Bio: An imperfect duplicate of Superman created by Lex Luthor.
Using a stolen strand of Superman's DNA, Luthor developed his own
"Superman", a prototype for a line of super-guardians available to the
general public. By dialing 555-LEXX, a person in trouble could have one
of Luthor's guardians rescue fly to their aid anytime of the day or
night - for a price. Unfortunately for Lex, it didn't work.
The cloning process was unstable and the Superman clone mutated in form
and mind into a grotesque parody of the Man of Steel dubbed a "Bizzaro"
by a horrified Metropolis. Possessing bits of the original Superman's
memory, Bizzaro set about imitating Superman's heroic actions with
disastrous results. Trying to save an old woman from being struck by a
bus, Bizarro did not quickly fly the woman to safety as Superman would
have done, but punched the bus, sending it and its thirty-odd passengers
crashing into the river!
Several more fiascoes of this sort led Bizarro into a showdown with the
real Superman. Superman won the battle and placated Bizarro by giving
him complete jurisdiction of the moon. Now Bizarro patrols the moon much

Superman. The fact that he has a crush on Lois Lane doesn't help any,
