The Secret Society of Super-Villains
A wealthy young debutante who felt guilty about her wealth and attempted to make amends by joining ecological extremist groups such as the Organization for Ecological Sanity, Debbi Domaine found herself summoned to the deathbed of her eccentric and reclusive aunt, Priscilla Rich. But before the dying old woman could reveal her darkest secret to Debbi, Priscilla Rich breathed her last.
Recoiling from the sight of the dead woman, Debbi staggered back against a closet and was knocked unconscious by a mannequin that fell from within, a mannequin clad in a bizarre cat-like costume. In the last instants before darkness overcame her, Debbi saw a weird figure in a reptilian costume enter the room.
Debbi awakened to find herself a prisoner in the hidden headquarters of the would-be conqueror known as Kobra, hanging spread-eagled from the ceiling of a room filled only with sophisticated projectors. Kobra explained that he had originally come to enlist Priscilla Rich, who had secretly been the super-villainess called the Cheetah, into his employ, but since the older woman was now dead, Kobra would have to make do with a re-creation.
Despite Debbi's protests, Kobra filled the room with holographic images, hundreds of scenes, each worse that the one before: factories polluting air and water, tankers spilling oil, hunters murdering helpless seals. These scenes were calculated to fill Debbi with fury, and this, combined with her sense of helplessness and a series of electrical shocks, drove the young woman hopelessly insane.
Released from her restraints, Debbi was given a costume similar to that of her aunt, and told by Kobra that she was now the avenger of wronged nature, the savior of oppressed animal-kind -- the Cheetah!
At Kobra's command, the new, improved Cheetah battled Wonder Woman, but when the Amazon Princess at last defeated Kobra, the Cheetah was left to her own devices, finally joining the Secret Society of Super-Villains, an evil organization now led by the Ultra-Humanite. At this writing, the Cheetah is incarcerated at the Arkham Asylum for the Criminally Insane.
