Circe spent some time in the Pit of Eternal Torment with Medusa, in whom she confided her hatred for Hippolyta. She was given an early parole, should she promise to leave Hippolyta alone. When Circe was breaking into the Natural History Museum, she was intercepted by Batman and Wonder Woman. Circe took this opportunity to get back at the Amazon Queen, by getting to her daughter, so she transformed Diana into a pig.
Circe always had the ambition to become a renowned singer, which hailed from jealousy of her cousins, the Sirens. So, she went to perform at the Amphitheater in Greece. There, she was confronted by Batman and Zatanna, but her superior powers could easily outmatch them. When Batman proposed a deal for her to lift the spell from Wonder Woman, Circe asked for his dignity, so he would have to sing for an audience. Circe was moved by Batman's performance and lived up to her part of the deal, and restored Wonder Woman.
