Nightmare Fuel: SCP Foundation

Look closely.
"You look afraid. Don't be afraid. This is a dream. The last dream you may ever have, for nightmares are coming."

No wonder the SCP Foundation wants to contain these; the stuff they contain will make you stay awake for days.

NOTE: Examples for the game based on the wiki go HERE.

Please remember that Weblinks Are Not Examples - a description of what exactly makes the SCPs so scary would be nice.

Please add new examples to the bottom of the page.

    In General 
  • The real crowning piece of terror inherent to nearly every single SCP object page: before you even get to the description, you get one or more paragraphs describing the special containment procedures needed for each object, forcing you to imagine just what requires this kind of containment process. These procedures often include battalions of elite commandos with automatic weapons and body armor, 3-meter-thick titanium cubes, on-site nuclear self-destruct systems, deep underground or undersea locations, overwatch from AC-130s, unimaginably extensive monitoring equipment, people with unusual skills or attributes (such as fluency in Ancient Sumerian or a "marked sexual deviancy"), vats of hydrochloric acid, bulletproof glass, and other SCP objects. In other words, stuff that no government in their right mind would ever authorize. It's around then that you know what you're dealing with.
  • The sheer knowledge that if it wasn't for the Foundation, the world might have ended already. Also, the sheer knowledge that despite the existence of the Foundation it just might end anyways, since several objects that could cause The End of the World as We Know It require only one tiny slip-up to activate, and there are several others the Foundation cannot do anything about. Then you start to figure out that the world has ended before, they hit the Reset Button, and you are none the wiser.
  • Goddamn it, the whole website. The titles are very mundane numbers and stuff, never know if you're clicking on something funny, squicky, or an insane Eldritch Abomination that will keep you awake for days. And the pictures...oh, god, the pictures...
  • It's telling that sometimes the horror of an SCP object doesn't come from the SCP itself, it comes from the people assigned to it. For example, SCP-1310 or SCP-1337. The organization literally holds the fate of the world in their hands, and they're disturbingly prone to having the Artifact Collection Agency researcher equivalent of the Insane Admiral.
  • Then there are more subtle things, like the turnover in Class D personnel. Not to mention the implication that some Class D personnel are hired as Schmuck Bait, with the full knowledge that they'll ignore their orders and do something stupid... just so that the scientists will see what happens.
    • D-Class personel are derived from the ranks of convicted criminals, typically those on death row. However, if there's a shortage, Protocol 12 can be enacted, which permits recruitment of D-Class personnel from other sources, such as "political prisoners, refugee populations, and other civilian sources." Considering that simply handling quite a few SCPs, not to mention various experiments and tests generally end in rather messy, unpleasant deaths for the involved personnel-Oh! And even if they survive, they are often terminated after a month anyway.-the Foundation basically goes through D-Class personnel like popcorn. Given that violent criminals are aplenty, but still a minor portion of the human population, it makes one wonder just how often the Foundation has been forced to enact Protocol 12 and just how many completely innocent and merely unfortunate people have ended up as D-Class personnel and meeting their inevitable ends.
    • This 'explained' SCP gives this some more Fridge Horror. D-class stands for 'drapetomaniac class'-they were using slave labor to test SC Ps as a means to get rid of the more belligerent slaves, and only switched to prisoners after the Civil War...but even under the Cartwright Protocol still heavily preferred black people.
    • According to this story from the Spanish-language branch, the "termination" of D-class personnel doesn't refer to killing, at least on the present time. It used to mean so, but the decrease on the application of death penalty and the subsequent reduction on human resources forced the Foundation to reduce the monthly culling to the aggressively violent and the ones who were compromised by the SCP they were assigned to. Instead, at the end of the month the surviving prisoners get the last month wiped of their minds with amnesiacs and are reassigned, so they eternally believe that they are working just a month in a science lab to shave off years from their sentences. This means that they get forcibly what the ex-staff of 231-7 gets voluntarily. It then shows a couple of D-Class that the researcher giving the conference maintains around as his assistants; they were lobotomised to have retrograde amnesia deliberately inflicted on them. You almost want them to get mercily killed.
      • Oh, and don't expect them to be released any time soon because the Foundation depends so much on the D-class that it could simply collapse without them, leading to innumerable security breaches and the release of every SCP in this page and then some.
      • The same story has this jewel (translated for your convenience):
    Non-D class personnel is never demoted to D-class. Never. Remember those jokes we discussed before? This is one of those. If we have to apply a fulminating and definitive disciplinary sanction to a Foundation member we don't beat the bush around that much.
  • One of the most disturbing things about the SCP series is that almost all of them were located and contained after coming into contact with a regular civilian human being going about their business, with no knowledge of what the thing is, how it works or where it came from. Consider that there's an indeterminate number of supernatural objects that could qualify as an SCP scattered around the world, and you could run into, say, an undocumented Keter-class at any minute during your daily routine. Or even a Euclid-class, which only seems safe in comparison to Keter, or even something worse. Yes, there's things worse than Keter-class in the SCP foundation. The SCP world is a Crapsack World of the highest order considering how very likely all three options are, the horrifying things needed to contain them, and how very often The Extremist Was Right. And given that there's well over a thousand SC Ps, and the bizarre anomalous events and appearance of SC Ps that can happen anywhere, at any moment, to anyone, and the very real possibility that the world has ended several times and the Foundation has rebuilt it (How many times have you lived through ''this'' thursday just this week, huh?) repeatedly, the world of the Foundation is a place of constant nightmare fuel and incomprehensible horror.
  • What some find most disturbing isn't that they'll do things like what they do to poor 231-7, though that's quite sufficiently disturbing. It's how they treat people who qualify as SCPs, essentially imprisoning them for life without trial, without charges, and in at least some cases, with no evidence at all that they're dangerous or likely to become so.
  • There was an SCP on the original message board that was a small sphere which quite simply increased in temperature. Rising, and rising, and rising. They attempted to cool down the object by storing it with ice, in freezers, with liquid nitrogen, but that only temporarily slowed the process... The temperature just kept rising. If you have any knowledge of thermodynamics, you'll know why this is worrying.
  • Dr. Clef. Even if we take everything he says about himself with a grain of salt there is a mountain of evidence in various entries, logs, and reports that suggests that he is something far, far worse than any of the actual SCPs. The fact that his head is always replaced with something else in photographs is actually one of his least disturbing quirks. And he is the guy in charge of SCP Training and Development.
  • It's one thing to read about the Foundation personnel doing horrible, ruthless things to contain dangerous or even "potentially dangerous" SCPs. It's not even so bad to read about Foundation personnel doing cruel and messed-up things for kicks—after all, it must take a strange, not conventionally moral person to survive working there for very long, right? But then there's examples like SCP-042 and SCP-948, where there's a very strong implication that the Foundation is containing not merely harmless but good, benevolent, mystical creatures against their will, and possibly even endangering the world by doing so. SCP-042 in particular seems to be written specifically to highlight the cruelty of the Foundation, particularly since for SOME REASON they won't allow the poor thing to die.
    • Knowing the Foundation, that "reason" can probably be summed up as For Science!.
    • SCP-948 is vaguely dangerous, but the fact that the Foundation terminates people who go feral after repeated exposure to it kinda underscores the "they're evil" idea. Being essentially uncivilized doesn't make one a danger; there's no need for it. It's also interesting that the 948's effects include the removal of mental disorders/negative emotions and the removal of traces of human civilization (or domestication, in animals). It implies that human systems of thought, language and behaviour are some sort of harmful mental aberration, at least in the view of whatever the SCP is.
  • While their treatment of D-Class personnel may be abhorrent, the way the organization treats certain SCPs (such as harmless ones, or non-hostile intelligent SCPs) indicates that many of the staff are more or less psychologically normal. Which means that normal people are engaged in the caretaking of these things, which may also include the horrible, horrible things they have to do to contain some of them.
  • Dr. Bright. Aside what he did to his own brother, he is a god of Fridge Horror. Just look at this list. Sure, it's damn funny, but then you realize, that he is one of most important people in charge of all this gallery of horrors and is an irresponsible sociopath. It's like a monkey being in control of nuclear arsenal.
    • Word Of God says that the list is not in-universe. So, although Bright is an asshole, he's not a completely irresponsible asshole.
    • But then again, half the time he is a monkey, so it kinda makes sense.
    • Bright's own life is a Fridge Horror in and of itself.
  • On the page "Log of Anomalous Objects", there's a mention of a piece of charcoal that writes (regardless of what the writer is using it for) "Please help me! I'm trapped in the charcoal!" every few seconds. And the foundation found it too boring, and put it into storage.
