Unicron

Unicron is the overarching antagonist of the Transformers franchise. He is a giant cosmic Cybertronian god who serves as a multiversal singularity desiring to find peace by consuming and destroying all reality around him, as well as the twin brother and arch-nemesis of Primus, the creator of the Transformers.
