Undertale is a 2015 independent role-playing game created by Toby Fox, built around turn-based battles where the player attacks, defends and chooses whether to fight or spare enemies. Its short battle sounds became familiar to a large online audience as playthroughs, edits and memes shared the game far beyond its original players. This attack hit, lasting barely half a second, is now commonly reused in montages and short videos because it instantly signals a successful strike without needing any dialogue or context.
