The Roaring Knight is an enigmatic armored figure from Toby Fox's Deltarune, a character fans latched onto as a symbol of the game's darker mysteries. Because Deltarune has no voice acting, this laugh is not official game audio; it circulates as a fan-made meme clip that the community attached to the Knight. It spread through boss fight edits, theory videos and gaming memes, where a single cold cackle instantly sells menace. That is why it endures: it gives creators a ready-made villain laugh for a character who never speaks.
