Marwin Meathead is fat, sadistic, greedy, lazy and self-important; he possesses all the bad qualities one can possibly find in a thinking human being. Always wearing his helmet and carrying a weapon, a wooden club with a huge nail right through it. It is revealed to be made of the core wood of an Arch-oak. He is unstoppable in plotting against his two buddies - Oldhead and Shorthead. Despite his sadism, brute nature and professed lack of any kind of intelligence, he's shown to be quite intelligent when it comes to certain subjects, as well as being shown at times to be extremely cunning when it comes to finding ways to make money, often taking advantage of the trusting nature of others.
