Unicron
Unicron is a fictional villain from the Transformers media franchise. Designed by Floro Dery, he was introduced in the 1986 animated film The Transformers: The Movie and has since reappeared in Transformers: Armada, Transformers: Energon, Transformers: Cybertron, Transformers: Prime, Transformers Prime Beast Hunters: Predacons Rising, Transformers: The Last Knight, Transformers: Rise of the Beasts, and Atari's 2004 Transformers video game. Unicron is a prodigiously large robot whose scale reaches planetary proportions; he is also able to transform into a giant planet. Unicron's origin has expanded over the years from simply being a large robot to being a god of chaos who devours realities. He often employs the help of Decepticons in his work, and in some stories is considered part of the origin of the Decepticon forces.
