Synopsis:
When Superboy prepares to stop the Mechanical Mob from stealing an armored car he discovers that his own uniform has been replaced by one with an unknown design. After apprehending the crooks, he heads for home in his Clark Kent clothes, but is sidetracked by a compulsion that leads him to a different house. Inside he finds that the Quentins believe he is their own son Kirk.

Superboy is unable to solve the puzzle, so he visits the Kent house and discovers another boy inside. The Kents claim this other boy is their own son, the real Superboy. Despite his best efforts the Boy of Steel cannot convince them of the truth or even that he has super powers.

Superboy then investigate the attic at the Kent house where he is attacked by Jor-El and Lara, who claim to have come from Krypton, which was never destroyed. He then follows Krypto on a trip through time in which his strange costume is shredded.

When Superboy returns to the present, the Quentins tell him the truth. They are really from Trombus, an alien planet with a red sun. Their son is really Hyperboy, the hero of that world, though the entire family has super powers. The Quentins came to Earth to test a hypnotic device and their indestructible costumes. They were able to hypnotize Superboy and the Kents and used androids and illusions to trick the Boy of Steel. With Superboy's help the Hyper-Family is better prepared to become heroes on their world. After a brief visit, Superboy returns to Earth with a story for his parents.
