Worldsmith appears in Deltarune Chapter Rewritten, a fan-made reimagining of Toby Fox's Deltarune rather than an official chapter, and this roar is associated with his character in that project. According to the original upload, his fight has not been released, so the clip circulates mainly as a teaser sound for fan edits, trailers, and boss concepts. Its short length makes it easy to drop into videos, and fans keep using it because it gives an unreleased antagonist an immediate, intimidating presence without needing dialogue or context.
