SCP-XXXX-1 in containment.
Item #: SCP-XXXX
Object Class: Keter Euclid
Special Containment Procedures: SCP-XXXX-1 is to be kept in a tightly sealed 3.5-centimetre thick Teflon-Hastelloy atomically woven box approximately one foot in length and must only be removed under highly regulated testing procedures verified by Higher Level 3 research and security personnel or above. The box is to be cleaned of all traces of nitric acid coming from SCP-XXXX-1 through the use of a high-pressure sodium-hypochlorite and distilled water cleaning hose once per 7-day weekly cycle. During this procedure, SCP-XXXX-1 can be kept inside the box during cleaning or if needed, removed to another identical containment area during the purification process. If SCP-XXXX-1 is removed for testing or otherwise, all on-site staff near the specimen must wear full splash-protective Hazmat suits during testing and at least a level three full-face respirator and no direct skin exposure to SCP-XXXX-1 should be present at any time. After testing all implements used must be either destroyed or sterilised.
SCP-XXXX-1 is relatively harmless, however, if it happens to find and successfully attach to a human host, all available security personnel must be deployed to neutralize the newly created SCP-XXXX-2 subject through of the detachment of SCP-XXXX-1. All security personnel stationed at Site-██ must be extensively briefed on the XXXX-2 Neutralization Protocol and are to be equipped with all required gear for the task. In the case of a containment breach of SCP-XXXX-2, all required Mobile Task Forces must be promptly deployed to detain and neutralize the subject. After the neutralization of SCP-XXXX-1, SCP-XXXX-1 must be transported back to its containment chamber and remnants of SCP-XXXX-2 either destroyed or transported to a secure location for analysis or testing. If the containment site of SCP-XXXX is to be moved it is necessary to relocate the specimen another site similar and to Site-██ in which that it is in a highly remote geological location, away from any human settlements. During relocation, SCP-XXXX-1 must be kept inside of its Teflon-Hastelloy secure box and no human contact must be permitted until it is secured into its newfound containment chamber.
Description: SCP-XXXX-1 resembles a proboscisless leech almost indistinguishable from the species Philobdella gracilis. SCP-XXXX-1 normally remains relatively inactive until it senses a suitable host, similar to the doings of typical leeches. SCP-XXXX-1 seems to only react to human subjects and when in the vicinity it latches itself onto the chosen hosts body, causing it to become an instance of SCP-XXXX-2. In all testing of SCP-XXXX-1, the specimen appears to be inherently normal although through unexplained anomalous means SCP-XXXX-1 is seemingly invulnerable, with any attempts to destroy the specimen - whether it is through high exposure to extreme temperatures, blunt force, attempted incisions, etcetera - heeding no results. SCP-XXXX-1 is also found to secrete high concentrations of nitric acid along with its standard salivation at a heightened rate in comparison to leeches of similar type. Because of this much precaution must be kept in the containment of the specimen and any further testing must be conducted under strict regulation.
If SCP-XXXX-1 is to find a suitable host and attach to its bare skin it will cause it to undergo a form of anomalous mutation, creating an instance of SCP-XXXX-2. While in this state SCP-XXXX-1 remains firmly latched onto the body of the subject, although not impossible, it is highly difficult to separate SCP-XXXX-1 from an instance of SCP-XXXX-2 once bonding has occurred. Successful detachment has only been achieved twice through means of blunt cutting force by use of a sharpened wood-cutting axe and concentrated laser exposure. It is inferred that the process of SCP-XXXX-1 bonding with a host is what directly causes the anomalous properties of SCP-XXXX-2
Throughout all observations, the anomalous properties of SCP-XXXX-2 have seemed to stay the same. Once SCP-XXXX-1 has attached to a human subject the subject will then go through transmutation into SCP-XXXX-2. The growth rate of its keratin will increase greatly. Causing talon-like nails and accelerated hair growth - especially on facial regions, - etcetera. SCP-XXXX-2 also inherits many of the anomalous properties of SCP-XXXX-1, these have found to be the salivation of nitric acid as well as salivation to a much greater extent as well as the seeming invulnerability. SCP-XXXX-2 can only be neutralized by fully removing SCP-XXXX-1 from its body. Multiple PET scans on SCP-XXXX-2 has shown indistinguishably high amounts of brain activity, where seemingly all parts of the brain are fully active at all times. If SCP-XXXX-1 is removed from SCP-XXXX-2 the host becomes instantly brain-dead and all bodily functions stop instantly. When an instance of SCP-XXXX-2 is created the subject undergoes several muscle spasms lasting approximately anywhere from 40 seconds to 11 minutes, during which the subject will adopt an extremely hunched spinal posture and the extended nail growth and salivation are clearly observable. The time taken to create an SCP-XXXX-2 instance does not seem to affect any functions of the specimen and no reason is known to the varying time taken during transformation. SCP-XXXX-2 prefers to travel on all fours reminiscent of the quadrupedal travel of some species of apes but will adopt a bipedal stance of it is so required.
