Superman, back in time! In the past on his home planet Krypton, Superman is left to uncover some uncomfortable truths relating to the Phantom Zone and his own family – or, more specifically, his father, Jor-El! But what will those truths mean for him in the present day? And just how many unexpected allies and enemies can he unearth along the way?
After a harrowing journey to a war-fueled planet, things are going pretty well for Superman: the upper limits of his supercharged powers have yet to be reached, and the futuristic transformation of Metropolis has begun. But Lex Luthor has found the perfect instrument with which to undo everything Superman is working to achieve: longtime foe Metallo, whose hatred of Superman is matched only by his hatred for Luthor himself.
As Metallo continues to evolve, a new enemy rises: the nightmarish threat of the Necrohive!
