Beatriz da Costa and Carol Vance Martin were two young women, born normal, who were bequeathed elemental powers from early ages.
Beatriz adopted the alias of Green Fury, using her emerald flames which she could project from her nostrils and eyes as propulsion to fly and to create illusions, as the resident hero of Brazil on Earth-One. Eventually, she encountered the Super Friends who took her in as a provisional member. At the same time, she was the branch manager of Wayne Enterprises in Brazil. Soon thereafter, she became a member in good standing of the Global Guardians.
Carol was adopted following a tragic forest fire into the wealthy Martin family. Although she lived a life of privilege she decided to use her abilities to emit flames to fly and to create weaponry to became a superheroine in the United States of Earth-Two. Although there was never a documented case of her meeting the All-Star Squadron, which operated during the peak of her costumed career, she was a contemporary of this group and may have met them at one point or another.
