6. M. Bison – “Street Fighter II”
The first rule of video game bosses is never under estimate a man in a cape. Look no farther than M. Bison, the final boss of “Street Fighter II,” as evidence, whose mixture of muscle and “Psycho Power” made him one of the most feared fighters in the franchise. It’s never even been revealed what the M stands for—although the name began as Mike Bison, a parody of Mike Tyson—adding to the mystery of this white-eyed military man.
