Heatstroke

Bursting onto the scene in The Flash #1 (2010), Heatstroke is a Modern Age DC creation from the red-hot creative team of Geoff Johns and Francis Manapul — a debut that couldn't have a more prestigious pedigree. With only a handful of catalog appearances, this is a rare, niche figure in the Flash's rogues-adjacent world, sharing pages with heavy hitters like Captain Cold, Mirror Master, and the Scarlet Speedster himself, Barry Allen. For collectors who love digging into the deeper corners of DC's modern era, Heatstroke is exactly the kind of discovery that makes the hunt worthwhile.
