Raiden Wins comes from Mortal Kombat II, the 1993 arcade fighting game where Raiden, the thunder god, is one of the playable fighters. After a player wins a match with him, the game's announcer declares his victory, a staple of the series' end-of-round presentation. Clips of these announcements have long circulated among fighting-game fans and soundboard users, who reuse them to crown winners in videos, streams and memes. Its staying power comes from that instant recognition: even without seeing the game, listeners know a battle has just been decided.
