Conqueror's Haki is a power from One Piece, created by Eiichiro Oda, and it is used by rare characters with overwhelming willpower, including Monkey D. Luffy. The sound became popular in anime editing communities through clips that dramatize haki bursts, knockouts, and aura reveals. It spread across short-form video platforms because viewers immediately recognize it as a shorthand for elite strength and dominance. Even outside One Piece edits, creators use it to frame a moment as untouchable, similar to other anime power cues such as Mangekyo Sharingan.
