SCP-504

Item #: SCP-504
Object Class: Safe
Special Containment Procedures: All seeds, plants, fruit, crossbreeds, and other products of SCP-504 are to be classified as SCP-504. SCP-504 seeds need no special containment, other than to prevent misuse by unauthorized personnel. Grown SCP-504 plants and their fruit should be kept in soundproof rooms. Guards and researchers assigned to maturing or growing SCP-504 are to be equipped with radio-enabled masks which insulate non-transmitted sound, and are to be instructed to avoid attempts at humor.
Description: SCP-504 is a species of tomato physically and genetically identical to that of the typical commercially-grown tomato. It was recovered in [REDACTED], Kentucky after a woman reported to the police that her farmer husband had been "murdered by his lunch". The Foundation is currently working to identify and destroy loose strains of SCP-504 in the surrounding commercial farming areas.
When a poor attempt at humor is made verbally within human hearing range of SCP-504's tomatoes, they instantly accelerate to a speed of at least 100 miles per hour (approx. 160 kilometers per hour, 45 meters per second) in the direction of the sound's source. Only mature tomatoes, separated from their vines and less than 10% rotted or chemically compromised, exhibit this effect once each. Tomatoes do not have to be physically intact, though ingested tomatoes are usually insulated enough from sound to prevent their effects before neutralization by stomach acid.
SCP-504 tomatoes seem to reach speeds relative to the inciting attempt at humor (see experiment log). Relevant variables seem to include corniness, humor-to-length ratio, and use of puns. Language appears irrelevant.
Note: Whoever snuck SCP-504 into the cafeteria kitchen is getting terminated. Those tomato slices are like fucking shurikens. - Dr. Blast

Item #: SCP-505
Object Class: Keter
Special Containment Procedures: SCP-505 is contained in a 50 m x 40 m x 10 m room at Site-██. SCP-505's containment area is to be sealed other than one secure airlock and a series of pipes allowing transport of SCP-505-1 to storage tanks in the event of SCP-505-1 reaching levels in which it poses a danger to containment. Sprayers for 4 M NaOH are to be available through SCP-505's containment area and the rest of Site-██ to combat a containment breach. In the event of a spill of SCP-505-1, the affected area should immediately be covered with an absorbent material (commercial blotting paper is currently standard for this purpose) and doused with alcohol or acetone if NaOH is not immediately available. NaOH immersion is the method of choice for SCP-505-1 containment, followed by incineration of affected material if practicable.
There are currently ██ instances of SCP-505-1 points of secondary contamination outside SCP-505's primary containment area. Containment in these areas is variable but efforts have been made to make procedures as similar to those of the primary site if possible. Of these secondary contamination zones, █ are unable to be fully contained at this time resulting in the spread of SCP-505-1 throughout the environment. These sites are to be monitored at all times and countermeasure development is of the highest priority. For a complete list of SCP-505-1 secondary containment sites, see Document 505-14A-███.
Description: SCP-505 is a Model ████ Faber-Castell fountain pen, produced in 2001. For documentation of its acquisition by the Foundation, see Addendum 505-2. It is identical in all respects to a standard fountain pen apart from its association with SCP-505-1. SCP-505-1 is the black ink produced by SCP-505, which exhibits the property of self-replication. SCP-505-1 spreads at a variable rate, affected by the substance it comes into contact with and the amount of SCP-505-1 present. Quantities of SCP-505-1 have been shown to increase at rates between 0.5 and 540 mL per second. Standard ink-removing chemicals are able to partially remove SCP-505-1 and inhibit its spread; however, sodium hydroxide is necessary to remove SCP-505-1 contamination completely, and has shown to be ineffective in environments with particularly high SCP-505-1 concentrations. Fortunately, the growth rate of SCP-505-1 appears to be inversely proportional to its quantity at high concentrations. Whilst the observed effects of this are negligible in most cases, this inverse growth phenomenon provides the only explanation for the partial containment of SCP-505-1 despite a number of cases of large-scale environmental contamination which were projected to otherwise lead to an NK-class end-of-the-world scenario.
Whilst SCP-505-1 exhibits no unusual properties other than its constant spread and partial resistance to removal, it nonetheless poses serious difficulties for control. SCP-505-1 will flow across non-absorbent surfaces and pass through porous surfaces in an identical fashion to normal ink. All liquid or solid objects or beings in contact with SCP-505-1 will be contaminated. SCP-505-1 will still adhere to non-porous surfaces such as metals, but newly produced SCP-505-1 will constantly flow off. Non-porous materials are thus catalysts for SCP-505-1 spread and all SCP-505-1 contamination should be covered in porous materials such as blotting paper for this reason. It is not possible to permanently contain SCP-505-1 in a non-porous container as said container's contents will gradually increase in quantity, leading to increased pressure and subsequent rupture. All containers being used to contain SCP-505-1 must therefore be drained periodically to prevent a containment breach.
SCP-505-1's effects on its environment are identical to those of an equivalent quantity of standard fountain pen ink. SCP-505-1 exposure will inevitably lead to the death of living organisms; plant matter will be killed due to inhibition of photosynthesis, whereas animals will be killed due to chemical poisoning. In humans and other mammals, SCP-505-1 contact will most likely be via the skin, where it will spread until it reaches an orifice or a break in the skin and subsequently enter the vascular system through mucous membranes. SCP-505-1 will spread through the vasculature and have catastrophic effects on all organ systems it reaches, as it continuously replicates and is unable to be excreted by the urinary system. Cause of death is generally multiple organ failure, although in most cases affected individuals will be terminated and decontaminated prior to this. For containment procedures in these instances, see Addendum 505-1.
SCP-505-1 also has an increased rate of spread through non-viscous fluids such as water, as would be expected of normal ink. Any contamination of the water table with SCP-505-1 must be prevented at all costs, due to the potential for an NK-class end-of-the-world scenario. It is unknown whether SCP-505-1's aforementioned property of an inversely proportional rate of spread will manifest in fluids, as experimentation with such high quantities of SCP-505-1 is strictly forbidden. Thus, any environmental SCP-505-1 contamination in water sources must be met with immediate damming and drainage into storage tanks of all affected areas.
Addendum 505-1: Procedures for dealing with SCP-505-1 contamination in humans
Administration of multiple-dose activated charcoal has been shown to slow the progress of SCP-505-1 contamination in humans but is unable to halt the process. The only known methods of treatment for SCP-505-1 contamination in humans are by immediate excision of the affected area or continuous application of ethanol to an affected skin region. Topical ethanol treatment will not prevent the affected individual from transmitting SCP-505-1 to other surfaces and is thus highly discouraged except in the cases of essential personnel, in which case containment procedures must be observed as in all other sites of secondary SCP-505-1 contamination. In theory excision or amputation of affected areas would be the gold standard for treatment but contamination of surgical instruments and personnel remains a problem. Therefore, all cases of SCP-505-1 contamination in humans other than essential personnel should be dealt with by termination followed by standard procedure of 4 M NaOH immersion and incineration of the remains.
Addendum 505-2: SCP-505 retrieval history
SCP-505 was acquired by the Foundation from the town of ██████ in Oman, when the town in question was quarantined by the Omani government due to reports of a black fluid beginning to seep out from the town's post office and causing the deaths of a number of its inhabitants. Fortuitously the arid and remote location of the incident prevented wide-scale environmental contamination of SCP-505-1. The Foundation retrieved SCP-505-1 with ██ casualties. No other anomalous properties of the town's post office or the town itself were detected. It was deemed necessary to terminate ████ civilian inhabitants of ██████ who were deemed likely to be contaminated. The incident was reported as a non-extranormal chemical spill.

Item #: SCP-506
Object Class: Safe
Special Containment Procedures: SCP-506 grows in a 3 m x 3 m patch of soil, kept watered and fertilized via an automatic system. The air of the room where SCP-506 is kept must be filtered to prevent release of SCP-506 seeds into the environment. Personnel entering the enclosure must wear biohazard suits composed of inorganic material, and must be decontaminated upon leaving the area.
Due to the potential dangers associated with cross-contamination, SCP-506 and SCP-124 are not to be stored at the same Foundation site under any circumstances.
Description: SCP-506 is a genetically engineered variant of zucchini (Cucurbita pepo) created by the ████████ Corporation as a hardy and rapid-growing food plant. SCP-506 exhibits several undesirable and dangerous qualities:
(1) SCP-506 will attempt to grow on any organic material, including on living beings. The seeds germinate on contact.
(2) SCP-506 grows extremely rapidly, reaching full size in five minutes or less.
(3) Due to its rapid growth, SCP-506 drains its growing medium of nutrients at an accelerated rate. Nothing will grow in soil that has harbored SCP-506 plants without extensive nutrient replacement.
(4) SCP-506 seeds are much smaller than typical squash seeds, and disperse easily in the wind.
SCP-506 is inedible, as the seeds will [DATA EXPUNGED] if any are consumed. To the best of the knowledge of The Foundation, SCP-506 has not escaped into the wild, and ████████ Corporation has destroyed all samples in their possession.