  • The SCPs that specifically target children. Baba Yaga, the living pinata that turns children into candy that turns children into more murderous pinatas, the children's mittens that rot flesh when worn, the kiddie pool that can teleport people to space, Bobble the Clown, the treehouse, the child-controlling bone flute that makes its wielder abusive towards children...
  • Dr. Wondertainment, and the fact that her SCPs are made for children.
  • And for Nightmare Fuel it is really hard to beat...the Ethics Committee. There is no canon, and even if there were the Ethics Committee would never acknowledge this document, but the thought that someone is evaluating the moral cost of everything the SCP does, and they are still doing so much of what they do... that can keep you up at night.
    • It's like a reminder that yes, horrible things are done. Yes, the SCP is doing a lot of evil with their actions. But would you prefer the alternative? SCP stands for Secure, Contain, and PROTECT. They are here to protect the general public, even if it doesn't seem that way all the time.
  • Fucking hell, practically any SCP labeled under the transfiguration category will involve gratuitous amounts of Body Horror to the human body.
  • Project Olympia. Using ten different SCPs, and claiming the lives of over 40 human test subjects. Its stated aim? "To successfully create an artificial humanoid through the use of several SCPs, and use it to the benefit of the Foundation". It worked. Just read everything the resulting "woman" is capable of. The foundation then decided to begin mass production.
  • According to the page SCP-8900-EX, the concept of color as we know it was completely different. Think that sounds bad/not bad enough? Try imagining this from the perspective of the Earth back when people remembered what the world was supposed to look like. Or the fact that our entire world has been corrupted and we've just been made to not notice it. Or, heck, these excerpts from an addendum from O5-8note :
    Gentlemen, we have failed. SCP-8900's effects have become so widespread as to be commonplace. The natural blue of the sky has been replaced with a gross and unnatural shade, and the green of trees has been equally corrupted. SCP-8900 has brought ruin down upon the entire visible spectrum, and we have been overrun. [...] By the time this message reaches those of you cleared to receive it, Foundation resources on a global scale will have released vast amounts of compound ENUI-5, our most subtle amnesiac. Worldwide, men and women who do not deserve the horror wreaked upon them will pause, confused, then resume their business, confident that this is the way it has always been, never knowing what they have lost. Only the photographs not affected by SCP-8900's taint will remain to tell the truth. I regret this, gentlemen. I regret it deeply.
  • The fact that there are uncontained SCPs Because of their size, abilities, or other attributes about their nature, all the Foundation can really do is track their activities, keep people away, and suppress information about them. Otherwise, these things are completely free.

  • Someone successfully managed to make the memory wipes terrifying. Doubles, of course, as Paranoia Fuel. At any moment, you could be abducted and traumatized until you can't remember your own name or who you are. Because of something you weren't even aware of. Co-worker behaving oddly? You're screwed, buddy! Good night!
  • The Great Short Story Contest. Given that the contestants must include at least some of the twisted geniuses responsible for the entries above, we should expect some doozies, but here's the kicker: The theme for February? Post-SCPocalypse.
  • Opportunity Knocks. Apparently based on a recurring nightmare of the author's...
  • This story, especially the ending and the fact that there is no mention of which SCP it is. Watch me fly! Then again, the ending of the last part could also be construed as a Crowning Moment of Heartwarming.
  • According to The document recovered from the Marianas Trench, they frequently have containment failures so massive that it kills nearly every person on earth, and the survivors use SCP technology to repair the devastated planet, clone the dead and make them think nothing happened, with geologic features covering up bigger damage (evidently the Marianas trench used to be a dry land ravine). You'll never know how many times you've died to make it to the end of the "week", or how many years have passed between Monday and Friday....
  • And the And Then I Died Contests were games, but they involve stories of deaths involving the SCPs in some way, and you get to guess which was involved. And most of the stories take place before the SCP in question came under the Foundation's control. They not only remind you of what these things can do to ordinary human beings, there's the added scariness that, however horrible the Foundation may be, it would be SO MUCH WORSE without them.
  • "Nor Shall My Sword Sleep", or the point of view of inhabitants of SCP-1235. Imagine that everything you knew about reality turns out to be false, and that your entire world suddenly finds itself in the mercy (or rather, lack thereof) of entities who can tamper with your universe without remorse about the torture they're inflicting upon everyone.
  • This tale about an unusual DVD that The Foundation came into possession of. It involves a trio of explorers, all of whom speak a strange, unknown language, filming what appears to be a nature documentary. It starts out alright, but then things get weird when they film a flock of vultures eating a dead camel. The camel suddenly wakes up and drives off the vultures, then stands there with its exposed organs dangling from its belly. We see more creepy and weird stuff afterward, such as a rhino-eating plant, tribe of humanoid lemur-like creatures, living Utahraptors, a giant ground sloth with six legs, a Multi-Armed and Dangerous aquatic predator, two giant floating creatures, and a pair of bloated worms. But the most horrifying part is when the researchers enter some slums filled with severely malnourished humans. One of them promptly attacks the subjects and says the following:
  • Conviction is a good contender for most horrific story on the entire site. A drunken man claims that he knows what SCP-001 really is, since he was in charge of it. Specifically, it was the Foundation's attempt at containing a deadly virus. What did this virus do? It slowly turned a person's muscle mass, organs, and body tissues into fat, raising their body temperature and ending with them being immolated. The problem was that virus only infected select groups of people and the Foundation couldn't understand why. What were these groups? Jews, Romani, and Homosexuals. That's right, he's implying that THE FOUNDATION WAS RESPONSIBLE FOR THE HOLOCAUST. Not only that, but the guy they got was just as anti-Semitic and racist as the real Hitler, whom the Foundation had secretly replaced to take control of the Nazi party. He added people to the roster, like Slavs and the mentally retarded, because he thought it would be all for the good of humanity.
    • There's also the implication that the virus is still around today, but is luckily contained in a small region and surrounded on all sides by enemies. Where could they be talking about?

    SCPs 1000 to 1999 
  • SCP-1000. My god. It's Bigfoot.
    • Bigfoot used to be the dominant species on the planet. Humans were hunted to near-extinction, put in zoos, etc. Meanwhile, Bigfoot created things even humanity can't comprehend. Organic technology, mostly. Eventually, humanity acquired Bigfoot's technology and used it against them, wiping them from the planet, destroying their minds, their technology, everything. Then, humanity wiped its own minds, forgetting everything they had done and rising to become the dominant species. However, recently, Bigfoot has been regaining its mental capacities...
    Director Jones: You think Bigfoot is funny because we want you to think Bigfoot is funny.
    • And later on, they leave us this message:
    we forgive you;
    given choice for now, not forever;
    let us back in
  • SCP-1042 is a stone brick that has the strange property, when exposed to an electric current, to record and broadcast events happening near it, like a spectral videorecorder. But that's not what makes it creepy, nooooo... It's the only artifact that seems to detect the presence of strange, dark hooded figures in the vicinity, who sometimes slightly interact with nearby objects for causing accidents. Sometimes they cause LETHAL accidents for their own purposes that have far-reaching butterfly effects. AND THEY KNOW THEY'RE BEING WATCHED BY THE SCP AGENTS.
  • Speaking of scary teddy bears, SCP-1048 is a vicious subversion/deconstruction of "Team Pet"-style SCPs that aren't kept under close watch because they're considered harmless. It provides some excellent perspective on why the Foundation continues to use the methods that they use when handling SCPs classified as "Safe." It collects human body parts and uses them to make new teddy bears. Once it even aborted a pregnant woman's child while she slept for use as raw material. Yeah, there's a good reason it was reclassified Keter.
    • Scary enough? No? Would you like to read the diary of the little girl who had it first?
    • There's also the incident that got it reclassified. While walking around the facility, its first creation, SCP-1048-A, let out an intense shriek that could be heard for 10 miles. It caused ear-like growths to grow to cover the body of everyone who heard it, and they all soon died of asphyxiation due to the growths forming in their esophagi and mouths.
    • There's also this little part:
    "Subject made no attempt to interact initially, until a burst in its seams revealed what appeared to be the hand and arm of a human infant poking out and grasping at the air. At the sight of this, a female researcher named ████ ██████ screamed, and SCP-1048-B reacted by emitting a high-pitched cry similar to that of a human infant. The subject then attempted to [DATA EXPUNGED] the screaming researcher, causing massive internal damage. In the ensuing chaos, a security team was forced to [REDACTED] both the researcher and SCP-1048-B."
