Who has more fun than the witty antagonist with a vendetta? So my answer is overwhelmingly ANTAGONIST. I could hijack a bus with a helicopter full of endangered penguins destined for a field trip to Machu Picchu while attempting to steal the Ark of the Covenant from an exotic antiquities dealer trying to sell it to some army of somewhere, and also capture the soul syrup that seeps from the ark. Who wouldn't wanna do that?
