The tone comes from Dragon Ball Super, where Goku first accesses Ultra Instinct during the Tournament of Power arc. The anime pairs the transformation with a distinct shimmering audio cue to mark his shift into autonomous, godlike movement. Editors ripped and isolated the cleanest single hit, and it spread through anime music videos and TikTok edits as shorthand for unlocking hidden power. It endures because it is instantly recognizable to fans and works as a universal power-up signal even outside Dragon Ball contexts.
