Monarch

Few characters arrive with the kind of immediate, electric impact that Monarch did — debuting in Hawk and Dove #24 in 1991, right at the threshold of the Copper and Modern Ages, when DC was pushing its storytelling into bold, consequential territory. Created by Barbara Kesel, Karl Kesel, and Greg Guler, this is a character whose very first appearance carries the weight of a pivotal moment, sharing pages with heavyweights like Power Girl, Hawkman, Wonder Woman, and Bruce Wayne. Though their catalog footprint is compact — spanning Hawk and Dove, Hawk and Dove Annual, and Hawkworld Annual — Monarch's debut-issue status makes them a genuine collector's touchstone from an era when DC wasn't afraid to shake things up.
