Item #: SCP-XXXX
Object Class: Euclid (Uncontained)
Special Containment Procedures: SCP-XXXX is to be kept in a standard humanoid containment cell on level 3, hallway 12 of Site-54. The following modification has been made to SCP-XXXX containment cell: The containment cell is to be covered in a thin layer of Polytetrafluoroethylene (PTFE). Air vents should be installed in the containment cell, in order to keep it negatively pressurized.
Description: SCP-XXXX is a disfigured Caucasian male of unknown age, with a height of approximately 189 centimeters and a mass of 72.57 kilograms. SCP-XXXX has severe acid burns covering large portions of its body.
SCP-XXXX's blood is a viscous black fluid (hereby designated SCP-XXXX-1), with the exact chemical makeup to yet be identified. SCP-XXXX-1 has similar chemical properties to concentrated fluoroantimonic acid (H2FSbF6), aside from its unusual interactions with organic material. Instead of reacting as expected, organic material making contact with SCP-XXXX-1 will immediately begin to break down being deconstructing into its base components. The rate of decomposition maintains a non-linear relationship with the mass of the object in question - masses of less than 1 kilogram are broken down entirely within approximately 0.33 seconds, while masses of 50 kilograms or more are broken down within approximately 5 seconds.
SCP-XXXX is able to understand both English and Swiss German. It is unknown if SCP-XXXX is able to communicate verbally as it has made no attempts to do so. SCP-XXXX has only communicated using Swiss German sign language. SCP-XXXX will follow verbal requests and orders, but it will only communicate back if someone has made communication in Swiss German sign languages beforehand.
SCP-XXXX was found with a series of anomalous items. Each item was given the designation of SCP-XXXX-A, -B, and -C respectively. Please see the following attached documents.
Item #: SCP-XXXX-A
Object Class: Euclid
Special Containment Procedures: SCP-XXXX-A is to be kept in a modified containment locker, fitted with a similar negative-pressure system to SCP-XXXX's containment cell. The locker is to be covered in Polytetrafluoroethylene (PTFE). The locker is to be located adjacent of SCP-XXXX containment cell.
Description: SCP-XXXX-A is a modified SM-67 Swiss military issue gas mask with an 85.3-centimeter long hose connecting it to a leather pouch. SCP-XXXX-A emits a thick black vapor from the respirator staying within the frontal mask portion of SCP-XXXX-A. This vapor exhibits similar properties to SCP-XXXX-1 when exposed to organic matter.
Item #: SCP-XXXX-B
Object Class: Safe
Special Containment Procedures: All versions of SCP-XXXX-B (see Addendum XXXX.E) is to be kept within a secure storage container within the storage wing of the Anomalous Item Repository at Site-54. Researchers with level-2 clearance are able to access SCP-XXXX-B for testing purposes.
Description: SCP-XXXX-B is a set of clothing consisting of 1906 style size 12 military combat boots, black cargo pants, a 1930 style lightweight ballistic vest, a black 1920’s European style long coat, and a set of black elbow length leather gloves. The clothes making up SCP-XXXX-B are anomalously resistant to damage. During testing, they exhibited similar energy-diffusing properties to Kevlar, albeit with a far higher resistance than would be expected, and proved impervious to blunt force trauma, attempted incisions and small arms fire. SCP-XXXX-1 has no ill effects on the articles of clothing comprising of SCP-XXXX-B.
Addendum XXXX.1B: Instances of SCP-XXXX-B bear markings consistent with several Swiss manufacturers, though none can be identified as having actually produced these specific models of clothing. Reports show that each Swiss manufacturer makes items similar to the content of SCP-XXXX-B, but not the exact make and model.
Item #: SCP-XXXX-C
Object Class: Safe
Special Containment Procedures: SCP-XXXX has been granted the privilege to keep SCP-XXXX-C in their possession. SCP-XXXX-C is not to be removed from SCP-XXXX possession unless SCP-XXXX is put into a comatose state.
Description: SCP-XXXX-C a Swiss Armed Forces Identification tag from between the years of 1906 to 1934. The name “John Benson” is printed into the side, though it has been heavily defaced via the application of a sharp instrument. The word “Morthos” has been carved into the side of the SCP-XXXX-C above the poorly scratched out name. The blood type imprinted on the side does not match any of the known blood types and is listed as V-Neg. The Social insurance number listed on SCP-XXXX-C is not valid to any known person.
Addendum XXXX.1C: Upon removal of SCP-XXXX-C from its possession, SCP-XXXX exhibited an increase in hostility towards Foundation personnel, as well as increased self-destructive behavior. It is assumed that SCP-XXXX has some form of mental condition as it has created an unhealthy attachment to SCP-XXXX-C, as of 22/08/1955 it is suspected that SCP-XXXX has Combat Stress Reaction (CSR).
Addendum XXXX.D, Discovery: SCP-XXXX was found chained to a wall by the wrist, on 9/08/1955, within the ruins of a concentration camp on the outskirts of ██████, Germany, after a large tremor caused by Soviet ██████ ██████ ██████ in the area caused structural damage to the building housing SCP-XXXX.
