The Hadouken debuted as a signature special move in Capcom's Street Fighter series and became world famous with Street Fighter II in 1991. Performed by Ryu and Ken, the move pairs a blue fireball with a shouted attack name, a convention borrowed from martial arts media. Arcade success, home ports and endless sequels turned the shout into shorthand for a projectile attack far beyond fighting games. It is now quoted in memes, remixes and fan videos whenever someone charges up and releases energy.
