Bone Leech

The Bone Leech is a nuisance enemy from Blood II: The Chosen. It is a face-sized parasite resembling a leech or eel with pincers protruding from its flesh, originating from Reality Beta. It infects by attaching to the victim's face and inserting its pincers. The victim either loses consciousness or dies, at which point the leech enters the chest and attaches to the spinal nerves. At this point the leech takes control and metamorphoses the body into the stages of Soul Drudge, Drudge Lord, and finally Drudge Priest. They are often found in bathrooms, pools of water, sewage, or other fluids.
