Per 
Special Containment Procedures: SCP-XXXX instances are to be kept in a hermetically sealed containment unit of at least 3x3x4 meters lined with 10 centimeters of lead to prevent exposure to ionizing radiation. No more than 10 instances should be kept in said chamber, but if necessary, more can be contained, albeit with significant risk. All personnel are not to enter a 5 meter radius of any SCP-XXXX instance, even through any sort of barrier. SCP-XXXX instances are not to be interacted with or tested on without the presence of a temporal sink slowing temporal flow to 1/100th times average.
As of 29/05/211, all instances of SCP-XXXX-2 are to be terminated immediately to avoid a containment breach.
In the event of a containment breach, localized or site-wide, all doors leading to SCP-XXXX's containment are to be locked down and ventilation systems are to be deactivated. If any instances of SCP-XXXX manage to breach containment, one D-Class personnel is to lead the instance along the predetermined evacuation route to the main gate, and at least 50 meters away from any structures. The instance is then to be terminated via firearm.
Description: SCP-XXXX are spherical black organisms ranging from 20 cm to 25 cm in diameter. All instances of SCP-XXXX are completely blind, but can navigate their surroundings by rolling around and detecting minute changes in the air pressure. The skin of SCP-XXXX instances reflects little light, absorbing on average 85% of light on the visible spectrum. SCP-XXXX instances will occasionally self-replicate, which is currently their only known method of reproduction, however, the process will only occur if there is enough room for an additional instance of SCP-XXXX in the instance's environment. The self-replication takes at least 1 hour to complete, and only occurs on average 3 times annually. SCP-XXXX-1 instances do not appear to have an ideal habitat, needing no food, water, or gas to create energy.
SCP-XXXX-1 is a previously undiscovered type of matter. When exposed to Hume levels in excess of 0.5, SCP-XXXX-1 will instantly reduce the Hume level of a small perimeter to 0 Humes, how it does so is unknown. An average instance of SCP-XXXX-1 contains an estimated 3 hundred-billionths of a gram, enough to annihilate most reality in a 1-meter radius. The process by which SCP-XXXX-1 creates this substance is currently unknown, and attempts to study it have resulted in understandably significant damage to personnel and equipment. Use of a Scranton Reality Anchor has proven relatively useless, as the annihilation occurs instantly and irreversibly.
When an instance of SCP-XXXX detects motion exceeding speeds of 3 km/h within a 5 meter radius that is not another instance, it will use short, tentacle-like appendages to roll itself towards the source at speeds between 5 to 8 km/h, and subsequently annihilate itself when within a short radius, estimated to be 50 cm. The reason for this behavior is unknown, as both the target object and each instance of SCP-XXXX are destroyed. The SCP-XXXX instance self annihilates by rupturing an internal organ containing only SCP-XXXX with an environment of 0.4 Humes. As soon as the SCP-XXXX-1 inside SCP-XXXX is exposed to higher levels of reality, it annihilates both itself and the target. The way SCP-XXXX maintains the low-reality space is unknown. Exposure to a temporal sink with the settings specified in SCP-XXXX's special containment procedures will delay the detonation process to approximately 3 minutes, providing enough time to remove any valuable assets from the annihilation radius.
SCP-XXXX instances are vulnerable to typical injury, however, this is ill advised, as many injuries risk rupturing the organ in SCP-XXXX. Testing involving injuring instances is barred unless given XXXX-4 level clearance. Tests have determined that damage from extreme temperatures, air pressure, and levels of ionizing radiation are ineffective in causing harm or a detonation, and will often aggravate the instances into attacking nearby movement with greater speed.
As of 18/02/21, SCP-XXXX instances have been occasionally observed congregating in close groups, and after a period of 30-45 minutes, will fuse on the cellular level. The resulting organism is proportionate in size to the SCP-XXXX instances that create it. The organism will adhere to the wall. This organism will, after a currently indeterminate amount of time, produce anywhere between 3-15 instances of SCP-XXXX. This structure has been designated SCP-XXXX-2. If SCP-XXXX-2 takes damage, it will separate into instances of SCP-XXXX.
Initial Recovery: SCP-XXXX first came to the Foundation's attention during March of 2017, after a series of buildings were unexplainably destroyed in ████████, ██ USA, notable for its recent asteroid impact outside of town. Foundation personnel found 92 SCP-XXXX instances in the sewer system. 10 out of 15 field agents were killed during the encounter, after which MTF Epsilon-6 ("Village Idiots") were tasked to contain the anomaly and deal with cleanup. Epsilon-6 successfully contained 36 instances of SCP-XXXX, with only 3 casualties. The incident was covered up under the guise of spontaneous combustion of methane gas in the sewer systems. Various other instances have been recovered worldwide, with the only discernible pattern being all sites were recently subjected to an extrasolar impact.