(Note: Labeled as a time lapse in case of accidental public release.)
Addendum: SCP-506 is evolving rapidly, as indicated by the incidents below.
[Incident Report 506-1 5/16/20██]
SCP-506 plants observed attempting to grow on the walls of the containment facility. Although the plants died of malnutrition, testing indicates the latest generation requires 35% fewer nutrients than when originally contained. Research in progress to find materials that do not support SCP-506 growth.
[Incident Report 506-2 9/1/20██]
Dr. K██████ found dead in the SCP-506 enclosure, covered with plant growth. The means by which his suit was compromised is unknown. SCP-506 roots have been found to secrete a powerful anesthetic, explaining why Dr. K██████ did not sound the alarm or attempt to escape the area.
Researchers must be under video surveillance while working with SCP-506, with another researcher ready to assist in case of accidental infestation. Reclassification as Euclid recommended.

« SCP-505 | SCP-506 | SCP-507 »


Item#: SCP-507
Object Class: Safe
Special Containment Procedures: SCP-507 is allowed free roam of the facility, obviously barring anything that would breach security or safety protocols. Any time SCP-507 leaves its private quarters it must be accompanied by an agent, mostly at this point to make sure that it does not “shift” without the facility's knowledge. SCP-507 should not be physically touched if there have been more than two weeks since its last “shift”; the risks inherent in disobeying this protocol make the action its own punishment, should the issue of disciplinary measures ever come up.
When SCP-507 undergoes a shift, faculty will be informed to keep an eye out for its eventual reappearance. It also has a tracking device implanted into it, and a daily signal check should verify whether or not SCP-507 has returned from its trip. If it reappears in or nearby the facility, SCP-507 will return to its quarters on its own; otherwise, a retrieval team of three plainclothes agents may be sent to provide transportation back. Upon successful return, SCP-507 can be the subject of various physical tests up until two weeks after each shift.
It is worth noting that SCP-507 is allowed a computer with an Internet connection (via a proxy which strictly limits what information can be uploaded, and to where) in its room, and may petition to use/meet with/act as a test subject for Safe or Euclid SCPs that do not affect mental functions negatively or carry an infectious trait. This is a result of SCP-507's persistently clean record, and the implication that if SCP-507 was ever going to be a security leak it would have used its faux-teleportation powers to do so already. It is also worth considering that SCP-507 is actually below-average in most physical traits, and that in even worst case scenarios any SCP agent should be more than capable of carrying out a termination order.
Description: SCP-507 is a Caucasian male with blond hair and green eyes, sporting no other outstanding characteristics besides being somewhat overweight and speaking with a vague accent of disputable origin. Although SCP-507 has an already-established name due to its unremarkable upbringing, it seems to find entertainment in forcing those it meets to give it a nickname in lieu of divulging this information. Thus SCP-507 will now respond to the names Tommy, Steve, Bruto, Guy, Houdini, and Grabnok the Destroyer.
SCP-507 was originally recovered from the ████ ██ asylum, when standard surveillance following repeated successful escape attempts brought its abilities to light. All records of this incident were confiscated, and SCP-507 was taken into custody under the pretense of moving it to a more secure facility.
The original theory was that SCP-507 possessed some form of teleportation ability, as it would suddenly disappear and eventually reappear in a different location. Subsequent interviews with the subject did verify that its ability could be used in such a manner, but that it was merely a side effect for its main affliction. SCP-507 holds that during its periods of “disappearance” it is actually displaced into a random alternate reality; the landscape generally stays the same, but the inhabitants and climate of the parallel world often do not. SCP-507 also insists that it has no control over the time and duration of these shifts; this has more-or-less been confirmed by the subject being known to “displace” at inconvenient times such as mid-sentence, while sleeping, or even while using on-site public facilities. If SCP-507 moves about in the alternate world, the eventual shift back will then place it at the corresponding area in our reality. A sample list of SCP-507s descriptions of alternate realities can be found in Document 507-00.
Mentally, SCP-507 shows no large deviations from the psychological profile for a normal person. It has confessed to have always had a great interest in the paranormal and mythological, which has directly led to its eventual permission to interact with relatively harmless SCPs. SCP-507 especially enjoys meeting with other sentient SCPs, once going so far as to request a small “vacation” to visit SCP-082. The request was eventually granted after persistent pleading from SCP-507, and the meeting was thankfully uneventful.
Document #507-00: A sample list of SCP-507s supposed extradimensional travels, along with any demands made by it after returning.
Subject arrived in complete darkness, leading it to assume that the current location was indoors or subterranean. After fumbling about for a possible way out, subject heard a sound akin to muted breathing nearby. Subject then decided to curl up in the nearest corner and “wait it out” instead of risking a blind confrontation with an unknown creature.

Request: A standard flashlight, which it now always carries on its person.

Subject appeared in a replica of the facility, although apparently fallen into disuse. Further exploration led to the discovery of various corpses strewn about the area, all heavily decayed and covered in an odd type of mold. Upon noting that the “corpses” seemed to rhythmically expand and contract as if still breathing, subject attempted to leave the facility. This idea was quickly discarded when it opened an exit and found that the outside world was apparently coated with the same odd growth.

Request: Heavy doses of voriconazole, and a fungal expert to help ascertain the nature of the mold. No exact match of the described mold was found, but it was noted to share many attributes with certain types of Cordyceps Fungi. [See Addendum 507-02]

Upon reappearing, subject was reported to mutter “So many spiders.” Subject refused to elaborate.

Request: A handheld firearm of any type. Request was granted under the stipulation that said firearm is specifically built to only use rubber bullets.

Subject once again appeared in a pitch black location with breathing nearby. Upon turning on its flashlight, subject was surprised by a man wearing a black business suit and sunglasses, with an impossibly wide smile. Said “Smiling Man” was apparently leaning in toward SCP-507 when it turned on the light, the end result being that their faces were almost touching. Smiling Man then remarked “Back so soon?” before subject switched the light off again, discharged all the rounds in its firearm at the general vicinity of the man, and once more curled up into the nearest corner until shifted back into our reality.

Request: None.

Those with Level 2 Security Clearance may read a full list by accessing document #507-3B
Those with Level 2/507 Security Clearance should also see Interview 507-G for evidence of a particularly noteworthy shift.
Addendum 507-00: Agent ████ went missing on [EXPUNGED] at the same time as SCP-507. A full scale search was launched to find either of them, only for SCP-507 to appear a week later. When questioned, it said that ████ was holding onto its shoulder when it shifted, leading to both of them to appear in an alternate dimension where [EXPUNGED]. During the ensuing chaos, SCP-507 lost contact with ████ and could not relocate him before it shifted back into “standard” reality. A new protocol has been placed in light of this - no one is to come in physical contact with SCP-507 after two weeks following a displacement. Reevaluation of previous incidents has shown that there have always been at least two weeks between each, so this timeframe will be the only “safe” time to touch SCP-507 until further notice.
Addendum 507-01: I don't care how much he grumbles about it; SCP-507 is not to be cleared for challenging SCP-076-2 to fifty rounds of Tic-Tac-Toe. Just… no. -Dr.███
Addendum 507-02: Fungus encountered by SCP-507 seems similar to that resulting from experimentation with SCP-407.

