The Hadoken is Ryu's signature special move in Capcom's Street Fighter series, first introduced in the original arcade game. Performed with a quarter-circle motion, it sends a surge of energy toward an opponent and has remained part of Ryu's moveset in almost every sequel. As Street Fighter became a global fighting-game staple, the shout and blast became shorthand for a powerful projectile attack. Online creators later adopted the short clip for memes, reaction videos and edits, where its instant recognition does much of the comedic work.
