M. Bison (Ｍ.バイソン or Mike Bison), known as Balrog outside of Japan, is a character from the Street Fighter series.
M. Bison was once a great boxing champion and prize fighter. He was banned from boxing for permanently injuring his opponents and accidentally killing one (as well as his illegal maneuvers, particularly his headbutt), so he joined the Shadaloo criminal organization, and worked his way up from the bottom, eventually becoming Vega's enforcer.
When Street Fighter II was localized in America, Capcom was afraid of a lawsuit from Mike Tyson over a character with his likeness and a similar sounding name (Mike Bison). They decided to rotate the names of three of the four boss characters in the following manner:
- The boxer is known as M. Bison in Japan and Balrog in the US.
- The Spanish assassin/bullfighter is known as Balrog in Japan and Vega in the US.
- The evil dictator and head of Shadaloo is known as Vega in Japan and M. Bison in the US.
Since we have preference for the source media, use "m_bison" to tag this character on Danbooru.
