 Wendy made her first appearance unnamed, but clearly recognizable, in "The Spirit of Christmas".Wendy has a very strong dislike for Cartman, as he has cursed her out multiple times for her feminist beliefs, and regularly belittles her when she tries to speak in class.In "Breast Cancer Show Ever", she defends her beliefs and reputation by fighting Cartman, which Cartman tries very hard to avoid because he is afraid that the other male students will make fun of him for being beaten up by a girl.
