Criminal mastermind Lex Luthor once acquired the designs for a Duplicator Ray first envisioned by a scientist named Professor Dalton. Modifying the device, Luthor intended on using it to create a super-strong clone of his nemesis, Superman; a mindless slave who would obey Luthor's every command. However, the duplication process failed, and resulted in the creation of an imperfect duplicate of Superman. This artificial being, later began to refer to itself as Bizarro.