Addendum XXXX.E, Interview log:
Interviewed: SCP-XXXX
Interviewer: Doctor Mumby
Foreword: The entire interview was conversed in Swiss German sign language and was translated for accessibility.
<Begin Log>
Doctor Mumby: “Hello SCP-XXXX, are you willing to cooperate today?”
SCP-XXXX: “I will never cooperate with you Nazis.”
Doctor Mumby: “For the last time SCP-XXXX, we are not associated with The National Socialist German Workers' Party.”
SCP-XXXX: “You lead groups of prisoners you used for force labor to gas chambers. You ignore the ‘Geneva Convention’ by refusing me my material goods, you treat me like an animal rather than a person. You lie to my face about being Nazis.”
Doctor Mumby: “We are not associated with any-”
Doctor Mumbey was cut off when SCP-XXXX started making unrecognized signs.
SCP-XXXX: “I demand to be returned home, take me back to switzerland.”
Doctor Mumbey:: “What did you say before that?”
SCP-XXXX repeated the unrecognized sign.
Doctor Mumby: “I don’t know what that means.”
SCP-XXXX turned away from Doctor Mumby putting their hands behind their back. Refusing to communicate.
<End Log>
Closing Statement: SCP-XXX has refused to communicate with any Foundation personal. Other than to make demands relating to the Geneva Convention of 1929.
Notice
Dear: Doctor Mumby
By orders of the Ethics Committee SCP-XXXX is to be granted the privilege of keeping SCP-XXXX-C in its possession. It has come to our attention that SCP-XXXX has cited the Geneva Convention of 1929 making demands for itself to be referred to as "Oberstleutnant Benson", rather than its SCP designation as per article 5 of the Geneva Convention. SCP-XXXX has also cited article 6 making demands that the entirety of its possessions is returned promptly. Due to the security risk of returning SCP-XXXX-A, and -B to SCP-XXXX a decision has been made to return non-anomalous duplicates to SCP-XXXX. Seeing as we are not required to submit to the Geneva Convention these demands may be disregarded. Although, for the sake of future cooperation, we suggest you, as well as the members on your team follow article 5.
We expect you and your team to try and reason with SCP-XXXX, but it has also come to our attention that SCP-XXXX is convinced that all Foundation personnel are members of the “The National Socialist German Workers' Party”. With every attempt at explaining that it's been disbanded and succeeded by “German Workers' Party” proving entirely fruitless. If necessary, SCP-XXXX may be subdued by force.
If SCP-XXXX continues to cite any more of the Geneva Convention we request that an apparatus report is filled out and submitted to our office. We thank you for your time.
Ethic Committee Liaison -Doctor Xilas Crowe
Addendum XXXX.F, Incidence 01:
Incidence Report
Date: 14/10/1955
At 0300 hours, four unidentified soldiers breached Site-54 perimeter. The hostile entities were able to incapacitate three of Site-54 security forces as well as 4 researchers and 2 janitorial staff. Taking Doctor Lipkin as a hostage as well as using the security force uniforms as a disguise, the hostile entities were able to make their way to Level 3 undetected. Upon reaching SCP-XXXX containment cell Doctor Lipkin tried to inform standing security and was terminated by one of the hostile entities. Standing security was able to open fire against the entities, causing the alarms to be sounded. SCP-XXXX was released from containment and was reunited with SCP-XXXX-1A, as well as given a Karabiner Model 1931 firearm.
The unidentified soldiers, as well as SCP-XXXX, were able to advance to Level 2 of Site-54 before meeting resistance from security forces. Once the tide turn in favor of Site security. The hostile entities, as well as SCP-XXXX, took hold inside laboratory 13W on Level 2 barricading themselves in. Negotiation was attempted to ensure a peaceful resolution and the return of SCP-XXXX. When no response was given, Mobile Task Force Epsilon-11 ("Nine-Tailed Fox") was deployed to provide assistance to Site security.
MTF Epsilon-11 placed several c4 charges on the laboratory's door. Upon detonation, hostile entities engaged with MTF Epsilon-11 and were successfully subdued. It should be noted that each of the hostile entities had their own set of SCP-XXXX-B.
Each of the four hostile entities, as well as SCP-XXXX, was attempted to be interviewed. This interrogation was unsuccessful, with only a single statement being made by SCP-XXXX in German sign language - "Just let my squad go home".
Addendum XXXX.D, Incidence 02: At 0230 on 16/10/1955 SCP-XXXX and each of the hostile entities from Incidence 01, as well as SCP-XXXX-A, B, and C, were discovered to be missing from their holding cell. Site’s security did a sweep of the entire Site, only to come up empty handed. Multiple search parties were sent throughout Germany. As of this time, SCP-XXXX has not been contained.
“I want SCP-XXXX and all of it’s belongings, as well as it’s friends to be sent and released at Switzerland's borders. I’m curious to see where they will lead us too. I want to know what kind of secrets are in the Swiss mountains.
O5-9 “The Secret Keeper”.
