Unicron (Transformers)

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 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.
