Nelly is a female fourth-grade student at South Park Elementary. Nelly has long brown hair and parts it into two pigtails. She wears a light green sweater with a picture of a daisy on it and wears dark green pants. Throughout her appearances, she seems very confident and headstrong. According to Bebe Stevens, Nelly would never let the boys see the list, so it can be assumed she is trustworthy, at least to the other girls. She also seems to be one of their leaders during the Gender War, pitting her directly against the W****** Out movement. Judging from Butters's injuries, Nelly is able to fight, and she noticeably does not flinch when he tries to attack her. Her ability to fight and her loyalty to the List-Making Committee may be the reason she is the keeper of the lists. When Cartman is trying to get the girls to say something funny, she speaks back to him sarcastically.
