She is the daughter of Homer and Marge Simpson; Sister of Bart and Maggie.

The brightest kid in town (although this would be disputed by Martin Prince). Her hobbies include playing the saxophone.

Lisa is both a vegetarian and a Buddhist. She is seen by some to whine at times or to have persistent sense of superiority that often grows into self-aggrandizement, and is often quite gullible despite her intelligence.
