The Negative Superboy

The Negative Superboy

After Superboy destroys a massive energy monster in deep space, an evil, dark-colored and negatively-charged duplicate is created. Upon returning to Smallville, Superboy is dismayed that everyone, his foster parents the Kents included, seem to embrace the Negative Superboy as his apparent "replacement". Later, he realizes that the evil "twin" has told how the world will be destroyed unless he leaves Earth, so the Boy of Steel bides his time until he can coax the negative clone far away from the planet and eliminate him permanently (SB No. 168/2, Sep 1970: "The Negative Boy of Steel!").
