Hadouken debuted with Ryu in Capcom's Street Fighter arcade game in 1987, as the signature wave projectile performed with a quarter-circle motion and punch input. Performed by Ryu and Ken, the shouted attack became one of fighting games' most quoted moves through Street Fighter II and later sequels, anime and crossovers. Online, editors isolate the shout and add zoom or bass effects to exaggerate its power, which is why this version circulates in meme edits and short gaming clips rather than straight gameplay recordings.
