Leo Corbett (played by Danny Slavin) 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.During the Power Rangers Wild Force episode Forever Red, Leo was recruited by Tommy Oliver to journey to the moon with nine other Red Rangers to destroy the Machine Empire. As in his previous appearance, he draws his Quasar Saber to regain his powers. Currently, Leo is living on Mirinoi, either retired and watching over the Quasar Sabers, or active as a Ranger, protecting Mirinoi from threats.It should also be noted that Leo in Latin is lion, which is a coincidence since his main zord is the Lion Galactabeast.His name was likely inspired by the title character of the "Tom Corbett, Space Cadet" stories that were depicted in television, radio, books, comic books, comic strips, coloring books, punch-out books and View-Master reels in the 1950s.
