He's cut a swath through the Justice League and laid waste to Metropolis. He's Doomsday, and he has only one thing on his mind--killing the Man of Steel... permanently! The JLA desperately needs Superman's help, but he's busy on a mission of mercy: trying to save the life of the critically ill child of Lana Lang and Pete Ross. Can Superman turn his back on his two oldest friends in their time of need? Can the JLA stand against Doomsday on its own?
