Non-Disney Heroes Vs Villains
Long ago, there was a woman named Mrs. Mangetsu, she and her husband Professor Mangetsu gave birth to a baby girl named Miyoko. She cared for her very much, playing with her and combing her hair. But one day, Miyoko fell horribly ill, and none of the doctors could find a cure for her. Devastated by this report, and driven to insanity by it in front of her husband, she decided to use dark magic by giving her soul to the The Demon King in exchange for saving her daughter. The exchange worked, despite her husband’s attempts to stop the ceremony and Miyoko was cured of her illness. It was also with the deal that she transformed into a terrifying gorgon.
