100. MODOK

How can you not love a villain whose name is an acronym for Mental Organism Designed Only for Killing? One of the more bizarre looking characters in the Marvel Universe (and that's saying something), AIM technician George Tarleton found himself transformed into a living computer by the group he worked for--with a giant, mutated head, and the need to be fitted into a hover-chair in order to stay mobile.

With mental abilities, comprehension and memory skills far beyond normal men, MODOK quickly proved to be a powerful presence, whose own goals caused him to kill his AIM masters and take control himself. In the process, he became a notable supervillain threat, though one not as strictly tied to a single hero or team as most. Indeed, MODOK has fought everyone from Captain America to Iron Man to Hulk and even Namor and Dr. Doom along the way.

MODOK has returned from the dead more than once and rebelled against subsequent attempts by AIM to once more gain control of him. While his physical nature makes him easy to mock, his mental powers have proven to be deadly for many who have dared cross him. Recently he's been more pro-active than ever, gathering "MODOK's 11" in a scheme that ultimately gave him a new base of operations and followers.
