Megalovania was composed by Toby Fox and first appeared in the 2009 EarthBound Halloween Hack before a version was used in Homestuck. It became famous as the final boss theme for Sans in the 2015 role-playing game Undertale, played during the Genocide Route fight. The track spread far beyond the game through remixes, covers, rhythm game charts and meme edits, where its opening riff became shorthand for an unexpectedly difficult opponent. It remains one of the most recognised indie game battle themes online.

Megalovania is the intense boss battle theme for Sans from Undertale, heard when the fight turns serious. Creators use it for epic showdowns and meme battles.
This is a 32-second excerpt of Megalovania, the fast, driving battle track built around a relentless bassline, sharp synth lead and pounding drums. The melody loops with rising intensity, switching between tense low riffs and a heroic, almost frantic main theme. It feels urgent and confrontational from the first bars, like a joke character suddenly revealing overwhelming power. Listeners instantly read it as a final boss moment, which is why even a few seconds can turn an ordinary clip into a dramatic, high-stakes showdown.
