Hadouken is the signature fireball attack of Ryu, and later Ken, from Capcom's Street Fighter series, first released in 1987. The move became one of the most recognisable attacks in fighting games, with its shouted name and projectile entering wider pop culture through sequels, animated adaptations and competitive play. Online, the sound is now reused far beyond gameplay, appearing in reaction videos, gaming montages and comedy edits where an ordinary action is framed as a powerful special move.
