8-Ball is a pool ball-the black 8 to be exact. Unlike the other balls, he moves by rolling around. 8-Ball will not let people forget that he doesn't have a favorite number. Despite his uninterested tone of voice, he inspired his team to overthrow Golf Ball as its leader. Everyone seems to listen to him whenever he opposes Golf Ball's directions. In fact, Basketball is 8-Ball's closest follower, asking him for guidance during BFB's most tumultuous time.
