Joe Agate is the main antagonist of the 2006 special, He's a Bully, Charlie Brown, the last Peanuts special to have Bill Melendez involved. He is the son of the owner of the trading post at the summer camp. He is a bully, like it says in the title, who plays beginners and deceives littler children by telling them he is only teaching them. But after he is done, he has tricked them into giving up all their marbles. Particularly, he tricks Rerun Van Pelt, the brother of Lucy Van Pelt and Linus Van Pelt, whose paternal grandfather, Felix, was once a marble's champion in 1939.
