Puppet Nurses are monsters in Silent Hill. They are real nurses that have been possessed, caught in the Otherworld. They also have a male counterpart called Puppet Doctors. They are found in Alchemilla Hospital and Nowhere.
The most distinguishing feature of the Puppet Nurse is the large, slug-like parasite that grows out of their backs, causing them to hunch forward when they walk. The parasite itself is portrayed as a separate living entity, as it can be seen moving independently from the nurse's movements, and usually dies shortly after its host body dies. The parasite that controls the Nurses is the same type that controls Cybil Bennett after she becomes possessed. Puppet Nurses can be seen with blue or green attire, as well as different hair colors.
The nurses wield scalpels as weapons, wandering the hospital with sluggish, slow movements all the while voicing repulsive, groaning noises; this dismal moaning becomes even more intense when attacked and killed. They sometimes cooperate; a Puppet Nurse may grapple Harry Mason while another one stabs Harry with a knife. This cooperation is a common characteristic among parasitic hosts, even in the real world. When the Nurses are knocked down by a strong blow such as the hammer, they will flail and struggle on the ground wildly before going limp.
The nurses represent Alessa Gillespie's fear and hatred of nurses, seeing as they were always around her when she was admitted to Alchemilla Hospital after her serious injuries.
Although they weren't necessarily members themselves, they were acting as puppets of the Order by keeping her alive, further attributing to their name and symbolism of their monstrous forms.
