Meta Knight

Meta Knight is the second arch-rival of Kirby he is a masked being who has a flying ship known as the Halberd. Meta Knight is also the leader of a group called the Meta-Knights (Sword Knight, Blade Knight, Axe Knight, Javelin Knight, Trident Knight, Mace Knight, Captain Vul and Sailor Waddle Dee). He was also a playable in certain Kirby titles such as Kirby Nightmare in Dreamland, Kirby Super Star Ultra  and Kirby's Return to Dreamland. Though he was the primary antagonist of Revenge of Meta Knight in Kirby Superstar, in which he attempts to put an end to the lazy lifestyle of the inhabitants of Dreamland, with the Halberd, he is otherwise either absent or is helping Kirby. His one role as an antagonist stems from good intentions, calling into question his role as a villain.

Kirby's Adventure/ Kirby: Nightmare in Dreamland
Meta Knight's first appearance, albeit unnamed. In this game, King Dedede has split the Star Rod into several pieces to prevent the evil Nightmare from wreaking havoc on Dreamland. King Dedede then recruits Meta Knight and his soldiers, the Meta-Knights, to his cause. Meta Knight would then often send his soldiers after Kirby, probably to prepare him for Nightmare. He later duals Kirby at the base of his operations, Orange Ocean. When Meta Knight loses, his mask is split in two, revealing his face. Meta Knight quickly retreats.

Kirby Super Star/ Kirby Super Star Ultra
Perhaps his most famous role, Meta Knight is the main villain of the sub-game Meta Knights Revenge (this revenge is probably for his humiliating defeat in the previous game). In this sub- game, Meta Knight plans to end the lazy lifestyle of Dreamland by force, using the Halberd. However his plan is foiled by Kirby who defeats him in a duel, destroys the Halberd and escapes on a Wheelie Bike. This is Meta Knight's first and so far, only villainous role.

In the remake, Kirby Super Star Ultra, Meta Knight once again has his own sub-game. This time it is a relevant story. After going trough Kirby's adventures form the original Super Star (excluding Gourmet Race), Meta Knight revives the comet NOVA and, to become stronger, he wishes to fight the greatest warrior in the galaxy, Galacta Knight. He defeats Galacta Knight and is thus, the greatest (technically one of the greatest) warrior in the galaxy.

Kirby and the Amazing Mirror
In this game, Meta Knight has a more heroic appearance. Right from the get-go he flies to the parallel Mirror World to save it from danger, but is instead kidnapped by his evil Mirror World counterpart, Dark Meta Knight. Dark Meta Knight then proceeds to split Kirby into 4 separate Kirby's. When the 4 Kirby's gather all the Mirror Shards, the encounter Meta Knight and his Dark counterpart. The 4 Kirby's defeat Dark Meta Knight and just when their sucked into a portal, Meta Knight tosses his sword into the portal so the Kirby's can fight Dark Mind. He later puts said sword in a pedestal.

Kirby: Right Back at Ya!
Meta Knight appeared as an anti hero in the anime. He assisted Tiff and himself to help Kirby defeat enemies from Nightmare Enterprises that King Dedede has ordered.

Super Smash Bros. Brawl

 * Meta Knight was one of many newcomers in the game. In Adventure mode, He first encounters Marth and has a brief duel with him, but the two quickly joins forces to defeat the Primids attacking them. They later encounter Ike, who becomes their teammate. Later, the three swordsmen meet a robot known as Galleom and defeats him. After saving Lucas and the Pokemon trainer, Meta Knight and the Ice Climbers climb a HUGE mountain, where Meta Knight duals with Lucario. After the dual, they board the Halberd and team up with Snake. After retaking the Halberd, Meta Knight joins the other heroes in the battle against the Subspace Army and their leader, Tabuu.
