Hadouken began as the signature fireball attack of Ryu in Capcom's Street Fighter series, performed with a forward hand thrust that sends a surge of energy toward an opponent. The move and its shouted name became one of the most recognisable elements of fighting games as Street Fighter grew from arcades into home consoles and competitive play. Over time, clips of the sound spread through gaming videos, memes, and reaction edits, where it is now used far beyond actual gameplay. Its staying power comes from instant recognition: even people who have never played Street Fighter know what the shout signals.
