Bizzaro

Yes.

Originally he was like Superman's exact opposite. This was taken to extreme lengths eventually resulting in a Bizzaro Earth (it was shaped like a cube) which had a bizzaro lois. There the Bizzaro's committed crimes and atrocities against each other because from their backwards point of view they considered it good. They would say good-bye when they meant hello, and hello when they meant good-bye, and they would read the end of a book first.

In the Modern comics Bizzaro is basically just a mentally deficient version of Superman. He tries to do well, and to his credit occasionally does the right thing, but usually just causes more trouble that he helps, he can be easily confused, and is often tricked into thinking that Superman has gone bad and must be stopped. This is the Bizzaro that was used in S:TAS.

In Smallville Bizzaro is and alien (not from the kryptonian race) phantom from the phantom zone, that came into contact with Clark and stole a small piece of his (clarks) DNA so that he could make himself an exact duplicate body of Clarks. But he grows weaker in sunlight (although it doesn't appear to be all that substantial, it just seems that Clark has the upperhand when in sunlight, and its when Bizzaro is exposed to the sun that his face goes white and cracks like the traditional 'Bizzaro look') and Kryptonite makes him stronger. Bizzaro also has all of Clarks memories as well as his own (from when he was a mere phantom from 'the zone'). Smallville's Bizzaro is also not stupid, but in fact very intelligent, he is however (obviously) evil.

Also he wears darker shades of Blue and Red, with a blue Jacket on top and a red shirt underneath, whereas Clark Wheres a bright red Jacket with a blue shirt underneath.

Nobody's a insensitive bogot for not liking a retarded character.