    • P.S. They later mention how they found a female researcher bleeding unconscious. It was discovered something forcibly ripped out her fetus
  • Speaking of scary teddy bears, SCP-1055 appears to be a harmless little one, but it can change in size and shape into an enormous Eldritch Abomination based on how many people know about it. Worse, its behavior is also influenced by how people aware of it generally think of it; hostile and fearful awareness make it act in a more hostile and fearful manner. It has no upper limit to the size it can achieve, so even what starts as benign awareness can quickly grow fearful. The SCP is believed to be capable of causing an XK-class end-of-the-world scenario, and the only way they have to contain it is to have a mentally retarded man constantly hug it. The only way anyone thinks they can destroy it would be to kill at least 80% of all people who are vaguely aware of the existence of the SCP...which now includes you for having read the page for it. And this entry.
  • SCP-1076: Say your a little kid whose parents discovers a 3-5 year old child who looks like they suffered from severe abuse. As responsible and sympathetic human beings, it's only natural they take him/her back and care for them until they get better. But then, after a while they begin to show a little TOO much concern for this child, to the point they begin to forget looking after YOUR needs. Eventually they stop paying attention to you and you begin to suffer from starvation and neglect. You become lonely, withdrawn, and depressed, desperately in need of the love that has become monopolized by the strange new child. Eventually your condition attracts the attention of concerned school authorities and social well-fare agents. As they investigate the cause for your misfortune, your heart lights with hope that they will help save you and your parents from this nightmare. But no, it was all just a Hope Spot, since now the authorities have encountered the SCP which has ensnared their affections just like your parents. And now, with no other hope left, you watch as all your family and caretakers succumb to starvation, disease, or fights to the death as they neglect their own well-being as well as yours attempting to care for their new "baby". In other worse, a lethal and humanoid version of the cuckoo, or Debo Kyawaeen.
  • SCP-1100. It's a substance that mutates life. How is that any different from similar items? Well, it started by only mutating plants into forms that were hostile to humans and/or poisonous. Then it adapted to mutate animals as well. When presented with a choice of attacking a prey animal or a human, the human is always targeted. It can affect plants, wild animals livestock and even pets. It's implied that the Earth itself is creating the substance.
  • SCP-1178 is an ICBM that floats above a former Soviet base. Should anything get too close to it or broadcasts be made too close, the missile will accelerate and trigger any nuclear capable nation's early warning systems to make them think that there was an exchange and in turn, could actually cause an exchange and subsequent Planetary Class 2 Apocalypse How.
  • SCP-1237 is a brain wave that occurs in some people, causing them to go into a deeper-than-REM-sleep state. It causes the person to experience dreams that are not really any different from other dreams. The kicker, though, is that whatever occurs in the dream becomes reality. That's right, it's literally a reality warping dream. Some examples of effects from 1237-sleep include people changing gender, significant changes to city layouts, people losing or regrowing limbs, people gaining super powers, and governments being changed. The scary part is anyone involved in the dream will simply see the changes as normal, but will still have memories from before the change (imagine remembering two different things and believing that both are true, even when you know they simply can't be). However, the memories of people not involved in the dream will be unaffected, meaning they could get up one morning and be in a city they don't recognize with a new government regime they know nothing about. And absolutely none of it is under the dreamer's control. And since this is a brainwave we're talking about, the Foundation can't contain so much as limit its influence and mind-wipe everyone affected with class omega amnesiacs. And the dreamers themselves? They're taken by the Foundation and constantly mind-wiped to stop them from forming memories and never allowed to enter REM sleep again.
    • Many of you are no doubt wondering "what if a lucid dreamer was born with 1237?" There is only one instance of this happening. Like every other thing in the Foundation's storage it was attempted to be used on 682. A breakout was staged for 682 in an attempt to minimize casualties. Only one dozen security personnel were killed, making this part of the plan successful. Next subject 1237-1 was told of the breakout and ordered to dream that 682 was turned into a calico kitten in the process and brutally killed by machine gun fire. When 1237-1 entered R.E.M. Sleep, he began thrashing and screaming, before dying of what was termed a brain hemmorage. 682 was noted to have been covered in fur which withdrew in four hours. 1237-1's corpse was noted to be covered in scratches and black cat fur was found in his cranial cavity.
    • The really horrifying thing about it is that SCP's "containment procedures" for it include genocide of populations where the gene resulting in it is marginally (i.e.: 1-2% rather than 0.1-1%) more common than the human norm. They're not even looking for a way to neutralize it, such as gene therapy; they're just engaged in killing off anything from thousands to millions of people because they might have a slightly higher chance of being susceptible to it.
  • SCP-1548. 'The Hateful Star.' It's sentient, intends to destroy us all, knows we know about it and is coming closer. And worst of all, there is nothing whatsoever the Foundation can do about it.
    "I wake/I see all/And find it lacking"
  • SCP-1875 is a chess computer that comes with an engine with a timer that has its maximum setting worn out, a 32-piece chess set made out of human bone (sorta creepy), and a suit of samurai armor presumed to be used for performances involving the computer. The computer also affects other computers, in one case sending a memetic image, of two girls in black and white playing chess, that causes insanity. By the way, SCP-1875 also altered its own file, corrupting two incident reports and putting a possibly memetic file in the last one.
    • Not to mention what's actually powering the computer. It's the brain matter of a Russian chess champion's two daughters, apparently still alive and somewhat conscious. The odd glitches at maximum power and Brown Note emails suddenly make a lot more sense.
    • And for the love of god, DO NOT CLICK ON THE 3RD AND FOURTH ADDENDUMS. There is nothing you can do to stop seeing that... picture, except refreshing the page, which removes it.
      • The picture is downright cruel it is in its implementation. It's not animated, but the thing is, it comes after several pages of nothing but "UPLOADING... UPLOADING... UPLOADING..." repeated over and over - so naturally you'll scroll down faster to get through the textwall quicker, and end up with a faceful of oh God little demon girls before you're ready for it.
      • There's also the line of code in one corrupted report, "WE C Y0U, TITLE" surrounded by a double-%. Not a huge deal, right? Problem is, that TITLE code in wikidot code doesn't show the page title, but your username. The girls know you're looking at them. Not the Foundation, YOU.
      • To make things even more fun, it's implied that they've infected your computer. Oh, and that picture has nasty memetic effects which you will be suffering from shortly. Feeling a little uncomfortable after seeing it?
  • SCP-1981. Holy. Crap. Just try watching any political speech after reading that. It's a Betamax Tape of Ronald Reagan giving his "Evil Empire" Speech with a figure wearing what looks like a black KKK robe in the background. Over time the speech devolves into a series of highly deranged non-sequiters, delving into cannibalism, child molestation, genocide, and many other disturbing topics as Reagan is injured horribly, including by decapitation, impalement, and genital mutilation. His speeches often predict future events such as including the line "We will stop al-Qaeda" in 1983. Also, every one of his speeches includes the line "Now there you go again". And even if he's injured past the point of death, he doesn't stop talking. Did we mention the part about the tape changing the speech, the injuries, and the topics with each time it's viewed, or the part where the tape is alive?
    • Since Reagan was still alive, but not president anymore at the time SCP-1981 was discovered, the foundation launched an investigation to see if he had anything to do with it. It's implied that they showed it to him and erased his memory afterward.
      "No known connection was developed, though Reagan would frequently complain about "nightmares" before his mental state degenerated due to Alzheimer's."
    • And to make matters worse? It sees you.
  • The background "music" from the SCP-087-B game. This has to be the most spine-chilling, paranoia-inducing track in video game history.* SCP-1983 is a farmhouse that has a set of containment procedures pre-written by an unfortunate Agent who became trapped in it. The classification reads "Keter, God help you", and the Special Containment Procedures read "You're going to die, you poor dumb fuck."
    • Fortunately, it seems that a D-class was able to neutralize the farmhouse and was posthumously awarded the Foundation star. Unfortuanetly, the farmhouse isn't the only instance of SCP-1983.
    • Here's some snippets:
      • "You've probably tried going back out the door, but if you haven't, don't. It leads to some place even worse. There aren't any monsters, but… Jones went too far from the house, and I swear to God, he started to melt. Things started popping out of him, and… All you need to know is he didn't make it back. That's when we closed the door."
      • "There's also bits that are made out of… stuff. It's black, like the shadow-things, and it's mostly in the well-lit places. If the lights go out, you can stick your hand through. I don't recommend it. That's how we lost Torres. Something grabbed him, pulled him through. The hole wasn't big enough for his head, but he still went through, eventually."
      • "There were shadows in the place. I don't mean the monsters, I mean real shadows, of people. Only there was no one there to cast them. They were coming from the hearts. A new one appeared at the same time as the hatching monster, and started trying to pull away, but it couldn't."
