Aside from being the "fat kid" in the cast, Eric Theodore Cartman is often described as being abusive, anti-Semitic, violent, campy, aggressive, greedy, corrupt, sexist, bigoted, self-centered, rude, racist, and extremely manipulative. As other people make fun of his weight, he goes on to insult the others, and often acts in a manner that opposes to others. This causes the other boys to dislike him, although there are times when he has shown ability in business and leadership.
