Peter Pevensie is one of the main protagonists C. S. Lewis's The Chronicles of Narnia series.
In Disney's live-action films, The Lion, the Witch and the Wardrobe and Prince Caspian, he is portrayed by William Moseley and Noah Huntley as an adult.
Peter was born in 1927 and is 13 years old when he appears in The Lion, the Witch and the Wardrobe. As a monarch of Narnia's Golden Age, he rules with his brother and sisters for 15 years, reaching the approximate age of 28 before returning to the age of 13 in England at the end of Wardrobe. By The Last Battle he is a 22 year old university student with his heart still in Narnia, though he had not been there since Prince Caspian, when he was 14 years old.
The Lion, the Witch and the Wardrobe
Peter Pevensie in the 2005 film, The Chronicles of Narnia: The Lion, the Witch and the Wardrobe. A loyal and devoted big brother figure, Peter is the oldest of the four siblings. He tries his best to protect his siblings and to act like a responsible young adult. In the book it is implied that he is more mature than his siblings because after their father was called out to fight in the war, it was left to Peter by his mother to support his three siblings through the ordeal of their father going away. He is evacuated to the countryside with his siblings by train because of the air-raids during World War II. In the countryside, they stay at the old mansion of Professor Digory Kirke.When Lucy first stumbles on the wardrobe, Peter doesn't believe her, thinking it is just her imagination until he and the other Pevensies enter the wardrobe themselves; "A jolly good hoax, Lu".(Lewis 1950, pp. 27) He later apologizes to Lucy for not believing her and is quite angry with Edmund for earlier denying Narnia's existence (Lucy had seen Edmund in Narnia before, but he had lied that they were just "pretending"); "Well, of all the poisonous little beasts".(Lewis 1950, pp. 55) This is caused by Edmund's revelation of his deceit when, upon entering Narnia, he says; "I say ... oughtn't we to be bearing a bit more to the left, that is, if we are aiming for the lamp-post?".(Lewis 1950, pp. 54–55). Peter had already been angry with Edmund before he knew that Edmund was telling lies; while not believing that Lucy had been in Narnia, he did not believe that Edmund was doing Lucy any good by jeering at her and encouraging her about her claim to have found a country in the wardrobe. During the period between Lucy claiming to have got into Narnia through the wardrobe a second time and all four siblings finally making it into Narnia together, Peter negotiates a truce between Edmund and Lucy, although his annoyance with Edmund is still visible.Edmund later strays to the White Witch (having met her when he first came into Narnia and been seduced by her promises of power) and Peter later confesses to Aslan that his anger towards Edmund (for trying to make out that Lucy was a liar) probably helped him to go on a wrong way. Peter and his siblings had been under the protection of Mr and Mrs. Beaver after arriving in Narnia, and Mr. Beaver had suspected Edmund was a traitor from the moment he set eyes on him, but did not mention anything to the others about it until his absence was noticed and Mr Beaver figured out that Edmund had gone to the White Witch. Edmund is then rescued on Aslan's orders. Meanwhile, the others all make their way to the Stone Table to meet Aslan.Peter received his sword (Rhindon) and shield from Father Christmas after meeting him on the journey to find Aslan, and is later knighted "Sir Peter Wolf's-Bane" (Lewis 1950, pp. 121) by Aslan after he kills Maugrim the wolf, chief of the White Witch's secret police, who was trying to kill Susan and Lucy. In the American editions of the books on which the 1979 animated film was based, Lewis changed the chief wolf's name to Fenris-Ulf, after a figure from Norse mythology. In those versions, Peter is given the epithet "Fenris-bane".While the great battle is being planned, he is appointed head General of Aslan's army. After the defeat of the White Witch Jadis, self-styled Queen of Narnia, and her evil allies in the Battle of Beruna Ford, he is crowned to the Clear Northern Sky by Aslan as His Majesty King Peter the Magnificent, High King of Narnia, Emperor of the Lone Islands, Lord of Cair Paravel, Knight of the Most Noble Order of the Lion. The ancient prophecy of two Sons of Adam and two Daughters of Eve coming to sit on the four thrones at Cair Paravel then comes to fruition. This marks the end of the hundred years of winter and the reign of the White Witch, and is the beginning of Narnia's Golden Age. He and his siblings finally return to their own world (where they find themselves as children once again) 15 years later, to find that no time had passed by there.
After the Pevensies arrive in the ruins of Cair Paravel, they find the castle's treasure chamber, where Peter, Susan and Lucy find the gifts they were given by Father Christmas. Peter takes his sword, Rhindon, and his shield, and again serves as the leader of the group. They eventually meet Trumpkin, a dwarf who helped protect Prince Caspian X from his uncle's Telmarine army, who accompanies them on their journey to meet Aslan.
When the children are forced to make a decision, Peter, as High King, has the final word. In order to stall the war long enough for Lucy to find Aslan and awaken the Narnians, Peter claims the right to a one-on-one duel with the Telmarine king, Miraz. After the Pevensie children help defeat the Telmarines, Peter formally gives Caspian the authority to rule a free Narnia. Aslan gives Caspian the authority to "rule under Us and under the High King". Peter later confided to Lucy and Edmund that he was told by Aslan that he and Susan will never return to Narnia, as they are now too old, and have learned all that they can from that world.
The four children returned to their world, in which they were waiting for their trains to go to their respective boarding schools.
It is learned in this book that Lucy is his favorite sister, a fact that was fairly obvious throughout the series.
Voyage of the Dawn Treader
While not physically present in the book, it was mentioned that Peter was under the tutelage of Professor Kirke in preparation for exams, but the other three children were unable to stay with him because he had moved out of the large house with the wardrobe and was now living in a much smaller house. In the film The Chronicles of Narnia: The Voyage of the Dawn Treader, Peter makes a cameo appearance at a party. When Lucy transforms herself into Susan, neither Peter nor Edmund know of Lucy or Narnia.
The Horse and His Boy
Peter does not appear in this installment, but is mentioned. While Susan and Edmund are in Calormene escaping from Prince Rabadash, he is fighting giants in the north. (Lucy is the only one left at Cair Paravel).
The Last Battle
Peter has a minor role in the story. He was the only one to address Tirian, the king of Narnia at the time, in Tirian's vision of the Seven Friends of Narnia.
After attending a dinner with the other Friends, Peter and Edmund went to London to retrieve the magic rings that Professor Digory Kirke buried in the Ketterleys' yard, hoping to use them to get Eustace and Jill to Narnia. Both were waiting for Lucy, Eustace, Jill, Digory, and Polly at the station platform when the train crashed and killed them all, temporarily transporting Jill and Eustace to Narnia until the end of the world, upon which they make their way to the real Narnia, or heaven, and meet back up with Peter, Edmund, Lucy, Digory, and Polly.
Peter is described by Tirian as having the face of a king and a warrior. After Tirian passed through the stable door and saw Tash for the first time, Peter calmly ordered the demon to leave with his prey. After passing judgement on all the inhabitants of Narnia, Aslan orders Peter to shut the door, ending the world. Peter is one of many others allowed to stay in Aslan's Country including the parents of Peter, Susan, Edmund, and Lucy.
