Edmund Pevensie
Edmund, Lucy and their cousin Eustace come back to Narnia again by a painting, and end up in the ocean. They are saved and brought on board the Dawn Treader by King Caspia who is on a journey to find the three Lords that disappeared. This was Edmund and Lucy's last adventure in Narnia, because Aslan told them they were getting too old to come back. By this point Edmund had matured a great deal which can be seen in the way he deals with Eustace (cousin) and in the fights with King Caspian. Also, Edmund has completely stopped insulting Lucy. When Eustace (cousin) changes his behavior after being changed back from a dragon, Edmund mentions his own betrayal and says that Eustace was not worse than he was with the words "You are an ass, but I was a traitor".
