''Please add new examples to the bottom of the page.''

* 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 assault 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.
** Nah, I think the crowning piece would be that little bit on that page about Tvtropes: "Human Resources is encouraged to draw upon personnel drawn from [[http://scp-wiki.wikidot.com/scp-4445-j SCP-4445-j]] in first-stage recruitment for personnel, D-Class or otherwise." Hello, future D-class personnel.
** No. The worst one are the ones that say something like "Due to the nature of this SCP, it cannot be contained."
* [[http://scp-wiki.wikidot.com/scp-583 SCP-583.]] Good luck watching SesameStreet again.
** I dunno, I think there'd be an upside to it. For example, I'd enjoy Fox News, Reality TV, etc. a lot more once I'd watched that tape.
* [[http://scp-wiki.wikidot.com/scp-280 SCP-280.]] It attacks people and rips them to shreds... for ''no reason.''
* [[http://scp-wiki.wikidot.com/scp-173 SCP 173]], the statue that tries to kill you if you break eye contact with it.
** Enlarge that page's picture to get a better idea. Enter the jibblies.
** 173 appears to be ''the only thing 682 is afraid of'', as when it was locked inside 173's chamber its first response was to huddle in the corner farthest from 173 and stare at it without blinking for several hours. When snipers popped 682's eyes from afar, it responded by growing bullet-proof eyes all over its body so that it could keep 173 from getting close to it.
** For extra nightmares, think on this: As long as you look at it, it's a harmless statue with entirely curved edges, no claws or anything, made of [[strike:papier mache and therefore probably very light]] concrete and rebar, so it shouldn't be able to move. So... what is it when you're not looking at it?
** Also: [[http://scp-wiki.wikidot.com/revised-entry this short story.]] What would happen if said statue replicated. Exponentially.
** Said entry describes 150 SCP-173s attacking and ripping apart ''SCP-682. The fucking indestructible lizard.''
** [[http://www.youtube.com/watch?v=UBLIAasOfxk This video]]. The statue in action.
** Seriously, [[BrainBleach its appearance is what makes it terrifying]].
** [[http://scp-wiki.wikidot.com/scp-232 SCP-232]] falls into a similar vein. It's a statue of a Sumerian goddess that will cut you up if you allow any shadows into its constantly-lit containment area.
** Also: [[http://scp-wiki.wikidot.com/scp-978-extended-test-logs When SCP-173's picture was taken with SCP-978,]] there was no change[[hottip:*:Pictures taken with SCP-978 show what the picture's subject wants to be doing at the time of the picture]]. Think about it. [[spoiler: SCP-173 ''is exactly where it wants to be''.]]
** Isn't being where it is now significantly better than the alternative? The Foundation can at least try to keep it contained while it's where it is.
** Or it just might not be sentient. Which may be worse, as that means it does what it does for no reason at all.
** Even non-sapient creatures like animals tend to show some kind of change when photographed with SCP-978. The most horrifying possibility of all is that SCP-173 is either not alive, or a living being that lacks any form of consciousness or will whatsoever, ''yet continues to kill!''
** Tropers, you seem to have forgotten about [[http://img822.imageshack.us/img822/4066/tblink.jpg this]] comic. NothingIsScarier until it's smiling on your face.
** They've tried [[WhatAnIdiot duplicating]] SCP-173 with SCP-038 (a tree that can copy anything short of two hundred pounds). The good news? It stopped short of two hundred pounds, so only the head, right arm and upper torso was copied, and it moves so slowly that they didn't notice it during testing. The bad news? It ''didn't stop moving'' when it was observed. This thing is supposed to be a perfect copy of the original; how could we stop it if it just decided to ignore its one supposed weakness?
** Perhaps SCP-173 is just [[spoiler: putting up an act of being able to move only when not observed. The clone could have either not come to the conclusion the original one did, or just attacked because it felt like that was its last resort.]] What's horrifying about this is the implication that SCP-173 could [[spoiler: attack anyone, at anytime, but it's just '''messing with you.''']]
** And worse, it sounds, suspiciously like [[{{Doctor Who}}another creature that moves when you don't look at it that is a statue...]]
** In the game "Containment Breach", you have to run away from it, among other SCPs. And if you encounter it, and you close a door in between SCP-173 and yourself? [[spoiler: It ''opens the fucking door'' and resumes chasing the player. There is literally ''no way'' to stop it]].
* [[http://scp-wiki.wikidot.com/scp-106 SCP-106]] "The Old Man". An entity resembling a rotting old man. It causes severe corrosion and decay of whatever it touches. It drags its victims into its pocket dimension (which it seems to have complete metaphysical control over) and slowly tortures them for hours or days, before ejecting their mutilated bodies back into this world. Take a look at the page [[http://scp-wiki.wikidot.com/scp-106 pictures]]. As if that wasn't enough, it's completely indestructible and almost impossible to successfully contain.
** Finally, someone agrees with me. Not even making jokes about it and [[http://scp-wiki.wikidot.com/scp-033 SCP-033]] helps with the horror.
** ''"SCP-106 appears to prefer human prey items in the 10-25-year-old age bracket."'' Aside from how horrifying ''that'' is, I don't even ''want'' to know how the Foundation discovered this.
** The procedure for its recapture is, if possible, more terrifying than it is. Namely, taking a human in said age bracket and injuring them by breaking a bone or cutting a tendon, placing them in a cell, and broadcasting their cries to lure in SCP-106. If SCP-106 isn't taking the bait, ''additional damage'' is inflicted. If it still isn't working, more "prey" objects are brought in. ''Hoe-shit.''
* [=SCPs=] [[http://scp-wiki.wikidot.com/scp-076 076-2]] and [[http://scp-wiki.wikidot.com/scp-682 682]]. Both are indestructible, very sharp killing machines. Sure, you can put them down for now, but they'll just come right back again in a few minutes.
** SCP-076 has a long description on its page about how in "the worst breach to date", its containment site was forced to set off a nuke, killing everyone and incinerating the location... '''[[NighInvulnerable and failing to kill the SCP]]'''.
** SCP 682 is described as a reptilian monster able to mutate and regenerate body parts, with hyperintelligence, and [[OmnicidalManiac a hate of all forms of life]], and the ability to adapt to anything. It's still capable of talking (usually in the form of obscenities and threats) with as much as 80% of its body mass destroyed, and needs to be kept in an acid bath so as to constantly keep it weakened. What makes it worse is the fact that they have to experiment with other [=SCPs=] to try and find away to permanently destroy it. The most frightening thing? It usually fails, and then it becomes immune to whatever they tried.
** How about the interaction between 682 and 826? [[http://scp-wiki.wikidot.com/scp-826 862]] is a pair of pewter dragon statues that transform the room it's in into the setting of any book placed between them. If the people fail to escape the room, they will lose all memories of their past lives, and the story will rewrite itself to incorporate them. Realizing this, the SCP wrote a 12 page short story called "The Generally Nice, Friendly Thing That Can And Will Kill SCP-682 Permanently if it So Much As Spots That Damn Lizard", that was just a description of a plain green field, and a large monster whose sole descriptive quality was the stated ability of permanently killing 682. So, they put 682 in there, and in a matter of minutes, the plain green field turned into a scorched crater-filled wasteland, and the 12 page short story had become a [[strike:1,000+]] 209 page epic called "The Generally Nice, Friendly Thing That Tried To Kill SCP-682 Permanently But Failed" describing the epic battles between this monster and an innocent creature whose very existence was based around its ability to destroy 682. And 682 won. [[TearJerker Poor thing]].
** Yes, that's right. They wrote a story about something that ''specifically could kill 682'', and 682 ''killed it''. That's how unkillable the bloody thing is.
*** What makes it worse is [[http://scp-wiki.wikidot.com/scp-343 SCP-343]] will not get near 682 and calls it an abomination.
*** [[WordOfGod Dr Gears]], 682 creator, says that, in his view, 682 wants to kill everything because, through his eyes, life on this reality is so utterly ''wrong, disgusting and frightening'' to him that his only response is to destroy everything. It makes you wonder just how his homeplace looks like...
