Steel (Henry Hank Heywood III)

When teenager Hank Heywood III was gravely injured, his grandfather — the original Commander Steel — saved his life by surgically grafting a titanium-steel alloy skeleton with motorized joints onto his body, transforming him into Steel and recruiting him into the Justice League Detroit.

Forged in the Bronze Age heat of Justice League of America #242 (1985) by Gerry Conway and George Tuska, Steel arrived at one of DC's most turbulent and exciting moments, stepping onto pages alongside titans like Green Lantern, J'Onn J'Onzz, and Vibe. With key issues among their appearances and a presence stretching across four decades — from Legends to DC Universe: Legacies — this is a character whose footprint in DC history runs deeper than their appearance count might suggest. For collectors tracing the rich, complicated tapestry of the Justice League's Bronze Age evolution, Steel is exactly the kind of figure worth seeking out.