Sub-critical Portion of SCP-508

Item #: SCP-508
Object Class: Safe
Special Containment Procedures: SCP-508 requires no special containment procedures so long as it is kept out of direct view of any SCP staff. At least ██% of SCP-508 must remain covered except when actively being tested. It is currently kept in a small closet, with no windows or ventilation. The door is to be kept securely locked at all times.
If SCP-508 is to be tested, it may be sealed in an opaque container and transported to any environmentally-sealed testing room available. Due to the potential risk resulting from its secondary effect, the room is to be sealed using positive pressure and sanitized using ██████ when the test is complete. Unless there is a strong need to preserve the test subject, they, also, should be sanitized using ██████-██; in the event that the subject must be retained, they should be held in quarantine for a period of no less than ███ days.
Description: SCP-508 appears to be a 'Random Dot Stereo-gram' poster, of dimensions 255x197cm. Caution must be taken when interacting with it, as even a cursory glance may fascinate the viewer, giving them an overwhelming desire to properly view the 'hidden' image. Viewing the image appears to only be possible when the viewer stands 1 meter in front of the image, and stares directly at it; attempts to view the image via mirrors or having multiple subjects attempt to view it have failed, with only the properly positioned subject able to see the image.
In testing, achieving proper focus to be able to view the image has taken an average of 93 seconds. Subjects exposed multiple times appear to view it more quickly, but never in less than 60 seconds.
Once the viewer has achieved proper focus, the poster seems to function as a window to some other location (Effect 1.) These locations range from the banal (e.g., a view of the same room, but from the perspective of a different wall) to surreal and potentially maddening. (See ████-█.) In addition, the window appears to function bi-directionally, exposing the viewer to the gaze of whatever is being viewed.
Regardless of the time required for the viewer to acclimate to the needed focus for the image, after the same amount of time has passed with the user viewing through the window, the interface appears to undergo a secondary change (Effect 2), and becomes permeable, although only to the viewer and the viewed subject/area. (See event log: ██████, ██████, ██████-█ and ██████.) The requirement for viewing appears to extend to the secondary effect: even in the case of event ██████-██, where the subject was dismembered and pulled through the image, two other subjects in the test room were unaffected.
Addendum: Photographs, scans, and copies of SCP-508 do not inherit its primary properties, as the user is unable to see more than a strangely compelling blur. All such copies should be kept filed away, and no personnel shall view them for more than ███ minutes in any given ███-hour period, as extensive viewing has been shown to induce an overwhelming desire to see the original (Effect 3.)
If the subject is unable to see more than ██% of the image (due to it being partially covered, obscured, etc.) neither effect is demonstrated. Copies of SCP-508 show the same limitation with regards to Effect 3.
Addendum: Careful removal of the backing material revealed a price sticker, indicating SCP-508 was sold for $14.98. No indication of the store from which it was sold was found, nor was the UPC code able to be matched to any known database.
Test Logs:
Experiment-1: Male subject D-9211 was exposed to SCP-508 and told to make note of any image perceived. After 93 seconds, subject began to giggle. When asked to explain, subject blushed, and stated "Oh… Nothing… I just… Nothing, really. Just a funny view." Later interrogation revealed SCP-508 to have provided a view into a women's changing room at a local department store. Subject terminated ██/07/10 16:23 due to unreliability.
Experiment-2: Male subject D-4599 was placed in a chair in front of SCP-508 without instruction. The subject was seen to glance at SCP-508 momentarily, look around, then return to observing it with a perplexed expression on his face. After 102 seconds, subject appeared to enter a state of extreme agitation, sweating profusely and attempting to draw back from SCP-508, without leaving the chair. After an additional 102 seconds, subject suddenly became very pale and attempted to leave the chair. After moving less than 12 inches, subject screamed and collapsed to the floor. Examination of subject revealed an 11 cm cylindrical segment missing from the left side of the subject's abdomen. The edges of the wound appeared to be cauterized; autopsy revealed that death occurred due to severe systemic shock.
Experiment-3: Male subjects D-8788 and D-7422 placed in test chamber with SCP-508 and instructed that the first to identify the image would 'win a prize.' After several minutes of vying for position, the subjects both began to scrutinize the poster. After 87 seconds, D-7422 suddenly turned his head away in disgust. Inquiries as to what had become visible were not responded to, and subject was remotely terminated. D-8788 was advised to resume the test on pain of suffering the same disposal. After 92 seconds, D-8788 suddenly smiled, and moved closer to SCP-508, before tapping on its surface. Subject appeared surprised to find a solid surface, but continued to observe. After an additional 87 seconds the subject was seen to lift his head and sniff, then suddenly dive at SCP-508, passing through its surface with no resistance. Subject D-8788 has yet to be located.
Experiment-4: Male subject D-4431 and Female subject D-6744 placed in test chamber with SCP-508 after being shown footage of Experiment-2. Both subjects sat on the floor facing away from SCP-508 and began to talk. After several minutes D-6744 shook her head in response to a comment made by D-4431 and inadvertently allowed her gaze to rest upon SCP-508 for less than one second. Although visibly shaken, she looked back at it repeatedly for the next 10 seconds before changing position to obtain a better view. Repeated warnings from D-4431 failed to dissuade D-6744 from attempting to view the image. After 103 seconds, D-6744 suddenly blanched and began to vomit. Subjects were then removed and interrogated. Subject D-6744 was unable to describe what she had seen, stating that it was somehow 'wrong', but in a way she could not explain. Subject D-4431 admitted to looking at SCP-508 after seeing D-6744's response, but claimed to have seen nothing. Subjects quarantined for potential future testing.
Experiment-5: Female subject D-9801 instructed to enter test chamber, observe SCP-508, and report back. After 93 seconds of observation, the subject was heard to exclaim "Oh, that's neat!" Interrogation revealed subject to have seen an image of herself in what she thought was some kind of experimental mirror. Subject also noted that the image was not reversed from left to right, as would be the case in a conventional mirror. Subject quarantined to be used for future tests.
Experiment-6: Male subject D-6621 shown video of Experiment-5 and instructed to enter test chamber, observe SCP-508 and report back. After 97 seconds, subject D-6621 made sounds indicative of disgust and stated "Ewww! They can't make it in here, can they?" After an additional 97 seconds, D-6621 suddenly demanded to be let out, and moved to the farthest point in the test chamber from SCP-508. After 43 seconds of the subject becoming increasingly agitated and demanding to be let out, the subject suddenly began to scream and swat at his legs. Analysis of the video log shows that the subject's legs appeared to be being bitten by a large number of small creatures; based on concurrent wounds, at least 27 bites were being inflicted at any one time. After 14 seconds, the subject collapsed, whereupon the subject began taking wounds over his entire body. After an additional 14 seconds, the subject lost consciousness. Within seconds of the subject being rendered unconscious, all damage ceased. Subject was unable to be returned to consciousness, and was terminated ██/21/10 02:17. Autopsy revealed the bites to be consistent with those of unusually large bedbugs, with traces of a neurotoxin found within the wounds.
Experiment-7: Repeat female subject D-9801 instructed to enter test chamber, observe SCP-508 and report back. After 81 seconds of observation, the subject was seen to turn about several times and state "Oh, well, that's different." Interrogation revealed subject to have seen an image of herself as seen from behind. Upon turning around, subject saw what appeared to be an identical copy of SCP-508 behind her. No such object appears on the video log. Subject quarantined to be used for future repeat tests.
Experiment-8: Male subject D-2232 placed in test chamber and told that he would be 'rewarded' if he could properly identify the 'object' shown by SCP-508. Subject had been fitted with a remote-activation tranquilizer collar to test the effect loss of vision (through unconsciousness) would have on Effect 2. After 87 seconds, subject leaned forward and stated "Wow! I didn't know these could show live images! Who is that?" Subject was advised to continue observing. After an additional 87 seconds the subject made a 'come-here' gesture towards SCP-508. Six seconds later, video surveillance shows SCP-507 climbing out SCP-508's frame. 507 indicated appreciation at being 'retrieved' as his most recent shift had interrupted his lunch. SCP-507 was permitted to return to his normal routine. Subject D-2232 terminated due to security risk ██/29/10 04:27. Tranquilizer collar recovered for future testing.

Item #: SCP-509
Object Class: Safe
Special Containment Procedures: SCP-509-A and SCP-509-B are both to be contained on-site, due to their immobility. Each is to be cordoned off, and any members of the public turned away. Outside of research and maintenance purposes, no humans or pigs, living or dead, are to be allowed into either structure. Personnel may safely enter and leave SCP-509-A and SCP-509-B within four minutes of activation and while inactive.
After testing, any living humans recovered from SCP-509-B are to be trained as Level 0 personnel and assigned to minimal security positions. Personnel are cautioned that smoke inhalation from SCP-509-A poses a health hazard, and are advised to wear particulate respirators during and immediately after testing.
Description: SCP-509 is the collective term for two structures with similar and possibly linked anomalies. SCP-509-A is a wooden sauna located in Gaston, Oregon. When activated remotely, it functions as normal for an electric stove sauna, producing steam by dripping water onto a heated surface. Local records show that SCP-509-A was built in 1987, and exhibited no anomalous properties until shortly before its containment in 1995.
When used by a human, SCP-509-A produces clouds of smoke, instead of steam. Though the smoke is at this point nonanomalous, the means by which it is produced are unclear. After approximately six minutes of smoke production, SCP-509-A enters an active state, and tracking devices placed inside fail for the duration of its active period. Attempts to enter SCP-509-A no longer lead to its interior (See Experiment Log 509).
After a period of 155 minutes, SCP-509-A returns to its inactive state, now filled with extremely thick smoke. All humans in SCP-509-A at activation are no longer present within the structure, but are replaced by an equal number of cured pig carcasses. These carcasses exhibit no anomalous properties.
SCP-509-B is a brick smokehouse located near Hesdin in northern France exhibiting similar anomalous properties to SCP-509-A. SCP-509-B is believed to have been built circa 1750, though it too functioned normally until 1995.
Whenever one or more cleaned but uncured pig carcasses are placed into SCP-509-B, it ceases to produce smoke and instead produces steam. Six minutes after the addition of the last pig carcass, the interior of SCP-509-B becomes inaccessible in a similar manner to SCP-509-A. After twelve minutes, SCP-509-B returns to its inactive state.
Any pig carcasses present at time of activation are replaced by living humans. These humans speak fluent English, and claim to have just been at a sauna. Physical examination reveals no anomalous properties and dehydration consistent with approximately twenty minutes in a sauna. Under questioning, these individuals demonstrate functional knowledge within standard parameters, but have no recollection of life before recovery from SCP-509-B. No records have been found of persons recovered in this way.
Experiment Log 509:

