This attack sound comes from Deltarune, Toby Fox's episodic role-playing game and follow-up to Undertale, where powerful enemies and boss encounters give combat a dramatic, story-driven weight. Clips from the game are widely shared on soundboards and in fan edits because their effects are short, recognisable, and easy to place over gameplay, memes, and reaction videos. The Titan attack has become a useful shorthand for a sudden, overwhelming hit, and creators keep returning to it when they need a heavy impact that instantly signals danger, power, and a turning point in a fight.
