Peter Pevensie is a fictional character in C. S. Lewis's The Chronicles of Narnia series. Peter appears in three of the seven books; as a child and a principal character in The Lion, the Witch and the Wardrobe and Prince Caspian, and as an adult in The Last Battle. He is only mentioned in The Horse and His Boy in which he is away on the northern frontier fighting giants and in The Voyage of the Dawn Treader in which he is studying under the tutelage of Professor Kirke. In Disney's live-action films, The Lion, the Witch and the Wardrobe and Prince Caspian, Peter is portrayed by English actor William Moseley. Actor Noah Huntley portrays an older Peter at the end of the first film. Peter is the eldest of the four Pevensie children and shares his adventures in Narnia with his sisters Susan and Lucy and with his brother Edmund. Peter's reign was a Tetrarchy, and as "Peter the Magnificent, High King of Narnia", he had supreme authority over all subsequent Narnian monarchs. Peter is described in the book as having black hair, dark eyes and dimples like his siblings.
