Yoshimitsu debuted in the original Tekken in 1994 as a mechanized ninja with a distinctive sword fighting style. His seppuku, also called harakiri in move lists, became one of his signature risky techniques, harming himself while potentially catching an opponent close behind him. Clips of the vocal grunt and blade sound were later ripped from the games and shared on soundboards, where the move's over the top self sacrifice made it a reusable reaction for defeat, embarrassment and intentional self sabotage online.
