Galaxia

Galaxia is the name of Meta Knight's sword. It has appeared in every one of MK's appearences, but wasn't named until the Kirby: Right Back at Ya episode Crusade for the Blade". Despite appearing alongside Meta Knight in virtually every early game he appeared in, the sword was never properly named until in Kirby: Right Back at Ya!. In Kirby: Right Back at Ya!, Galaxia may only be wielded by a select few. Here the Galaxia was shown to have virtually all moves by Meta Knight used in the past games, including the sword beam attack which appeared in Kirby Super Star (albeit smaller and weaker) . In the anime, the beam takes the form of a concentrated blast powerful enough to shatter rock, create crevasses in the ground, and slice opponents in two. Galaxia is also unique in the fact that it emits a powerful consciousness. It can only be claimed as one's own by one who possesses enough power to hold it. Those who are not chosen can either end up being harmed or killed by the sword's overwhelming electric energy, or end up infusing evil upon themselves. The only game to refer to this sword so far is Super Smash Bros. Brawl, where Meta Knight's Final Smash is called "Galaxia Darkness". In Kirby Right Back at Ya!, Galaxia was shown in the episode Crusade for the Blade. It was made by the fire king long ago, and N.M.E had sent Kirasakin the Great to steal the sword. However, Meta Knight, and mother of Sirica, Garlude, arrive. Garlude distracts Kirasakin, while Meta Knight gets the sword, Galaxia, and is the "Chosen One". He destroys Kirasakin to find that Kirasakin returns, while Kirby sucks up Galaxia and ultimately destroys the evil monster.

Master
Master is the name of the copy ability Kirby gets when Kirby inhales MK's sword in Kirby and the Amazing Mirror. It is unknown whether it is the same sword as galaxia. It has many of the same moves, such sword beam and drill rush.
