ペガサス is simply the Japanese katakana rendering of 'Pegasus,' and the clip has lived mostly as an anonymous upload passed between anime edit communities rather than a documented scene from a known series. Its staying power comes from utility: the winged-horse myth is instant shorthand for flight, freedom and triumph, so editors reach for it whenever a moment needs wings. It circulates alongside other anime meme sounds like Tuturu, the dramatic time-stop moments of Za Warudo edits, and the to be continued cliffhangers that close out JoJo compilations, each one a ready-made emotional cue.