Experiment 509-005:
Date: 9/21/1995
Head Researcher: Dr. Samuel Chou
Procedure: D-35475 was instructed to enter SCP-509-A fifteen minutes after activation. Subject reported that he was unable to open the door, and so was given tools to remove the door from its hinges. With assistance from research staff, D-35475 was able to remove the door. Instead of its interior, SCP-509-A contained an empty white room substantially larger than the exterior of SCP-509-A. D-35475 was ordered to enter SCP-509-A. On doing so, he reported that it contained a large quantity of pigs. When questioned regarding the incongruity of this with external observations, D-35475 clarified that he did not in fact see, hear, smell, or feel any pigs, but rather was certain of their presence.
Experiment 509-017:
Date: 4/04/1996
Head Researcher: Dr. Samuel Chou and Dr. Alexander Bejo
Procedure: SCP-509-A and SCP-509-B were simultaneously activated. Thirty minutes after activation, D-35475 and D-31161 were instructed to enter SCP-509-A and SCP-509-B, respectively. As expected, both reported seeing the white chamber. However, D-35475 did not perceive it as containing pigs, and D-31161 did not perceive it as containing humans. Each reported seeing a distant blurred figure, which matched the movements of the other, though certain identification was impossible. Attempts for each to move towards the other figure proved similarly ineffective.
Experiment 509-036:
Date: 1/20/1999
Head Researcher: Dr. Alexander Bejo
Procedure: D-35574 entered SCP-509-A while active, but unusually did not perceive the presence of pigs. D-35574 reported, and camera footage confirmed, a distant blurred figure, similar to those observed during concurrent testing of SCP-509-A and SCP-509-B, despite the fact that no testing was scheduled for SCP-509-B that day. The planned testing was aborted. After recovery from SCP-509-A, a routine medical exam revealed D-35574 to be infected with a virulent strain of dengue fever not matching any known variety.
Experiment 509-043:
Date: 3/8/1999
Head Researcher: Dr. Evan Green
Procedure: A live pig was placed into SCP-509-A, which was then activated. Rather than steam or smoke, SCP-509-A began to fill with aerosolized decontamination fluid. After six minutes, the interior became inaccessible for 40 minutes. On deactivation, the pig had been replaced by a deceased male human in a hazmat suit. The corpse exhibited severe burns across and through its entire body. The torso had been opened and emptied of all organs save the liver and heart. No unusual occurrences were reported at SCP-509-B.

« SCP-508 | SCP-509 | SCP-510 »


Item #: SCP-510
Object Class: Keter
Special Containment Procedures: Instances of SCP-510 are to be treated as a Level 1 infective substance, and are not to be handled by anyone not in contained-atmosphere Haz-Mat (CAHM) suits. Any staff interacting with SCP-510 must be monitored for one month after interaction. Infestation by SCP-510 will be met with immediate quarantine and sterilization of the surrounding area.
Containment units must have air-tight seals on any and all possible access points. Staff access is to be provided by a dual airlock, with chemical showers at each stage. Robotic surrogates are to be used whenever possible for SCP-510 interaction, and all materials interacting with SCP-510 are to be sterilized and quarantined for one month after interaction. Seals are to be checked and repaired weekly.
Any staff observed expressing elevated levels of fatigue, sleepiness, or exhaustion are to be quarantined and tested for infestation. In the event of multi-subject infestation, site-wide lockdown will be initiated.
Description: SCP-510 has thus far proven difficult to fully identify. It is possibly a form of microorganism or a form of “nanite”. The particles of SCP-510 appear to be surrounded by a field that causes a “blurring” effect even at high magnification. Tests have come back with wildly varying results, and samples have simultaneously exhibited properties of organic and non-organic matter, as well as properties of solids, liquids, and gasses. Current research views it as a form of mold or virus, due to its response to high heat and chemical sterilization.
SCP-510 infests soft surfaces such as fabric, feathers, hair, or foam, with the ability to remain dormant in such substances for years. If SCP-510 encounters delta waves, typically emitted by humans entering sleep, SCP-510 will “activate”, and begin to infest any nearby organic life. Infestation follows a set progression (See Addendum 84-B: Symptoms and Progression), most often ending with the “death” of infested subjects after 4 to 6 days.
SCP-510 appears to prefer mammalian life for infestation, primarily human beings. Attempts to artificially “infest” other life forms have met with very limited success. Possible applications of SCP-510 and its “life support” function are being researched. High heat and highly acidic chemicals have been able to "dissolve" SCP-510 particles. Dissolved particles leave behind no detectable residue.

Addendum: Document 84-B: Symptoms and Progression

Stage 1: Infestation
Symptoms: Exhaustion, fatigue, sleepiness, general listlessness, itchy eyes, general head pain.
Description: SCP-510 begins to form sting-like extrusions, which anchor into the skin. Extrusions continue to grow into the skin, contacting all major organs and systems in 8 to 24 hours. Subjects will grow progressively more tired during this time and will seek out quiet, dark areas in which to sleep.

Stage 2: Initial Manifestation.
Symptoms: Deep coma, “pillow” formation by SCP-510 on the body, progressive invasion of biological systems (nervous, cardiovascular, respiratory, etc.)
Description: SCP-510 forms large, pillow-like growths on the body. These growths are warm, and emit a soft light, with a texture described as “microfiber plush”. Subjects slip into a deep coma, becoming totally unresponsive to any and all outside stimuli. SCP-510 will start to “take over” biological systems, causing blood, neural activity, and even oxygen to pass through the growths before being returned to the subject. It has been observed that subjects in this stage enter a dream state more vivid than standard REM sleep.

Stage 3: Full Manifestation
Symptoms: Total dependence on SCP-510 for all biological functions. “Bonding” of the skin with SCP-510. Slow reduction in mental activity.
Description: SCP-510 takes full control of all biological functions for the host organism. Damage to the growths at this point will result in the immediate death of the host, as the growths are now performing all biological functions for the body. A form of “accelerated atrophy” sets in, with muscular and skeletal structures beginning to weaken and shrink, and total shut-down of most organs. Subjects are observed to lose 44% of their body mass during this stage. SCP-510 will directly bond to the skin, replacing the thin “threads” with larger protrusions of the growths. The brain begins to slow down and does not register any pain or awareness of these changes, showing high stimulation in areas with contentment and comfort.

Stage 4: Conversion
Symptoms: Rapid growth of SCP-510. Major reduction in host physical mass. Absorption of major organs and tissues by SCP-510. Host's brain enters the “Deep Dream” state.
Description: SCP-510 begins to compromise the basic structure of the body, “absorbing” organs, skin, bones, and muscles. Subject's mass will be reduced to 1/10th of initial size, with only a few tissues and the brain remaining. The brain enters a state labeled “Deep Dreaming”, in which brain activity is reduced to a point that a subject may be declared legally dead. However, brain activity continues, with evidence of some sense of surroundings being recorded. This is remarkable, considering most hosts at this stage are a brain, spinal cord, and a few clumps of tissue encased in SCP-510 growths.
Activity at this stage seems to be initially located in “comfort” and “contentment” centers, with activity shifting into “fear” and “alarm” centers as conversion continues. SCP-510 begins to break down into individual particles on the surface of the growths.

Stage 5: Resolution and “Sporing”
Symptoms: Absorption of remaining tissues. Breakdown of SCP-510 into individual particles.
Description: SCP-510 absorbs the remaining tissues, including the brain, over a period of 12 to 14 hours. Brain scans show highly elevated levels of activity, consistent with extreme fear or pain at this point, which slowly shift back into a more “relaxed” state as the brain is absorbed. After full absorption, SCP-510 will break down into individual particles, with a full break down of the growths after three hours. Particles will then float in the air, until making contact with a receptive surface.

