The Shinkuu Hadouken is Ryu's upgraded super version of the regular Hadouken from the Street Fighter fighting games, a larger, multi-hit energy blast that players save for a decisive moment in a match. Its shouted name and rising power have made it instantly recognisable to fighting-game fans, and clips of the move have spread through gameplay videos, streams and meme edits. It remains popular because it signals maximum effort in just under two seconds, turning an ordinary win, reveal or punchline into a spectacular finish.
