Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures:
SCP-xxxx is to be locked in a standard D Class barless cell. Including padded and sound proofed walls. SCP-xxxx must be fitted with a carbon fiber locking glove on its left hand to prevent usage of its cognitohazard. SCP-xxxx may not be permitted any material which may revive memories of its past, and is subject to standard D class dorm searches for contraband.
All researchers testing SCP-xxxx must wear gloves and use pseudonyms when conversing with it. Any testing utilizing a D class personnel must first be cleared with level 4 security and level 3 research. Any cadavers produced can be incinerated.
Description: SCP-xxxx-1 is an anomalous human male. currently having a height of 1.8 meters, weighing approximately 86 kg. SCP-xxxx-1’s skin is heavily tattooed, with some tattoos overlapping each other at odd angles. It is nearly impossible to see any skin beneath the tattoos. SCP-xxxx-1 has no anomalous properties physically. However is is in containment for its behavior and abilities.
SCP-xxxx-1 can, at any time. “merge” with a human of its choice. provided that they fulfill all of the following criteria:
Physically been in contact with SCP-xxxx-1 in the past ten years
Is / was on a first name basis with any iteration of SCP-xxxx-1
Has at least one Tattoo
Is alive
During a merge event, SCP-xxxx-1 will fall limp to the floor of its containment cell, Dead. This can be confirmed medically.
Following the collapse of SCP-xxxx-1, the target (henceforth referred to as SCP-xxxx-2), will also collapse, but remain unconscious. SCP-xxxx-2 will regain consciousness within a period ranging from minutes to hours. During the unconscious period of SCP-xxxx-2, rapid cell mutation occurs in 40%-60% of all cells.
Cell mutation always results in the transfiguration of SCP-xxxx-2 into a figure resembling both SCP-xxxx-1 and -2. While the new figure can be said to be similar to both original humans. The resulting entity will always have the same eyes as SCP-xxxx-1, and all the tattoos of both -1 and -2 in the original placement on each human.
Phycological tests on the resulting SCP-xxxx-2 after the mutations have revealed that the resulting personality is usually defined as somewhere between the personalities of -1 and -2 on any applied personality testing method. Of note is that this ratio is not always even between both instances. See testing logs 2,3,4.
SCP-xxxx-1 is also dangerous due to its previous history with the foundation, which was discovered to be relevant once it was determined that 90-100% of SCP-xxxx-1’s memories transfer to its new host. See testing log-04
Foundation History:
SCP-xxxx-0 (the original) was a foundation researcher in 19HH. But was demoted to D class due to misbehavior and poor handling of several dangerous SCP’s. While in D class living quarters SCP-xxxx-0 received several tattoos from other D class using scavenged ink pens. Including a tattoo on the back of its left hand that is a mild cognitohazard, resulting in nausea and dizziness. This is suspected to have contributed to its escape. SCP-xxxx-0 escaped HH months later during an unrelated major breach of security resulting in a containment breach of several SCPs.
18 months later foundation employees located an individual in police custody on suspected murder. Due to the human cadavers found in its residence. SCP-xxxx-1 then merged to an unknown individual when it discovered it had been relocated.
SCP-xxxx-1 continued to evade foundation agents for an additional 17 months. Until SCP-xxxx-1 “merged” with a victim that had a history of brain damage from fighting. SCP-xxxx-1’s mental ability was severely reduced resulting in its capture 1 month later. SCP-xxxx-1 has shown periods of compliance and of extreme noncompliance following “merge” with individuals who show similar traits.
Testing log:
Test - 02:
Researcher Dr. Willow.
Test: see what properties remain between merge instances.
Procedure: a D class Female is used as a merge target.
Note: before test, SCP-xxxx-1 has been very uncooperative. And possesses a very aggressive “alpha” personality.
Notable events:
D class is not told of her fate. D class has been selected for relaxed, unimposing nature.
D class and SCP are moved to the same cell, spending one week together.
After fulfilling all criteria. D class is moved to separate facility to prevent her true situation from being revealed
When SCP is told through rumors that she has escaped.
SCP-xxxx-1 captured in separate facility.
Result: SCP-xxxx-1 changed sex and still aggressive. Suggesting that more aggressive personalities are more preserved in a merge.
Researchers note: the Female D class used had the same mass as the resultant SCP-xxxx-1
Test - 03
Repeated test 2 with new D class
New D class Is a heavy smoker, and scores slightly below average for D class aggressiveness.
Subject is very muscular and uses physical size to get cigarettes from other D class
Result: SCP-xxxx-1 merged successfully and now has gained an intense addiction to cigarettes.
Test - 04:
Researcher: Dr. Willow (under the pseudonym of Dr. Jason Douglass)
Begin transcript:
Dr. Douglass: Hello SCP-xxxx-1, are you feeling more compliant after the results of test 3?
SCP-xxxx-1: somewhat, yes. I'm sure you could make me….. a little more compliant for a pack of cigs.
Dr. Douglass: after this test you can receive your standard D class Ration.
SCP-xxxx-1: *scowls* ah @#$% off. -incoherent mumbling-
Dr. Douglass: If you could just answer me a few questions we can finish this interview.
SCP-xxxx-1: *pause* fine what do you “researchers” want to know now?
Dr. Douglass: how many people have you “merged” with?
SCP-xxxx-1: *long pause, appears to be lost in thought* oh I don’t know… one hundred to a thousand? *grins* its kind of fun….
Dr. Douglass: Do you remember your clearance level at your first facility, before D class reassignment?
SCP-xxxx-1: *Upset* y..yes, I was level 2 research. And I would have saved you a lot of trouble if you had just let me take care off SCP-KKKK, and gotten it off your hands.
Dr. Douglass: *trying to change the subject* Hmmm, and what of your tattoo? *gestures towards its glove*
SCP-xxxx-1: Oh, I don’t know! Perhaps a loony in D class was exposed to…. Wait. screw off! i'm no snitch!
Dr. Douglass: If you withhold information I can cut your cigarette ration.
SCP-xxxx-1: *becomes increasingly distressed*
Dr. Douglass: we can try this again later.
SCP-xxxx-1: *makes a sudden movement in an attempt to touch Dr. Willow’s skin*
Dr. Douglass: *leaves the testing room at a hurried pace*
