The Evil Butcher is a tall and bulky humanoid who wears what appears to be an executioner's mask and just a few other minor leather garments. Appropriate to someone bearing such name, he can usually be encountered in the food storage of the castle.
He walks slowly while wielding a large cleaver, and once he spots a potential meal, he will hurl it straight ahead and immediately spawn a replacement in his hand.
He is a bit resilient and it will usually take more than one hit to defeat him the first times he is encountered. Crouching in front of him will let the player keep clear from his knives and allow them to attack him safely, unless he's permitted to approach close enough and inflict contact damage.
There are two variants, a green-skinned one who is encountered in the Study, and a pale-skinned one who is encountered later, in the Dance Hall. Other than their physical appearance, both are identical.
