Michael "Mike" Corbett is a character from Power Rangers Lost Galaxy. As the one who pulled the Quasar Saber containing the Red Lost Galaxy Ranger powers, he was the one intended to be the Red Lost Galaxy Ranger.

- He is the first hero to morph by calling out his designation/color followed by the word "power", without the word for what he is (defender) or "ranger" (in his own case, "Magna Power"). This is followed by Ryan Mitchell, Eric Myers, and Antonio Garcia.