Once the transformation is complete the newly created instance of SCP-XXXX-2 will begin actively searching for the nearest Doritos packet. If SCP-XXXX-2 is kept in containment the entity will attempt to escape at all costs to locate and consume the nearest Doritos packet. SCP-XXXX-2 does not seem to distinguish from different flavours although subjects seem to prefer said Doritos with a mixture of traditional style Mexican salsa. SCP-XXXX-2 supposedly can smell out the closest Doritos packet with no limitations on distance or whereabouts of said packet. As well as this, SCP-XXXX-2 carries certain properties that causes any entity in possession of a bag of Doritos and/or Mexican salsa or near the subject in an approximate 1-kilometer radius of SCP-XXXX-2 to ‘hear’ the instrumental to the popular Spanish folk song ‘La Cucaracha’, with the closer a subject is to SCP-XXXX-1 resulting in the song becoming louder within the mind of a subject. However, any audio recordings taken in the area does not show any signs of the song, except the reactions of the subjects hearing the sound. If a subject is to ‘hear’ the song they will grow uneasy and gain the peculiar notion that ‘something bad is about to happen’. Apart from this, there is seemingly no substantial impact upon an entity that hears the SCP-XXXX-2 generated song.
All attempts to withhold sensed Doritos have resulted in catastrophic failure due to SCP-XXXX-2’s other anomalous properties. Once SCP-XXXX-2 has located and obtained the Doritos packet it will begin to savagely consume the substances until no noticeable food remains are left. After digestion SCP-XXXX-2 will continue to actively search out its next meal. As well as these anomalous behaviours after transformation, SCP-XXXX-2 will attempt to obtain as much clothing as possible, supposedly to cover the exposed SCP-XXXX-1 type symbiote. Peculiarly SCP-XXXX-2 will again prefer to wear traditional Mexican attire and has been seen on multiple occasions wearing a Mexican style Baja jacket and sombrero.
Addendum XXXX-1.1:
The following addendum lists multiple attempts to damage SCP-XXXX-1 and their results:
| Damage Attempts |
Results |
| SCP-XXXX-1 was exposed to a continuous stream of lit oxyacetylene gas for approximately 10 minutes. |
Flames continued to flare because of the flammable aloids secreted by the SCP-XXXX-1. No visible damage to SCP-XXXX-1’s outer skin layer. |
| SCP-XXXX-1 was exposed to tightly sealed near absolute zero temperatures for approximately 15 minutes. |
A thick layer of frozen liquid formed around SCP-XXXX-1 as a result of the excreted liquids from SCP-XXXX-1. This result may indicate nothing or it may indicate a cocoon being subconsciously formed around SCP-XXXX-1 to keep it alive. This may show a greater understanding of temperatures that we cannot begin to fathom. |
| Attempts were made to cut open SCP-XXXX-1 with surgical-grade incision equipment. |
Equipment was able to cut partway into the dermis of the skin of SCP-XXXX-1. Showing that highly specialised sharp equipment can penetrate the outer tissue of SCP-XXX-1. However, anything deeper seems to have anomalous properties unlike any other organism and are a different harder concentration of cells compared to outer tissue of SCP-XXXX-1. However, shortly after the small incisions were made into SCP-XXXX-1 the layers of skin healed over, leaving no trace of any skin lacerations. |
| SCP-XXXX-1 was forcefully stabbed using a highly sharpened standard utility hunting knife. |
Contrary to what would be assumed after the previous test the knife was unable to make any incisions into the body of SCP-XXXX-1. This perhaps shows that only very small, regulated incisions can be made in SCP-XXXX-2. |
| A 10-kilogram and 100-kilogram cast iron weight were dropped on SCP-XXXX-1 from a height of 5.1 meters, allowing it to reach an impact speed of 10m/s. |
Slow-motion camera footage of the events shows the force of the cast iron weight being absorbed by SCP-XXXX-1 and being reflected in an elastic effect. The force that was repelled by SCP-XXXX-1 was greatly negated to an estimate of approximately ⅓ the original force. |
| SCP-XXXX-1 was shot 3 times with both a 9mm pistol and 7.62mm rifle rounds at 1-second intervals. |
Small indentations were made at the impact sites of each bullet, these indentations quickly healed over, slow-motion replay shows small cuts on the skin where the 9mm pistol rounds were shot. |
