Blanka

Blanka was abandoned in Brazil as a young boy. Radioactive waste (possibly supplied by M. Bison's Shadaloo organization) transformed him into the man-beast he is today. Blanka is good friends with Dan Hibiki, as they both enjoy rolling, as well as Dan's pupil, Sakura Kasugano. He probably isn't a mutated version of Charlie Nash.
