It’s the return of the Supermen! In the aftermath of the "Sacrifice" and "The Insiders" story arcs, Superman and Superboy find their way to the ruins of the old Fortress of Solitude in the Arctic with John Henry Irons to check on the missing Eradicator. Unfortunately, the Eradicator still believes Krypton’s sons are rogues, and he’s prepared to take care of that problem!
