Luanne Leanne Kleinschmidt (née Platter) (voiced by Brittany Murphy) is a fictional character in the animated series King of the Hill. She is the niece of Peggy Hill and Hank Hill(her father is Peggy's brother) and a cousin of Bobby Hill. She is drawn voluptuously, with anhourglass figure that she highlights with her standard outfit including a midriff-baring green tank top, red spandex cycling shorts, and white athletic shoes
Luanne is often regarded as dumb (it's true she isn't very intelligent), but very pretty and seductive. Luanne, as a character, has undergone some drastic changes as the show progressed. In the first season, she was portrayed as being of somewhat ordinary intelligence, had a husky voice that closely resembled Joseph Gribble's (Murphy also provided the voice of Joseph until season five; when Joseph hit puberty, Breckin Meyer began voicing him), and would easily stand up to people who wronged her.
However, the show has since changed her character significantly, raising the pitch of her voice and making her a naive character who is easily swayed by the ideas of others. She briefly joins a Jack Chick/Fred Phelps-inspired evangelical movement, registers as a Communist when a recruiter informs her that George W. Bush devours puppies, and is lured into a cult, which she thinks is a sorority at the time, that wants her to work on a farm, growing fruit to make jelly.
