A quiet, brooding member of Jack's chorus. He is at first little more than a mystery, a quiet, intense boy who seems to hide himself from the other boys. But as the trappings of civilization begin to recede on the island, he begins to reveal himself, first by throwing rocks at littleuns (and purposely missing), then by killing a pig more viciously than necessary.

The smartest boy on the island. Due to his obesity and asthma, He is also the weakest of the biguns. He believes passionately in civilization, law, and reasoning through problems, but he seldom does any work because of his obesity and his nonstop craving for food. He also has a tendency to lecture and criticize. His condescension infuriates the other boys and inspires them to single him out, ridicule him.

The head boy of his chorus back in civilization, he becomes the leader of the hunters on the island. He loves power. Laws and rules interest him only because they give him the chance to punish the other boys and express his dominance over them. He loves to hunt and kill because it gives him a chance to dominate nature. He gets angry whenever he doesn't get his way: he believes a proper leader issues orders and is obeyed.

The largest and most physically powerful boy on the island. Despite his size and strength, he shows no signs of wanting to dominate others and is preoccupied with being rescued. He insists on planning and following the rules, and is able to prioritize the needs of the group above his own selfish desires. He feels the exhilaration of hunting and killing, but he always manages to suppress savage feelings.

A dreamy, dark haired boy, prone to fainting spells and occasional fits. He is the only member of Jack's chorus who doesn't become a hunter. The most generous of the biguns, he helps Ralph build the shelters not out of a sense of duty, but because he wants to. He is also the most insightful and in many ways the bravest of the boys. Only he recognizes that the boys carry the beast within themselves.

The identical twins Sam and Eric who do everything together. They so closely resemble each other that the other boys use just one name to refer to both of them. The twins prove to be less influenced by fear of the beast or Jack than any of the other boys (except Ralph and Piggy), perhaps because as twins they're less alone than any of the other boys.