Item #: SCP-511
Object Class: Euclid
Special Containment Procedures: When an instance of SCP-511 is identified, the affected residence shall be quarantined and will receive the next sequential site designation.
Excepting one main entrance, sites hosting SCP-511 will have all points of possible entry or exit permanently sealed with appropriate building materials. The main entrance will remain locked at all times. Entry is permitted to Foundation personnel with written authorization from Level 3 or higher. All SCP-511 sites will be equipped with remote monitoring equipment allowing for 24 hour surveillance and a continual tracking of the numbers of SCP-511-1 inhabiting the site.
At all times one (1) Class D personnel will be resident in the site. Personnel with this assignment are exempted from monthly termination for the duration of assignment. Candidates for this assignment shall be exclusively drawn from a population of post-menopausal women with a global Clinical Dementia Rating of 2 or greater. (Note: due to the exclusive nature of this population, O5-█ has approved recruiting from local hospice and/or nursing homes if necessary. Ref: Incident I-511-11)
The population of SCP-511-1 within a site must remain within an optimal range of 50 to ███ individuals. Below this range, adult Felis domesticus should be introduced to the site to increase population to minimum levels. If population exceeds ███ individuals, it must be culled immediately. Any SCP-511-1 found outside the containment site shall be euthanized and the remains incinerated.
Any biological material leaving the containment site for testing will be handled in accordance with standard protocols for a level 4 biohazard. All specimens are incinerated after testing is complete. Before coming in contact with any material from the containment site, personnel must be inoculated for Influenza, Hepatitis A, Hepatitis B, ████████ █, Tetanus, Tick-borne encephalitis, and ███████ ██████. Full medical workups are mandatory on a bi-weekly basis for personnel working with SCP-511.
Description: Instances of SCP-511 typically occur within residential structures with a block or stone foundation that includes a basement or crawlspace. All attempts to remove an instance of SCP-511 from such a residence have proved ineffective. (Ref: Interview 511-A)
SCP-511 is always found associated with a colony of feral Felis domesticus, common domestic cats. Members of this colony are designated SCP-511-1.
SCP-511 is a mass of biological matter taking the form of a large feline, often with extra limbs, eyes, mouths or other organs. It is typically coated with dirt, blood and fecal matter, making its fur appear black despite its actual coloring. (Tests have shown SCP-511's fur to actually be a random patchwork of various feline coat patterns, colors, and lengths.) SCP-511's mass varies from 10kg to over 50kg, roughly in proportion to the number of SCP-511-1 in the associated colony. The tissue that makes up this mass consists primarily of the bodies of deceased SCP-511-1. The portion of SCP-511 that does not comprise SCP-511-1 consists of other biomass; small rodents, various plant materials, insects and insect larvae, black mold, a human [DATA EXPUNGED]. Incorporation of dead tissue into SCP-511 does not appear to slow the normal process of decay. Different areas of SCP-511 undergo different stages of biodegradation at any given time; some areas show little more than lividity, while other areas may show active carrion insect infestation, and some areas may even show liquefaction of tissues. (Note: Researchers have described SCP-511 making a “purring” sound. Tests have shown this sound does not originate with SCP-511, but is actually the sound of insects, most often blowflies, trapped within its mass— Dr. A. ████)
SCP-511 prefers to inhabit dark spaces with a relatively high humidity, such as old basements and crawl spaces. It will continually scavenge its immediate area for new biomass to incorporate into itself, displacing and expelling matter that has decayed past mechanical usefulness.
Examples of SCP-511-1 resemble ordinary Felis domesticus that have undergone extreme neglect. They display a body condition score of 2 or 1, regardless of the amount of food available. Ulcerated skin is common, as are parasitic infestations, tumors, and various viral and bacterial infections. (SCP-511-1 are known carriers of a particularly virulent strain of ███████ ██████.) A typical SCP-511-1 shows no interest in grooming itself, and has patchy and matted fur. It is unclear to what extent the physical condition of an SCP-511-1 is a result of the influence of SCP-511, and to what extent it is due to sub-optimal living conditions.
Several observations have been made of an SCP-511-1 retrieving biomass from elsewhere and bringing it to SCP-511 to be incorporated.
Addendum 1: Incident report of containment breach at Site 511-█

+ Incident I-511-11

- Incident I-511-11

Document# I-511-11
Personnel involved: D-7856, male subject 35 years of age.
Date: 08/27/19██
Location: Site 511-█, ████ Evergreen Way, ██████████, California.
Description: After determining that a permanent human presence at a SCP-511 site results in moderation of aggression in SCP-511-1, containment protocol is updated to require class D personnel reside on-site in the event the original homeowner is deceased. Six months after this policy is established, D-7856 is assigned to Site 511-█. As expected, within a week, aggression levels of SCP-511-1 toward Foundation personnel lessen considerably.
Sixteen days after being assigned to Site-511-█, D-7856 begins showing signs of increased aggression; verbally abusing Foundation personnel and engaging in superficial vandalism of Site-511-█. D-7856 is reprimanded.
Eighteen days into his assignment, D-7856 interferes with a Foundation team by throwing garbage and yelling obscenities. D-7856 is subdued with a tranquilizer dart and locked in his quarters.
At twenty days, D-7856 begins capturing SCP-511-1 and [DATA EXPUNGED] is only discovered when a Foundation research team enters for routine specimen collection 48 hours later. The team discovers remains from 37 separate SCP-511-1 collected in the kitchen. Bodies are dismembered and show signs of [DATA EXPUNGED].
D-7856's body is discovered in the basement after an apparent attempt to [DATA EXPUNGED].
Site 511-█ is incinerated as an emergency containment procedure.
Ok, I think there's something to the “crazy cat lady” idea. Think we need to be more careful with the Class Ds on this one – Dr. A. ████

+ Interview 511-A

- Interview 511-A

Interview 511-A
Interviewed: Agent ████████
Interviewer: Dr. A. ████
Foreword: Agent ████████ was sole survivor from Mobile Task Force ████-█ assigned to retrieve an SCP-511 for study from Site 511-47 after the death of the homeowner, Mrs. B. ████████. Interview takes place at St. ███████ ███████ Hospital in █████████ Ohio.
<Begin Log, [11/05/████ 1330]>
Dr. A. ████: How are you feeling?
Agent ████████: [groans] Like I've had half my face ripped off. How do you think I feel?
Dr. A. ████: I want to talk about the containment breach.
Agent ████████: [unintelligible]
Dr. A. ████: We have some questions.
Agent ████████: Of course you do.
Dr. A. ████: Starting with why there was foreign matter introduced into the containment unit.
Agent ████████: Do you have any idea what we were dealing with?
Dr. A. ████: Why don't you tell me?
Agent ████████: We were tasked to retrieve a 40 kilo… thing… with a BSL4 containment unit. You know how big those units are?
Dr. A. ████: I know the specifications.
Agent ████████: Like lugging a self-propelled washing machine. Now imagine dragging one of those into one of these places. You already got reduced mobility from the hazmat suit, got fifty kilos of gear, and you're walking into a house that has two or three decades worth of garbage in it. We have cat ████ ankle deep in places, trash bags split open, piles of soggy newspaper and junk mail, boxes of clothes, furniture that looked like it exploded, and ███████ cats everywhere— eyes everywhere—
Dr. A. ████: Can we return to the containment unit?
Agent ████████: We have ████ chest high in places, cats everywhere, and spaces so tight that we have to go single file. No way a guy in full gear can turn around, and forget the containment unit. Just one look and there's no way we can use
[DATA EXPUNGED]
Dr. A. ████: So it was Agent ████████'s idea?
Agent ████████: It was that, or pack it in. Can't get downstairs. So we bait the unit with the body and point it at the basement door. According to the briefing, it would be attracted to freshly dead… biological matter.
Dr. A. ████: And SCP-511 was attracted to the baited unit?
Agent ████████: The most nerve-wracking twenty minutes of my life, listening to that thing pull itself upstairs. Thud, thud, thud. And those cats, watching us. You know how freaky cat eyes look with night vision equipment?
Dr. A. ████: So you captured SCP-511?
Agent ████████: [laughs]
Dr. A. ████: What happened then?
Agent ████████: We got out as quickly as we could. No one can turn around, so we back out, all those eyes watching us. Staring…
Dr. A. ████: You were first out the door?
Agent ████████: Last in, first out. We all got out, for all the good it did. We thought we'd pulled it off. But the moment the containment unit rolled out the door… it… they…
Dr. A. ████: What happened?
Agent ████████: You ever see films of explosive decompression? That's what happened to it. Splattered itself all over the insides of the containment unit. And those cats, those ███████ awful cats. They howled. Then they rushed us.
Dr. A. ████: Did you attempt to contain the breach?
Agent ████████: You're kidding? Right? Two or three hundred of them? Not just the door, but the windows, dropping on us from the second floor. When I saw ████████ disappear under them, I just ran and locked myself in the van. I'm not proud of that…
Dr. A. ████: I'm not here to judge. I'm here to determine what happened, so it does not happen again.
Agent ████████: Well, you see what happened to me? That was one of them that got locked in with me. One. If you don't reclassify these things Keter, you're insane.
Dr. A. ████: I will be recommending updates to containment procedure.
Agent ████████: Yeah, while you're updating things, there's something else you need to update.
Dr. A. ████: What's that?
Agent ████████: The briefing was all about how SCP-511 is influencing these cats. That's wrong.
Dr. A. ████: How so?
Agent ████████: SCP-511 doesn't influence anything. It's the cats. They made SCP-511. And they made it because they hate us.
<End Log>
Closing Statement: Agent ████████ died three days later from complications due to blood poisoning. Three weeks after containment breach, a new incidence of SCP-511 was identified in ██████████ Ohio, 35km south-east of Site 511-47. Remote biopsies of this new incidence revealed genetic material identified as coming from three Agents of Mobile Task Force ████-█.
It seems that the “destruction” of SCP-511 might only displace it elsewhere. Until we better understand the vectors that propagate it, all SCP-511 need to be contained in place. Request for reclassification of SCP-511 to Keter is denied — O5-█

