Superman was Earth's greatest hero until he sacrificed his life to stop the monster known only as Doomsday. Now the world and those who loved him must learn how to continue on without the Man of Steel. In this time of need, heroes like Supergirl, the Guardian and Gangbuster rise to the challenge and try to continue the Last Son of Kryton's legacy. But can they really fill the void left by Superman's death? SUPERMAN IS DEAD. But now, four mysterious beings appear--all with the powers and abilities of the Man of Steel! One claims he is a clone from the DNA of Superman. Another--half-man and half-machine--says he is Superman with a cyborg body. Still another, a cold redeemer of justice, states that he alone has the right to wear the "S" shield. And, finally, an armored figure who says he fights with the heart and soul of Superman. Who is the true Superman?
