4. J. Wilbur Wolfingham

You know, Superman is one of the hardest characters to come up with villains for. They either have to be hyper intelligent or the strongest creature in the Andromeda Galaxy. So of course, who is Superman's greatest foe? Why, that'd be J. Wilbur Wolfingham, who is a middle-aged con man. Logically.

Wolfingham constantly appears with new schemes and flim-flams. New shenanigans and hijinks. But every time, Superman takes time out of his day to foil these attempts at con artistry. Maybe not the best use of your time, Supes. I mean, I'd personally suggest leaving the middle-aged swindler to like, The Guardian, maybe. Or Red Bee. You know, someone more his speed. You have world ending crises to stop; taking time out of your day to prevent a failed con artist from failing even harder seems misguided.

The best thing about Wolfingham though? According to his Who's Who entry, "No one seems to know what the "˜J' stands for."

Perfection.
