The Gaster Blaster comes from Undertale, the 2015 role-playing game by Toby Fox, where Sans summons skull-shaped blasters during his famously difficult boss battle. The shot sound accompanies the blasters firing their beams at the player, and clips of the fight spread widely on YouTube and later on TikTok as the game built a large fan community. Editors and meme creators kept reusing the short blast because it instantly signals an overpowered attack, and it remains a shorthand for a dramatic, unstoppable hit in gaming edits today.