| SCP-XXXX-1 was shot using a singular .50 calibre heavy sniper round. |
The force of the bullet impact caused SCP-XXXX-1 to skid across the testing area, slow-motion footage show SCP-XXXX-1 to compress and ripple reminiscent to what slow-motion footage of a human cheek being punched would show. No visible long-lasting damage was observed. |
| SCP-XXXX-1 was laid under continuous 7.62mm rifle round the fire for approximately 2.5 minutes. |
SCP-XXXX-1 sustained fire with seemingly to reaction or effects - apart from slight indentations - for roughly 2.2 minutes until the direction of the rifle fire was changed to shooting the lower part of SCP-XXXX-1, where the fire knocked the specimen across the room, scattering multitudes of SCP-XXXX-1 salivate, 2 researchers sustained mild burns as a result and testing was stopped. |
Note: It is assumed that all attempts to damage SCP-XXXX-1 and their effects transfer over to SCP-XXXX-2. That is, if the same method is carried out on SCP-XXXX-2 the consequent results will be the same.
Addendum XXXX-2.1
The following details the events that took place once Foundation personnel first became aware and came in contact with SCP-XXXX-2. At this time, the existence of SCP-XXXX-1 was unknown and SCP-XXXX-2 was documented as class Keter, simply under the guise of SCP-XXXX:
SCP-XXXX-2 was originally located by the Foundation in the Vietnamese summer of 197█ close to a ravaged local village near ███ ███, Vietnam. At this point, the subject was found wearing a highly ripped and tattered US OG-107 Type III basic military utility uniform exposing a black mankini. Facial scans of the original human host of said SCP-XXXX-2 instance show the subject to be Juan José, A Mexican-American cocaine dealer who was enlisted to fight in the Vietnam War on behalf of the United States Armed Forces. The village was left in ruins after SCP-XXXX-2 decimated the local area, supposedly searching for required Doritos. After coming in contact with the village, MTF Epsilon-6 ("Village Idiots") was deployed and after searching the local area the total death count was tolled to 83 casualties, with no survivors. As was later discovered this is not normal behaviour for an SCP-XXXX-2 instance but it is assumed that prolonged withdrawal from Doritos and/or Mexican salsa will cause SCP-XXXX-2 to go into a blood frenzy, destroying anything in its wake until it finds what it needs. The reason why SCP-XXXX-2 so desperately require these substances are unknown. After further searching, MTF Epsilon-6 came in contact with SCP-XXXX-2 where the hostile anomalous entity was only neutralized by the use of 5.4 milligrams of carfentanil (more commonly known as elephant tranquillizer) shot to the lower jugular. Three Epsilon-6 personnel sustained life-threatening wounds after the encounter but there were no resulted casualties. After neutralization, the subject was transported in a barred stainless steel cage towards Foundation Site-██.
5 hours into transportation SCP-XXXX-2 regained consciousness and managed to escape its cage by burning through the lock of its steel cage with its saliva. All available personnel were sent out to re-capture SCP-XXXX-2, who was found 1.2 hours later crouching on all fours over a deceased male carcass, savagely eating from a ripped bag of Doritos on the floor beside. Medical reports of the SCP-XXXX-2 victim show multiple deep cuts in the abdomen, revealing a sliced open stomach and liver as well as a mangled and cut esophagus, multiple broken bones and internal bruising of the deltoid. Analysis of the victim shows the subject died from blood loss approximately 41 minutes after it was found by Foundation personnel. SCP-XXXX-2 was found ravaging the stock of a nearby local convenience store when Foundation personnel intercepted the subject. After strenuous neutralization attempts, it was discovered that there was a large, leechlike organism attached to SCP-XXXX-2’s upper back. This, of course, was what would be later known as SCP-XXXX-1. SCP-XXXX-1 was detached from SCP-XXXX-2 by the use of a large cutting axe, swung full force by Foundation personnel. As this affair took place at approximately 2.3 hours past midnight no amnestics were needed and a cover story involving burst gas lines was spread throughout the general local area.
