This is Pinch. Pinch is a plague doctor. He is the result of seeing plague doctors absolutely everywhere for a month. (Oh, look, another plague doctor picture on Deviantart. Oh, look, all the doctors in AC2 are plague doctors. Oh, look, a plague doctor adoptable on Squiby.) I'm pretty sure the universe was telling me to draw a plague doctor, so I did.
Anyway, Pinch is some kind of bird person, so that is his actual face and not a mask. Although he is in fact wearing pince-nez glasses, and his beak doesn't move when he talks. Even though he looks like a creeper, he is actually a very friendly guy, and he likes to poke things with sticks. For science. I think his robe is some kind of flowy-shadowy thing, I'm not sure yet. I'm also not sure if he is actually some kind of eldritch abomination in disguise.
