This is a list of fictional characters in the Power Rangers universe appearing in the television series Power Rangers Lost Galaxy.
The Galaxy Power Rangers gained their powers through use of the Quasar Sabers - five ancient swords that were discovered on the planet Mirinoi. At the beginning of the series, the Quasar Sabers were pulled from a block of stone (mirroring the legend of Excalibur), thus highlighting the youths as the modern day chosen wielders of the weapons (that is, with the exception of Leo Corbett, whose Saber was given him by his brother Mike).
The Galaxy Power Rangers protected the space colony, Terra Venture, from the machinations of alien villains Scorpius, Trakeena and Deviot. This was the first (and so far only) incarnation of Power Rangers that did not have some connection to the Earth, save that they departed Earth in the first episode.
Leo Corbett was a stowaway aboard the space colony. He wanted to follow his soldier brother Mike, to find a new world. He largely witnessed the discovery of the Quasar Sabers by accident. Mike originally drew the Red Quasar Saber, but passed it on to Leo before falling to his apparent death at the bottom of a crevice. This allowed Leo to morph into the Red Galaxy Ranger.
Throughout the series, Leo used weapons and tools such as the Magna Talon Transdagger, Lion Galactabeast, Red Astro Cycle, Armor Keys (which he used to become the Red Armored Ranger), Red Capsular Cycle (which he gained through understanding his Galactabeast), and the Lights of Orion. When the Magna Defender died and Mike was freed, Leo considered giving his powers and Quasar Saber back to his brother, but Mike said it was Leo's destiny to become the Red Ranger.
In the finale, Leo single-handedly destroyed Trakeena in her green insectoid form, sacrificing his Battlizer in the process. Leo blasted Trakeena at point-blank range, destroying his armor and nearly destroying himself. When Triskull and his ghouls invaded Mirinoi, Leo took on the mantle of Red Ranger once more, and followed him to Earth, where he helped the Lightspeed Rescue Power Rangers defeat him and Trakeena. Leo is shown to be able to draw his Quasar Saber from the stone, something he had never done.
