While SCP-049 is generally cooperative with most Foundation personnel, outbursts or sudden changes in behavior are common if he believes someone to be infected. In the event SCP-049 becomes aggressive, the application of lavender has been shown to produce a calming effect on the entity. SCP-049 is a humanoid entity, roughly 8’2 ft, and bears the appearance of a medieval plague doctor. SCP-049 is capable of speech in a variety of languages, though tends to prefer English or medieval French.
