Hadouken debuted as Ryu and Ken's signature projectile attack in Capcom's Street Fighter series, first appearing in the original arcade game in 1987. The shouted attack name became one of gaming's most quoted move calls as Street Fighter II popularised fighting games worldwide in the early 1990s. Clips of the sound spread through arcade culture, home ports, remixes and later meme videos, where the short blast works without context. It remains popular because it instantly signals power, nostalgia and over the top action.
