SCP-4137 "The Twins of Turmoil"
Class: Euclid
SCP Information: SCP-4137 is two anamolous humanoid entities, both accordingly labeled SCP-4137-1 and SCP 4137-2. Each individual appears to be of [REDACTED] descent, yet each claim to be from [REDACTED] despite being recovered in [REDACTED]. Both individuals are quite different from one another, having inverse bodily features that directly mirror one another, which extends even to internal organs being mirrored. This is all that is physically consistent with 4137, the two entities have abstract facial features that are impossible to make sense of, being that they are a culmination of shapes that change every moment. There is no observed "rotation" to these changes as they are random and unrepeating, each different from one that has ever been displayed before, it is also unknown how these entities verbalize and if they see or not. SCP-4137-1 and SCP-4137-2 also have mirrored emotions, this is not fully understood yet but it should be noted that this does not change anything regarding the danger of 4137. 4137-1 and 4137-2 have an innate ability to know the exact location and thoughts of one another, and will make any attempt available to reach one another. When together, SCP-4137-1 and SCP-4137-2 pose a serious threat, their emotions will begin to mimic one another and their facial features will lock in whatever shape they were the moment before contact. During this event, both entities will have previously unknown memories of what appears to be every living being on the planet, and uncanny knowledge of their surroundings at all times. The two entities will then attempt to release all other SCP's on site [REDACTED] before leaving to find what they have stated to be "The Middle". No location corresponding to this stated area has ever been located, and on all of the ventures SCP-4137 have taken during breaches, it appears that this location has no set area. During the venture that SCP-4137-1 and SCP-4137-2 take to get to "The Middle", every thing living that both entities touch will die in various fashions, including observed cardiac arrest, spontaneous combustion, complete cellular death, various diseases, immediate generation of stage 4 cancers, and sudden appearance of many fatal wounds on the body. It is unknown how these effects are caused by 4137, but it is known that all touches have an almost 100% mortality rate and leave a handprint wherever the victim was touched(See addendum 4137-1). Both entities will intentionally seek out life and kill it which makes them especially dangerous, but also makes them easier to contain as they will attempt to not leave behind even a little bit of life before they move forward towards their target location.
Special Containment Procedures: SCP-4137-1 and SCP-4137-2 are to be contained on site [REDACTED]. Each individual is to be placed in a 10 by 15 meter container made of rebar reinforced concrete and elevated 12 meters off the ground and placed inside of another another container which is made of titanium 1/2 meter thick and double the dimensions of the primary containment chamber. All monitoring of SCP-4137 is to be limited to 10 minutes at a time and must be okayed by O5. Conversating with either individual is strictly prohibited except under special occasion due to possible change of the SCP's emotions caused by conversation. SCP-4137 will sometimes communicate with one another and this is to be monitored very closely and written down for every spoken word between one another.
Addendum 4137-1: CONTAINMENT BREACH, SCP-4137-1 and SCP-4137-2 breached containment and after releasing all on site SCP's, headed towards the town of [REDACTED] causing roughly 700 casualties and proceeding onwards before being captured and recontained along will all other on site SCP's. Although SCP-4137-1 and SCP-4137-2 had touched about 700 people, not all were found which was later discovered why. After recontainment, SCP-4137-1 began repeating what was originally impossible to understand words which eventually came to be distinguished as coordinates. When teams were sent to this location, which was a barren desert that was previously known to be the city of [REDACTED]. It is unknown how [REDACTED] came to be this desert, but multiple foundation agents seemed to not remember a city ever existing in that space. On the direct coordinates that SCP-4137-1 had stated stood a caucasian man, average build, about 5'10"(Who will now be referred to as SCP-4137-3). After further inspection, the man's eyes were completely black, and he was unresponsive to questioning. However he was speaking, it's unknown who to though (See Incident 4137-1)
Incident 4137-1:
MTF: Sir, what is the purpose of your being here, explain immediately.
SCP-4137-3: I must not be here, I must not live, I must not exist, I must not-
He trails off before looking directly at MTF and shouting
SCP-4137-3: I must not move!
It's at this point that SCP-4137-3 is observed to have the handprint consistent with all SCP-4137 victims. It also is observed that SCP-4137-3 is not breathing, or alive, having no infrared signature.
MTF attempts to grab hold of SCP-4137-3, handcuffing him and moving him about 3 feet before SCP-4137-3 says "I told you, I must. Not. Move." Which after being stated 4137-3 disappears and reappears at site [REDACTED] and is shot multiple times, which appears to do nothing. After being shot approximately 40 times, SCP-4137-3 frees 4137-1 and 4137-2. Both 4137-1 and 4137-2 touch the shoulder of 4137-3 and he falls to his knees still for approximately 30 seconds before maggots crawl out of his mouth and consume his body. SCP-4137-1 and 4137-2 are recontained after approximately 60 staff casualties. Any more coordinates given by 4137 are too be located and in the event of another person being located at the coordinates, they are not to be moved by any means. Disappearing of areas and life around the coordinates given is to also be recorded. It is unknown if this SCP is mind manipulating because some MTF seemed to not know of the city that was missing on the coordinates given.
