Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX-A is to be kept in a standard humanoid cell, no larger than 10m cubed. Standard meals are to be provided three times a day, with the inclusion of 20kg of meat to be placed in the trough by the entry. A 1m by 1m isolation booth is to be installed in a corner of the cell, with a standard camera to monitor live feed setup to outside the cell. Any personnel entering for any reason is to announce themselves over the intercom to SCP-XXXX-A and ensure entity is within isolation before entering.
Description: SCP-XXXX-A appears to be a caucasian male, of around mid twenties, with black hair and eyes. Nothing is physically remarkable about it, and mentally it is just as would be expected for age.
SCP-XXXX-A was captured and brought to site [EXPUNGED] following reports of a murder. Matter was brought to foundation attention when police who attempted to apprehend the culprit reported suddenly being attacked by an unseen force, resulting in third degree burns and gouges of flesh appearing to be 'bitten off'. Suspect was tranquilized and brought into foundation custody, where an interview indicated the existence of SCP-XXXX-B.
SCP-XXXX-B appears to be some sort of entity that has attached itself to it's host as a sort of guardian. According to SCP-XXXX-A, SCP-XXXX-B has the appearance of a green Dragon, complete with four legs and two wings. It appears to be very real, despite being undetectable by all methods tested. Curiously, it only seems to exist as long as SCP-XXXX-A is concious and has its eyes open. It appears to attack anything and anyone it deems a threat to it's host, and otherwise occupies itself by sleeping or playing with objects around it.
SCP-XXXX-A expressly states that it cannot control the entity bound to it, short of closing
