At one point, the Amazon Queen Hippolyta took over the role of Wonder Woman and traveled back in time to aid the JSA against the Nazis. During this time, Helena began to look to Hippolyta as a mother figure and believed that she was indeed the daughter of the Amazon queen, despite the knowledge that her true parents were killed during the war. When Queen Hippolyta returned to her own time, Helena sought a magical means to gain eternal youth; this was accomplished via a magical document that, if destroyed, would revert Helena to her true age and possible death. After this was done, Helena met Hippolyta's true daughter Diana and took an immediate dislike to her. By this point, Helena's mental state was near collapse, as she began to behave irrationally. Diana took her to Themyscira, where Hippolyta addressed Helena as a daughter to support her fragile psyche. After Hippolyta's death during the "Our Worlds At War" saga, Helena went into mourning and much of her mental imbalance was resolved. Thereafter she served Artemis and Philippus as a trusted aide. Her powers were briefly stolen from her by Barbara Ann Minerva whose role as the Cheetah had been usurped by Sebastian Ballestros. Minerva used the power of Tisiphone to kill Ballestros, regaining her Cheetah form, and restored Helena's powers.
