Master Jailer is kind of redundant since there is Lock-Up.
Anyways, I came here to say Toy Man and Puzzler but they're already mentioned. Blood Sport is another good choice.
A few who hasn't been mentioned:
************ Black
-Silver Banshee
-Bruno Manheim.
Smarty Pants...all growed up!
Rose and Thorn could be a good story choice. Silver Banshee would make for an interesting situation.
