Unicron
Unicron is a fictional character from the Transformers universe and toyline. Created 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, and Atari's 2004 Transformers video game. Unicron is a prodigiously large robot whose scale reaches planetary proportions, and he is also able to transform into a mechanical 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.
Fictional character biography
According to the Transformers lore, before the dawn of time, Order and Chaos existed within an extra-dimensional entity known as The One. To explore the fledgling 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 universe at a time, moving freely between them at will, Primus existed simultaneously in all realities at once. It is suggested, in fact, that the two brothers embodied the basic concepts of reality—good and evil, order and chaos—and that their continued existence is necessary for the stability of the storyline multiverse itself.
