Megalovania is best known as the intense battle theme for Sans in Undertale, released in 2015 and composed by Toby Fox. The melody had earlier appeared in his EarthBound Halloween Hack, but its Undertale boss fight made it a global gaming anthem. Clips, remixes and edits spread across YouTube and TikTok, where creators paired it with showdowns, speedruns and ironic everyday battles. The second version circulating online keeps that same recognisable lead while giving editors a fresh cut for montages, so it remains a shorthand for a high-stakes confrontation.
About this sound
The intense Megalovania 2 track from Undertale, with a fast chiptune melody and heavy drums, often used for boss-fight edits and dramatic gaming montages.
Megalovania 2 is a high-energy, fast-paced instrumental built around a driving chiptune lead, punchy drums and a relentless bassline that keeps rising in intensity. The melody is instantly recognisable, urgent and slightly mischievous, giving even ordinary footage the feeling of a final boss battle. As the tempo pushes forward, it creates tension, excitement and a sense of unstoppable momentum, which is why editors use it to turn a simple reveal, comeback or showdown into something epic. It sounds bold, playful and dramatic at the same time, landing hardest when the action on screen suddenly escalates.
