Game: Bionic Commando
What Makes Them Bad: Trying to control the world.
What Makes Them Cool: His face explodes rather nicely.

The guy very closely resembles Hitler, does he not? Originally this Bionic Commando endboss was meant to be the reanimated corpse of Hitler, but North America got Master-D, who's felled by a satisfying explosion of brains, blood, and ocular orbs that bucked any tradition of "tame" we'd seen back in the NES days. Take that, Hitler zombie!
