Minotaurs come in two forms, the standard or advanced minotaur (beast legs, human torso, bull head), and the savage bestial minotaurs.
The bestial minotaurs in are large bulls with a slight humanoid touch. They have the head, torso and hind-quarters of a bull but with two large human arms. They run on their hands and legs like oxen (with clenched fists), but they occasionally stand on their hind legs and walk around.
