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) "". He was also planned to appear in the now-cancelled game "Mega Man Universe". A Ryu-inspired costume for players to use in Sony's "LittleBigPlanet" was released in 2008 as downloadable content for the title. A special downloadable episode in "Asura's Wrath" allows players to fight both Ryu and Evil Ryu. Ryu also appears as a playable character via downloadable content in the Nintendo crossover fighting games "Super Smash Bros. for Nintendo 3DS and Wii U" along with a stage based on his arena from "Street Fighter II" known as Suzaku Castle. Ryu returns in the sequel "Super Smash Bros. Ultimate"
