Ah Faora Hu-ul and Badra, survivors of extinguished worlds, leaving devastation in their wake. Faora was the self-professed master of the Kryptonian martial art known as Horu-Kanu while Badra was the greatest strategist of her native planet. Faora ended up exiled to the Phantom Zone after her crimes against mankind... yes only MANkind which she resoundingly despised... shortly before Krypton exploded. Badra was the princess of her planet Hator's supreme power, and when war broke out she was concealed in a lead mine that shielded her and her along from a cosmic bomb that destroyed her world.
Eventually Faora found the means to escape the Zone by enlisted the aid of a human on Earth-One whom she had connected to telepathically, who located an alien artifact in the possession of Clark Kent that freed Hu-ul. As for Badra, the mine she was located within when Hator exploded closed in around her and became a meteor that eventually landed on Earth-Two. Upon their arrival, these femme fatales came in conflict with Superman and Wonder Woman, respectively, each with powers rivaling this powerful pair. And yet, both were outsmarted by their more seasoned opponents. Faora returned to the Phantom Zone to share her imprisonment with her fellow wayward Kryptonians while Badra was taken to the Amazon's Reformation Island to condition her into becoming a model citizen. Both became background players among the Zoners and Amazons, after that.
