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 swirling, infinite torrent of nothingness at the end of all things. The only thing that he fears is Primus' essence, contained inside the Matrix.
