Hadouken

The Hadouken or Hadoken (literally “wave motion fist” or “fist of surge”) is a special attack from Capcom’s Street Fighter series of fighting games. Game designer Takashi Nishiyama credits an energy attack called Hadouho (lit. the “Wave Motion Gun”), from the 1970s anime Space Battleship Yamato, as the origin of Hadouken. It is used by the characters Ryu, Ken, Sakura, Akuma (Gouki in Japan) and Gouken. The Hadouken and the Shoryuken are the two archetypal moves of these characters, as well as some of the most iconic and famous elements of the Street Fighter series or even video games in general.
