Star Blazing is one of Asriel Dreemurr's signature attacks in Undertale, the 2015 indie role-playing game created by Toby Fox. Asriel appears as the final boss of the True Pacifist route, transforming into a godlike form and filling the screen with rainbow stars, chaos busters and lightning. Clips of that fight spread widely through playthroughs, fan animations and remixes, and players began lifting its distinct attack sounds for edits. The Star Blazing cue stayed popular because it instantly signals overwhelming, celestial power in less than two seconds.