*** Sounds to me like a ''VisualNovel/SayaNoUta'' crossover waiting to happen. The human staff would like her fake form, 682 would like her real one, and until she destroys the planet everyone wins!
*** And SCP-053 ''likes'' the thing! It even seemed to like her back, actively trying ''not'' to scare her when they first made contact and even letting her draw on it with her crayons. Although SCP-053 looks and acts like a three year old girl, everyone over the age of three has an irresistible desire to kill her after ten minutes of exposure, and everyone who tries dies painfully. Perhaps SCP-682 feels the same way about humans as humans do about SCP-053. In which case, one wonders where 053 ''really'' came from...
* [[http://scp-wiki.wikidot.com/scp-689 SCP-689]], which will not only kill you if you break eye contact with it, it will teleport to you, and anybody who sees it now will also be in danger of death.
* 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 SchmuckBait, with the full knowledge that they'll ignore their orders and do something stupid... just so that the scientists will see what happens.
* [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] is a clockwork... thing that grows by absorbing all nearby metal objects and can brainwash anyone nearby into "feeding" it. [[http://scp-wiki.wikidot.com/scp-271 SCP-271]] is an engraved coin, whose inscription spreads to nearby objects and turns them into an indestructible metal with unknown properties. Accidental tests on living organisms suggest that both being absorbed by the machine and being converted by the coin are excruciatingly painful. There is an obvious reason these things are not to be allowed in the same room. The Church of the Broken God wants to try it out.
* [[http://scp-wiki.wikidot.com/scp-002 SCP-002]] is a ball of flesh with a door in it. Through the door is a modest apartment, complete with furniture made out of the body parts of the people it's killed.
* The old [[http://scp-wiki.wikidot.com/scp-112-arc SCP-112]] is an ArtifactOfDoom activated in the presence of any non-virgin or non-castrated person. And it has been stolen by radical Muslim terrorists. Get the idea?
* [[http://scp-wiki.wikidot.com/scp-415 SCP-415]], The Harvested Man. ExactlyWhatItSaysOnTheTin.
* [[http://scp-wiki.wikidot.com/scp-231 SCP-231-07]], a girl of undefined age who was impregnated with some kind of CosmicHorror by a Satanic sex cult. The only way to keep it from being born is by putting her through "Procedure 110-Montauk" every twenty-four hours, which is described as involving "brutally (DATA EXPUNGED)". Since it can only be carried out by convicted sex offenders among Class D Personnel, and is being supervised by employees who have passed a psychological examination in which "mild sociopathic tendencies and marked sexual deviancy are not to be considered automatic fail conditions" (an early warning and implication of who carries this out) it's [[strike:pretty obvious what it is]] [[WordOfGod 10 times worse than whatever you think it is.]]
** Here's one bit of extreme Nightmare Fuel relating to SCP-231: Some of the staff who were involved in the project have taken amnesiacs to forget it, and false memories have been implanted. Which means that ''you'' could have been on the project and not even remember it.
** Oh, and they started using amnesia-inducing drugs on 231 herself; the sum total of 110-Montauk was starting to induce a form of shell shock in the victim. As a constant level of agony and terror needs to be inflicted to supress the EldritchAbomination, they started wiping her mind of her knowledge of Montauk. Eventually it was determined that a weekly dosing cycle was most efficient, as the 3rd to 4th time is the most mentally devastating; the first time is horrible, the second time establishes a pattern, and the third confirms that [[DespairEventHorizon this is what the rest of your life is going to be like.]]
** The article contains an addendum added by one of the heads of the SCP foundation specifically stating (presumably to set straight employees having second thoughts about all this) that while "Procedure 110-Montauk" is quite possibly the most horrifyingly evil thing the SCP foundation has ever been involved in, failure to carry it out will result in the EndOfTheWorldAsWeKnowIt, judging by the death tolls that ensued when SCP-231-01 through SCP-231-06 gave birth. Sweet dreams.
** The specific age of SCP-231 is not specified, only a minimum and maximum, both of which are censored in the article. But the minimum is a single-digit number.
** And to make matters worse, it was originally just a censored two-digit number, but after a troper breathed a sigh of relief that at least 231-7 was not a child, the Foundation saw it and changed it, [[TemptingFate and replied to that post with "this is your fault,]] [[NiceJobBreakingItHero you made this happen".]]
** In such fine print that you may have to View Source to find it: [[spoiler:"Don't believe it when they say they're trying to save her. Why would they bother? They've got exactly what they want exactly where they want it."]]
** They're going to have to come up with ''something,'' though, because even barring any changes in her situation eventually she's going to die of natural causes, and the death of the previous six 231 hosts released their whatever-it-is. Since it wouldn't really make her situation much worse than it already is, putting her in something like the other SCP which is an iron maiden which prevents the victim aging or dying could delay the problem, but she'd still age while she was outside it for the Procedure, so it still wouldn't work indefinitely. Not to mention her [Data Expunged] may interpret that as an attempt to kill her and figure it was time to do its thing. And being fed via IV doesn't exactly prolong life, so they probably have less time than the average lifespan. Also, think about this; does she know what the thing she's carrying is, and would it make her situation worse or better if she did? If she did find out, either she may think "oh well, it'll prevent something even worse happening" and her distress level will be lowered slightly, which, since the distress level appears to be the important part of the Procedure, will be a problem, or she'll want to release the thing for revenge purposes. Pity the portal into a world already undergoing zombie apocalypse is no longer open, as they could have just shoved her through there - that world is already ending, and she'd no longer be the Foundation's problem. 231's situation, to me, is just plain {{Squick}}. The Nightmare Fuel aspect comes into play with the fact that they're keeping this thing under control using either the minimum safe or the only way to do so, ''they don't have a backup plan, and since the previous six hosts are all dead they don't have a way to safely test any plans they do come up with.''
** I have a WMG over on the WMG page to explain why they don't have a backup plan and why she "stays perpetually young".
** Alternately, imagine being part of the support staff for the 231 containment site. Knowing what you're ordering done to the girl, watching it every day, obtaining supplies and materials to enable it, terminating anyone who tries to stop it. There's a reason why so many people associated with this thing commit suicide.
* One of the most disturbing things about the SCP series (for some) 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.
* Even the [[http://scp-wiki.wikidot.com/scp-series#toc12 joke SCPs]] are creepy. Take [[http://scp-wiki.wikidot.com/scp-000-j SCP-000-j]], for example. It's a catalogue of every SCP item, which anybody can apparently order through a simple phone call as if they were everyday items. When one of the testers did call and order one of them (a safe-level item), it disappeared from its storage and mysteriously got delivered to his office, and the amount he would have paid for it vanished from his next paycheck. Now imagine somebody finding this catalogue and ordering one of the Keter-class items...
** Imagine them ordering 682?
* 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.
* The [[http://scp-wiki.wikidot.com/decomm:scp-316-d termination log of SCP-316-D]] is absolutely horrific. Even though he seems to be one of those Gary Stus that pretty much psychically forces you to like him, Surveillance Log x316███ was just gruesome. Also: The thought that he could wake up on a space probe en route to the sun is what most everybody's worst nightmare is made of.
** Given the nauseating levels of Gary Stu-ism given to SCP-316-D, I would argue its death was not nearly nightmarish enough. That said, the only reason the entry remains open is to demonstrate precisely the sort of puerile drivel that should never be added to the site in the first place.
* SCP-001 is generally reserved for the largest and most brickshittingly terrifying SCP concepts, so much so that the users of the site would rather not ruin the mystery by having a single canon SCP-001.
** The [[http://scp-wiki.wikidot.com/scp-001 SCP-001 proposal page itself]]. When you scroll down to see why "SCROLLING DOWN WITHOUT PROPER INNOCULATION WILL RESULT IN IMMEDIATE CARDIAC ARREST FOLLOWED BY DEATH," you will shit bricks. What makes it worse is that the image is designed to kill you. Now if that were an SCP, and it could spread...