« SCP-510 | SCP-511 | SCP-512 »


Item #: SCP-512
Object Class: Safe
Special Containment Procedures: SCP-512 is held within the Site-77 Safe object repository. It is to be shut at all times, and testing during adverse weather conditions is forbidden. All outdoor testing proposals must be reviewed by Security Chief Anderson.
Description: SCP-512 is a stainless steel black umbrella with a nylon canopy and polished ebony crook handle. Maximum radius of canopy when open is 0.75 m. Make and manufacture are unknown. A taped patch is visible on the canopy section.
When open and pointed upward, SCP-512 exerts an upwards force in opposition to Earth's gravity, in a roughly dome-shaped area directly above itself, with a cross-sectional area of roughly 1.77m2. Precipitation and other objects will be suspended and deflected within this area of effect. SCP-512 has no effect when closed, or when held at a horizontal angle.
Despite SCP-512's efficacy against normal precipitation, it is inadvisable to use the object during severe weather. Through an as-yet-unknown process, the item's anomalous effect causes the air above it to become extremely ionized. This interaction also causes electrical current to greatly increase in amperage while in direct contact with the item. This causes the threat of direct lightning strikes to become exceptionally dangerous to any individual holding SCP-512, as evidenced through the death of its original owner, as well as D-512-33.
Additionally, electrical current appears to travel across the surface of SCP-512, causing little to no damage to the item's structure.
SCP-512 was recovered from a public park in [REDACTED], FL. Local emergency services had been summoned to evacuate the area due to reports of unusual lightning strikes. SCP-512 was discovered caught on a streetlamp and fully opened, with evidence of several lightning strikes in the immediate area. Its handle was noted to be covered in ash. Foundation personnel intervened after local newspapers began reporting on SCP-512's anomalous properties.
Addendum: Testing Summary
Upon recovery SCP-512 underwent standard testing, through which its properties were determined. A range of items were held 4 meters above SCP-512 and then dropped, after which a mechanical apparatus would open SCP-512.
Tested items include the following:

1 liter of purified water, dumped from a standard bucket
1 liter of orange juice from concentrate
approximately 1 kilogram of loose feathers
1 kilogram of ice cubes
The assorted contents of Junior Researcher Renfield's bagged lunch
A standard running shoe
A standard watermelon
SCP-1108
A 5.4-kilogram bowling ball
A 40-kilogram steel containment crate

Testing materials slowed in descent approximately .5 seconds after SCP-512 opened, with the larger and less solid items coming to a stop approximately .35 meters from SCP-512's surface. All material will remain suspended in the air, unless made to slide to one side and resume freefall. Liquids and particulate matter are weakly repelled from the center of the effect, while more solid objects can be held in place with minor adjustments to SCP-512's angle.
Addendum: Experiment D-512-33

Testing Item: D-Class personnel
Testing procedure: Object taken to Site-77 outdoors field for testing of the vertical distance of the anti-gravity effect.
An unexpected severe storm occurred during testing, and the rain-repelling properties of SCP-512 coupled with exceptionally low pressure caused a suction effect in the region directly above the object. SCP-512 pulled the D-class (D-512-33) holding it upward into the air and drifted on prevailing wind currents. D-512-33 was able to hold onto SCP-512 as it rapidly gained altitude. D-512-33 glided over Site-77 perimeter and into the surrounding area. It was observed that D-512-33 quickly developed skill in altering angle of anti-gravity effect to allow for semi-controlled flight. A helicopter was launched to pursue object and D-512-33. The object was recaptured following a lightning strike; D-512-33's remains were not recovered.

SCP-513

Item #: SCP-513
Object Class: Euclid
Special Containment Procedures: SCP-513 is to be suspended in a one cubic meter block of gelatin and contained within a soundproofed, climate-controlled cell. The gelatin must be inspected daily for any degradation or loss of integrity. An emergency inspection will be carried out immediately following any earthquake, explosion, or sonic event grade 2 or higher. Personnel performing the inspection are to wear earplugs and active noise-canceling earmuffs at all times while inside SCP-513's cell.
If the gelatin cube shows any signs of degradation (such as rips, tears, splits, liquefaction, or mold), SCP-513 is to be immediately removed and suspended within a replacement cube by a team of surgically deafened Class-D personnel. No other personnel are to enter the cell during this procedure.
Any sentient beings exposed to SCP-513 are to be monitored by at least two security personnel at all times. Under absolutely no circumstances may exposure victims be administered sedatives or allowed to fall unconscious. Any victim who does fall unconscious is to be terminated immediately.
Class-D personnel are to be terminated at the first sign of mental degradation. All other exposure victims may be terminated at their request.
If possible, SCP-513-1 is to be apprehended on sight.
Description: Physically, SCP-513 is an unremarkable, rusty cowbell. No marks or engravings are visible on its surface due to the large amount of corrosion. Attempts to remove the rust chemically or mechanically have had no success.
SCP-513 was recovered by Agent ██████ while carrying out Containment Reestablishment Procedure Mu at Site-██. SCP-513's clapper was firmly held in place by several strips of duct tape. A single scrap of paper was found along with SCP-513 (see Addendum).
Any noise produced by SCP-513 immediately induces strong anxiety in all sentient beings who hear it, regardless of their previous mental status. Exposure victims report feelings of being watched by an unseen entity and present elevated heart rates and blood pressure. Roughly one hour after exposure, exposure victims begin to catch glimpses of SCP-513-1 when opening doors, walking past mirrors, turning their heads, or performing any other actions that result in a sudden change in visual perception. Upon being sighted, SCP-513-1 reportedly turns away and runs out of view before disappearing without a trace. Questioning of bystanders indicates that SCP-513-1 is invisible to those who have not been exposed to SCP-513.
Sightings of SCP-513-1 reoccur every 14 to 237 minutes. This “stalking” behavior inevitably causes extreme sleep deprivation, as victims are frequently disturbed by SCP-513-1's presence in their quarters. Victims able to fall asleep before SCP-513-1's appearance report being physically assaulted by it. Upon the victim's awakening, SCP-513-1 flees as usual (see Experiment Log 513). This sleep deprivation, along with the mental stress caused by SCP-513-1's behavior, invariably induces paranoia, aggression, hypervigilance, and depression. All test cases but one have ended with the test subject's suicide.
Descriptions of SCP-513-1's appearance are largely unreliable. Test subjects are unable to provide complete accounts of sightings due to their exhaustion, degraded mental health, and disruptive hypervigilance. However, all interrogations thus far indicate that SCP-513-1 is a tall, emaciated humanoid with abnormally large hands.
Addendum: Text recovered from Site-██

You've seen it. Now he can hear you.
You've touched it. Now he can see you.

