Mor'du

Mor'du is one of the antagonists of Brave.

Brave
Mor'du is a montrous, 15 feet tall black bear with huge claws and long, sharp teeth. King Fergus lost his leg in a battle against the bear while protecting his wife and daughter.

Mor'du was not always a bear; He was a human prince, who wanted to take over the kingdom he shared with his three brothers, and used magic to gain "the strength of ten men" with a spell that eventually transformed him into a monstrous bear. Merida realizes the same spell has been thrown upon Queen Elinor as she is turned into a bear. In the end, Mor'du is killed by being crushed by a rock and the Prince's spirit is able to rest in peace.

One of the Production Designers of the film, Steve Pilcher, calls Mordu a "Demon bear" and "Moby Dick on land".

Trivia

 * Mor'du is the first Pixar villain who never says a word. He is the second Pixar vilain to be a bear, after Lots-o'-Huggin' Bear.
 * Mor'du's name actually comes from "mortus", the Latin word for "death."
 * Mor'du is the fourth Pixar villain to actually die at the end of his film, after Hopper from A Bug's Life, Buddy Pine from The Incredibles, and Charles Muntz from Up.
 * Strangely enough, Mor'du bears some resemblance to the bear that attacked Amos Slade and Copper at the end of The Fox and the Hound.
