Bizarro Superman was a semi-retarded, imperfect clone of Superman created by Lex Luthor in an attempt to impress Superman into becoming Lex's friend. It failed for many reasons. One, Bizarro didn't have a weakness from Kryptonite, so Lex couldn't control him. Two is that Lex was bald and bald people get beat up by Superman, ie Brainiac. And three, the clone was imperfect so it didn't impress Superman, at all. So Bizarro flew away with a Bizarro Lois Lane and created his own imperfect planet known as Bizarro Earth. And it had Bizarro Buildings and Bizarro Bridges and Bizarro Clones of the two original Bizarros, who in turn were Bizarro clones of Superman and Lois Lane. So in actuallity, the Bizarro clones of the original Bizarros should look like Lois Lane and Superman, but they don't because for some reason the Bizarro clones of the Bizarros were perfect in the sense that they were exact replicas of the first two Bizarros, even though they used the same machine that Lex did to create imperfect clones. So it all points back to that guy from the fifth dimension with a lot of letters at the end of his name. Then the original Bizarro falls into a disentegrator and reforms into a blue zombie-alien thing. Got that? Then, Professor Zoom tried to eat him under the belief that it was quicksilver and would make him faster, but he killed himself.
