Balrog, named as M. Bison in Japan, is depicted as an African-American boxer wearing blue trunks with white trim and a torn white shirt under a blue tank top, who made his debut in Street Fighter II: The World Warrior as the first of the games' four bosses. He wears red boxing gloves and boxing shoes. His hairstyle consists of short hair cut in an odd pointing style in the front, similar to Mike Tyson's haircuts from the time Street Fighter II was made. Although usually removed when these illustrations are published outside Japan, some character illustrations feature his Japanese name, "Bison" on the waistband of his trunks. In Street Fighter IV, the waistband now reads "Champion". In Japan, the character of Balrog is named M. Bison, with the letter being an initial for "Mike", and is intended as a parody of real-life boxer Mike Tyson. However, when the game was to be ported for worldwide audiences, under the suggestion that the character's name and likeness resembled Tyson to the point of infringement, the developers rotated the names of three of the boss characters for the English localization. As they felt the name Vega was better suited for the androgynous bullfighter, they gave him the character's previous name, Balrog, and changed the name of the game's final boss to M. Bison.
