Ferro

A minor but intriguing corner of the DC Universe, Ferro made their debut in 1998's Green Lantern #98, brought to life by the celebrated creative team of Ron Marz and Darryl Banks during comics' Modern Age. Across nearly two decades of DC publishing, this character has kept remarkably distinguished company — sharing pages with icons like Green Lantern, Batman, Robin, Supergirl, and The Flash — and has turned up in retrospective and anthology fare like DC Universe: Legacies, suggesting a character woven into the broader tapestry of DC history. With only a handful of catalogued appearances, Ferro is a genuine deep-cut discovery, the kind of find that rewards curious collectors who love unearthing the quieter threads of a rich universe.
