Describe piggy, Ralph, and jack in the lord of flies!

Ralph is the athletic, charismatic protagonist of Lord of the Flies.

The strong-willed, ego maniacal Jack is the novel's primary representative of the instinct of savagery, violence, and the desire for power-in short, the antithesis of Ralph.

An overweight, intellectual, and talkative boy, Piggy is the brains behind many of Ralph's successful ideas and innovations, such as using the conch to call meetings and building shelters for the group.
