Character description
Meta Knight is an enigmatic character referred to as Kirby's rival, who often fights with him for different reasons, though they often arrive to the same goal. However, there is some discussion concerning weither or not the two are in another way related. He always wears a white-silver mask, and under it, he looks almost exactly like Kirby, though with a blue body and white eyes. He wears a navy blue cloak (The Dimensional Cape) that can transform into a set of wings, and he usually wields a special sword called the Galaxia Sword (though he gave the "Master Sword" in Kirby & the Amazing Mirror). He follows a code of honor and usually lends Kirby a sword before they fight to be fair. Meta Knight is voiced by Atsushi Kisaichi in Japan, Eric Stuart in the English dub of the anime (Kirby:Right Back at Ya!), and Jay Ward in the English version of Super Smash Bros. Brawl. Meta Knight is often a boss and an ally of Kirby in the series. He first appears in Kirby's Adventure in 1993, where he fights Kirby at the sixth level of the stage Orange Ocean. He also helps to defeat Dark Mind in Kirby & the Amazing Mirror by lending Kirby a mythical sword, giving Kirby the Master ability. He works to keep the chest containing Dark Nebula out of Kirby's hands in Kirby: Squeak Squad. He is the main antagonist of the "Revenge of Meta Knight" mode in Kirby Super Star, in which he attempts to take over Dream Land in order to put an end to the inhabitants' lazy lifestyle. He is a playable character in special modes of Kirby: Nightmare in Dream Land and Kirby Super Star Ultra. He is an unlockable character in Kirby: Canvas Curse and Kirby Air Ride as well, and he uses a combination of the Wing and Sword abilities in Kirby Air Ride. Meta Knight appears in Super Smash Bros. Melee as a trophy, which lacks some of Meta Knight's important characteristics. He also appears as a playable character in Super Smash Bros. Brawl, where he utilizes his sword, Galaxia, as his main weapon. His personal airship, known as the Battleship Halberd, appears in the games Kirby Super Star, Kirby Super Star Ultra, and Kirby: Squeak Squad, Super Smash Bros. Brawl and Kirby's Epic Yarn. Battleship Halberd's inner quarters are filled with enemies and traps arranged to defend against intruders, and its exterior is armed with an impressive array of weapons like the Combo Cannon. Though the Halberd was originally meant to wage war, it appears to be resurrected for the cause of peace. Meta Knight also appears in Kirby's Epic Yarn, where he was sucked into Patch Land and controlled by Yin-Yarn. In Super Smash Bros. Brawl he could flip his cape to reveal another dimension called Galaxia Darkness, and could thrust his sword into a close opponent through it.''
