Sans first appeared as the easygoing skeleton in Undertale, Toby Fox's indie role-playing game, and his battle theme Megalovania helped turn him into one of gaming's most recognisable characters. Fans later embraced him in Super Smash Bros. Ultimate, where he appeared as a Mii Fighter costume, and victory-style edits pairing his theme with Smash gameplay spread across meme and gaming communities. The clip endures because it compresses that underdog triumph into a few seconds, making it an instant shorthand for beating an opponent who seemed unbeatable.
