Hadouken is Ryu's signature fireball attack from Capcom's Street Fighter series, made famous in Street Fighter II in 1991 and shouted by the character himself in game. This Portuguese version, credited to Mundo Canibal, reframes the move as a fan yelling the command at Ryu, which helped it circulate on Brazilian soundboards and gaming pages. Its mix of nostalgia, Brazilian humor and a universally recognised special move keeps it in use for fight edits, streams and meme reactions long after the original games.
