Borin

Don't be put off by his slow movements and thought process, this is one brute you don't want to pester. 
Borin is absolutely massive, and has the strength to fit. He may seem tubby around the waist, but he's pretty much a walking ball of muscle.
His legs are very powerful, and can give quite the kick or swipe, as well as being able to crush bone with a single step.
His skin is tough and leathery, and almost impossible to piece with a normal weapon. But his underbelly is quite soft.
His skull is the toughest part of his body, and he can use this greatly to his advantage by swinging his head around to knock opponents down or give them a serious head-butt. It would be impossible to break the horns on his face. His large 'beak' is used for crushing bone, his favourite food.
He is easily startled, so you should always approach him with caution to show you mean no harm.
He gets dazed by bright lights easily, but has excellent night vision.