** It's not supposed to be scary. The idea is that the patterns in the image are so illogical and confusing that, if viewed without safety measures, will cause the brain to 'crash', so to speak. This is not the first time such a concept has been explored.
** If you're curious that's a randomly generated image from the [[http://electricsheep.org/ electric sheep screensaver]]
** One of the possible SCP-001s. Completely harmless by itself. Its just [[http://scp-wiki.wikidot.com/jonathan-ball-s-proposal a sheaf of stapled papers containing detailed reports of the SCP items]]... except that every time you look at the report, the report is on a new SCP item, which then appears somewhere in the world. Let the sheer terror of that concept work its way into your brain.
** One of the other possible SCP-001s is [[http://scp-wiki.wikidot.com/dr-clef-s-proposal a huge humanoid figure standing in front of what is more or less the gate of Eden]]. Getting within 1 kilometer of it will get you not only killed, but wiped from existence. If it ever goes active, TheEndOfTheWorldAsWeKnowIt will ensue. Making matters worse is that the page includes a transmission from TwentyMinutesIntoTheFuture about SCP-001 waking up and bringing about said apocalypse. Mega-gulp.
** שמע ישראל יהוה אלהינו יהוה אחד [[spoiler: In case you were wondering, that's the most important prayer in Judaism. It's supposed to be your last words.]] Translated: [[http://en.wikipedia.org/wiki/Shema_Yisrael "Hear, O Israel: YHWH is our God, YHWH alone."]]
** My favourite concept for SCP-001: [[spoiler: [[Wiki/SCPFoundation a massive worldwise organisation that acts like a sociopathic MIB agency]].]]
** Another recent possible SCP-001: a large onyx gemstone with an infinitely fine fractal gold filigree, apparently serving as a lock for an unknown object. Doesn't really seem scary, right? [[spoiler:It turns out that the minute variations in the cosmic background radiation has ''the exact same pattern'' as this onyx lock. It's implied that our universe is contained in a similar object, and possibly the artifact in question. The Foundation is currently trying to [[ApocalypseHow open and/or destroy it.]]]]
** Bright's proposal for 001: [[http://www.scp-wiki.net/scp-001-o5 The Factory.]] Just...read it.
** [[http://scp-wiki.wikidot.com/dr-manns-proposal Dr. Mann's proposal]]. The SCP itself is very simple, just a circular gravel path. Travel clockwise, and you move normally. Travel counter-clockwise, however, and the path appears to go continuously uphill. [[MindScrew Even if you go all the way around to the start.]] The real horror comes when one reads the attached document from one of the founding Overseers. [[spoiler: Analyzing the Gravel Path led to the initial founders of the Foundation to the initial understanding of bending reality that allowed them to start manufacturing SCP objects. And the Foundation never "found" ''any'' SCP. They ''made'' them. ''All of them.'' -231, -051, -616, -682, all of them ''were created by the Foundation.'']] And the scariest part? [[spoiler: SCP objects are no longer being manufactured. They're just ''appearing'' in containment, with no indication of where they came from, and the Foundation has reached the point of no return.]]
** [[http://scp-wiki.wikidot.com/sandrewswann-s-proposal S Andrew Swan's proposal]] is a masterpiece of MetaFiction ParanoiaFuel. The details are so confidential that even the ''description'' has been expunged and the directives state there is no way of containing it without risking a ''ZX Reality Failure event'' (the destruction of the observable universe). No-one except the O5s is allowed to know anything about it at ALL. But there is a hidden message on the page from a researcher who worked on it and managed to escape the purge detailing it: [[spoiler:The reason the SCP Foundation discourages attempt at cross-referencing [=SCPs=] and looking for patterns in their seemingly random nature is that once, ''they did'' try to develop a Grand Unified Theory of [=SCPs=] and they discovered that reality is constantly shifting, things appearing and disappearing as if they'd never been, even whole sections of the Foundation's history changing. Eventually one of the researchers discovered the pattern- the shifting development of reality "toward narrative coherence, toward a plot..." And they discoverered the truth.]]
--->[[spoiler:But we found out there is a God, and it is SCP-001.]]
--->[[spoiler:[[NoticingTheFourthWall And it's a bunch of horror writers.]]]]
** Oh, and there's more: if you enter the encryption key identifying you as an O5 member with full authorisation of the O5 council, you can read Containment Protocol ZK-001-Alpha, their final sanction against SCP-001 to be used only in the most dire of emergencies. [[spoiler:They will virally insert a series of memetic attack agents into the SCP database itself that will [[TheFourthWallWillNotProtectYou infect members of SCP-001 and induce a state of calmness and well-being, followed by catatonia and finally a quiet death]]. [[ParanoiaFuel That's right, they've prepared a weapon to kill YOU as you browse the database]].]]
* The last line in Baba Yaga's entry was far, far more disturbing to [[{{Tropers/Whitewings}} me]] than poor 231-7's treatment. At least the higher-ups know that what they're doing to her is horrible, and want to find a way to help her. Quote: "While SCP-352 prefers any type of human flesh over any other type of meat, it appears to have a special propensity for children between 0 and 2 years of age. After observation of highly elevated levels of co-operation and a reduced tendency to attack staff while consuming flesh of this type, a possible alteration in the current diet is being considered."
** [[spoiler: No, they ''don't'' want to save 231; in very fine print after the end of Addendum 231-B, you can read: "Don't believe it when they say they're trying to save her. Why would they bother? They've got exactly what they want exactly where they want it."]]
** What, [[http://scp-wiki.wikidot.com/scp-352 this]] Baba Yaga? The Foundation just wants to make her more manageable by [[MoralEventHorizon feeding her toddlers]]. This is less horrifying when you realize that there's an SCP that turns animal flesh into human flesh, and, by logic, baby animal flesh into baby human flesh, but still. Don't tell anybody, they'll probably make an addendum rejecting it.
* [[http://scp-wiki.wikidot.com/scp-507 The guy who randomly teleports to alternate dimensions]], including one that apparently had the Joker who was right in front of him when he turned the flashlight on. "Back so soon?" The poor lad's reaction was probably the same as yours would be. Not to mention "...the spiders...".
** The interview log when another version of that teleporter shows up from an alternate dimension is terrifying. Basically they refuse to elaborate on which one is from the "real" dimension, to keep the other guy safe. At the end, one reveals that "In his reality, Lincoln was killed while sleeping by his then vice-president, instead of by General Lee." The interviewer responds "In our world, Booth assassinated Lincoln." The end of the article just states that "Subsequent testing revealed that SCP-507s abilities have no biological basing, and that severed pieces will still “shift” along with the main body."
** During one of his trips to another reality, 507 arrived in what seemed to be the facility, only in a state of disuse with corpses covered in a strange, breathing mold. Further exploration revealed that possibly ''the entire world'' was covered in the stuff. Upon further inspection of a mold sample 507 brought back, it was found to be very similar to both [[http://en.wikipedia.org/wiki/Cordyceps Cordyceps Fungi]] (some varieties of which basically brain-wash their hosts) and a fungus produced by - wait for it - [[http://scp-wiki.wikidot.com/scp-407 SCP 407]]. The Foundation consequently restricted experimentation with 407, and all known copies were terminated by "Serpent's Hand," but no one is certain if more copies may be found elsewhere.
* [[http://scp-wiki.wikidot.com/scp-294 SCP-294]] is a coffee machine that can dispense just about any kind of liquid. If you value your appetite, do not use "joe" as a synonym for "coffee" when inputting what drink you want, especially if your name is Joe.
** Said machine can dispense "My Favourite Drink", which is tailored to the individual's tastebuds, and "The Best Drink Ever", which causes the drinker to become depressive and commit suicide because "everything else is just a letdown now." For more straightforward ways of killing you, it will happily dispense any kind of acid. There's a ''reason'' why they have two security guards stationed there with orders to shoot anyone who is trying to order anything other than normal drinks for research.
** On the other hand, it also turned out "[[CrowningMomentOfHeartwarming Something Cassie will like]]," a [[HitchhikersGuideToTheGalaxy Pan-Galactic]] GargleBlaster, and a "cup of relevant medical knowledge."
