In "The Chronicles of Narnia," the lion is named Aslan.
Aslan is the central animal character in C. S. Lewis’s seven-book Narnia series. He is a talking lion, the King of Beasts, and the son of the Emperor-Over-the-Sea. He serves as Narnia’s ultimate ruler, protector, creator, and spiritual guide.
Aslan first appears in the 1950 novel "The Lion, the Witch and the Wardrobe," where the Pevensie children learn that his return signals hope for Narnia. He sacrifices himself to save Edmund from the consequences of betrayal, then returns to life through the deeper magic. This storyline is widely understood as a Christian allegory, with Aslan paralleling Jesus and the biblical “Lion of Judah.”
A common mix-up is confusing Aslan with Prince Caspian, who is a human ruler, or with Peter and Edmund, who are visiting children. The name itself is also meaningful: “aslan” means “lion” in Turkish. Aslan is the only character to appear in all seven Narnia chronicles.
