9. Cyborg Superman

I gotta say, I love a good visual design. If you make a character look really cool, you can get away with a lot.

When Cyborg Superman debuted, he was one of four replacements for the recently deceased real Superman. And the comic he was in tried to convince us that A: He wasn't evil; and B: He was the real Superman. This is a pretty solid definition of rolling a boulder uphill.

I'm sorry, but you're not going to convince me that Clark the T-800 over there was the real Superman. Not gonna happen. You'd have an easier time convincing me that Dr. Doom was a pediatrician. But it turned out that the "˜borg was actually Hank Henshaw, a one-off character from a previous Superman comic that satirized the Fantastic Four's origin.

Since then, Cyborg Supes has been as much a Green Lantern villain as a Superman villain, mostly since the guy annihilated Hal Jordan's home, Coast City. That's a fair reason to hate a guy.
