Peter is the leader of the Lost Boys, which include Tootles, Nibs, Slightly, Curly, and The Twins. The Lost Boys is a band of boys who were lost by their parents after they "fall out of their perambulators" and came to live in Neverland. In Barrie's novel "Peter and Wendy" (but not the original play "Peter Pan"), it is stated that Peter "thins them out" when they start to grow up. This is never fully explained, but it is implied that he either kills them or banishes them.
