Obama and Spiderman...

Each of the Supermen were designed with ideas taken from some of the monikers that Superman is often associated with. The four new heroes were:

• The Man of Steel: John Henry Irons was an ironworker and ex-weapons designer for the military who wears a suit of armor and wields a hammer. He did not claim to actually be Superman, but rather to represent the spirit of Superman and continue his legacy. Steel appeared in Superman: The Man of Steel starting with #22. He later changed his name to just "Steel".
• The Man of Tomorrow, also called the Cyborg Superman, arrived with augmented Kryptonian technology. He was scientifically proven to be Superman, but claims amnesia in explanation to his part-mechanical nature. The Cyborg Superman appeared in Superman (vol. 2) starting with #78. He later became a major supervillain.
• The Metropolis Kid, who hated being called Superboy, is a reckless teenage clone of Superman. This Superman appeared in the Adventures of Superman starting with #501. He is the result of the brief time Cadmus attempted to clone Superman. He later had a career as Superboy.
• The Last Son of Krypton was a visored, energy-powered alien who dealt with criminals lethally. The Last Son of Krypton appeared in Action Comics starting with #687. He claims to have the memories of the original Superman, but his emotional distance makes Lois uncertain. He later was discovered to be the Eradicator, a reformed Superman enemy.[3]
