I haven't read that many Superman stories, so I'm interested in recommended reading for trades- back issues, especially those featuring Superman's enemies.
So who are your favorite Superman villains?
List as many or as few as you want.
List your favorite stories with the villains (if you want.)
Rank the list if you want to.
The villains, and stories can be as obscure, or well-known as you like.
I would love to hear about great stories with villains I'm familiar with, but have limited exposure like Braniac (who I really only know from the animated series, and DK2), and General Zod (Superman 2 & the latest Jim Lee issues.) I'd especially enjoy reading stories with great villains I've never heard of.
