Shadowlaw an underground organization bent on world domination through drug smuggling, illegal weapons distribution and terrorism. Led by the evil M. Bison (Vega in the Japanese version), Shadowlaw hopes to increase their power by recruiting the world's greatest street fighters. Their main target: Ryu a master of Shotokan Karate who roams all over the world to test his skills against other fighters. As a means to lure the elusive Ryu, Bison abducts his best friend, former martial arts champion Ken Masters, and uses him as bait. Interpol agent Chun-Li and U.S. Air Force pilot Guile team up to get to Ryu before Bison does and continues his reign of terror.
