Item #: SCP-11175
Object Class: Euclid
Special Containment Procedures: SCP-11175 is to be stored in a 5 x 5 x 25 meter concrete cell with a lead lining that is at least 2 centimeters thick. He can be let out of his cell between sunrise and sunset, but he must return to his cell before sunset. He is usually cooperative with staff and will generally return to his cell 1 hour before sunset.
Description: SCP-11175 is a Caucasian male measuring about 5'11" in height and is 13 years old. SCP-11175 is unusually skinny, almost malnourished looking, despite being adequately fed. Researchers think its slender form is due to his power and/or his "possession". It is superhumanly strong and agile, and sometimes helps the guards with heavy lifting and SCP containment.
SCP-11175, though safe during the day, will turn into an animal at night. He has some control over the type of animal he turns into. Its animal forms (SCP-11175-1) are able to breath both in air and water, they are abnormally strong compared to an average member of their species, and they do not need to be fed. During these times, the animals retain SCP-11175's intelligence level (around 130 IQ) but act very differently, and are hostile towards all personnel over the age of 18. Since SCP-11175 has control over the animal he transforms into, it usually picks the least dangerous creature possible.
SCP-11175 claims to be "possessed" by an entity unknown to the foundation (Sometimes referred to as SCP-11175-2) it describes this entity as "pure darkness" that wants the "total destruction of humanity", and SCP-11175 is his "prototype weapon". It seems to have no intention of obeying SCP-11175-2, but he is still not allowed any clearance above level-1.
SCP-11175 is also able to inflict paranoia and anxiety upon all those who view it in it's animal form. To all of those afflicted, it will seem larger and, in large enough spaces, will appear to be about 1-2 feet from it's actual location. SCP-11175 claims to have no control over this.
[WIP, sorry. I might add an addendum soon.]
