The clip comes from Deltarune, the indie role-playing game by Toby Fox, where the Knight is a mysterious armoured figure encountered as a powerful boss. Its hurt sound is one of the short, punchy battle effects fans clip and share because it is instantly recognisable to players who know the encounter. Once posted to soundboards, it spread beyond gameplay videos into meme edits and reaction compilations, where the roar works even for viewers who have never played the game. It remains useful because it is under a second long and conveys damage, defeat and surprise in a single raw burst.