Item #: SCP-514
Object Class: Euclid
Special Containment Procedures: There is currently no permanent containment site for SCP-514 (See Addendum 2). SCP-514 is currently being tracked by Mobile Task Force Lambda-4 (aka "Birdwatchers"), who are under orders to observe SCP-514. In the event that SCP-514 strays near a densely populated area or an area where its presence will be easily noticed, Mobile Task Force Lambda-4 is authorized to use the █████████1 in order to manipulate SCP-514's migration patterns.
Access to SCP-514 and the █████████ is restricted to Mobile Task Force Lambda-4. Level 4 personnel may also have access, but must have O5 level approval beforehand. Any experiments and weapons tests with SCP-514 must be performed exclusively at the Foundation Advanced Weapons Research Facility.
In the event that SCP-514 risks public exposure or capture by rival groups, Mobile Task Force Lambda-4 is authorized to terminate the threat by any means necessary. It is highly recommended that such threats be terminated before they reach SCP-514's "zone of influence", though this is not strictly necessary.
Description: SCP-514 is a flock of Columba livia domestica, or Homing Pigeons. Visual analysis confirms that these pigeons are in fact the kind used in White Dove Release ceremonies. However, the type of ceremony they were used in, or the identity of who bred these doves is currently unknown.
What makes SCP-514 unusual is the "weapon and aggression nullification zone of influence" it seems to project around itself. This zone of influence projects itself in a roughly five hundred (500) meter radius around the flock, though this estimation varies depending on the flock's size. This zone of influence renders every known type of weapon inoperable and often destroys affected weapons after prolonged exposure. For instance, firearms will immediately jam or misfire, explosives will be rendered inert, and melee weapons will decay into dust. Also, the items SCP-514's zone of influence destroys appears to be selective. For further details, see Experiment Log 514a.
In addition to its weapon nullification ability, SCP-514 can also somehow suppress violent emotions and intent in sentient beings within the zone of influence. Interviews with staff and civilians who had been exposed to the zone of influence said that they felt very calm and content, even when they felt stressed and angry just moments before. For further details, see Experiment Log 514b. Currently, there appears to be no harmful or lasting effects to being exposed to SCP-514's zone of influence. Rigorous physical and psychological screening of individuals exposed to the zone of influence showed nothing out of the ordinary.
SCP-514 was first discovered when numerous reports of weapons stockpiles were reported as having been destroyed in numerous African nations. While the initial reports were written off as poor maintenance on the part of the owners of the weapons, additional reports of sightings of a flock of homing pigeons, which are uncommon in Africa, garnered Foundation interest. An investigation team was sent to track SCP-514 where they encountered a team claiming to be affiliated with the Manna Charitable Foundation, who were also tracking it.
The MCF members admitted they released SCP-514 in an effort to "end all conflict in Africa", despite not having a reliable way to control its movements. Unfortunately, the MCF was apparently unaware that SCP-514's aggression suppression effects were only temporary once affected subjects were no longer within its zone of influence, and they would resume hostilities with improvised or primitive weaponry once SCP-514 left. In addition, SCP-514's random movements caused only certain regions to be disarmed, leaving them vulnerable to invasion by their unaffected neighbors.
It took another three weeks before MTF Lambda-4 were able to bring the █████████ to control SCP-514's movements. The MCF members then challenged the Foundation team for possession of both SCP-514 and the █████████. Since both parties were still under SCP-514's effects, the conflict was resolved through a single round of rock-paper-scissors, with the Foundation being the victor. The MCF members then fled the area before they could be further questioned. The origin of SCP-514 and how it came into the possession of the MCF remains unknown.
Experiment Log 514a
Various tests were performed by continually using the █████████ to have SCP-514 circle around the Foundation Advanced Weapons Research Facility.
Firearms: Items used: Glock 9mm handgun, Colt .45 1911 handgun, MP5 submachine gun, Thompson submachine gun, M16 assault rifle, AK-47 assault rifle, SAW, M24 sniper rifle, [DATA EXPUNGED]. All weapons confirmed to be in working order.
Result: All weapons, when tested, failed to fire. Later inspection showed that all weapons suffered from various mechanical failures that rendered the weapons useless. Ammunition exposed to the zone of influence also failed to fire when loaded into weapons not affected by the zone of influence. Chemical propellant was found to be rendered completely inert.
Explosives: Items used: One standard hand grenade, 28.35g (1oz) of dynamite, 28.35g (1oz) of C-4 high explosive, 28.35g (1oz) of thermite, one 81mm high explosive mortar round, one 120mm tank shell, [DATA EXPUNGED].
Result: All explosives were immediately rendered inert when exposed to the zone of influence. In addition, any detonators or components that would aid in the detonation of the tested devices suffered mechanical and electronic failures.
Melee Weaponry: One combat knife, one steak knife, one baseball bat, one katana, one poleaxe, one spear.
Result: All weapons, with the exception of the steak knife and the baseball bat, were rendered useless through accelerated rate of decay. However, when the steak knife and baseball bat were used in a threatening manner, both items were immediately rendered useless through accelerated decay.
Weapons of Mass Destruction: One liter of Sarin nerve gas, 1 gram of weaponized Anthrax, one tactical nuclear warhead.
Result: All weapons rendered completely inert. All samples, including the nuclear material, were completely degraded, and instruments recorded no radiation. In the case of the warhead, the electronic detonator was also rendered useless.
Conclusion: SCP-514's zone of influence appears to be able to render any conventional weapon inoperable. Also, the damage each weapon suffers is directly proportional to how long the weapon is exposed to the zone of influence. In under an hour, all weapons eventually degraded into dust. The zone of influence is also somehow selective, being able to discern items that are actively designed as weapons from items that are potentially dangerous, but not specifically designed to be weaponized. However, SCP-514 also appears to be able to discern when an item will be used for violent intent, and said item will be directly affected by the zone of influence.
It remains unclear whether SCP-514's ability to selectively target certain weaponry and discern hostile intent is a property inherent to its zone of influence, or if it is directly controlled on the part of SCP-514 itself through some form of group intelligence.
-Dr.███
Experiment Log 514b:
Live subjects were exposed to SCP-514's zone of influence for an extended period of time. The subjects were divided into two groups: Voluntary test subjects drawn randomly from the general population as the control group, and Class D personnel with a history of violent behavior as the test group. Tests showed that the test group's violent tendencies were completely suppressed, and acted in a similar fashion to the control group. Suppression of the test group's violent tendencies occurs even after the subjects leave the zone of influence, though the duration is directly proportional to the time spent exposed to the zone of influence. Live testing against sentient SCPs proposed, pending O5 approval.
-Dr.███
Addendum 1: Several high ranking members in the Foundation's military branch, as well as various associated government agencies, have expressed interest in weaponizing SCP-514. There is great strategic and tactical value in an asset that can effectively neutralize an entire enemy army's arsenal in a short period of time. There are also requests to test SCP-514's zone of influence against several Keter-level SCPs. However, access to SCP-514, as well as the █████████, remains restricted. O5 Command is currently deliberating the issue.
Addendum 2: All attempts to capture SCP-514 for containment and study have been met with failure. Every Agent, Doctor, and researcher sent to capture SCP-514 steadfastly refused to complete the mission. This is most likely a reaction to SCP-514's zone of influence. Attempts to remotely capture the flock through the use of drones or long ranged devices have resulted in the destruction of all equipment involved.
It is evident that SCP-514 interprets any attempts to capture it as a hostile act, triggering the nullification effects of its zone of influence in response. Again, it is still unclear whether this is a property inherent to SCP-514's zone of influence or is regulated through a group intelligence among the flock.
Surveillance with Mobile Task Force Lambda-4 still in effect, with the use of the █████████ authorized.
Addendum 3: As of ██/██/20██, all members of Mobile Task Force Lambda-4 are required to be proficient in various non-violent, competitive activities, including but not limited to: Sports, board games, card games, videogames, trivia, riddles, and rock-paper-scissors.
Are you serious? The fate of one of our SCPs could be decided on the outcome of rock-paper-scissors?!
-O5-██
I assure you sir, you have nothing to fear. We are dead serious about these matters.
-Captain ████████, Mobile Task Force Lambda-4 "Birdwatchers"
Note: Captain, couldn't you have chosen a more… dignified… game as your primary conflict resolution method? Seeing two grown men in all-black tactical gear taking a children's card game so seriously is… off-putting.

Item #: SCP-515
Object Class: Keter
Special Containment Procedures: SCP-515 is to be kept entirely manacled to his sleeping quarters to the point of near-total immobility. If SCP-515's enclosure is seen to be empty, top priority must be placed on immediate recapture. Locomotion or simple twitch-response behavior exhibited by SCP-515 is to be noted and reported to research and emergency staff.
If SCP-515's legs or arms are in working order, they must be broken immediately to minimize his sleepwalking speed in the event of escape [see Addendum 515-01]; the neck, however, cannot be broken, due to the risk of death [see Addendum 515-02]. Instead, it must be held immobile by a brace covering up to the chin and down to the shoulders. Amputation and severing the motor nerves of the limbs are also not recommended, due to similar risks, and all muscle relaxants tested thus far have resulted in convulsive reactions and as such should not be administered. Restraints are not to be unfastened at any time for any reason, and the room is not to be opened for anything but standard research purposes unless emergency conditions require it. Maintenance crews and D-class are also to be kept away from the enclosure unless otherwise noted.
Description: SCP-515 is presently a Caucasian male of the approximate age of 14; no applicable birth certificate has yet been found, so all relevant personal information is the product of hypotheses and the subject of guesswork. His basal metabolic rate is comparable to that of a blue whale or a mammal of greater size, but mass is slightly below average for humans of similar ages.
Despite ignorance of all other bodily needs, and despite attempted interference on the part of researchers, SCP-515 has yet to be observed in a state of consciousness apart from Stage N3 dreamless sleep. For the entire duration of containment, SCP-515 has ingested no food or water and has passed no waste; what has kept him alive for so long is still under study.
Even asleep, SCP-515 has been known to speak on rare occasions. Little of what is said is intelligible, and that which can be heard is typically incoherent, similar to the speech of a person in the grip of delirium. Portions have been recorded for future research; no noticeable difference in the movement of SCP-515-1 has been noted during these periods.
Records of SCP-515 in somniloquy

"The vessel cannot view the [incomprehensible], it simply moves in time with the sea." (26 Dec 19██)
"There are more, there are always more." [repeated for several minutes] (13 Apr, 20██)
[DATA EXPUNGED]
"Can you see where I am? Can you breathe? Can you move?" (06 Aug, 20██)

