Werewolf

"I'm hunger. I'm thirst. Where I bite, I hold till I die, and even after death they must cut out my mouthful from my enemy's body and bury it with me. I can fast a hundred years and not die. I can lie a hundred nights on the ice and not freeze. I can drink a river of blood and not burst. Show me your enemies."

- An unnamed werewolf shortly before the Assassination Attempt on Caspian X.

Werewolves were wolf-like creatures that were anthropomorphic, meaning they could stand up on two legs, like men, unlike normal Narnian wolves.

Werewolves, along with Ogres, Boggles, and Hags were considered one of Narnia's darkest races.

Bio
During the Long Winter, they served the White Witch, and were present at Aslan's death. They also fought for the White Witch's Army in the First Battle of Beruna.

During the Narnian Revolution, a werewolf and a Hag had tried unsuccessfully to convince Caspian X to summon the White Witch back to life, to help rid them of King Miraz. This particular werewolf was killed shortly thereafter, but not before giving Caspian a bite.

Facts/Myths
Werewolves appeared to have the ability to turn from a man to a wolf at will. The myth goes that one only had to be bitten by a werewolf to become one, but apparently, as Caspian was bitten and yet did not change, this myth is not true for Narnian werewolves.

When in wolf-form, they were human-like wolves with white, brown or grey fur.

Trivia

 * In The Video game version of The Lion the Witch and the Wardrobe‎, a Werewolves howl could stun the player for a short period.
 * In the Prince Caspian (video game), the Werewolf can go into a frenzy that can kill the player in no time, and his howl is not that dangerous as in the last game.
 * The Werewolf in the Prince Caspian movie is portrayed by Shane Rangi.