      • "If you can, go in and destroy the nest. Destroy every last heart. If you do, maybe it'll kill them. It's the only thing I can think of. You'll probably die doing it, but you're dead anyway. So what's it matter to you how it happens?... Good luck. Morituri te salutant. (translation from Latin: We who are dead salute you.)"
  • SCP-1300, a dentist's chair that, for reasons unknown, puts people to sleep and inserts tubes that liquify and absorb foreign objects to the body (such as implanted organs, tumors, and even false teeth) and replaces them with a substitute that usually functions the same. Sound alright? Sometimes it randomly enters "beta-state", when instead of replacing foreign objects, it liquifies EVERYTHING inside you and steals it, filling you up instead with "biomatter" that invariably kills you. In a few instances, subjects even burst open due to too much biomatter being applied.
  • Although not as sanity-breaking as the other SCPs, SCP-1725 still rates high in Body Horror as each of its nine settings mutates the body parts of anyone nearby into mimicking fashion accessories, including fleshy shoe heels and dangling earring growths.
  • SCP-1227 was the result of a 1960 Russian social experiment where political prisoners were placed in an unlit cave with little food and water to study group dynamics under severe stress. After much torture, rape, screaming, muttering and one forced abortion, what was discovered was one of the male prisoners attached to a large lump of rotting, liquified human flesh revealed to be the remains of the other prisoners. It gets worse from there.
  • SCP-1147, a plum tree that can grow in anything and will take on the physical attributes of whatever it was grown in. Some of the test logs are funny, but the "Animalia Test Log" entries are just squicky or horrifying.
    • When they grew it in ground beef, the bark was muscle with a thin layer of cow hair and hair instead of leaves. The flower buds were "fleshy sacs" that smelled rotten. When the fruit was eaten raw, the consumers suffered from food poisoning-like symptoms. Cooking the fruit prevented sickness, but the taste was still described as "gross" and "wrong."
    • And then they had the brilliant idea of growing one specimen of 1147 from the brain of a D-Class. When the researchers tried to remove a fruit, the tree [DATA EXPUNGED] and required two MTF agents to bring it under control.
    Notes: Further testing requires O5-█ approval. Not that it'll do Researcher Paulsen any good. I accept full responsibility for not taking his suspicions more seriously. Dammit. I went into botany to avoid this sort of thing. -Dr. Laurel
  • SCP-1173 is a memetic hazard centered around a fictional country known as "The Islamic Union of Eastern Samothrace." Hearing the trigger phrasenote  infects you, causing you to constantly see references to this place, its people, and its history, and accept them as fact. The Foundation's tests discovered that some people with schizophrenia actually have memories of participating in military action in Samothrace, having been traumatized by atrocities that never happened. OR SCP-1173 is a memetic hazard that expunges all memory of the very real Islamic Union of Eastern Samothrace. Infected individuals exposed to the trigger phrase are purged of SCP-1173's influence. When in the presence of refugees from Samothrace, the infected will become violent, screaming "You can't be real!" Afterwards, they have no idea what provoked them. The worst part is, half the Foundation is infected, up to and including the O5. They're engaged in a cold war, and we have no idea who is right.
  • SCP-1425. It appears to be a New Age spiritualist self-help book from the Church of Happyology. But then we get to the chapter "Do Not Look Away From The Book", which includes such lines as "Some helpful advice that will save you in your coming weeks:" and "Love the archons. When you hate them, they see you." By Chapter 10 ("You Cannot Wake Up") the book has become pure Black Speech. Did we mention reading it brainwashes people and drives them crazy? Or that it can alter reality (and not in a good way)? And that the Foundation had to use Laser-Guided Amnesia on the entire Earth again? And then there's the intercepted broadcasts. Anyone think Peppy was going to introduce SCP-993 (see above)? And how about that American Idol broadcast? AND WHERE DID THAT HAND COME FROM?
  • SCP-1440. Wherever he goes, any trace of human society he comes into contact with will attempt to destroy itself, and his unknown compulsion to wander the earth brings him into contact with society very often. Problem is, he knows that it's all because of him and wants to be killed... but a side-effect of his power makes him effectively immortal. He approached an SCP agent hoping that the Foundation could find a way to destroy him, and since that time, he's managed to annihilate every single site that tried to contain him (at least five). It's gotten to the point that the Foundation has pretty much said "screw it" and stopped trying. He's still out there in the world somewhere, and the Foundation has no idea where he is...
    • He also has some advice for the scientist interviewing him:
    SCP-1440: Should you choose to challenge Death to a game of cards for your life, there is one thing you must never do.
    Doctor: And what is that?
    SCP-1440: Win.
  • SCP-1733 is a recording of a 2010-2011 NBA match between the Boston Celtics and Miami Heat. The catch is that with each new viewing of the recording, the events of the match changes with the people in the recording eventually become self-aware of their situation (although not yet to the extent that they are in a TV recording) to the point that viewings of the recording have been banned by the Foundation. The 27th playback shows the commentators are self-aware, the 44th-45th involves the players and audience, the first violence occurs in the 51st, a death in the 52nd, and by the 65th, three organizations have formed - one of which is a growing Religion of Evil, leading to the ritual-based murders of the teams' key players to appease whatever is causing the phenomena. The last viewing involved the possible sacrifice of children.
  • There are some bizarre things in the SCP Foundation's canon. SCP-1782 manages to be a massive Mind Screw even by those standards. The old man feeding himself to parrots may be the least disturbing thing in this room. "Testing subjects in all cases return from the interior of the room with a fear of holes. Exact reasons for this are unknown." And then there's the things the old man with the parrots says like "And then I'll be eaten. There's a hole in the wall in the bottom of the floor.", "Pour all the rest of the blood thereof at the foot of the altar, chickadees. In the hole in the floor." and "There's an abortion under the floorboards, one in the sink, too." What makes it even worse is that a hole that was never there, does indeed manifest later on. And it does in fact have an aborted fetus inside. AND IT'S STILL ALIVE! The underlying concept is amazing. It's all a manifestation created by an aborted reality bender. Which apparently holds a grudge towards its mother. And has a penchant to placing itself inside any woman around the area.
  • SCP-1893 is a mysterious entity that rewrites any information written about it into an unrelated fictional narrative, with the original document's contents given out in the from of dialogue. The common element of the stories is a violent and sadistic man with tattoos of bull horns on his face, nicknamed 'the minotaur', who carries a baseball bat. If you have an SCP Foundation account and are logged in, the text will call you out and threaten you with your username.
  • SCP-1958, the space microbus. Congratulations to its crew for being the first humans in space! Off to Alpha Centauri! Whoops, looks like the crew forgot that Alpha Centauri is 4.3 light years away, and the van can barely even top 130 kilometers per hour.note  By the time the remaining crew realized their mistake, only two out of four remained and were dying of scurvy. Now consider that the file mentions a missing person report for the driver; he and his friends most likely have friends and family back home wondering what happened to them...
    • Oh, and it turns out that one of them was a member of the Fifth Church. You know, the ones behind SCP-1425?
  • SCP-1155, a piece of street artwork that's alive, aware, and compels people to look closely at it so it can eat them, after tearing off eyes, tongue, hands and feet, and reappear elsewhere in the same city, if not another, and start again. And if you survive? It starts looking for you specifically. It also has a larder where it keeps his victims for later consumption, and it's been showing up in less abandoned places each time, including a playground.
  • SCP-1897 is a Deconstruction of the very concept of domestication. It's aliens that consider us the same way we do dogs, kidnap people, and then castrate them and leave them with the intelligence of dogs, treating them as pets.
  • SCP-1555 seems harmless enough at first: an industrial facility built into a mountain, with one long barrel that randomly launches containers of perfectly normal mice into a nearby field, where they run off unharmed (most of the time, anyway - there have been instances of dead mice, abnormal mice, and sometimes something other than mice altogether). But reading the audio/telemetry log makes it much creepier as a team goes inside to investigate. It ends on a horrifying note as the last surviving team member, following his tether to go back the way he came, finds that his line now inexplicably leads into a tiny pipe. He commits suicide, while up above the line retrieved by the base team is many times longer than when it was originally extended.
  • SCP-1128 is an aquatic monster that attacks people who know the full description of its appearence... and it can pull people into its world through any body of water that they can be fully immersed in, regardless of depth.
    • The good news is that if you survive the Foundation can cure you of its infection by giving you class-C amnesiacs, as the Mind Virus only works if you remember what it looks like.
