Unicron is the overarching antagonist of the Transformers series. Unicron made his debut in the 1986 animated movie of Transformers, where he was a devourer of worlds.


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, with the only goal of ending the entire creation no matter what cost.

Powers & Abilities

  • Master Manipulator: Unicron is able to manipulate other beings by making unfair deals with them, and giving them powers. However, he also desires to consume them.
  • Transforming: Unicron is able to transform himself. He is a deity but can turn into a giant mechanical robot which can transform into a world which consumes other worlds.
  • Consumption:' Unicron, in his planetary form, can consume entire worlds and all the life living on them. In The Transformers: The Movie, he was also able to consume Galvatron in his robotic form, simply by picking him up and dropping him into his mouth.
  • Immortality: Due to him being a deity like Primus, Unicron is immortal, and cannot die of old age.
  • Flight: Unicron is capable of interstellar flight.
  • Cosmic Awareness: Unicron can sense things across dimensions and knows/sees what happens across the universe at any time. He even witnessed the death of Optimus Prime and saw who inherited the Matrix, despite not being present for the event.
  • Matter Manipulation: Unicron is able to manipulate matter in various ways, such as converting it into energy, creating armies of heralds, and transmuting Megatron and his Deceptions, completely reshaping their bodies in the process.
  • Telepathy: A fragment of him was powerful enough to attack the minds of an entire population. He was also able to physically mutate the population. He anipulates Galvatron's mind and talks to him telepathically. In Transformers Prime, Unicron manipulates Megatron to act as his vessel.
  • Eye Beams: Unicron can shoot beams from his eyes that can one shot ships.
  • Fire Breath: Unicron can breathe fire that could blow chunks off of giant metal ships.
  • Power Inducement: Unicron can grant power to others, as shown when he gave Megatron new abilities when he changed him into Galvatron.
  • Dimensional Travel: Unicron can move through dimensions by traveling through black holes, and traverses different realities to consume them.
  • Size Manipulation: Unicron is shown to be capable of increasing his size at will. Some versions are as big as Primus' moons, while other versions are as big as Earth itself. In the Marvel Comics, he was as big as Saturn.
  • Body Transfer: Unicron can make other planets his new body if his old one is ever destroyed. He was going to make Cybertron his new body though he requires help from another being for this process
  • Resurrection: Unicron can resurrect others from the dead, as he did with Starscream. In Transformers Prime, he brought back Megatron to act as his vessel. He is also able to create life and dark worlds.
  • Dark Energon: In Tranformers: Prime, his blood has the power to raise the dead. When Megatron injected himself with Dark Energon, it gave him the ability to control those resurrected by Dark Energon. Unicron can create weapons made from energon such as guns, hammers, javelins, and scythes.
  • Incorporeal: In Transfromers Prime, he can come back as a non-corporeal after being defeated by the Matrix to possess Megatron.
  • Reality Warping: Unicron can consume spacetime itself, create pocket dimensions and universes, and  summon beings from different points in time and space. In the Cybertron cartoon, his death created a black hole that threatened the multiverse.


  • Anti-Bots: These bots are Unicron's own internal defense system. They are a swarm of floating mechanical creatures that attack all foreign bodies.
  • Drones: Unicron can unleash a seemingly endless horde of simple drones to fight for him.


  • Planet Mode: Unicron's transformation is an entire planet. It can range from being as big as half of Earth or as big as Saturn. In this mode, Unicron can consume entire planetary bodies by using a tractor beam. Inside of his body are numerous defenses, such as retractable claws attached to cables.

  • In the Dreamwave Armada comics, he ravaged one universe and its Cybertron and almost destroyed another version.
  • In the Armada cartoon, he impersonated one of Cybertron's moons and created the Mini-Cons to increase the conflicts of the Autobot/Decepticon War.

  • Is responsible for Transformers Energon.

Fun Facts

  • Although Megatron/Galvatron is responsible for driving the entire plot of the Transformers series, Unicron is shown to be the most dangerous villain, because he would choose to destroy Cybertron (and all reality) rather than taking it over.
  • Although Unicron was originally going to appear in Transformers: Age of Extinction as the main antagonist, he was replaced by Harold Attinger. However, Unicron would serve as a minor antagonist in Transformers: The Last Knight, where it was revealed that he was (similarly to his Prime counterpart) the Earth itself.
  • It is unknown what Unicron's origins are in the Transformers Cinematic Universe, either being a giant robot, or an evil deity. However, due to Unicron being the core of Earth (and Primus being the core of Cybertron) in Transformers: Prime, the latter seems more likely to be the case.
  • In 2004, Unicron was said to be a "Multiversal singularity", meaning that in all universes, Unicron was the same dimension hopping entity, despite their different origins. However, due to how complicated the concept was, it was eventually written out in 2015.
