Heatstroke had the power to project bursts of flame, and was a member of the Masters of Disaster, a group of mercenaries who specialized in causing natural disasters. This made her an enemy to the Outsiders. She was in a romantic relationship with her teammate Coldsnap, but they could never be together because of their opposing powers.
Note:Heastroke's history continued mostly unchanged after Crisis up to the time of Rebirth, when a new version appeared.
