If choosing from the 'list,' then I'm going to go with "Napoleon the Pig." Driving the horse to death while living it up...too many real world exemplars for me. And Voldemort is spooky, but it's in Harry Potterworld, and so I just don't get as hooked. I've seen Saruman, and the reality drives away fear.
The maia that one fears is worse than the wizard one cheers.
