Superboy #62

In "Hyper-Tension! Part Three: Divided By Zero," Superboy faces a chilling revelation as Black Zero reveals a twisted alternate reality where Superman’s death led to a clone’s rise as a tyrant—now ruling from Cadmus with an army of cloned heroes. With the Stormguards having separated the two Superboys and the fate of a world hanging in the balance, Conner-Superboy confronts a horrifying truth: Black Zero’s army is growing, and the chamber behind him is hatching dozens of Doomsdays. Written by Karl Kesel and illustrated by Tom Grummett, with cover art by Tom Grummett and Karl Kesel, this 1999 issue delivers a tense, high-stakes chapter in the Superboy saga.
