M'Dahna has been a Green Lantern for over a millennium and fought alongside its fellow Corpsmen in the war against Krona and Nekron. Following an attack on Krona's forces, M'Dahna held Stel as the robot Lantern slowly deactivated. After the second destruction of the Green Lantern Corps, M'Dahna was one of many powerless Green Lanterns freed by Guy Gardner from an interstellar slave ring. Following the Tristram-Zanner Imperial War, M'Dahna's race disappeared from the cosmos, leaving M'Dahna to patrol its sector while searching for any remains of its people.
