Kimberly Ann "Kim" Possible (voiced by Christy Carlson Romano) is a high school student and freelance hero/vigilante. She is unusual in this in that she not only lacks a secret identity, but also remains on good terms with various law enforcement, government, and military agencies. For the most part, her classmates are aware of her work but do not comment on it unless it affects them directly. At school, she is cast as one of the "popular kids," head of her cheerleading squad at school, and a straight-A student, rather than as a misunderstood outsider/underdog as typical of the genre.
