Synopsis:
Superboy battles an energy dragon in space. A collision with the creature causes an incredible explosion which temporarily knocks Superboy unconscious. When he recovers and returns to Earth, he finds that he has been replaced by a negative version of himself. His parents and the townspeople accept the new Superboy and reject the original. After suffering through the pain of being replaced, Superboy collides with his counterpart resulting in another explosion. His parents then explain that the negative Superboy was created from his body, and their rejection was only a hoax.
