Ooze

Nicknamed "Ooze" jokingly, this creature takes on the form of an attractive woman, puppeting a corpse around with it's true self inside. Occasionally escaping as a black goo, that seeps from the eyes, mouth, and the body's scars, it has merged with the host's brain. "Ooze" keeps it's host barely alive, pumping itself through her bloodstreams, replacing the blood entirely with it's body. The creature itself can escape from the body if needed, partially or fully. Once it has left, the body will be left momenterily dead.
