The Plague Doctor is a humanoid seemingly dressed in a leather Plague Doctor outfit and mask, he speaks with an 18th century French accent. He claims to be trying to cure “The Pestilence,” an unknown disease that the doctor claims all humans carry. SCP049 is very well-mannered, respectful, and polite. He seems to truly believe what he's doing is for the greater good. Age&sickness can’t affect him. Agent Sammy is a walking corpse, he follows SCP049's orders and doesn't speak, he just growls.
