M. Bison

M. Bison, also known as Vega (Japanese: ベガ) in Japan, is a fictional character and the main antagonist of the Street Fighter series created by Capcom. First introduced in Street Fighter II: The World Warrior (1991) as the final boss of the game, he has since become a recurring character in the series, often serving as both a boss and a playable character.

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, 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, while M. Bison routinely sets his eyes on the series' main protagonist Ryu in order to either acquire his power or recruit him for his cause. M. Bison wields an inherently evil energy known as "Psycho Power", in contrast to Ryu and Ken's "Hadou".

In a variety of media, Bison has been portrayed by Raul Julia, Neal McDonough and Silvio Simac and voiced by Tom Wyner, Richard Newman and Gerald C. Rivers. Julia was nominated for a posthumous Saturn Award for Best Supporting Actor for his performance.
