Zaltar is a resident of Argo City, a city on the planet Krypton. The city was transported into a pocket of trans-dimensional space at the last second in order for it and it's inhabitants to survive the explosion that destroyed the rest of Krypton. He is the City's Administrator and acts as a mentor to young Kara, showing her the miraculous power source of the city called the Omegahedron, which he "borrowed" from the city government without their knowledge. When Kara lost the Omegahedron by causing it to be sucked out into space, Zaltar took responsibility for the loss by having himself be imprisoned in the Phantom Zone. Later, when Kara as Supergirl was imprisoned in the Phantom Zone, Zaltar risked his life to help her escape in order to confront Selena and defeat her.
