Hippolyta Trevor and Beautia Sivana, daughters of famous and infamous individuals from the 1940's. But they were more than just the female offspring of the heroic Wonder Woman and the nefarious Doctor Sivana. They, along with the main men int their lives, were brave offspring that reached the pinnacle of perfection.
Though not possessing the physical mighty of her counterpart Lyta, aka Fury, Beautia's brother Magnificus more than made up for that with superstrength. This was displayed in full force when Sivana's son battled with Captain Marvel, and then was quickly dispatched. And Magnificus' cosmic twin was Hector Hall, son of Earth-Two's Hawkman and Hawkgirl, who possessed the ingenuity of Beautia herself... as both inherited such mental might from their scientific sires. Though not carrying on traditional costumed identities, Beautia was dressed regally while the empresses of Venus, much as Lyta was princess of Paradise Island and was arrayed in aspects of Amazonian armor. And Magnificus did dress as Captain Marvel once to help free a captured Billy Batson. They were two former villlains turned heroes although other contemporaries of theirs remained wicked as members of the Comfederarion of Evil who paralleled Lyta and Hector's heroic Infinity, Inc. team.
A third parallel player in this teen tale of tragedy and triumph was Nuklon aka Albert Rothstein, a genetic mutant further irradiated to grant him superhuman strength and durability as well as the ability to phase his body through objects and cause it to grow gigantic. This was somewhat mirror by the abilities of Ibac aka Stanley Printwhistle, who possessed superstrength and a gigantic body that allowed him to aid the Sivanas' repeatedly in their battles versus the Marvel Family. Additionally, Ibac had a brief alliance with the flame emitting Sabbac aka Timothy Karnes and the shadow casting Dora Keane aka Darklimg, all powered by the same source and members of a Confederation. As the counterparts to Jade and Obsidian, these assembled villains were the Earth-S dopplegangers of Earth-Two's Infinity, Inc, which operated at the same time as the Confederation of Evil which Ibac, Sabbac, Darkling and others who were members for a brief period of time. Another ally of the Confederstion was the winged Crateis, counterpart to the winged Northwind.