After neutralization, SCP-XXXX-1 was taken to Foundation Site-██ where containment and testing procedures began and SCP-XXXX-1 was deemed class Euclid.
Addendum XXXX-2.2:
The following is the listed XXXX-2 Neutralization Protocol that should be acted out if an instance of SCP-XXXX-2 is to be created:
All XXXX Security Personnel must be equipped with a personal tranquillizer gun and at least 1 full cartridge of .50 calibre ballistic carfentanil tranquilizer darts, in addition, personnel must wear full kevlar outer armaments over JSLIST chemical protective clothing. Other ordnance includes but is not limited to an M45A1 CQB Pistol and an M16A3 rifle coupled with an M26 Modular Accessory Shotgun, a standard 20-inch tactical Downrange Tomahawk and an M11 System Ordinance knife. Any XXXX Specialised Neutralisation Personnel must be also equipped with a precision laser burner, an X2 standard-issue taser and where needed an M9 model flamethrower as well as any of the aforementioned ordinance as required.
If an instance of SCP-XXXX-2 is to be created for testing purposes, all on-site XXXX Security and Research Personnel must be alerted to the fact a minimum of 48 hours before testing is begun. While an SCP-XXXX-2 instance is still active there must be at least 4 security personnel accompanying the current researchers in SCP-XXXX’s containment viewing and research area. In addition, at least 8 more security personally must be stationed in regular positions surrounding the outside of SCP-XXXX’s containment chamber. There must be a minimum of 4 trained XXXX Security Personnel and 1 active medical trauma specialist in every available sector of SCP-XXXX’s containment site. Unless testing requires it; SCP-XXXX-2 must be fed a constant supply of Doritos while active, SCP-XXXX-2 must be kept under watch to confirm that it is occupied with eating to keep SCP-XXXX-2 ‘sedated’.
Under the rare circumstance that SCP-XXXX-2 is to escape containment immediate action must be taken to ensure it does not escape its containment site or the surrounding areas. All needed XXXX Security Personnel must be deployed to recapture and neutralise SCP-XXXX-2 and if required any necessary Mobile Task Forces must be at hand and ready for deployment. To neutralise SCP-XXXX-2 careful action must be taken to promptly neutralise the specimen, ideally, any clothing the SCP-XXXX-2 instance is currently wearing is to be removed via the use of flame throwers or other ordinance to expose SCP-XXXX-1 on the host’s body. Then any means available must be taken to precisely remove SCP-XXXX-1 from the SCP-XXXX-2 instance. Preferably and through the use of a precision laser burner or a sharp ordinance while the specimen is subdued. The neutralisation of SCP-XXXX-2 is a highly dangerous process and precautions must be taken to minimize staff casualties or injuries. Once neutralised, SCP-XXXX-1 must be immediately taken back to its containment chamber and the previous SCP-XXXX-2 host is to be disposed of.
Addendum XXXX-2.3:
The following is an excerpt taken from the site research notes of Doctor ███████, former senior researcher for SCP-XXXX.
██/██/███3: The last test has lead to me to believe that there must be some sort of link between SCP-XXXX-2’s irregular amounts of high brain activity and the specimens constant need to obtain and consume Doritos and Mexican salsa. My initial thoughts are that SCP-XXXX-2 requires a steady supply of glucose and carbohydrates in order to maintain it’s high brain activity, but then again, why specifically Doritos and salsa and not any other foods, there are many more suitable foods one can consume to get the needed nutrients. I must properly field test my theory more.
Addendum XXXX-2.4:
After multiple denied requests permission to allow D-Class Foundation personnel to transform into an SCP-XXXX-2 instance and be withheld of any usual foods was accepted under strict security basis:
