SCP-083 appears to be a Caucasian male aged between twenty and twenty-six. Black hair, brown eyes, and 1.83m tall. Most often wears unremarkable clothing. Subject has identified himself by the name "Duke", however he does not mind being called SCP-083 or simply eighty-three by personnel. He spends most of his time wandering the grounds of his Containment site, or in the recreation room, making conversation with the staff.
If SCP-083 is not fed blood every twelve hours, subject will become highly enraged and aggressive, attempting to break out of his containment (The sole successful attempt resulted in 11 staff fatalities). This seems to be a sort of self preservation instinct, much like that of an animal deprived of food, only on a much greater scale. When in this state, SCP-083 will actively seek out humans, and attempt to feed off of them. Subject can only be pacified if he can find a human fitting his standards for blood. When he finds a satisfactory food source, subject will become cannibalistic, completely consuming it if it is human, or, if the blood is found in a pack, he will merely drain it. Upon sating his hunger, subject falls into a comatose state for roughly twelve hours, and the feeding schedule must be re-centered around this new cycle.
