Moe is a very large, stupid, and ugly bully who is supposedly six years old like Calvin but shaves and is large enough to be a high school freshman. He calls his victims "Twinky" and threatens to "pound" or "cream" them to get lunch money from them. He is very easily confused by words that aren't monosyllabic. Calvin once theorized that Moe had a bad home life or other personal problems that made him take out his insecurities by bullying, and promptly got beaten up.
