Specimen of SCP-X, 5 minutes after insertion of biological matter from a specimen of Felis silvestris catus (The common 'house' cat).
Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: Up to 10 instances of SCP-X-1 can be kept in a safe in secure storage for testing purposes. Excess instances of SCP-X-1 should be destroyed. Any instance of SCP-X-2 outside of a controlled testing environment should be destroyed immediately via incendiary weapon. Testing is prohibited unless permission is given by at least 2 Senior Researchers, one of whom must oversee the test.
Testing of SCP-X must be performed in a room less than 3x3x3m in size. This room must have an air humidity level of less than 5% during testing. The surface on which testing is performed must be coated with lead. The walls of the room must be completely fireproof, and the floor and ceiling outfitted with miniature flamethrowers capable of 60 seconds of sustained fire. In the event of a containment breach, MTF Team Gamma-13 ("Greek Fire"), equipped with flame-retardant lead-lined HazMat suits and flamethrowers will be dispatched to terminate the instance(s) of SCP-X-2.
Description: SCP-X is a sealed test tube (from now referred to as SCP-X-1) in clamshell packaging branded as "Life in a Tube!™". The packaging advertises itself as "a fun science experiment for kids!" and that it "Just needs 1 fingernail!". The company name "Kool Science Ltd." is listed on the packaging, though no company under that name is known to exist. The liquid within SCP-X-1 is seemingly non-anomalous water.
SCP-X-1 displays its anomalous properties when biological matter from any species of mammal is introduced to it while it is at least 50% full of water (this will only happen if the water is what was originally in the test tube; draining the test tube and replacing it with new water will not work.). When a sample of biological matter becomes submerged in the water, a layer of flesh identical in genetic makeup to the sample will begin to grow on it. The water in the tube will disappear at the same rate as the flesh grows, presumably being converted into flesh through anomalous means. Once all the water has been incorporated into the mass of flesh (from now on referred to as SCP-X-2), SCP-X-2 will begin to excrete an unknown liquid which liquefies most materials (at varying rates; organic materials are liquefied quickly, while heavy metals, especially lead, do so much slower). SCP-X-2 will then absorb the liquefied matter and, through anomalous means, convert it to flesh. As SCP-X-2 grows larger, this liquid becomes more potent.
As SCP-X-2 grows, it gradually takes the shape of the creature that the biological matter sample originated from. Its anatomy, however, can vary in similarity to the original animal. For example, the specimen in the photo above grew into a creature similar to a cat, though it was hairless, lacked eyes, grew fleshy tendrils in the place of whiskers, and had a digestive system that terminated at the stomach (likely due to SCP-X-2's absorption-based feeding method). Regardless of features, SCP-X-2 instances seem to have exceptional senses of smell and hearing. The most notable difference between all instances of SCP-X-2 and their respective parent fauna is the complete lack of a brain. In its place are bundles of nerves located near sensory organs in the SCP-X-2 specimen's body. SCP-X-2 instances can grow to sizes much larger than the animal they originate from (see Breach Log X-2-B3 for an example.). Once a specimen of SCP-X-2 reaches a critical size (currently unknown, estimated to be roughly 2 tonnes), it will collapse into an amorphous mass, which will then split into up to 10 smaller versions of itself (similar to the form it took pre-collapse).
SCP-X-2 instances are universally hostile towards animals and will attempt to assimilate other animals into its own mass. Typically, The SCP-X-2 instance will attack the spinal cord near the point of attachment to the brain stem, either with claws, teeth or by dissolving the spinal cord with the liquid it excretes. This leaves the target paralysed and defenseless against SXP-X-2, which can freely dissolve and absorb the victim. Despite a lack of a central brain, SCP-X-2 instances are very intelligent hunters, being able to recognise when they are outnumbered and attempting to disable assailants to minimise harm to themselves.
[Date: ██/██/20██, Location: 2.█km South-West of █████, Texas]
21:37: Police are called to the ██████ family house by the father, George █████ (Audio transcript of the 9-1-1 call can be found in Addendum SCP-X-A2.)
21:38: Implanted Foundation agent in █████ County Police Force calls for an MTF team to be dispatched to ██████ family house after learning about the nature of the call from a police officer.
21:45: MTF Team Phi-7 ("Wildlife Control") arrives at the ██████'s house. On audio recordings from Capt. ████████'s jacket microphone, screaming can be heard from within house. MTF Unit 2 suggests that it is coming from second floor of house.
21:46: All MTF Units prepare for engagement, activate helmet flashlights, and enter home. Unit 2 affirms screaming is coming from up the stairs.
21:47: All units move upstairs. Capt. ████████ commands Unit 4 to look into room on left side of the landing at the top of the stairs. At this point, screaming has become loud gargling.
21:47: Unit 4 looks into room, loudly shouts an expletive, then pulls his head back. Sound of a dog barking can be heard.
