The Roaring Knight is the mysterious antagonist in Deltarune, Toby Fox's episodic role-playing game, linked to the creation of Dark Fountains and the coming Roaring. Interest in the character surged as new chapters expanded the boss encounters, and short audio cues from those fights began circulating in edits, streams and soundboards. This jump cue became a reusable shorthand for a menacing entrance, separate from longer boss themes. Fans keep using it because it instantly signals danger and dark fantasy energy without needing any dialogue or setup.
