Maugrim

"Be still Stranger or you'll never move again!" Maugrim (canonically known as Fenris Ulf) was a ferocious talking wolf, the captain of the White Witch's Secret Police at the very end of the Long Winter.

Bio
He first led the raid of Tumnus' Cave where the Faun Tumnus was captured and his home left in tatters. He also left a letter to warn/scare others in his home.

Maugrim encountered the human boy Edmund Pevensie while guarding the White Witch's Castle courtyard.

He later spied on Aslan's Camp until being revealed by Susan Pevensie and the sound of her horn. Her oldest sibling, Peter met Maugrim in battle while she fled into a tree. Although Peter at first missed Maugrim with his swordtip, as the wolf howled formidably, he was able to then push the blade into Maugrim's heart. The wolf captain died a few moments later, never ceasing his biting and scratching the whole time.

Trivia

 * When given the opportunity to make changes to the texts for publishing the book in US territories, Lewis (amongst other revisions in the book) changed his name to Fenris Ulf (and therefore also Peter's title to "Fenris Bane") after which these changes were reflected in american editions of the books. Even though Lewis probably had a good reason to change the name, the current Narnia publisher, HarperCollins, in 1994 decided to use Lewis earlier, unrevised texts to publish today (and also re-order the books so they reflect internal chronology; a change which is also disputed), which refer to him as "Maugrim". This decision has led to the Character now being most widely known as "Maugrim", even though many consider his canonical name to be Fenris Ulf.
 * Maugrim's name is supposedly derived from the words "maw" (mouth) and "grim" or possibly "morgue grim".
