In Lord of the Flies, Piggy fears Jack because Jack intimidates him and he is violent. Actually, Piggy fears Jack because he feels inferior to Jack since Jack is skinny and muscular and Piggy is fat, wears glasses, and has asthma.
In lord of the flies piggy is the fat boy with the specs(glasses) who is like basically a wimp. He relies on Ralph as his protection...Piggy is killed at the end of the book he is murdered he gets killed by like a boulder...i know he gets crushed
piggy can not grow hair because he is the only person on the island that remianed civilized. the other boys are growing hair because they are uncivlized and they are becoming savages.
