originally had such a world at its heart.
  • The maximum power of Unicron exceeds or equals the power of the True Star Saber (Prima's sword), which has the power to destroy or save the multiverse/megaverse of Transformers. The Star Saber, in conjunction with the Terminus Blade, was later used to strengthen the barriers between all universes to further separate them, which nullified the concept of multiversal singularities. In the past he was only defeated by the combined power of the Thirteen, the first transformers created by Primus: Prima, Liege Maximo, Megatronus (The Fallen), Vector Prime, Logos Prime, Nexus Prime, Onyx Prime, Solus Prime, Alchemist Prime, Epistemus, Solomus, Autonomous Maximus (The Last Autobot), Micronus Prime. The list of the Thirteen transformers can change in the Aligned continuity. Prima used his sword in the fight against the dark god.


  • Unicron has no weaknesses, though the power of the Autobot Creation Matrix (Matrix of Leadership) can temporaly disable him. He is deeply afraid of his brother Primus, despite the fact that it is almost certain he would be victorious in a head to head fight.
  • Virtually invulnerable in the physical sense, Subject can ignore most attacks with an obliviousness that transcends mere arrogance. However, it is concepts such as innocence and purity. The basic ideas of "goodness" are intrinsically incomprehensible by Subject, being so antithetical to its nature that a concentrated dose of them can confuse or even destroy Subject's corporeal systems. This may be why the Mini-Cons pose such a threat to Subject as a group.
  • Incredible physical impacts can still overpower Unicron. The Planet Q was detonated in order to successfully blow up Unicron, but only when it was previously weakened by the combined power of the Mini-Cons.
