peter pevensie
The eldest of the four Pevensie children. His siblings are Susan, Edmund, and Lucy Pevensie, who all find their way into Narnia. Peter is gifted a sword and becomes an extremely skilled fighter and general, leading an army into battle at least three times. At the end of The Lion, The Witch, and The Wardrobe, he is crowned High King Peter the Magnificent of Narnia and Emperor of The Lone Islands, along with his siblings who are co-king/queen.
High King Peter Pevensie the Magnificent of Narnia and Emperor of the Lone Islands is my favorite Narnia character.
