Galaxia

From SmashWiki, the Super Smash Bros. wiki

The Galaxia is Meta Knight's sword. Like Link's Master Sword, it is Meta Knight's weapon of choice.

Curiously, Meta Knight's sword was never named in any game in the Kirby series. Kirby uses Meta Knight's sword to fight against the final boss in Kirby and the Amazing Mirror. This form in the game is called the "Master Ability".

In the anime, Kirby: Right Back at Ya! known in Japan as Hoshi no Kirby (星のカービィ, Hoshi no Kābī, lit. "Kirby of the Stars"), the sword is finally given a name, Galaxia, and only a selected few can wield it. In the anime, the only power the sword is shown using is called the Sword Beam. It was a solid blast that could shatter rock. However, this power is presumably anime-only.

• Galaxia Darkness is the name of Meta Knight's Final Smash, pertaining to the sword.

[edit] Master

Master is the name of the ability Kirby recieves while wielding Meta Knight's sword in the Gameboy Advance Game, Kirby and the Amazing Mirror. It is an unlockable ability with no hat, and can only be used in the main world after the final boss has been defeated (it is also used during the final boss fight).

Meta Knight wields the sword Galaxia in Brawl, although it takes its appearance from the anime and Kirby: Air Ride as opposed to Kirby and the Amazing Mirror itself. Meta Knight's Forward B in Brawl, the Drill Rush, may be derived from a similar move that can be used when Kirby has the Master ability.
