Seisan Seisan The karate kata (alternate names Sesan, Seishan, Jusan, Hangetsu) literally means '13'. Some people refer to the kata as '13 Hands', '13 Fists', '13 Techniques', '13 Steps' or even '13 killing positions'. However, these names have no historical basis. Seisan is thought to be one of the oldest kata, being quite spread among other Nahate schools. Shito-ryu has its own version and different versions are now practised even in Shuri-te derivatives like Shotokan (called Hangetsu) and in Wado-ryu (called Seishan). Isshin-ryū also adopted this kata. This kata is also practiced in Korean styles such as Tang Soo Do and
Ryu (Street Fighter) and brainwashes Ken in Ryu's stead, which prompts Guile and Interpol to intercept Ryu before Bison can get to him, but Bison follows them and sets Ken on Ryu, who refuses to fight his controlled friend back. Eventually, Ken manages to break free of Bison's control and the two ultimately work together to defeat Bison. The final scene, however, makes it clear that Bison survived, and he ambushes Ryu, who prepares to fight him again. He was voiced by Kōjirō Shimizu in the Japanese version and Skip Stellrecht in the English dub. Ryu also appears in the American TV series
