SCP-049 (Plague Doctor)

SCP-049 ("Plague Doctor") is dressed in a thick robe (cloak) and a ceramic mask with a long beak, typical of medieval doctors.
One with the body: In fact, the robe and mask are not worn as clothing - they have grown out of the body of the creature itself and have become an integral part of it.
Anatomy: X-rays reveal that beneath this organic shell, SCP-049 has a human-like skeleton.
Tools: The subject carries a hidden bag filled with surgical scalpels and medications that he uses during his "operations."
Character: Politeness and calmness: The subject readily makes contact with Foundation employees, speaks in a polite and intelligent tone (in English or Old French), holds himself with dignity and rarely displays outbursts of blind rage.
Obsession with the "Pestilence": The primary motive behind all his actions is to cure humanity of some unspecified disease he calls the "Great Pestilence." He sincerely believes his actions are for the greater good.
Lack of Malice (as it perceives it): It harbors no personal hatred toward humans. On the contrary, it views itself as a healer and scientist, trying to save patients, even if these "patients" are healthy by conventional medical standards. Lethality and Cold-Blooded: Due to its anomaly, SCP-049 kills any human with a simple touch of the skin (instantly halting biological functions). It then coldly performs primitive and horrific surgical procedures on the body, transforming it into a zombie-like creature (SCP-049-2).
Shy about details: Subject politely avoids explaining what exactly the Pestilence is or where he himself came from, firmly believing that only his methods are correct.
