About this sound

The iconic Gaster Blaster attack sound from Undertale, used in memes, gaming edits and dramatic moments when a sudden powerful hit lands.

This clip is the sharp, explosive attack sound associated with the Gaster Blaster in Undertale, most commonly linked with Sans and fan battle edits. It starts with a tense energy and bursts into a forceful beam-like blast that feels sudden, dangerous and overpowered. Because it is short and instantly recognisable to many game and meme fans, it works well as a punchy cue for impact reveals, impossible dodges or moments when a character suddenly turns the fight around. The sound gives a scene immediate intensity and a chaotic, boss-battle feel.

The Gaster Blaster sound comes from Undertale, the 2015 indie game by Toby Fox. It is closely associated with Sans and the game's attack-heavy fan content, where the skull-shaped blasters became a standout visual and audio element. Over time, the clip spread through YouTube edits, animation memes and gaming compilations, especially in power-scaling jokes and dramatic battle scenes. It remains popular because even a very short burst instantly signals danger, speed and an over-the-top special attack to players who know the game.
