Zaltar was a mentor to young Kara in Argo City, 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.
- Zaltar was able to create things by using a special wand and then giving it life with the power of the Omegahedron.
