In The Chronicles of Narnia: The Lion, the Witch and the Wardrobe, Aslan is a lion.
Aslan is the central majestic figure of Narnia and the son of the Emperor-beyond-the-Sea. He guides and protects the Pevensie children while opposing the White Witch’s rule. His arrival is associated with the return of spring and the restoration of Narnia from the Witch’s endless winter.
C. S. Lewis presents Aslan as a powerful, wise, and compassionate character rather than as an ordinary talking animal. He serves as Narnia’s rightful ruler and appears throughout the larger Chronicles of Narnia series. The character’s name and imagery draw on the Turkish word for “lion.”
Aslan is sometimes confused with other important Narnian creatures, such as Mr. Tumnus, a faun, or Reepicheep, a mouse. The White Witch is also not an animal; she is the humanlike ruler responsible for Narnia’s winter. Aslan’s animal form is one of the most recognizable features of the series.