Incident Report XXXX-1: On 02/09/18, researcher Alexis Teroba lost his footing near SCP-XXXX containment, and unintentionally entered the prohibited range of 5 meters. An SCP-XXXX instance detected this intrusion and self-annihilated, destroying the additional 6 specimens in its containment as well as the containment chamber itself. Researcher Teroba was unfortunately lost in the accident.
Addendum XXXX-1: X-Ray imaging revealed an instance of SCP-XXXX, created on 17/04/19, did not possess the organ that produces and contains SCP-XXXX-1, subject was removed for observation. Researchers have described SCP-XXXX as having "a consistency similar to cotton, with a density similar to aluminum," and being "somewhat moist." SCP-XXXX instances have been revealed to weigh approximately 15 kilograms. Tissue samples and genetic testing revealed no relations to any known species. Notably, the instance with the absent organ did not attempt to self-replicate at all. The instance has been placed in a separate containment unit in the event it is needed for further testing.
It is now believed that SCP-XXXX is of extraterrestrial origins, due to its genetic differences comparable to life on Earth, along with circumstantial evidence, such as the original recovery location. Foundation automated observatories have been calibrated to identify potential SCP-XXXX biomass on extraterrestrial bodies.
Excerpt from psychiatric evaluation of Head Researcher Willem Brambelli:
Psychiatrist: Dr. Liu
Dr. Liu: Tell me about this recurring dream of yours, Willem.
Head Researcher Brambelli: I wake up - or at least I think I do - and I do what I usually do when I wake up, I look out the window to clear my head. That's when I see it.
Dr. Liu: What do you see?
Head Researcher Brambelli: I'm not even fucking sure! It looks like XXXX, but it's massive. I-it's bigger than anything we've got here! It's in the gaps between the stars, and I can feel it. It hates us.
Dr. Liu: Can you describe this "monster"?
Head Researcher Brambelli: It's more animalistic than XXXX, like a massive octopus, but flat, it covers the sky. The night is darker than even on a new moon, it's taken the stars. [Pauses] Do you want to know the worst part? It feels real. I feel like I'm in someone else's body, seeing this happen. We need to learn more about XXXX, because if this IS real, we need to be ready.
Dr. Liu: It's normal for people who deal with anomalous objects and creatures to feel a sense of derealization, and even lucid dream.
Head Researcher Brambelli: Do you even believe me?
Dr. Liu: Some anomalies have been known to cause dreams, but nobody else has reported these dreams before. I would suggest you take some time off, stop working overtime. You need some quality sleep.
Head Researcher Brambelli: No wait! I know what I'm talking about, I know this is real!
Branbelli’s obsession with his work and his aggressive temper, along with his consistent nightmares, have made him a liability. It is my recommendation that Head Researcher Brambelli be temporarily placed on mental health leave from 19/04/20 to 09/05/20 - Dr. Liu
Incident Report XXXX-2: On 29/05/21, a large hole appeared where an instance of SCP-XXXX-2 was rooted on the wall, and SCP-XXXX tissue was observed growing out of the hole. It is currently unknown how SCP-XXXX-2 breached containment, but current theories propose that SCP-XXXX-2 exposed the containment interior to minuscule amounts of SCP-XXXX-1, therefore degrading the structure. SCP-XXXX-2 instances are now to be terminated as quickly as possible.
Addendum XXXX-2: As of 17/08/21, SCP-XXXX biomass has grown substantially, now weighing 12.3 kilograms.
Incident Report XXXX-3: SCP-XXXX biomass, now weighing 82 kilograms breached containment on 14/07/22 under supervision of Head Researcher Willem Brambelli. Significant damage was sustained in the office outside the containment chamber before on-site security could arrive and recontain the anomaly. Head Researcher Brambelli's uniform was recovered, however, he was never located. Senior Researcher Aaron Kawne has been instated as emergency head of SCP-XXXX research.
Addendum XXXX-3: SCP-XXXX biomass has begun restructuring the now 157 kilograms of mass. It has rearranged itself into a humanoid shape approximately 2.1 meters tall, and is highly aggressive. Foundation scientists now theorize that SCP-XXXX is not the true anomaly, but rather a byproduct of a larger, more dangerous anomaly. Read revised entry for more information.
