Pinhead

Pinhead is a priest appearing with weirdly grey skin, pins all over his head, and a yelling yet beyond emotion cold version of calm voice that feels way more intimidating than a regular mad yell. He has a black robe, extending all the way to the bottom of him where you can't even see his legs or shoes much, long sleeves, etc. He has this thing called the Lament of Configuration. If you have the urge to open it, don't. This marks your death.
