Lisa Simpson

Intro Intelligent, kind and passionate about the planet and all living things, Lisa Simpson, at seven years old for the first 3 seasons of the Simpsons and eight years old from season 3 episode 1 onwards , she is the second child of Homer and Marge, the younger sister of Bart, and the older sister of Maggie. Lisa's high intellect and left-wing political stance creates a barrier between her and other children her age; therefore she is considered a bit of a loner and social outcast.