** When asked for something that could kill SCP-682, the liquid was so intense it vaporized the entire site SCP-294 was in, apart from a small patch surrounding the machine. Given cases with other SCPs like this, whether it would've worked is anyone's guess.
* Speaking of disturbing food dispensers, [[http://scp-wiki.wikidot.com/scp-261 SCP-261]] is a vending machine that dispenses snack foods that might be normal, strange or bizarre. As [=SCPs=] go, it's actually pretty fun and not too scary. The disturbing part comes as you slowly read more and more stories about what comes out of the vending machine. The first time living food is dispensed, most researchers refuse to eat it and are as distressed by the idea as most people would be. But as more and more living food items are dispensed from the vending machine, researchers get more and more casual about it, until reports of the living, potentially thinking beings only describe their flavor. As if cramming the recently dead bodies of various cute little alien critters popping out of the machine is the normal and obvious thing to do.
** Another fun result from SCP-261 is "TASTE ME", an obvious reference to Alice's Adventures in Wonderland. It's funny, right until the part when the test subject eats it, goes into convulsions, and dies due to brain expansion. "Analysis of the cake showed large amounts of human growth hormone as well as several unidentified chemicals." Gee, thanks for ruining that book for me.
** Something really horrifying are the products dispensed labeled FOOD and DRINK. People who ate the FOOD became emotionless and dull-witted, while people who drank the DRINK became more and more subservient. Doesn't sound so bad by itself, [[FridgeHorror but think about]] where they might have came from, and what those products are used for there...
** And then there's the can of "Prangles." Once you pop, you can't stop. '''''Ever'''''.
** [[NightmareRetardant It also produced]] [[http://tentaclegrape.com/ Tentacle Grape]].
* [[http://scp-wiki.wikidot.com/scp-835 SCP-835]] was a collaboration between two authors: one of them was the guy who wrote the infamous SCP-231. The other wrote SCP-682. Their goal was to create the ultimate in squicky [=SCPs=]. Some would say they succeeded. For the full impact, read the article first, then the "uncensored" version, then the "uncensored" version of the exploration log.
** SCP-835 also serves as a bit of {{Fridge Brilliance}} [[HighOctaneNightmareFuel Nightmare Fuel]] for the entire SCP series. Now you know what kind of disgusting, freaky things are behind all those (DATA EXPUNGED) boxes, and they're exactly as bad as you'd think. "Now we can be together, just like he wants..."
** That adds sort of a ghoulish edge to several joke [=SCPs=] where [DATA EXPUNGED] was used for laughs.
** And then someone went and added a picture for 835. [[BrainBleach Cripes.]]
* The former [[http://scp-wiki.wikidot.com/scp-995 SCP-995]], an object that is too mentally scarring for many to describe. At best, it's been described as an "Infinite Devil Machine." It's required to be kept in a blessed lead container full of also-blessed holy water, which turns black and darkens whatever room its in. Recorded images of it breaking out of its container show tendrils poking out of its container. Unfortunately it's been deleted due to negative ratings and changed to a device which drives people insane as it touches an electric conductor. Eventually it was deleted altogether, although the original article can still be found [[http://replay.waybackmachine.org/20090317090832/http://scp-wiki.wikidot.com/scp-995 here.]]
* [[http://scp-wiki.wikidot.com/scp-217 SCP-217]] is a virus that turns people into machines. It can affect any animal, replaces organs and such with mechanical parts, and the affected creature becomes repetitive and locked in a set pattern of behaviour. Scared now? Oh and did I also mention that the Church of the Broken God wants to bring it into contact with [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] and [[http://scp-wiki.wikidot.com/scp-271 SCP-271]]?
* The worst one was [[http://scp-wiki.wikidot.com/scp-055 SCP-055]]. Which was also the coolest. Imagine seeing something, and not being able to describe it. It basically makes you forget anything related to it, being reduced to what it DOESN'T look like. [[http://scp-wiki.wikidot.com/incident-report-i-028-f This doesn't help either]]. An area that makes people gain immediate knowledge of a random subject. A man enters the area, goes into a fit, and afterwards forgets he was even in the area. Locked the memory out of sheer horror? Amnesia?
* Someone [[http://scp-wiki.wikidot.com/a-man-at-the-top-of-his-profession 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!
** It's no longer canon.
** [[OrwellianRetcon Of course it's no longer canon.]]
* [[http://scp-wiki.wikidot.com/scp-590 SCP-590]] is (objectively) nothing compared to most of these, but the fact that they purposely destroyed his mind, reducing him to the functional level of a three-year-old -- and for no reason other than to make him more controllable -- chills me to the bone. Worse than that is reading the experimental logs of SCP-978, a camera that shows the photographed subject doing what it desires to be doing rather than what it actually is doing. 590's picture is absolutely heartbreaking and one of the most chilling things she's read on the whole site.
* [[http://scp-wiki.wikidot.com/scp-093 SCP-093]] is my favorite. Read the whole thing, including the test reports, in order, and then read the last link on the page. It sent shivers down my spine; the reports themselves are creepy and unsettling, but the final report is just chilling.
--> [[spoiler:there was no war it was him him him him him IT. IT! it came from between the folds of time and space and worlds and light and dark something that is but should not be slipped in and called out to them as their god and they believed it and they tasted it and touched it and layed with it and became its property and did its will and IT IS STILL HERE]]
* 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.
* [[http://scp-wiki.wikidot.com/scp-899 SCP-899]]. "A psychic and telekinetic phenomenon that most commonly manifests as groups of hostile phantom children." Then they went and exposed it to [[http://scp-wiki.wikidot.com/scp-573 SCP-573]]. To give some hint of how "successful" that experiment was, [[http://scp-wiki.wikidot.com/diary-573 this]] is what happens when a perfectly ordinary person uses 573, and taking a picture of it with SCP-978 resulted in a [DATA EXPUNGED] and a note that "It appears SCP-573 is indeed sentient in any case."
** GOOD GOD THE PICTURES. Seriously, they're [[UndeadChild freaking scary.]]
* [[http://scp-wiki.wikidot.com/scp-604 SCP-604]]. What makes it particularly bad is that it has no apparent effect on the users, meaning they chose to use it ''as they did of their own accord''. There are extensive records of what the thing can do, because its former owners charted their progress. And when they succeed...
---> (a waiter comes in pushing a cart with a wooden box on top. The box has several slots and holes opened in it, and tubes trail out, connecting to IV bags and tiny batteries. A mewling comes from within)
---> (The box is lifted up over a plate, put on it, and then pulled off. There is a flash of some kind of twisted, shaved animal, but then a human head appears.)
---> (the human head is that of a man around thirty five, with thick black hair and sideburns. He has extremely pale skin and dark circles under his eyes. He is severed at the neck, which reveals muscle and a bloody hole.)
---> Head: Where am I? Who am I?! What the hell is going- (Begins looking around and turning up, down, and to the sides) Everything seems at a weird angl- hey, what are you doing! Get that knife away from me!
---> Waiter: Bon appétit, gentlemen.
---> Head: (begins screaming)
* [[http://scp-wiki.wikidot.com/scp-847 SCP-847]]. {{Uncanny Valley}} aside, the "[DATA EXPUNGED]", the attacking of all females in the area, and the victim being killed by 'massive blunt trauma' all lead to some unsettling implications.
* There is something distinctly disturbing about [[http://scp-wiki.wikidot.com/scp-914 SCP-914]]. Testing shows that in spite of its supposed lack of sentience, it seems to have a rather twisted sense of humor, and on multiple occasions the "very fine" setting, which refines something to its most perfect form, has produced a (mercifully inanimate) replica of SCP-682, suggesting that it may have a "thing" for the beast. The fact that it knows 682's "home phone number" doesn't help matters.
** Testing of [[http://scp-wiki.wikidot.com/scp-978 SCP-978]] on SCP-914 indicates that what 914 really "wants" is to have a sixth setting on its control knob, that goes ''beyond'' Very Fine...