Whenever SCP-515 moves in any capacity, one or more of a number of celestial objects, mostly asteroids, move as well. The estimated nineteen objects [heretofore collectively named SCP-515-1] vary in diameter from 1.5 km to 33.6 km; the largest of these is roughly 133% the size of the object that caused the Vredefort impact crater in Free State, South Africa. Regardless of the direction of SCP-515's motion, SCP-515-1 only ever moves toward Earth. A twitch of a finger or toe typically corresponds to a movement of about 140 kilometers; comparable movement of a limb indicates motion of SCP-515-1 on the scale of 460 km or more. Sustained motion, such as sleepwalking, has been demonstrated to correlate with the objects traveling toward Earth at velocities reaching 280,000 kilometers per hour. The rise and fall of SCP-515's chest unfortunately must not be stopped and, according to Foundation satellites, corresponds with a movement in the celestial objects to the degree of 10 km per respiratory cycle.
If SCP-515 is killed, it is presumable that someone with a similar anomaly will appear someplace else on the planet [see Addendum 515-02]. Due to the difficulty and danger of having to find such an individual with no initial leads, it is stressed that killing SCP-515 is never an acceptable course of action.
Addendum 515-01 On a number of occasions, SCP-515 has been freed from his restraints by unknown means. No physical presence has been seen to cause this, and the restraints themselves have only ever looked as though they remained untouched during these occurrences. Because of this, it is yet uncertain whether it is his own doing that he escapes, or that an outside force is interfering without being noticed. If this occurs, all available resources at Site-██ must be directed toward SCP-515's location, recovery, and placement into enclosure.
Addendum 515-02 The designation of SCP-515 was formerly given to a middle-aged woman from ███████, Guatemala, with a condition identical to that of the current designee. She, too, was found with no personal history and with no connection to any people in the surrounding area, despite having lived in a small and closely-knit community. After the realization of her connection with SCP-515-1 and her coming into care of the Foundation, both a tight-fitting full-body cast and the routine breaking of the legs, arms, and neck were used to prevent the subject from moving; both she and the present SCP-515 have been known to escape confinement, including such a cast, so keeping major bones broken was used as a method of keeping movements slow when such events transpired. However, on ██/██/19██, complications from a pair of shattered vertebrae proved fatal. SCP-515-1 was noted to have stopped moving after this occurrence, and after several months without any change the Foundation presumed the matter closed.
On ██/██/19██, motion of SCP-515-1 restarted. A thorough search returned the result of the current designee after twenty-two days; he was taken into custody immediately and subjected to revised containment policies that prevented the breaking of the neck. SCP-515-1 had moved a total distance of █████ km from the start of the search to its finish, and has moved an estimated ████ km during his stay at the Foundation.
Due to the motion caused by SCP-515's respiration, the Foundation continues to allocate resources toward finding an efficient manner of neutralizing the threat presented by the potential impact of SCP-515-1.

SCP-516 on testing range

Item #: SCP-516
Object Class: Safe
Special Containment Procedures: SCP-516 may be kept in an Anomalous Vehicle Containment Bay. Routine vehicle maintenance should be carried out on a bi-weekly basis. SCP-516 is not to be provided with fuel or ammunition except under controlled testing circumstances. Following Incident 516-1A, no personnel with a history of military service should be assigned to SCP-516.
Description: SCP-516 is a standard model T-55 main battle tank. Records indicate it was manufactured in 19██, at ████████████ Plant, Kharkiv, Ukrainian SSR, and that it had a normal period of service in the armed forces of ██████████. It exhibits wear and tear consistent with its age.
The only part of SCP-516 which is known to exhibit anomalous properties is its main armament (presently a 100mm D10 tank gun) and turret assembly, from here designated as SCP-516-1. However, as SCP-516-1 has been replaced several times throughout SCP-516's service life without any apparent effects, its anomalous properties seem to be inherent to SCP-516.
When loaded with compatible 100mm ammunition SCP-516-1 exhibits a limited degree of autonomy. When an entity attempts to damage SCP-516, SCP-516-1 will track and fire on it if it is physically possible to neutralise the threat, regardless of whether SCP-516 is crewed. It will not respond to threats outside its range or traverse, such as aircraft. This phenomenon only occurs if the entity possesses reasonable means to damage SCP-516; for example, SCP-516-1 will not fire on a person attempting to attack SCP-516 with their fists.
SCP-516-1 may be operated manually, but is selective about its targets. In general, it will only 'permit' its operator to fire on nonliving targets, nonsapient biological targets or armed humans. Under these circumstances it will fire as a normal armament piece. If a target does not satisfy these conditions (essentially, being an unarmed, sapient being) SCP-516-1 will jam. Attempts to prevent jamming through maintenance or parts replacement have failed.
SCP-516 appears to go to extra lengths to prevent injury to unarmed humans, deliberately placing shots from SCP-516-1 to avoid collateral damage. When operated manually, SCP-516-1 places a higher priority on preserving unarmed life than eliminating armed targets; it will jam if directed to fire upon a group of persons, of which only some members are armed.
It should be noted that none of SCP-516's other armaments exhibit these properties, and appear to be perfectly normal.
SCP-516 was brought to the attention of the Foundation in 20██, when it was slated to be broken up for scrap. Due to a bureaucratic oversight, ammunition had not been removed from SCP-516-1, causing it to open fire with ██ casualties. The ensuing ████████ government investigation was noted by Foundation operatives, and it was thought worthwhile to take SCP-516 into custody.
Addendum 516-1: An upgrade to Euclid status is being considered in light of Incident 516-1A, as this lends credence to Dr. ██████'s theory that the SCP may be sentient in some form. Additional security measures have been approved for SCP-516's containment.
Incident 516-1A synopsis: During routine testing of SCP-516, SCP-516-1 immediately fired upon a group of unarmed personnel in range as soon as it was loaded with ammunition, leading to the death of two (2) D-class personnel (D-505, D-596) and one (1) Foundation officer, Agent ███████.
Subsequent investigation showed that D-596, one of the casualties, had attained his D-class status following a criminal conviction for treason against his native country, ██████████. D-596 previously held the (English equivalent) rank of Sergeant in the ████████████ armed forces, from which SCP-516 was acquired.
No other possible links to SCP-516 with D-596 or the other casualties have been found at this stage. This marks the first time SCP-516 has attacked unarmed personnel; further investigation and safety precautions are warranted.
Addendum 516-2: SCP-516 Testing Log

« SCP-515 | SCP-516 | SCP-517 »


Item #: SCP-517
Object Class: Safe
Special Containment Procedures: SCP-517 is to be kept secured within Containment Locker 51164 in Site-66, facing away from the doorway. A thick sheet is to be draped over the item at all times. Testing is currently prohibited, as the nature of the manifestation invariably causes a low-level containment breach. If SCP-517-01 is triggered, personnel are instructed to report to their immediate superior to enact Protocol 517-001.
As of Incident 517-1997-M, SCP-517 is to be kept in a dedicated cell at all times. An opaque black sheet is to be kept bound around the object at all times. As of 08/25/1997 ██/██/2002, no more testing is to be conducted on SCP-517 without Site Director's approval.
Description: SCP-517 is a fortune-telling machine. Item stands approximately 2 meters tall, containing a mechanical puppet and an electric candle within a glass and wooden case. Examination has shown an internal layout consistent with similar machines. On the top panels the words "Grandmother Predictions" are painted on built-in signage. The puppet within is in the shape of an elderly woman, with a white blouse and a blue shawl. Item's power cord has been severed approximately 15 centimeters from its base; it appears to have been inexpertly separated from its original power source. No reaction occurs if a coin is inserted into the slot.
The item will energize automatically, once an hour, if an individual (hereafter the "Target") enters its field of vision. The puppet will turn to face directly at the Target, dispense a "fortune card" from the slot on its front, and cease function. Process is fully mechanical, and item does not show signs of awareness. See Addendum for a transcript for examples of "fortunes".
The individual who "activated" SCP-517 will become the Target of an entity or number of entities who will attack at 1:43 AM local time the following morning. The Entity or Entities (hereby SCP-517-01) appear as a varying number of long, multi-jointed arms (between ten and three dozen), initially appearing from a single area. Arms seem to be completely corporeal, and can apparently extend indefinitely. Entity will immediately rush towards and attempt to grab and capture the Target or Targets. If the hunt is made sufficiently challenging, additional arms will begin to constantly generate in close proximity to the victim in order to facilitate an easier capture.
Chosen areas are usually low, cramped, dark areas such as basements or closets, and will not shift during a given assault. In all instances, Targets have been captured, rapidly dragged into SCP-517-01's chosen area, and savagely beaten until sunrise. Entity has been documented reaching from the ventilation system of an office building, drawing a Target into a drop-ceiling, pulling a Target under a bed, and drawing a Target through a sewage grate. Any attempts to intrude on this event will result in human aggressors being drawn into the assault. The remains of victims are reduced to [REDACTED]. To date there have been no survivors.
If more than one individual activates the item in the span of one day, all will become Targets of the following night's assault. SCP-517-01 will appear from multiple areas while "hunting" multiple Targets. However, due to the resultant chaos during the test (517-34c) in which this was discovered, all measures are to be taken to avoid multiple activations.
Remote viewing of the expected points of origin of SCP-517-01 during testing revealed arms extending from points around corners and otherwise off-camera, eventually crowding out the video feed. Fragmented, unidentified human DNA has appeared in the areas utilized by SCP-517-01; ultimate origins are still currently unknown.
Addendum - Fortunes
Samples from several "fortunes" as read by SCP-517.
