The Meta Knightmare series refers to various sub-games in which the player can play the main game as Meta Knight, usually with a twist of some sort.
- Meta Knightmare, the first occurrence of the sub-game, appearing in Kirby: Nightmare in Dream Land; Meta Knight goes through the main game with half health, the game cannot be saved, but he has many moves at his disposal instead of having only a couple. He does not fight Nightmare.
- Meta Knightmare Ultra, appearing in Kirby Super Star Ultra, in which Meta Knight goes through the main five sub-games of Kirby Super Star; it is the first occurrence of Meta Points, which allow Meta Knight to perform special moves, such as healing or performing a devastating attack. The final boss is Galacta Knight instead of Marx.
- Meta Knightmare Returns, appearing in Kirby: Planet Robobot, in which Meta Knight goes through the main game; Meta Points return, and a few of the special moves have been changed. Meta Knight fights Dark Matter Clone, Sectonia Clone, and Galacta Knight instead of Star Dream.
