The lovely red-haired high priestess of the mystic Cult of the Crimson Flame, a "new religion" that has begun "sweeping the world". Its symbol is an eerie "crimson flame" that appears out of nowhere at the behest of the high priestess, hanging suspended in midair and inscribing mysterious flaming messages to cow the members of the cult - the so-called "flame slaves" - into abject obedience.
I am the crimson flame of life," intones a grim voice from within the flame,"- I burn within the breasts of all who obey me! Whosoever opposes me shall be consumed!
Anyone daring to oppose the cult falls mysteriously ill and dies soon afterward.
When Helen Armstrong, a U.S. Senator's daughter who has been intimately involved with the flame cult, disappears mysteriously, Wonder Woman, Steve Trevor, Etta Candy, and the Holliday Girls follow her to Arabia, site of the Crystal Temple of the Crimson Flame, the "international headquarters" of Zara and her sinister "flame forces." Ultimately, Wonder Woman and her companions defeat the flame cultists, rescue Helene Armstrong from their clutches, and capture Zara.
I'm an Arab," explains Zara, "-my father sold me as a slave! Oh, how I hated heem! I swore I'd get revenge on men of power! Revenge - that ees my crimson flame!
It was to wreak vengeance on Helene's father that Zara had had her abducted.

To destroy enemies," continues Zara, "I put ideas in zair mind, zen zay make zemselves sick, poor fools!
Zara escapes from Transformation Island along with seven other villainesses and joins them in forming Villainy IncorporatedHippolyta referred to her flames as 'scientific trickery.'
