Fablehaven is home to approximately two dozen minotaurs. Part man, part bull, these beasts stand a head taller than most men and come in various shades of fur, from chestnut brown to black. They have wide horns, a bulky musculature, and reek like livestock. The minotaur has an acute sense of smell. It is extremely strong and prefers heavy weapons such as the mace and battle-axe. These hefty weapons can slow down a minotaur, giving quick opponents and advantage.
They make appearances in the second, third and fifth books. In Rise of the Evening Star, Warren fights one who is placed to guard the way to the artifact in the inverted tower. In Grip of the Shadow Plague, several are stationed to guard Kurisock's domain at the battle between light and dark creatures. in Keys to the Demon Prison, a horde of them are killed by Bracken while trying to kill Civia.

Some minotaurs are members of the staff that serve and assist the caretaker of Wyrmroost.