** Every time someone tries to run something organic through the "Very Fine" setting, it gets all "[DATA EXPUNGED]". But some of those have rather... telling... notes relating to "cleanup," and they've banned any further attempts to use it on living things.
* [[http://scp-wiki.wikidot.com/scp-342 SCP-342]]. It takes the form of a ticket to some kind of public transit, and once you get on you can never get off. Just... read it.
** "And her never returned, no he never returned, and his fate is still unlearned. He shall ride forever 'neath the streets of Boston. He's the Man Who Never Returned."
* [[http://scp-wiki.wikidot.com/scp-400 SCP-400]] is a phone booth that can contact anyone. [[http://scp-wiki.wikidot.com/scp-519 SCP-519]] is a phone containing a voice that is on permanent Sarcasm Mode. When they tried to ring 400 through 519, 519's response was, and I quote, "Ooooh, boy...". On the other side, 400 rang, and a guard picked it up, only to be pulled apart by an unseen force. Then there was a containment breach resulting in the entire site around being locked down and everyone terminated.
* [[http://scp-wiki.wikidot.com/scp-826 SCP-826]] is a very ordinary looking set of pewter dragon-head bookends, but if you close the door of the room, put a book or DVD between them, and open the door, the doorway will be a portal to the world of the book or film. It seems almost to be a joke entry, with a note about a researcher who was demoted for (apparently) planning to do very naughty things to a female Disney character on a DVD. But what if you tried it with the Necronomicon? And this thing is listed as "safe." Not Euclid, not Keter. "safe." Brr.
** Safe only means that the SCP can be reliably controlled, as long as you have appropriate protocols, and aren't inherently hostile to humanity. This is an easy mistake to make, made worse because the standard definition of safe does apply to some of them. And then others kill you in horrible ways, but are easy to keep under control. Good luck guessing which is which.
** And if you don't find the bookends within the story in time, you can ''never escape''. You get {{Mind Rape}}d into a background character...''forever''. And you can't even choose which part of the story you arrive in. So if you arrive at the very end...tough luck.
** Dear God, imagine what would happen if someone put a DVD copy of MarbleHornets in between SCP-826? ... shit.
** Do remember that even if you put in something so horrible that no one could possibly survive it, its effects will still be confined entirely to one room. All you have to do is warn people not to go in.
* [[http://scp-wiki.wikidot.com/scp-701 SCP-701]]. Especially Incident Report SCP-701-19██ and that photo.
** Granted, that's an unnerving photo. But there's something amusing about how the report is basically a cross between a tenth-grader's meticulous school report on The Scottish Play with a ''literal'' KillEmAll ending.
** The URL for the Incident Report betrays what date 19██ is: [[spoiler:1997]]. Also, the state mentioned as the place where the video tape was recovered is [[spoiler: Ohio]]. It seems those ██s aren't impenetrable after all.
* [[http://scp-wiki.wikidot.com/scp-740 SCP-740]] will make your skin crawl. An infection that eats you alive, and then makes spiders burst out of your skin (Hopefully you'll be dead by then, if not you have about 20 minutes to live). Then they EXPLODE to create more infected with the spores they release.
* [[http://scp-wiki.wikidot.com/scp-610 SCP-610]]: It's like the [[DeadSpace necromorphs]] and The Flood rolled into a single package. Squick warning, obviously; the page image is [[BodyHorror especially bad]] (or [[NightmareFetishist awesome]]).
** Even worse is it`s official nickname: ''The Flesh that hates''.
* [[http://scp-wiki.wikidot.com/scp-439 SCP-439]]: It's a parasitic insect resembling an earwig that will ''[[BodyHorror turn your body into its hive.]]'' It enters your body ''[[ParanoiaFuel while you're asleep,]]'' and then, in a process shown to be ''very'' painful, causes your body to deform into a spherical mass while the insects ''eat you alive from the inside out.''
** And then there's the addendum at the end, which shows an SCP researcher operating on the "bone hive", and finding that the eyes had not yet been eaten. She shined a flashlight on them, and ''the eyes followed the beam.'' Think about the [[AndIMustScream implications.]]
* 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.''
** On the other hand, considering the world evidently still exists, whatever he's doing has worked so far.
* [[http://scp-wiki.wikidot.com/scp-804 SCP-804]]: A piece of "art" that, when activated, slowly but surely kills all humans and destroys all man-made works in an ever increasing radius around it. The only saving grace is that said artwork is not immune to its own effects. However, the most nightmarish element of this SCP isn't its potential to destroy the world. No, the scariest part is that, according to the former lead researcher, Dr. Sorts, [[NotBrainwashed the SCP has no memetic influence on people]]. The people who created and activated a device that would wipe out humanity did it because, in Dr. Sorts' own words, ''they wanted to do it''. That the SCP Foundation transferred Dr. Sorts to another project and is continuing testing for a memetic component means either 1) the Foundation wants to be absolutely sure that no mind control is involved or 2) ''even the Foundation'' doesn't want to believe that there ''really'' are people in the world evil enough to murder humanity entirely of their own free will.
** The people "evil enough to murder humanity entirely" were well-intentioned extremists, at least the original ones who sacrificed themselves. As in, they wanted to get rid of humanity because they thought it had a greater net negative than positive effect on other lifeforms. Meanwhile, the Foundation has terminated or is trying to terminate several lifeforms for the same reason (and real life humans do this all the time with diseases, though with other life the extinction we cause tends to be accidental). So when you think about it, the creators of the SCP-804 merely had the same views on their fellow humans as most humans do on lifeforms that threaten them. You could argue that the SCP-804 creators are more evil because they have betrayed their own species, if you like... or you can argue that their motivations are actually more objective, since their views on what lifeforms are more harmful aren't determined by what benefits their personal continued existence. Either way, thinking about this for long periods of time is a bit like reading SCP-079 (an increasingly rational and objective computer that nonetheless clearly hates humans, if not all life), in that it has a creepy "but what if the SCP is RIGHT?" air to it.
* [[http://scp-wiki.wikidot.com/scp-354 SCP-354: The Blood Pond]]. It's a pond in the Canadian wilderness that is full of a liquid similar to blood. Highly dangerous creatures emerge from it from time to time; most of whom have nothing in common. And according to one SCP agent, it's alive. And intelligent. And angry. ''[[spoiler: And growing]]''.
** The fact that a seemingly normal human emerged from the pond at one point for ostensibly diplomatic reasons and was shot on sight probably didn't help on the "angry" front.
* Nearly every Keter-class SCP could be considered HighOctaneNightmareFuel. Given that the criteria for Keter classification are: 1) it's too valuable, dangerous, or invulnerable to be neutralized at present, 2) it's an extremely significant threat to humanity, civilization, and/or ''reality'', and 3) ridiculously extensive and precisely followed containment protocols are required to keep the SCP isolated and secure (and even then it may only be a matter of time before it gets out of control)...
* [[http://scp-wiki.wikidot.com/scp-120 SCP-120]] is a pink kid's swimming pool that works as a PortalPool, cycling between 11 locations each time you send someone through. The 11 locations include the 5 Lagrange points. Which are in space.
** It's a convenient way of teleporting, though, except for the Lagrange points. So they simply... cause it to cycle through them. Using D-class personnel.
** Also, it was discovered because of "reports of missing children". [[KillItWithIce Think about]] [[KillItWithWater what happened]] [[ShiftingSandLand to those]] [[ThrownOutTheAirlock children]].
* [[http://scp-wiki.wikidot.com/scp-662 SCP-662]] is a silver bell that summons a friendly, polite butler named Mr. Deeds, who will gladly perform required services by asked by the ringer, within reasonable limits. He'll fetch you a sandwich, but not one made of human flesh, and he'll bring you a grenade, but not a nuclear bomb. Seems fairly harmless, right? [[spoiler: Then they asked him to assassinate a D-class personnel, which he did with [[AlmightyJanitor disturbing precision with a buck knife]].]] Suddenly, Mr. Deeds doesn't seem like the nice, friendly fellow we all think he is....
