Luminoth

The Luminoth is a species found in the GameCube video game Metroid Prime 2: Echoes. They are an advanced species who for years traveled the galaxy, finally deciding to make their new hom on the planet Aether after being influenced by the Chozo. Apparently the two peaceful species met each other on an occasion, in which they traded knowledge and technology which would benefit each other.

They lived happily on their new planet, until a meteroite from Phazee crashed onto Aether, thus generating a mysterious new dimension that was later titled Dark Aether, which would in time cause panic among all the inhabitants of the planet once creatures started to imerge from the opposing world via dimensional rifts that were, too, created. The creatures, known as Ing, thankfully evaperated into thin air, though not for long.

Not only that, but the meteroite also caused Phazon to spread throughout the planet, which thus caused the rebirth of Metroid Prime in the form of Dark Samus. The creatures mentioned above eventually found ways to survive the light world, and started to possess many of its inhabitants including some of the Luminoth. Most of the surviving Luminoth, including U-Mos, escaped into the Great Temple, where they were put to sleep until one hopeful day that everything would be restored. U-Mos stayed awake incase any potential threat would arive, though survivial of the species seemed bleak. That is, until Samus Aran arrived on the planet to investigate a missing Galactic Federation ship.

Once the heroic heroine arrived on the planet, she agreed to help restore the power to the Luminoth, and once she did, the species was then capable of defeating the Ing and Dark Samus, and today live peacefully together on Aether thanks to Samus Aran.