  • SCP-1165, Glitch City in real life. Among all the other creepy things: if you're careless while exploring, you can suddenly find yourself in an infinite void where you're falling, forever, until you expire. The article mentions an entire large group of civilians who apparently vanished without a trace in the place. If you think that falling forever while you're alone is scary, imagine falling through void endlessly with a bunch of other panicked victims around you, presumably with people slowly starving to death and dying in mid-air one by one over the course of the weeks that follow.
  • SCP-1715 is an entity that exists on online communities, such as a forum. It will manifest as a user, and starts working its way up the forum. When it is high enough, it will send private messages to other site members requesting personal information. If they reply that message, they will die in the next two weeks. However, their user will still be active like they are still using it. Now, what if it is on the SCP wiki? What if it is on the TV tropes forum? What if everyone on the forum is dead and you don't know it?
  • SCP-1984. Thought the Dead-Hand system the Russians had during the Cold War was just computers? Well, no. It's actually a ghostly entity, who listens in to any radio and TV broadcasts made, and in case it hears anything that could possibly misconstrued as a future offensive, rushes to any missile silo around and launches absolutely everything inside, then keeps going with every missile that might be left in the entire damn country. It also moves insanely fast, can only be temporarily stunned by using microwave weaponry, and if you get between it and a missile, it will fry your brain so hard it'll leak out your nose. That's not much of an exaggeration.
    • The maker's log makes it even worse: They specifically looked for the most sociopathic Spetznaz officer possible, as they needed a man that could see the nukes falling, the world half dying, and press the button to kill off whoever might ever survive, and, in his words, "sign the death warrant of the human race".
  • SCP-1004, aka "Factory Porn". It's a disc that contains a program that allows you to see pornography of any subject; Rules 34 and 36 in .exe format, if you will. However, as one uses the program more, they will seek out increasingly Squicky fetishes, such as pedophilia, scat, and snuff, and it becomes harder for them to get turned on, to the point where the user will attempt to act out these newfound fetishes in real life. It's such a problem that a researcher who got infected tries to get two D-Class personnel to have sex for his pleasure; as a result, researchers are no longer allowed to look at the output of SCP-1004, even indirectly.
  • SCP-1372, a spatial anomaly that screws up several hundred miles of ocean, making it seem like it has an edge. Not only that, you can sail over that edge, and fall into whatever the hell it is that lies beyond it. The worst part? Sometimes they return, sailing normally despite being so damaged they should sink. And that's not getting into what happens to the crew. Details are spared, but to put it shortly: If one of them tries to tell you anything about what they saw, don't listen. And don't think flying over it can save you either. The exact same thing will happen, with the added detail that planes have radios.
  • SCP-1034, a small suture. While safe if left alone, if anyone makes contact with it they begin using the suture to sow up their facial orifices, starting with the mouth and moving onto the eyes, nostrils, and ears. During this process, the subject loses all control of their body except for their facial muscles, lungs, and vocal cords. After all orifices have been sown, the subject will just stand there and rapidly dehydrate until they are a leathery corpse. The worst part of this? During the sowing process, the subject is completely awake and aware of whats going on, with the threading of their mouth being just loose enough for them to breath. This means the only thing the subject can do is scream.
  • SCP-1353, little felt centipedes that burrow inside you while you sleep and make their home in there. For the most part they remain dormant and harmless, but as soon as you get a feeling of nostalgia, they wake up and start crawling around... and you can feel every bit of it. The addendum at the end then proceeds to describe this in vivid detail. Good luck sleeping after reading that.
  • SCP-1575. It is a statue/fountain that, over the course of about a month, slowly transforms animals into humans when they drink from it. What sounds like a furry fetishist's dream quickly becomes a nightmare when the Foundation does what it does best and injects some cruel reality into the concept; simply put, animals and humans are biologically different for a reason. Only three tested animals managed to survive the transformation and only one of those three transformed fully with no unwanted results. The rest feature such lovely imagery as a field mouse whose cardiovascular system shut down because it couldn't keep up with the rate her body was growing, a tiger whose organs failed after just four days because of the sedatives she was given, a parrot whose skeleton shattered in various places because, like the field mouse, it couldn't keep up with the rest of her (her wings did apparently manage to form a set of pseudo-hands, though) and most horrifyingly of all, a dog that was not properly checked for parasites before her transformation. The parasites were also affected by the water and...well...
    Dr. ████: We absolutely do not need another instance of half-mutated flea-creatures, and the psychologist is having a hard time helping Janet with her nightmares of a seven foot long tapeworm with a screaming face tearing out of the belly of a dog.
  • SCP-1738 is a barber's chair that puts anyone who sits on it into a coma. When they wake up, said victims experience intense phobias towards specific things. The creators responsible were themselves exposed to SCP-1738, with one suffering intense hallucinations of being abused by his mother, despite his mother dying at childbirth, and another completely catatonic despite having no direct exposure to the chair. Originally in the hands of Marshall, Carter, and Dark, a note left revealed that clients intentionally subjected themselves to SCP-1738's effects. That's right, they deliberately made themselves experience their worst terrors simply for the sake of getting a fear-induced high.
  • SCP-1282 are five rabbits (rendered sterile after containment) who turn into human hunters, complete with weapons and gunpowder, during the coming off the full moon. During this time they hunt and eat any rabbit they previously lived with, including mates and children. They continue doing this until all rabbits in the area are killed or the lunar cycle ends. Considering this is done with rabbits, this may not be as nightmare-inducing as the other examples above. However, the page notes that after the transformation SCP-1282 exhibit depressed behavior, refusing to move or consume food. This is both horrifying and a massive Tearjerker as it is implied that the rabbits have enough awareness to lapse into a depression at the death of their offspring and mates done by their own hand.
  • SCP-1269, a sentient mailbox that develops stalkerish tendencies when a woman in her twenties or older moves into its house. At first, it's kind of Black Comedy and definite Refuge in Audacity (seriously, a stalker mailbox!?) with his constant love letters that basically come from nowhere and get more and more erratic as time goes on and destroying any mailbox that dares to get in the way of him and his "beloved"...then it gets creepy when it's revealed that the mailbox will occasionally teleport to the occupant of the house when he wants to and follow her around...and then it gets terrifying when it's revealed that he kills a human male who moves into the house with the occupant.
  • SCP-1127 is a series of short films that permanently alters their viewers' minds. In order, we have:
    • "Were Clowns Always Yellow?", in which a Nazi clown that narrates how people's lives become jokes, with the affect being that anyone who views it starts seeing morbid things funny and funny things unfunny.
    • "Crazy Where? You Are", in which a little girl narrates over clips of graphic violence about how said violence is "the only answer" while stabbing a teddy bear. This leads viewers of the thing to become violent sociopaths.
    • "All? Comes With Yesterday", in which a woman in Victorian clothing and a mask sewn onto her face narrates over images of technology and just recites random words, at one point repeating the word "liar" over and over. Anyone who views this one becomes terrified of anything man made, especially technology.
    • And lastly "Why Are You Crying?", in which a leatherman narrates over pornography and other sexually explicit images in a creepy fashion. It causes anyone who sees it to grow obsessed with different creepy paraphilias.
  • SCP-1057. It's shaped like a shark, it behaves like a shark, it eats like a shark, and it even has the anatomy of a shark. Except it's not a shark. It's an animate blank space in the shape of a shark. In other words, it's galeophobia brought to life.
  • SCP-1812 isn't too scary on its own. It's an unusually dense asteroid in a retrograde orbit 180 kilometers above the Earth with no danger of collision. It's basically an extra moon...but you won't notice it until you see a picture or someone who has already seen it points it out to you. Once someone has been made aware of it, they'll be subjected to its effects. This includes perception of things such as extra reflected light during its lunar phases, an increase in global volcanism, and a tide that covers 85% of the Earth's islands and coastlines. People under its influence can appear to swim and even drown on dry land, as well as burn in nonexistent lava flows. The Foundation isn't even certain if SCP-1812 actually exists.
    • It is possible to counteract the memetic influence and convince affected individuals the tides and SCP-1812 aren't real. Except they also lose the ability to perceive liquid water and stellar light (including that of the sun) as a result.
    • The Foundation learned of SCP-1812 from the journal of an amateur astronomer named Alexander Montag. Shortly after his discovery, he barricaded himself on a roof, believing New York had been engulfed by a tidal surge and that everyone he was seeing were just hallucinations. He died after trying to escape the roof in a makeshift boat.
    "The Foundation began investigating the incident when it was found Mr. Montag had survived the fall, and had died from suffocation and hypoxia. Agents recovered Mr. Montag's journal, which contained all information currently known about SCP-1812, and serves as the primary vector for the meme. It is currently unknown how Mr. Montag discovered SCP-1812 without any prior information regarding it."
