The Galaxia is Meta Knight's trademark sword. Its overall shape is flame-like, the blade itself being colored a golden hue, with a ruby on its hilt. Meta Knight has shown to be able to send out sonic booms with this sword as well as utilizing it for more conventional uses, such as slashing and cutting. The name Galaxia first appeared in the Kirby anime. Since then, many games have shown Meta Knight's sword to resemble the one from the anime, indicating that it is the same sword. It was finally proven that Galaxia is the name of his sword in the games in Kirby's Epic Yarn, where there is an item called the Galaxia Sword on the Halberd.
Kirby's (Extra) Epic Yarn
The Galaxia appears as a furniture item in Kirby's Epic Yarn and its remake. The furniture piece, named the Galaxia Sword, depicts the Galaxia rested upon a wooden stand. It can be obtained early in the Battleship Halberd stage.
Kirby Mass Attack
In Kirby Mass Attack, the Galaxia appears as a secret boss in Chapter 4 of the sub-game Kirby Quest. If the player does not miss a single attack for the first 8 battles of the chapter (and if they have beaten the chapter before), Meta Knight is replaced with an oversized Galaxia as the boss for stage 39. The Galaxia has 2500 health and, once defeated, grants Kirby the ability to perform an Excellent attack in which he wields the sword. The attack deals 9999 damage and is thus capable of instantly defeating any enemy or boss in Kirby Quest.
In Kirby: Right Back at Ya!
|My name is Galaxia. Only the most powerful of knights may wield my ancient magic. Meta Knight is the chosen one. Your mother Garlude knew well this truth. In sacrificing her life, Garlude made the ultimate sacrifice.|
— Galaxia addressing Sirica in Crusade for the Blade
In the anime series Kirby: Right Back at Ya!, the Galaxia is Meta Knight's signature sword, and an ancient relic of great power. The Galaxia appears prominently in the episodes Hour of the WolfWrath and Crusade for the Blade. In the latter episode, the Galaxia is told by Kabu to have been forged thousands of years ago by Photron - the king of the Fire People - and imbued with a life of its own, but it was later stolen by the monster Kirisakin in order to safeguard it for eNeMeE. In order to recover this sword, the Star Warriors Meta Knight and Garlude (the mother of Sirica) fought Kirisakin to reclaim it, but Garlude ended up having to sacrifice her own life to toss the sword to Meta Knight, who among them was the only one who could wield it.
The Galaxia is described as being so powerful that it could decide the fate of the universe, so Meta Knight takes extra care to ensure it does not end up in the hands of Night Mare Enterprises. The sword has the power to reject those it deems unworthy who try to wield it by shocking them with electricity. Though Meta Knight is described by the Galaxia itself as the chosen one, it is clear that its true potential can only be unlocked when it is wielded by Kirby. Using this sword as a proper Copy Ability, Kirby gains the power to toss devastating Sword Beam attacks which can cleave in two even N.M.E.'s most formidable monsters.
