Doctor

An unknown entity that haunts hospitals and frequently disguises itself as a doctor, hence the name people call it. It has a very loose grasp on the English language.

Doctor masquerades as a mortal and continues living by eating people alive and stealing their hearts. The heart in it's chest cavity must be replaced once the old one rots. It does not have malicious intent and does not understand mortal emotions.

It's behavior is strange when encountered, with it almost never making eye contact until killing. Interacting with it is strange and almost nonsensical.
