General Otmin is the quaternary antagonist in the Disney movie, The Lion, the Witch, and the Wardrobe which based on the Chronicles of Narnia book series. He is the minotaur and the commander of The White Witch's army.
He is much larger and stronger than other minotaurs, who are tough beasts already. He wields a huge double-bladed axe, and a long scimitar. Otmin leads the first wave of the villain army during the final battle. In that battle, he fought Orieus, the Narnian army's lead centaur. Orieus eventually killed Otmin by stabbing him through with both of his swords.
Otmin does not appear the the book, and was created for the movie. Minotaurs were, however, mentioned as being in the White Witch's army.
