About this sound

The intense Megalovania theme from Undertale, sped up for hard mode battles. Creators use it for epic boss fights, gaming edits and high energy moments.

This is a short, high intensity version of Megalovania, the driving electronic rock theme built around a fast bassline, sharp synth lead and relentless drums. The hard mode edit pushes the tempo and aggression, making every beat feel urgent and confrontational. In a video it instantly signals a serious challenge, a final boss or a character who is far more dangerous than they look. The melody is repetitive in a good way, looping in the head and building tension without needing any vocals or dialogue to explain the stakes.

Pro tip

Drop the first beat exactly on the reveal or attack, then let the loop run under fast cuts without extra music. Keep dialogue low in the mix because the synth lead is very forward, and cut out before the repetition gets tiring.

How people use it

Adding intensity to a difficult gaming boss fight montage.
Scoring a character reveal as an unbeatable final opponent.
Editing anime battles where the hero is completely outmatched.
Punctuating memes about trying something on hard mode difficulty.

More information

Megalovania was composed by Toby Fox and appeared in earlier forms in the EarthBound Halloween Hack in 2009 and in Homestuck before becoming famous in Undertale in 2015. In Undertale it plays during the Sans boss fight on the genocide route, which turned the track into a symbol of a deceptively tough opponent. Remixes, harder arrangements and instant button versions spread widely through gaming videos and memes, and the opening riff is now recognised by many players even outside the original game.
