Megalovania is a track by Toby Fox that became widely known through Undertale, released in 2015. The opening notes are especially famous because they instantly cue the song before the full melody begins, making them perfect for short meme edits and reaction clips. Online, creators use this tiny musical sting to suggest a surprise battle, a sharp difficulty jump, or any moment that feels like a dramatic game encounter. Its staying power comes from how quickly fans recognize it, even in a clip lasting less than a second.
About this sound
A short clip of the opening four notes of Megalovania from Undertale, used in memes and edits to instantly signal a Sans fight or dramatic reveal.
This clip is just the instantly recognizable opening four notes of Megalovania, the battle theme most closely associated with Sans in Undertale. Even in under a second, the punchy synth notes create immediate tension and recognition for anyone who knows the game or its meme life online. The sound works like a musical jump cut: it can turn a normal moment into a fake boss battle, a sudden challenge, or an overblown reveal. Because the phrase is so short, it lands fast and usually gets the joke across before the next visual even appears.
