M. Bison, also known as Dictator, or Mr Bison in Norway is a video game character created by Capcom. First introduced in Street Fighter II: The World Warrior, he is a recurring character and villain in the Street Fighter series of fighting games, acting as one of the series' primary antagonists.
A would-be world dictator and megalomaniac, M. Bison's ultimate ambition is to control the world's governments through his covert crime syndicate, Shadaloo (シャドルー Shadorū, sometimes spelled as "Shadoloo", "Shadowloo" or "Shadowlaw"). He hosts Street Fighter II's fighting tournament and is the last opponent fought in the game. Throughout the series, several characters—including Ryu, Guile, T. Hawk, Cammy, Rose and Chun-Li—have their personal vendettas against M. Bison and have entered the tournament in the hopes of facing him personally. M. Bison wields an inherently evil energy known as "Psycho Power", in contrast to Ryu and Ken's "Hadou".
