In hopes of having a Superman of his very own, Lex Luthor called upon his top scientist to scan and replicate the hero's genetic structure. Due to complications in the construction of the carbon copy, the results gave birth to the monstrous menace, Bizarro.
As the mirror image of Superman, Bizzaro is his imperfect duplicate, as his his poorly constructed genetics caused him to become the complete opposite of the heroic Man of Steel.
Embarking on another plan to kill Superman, Lex Luthor orders his scientific team to create a clone of Superman that he can control. However, wrongfully starting from the assumption that Superman is a human with metahuman abilities (his alien origin had not yet been publicly revealed), the process resulted in a flawed copy, which Luthor dubbed "Bizarro" and ordered it disposed. The monstrous clone survived, however and attempted to mimic Superman before being finally destroyed when colliding with Superman in mid-air.
Years later, Bizarro is recreated by the Joker when the villain steals the powers of the Mister Mxyzptlk. Creating a twisted version of Earth called "Jokerworld", the villain designates Bizarro to be the planet's greatest hero and leader of a re-imagined "JLA". When Mxyzptlk regained his powers, the imp allowed Bizarro and several other beings to remain on the restored Earth.
Superman attempts to help the "clone" adjust to the normal Earth but during the Infinite Crisis, Bizarro is tricked into joining the reformed Secret Society of Super-Villains.
