Lisa Simpson

Lisa Marie Simpson is a charismatic 8-year-old girl, who exceeds the standard achievement level of children her age. Not to everyone's surprise, she's also the moral center of her family. In her upbringing, Lisa lacks parental involvement of Homer and Marge, which leads to hobbies like playing saxophone and guitar, riding and caring for horses, and interest in advanced studies. In school, Lisa's popularity's affected by those who view her as a geeky overachiever, which leaves her with only a few friends. Lisa Simpson's a smart, witty, independent girl who focuses on her goals and strives to reach her potential, and at age 8 she's already a member of MENSA with an IQ of 159.
