Bizzaro is the result of an attempt to clone Superman for the Rebellion's cause. The reason for his deformed look is due to an incompatibility between Human cloning technology and Kryptonian DNA. The fact that he has the powers of Superman is the only similarity between the two. Bizzaro has the mind of a child and is viewed by his creator Dr. David Connor as his only son. Bizzaro's life was short lived due to an unexpected imbalance in his chemical makeup. One day during an attempt to save Dr. Connor from a Justice Lord raid on the lab they were living in. Specter was able to destroy Bizzaro with his an energy blast. With this blast Bizzaro's molecules flew apart. In the following confusion Dr Connor was able to escape, but blamed himself for the death of Bizzaro and is working to create a new one on his own time. It should also be noted he wanted his own version of the outfit Superman wore when he was good. In his mind the only version that would work was one that was darker and reversed.