  • SCP-1739 is a laptop that either creates another universe or sends the user into one. Some time afterwards, the entire other world undergoes something that is beyond heat death. Now, what if our world was one of these realities that the laptop creates?
  • SCP-1238 is a species of unclassified deep-sea fish which gains the ability to eat minerals and inorganic matter for three months out of the year. Not that scary, right? Well, they use this ability to dig their burrows, which they keep expanding on throughout their lives. Since their population explosion in 1850, they've built a vast tunnel system running beneath most of the Pacific Northwest. The article has a nicely detailed scenario for Event 638-Mu-34, the collapse of the whole network: most of Washington, Oregon, and Northern California sinking, a huge tsunami spreading across the Pacific, the global sea level falling several meters, millions of people dying, countless species going extinct, the water becoming contaminated with chemical and nuclear waste, and a resulting famine from the loss of land. All of this would likely result in an IK-class civilization collapse scenario. There's not much the Foundation can do besides thin SCP-1238's numbers and slowly move people out while searching for a better solution. Event 638-Mu-34 is predicted to happen sometime in the next few decades.
  • While instances of SCP-1795 themselves aren't terrifying (in fact, their article is mostly one long Crowning Moment of Heartwarming), one of their transmissions mentions a war and something called the Pattern Screamer. We're given no description of it, but whatever it was, it caused a galaxy-wide genocide of humanity and forced them to retreat to remote corners of the Milky Way, like Earth. It was so thorough that the Star Wombs weren't even aware if any of their masters survived, which is why they've been building planets in the first place. What if it's still out there right now?
    • The Pattern Screamer is mentionned by other SC Ps. And always in a worried/terrified way. Whatever it is, it must be really nasty...
  • SCP-1506 is a behavior pattern in spiders that makes them cooperative colonies that create floating cities. They also change how they hunt, shifting from insects to large mammals, dangling down spider webs that paralyze them and then drag them up at high speeds. This has captured jet liners on accident. What's worse is that it is suggested that this is simply a learned behavior: every spider that escapes the colony can form more colonies.

    SCPs from 2000 to 2999 
  • SCP-2000. Right from the get go, you know this is something big when you see they've got an cognitohazard safeguard, just like the SCP-001 page. Then you see its classification: Thaumiel. Essentially, it is a huge facility capable of cloning the entirety of the human race in the event of an end-of-the-world scenario, able to set the culture and civilization of mankind to any time period chosen, with politically important figures copied exactly to get the world running back on track. It is an enormous Reset Button. The scary part is it has already been pressed who knows how many times. A corpse found in it is dated back 450-700 years, and a letter accompanying it indicates that it was around long before then. Attached notes also indicate that we've still screwed it up by rewinding too far before its repopulation began, which ended up causing World War II. One note even says that they will not try reducing humanity's violent and sociopathic tendencies, because they already did, successfully.
    • If this sounds familiar, it's because this is likely the origin of the "Document Recovered From the Marianas Trench".
    • And another thing. That corpse? It's Doctor Clef's. Yes, the doctor's walking around fine, and has absolutely no idea why there's a centuries-old corpse that matches his DNA, and yet there it is, with a note marking that even he, and then, had absolutely no idea when, and for what, they built the facility.
  • SCP-2950 is referred to explicitly as "Just A Chair", with no real harmful side effects except the fact it is so comfortable, force must be used to remove from the chair any person that sits on it longer than half an hour to an hour. It is classed as a "safe" object. Kind of creepy that a simple chair could mess with your head like that, right? [[spoiler:Then you read the addendum, intended for a single O5 only, which reveals that they want people to think 2950 is a "safe" object. It's actually a Keter-class object that is capable of bringing about an XK-class scenario. It is "undefinable", only defined by what people think it is. If the Foundation can convince people it's just a relatively harmless chair with a creepy effect on people, that is what it will be. The problem is, there's a book written about 2950 saying it's a world-ending monster, that appeared in The Wanderer's Library, leading everyone, even the Foundation, to believe that was what it was - it was even contained as its "monster form" for a long time. The Foundation had to communicate with the Serpent's Hand to be convinced it was in fact an "undefined" object that is only what people choose to define it as. The most disturbing part, of course, is that this means someone defined 2950 as a world-ending monster on purpose, possibly just For the Evulz, and word must never get out that it is anything more than Just A Chair.
  • SCP-2317, "A Door To Another World"'s page contains 6 tabs, each a record of a different SCP staff member logging in to the database to read the SCP entry, each with increasing security clearance that reveals more and more sensitive information. The first iteration, a lowly staff assistant, gets almost no information at all, other than that it's a wooden door frame which leads to another world, kept in security by the Foundation. Then a security specialist finds out that it's Keter and more about the containment procedures, including something called "Procedure 220-Calabasas". An assistant researcher finds out more about the nature of the SCP and potential consequences for failing to perform the containment procedure- a potential XK-Class End of the World scenario. A senior researcher gets most of the details of Procedure 220-Calabasas, which now requires a high-clearance foundation staff member pretending to be a Class D and some form of ritual sacrifice. Dr Crow himself reveals the true nature of the threat: an immensely titanic entity, estimated at over 200km in height, imprisoned below the ritual site by 7 colossal chains- 6 of which have already broken. However, it does slightly alleviate the horror by also revealing that the sacrifice required daily is only a chicken. But, the worst is yet to come..
    The 05-restricted entry reveals that, while the description of the world beyond the door and the imprisoned entity are accurate, the rest of the entry is a complete lie. The SCP? Not the portal, but the entity imprisoned beyond it itself, a creature referred to as "the Devourer of Worlds". Its true designation? Apollyon. The meaning of that? The Foundation is utterly powerless to do anything about it. The containment procedures? "Irrelevant." While the Foundation is desperately trying to find a way to contain the Devourer when it inevitably breaks free sometime within the next century, at the moment they're at a loss to either repair or replace the broken chains or prevent the last one from breaking. All the hoo-ha and fuss about "Procedure 220-Calabasas" earlier in the document? A smokescreen the 05s have implemented to prevent panic by convincing people that they're achieveing something meaningful. In short? We're effectively doomed and the SCP Foundation can't save us!
  • SCP-2003 is a straight-up time machine used by the Foundation to find out about possible futures and guide humanity onto the correct path. The method used is pretty horrific in itself (only brain and nervous tissue survives time travel intact, so travellers must be 'prepared' suitably) but that's not the scary part. There's a memo explaining that the Foundation is using all its resources to try to keep the timeline on-course for a particular future designated XN. What happens in scenario XN? In 2349, an asteroid hits the Earth, wiping out most of humanity and rendering the planet uninhabitable. Of all the possible futures the Foundation has encountered, this is the best outcome.
    • The real kicker? It IS the best outcome, in the sense that its the only one the Foundation has observed where humanity survives the first century of the 2000's. In ALL other timelines so far observed, total extinction occurs anywhere between 10 to 50 years from present day from a wide variety of causes, from our Sun spontaneously transforming into a black hole which not only freezes our solar system but somehow leaves all of humanity in a state of suspended animation, to all life on Earth mysteriously disappearing overnight aftr a period of extended world peace, to a breed of mind controlling spider taking over 85% of the population and forces them to breed more of them, which eventually leads to the death of 6 billion.
  • SCP-2999, while the article itself isn't overtly scary, just a little unsettling (and MORE than a little heartbreaking), the page image makes for a great scare. The first page image is the desktop that SCP-2999-A uses. It prominently features some kind of disturbing half-human half-rabbit hybrid with large black eyes and a blood covered mouth. Clicking to enlarge the image doesn't do much expect that it reveals the image to be animated, showing the desktop very quickly change to a horrifying image of a dark rabbit-like humanoid abomination standing in a darkened blood covered room, before reverting back to the original desktop image.
  • SCP-2998. Like SCP-2317, the article is broken up into multiple revised versions. SCP-2998 is a radio signal whose source is unknown, but has been picked up from all over the Solar System. It was thought to just be strange but harmless white noise until technology to decode it was developed in 2011. The signal contains a video transmission of a humanoid alien floating in a dark room, making sounds and gestures like it's in physical distress. No context is provided. Later iterations reveal humans born with a rare nerve cluster in their Temporal lobe can decode the signal, with some side effects, and have discovered what the video is: a criminal named Ruhar being punished by an all-powerful ruler named Adidal for killing a member of the latter's family, doomed to be kept alive and suffer on public broadcast until the universe grows dark.
