Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures:
SCP-XXXX is to be kept at Site 19, in building █, level █. The cell is 24 by 34, made out of rubber, concrete and steel, and is surrounded by █ layers of the same materials. At least 2 MTF squads are to guard the cell 24/7. If any surveillance camera goes out, contact Dr. Longside immediately, and wait for further instructions.
Under NO circumstances should any personal of any clearance enter and approach XXXX’s cell without Dr Bright or Dr. Longside, and Junior Researcher Argent, present. If SCP-XXXX is seen wielding SCP-XXXX-2 in a threatening manor, a full lockdown of Site-19 must be initiated, and immediate contact to Dr. Longside. If SCP-XXXX escapes containment, and is not stopped by Junior Researcher Argent, a resulting XX class end of the world scenario could occur. A possible solution to this event is underway
Every 24 hours, Junior Researcher Argent MUST enter the cell, and spend around and hour and a half with SCP-XXXX, to prevent a rise in emotion, as emotion is what seems to control the amount of power SCP-XXXX-2 has.
Description:
SCP-XXXX is a humanoid entity resembling a caucasian female of around 19 to 20 years, average height, weighing in on 56.69 Kg, having black hair, and red-green eye’s. See SCP-XXXX-1 for more details.
SCP-XXXX is capable of speaking in almost every language known to man, and a few extinct languages as well. SCP-XXXX is non-hostile to staff, but does not particularly like being bothered. The 'purpose' of SCP-XXXX, besides following around it's designated holder, Argent, is unknown. Due to the nature of SCP-XXXX-2, it is assumed SCP-XXXX was designed to end the world or save it. SCP-XXXX will become extremely hostile to any entity that threatens Junior Researcher Argent's life or safety, breaking through all forms of containment, while it's current cell only slows it down. The element Titanium mixed with Tungsten seems to have a weakening affect of SCP-XXXX, making it seem sluggish, and cannot seem to destroy it. Containment cell update pending.
SCP-XXXX wields a large, longsword-railgun hybrid, known as SCP-XXXX-2 that is usually summoned out of what seems to be akin to SCP-106's pocket dimension. The summoning process can take from 5 to 30 minutes, giving a range for Agents to possibly stop it with high caliber artillery. The cannon itself is capable of vaporizing an 5in thick concrete barrier within 4 minutes, and seems to grow more powerful the angrier SCP-XXXX gets. It is theorized that if Junior Researcher Argent is killed, SCP-XXXX would go out of control, and cause a XX class end of the world scenario.
Addendum XXXX.01 . Recovery.
SCP-XXXX was discovered in a deep under ground cavern in Kansas by Junior Researcher Argent. After the then non Foundation-employed Argent came into physical contact with SCP-XXXX, it awoke and stated it’s mission statement. (See Log-1). Argent was followed by SCP-XXXX for 10 days, until Incident 1 occurred, and the Foundation was alerted. When agents arrived, SCP-XXXX was wielding SCP-XXXX-2, standing in front of a shocked Argent. A agent opened fire at SCP-XXXX, resulting in SCP-XXXX to incident Incident-2. The Foundation managed to get Argent to bring SCP-XXXX to Site 19, as the heavy caliber gun fired at it did no damaged, and seemingly bounced off SCP-XXXX's armor and skin.
Argent and SCP-XXXX were questioned separately. SCP-XXXX refused to speak to the interviewers at all, just staring with suppressed anger. Argent, however, was much more forthcoming than SCP-XXXX. (See Interview 1). After the interview, a conference was held to decide Argent's fate. Dr. Longside and Dr. Bright, at Site-19 after alerted of a powerful entity, argued that he had use for the Foundation, but were outvoted on the use of Class-B Amnestic's. When Dr. ████ approached Argent with the Amnestic, Incident-2 occurred, resulting in the halting of the procedure. Another Conference was held, and it was decided to 'recruit' Argent into the foundation, making him a Junior researcher, due to his knowledge of Biology, Mechanics, and the paranormal. Junior Researcher Argent is currently working under Dr. Longside and Dr. Bright, when ever he is around. Bright seems to have taken a liking to Argent, as they share some hobbies in common.
Addendum XXXX.02 Possible weaknesses
SCP-XXXX seems to have a minor mental disability resulting in the loss of the ability to read, and comprehend letters, and gets frustrated when someone shows it a book. SCP-XXXX also seems to be affected by coolant used in nuclear reactors. When exposed to coolant, the subject visibly shivers, looking panicked. When applies to the subject, motor function stops, and SCP-XXXX is immobile, and unable to summon SCP-XXXX-2. After this test, Incident 4 occurred, and the idea was quickly shelved. It is also theorized that hitting SCP-XXXX or SCP-XXXX-s's core with a large shot from SCP-044 could possible eliminate the entity, currently under consideration.
Addendum XXXX.03 The Link
SCP-XXXX has always seemed to have been bonded with Junior Researcher Argent since he first made physical contact. Re-exploration of the cave SCP-XXXX was found in revels it to be a machine-like humanoid with human-like parts. Using X-Ray's and █████, SCP-XXXX is seen to have a module attached to it's 'brain', that is used to identify a suitable care taker, by unknown means. Text gleaned from the cave revels that SCP-XXXX is possibly from another dimension, and traces of a sort of Tungsten-Titanium coating around the cave suggests primitive containment. A foundation logo was found deeper in the cave, with Dr. Bright surmising that a incident akin to SCP-1730 happened in the cave system, with him even theorizing that during SCP-1730's original time shift, it dumped SCP-XXXX into this reality, as further examination revealed the room to be a containment cell, badly damaged to the point of non-recognition. Further exploration into the cave has been halted until unmanned drones can be sent down safely.
