Mace Knight is one of the Meta Knights who serve under Meta Knight himself. He dons purple armor, like his counterparts, with golden shoulder pads and blue shoes. He carries around a mace nearly as big as himself, holding it by the chain.
Kirby's Adventure and Kirby: Nightmare in Dreamland Edit
Mace Knight gangs up on Kirby with the rest of the Meta Knights, appearing as a recurring mini-boss. Meta Knight gives the command upon seeing Kirby, then vanishes, as Mace Knight and the others appear in a surprise attack. Mace Knight swings his mace over his head a few times before thrusting it forward. Then he takes a few steps and repeats. Sometimes, he will swing his mace early if Kirby gets too close. Occasionally, upon spawning, Mace Knight will swing his mace over his head crazily as he dashes across the room. Upon reaching the end, he turns around and proceeds.
'Kirby Super Star and Kirby Super Star Ultra Edit
Mace Knight behaves in the same way as before, but slightly more independent; he spawns without waiting for a command. His attacks are the same, as well.
Mace Knight is also a key character in Meta Knight's Revenge, having his own dialogue throughout the subgame. He is one of the crew-members that watches as Kirby gradually wrecks the battleship Halberd. Despite his witty conversations with others, he also attempts to stop Kirby as he approaches the room where he will encounter Meta Knight, accompanied by others.
