M. Bison
video game character created by Capcom
M. Bison, known in Japan as Vega (Japanese: ベガ, Hepburn: Bega), is a 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 Šimac 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.
Conception and development
In Japan, the character is named Vega (ベガ, Bega), derived from the star of the same name. However, during localization of Street Fighter II for the English language market, Capcom's North American branch felt that the name did not sound threatening enough to North American audiences for the game's final boss, and thus was more suitable for the Spanish cage fighter.

Why this record matters
“M. Bison” is worth following because a concise public description often conceals a longer documentary argument. Here, Bison, video and game provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q31378. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1991.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
