Power Ring is de slechte tegenhanger van Green Lantern. Hij heeft superkrachten dankzij zijn ring van Volthoom. Power Ring was een van de zes oprichters van het misdaadsyndicaat die de aarde die ze bewoonden terroriseerden, waardoor de regeringen bijna in de dreiging van een nucleaire oorlog werden gehouden. Hij was een van de leden die de voorkeur gaf aan het gebruik en de ontwikkeling van een kwantumaangedreven kernwapen dat al het leven op aarde zou vernietigen als de aardse regeringen weigerden afstand te doen van de weinig macht die ze aan het misdaadsyndicaat hadden overgelaten.

Captain Super Junior is an evil parallel version of Captain Marvel Junior. He dons a black and yellow outfit, whose motif matches the entire Super family including Superwoman, and has a fierce demeanor. He is one of the Crime Syndicate's Made Men and is a second lieutenant of Superwoman. He has an ability to fly, manipulate weather (that summoning lightning storm), has a superstrength and a basic knowledge of hand-to-hand combat. His true name is never revealed. He works under the call of one of a Syndicate's family heads, Superwoman. In his story on Earth-3, upon the arrival of Justice League from Earth-1, and when Owlman and Superwoman's joint hit on the Justice League base went sour, Superwoman summoned Captain Super, Uncle Super, and him - Captain Super Junior. They failed to turn the tide as Wonder Woman stole Owlman's jet and extracted her allies. Even after the Supers summoned lightning, the jet still got away. Notably, he shattered Green Lantern's constructs with only his strength. A short time later, Owlman drafted Superwoman for a new mission, find the Quantum Trigger in a parallel Earth. Along with the Supers, she teleported into the Watchtower. Junior defeated Firestorm and was about to kill him, when Black Canary knocked him unconscious with a point blank blast of her super sonic Canary Cry. Uncle Super and Captain Super Junior were left behind by Superwoman and Captain Super. It is unknown if they were imprisoned on this parallel Earth or returned to their Earth.
