White Zangetsu is the hollow manifestation of Ichigo Kurosaki's Zanpakuto spirit in Bleach, the long-running anime and manga series, and he appears whenever Ichigo confronts the darker side of his own power. Fans lifted the tense audio cue associated with his appearances for short edits, reaction videos and power-scaling clips, where it signals that a character is no longer holding back. Like other dramatic anime moments such as Mangekyo Sharingan reveals, it works because viewers instantly recognise the shift toward something dangerous, which keeps it popular in Bleach edits years after the original scenes aired.