21:48: Instance of SCP-X-2, taking the form of a massive (estimated to be around 1,100kg) dog covered in scales and with 6 eyes, runs out of room and turns to face MTF Squad. Units 4 and 6 begin firing upon it. Bullets do minimal damage to SCP-X-2 instance, which growls and leaps at Unit 4.
21:49: Units 3 and 5 retreat down the stairs to the bottom floor where Capt. ████████ and Unit 2 are. SCP-X-2 lands on Unit 4, pushing him and Unit 6 down the stairs along with it. Unit 6's head hits the banister rail of the staircase while falling, knocking him unconscious and cracking his skull. Unit 4 is also knocked unconscious when he hits the floor at the bottom of the stairs.
21:50: Capt. ████████ along with Units 2, 3 and 5 immediately open fire upon SCP-X-2. Bullets do minimal damage to SCP-X-2. The instance tries to attack Capt. ████████, but Unit 2 lures it away from him, taunting it and continuing fire, aiming for its eyes. Unit 2 runs into the kitchen and shouts to close the door when the SCP enters.
21:51: SCP-X-2 follows Unit 2 to kitchen and Unit 3 slams door behind it. Unit 5 begins attempting to help Units 4 and 6 while Capt. ████████ begins calling for backup when a loud explosion causes the door to be blasted off its hinges. It was later found that the likely cause of the explosion was Unit 2 placing an incendiary grenade inside the gas oven in the kitchen, causing a gas explosion.
21:52: A burning SCP-X-2 runs out of kitchen yelping, but one of its legs has been blasted off in the explosion and it is severely injured. It leaves the house, but collapses after 30 metres.
21:53: House begins to shake due to massive damage from the explosion; MTF Team leaves house, dragging the unconscious Units 4 and 6 with them. Units 3 and 5 return to house to rescue any living family members, a █-year-old girl being the only survivor.
21:57: Fire department and paramedics arrive at house. During attempts to extinguish the fire, the house collapses. The surviving girl and Units 4 and 6 are treated at the scene; Unit 6 is pronounced dead from blunt force trauma to the skull. The girl and Unit 4 are airlifted to hospital.
22:04: Capt. ████████ and Units 3 and 5 work with Foundation Requisition agents to detain SCP-X-2 in a steel container, which is airlifted to Site-245 to be studied. Foundation helicopter also administers aerosol Class-A Amnestic to paramedics and firefighters to prevent information breach.
Aftermath: 6 casualties occurred as a result of the event: MTF Units 2 and 6, and George, Amelia and David █████, the father, mother and teenage son of the █████ family. The family's pet dog was also killed. The survivor, ██████ █████ (cannot be named to protect identity), a █-year-old girl, was administered Class-F Amnestic and given a new identity as an orphan; records were changed and added to systems to reflect this new identity. The incident was covered up as a gas leak and subsequent explosion in local and national news.
Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-X is kept within a secure safe at Site-25. Under no circumstances should SCP-X be brought within 100 metres of objects, locations or persons that willingly or involuntarily alter standard temporal flow (e.x. SCP-196[NEED PERMISSION], see Addendum SCP-X-Alpha).
Description: SCP-X-1 is a small cylinder constructed of an unknown, seemingly indestructible metal. A peeling, worn sticker is attached to the side, reading "Got a temporal paradox? Call the Stabilizers!". On one end of the cylinder, a small red button labelled with another sticker reads "Manual Callout". The other end of the cylinder has a green switch labelled with yet another sticker labelled "Auto-detect temporal anomalies". This switch is jammed in the 'On' position, hence the 100 metre minimum distance requirement.
When the button is pressed, or the SCP is brought within 80 metres of a temporally anomalous person, place or object, 3 entities, designated SCP-X-2A, B and C, will spontaneously appear within 2 metres of SCP-X-1 and attempt to 'stabilize' the nearest temporal anomaly. SCP-X-2 instances are dressed in body armor made of an indestructible fabric material currently unknown to the Foundation, and are equipped with a weapon each, designated SCP-X-3A, B and C (more information can be found in Addendum SCP-X-Beta). If one is not detected within 80 metres, SCP-X-2A will locate the nearest intelligent being (organic or non-organic) and inquire as to the location of the closest temporal anomaly. It generally does so in a polite manner, though has been known to verbally abused beings that are non-compliant or ignorant about the location of the nearest temporal anomaly.
Once SCP-X-2A has established the location of a temporal anomaly, it will travel to it in an attempt to neutralize the anomaly. If the anomaly is human or a living entity, all 3 SCP-X-2 instances will immediately attack it as soon as they move within 20 metres of the object, ignoring walls and other life forms in the way. If the anomaly is an object, the SCP-X-2A will produce a small metal sphere from an unknown location, place it near the object, then press a button on the sphere's surface, causing the object, the sphere and all instances of SCP-X-2 and SCP-X-3, as well as anything the SCP-X-2 instances were carrying. If the anomaly is tied to a location, SCP-X-2A will produce 4 spheres,
