The sound comes from the lasting popularity of One Piece, Eiichiro Oda's manga that began in 1997 and its anime adaptation that followed in 1999, centred on pirate captain Monkey D. Luffy. Clips of his biggest entrances are constantly reposted in edits, where the cue works like other iconic shonen themes such as Giorno's Theme for signalling a character who changes the whole scene. Fans keep reusing it because Luffy's arrivals mix comedy, confidence and a serious power shift, making the build-up instantly recognisable even out of context.