** He might very well be harmless, but read the end of the [[http://scp-wiki.wikidot.com/662-l1 interview log]], and the interrogation by Agent Graves. [[spoiler: So, they kill him thoroughly, perform an autopsy on him, discovering nothing terribly interesting about him, and then they "permit" his body to vanish.]] Shortly thereafter, he is summoned, ready and willing to perform his duties. So, he's nigh omnipotent, willing to perform any service or retrieve any object, within his capabilities, and [[spoiler: he cannot be killed.]]
** I actually think this says far more about the way the Foundation deals with D-Class personnel. They are considered so inconsequential that Mr. Deeds will consider nothing much to kill them. Again, the Foundation is ''almost'' worse than the stuff they contain.
** ''Why'' can't Mr Deeds explain how he does what he does, even under torture, and why does he appear so uncomfortable when asked? The photo of him from the Desire Camera showed him exactly as he was, posing for the photo, which suggests his greatest desire is to do what he's instructed to do. Is he so uncomfortable when asked where he goes and where the items come from because he's unhappy that he's literally unable to explain, or because something worse will happen to him if he does? Also, he was disturbingly calm when offering to be fed to SCP-682.
* [[http://scp-wiki.wikidot.com/scp-668 SCP-668]], [[spoiler: the knife used to kill Kitty Genovese]], is utterly terrifying to people who don't deal well with helplessness. Read about what it takes in order to reclaim it if lost. Now think about what that would enable any garden variety sadistic creep to do. That thing's pretty much a catalyst for a wide variety of end of the world scenarios.
* [[http://scp-wiki.wikidot.com/scp-597 SCP-597]]. [[FreudWasRight The Mother loves you.]] [[MindRape You will love The Mother.]] [[FateWorseThanDeath The Mother will provide for you forever.]] Why this powerfully telepathic...''thing''... has not been terminated or even properly contained is a mystery.
** Probably because it's ''FetishFuel'' for some of the Foundation's higher-ups.
** Let's count everything that's wrong with SCP-597 or "The Mother", shall we? Well, for starters there's what it is, a massive ball of mammaries, nipples for every species of mammal, and no matter what the milk will always be perfect for whatever mammal's drinking it. Most mammals can't resist it. Bats, rodents, cats, dogs, all of these can be found sucking on the thing, and refuse to let go; it's described as being a sexual, psychological, and hunger compulsion all at once. Also, the male staff have sex with it. Regularly. So regularly in fact that they don't do anything to discourage it. The thing is always covered with slobber and semen, which D-class personnel clean. Of course, that just means they get brainwashed faster than everyone else. They also have the task of collecting the milk for study (which they often sneak whole bottles off for themselves). All staff at its facility are affected. In early stages, people who quit smoking for years have a 100% relapse rate, people binge on snacks (especially dairy products) or chew gum. So much gum that they choke on it. Later stages the behavior gets even more extreme. Formerly heterosexual woman begin to engage in lesbian sex, some men become rapists, others latch onto large breasted women as surrogate mothers. If things are allowed to progress this far, all milk samples from The Mother will be fought over by the staff. Next staff begin to regard the mother with superstitious awe, worshiping it with incense, food offerings (even though it doesn't eat) and animal sacrifice. One scientist circled every one of the nipples with a red marker and wrote the word "life" next to them before killing herself. Then they begin to revert into child like states, losing bladder and bowel control, masturbating constantly, calling it "mommy", crawling on all fours and talking like toddlers, before finally curling up and joining the rodents and bats in suckling. The milk will keep them alive the rest of their adult lives, and they will be in blissful happiness, but their muscles will atrophy, and their teeth will fall out, and they will experience digestive problems from the sudden switch to a liquid diet. There is no way of stopping this. Even if you send them away from it, the effects are permanent, and they have several data expunged section describing staff that took this mental illness home with them (including one where it was implied that a man raped and killed his own mother for "not being good enough"). The only thing they can do is constantly rotate, and kill staff members.
** Even worse: The Mother ''can'' be destroyed, but the ones who have the authority to do so use The Mother as a sexual experience, ordering a Class D to pry them off after an hour of suckling.
* [[http://scp-wiki.wikidot.com/scp-087 SCP-087]] is a never-ending platform staircase that resists attempts to illuminate it, and descending one flight of stairs lets you hear a child crying for help about 200 meters down. The people sent down one by one found something else instead...
** Plus, they sent four missions down into that staircase and you can only read the first three and they get progressively worse. But after the fourth mission it started to knock on the 'door.'
** Also terrifying are the effing ''pictures'' on the thing's page. Especially the first one. It's like one of those "when you see it, you'll shit bricks" demotivators.
** And that's not all. If you try to upload the first image to a imagehoster (you know, to avoid hotlinking), the face in the uploaded picture is ''gone''.
** There is now a [[http://dl.dropbox.com/u/10887020/SCP/SCP.zip game]] of SCP-087. Enjoy.
* 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.'' [[http://scp-wiki.wikidot.com/scp-042 SCP-042]] in particular seems to be written specifically to highlight the cruelty of the Foundation, [[spoiler: 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 ForScience. Yeah. It makes me sick too.
** 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.
* [[http://scp-wiki.wikidot.com/scp-596 SCP-596]]. That it can heal any injury would have been a great help for the Foundation, if it weren't for the fact that any physical contact with it will leave the victim permanently stuck to it and unable to move it themselves unless another person makes physical contact with the statue, killing the original subject. What's even more nightmare-inducing is that absolutely no other method can separate the two: whenever a victim is surgically removed from SCP-596, they will die and a new body will grow from the parts still attached to SCP-596.
** What's even worse is how the Foundation takes advantage of its abilities. The victims are used as ''reusable organ donors''. Since anesthetic isn't an option thanks to the SCP's powers, the Foundation used to resort to decapitating the victim in order to temporarily incapacitate them during the harvesting. Now they just empty their skulls to keep them from screaming.
* Not as horrifying or deadly as the other [=SCPs=], but [[http://scp-wiki.wikidot.com/scp-613 SCP-613]] ability to make contaminated organisms lose all color and become black and white over the course of a few days and leaving the carriers unable to perceive or remember what colors are, brought shivers to me. Luckily any healed former carriers can develop immunities to the disease.
* [[http://scp-wiki.wikidot.com/scp-204 SCP-204.]] 204 comes in two parts: 204-1 is a colony of nano-machines that follows around 204-2, protecting him/her from harm. 204-2 is a child aged from 4 to 14, with a history of being abused, who can control 204-1. When 204-2 turns fourteen, 204-1 finds a new child to protect, and, if the former 204-2 is mentally stable, the former 204-2 is given a Class-A amnesiac and put into a foster care program. That's not the HighOctaneNightmareFuel. The real HONF comes from an addendum that explains that due to 204-1 freaking out if there isn't another suitable child to imprint on if needed, the Foundation have a group of suitable candidates. However, if they really need candidates quickly, they can enlist some more candidates who don't fit the protocol- i.e., they are of a suitable age (preferably under ten), but they don't have a history of abuse. The Foundation will then '''turn them over to 'caretakers' which will consist of D-class personnel convicted of violent crimes, child abuse, and pedophilia'''. It also says that the procedure for hiring the 'caretakers' is the same one for finding people to perform Procedure 110-Montauk on SCP-231. Jesus Christ.
** Oh, and as an aside? SCP-204 will psychically manipulate whatever it's guarding into taking dangerous actions so it is forced protect what it is guarding, and thus allowed to feed. The SCP literally forces the child into danger so it can feed.
** And on top of that? Right now it's guarding a '''complete sociopath''' who is very quick to threaten people with the hungry, amoral nanomachines!
** And as if to top the whole thing off, 204 is ''ludicrously'' powerful. The initial capture required an ''Abrams tank'' and an '''AC-130'''. Yes... to capture this thing, you need not only one of the most powerful armored vehicles in the world, but also DeathFromAbove UpToEleven.
* [[http://scp-wiki.wikidot.com/scp-787 SCP-787]] is rather mundane (average scenes of grisly horror and cannibalism with some poltergeist activity), but the real chiller is '''"TO BE SORRY"''' endlessly repeating on the flight log.
