Galaxia

Galaxia is Meta Knight's sword, which was created near after the beginning of the universe.

Appearance
It is golden in appearance, with a blade about as long as Meta Knight himself is tall, with a single rounded or oval ruby set within its hilt. Its handguards point towards the blade, which has a mirror-like, polished appearance compared to the hilt. There are usually six spikes along its blade, although there can be anywhere between zero to eight depending on artwork, and they range from simple outward pointing spikes to ones which have a slight outwards curve to them, similar to a fiery pattern.

As portrayed in the anime, Galaxia's blade has the unique property of only phasing into existence once it is unsheathed. This makes its sheath very short - a simple shallow cup for the small part of the hilt extending above the sword's handguard, which avoids encumbering Meta Knight's movement. The phasing blade also explains the Hammerspace (magic satchel) effect where Meta Knight seemingly produces a sword longer than himself from out of nowhere in the games.

History
In Kabu's own words, Galaxia is a powerful sword forged by Photron, the mighty ruler of the fire people (people of light in the Japanese version), "in a time long forgotten, thousands of years ago when the universe was young", created "with a will and life of its own". Galaxia's name was given by Photron himself, but for what purpose it is forged for, and who was its intended wielder was never revealed.

Nightmare Enterprises sent Kirisakin to steal the sword hide it away in a dark cave, and guard it throughout the millennia that will come to pass until it is seen again. According to Kabu, possession of Galaxia gives eNeMeE the power to control the universe, but how, he did not elaborate. The sword did lie dormant in the cave for a long time, so despite what Kabu had said, eNeMeE must have had difficulties harnessing the sword's power; since if he had, he would have succeeded in his goal of ruling the universe millennia ago.

Meta Knight and Garlude retrieved the sword, though Garlude's life was taken by Kirisakin in the process. Garlude's daughter Sirica came to Dream Land misled to the fact that Meta Knight stole Galaxia and left Garlude to be killed by Kirisakin. During a fight with Kirisakin, Sirica touched the sword twice and it found her unworthy to wield it and shocked her. It then contacted her mind and revealed the truth, so she flung it to Kirby, who used it as Sword Kirby to defeat Kirisakin for the second time since WolfWrath.
