Bio: Volcana, was once called Claire Selton. As a teenager,
Claire showed an aptitude for pyrokenesis -- the ability to start fires
with one's mind. Her parents sent her to Metropolis's Center for
Paranormal Studies so that she could learn to control and develop her
power, but she was soon spirited away by government agents who had big
plans for her. According to the director of the Center, the agents
"stripped away her past, code-named her Volcana, and tried their hardest
to turn her into a living weapon."
But Volcana wouldn't go along with the plan. She escaped from the
agents, became a hunted fugitive and survived the only way she could: by
stealing. Eventually captured by Superman, he put her on an abandoned
island, where he would periodically deliver food to her, as long as she
stayed on the island didn't harm anyone.
