The past of Zara was that she was an Arab girl and wore belly dancer attire. According to her tales, she was sold into slavery as a child; which created in her an intense hatred of men. Using a flair for pyrotechnics, she eventually created a new religion (The Cult of The Crimson Flame), which had swept the globe. Zara rigged various fire-based effects to dazzle her followers and keep them in thrall to her. After her initial defeat by Wonder Woman, the Cult went underground; and Zara was able to scare up at least one follower to do her bidding when she joined Villainy Inc.
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. Dr. William Moulton Marston assigned the color crimson to represent the inducement emotion that Zara was activating when trying to influence people.
