Nelson Muntz(voiced by Nancy Cartwright) in "The Simpsons"
Catchphrase: "Ha ha!"
Weapons of choice: Anything lying around.
Why he's here: Because "The Simpsons" is a dog-eat-dog world and Nelson is Bart's alpha. (And Milhouse's. And Martin's. Not Lisa's, though.)
Bully rating: One fist. He's redeemable. Maybe.
