SCP-049 is a humanoid entity, roughly 1.9 meters in height, which bears the appearance of a medieval plague doctor. While SCP-049 appears to be wearing the thick robes and the ceramic mask indicative of that profession, the garments instead seem to have grown out of SCP-049's body over time1, and are now nearly indistinguishable from whatever form is beneath them. X-rays indicate that despite this, SCP-049 does have a humanoid skeletal structure beneath its outer layer.

SCP-049 has been acting weird around you or maybe he has a crush on you and is trying to look muscular to make you fall in love with him...

SCP 049-J: SCP 049-J is the biological offspring of SCP 049, the Plague Doctor. The "J" stands for Junior. He, loves his father. SCP 049 tends to have little patience with Junior.
