| abstract | - Black Zero was a space saboteur who destroyed planets. He had been hired to destroy Krypton, and discovered that the internal stresses which would have destroyed it in any case were dying down, necessitating his involvement to ensure it exploded. In the present day, Black Zero came to Earth, threatening to destroy it as he did Krypton. In desperation, Superman released Jax-Ur, a prisoner of the Phantom Zone, who wished to avenge Krypton's destruction. As he launched a devastatingly powerful missile toward Earth, Black Zero attacked Jax-Ur with a red Kryptonite bullet, causing his body to mutate wildly into several serpent-like forms. This proved to be Black Zero's undoing; While Superman saved the Earth from the missile, Jax-Ur transformed into a Medusa-like form, turning Black Zero to stone with his gaze. Black Zero's body was then shattered by Jax-Ur, in recompense for what he had done to Krypton. Black_zero_LRJ.png|Black Zero 0.9 by L.R Johansson
