Hypnota uses this new talent both in her stage act and in crime, including the selling of her mesmerized victims to slave merchants from the planet Saturn. Hypnota hypnotizes her twin sister, Serva, into becoming her assistant on stage and in crime. When Saturn's slave trade in Earthlings is banned as part of a peace treaty with Earth, Hypnota, hoping to revitalize her source of revenue, steals America's contingency defense plans against the ringed world in order to foment hostility and break the treaty. Her warmongering efforts attract the attention of Wonder Woman. Hypnota battles Wonder Woman with the unwilling aid of Hypnota's twin sister Serva. Hypnota hypnotizes Wonder Woman a number of times, making her publicly humiliate herself and help her in her crimes and warmongering. Finally Wonder Woman breaks free of Hypnota's control and frees Serva from hypnosis, stopping Hypnota with the aid of a mirror that causes Hypnota to hypnotize herself.
