Simon

Simon is one of the biguns in the group of boys that landed on the island. Simon appears to be different from the other boys, but not to the point where he is ostracized. Simon always tries to help people as best as he can, and notices things that the other boys don't (he sees that the beast that everyone speaks of is actually themselves, and the beast on the mountain is merely a dead pilot). Because of these things, he is the personification of peace in the book. He appears to have epilepsy, due to the fact that he has a seizure at one point in the book.

When Simon sees the dead pilot, he goes to tell the others that there is no beast, but his form in the night frightens the other boys, and he is killed in a brutal melee. His body is washed out to sea.
