Megalovania was composed by Toby Fox for Undertale, where it plays during the battle against Sans, one of the game's most famous encounters. Its relentless rhythm and memorable melody helped it become a fan favourite long after the game's 2015 release, and it later appeared in Super Smash Bros. Ultimate as part of the Undertale content. Online, the track is closely tied to determination, final battles and characters who refuse to lose, which keeps it in constant use for edits, remixes and reaction videos.
About this sound
The fast, intense Megalovania theme from Undertale, as heard in Super Smash Bros., used for dramatic boss fights, intense reveals and high-energy meme edits.
This is a short, high-energy burst of Megalovania, the driving chiptune battle theme associated with Sans in Undertale and later featured in Super Smash Bros. Ultimate. Pounding drums, a frantic bassline and a sharp, looping melody hit almost instantly, with no slow build-up, giving it a tense, confrontational edge. It sounds urgent and slightly unhinged, like a final boss fight starting mid-swing. That instant intensity is why creators drop it over sudden confrontations, dramatic entrances and moments when an ordinary scene suddenly turns into a showdown.
