Egghead was played by Vincent Price. An awesome actor. Egghead however was not as awesome in the Batman emeritus campaign. However he did have the best line ever that rivals all ‘The Riddlers” riddles….”
“What do you call…an egg…that blows up”…..
“An Egg-splosion..muhahahahaha” and then he’d throw an egg bomb or something.
He went insane after being foiled so many times and died in Arkym Asylum.
