On a Superhero/Villain kick anticipating "The Avengers", but in fairness decided to do a DC villain this time- Cheetah: Deborah 'Debbie' Domaine was introduced as the niece of Priscilla Rich. A beautiful young debutante, Debbie feels remorse for her wealthy upbringing and decides to become an ecology activist, meeting Wonder Woman and striking up a friendship with her. Later that same day, Debbie is summoned to her Aunt Priscilla's mansion and finds her there, succumbing to illness. After Priscilla Rich dies, Kobra's operatives capture Deborah and bring her and the Cheetah costume to Kobra's headquarters, where he questions her: "You didn't know about your aunt's secret life, did you? Well, you'll learn—Since we couldn't have the original, we decided to make do with a recreation. You shall be that recreation, Ms. Domaine." Kobra tortures and brainwashes Debbie and provides her with an updated version of the Cheetah costume. The original suit included a cat-eared cowl and clawed, flat-soled boots. Debbi's version has a V-neck, slit to the sternum, a headband with cat-ears (concealed for the most part beneath her long, auburn hair), and heeled boots. Both costumes include razor-sharp chrome steel nails, painted bright red. "You are my servant, and I, your master. You are the Cheetah!" he cries, "And you will fill the world with terror!" Debbi has several conflicts with Wonder Woman and also serves as a member of the Secret Society of Super Villains in a conflict with both the Justice League of America and the Justice Society of America.
