Keaton is a werewolf featured in Fire Emblem Fates. He is a playable character in Conquest and Revelation, and a minor antagonist in Birthright. His default appearance is that of a humanoid with wolf ears and tail, but he can use a magical artifact known as a "beaststone" to transform into a feral wolf monster. He is the father of Velouria and a potential love interest for Corrin. In Revelation he develops a friendship with fellow shapeshifter Kaden, who is a kitsune.

Keaton is a hoarder who enjoys collecting gross and strange things, such as bugs and corpses.
