Superman's brilliant, brutal archnemesis Brainiac has forged an unholy alliance with one of the Man of Steel's greatest foes, and together they have set their sights on New Krypton -- and the tens of thousands of Kryptonian's who live there. Even as their technological terror rains from the skies, internal turmoil threatens to tear their target apart from within.
But the fate of more than just New Krypton is at stake. Brainiac holds the people of countless worlds hostages on his ship. If they are not freed --- if Superman fails -- the future will cease to exist.
Meanwhile, the ruthless General Zod will stop at nothing in his quest for vengeance against those who dare defy New Krypton -- and once he's through with Brainiac, the planet Earth is next on his hit list.
Now Superman and a small band of his closest friends -- Supergirl, Superboy, Mon-El, and the Legion of Super-Heroes -- must fight to save their planets, their people, and their very lives. Will they stand together or fall forever?
