Megatron

Megatron, from the Transformers G1 Universe, is the main emperor of the Decepticons and enemy of the Transformranger. He tried to turn Earth into dark energeon, but it backfired and turned him into a Mobian (Or Sonic character). Although he had been defeated by the Transformranger, he will re-appear in Dave Felis vs Sly Cooper Trilogy in which his Decepticon forces join forces with the Baireno to destroy Cameron and his Transformranger team along with Dave Felis and his Bistoranger team.
