Meta Knight is a masked swordsman from Nintendo's Kirby series, first appearing in the Kirby games before becoming a central character in the anime Kirby: Right Back at Ya!, which aired in Japan in the early 2000s. In the show he often arrives as a mysterious, honourable warrior, and his entrance music quickly became shorthand for a cool, dramatic arrival. Shared widely on soundboards and in fan edits, the short cue still works today because it carries that character's reputation with it, letting creators borrow his authority for a reveal in just a few seconds.