* [[http://scp-wiki.wikidot.com/the-great-short-story-contest 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 [[UpToEleven kicker]]: The theme for February? '''[[AfterTheEnd Post-]][[TheEndOfTheWorldAsWeKnowIt SCPocalypse]].'''
* [[http://scp-wiki.wikidot.com/scp-764 SCP-764]]. Because puppets were not scary enough already. These will end up killing the user. How's that for a comedy routine?
* [[http://scp-wiki.wikidot.com/scp-800 SCP-800]] is an antique scroll painting that regularly changes to reflect current political relations or tensions in East Asia. It currently depicts two soldiers in combat, mirroring the tenuous state of relations between the North and South Koreas. The Foundation once performed a test to see if adding objects into the painting had any kind of effect; an expert in East Asian art added a quiver of arrows to one of the soldiers. Three days later, North Korea did...something that ended up purged from the records and stopping all further testing on SCP-800. The arrow metaphor gave me a [[EmptyQuiver pretty good guess]] [[NukeEm what happened]]...
** It gives a date of May 25th, 20██. Now, scrolling through The Other Wiki, I found [[http://en.wikipedia.org/wiki/2009_North_Korean_nuclear_test something that happened on May 25th]].
** Presumably, adding the arrows made the nuclear test occur. That's not the worst thing; there's mention that it once took the appearance of a Khmer stone carving. The description of said carving has been expunged. Predictable, considering [[http://en.wikipedia.org/wiki/Khmer_Rouge what happened...]]
** Almost all SCP [REDACTED] or [DATA EXPUNGED] marks are indicative of HighOctaneNightmareFuel or something else really gory. Most refer to something that the Foundation did, or something that an SCP did. Not the description of the Khmer carving–this was a non-fictional event carried out by real human beings. And the SCP Foundation expunged its data. [[HumansAreBastards Yeah...]]
* [[http://scp-wiki.wikidot.com/scp-823 SCP-823]]. A theme park that killed over 200 people in horrific ways (such as somebody in a mascot costume being filled with stuffing). Anybody sent in after that dies. So they can't find out what's going on, and that can't contain it because it's ''growing''.
** [[NothingIsScarier "Unable to determine context or content of above photograph."]]
** The last paragraph in the "civilian deaths" section. Someone was completely dismembered... and, at the very end, it's mentioned that he was still alive when they found him like this.
** The commander of the Mobile Task Force team was found dead from suicide. That's not the scary part. The cause of death was from [[EyeScream "forced sexual entry through left eye"]]! Think about that for a second.
** If you're savvy enough to realise some of the images are of a theme park that was supposed to open in Chernobyl, then it becomes...slightly less terrifying.
* [[http://scp-wiki.wikidot.com/scp-741 SCP-741]] is a sunken Russian submarine split into three pieces and guarded by the Foundation. The HighOctaneNightmareFuel? An attached interview with an American spy that said that the sub was carrying some kind of new weapon that not only made a bioweapons researcher sick, but that the Soviet couldn't safely control -- they sent the sub away to get rid of whatever it was.
* [[http://scp-wiki.wikidot.com/opportunity-knocks Opportunity Knocks]]. Apparently based on a recurring nightmare of the author's...
* During the experiments with SCP-914, they put in ''IWannaBeTheGuy''. Setting on Rough made up the games used for IWBTG, simple enough. 1:1 made Kaizo Mario World. Fine gave them ''Super'' I Wanna Be The Guy, which is undoubtedly near-impossible. Finally, Super Fine had all information denied by the O5's. This means that this... '''thing''' that resulted from putting IWBTG in SCP-914 has been formally denied existence of by the ''Foundation's directors''!
* [[http://scp-wiki.wikidot.com/wednesday-1 This story]], especially the ending. Watch me fly!
** [[NothingIsScarier The fact that you didn't list which SCP caused it is really freaking me out.]]
** With all of the parts written, the final ending seems to be something more akin to a CrowningMomentofHeartwarming.
* [[http://scp-wiki.wikidot.com/scp-734 SCP-734]]. Awww, it's a cute baby boy. And if you touch him your body starts to break down and flake away.
* [[http://scp-wiki.wikidot.com/scp-058 SCP-058]] resembles a ''bovine heart with tentacles and spikes''. It also talks, although whether that's a good or bad thing depends on how creepy you find poetic ranting.
* [[http://scp-wiki.wikidot.com/scp-290 SCP-290]] reads like a love letter to the BodyHorror sub-genre: it reconfigures your body in wild ways while keeping you alive. The Experiment Log Addendum includes the poor test subject's head "slowly embedding itself into his thigh, both eyes absent", and a strong implication that -- horribleness warning -- the restructuring of his internal organs had re-routed some of his waste through his chest cavity.
* 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.
* [[http://scp-wiki.wikidot.com/scp-775 SCP-775]] are ticks as big as nickels.
** "[[spoiler: Hosts will eventually be fully hollowed out, with only the outer layers of skin remaining]]." Thank you, SCP, because [[{{WhyDidItHaveToBeSnakes}} regular ticks weren't horrible enough.]]
* [[http://scp-wiki.wikidot.com/scp-370 SCP-370]] is an memetic hazard that spreads via sight, knowledge about said hazard, sight of the end result, etc. Don't read it if you plan on getting sleep.
** Not to mention that it's implied to be created by [[GodIsEvil God]].
** Furthermore, people infected with it rewrite the page to spread it. How do you know you haven't been infected yet?
* [[http://scp-wiki.wikidot.com/scp-781 SCP-781]] is a person who involuntarily manifests his own nightmares, and is killed by them an average of three times a week.
* [[http://scp-wiki.wikidot.com/scp-035 SCP-035]], a comedy mask that constantly secretes a corrrosive substance from its eyes and mouth. This calls for a glass containment since glass dissolves slower than everything else. People that see it want to put it on and when they do they are possessed by it as their body slowly decays, even past the point where (mechanically) they shouldn't move. The entity has complete knowledge on [[MindScrew human psychology]] and uses this along with [[AffablyEvil charm]] and telepathy to [[HannibalLecture convince ''anyone'' to do anything]]. [[ItGotWorse It gets worse]]. After a while, they decided not to give it any more hosts, realizing the potential this thing had. It starting driving people around the cell to suicide and depression. They coated the walls with an alloy that blocks telepathic suggestions, and it started decaying the walls with corrosive blood. Now, its cell is almost impossible to enter, due to the dangerous phenomenon within. [[BeyondTheImpossible It gets worse.]] The entity also shows interest in [[OhCrap 682]], whose regenerative abilities could counter the mask's corrosive decay, giving it a permanent host.
* [[{{God}} SCP-343.]] He's God, how can he be scary? If he's God, that means he is (however indirectly) responsible for the [=SCPs=]. Possibly including [[OmnicidalManiac SCP-682]].
** Now, now, in 343's defense, he/He denied having anything to do with 682, and in fact cannot see it. This gives a new level of terror. 682 vs. 343, and 682 would win.
*** 682 charged right through 343 without either of them noticing. Neither one can directly sense the other in any way.
** It's pretty clear that 343 isn't "God", just an incredibly powerful being. Plus, God [[http://www.scp-wiki.net/gdp2-second-language is not feeling like himself these days.]]
** Either way, he can't touch 682 and is still more than capable of messing you up something fierce. 343's exact identity is left reasonably open-ended, so the reader can draw their own conclusion.
* [[http://scp-wiki.wikidot.com/scp-966 SCP-966]]; an invisible humanoid ''thing'' that hunts by making you unable to sleep. Imagine it; you're in your house, at 2 AM and you are dead tired, but for some reason you just can't sleep. The night goes on and on, you keep moving uncomfortably in the bed, and nothing. Comes 6 AM and you have to get up to go to work. The whole day you are just shambling through the world like a zombie, trying desperately to at least have a little nap, but ''you simply can't get asleep''. When you're finally so tired you can't even move, a sharp pain comes from somewhere on your body and all you see ''is your flesh being ripped off with no clear reason as to why''.
