Which comics supervillain really deserves a shot on the big screen?

Not only do we keep getting the same few superheroes starring in movies over and over — but they always face the same villains. Superman fights Luthor and Zod. Batman meets the Joker and Catwoman. But which supervillain would you like to see in a big movie?

As usual, please include a picture of your choice, so we can scroll through the rogues gallery of great villains and marvel at the depth of talent that's been benched on the big screen. Thanks!
