5. Egghead
Every Batman villain has a gimmick. And they don't come more gimmicky than Egghead, egg-cellently brought to life by veteran horror star Vincent Price. The self-proclaimed smartest criminal in the world, Egghead is thoroughly obsessed with eggs his crimes are all egg-related, he puns at an egg-stremely painful rate and he even looks like an egg. As is clear, Egghead isn't the most well-rounded character in the Batman universe but is made a fantastic villain thanks to Price who hams it up egg-spertly. Sorry, I think I've stretched this yolk too far
