An insane, hyper-intelligent criminal mastermind who led a group of renegade Predacons to Earth in search of the Energon they would need to conquer Cybertron, Megatron became so much more than a petty felon. He launched an assault to Time itself, seeking to change history to his benefit. He nearly destroyed Cybertron in his mad quest to exterminate the Transformers, and he was stopped only when Optimus Primal brought him down. Now, he has returned, and his battle with the Maximal leader rages across the multiverse.
