Brother Bear (2003)

Set against the majestic natural splendor of the Great American Northwest, the film tells the story of a boy named Kenai, whose life takes an unexpected turn when the Great Spirits transform him into a bear--the creature he hates most. Befriended by a bear cub named Koda, Kenai sets out to regain his human form while his brother--who doesn't realize Kenai is now a bear--pursues him on a mission of revenge and family honor. It is a tale of courage, honor and self-discovery.
