Similar to the story of Wonder Woman, Super-Woman is an Amazon warrior and has the powers and abilities of an Amazon. But unlike Princess Diana who was a recognised leader of the Amazons, she was a renegade who left Paradise Island of her own accord after finding out about the outside world. The Amazons of Earth-Three never tried to recall her back from the outside world despite all the intervening years Super-Woman was active. She was however stripped of her immortality by the Amazons for breaking their rules. Adopting the name Super-Woman, she decided to use her powers for evil, and it would be during her criminal escapades that she encountered four other super-powered beings who would all loosely gather together in various schemes to dominate their world and become the Crime Syndicate of America.
