Like all true heroes, Superman tries to protect life -- all life -- even in the pitch of battle. But Superman has rarely seen a scourge like the Aliens. While a few of these creatures may not be a match for one with Superman's near limitless powers, a few hundred of them unleashed like rats in the otherwordly utopia of New Genesis DOES pose a considerable problem. What's worse, these aren't just any Aliens, but the scions of Darkseid's Parademons, used as willing hosts for their master's devious machinations. But even THIS is not the ultimate horror. Darkseid has his sights set on a certain brooding inhabitant of New Genesis...and has saved the most insidious role for him!
