Heatstroke

Heatstroke is a DC supervillain with heat-based powers who debuted opposing Batman and the Outsiders. She is one half of the criminal duo Coldsnap & Heatstroke, capable of generating intense thermal energy, and has clashed with numerous DC heroes over the years.

Bursting onto the scene in 1985's Batman and the Outsiders Annual #2, Heatstroke is a Bronze Age DC creation from the pen of Mike W. Barr and artist David Ross — a duo who knew how to craft characters with real edge. Over a publishing span that stretches nearly three decades, this figure has crossed paths with some of DC's heaviest hitters: Batman, Green Lantern, The Flash, Supergirl, and even The Spectre. Though appearances in the catalog are select rather than sprawling, Heatstroke's longevity across titles like DC Universe: Legacies speaks to a character with genuine staying power in the broader tapestry of the DC Universe — the kind of deep-cut discovery that makes digging through back issues so rewarding.