    • Another iteration reveals that on 11/09/14, all Rosetta Cluster D-class personnel exposed to SCP-2998 experienced seizures, while the alien in the video fell unconscious and the transmission ended. After months of inactivity, SCP-2998 was considered neutralized. Problem solved, right? Nope! In December 2016, an alien fleet approaches the Earth and begins transmitting a new form of SCP-2998 on all radio, TV, and satellite signals. Anyone who hears it falls under Adidal's control. The Foundation responds to this with Operation Blackout, destroying all global communications infrastructures and killing everyone affected. When interviewing a captured subject affected by the signal, they claim that Ruhar has disappeared and now they're looking for him, and reveal that the "aliens" are in fact living ideas. A later iteration implies that Ruhar may have taken control of a high-ranking member of the Foundation, and the remnants of the Foundation After the End are eventually forced to combine SCP-579 with SCP-055 to reset the universe.
  • SCP-2030 is a television series which consists of prank videos that spontaneously appears on streaming sites (and before the emergence of such sites, on stores as DV Ds and VHS). First, there's the fact that all the people seen in the audience or in the prank segments disappeared or died during the year the episode is released. Mysterious, but a bit tame. The real kicker, though, is that the pranks are supernatural, horrifying, disturbing and are complete mindfuck-fests. The most bizarre part is that, no matter how horrible and vomit-inducing the pranks are, the victims will laugh them off as soon as the show's host will reveal himself. And of course, the article describes some of those episodes...
  • SCP-2952 takes the concept of a long lost relative or creepy uncle/cousin and somehow makes it even more disturbing. The SCP is essentially a figure known only as "Cousin Johnny", who manifests at random family get-togethers such as Catholic masses, funerals, weddings and child baptisms. Whenever "Cousin Johnny" appears at one of these get-togethers, the events of said get-together become morbid, disgusting and violent and even possess dangerous consequences for the attendees later in life. Said events include allowing the bride and groom at weddings to smash each others teeth in who then proceed to feed each other the teeth, having a baptized infant's skin molt off which is then fed to its grandparents, and participants at funerals slitting their wrists over the open coffin while "Cousin Johnny" vomits dead bugs into it. During Black Level gatherings (which normally happen during funerals), The Foundation has no way of stopping said events from transpiring, only watching it from beginning to end with no way of preventing "Cousin Johnny" from spawning. What makes the whole thing scary is that no one who willingly attends these gatherings finds any of the events out of place, and treat "Cousin Johnny" as a welcomed family member. On top of that, reading the effects of each event level reveals that this thing has most likely killed or maimed thousands of people.
    • "Cousin Johnny" and the events surrounding him?/it? are all ultimately related to cicadas somehow. Children baptized in Blue Level events "molt" and later exhibit violent behavior and PTSD-like symptoms when they hear cicada cries, the groom produces a cicada call instead of vows and the couple is later presented 13 dead cicadas by "Johnny" himself in White Level events, and Black Level events have "Cousin Johnny"'s eulogy devolve into cicada song eventually, along with the aforementioned vomiting of cicada corpses. Why this is so is unknown, but it certainly won't help people who dislike the bugs to begin with sleep any easier.
  • SCP-2740 is probably one of the most disturbing examples of Nothing Is Scarier on the entire website. SCP-2740 is a strange entity believed to be residing in the attic of a Lee residence. According to the description and containment procedure, it is not known if the entity even exists, but the anomalous properties stem from how those who live in and around residence insist that it exists. What really sells the creep factor on this SCP is that attempting to enter the attic fails, not because the SCP blocks passage or puts up some sort of barrier but because person who attempts to enter just gives up or are unable to carry one up the ladder. Essentially, people who do so end up "waking up" at some point in the house, almost as though they had woken up from a day dream, though some individuals such as the wife insist they have entered the attic even when evidence says otherwise. Oh, and ignoring the entity won't help, as it gives off some sort of dread that gnaws at the psyche of the residence of the home. The husband of the house for example claims that whenever he tried to enter the attic to confront the entity, he would simply find himself unable to go up the ladder, to his irritation. Because of this phenomena, the foundation can't properly contain the entity, as personnel will simply believe they entered the attic when in reality they didn't. Even unmanned expeditions don't work!
    ...several attempts were made to penetrate the attic, both manned and unmanned. In all cases, further investigation revealed that no attempts were actually made, regardless of the claims made by involved personnel stating otherwise.
    • These attempts may have included direct access through the second floor attic ladder, shaped charges situated at various points on the second floor ceiling, drone access through the ladder opening, manned and unmanned access by cutting through the roof, and complete leveling of the home. As stated above, no records exist that any of these methods were actually attempted.
    • Oh, and the Lee family can't leave their home. Whenever they try to move away, the affects that manifest when they try to enter the attic happen when they try to exit the house. They are trapped in a house with an entity that may or may not even exist.
    • Even more bizarrely, they interview Olivia Lee, the daughter of the family that's constantly alluded to, and she's apparently changed her name to Rebecca Feldman. But, by the end, investigation reveals that Olivia doesn't exist. If so... what was Olivia? How did the Foundation interview Rebecca Feldman? If they did... What happened?
  • SCP-2151 is a pair of rings that fuse the two people wearing them together, in a process that's described with marvelous detail. And then there's the addendum, explaining the circumstances of the object's retrieval.
  • SCP-2059. Some kind of amorphous mass of body tissue, which will assimilate any living creature that touches it, minus keratinous materials like skin and hair. It currently consists of a blue whale, a giant squid, a pair of dolphins, three hundred rodents, several specimens of livestock and pets, thirty-one humans, and an unknown number of insects. The weird thing is that 85% of the assimilated organs are just sitting there, inactive. Also, not only is SCP-2059 fully sentient, but consists of two separate intelligences: a Buddhist man who has retained some of his individuality and an entity referred to as "the child." At one point, the Buddhist was able to communicate with a Foundation scientist by using SCP-2059's biomass to form a new face. According to him, the child comes from a different place with different rules, which the Buddhist refers to as the "third cycle of (UNINTELLIGIBLE)." He has little understanding of things like a heart and liver, which is why most of the organs in SCP-2059 are inactive. This seems to imply that he may actually be absorbing life against his own will. The page also has a picture of part of the thing. Viscera and all, including an eye of the giant squid and what looks like a aforementioned face.
  • SCP-2006. At first, it doesn't seem so bad. It's a shape-shifting entity that seeks to scare people For the Lulz, but is otherwise friendly and cooperative. It's also not really that scary, usually taking the form of Ro-Man and jumping out at people with cheesy lines. Even so, all personnel have to act terrified of it and continually remind SCP-2006 that it's the master of horror. Why? Not only does it have limitless shape-shifting abilities, but it's completely indestructible and always searches for new ways to scare people. The only reason it takes such Narmy forms is because the Foundation takes advantage of its poor understanding of human emotion by only showing it low budget horror and sci-fi movies. If SCP-2006 were to breach containment, it could discover what really scares people.
  • SCP-2872 is a horse that runs in circles at speeds high enough to smash through anything in its path. Seems like standard SCP material, right? Until you read that sometime after 2010, it launched from its containment cell fast enough to cause injuries in the triple digits and achieve orbital escape velocity toward the constellation Equuleus. At the time of the entry's writing, it's slowing down. And it's turning around.
  • SCP-2932 is a giant dome made entirely of trees, vines, and other plant matter located in a nature reserve in Peru. It's lit from within by bioluminescent structures, powered by a giant vascular organ in the middle of the main chamber, and protected by mobile plant-based organisms. The main section mostly consists of large rooms and arched hallways, with rooms in lower sections containing what used to be administrative offices. The only individual still living inside is SCP-2932-A, an elderly semi-humanoid insect creature. Deep beneath the surface, there's a massive chamber filled with a system of catwalks and plant pods, each with a small organic touchscreen that can open or close them. Some of these pods have been ruptured from the inside. Have you guessed what this place is? It's a prison built by SCP-1000 (yes, the Bigfoots) to house a variety of dangerous creatures and entities. During the human uprising, they evacuated and left a skeleton crew to maintain the prison. SCP-2932-A was their warden and is now the only survivor. As the years passed, and the structure fell into disrepair, some of the entities escaped. The entry also includes translated records of the prisoners, some of whom were humans that hunted the Bigfoots even before they acquired their technology, but also include a hungry beast that came "from the heavens" and something that the Bigfoots refused to describe. The final entry cements the idea that humans and Bigfoots truly are Not So Different.
  • SCP-2521 is a creature who steals every piece of information about itself, as long as the information is expressed in verbal mode. Because of that, everything about it is registered by ideograms and pics. Did we mention that people reading its report loud counts as "things that can be stolen" by this monster? And that the monster is impossible to contain?

