Kanjar Ro is an extra-terrestrial conqueror and enemy to the Justice League. Dictator of the planet Dhor in the Antares star system, he is constantly at war with his three neighboring planets. This includes Alstair ruled by the plant-queen Hyathis, Mosteel ruled by the metal-skinned Kromm and Llarr ruled by the lizard-emperor Sayyar. His signature weapon is the Gamma Gong.
