Eric Cartman

Eric Theodore Cartman, commonly known simply as Cartman, is a prominent character alongside Stan Marsh, Kyle Broflovski, and Kenny McCormick. Cartman often plays the role of the main antagonist in certain episodes, such as Trapper Keeper. The other three main children don't really consider Cartman a true friend and can't quite remember why they started hanging out with him, but an uneasy form of friendship eventually develops between them.