    Foreign SCP Foundations 
  • It's a pity that the SCP from the foreign branches aren't translated, because they can bring the creepy. Some from the Spanish branch:
    • SCP-ES-045, a doll made of porcelain and... some kind... of human tissue. It makes people stay still, lose their communication skill, and then [DATA EXPUNGED]. The subjects do survive and get better, but get a reasonable fear of dolls after the experience. The doll was found in an abandoned house in a neighborhood after the disappearance of a number of children, which gives you a hint on how this thing was made. When in contention, a note from its creator appeared, promising the doll to rescue her. After a containment breach, which ended with the assigned personnel found with their tongue and several internal organs removed and dressed in baby clothes, another note from the creator was found, saying, more or less "I don't want you anymore. you're as evil as always. Also, I have new toys. Don't come back, or I'll tell Daddy". The thing is so vile, not even its creator wants it back.
    • SCP-ES-053, "Mother and ████", combines the unknowing aspect of SCP-579 with an inversion of 231. It consists of an ordinary woman in her thirties and an unknown number of [DATA EXPUNGED] (one of them being a cognito-danger of some sort) that only she is able to contain in their cell. It's implied that whatever she is containing has affected her, to the point that she has stopped collaborating with the Foundation, but the danger they present is so big they can't be terminated, and merely permitting them to leave the cell can have a massive effect in all the humans' psyche.
    • SCP-ES-020, a funerary urn from the Tonocoté aboriginals. When a person touches it, an humanoid entity with the appearance of an attractive native of the opposite gender invites them to know the wonders of their world, and uses the urn as a portal to a world where the pre-columbine cultures are still alive and blooming. If the person doesn't come back immediately, they begin to integrate to the new culture, up to the point of losing their ability of speak their mother language and instead adopting the local aboriginal language. After some level of integration, the person is offered to remain in that world; many of the subjects accept. All was fine and peachy, until a volunteered D-class discovered that some people invited to live in the world inside the urn was offered as human sacrifices and escaped to avoid that fate. The urn also wants to break contention, and from time to time arrows with poison come from it.
    • SCP-ES-088 a labyrinth that can manifest in any hotel or equivalent establishment. You can easily enter on it, barely without realizing that its decoration clashes with the rest of the hotel, until it was too late to come back. Inside of it there are miles and miles of corridors, with no doors and constant muzak. Also, human bodies, the corpses of the people who got lost there and weren't rescued on time. And still, those who died are way luckier than the guy that managed to find "the center"...
    • SCP-ES-019, the apocalyptic headphones. It's a pair of headphones that tune to transmissions from different scenarios of human extinction. The people who hear any of those begins to suffer either related PTSD or the physical effects of said scenarios. One of the described world-end scenarios involves the "Human Cattle Breeding project". Just do the math.
    • SCP-ES-061, the alternative VCR player is, in contrast, pretty harmless: just a VHS player that display the What Could Have Been version of whatever tape you play on it. Until you see that the O5 has forbidden its use with documentaries and non-fiction material after the (expunged) results obtained when played several documentaries, in particular one about the evolution of men.
    • SCP-ES-071 is a memetic agent that manifests as a writing in one of many indigenous language in the skin of any person that read its text from any written surface it was transcribed. The text is basically the address of some magical golden city with many riches, but the location differs in each language transcription. The person infected has also vivid mental images of the geographical accidents near the site, acquire the compulsion to go to said city, and the infection can be get even if the person doesn't know the language of the text, and every time they want to write it is in said aboriginal language. Fortunately, the memetic effect doesn't spread when said person repeats the content of said text in their mother, occidental language, but since by then the infected has lost their ability of write in anything that isn't the aboriginal language of the text they carry, that's isn't much of a consolation. As if the former wasn't already bad, the four demonstrated "addresses" are all sites specifically geared towards brutally killing all non-native Americans, and more specifically, Europeans. One of the places the text directs is the original location of SCP-ES-082, a Mayan sarcophagus who contains something who gleefully kills anyone of non-indigenous ascendant; another led to an Amazon site teeming with hostile natives who utterly despise foreigners, and a third points towards a Peruvian site filled with twelve of an unknown SCP that was already responsible for a mass grave. The last of the described places had its data expunged, save for the fact that the Foundation had to raze the pace with napalm and then irradiated until it was rendered unhabitable.
    • SCP-ES-027, the constantly mutating air ducts of a Venezuelan building, and the man-eating predator that lives in them. Another generic labyrinthine manifestation with attached homicidal being who can be contained by just sealing it, right? Except that isn't limited to that specific building: it can manifest in other buildings on the globe as their wish, and isn't just one creature. The containment procedures had to include feed them D-class personnel in the original building as a way to impede them to move away from their original location.
    • SCP-ES-015 are pills that are impossible to ingest. Literally. Trying to swallow one just chokes you. Powdering and dissolving it to drink it only accelerates the process. If you manage to introduce it on some living organism it will cause their death unless you extract the substance from their bodies. And every time, the substance will reform into their original pill form once they got out of the formerly living being. But the real disturbing thing is its backstory: apparently its creator developed what could be constructed as an improved version of SCP-500, so good it really gives you immortality; but a super-religious coworker decided that this was an heresy, so they tampered with the formula so no-one could ingest the substance ever.
    • SCP-ES-021: A horrifying inversion of Humanoid Abomination: a colossal creature that descended from the skies and slowly advanced until finally getting stuck in Taipei. It's resilient enough to tank various nukes, had an extremely developed Healing Factor, is monstrously powerful... and has the mind of a young, bright woman who doesn't understand or remember what has happened to her and wishes to harm nobody, even building graves for her victims and only lashing out when agents were harming said graves. In fact, its only wish is to be killed. Which, incidentally, much to the Foundation and the Coalition's distress, they can't do. They're trying everything. When they saw the nukes were ineffective, they tried to seal her in an unstable, collapsing universe. It did squat to her, to the point she remains stable. She's still stuck in place, immortal. They had to build a building around her to hide everything and keep trying and failing to kill her. And they have to keep trying, because otherwise she'll go mad again. Prognosis says the Foundation is likely to lose Taiwan entirely should she do that.
  • The French branch of the Foundation also has a few pieces of interest:
    • SCP-096-FR was a village populated by people who were all wearing masks and costumes... Badly made ones that launched them straight into the Uncanny Valley. Anybody who enters the village will be persuaded into staying and putting on one such costume. Eventually, they will have their minds rewritten so that they would think they had always inhabited the village. That's bad enough, but every Halloween, the villagers would leave their town and go trick-or-treating in the neighboring towns... And forcibly converting those who failed to give them candies. Fortunately, they had been neutralized by agents of the Foundation.
    • The proposal of Dr Johannes for SCP-001-FR is a failed experiment by the Foundation that caused the sudden apparition of some sort of corruption of the law of physics, something that causes an unstoppable imbalance and a growing disorder in the very way reality works. They decided to call this phenomenon entropy. That's right, the force that will inevitably cause the end of the Universe and the extinction of all life is a direct result of the Foundation fucking up, and didn't exist until then.
    • This also means that all scientific knowledge since its creation has been either distorted or completely fabricated according to the effects it has on the universe, including the Laws of Thermodynamics.
    • SCP-054-FR will cause nightmares to any aquaphobe. It's a phenomenon that only happens on the shore of some island, and which turns seawaves into jaws of great white sharks as soon as a potential victim comes near.
    • SCP-006-FR is a butcher that materializes along with his shop between other shops, without anybody seeing anything strange with this. Any non-vegetarian that enters the shop will order some piece of meat, and the butcher will happily provide it... But by some unknown way, he actually uses the customer's own flesh. Who then goes back to his house without even realizing that something is wrong (and without dying if the wound would normally be lethal) and eats his order, at which point he's freed from whatever was clouding his mind and dies from the blood loss.
    • SCP-185-FR is a few instances of what looks like oversized wind ornaments that materialized in a forest. They create a zone around them in which every single form of kinetic energy is nullified : everything trapped inside said zone is permanently « frozen » like a statue, without any hope of ever being rescued as anything that would try to get inside would fall victim to the effect. That's already bad. The worst part ? New instances keep popping up, each one increasing the area of effect. The Foundation hypothesizes that, sooner or later, the entire world will be affected.
    • SCP-075-FR is a mask that possesses whoever dons it and turns its victim into a feral creature. What's worse is that the mask is highly radioactive, so once its host is too damaged for wearing it, it will seek another victim and basically turn it into a walking nuclear hazard.
