They are possessed by the same unspecified parasite infesting the Puppet Nurses, causing them to also have a similar hunchbacked appearance. They wear standard hospital gear, including a white lab coat and tie.
They appear in a white jacket and a black tie with a lump on their back. They are hunched over like a puppet and attack with knives. They are few and far between in the Otherworld version of Alchemilla Hospital, appearing only on the first floor. The Puppet Doctors make terrible groaning noises and when defeated let out a long sigh. They are stronger than Nurses, but they are also slower. It is best to use the hammer on them.
The parasite infecting the doctors and nurses could possibly represent Alessa's feeling that the entire hospital was being controlled like puppets under the influence of the cult and the drug PTV, which Michael Kaufmann was supplying. They may also represent Alessa's hatred of doctors, which was caused by her confinement in her hospital room.
- To date, these are the only male medical staff to appear as enemies in the Silent Hill franchise; in later games, the hospital-based monsters are all female.
