The Hadouken is the signature special move of Ryu, and later Ken, from Capcom's Street Fighter series, first appearing in the original 1987 arcade game and made famous by Street Fighter II in 1991. The shouted Japanese phrase roughly means surge fist, and the blue fireball became one of gaming's most imitated images. Through arcade culture, tournaments, cartoons and internet memes, the cry spread far beyond fighting games, and creators still use it today as instant shorthand for unleashing hidden power.
