Peter is a young boy who lives on the island of Never Land. He has a pixie who is his best friend and sidekick and is the current leader of the Lost Boys.
Peter was a little boy. When he first met Wendy, she tried to speak to him, but he couldn't care less. He was also depicted as caring when he realized Wendy didn't want to grow up so he decided to take her to Never land with him. Wendy's brothers Michael and John also joined the adventure. Over all, Peter Pan is a heroic character and is beloved by all his friends. The only thing Peter can't stand, however, is his friends' lives being threatened by Captain Hook.
Ten years before Sora ever came to Neverland and learned to fly with this childish hero, Peter Pan lived a life of bliss with the Lost Boys. When Terra, Ventus, and Aqua visited the world, however, everything changed. The boys and Tinker Bell learned of the outside worlds.

When Aqua finds the wooden keyblade, Peter tells her that Ven left it there. During the end credits, Peter is shown having stolen Hook's hat after recovering their treasure.
