Meta Knight can't be classified as a good or bad person. In fact, GamesRadar named him "The 12th Most Misunderstood Videogame Character" and "The 7th Unluckiest Badass in Gaming." His feelings towards Kirby have never been directly stated either. So far, he has only played a role as an antagonist in the game Revenge of Meta Knight. This is the game that catapulted him into Videogame fame, yet had earned him a bad reputation.
One of Meta Knight's most obvious features is that he always wears a mask. In most of his games, however, his mask breaks off once you defeat him. This reveals his true face, that looks very similar to Kirby's, except for that his skin is blue and his eyes are white. It is a common assumtion that he is a member of Kirby's species, though this has never been confirmed. But given the odds, this is very likely. Once his mask breaks off, he immediately vanishes into his cape and departs.
Meta Knight is very skilled in swordplay, and thus most of his attacks are based on it. He also uses attacks that aren't necessarily based on it, like Sword Beam, a very powerful move. He is also capable of summoning giant tornadoes, a move known as Mach Tornado. He can also fly, and in most of his playable appearances, he has part of Wing's moveset. Lastly, he is able to warp using his cape, reffered to as the Dimensional Cape. He usually uses this attack when his face is revealed or he knows he has been defeated, but in Super Smash Bros. Brawl, he uses it as an attack.
He made his debut in the second installment in the series, Kirby's Adventure. In this game he will give Kirby Invincibility Candy yet he will occasionally summon his soldiers to fight against you. Once you reach Orange Ocean, he will finally fight you. Beating him gives you the penultimate piece of the Star Rod.
Revenge of Meta Knight is Meta Knight's most important role in the Kirby series to date. He got his own sub-game with him as the prime antagonist. Meta Knight and his army, the Meta-Knights, had planned to take over Dream Land to "end the residents' lazy lifestyle." To ensure this, he and his crew built Battleship Halberd. However, Kirby noticed this and flew in to destroy it. After being blown off-course a few times, the pink hero downs the warship before any harm could be done.
This sub-game, appearing only in Kirby Super Star Ultra, allows you to play through all the original sub-games (except for Gourmet Race ) as Meta Knight. It's like its predecessor, Meta Knightmare, but the story is slightly different. Interestingly enough, he goes through Revenge of Meta Knight and destroys the Halberd. No explanation is ever given for this. In this one, he doesn't fight himself like in the original, though.
In this game, you can K.O. foes and store power and use these moves:
Mach Tornado: Send two tornados across the screen to damage all enemies. It is similar to crash. (30 pts)
The boss of the Milky Way Wishessegment is not Marx. It is Galacta Knight, a warrior sealed away long ago for fear that his powers were too great. Meta Knight wishes to challenge him in order to become the greatest warrior in the galaxy, so he asks NOVA to fight him.
In the anime, he is known as a Star Warrior and strangely knows almost everything about Kirby.
Meta Knight wields a legendary sword called Galaxia. There is a lot of history on this blade coming from the anime. In the anime, Meta Knight has a Spanish accent and Spanish background music whenever he appears. Considering these facts, he is possibly a reference to Zorro.
He only appears in Super Smash Bros. Brawl out of the three games, although he was planned to be a playable character in Super Smash Bros. and Super Smash Bros. Melee. In general, his attacks are very fast, (he isn't called Meta Knight for no reason) but somewhat weak. All of his special moves allow him to recover, but will leave him in his "helpless" state if done in the air. Considering this, though, he has been considered a broken character and is sometimes banned in tournaments.

Meta Knight appears as a boss inKirby's Epic Yarn. He was surveying Dream Land's alarming changes, when suddenly Yin-Yarn ambushed him, turning him into yarn and posessing him so that he would attack Kirby. He is fought in Space Land
In the battle against Meta Knight, you attack him by throwing yarn balls at him. You get them with the sword beams he fires, and when he is in a vulnerable position, throw them at him! He doesn't use his sword Galaxia in this battle, but instead four yarn swords. Each of them have a new power.
