Firestorm

Debuting in Captain Atom #2 in 1987 under the hands of Cary Bates and Pat Broderick, this Firestorm is a Copper Age creation who stepped into the DC Universe already rubbing shoulders with some of its most iconic figures — sharing pages with Superman, Wonder Woman, Green Lantern, and the civilian faces of Clark Kent and Bruce Wayne. Spread across nearly three decades of DC publishing and appearing in titles like 52 and Adventures of Superman, this character occupies a modest but genuine corner of the DC tapestry, with at least one collector-recognized key issue to their name. A character worth a closer look for any fan who loves tracing the quieter threads woven through DC's rich modern era.
