Bart shares a sibling rivalry with his younger sister, Lisa, but has a buddy-like relationship with his youngest sister Maggie, due to her infant state. While Bart has often hurt Lisa, and even fought her physically, the two are often very close. Bart cares for Lisa deeply and has always apologized for going too far. He also believes Lisa to be his superior when it comes to solving problems and frequently goes to her for advice. Bart is also highly protective of Lisa: When a bully destroys her box of cupcakes in "Bart the General", (season one, 1990), Bart immediately stands up for her.
