Superboy #63

In "Hyper-Tension! Part Four: For Every World— A Doomsday!", Superboy faces his darkest hour as the Challengers of the Unknown crash into Black Zero’s fortress, revealing a chilling truth: Westfield was destroyed when her own Superboy sacrificed himself to power the hyper-jacket. With the Doomsday Chamber sealed and the original Challengers trapped inside, Superboy’s doppelgänger opens the door—only for Knockout to push the heroes out and lock it behind them. With her world gone and no one left to save, she prepares to fight Black Zero alone. Written by Karl Kesel and illustrated by Tom Grummett, with inks by Kesel and colors by Buzz Setzer, this pivotal issue features a cover by Tom Grummett and Karl Kesel.