** YOU SHOULD HAVE WARNED US ABOUT THE PICTURE. JESUS CHRIST.
** More squick than terrifying, but when someone took a picture of one of those creatures with SCP-978 (the Desire Camera), it showed a picture of two of them ''mating''. Just... try to imagine those things doing that... *shudder*
* Four words: [[http://scp-wiki.wikidot.com/scp-426 I am a toaster]]. God, reading my page is still scaring me.
** To elaborate, I am a toaster that makes people refer to me in the first person. Nobody's ''ever'' been able to refer to me in the third person, no matter what they do or don't know about me. Eventually, they completely forget who they are, and usually die when trying to emulate the functions of a toaster (one person died because she ingested so much bread that her stomach ''bursted''). [[http://scp-wiki.wikidot.com/that-goddamn-thing This short story]] also demonstrates my potential for creepy.
* [[http://scp-wiki.wikidot.com/scp-455 SCP-455]]. A ghost ship.
** It's more like an EldritchAbomination ship. For example: Weird temporal distortions, messed up interior dimensions, not really having any clue what goes in inside, things [[ItGotWorse getting worse]] for exploration teams, and so on and so forth.
** Thank you. I was having trouble putting into words ''exactly how messed up'' this thing ''is''.
* Dr. Bright. Aside what he did to his own brother, he is a god of FridgeHorror. Just look at [[http://scp-wiki.wikidot.com/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation 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.
** [[http://scp-wiki.wikidot.com/forum/t-115448/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation#post-934222 Word Of God]] says that the list is not in-universe. So, although Bright ''is'' an asshole, he's not an completely irresponsible asshole.
** But then again, half the time he ''is'' a monkey, so it kinda makes sense.
** Bright's own [[WhoWantsToLiveForever life]] is a FridgeHorror in and of itself.
* [[http://scp-wiki.wikidot.com/scp-363 SCP-363]], the centipedes that grow enormously in the dark. And not into giant centipedes, but into horrific tentacled monsters. To top it all off, [[spoiler:they have the apparent ability to infect people and [[BodyHorror transform them into more of them]]. One of these infectees are a mobile task force agent, who escaped and is possibly out loose into the world.]]
** Y'think that's bad? [[spoiler: The page says F. Tell is to be stopped at all costs. It does not actually make note of him being stopped. Which turns that "possibly" into a firm "definitely".]]
* [[http://scp-wiki.wikidot.com/scp-632 SCP-632]], a species of tiny, hermaphroditic, self-fertilizing spiders. Their eggs are light enough to float on almost non-existent breezes. When they land on warm skin, they hatch, burrow into your ''sweat glands'' and travel through your blood vessels to your brain. Then they burrow in ''THERE'' so they can feast. This causes a minor headache, which is alleviated by light tapping on the closest part of their head. As they continue, the headache gets worse, meaning the host has to hit their head harder. Eventually this leads to ''caving your own skull in''.
* [[http://scp-wiki.wikidot.com/scp-700 SCP 700]]. There was a hole here. It's gone. Now the hole's back, but the person who fell in is gone.
** [[spoiler:You really want scary? The goddamn face picture on the left MOVES, and it's only action is a quick half-second look directly at you.]]
* [[http://scp-wiki.wikidot.com/scp-096 SCP-096]] is a creature who is docile until you look at it's face at which point it will charge at you and kill you. The bad part about this is this works even with pictures and it will track you down no matter how far away you are. Also there have been pictures spread on the internet and the SCP Foundation is still in the process of removing them.
** To understand how horrific this is read [[http://scp-wiki.wikidot.com/incident-096-1-a Incident-096-1-a]] in which SCP-096 tracks down someone who saw it's face in a picture in which its body was only 7 pixels. So you can be looking at a picture and never notice it's there.
** Oh, and did we mention that when enraged, it's invincible? And that it's capable of bringing down an AWACS plane? And that it doesn't just kill its victims, it also [DATA EXPUNGED] them, leaving no trace of the body?
** There is one bit of good news: [[spoiler: -096 has been scheduled to be terminated.]] Though it took [[spoiler: letting the creature escape and wreak havoc on a highway, a small population center, and a military aircraft, ending with the execution of the scientist who arranged for the breach to happen]] to convince the [=05=] to act.
* You know you're dealing with some master writers when they can make ''cups'' ParanoiaFuel. [[http://scp-wiki.wikidot.com/scp-198 SCP-198]], a cup that can teleport and pretend to be other beverage containers. When you pick it up, it instantly bonds with your skin and cannot be removed, even by amputation. You rapidly become dehydrated unless you drink from the cup. What's in the cup? Human body fluids, like spit, sweat, bile, mucus, and...some less pleasant ones. Also, since you dehydrate so fast, your only hope is to chug everything in the cup constantly. I'd make a 2girls1cup joke here, but I doubt it would help.
* [[http://scp-wiki.wikidot.com/scp-182 SCP-182]]: A nice, cheerful guy who wants to be friends. Oh, and did we mention that he's deaf, mute, and horribly scarred, and he compensates for the first three by involuntarily riding shotgun on your senses when you get within ten meters, and if you stay around him there's a 97% chance you'll go insane? And he knows this. And he can't do a thing about it.
* [[http://scp-wiki.wikidot.com/scp-478 Well, how bout the Tooth Fairies?]]
* [[http://scp-wiki.wikidot.com/scp-600 SCP-600]]. The things it does with victims... Do Not Want.
** Not to mention the picture, which in a real-life context as a mugshot would represent in a detached manner a degenerate white trash sex offender and/or serial killer, while it screams, especially with its eyes, to this troper, "CompleteMonster with RAPE FACE!"
* [[http://scp-wiki.wikidot.com/scp-084 SCP-084]]. The static tower. It causes distortions of reality within its area of effect, trapping a small town within. They can't die, age, and have no need to sleep or eat. They also can't escape. One man was picked up four hundred meters from the city limits. He'd been traveling for ''six years''.
* [[http://scp-wiki.wikidot.com/scp-616 SCP-616]] is a prototype airplane. The emergency door opens on its own every 30 days, revealing what is essentially implied to be Hell. However, the worst thing you can do is let the door ''close'' before the manifestation is over...
** As scary as that entry is now, it was actually a lot worse when it was first written. [[http://replay.waybackmachine.org/20090316131454/http://scp-wiki.wikidot.com/scp-616 See for yourself.]] Among other things, it tells you exactly what was on the recording.
* [[http://scp-wiki.wikidot.com/scp-456 SCP-456]] are bedbugs. When they bite you, they produce narcotics in your brain, causing you to feel increasingly sleepy until you sleep constantly, causing you to die of malnutrition. They can't be distinguished from ordinary bedbugs, and you probably won't know they're 456 bedbugs until it's too late.
** Even worse, they exposed four D-class to the bedbugs. After expending three of them, they put the fourth one on a regimen of IV nutrients, blood transfusions, and narcotics antagonists. He's been asleep for a long time. The number of days is blanked out, but it's a triple digit number...
* [[http://www.scp-wiki.net/scp-686 SCP-686]] By itself, it's not scary, but once you think about the implications, you will freak out. 686 is just milk, except it contins an infection that causes mammary glands to devlop in mammals, even males. If milked regurlay, the diesase won't advance any further. If left unchecked, however, your ''entire torso will become an gigantic udder.'' Not only that, but because you have to eat all the time to keep your metabolism up, ''you'll become nothing more than a docile animal.'' Just imagine what a sick mind could do with that. On the other hand, you could consider it FetishFuel.
* [[http://scp-wiki.wikidot.com/scp-860 SCP-860]] seems fairly ordinary by SCP standards - a blue key that leads to a blue-misted forest with some unseen creature stalking you as you walk through it. The ''real'' chiller is the end of the last exploration log and that very last bit of audio.
* [[http://scp-wiki.wikidot.com/scp-624 SCP-624]] seems on the surface to be one of the more benign SCPs. It is an ordinary MP3 player which, if used, plays the users favorite music, covered by a more musically talented version of the user. But if someone with no musical preferences uses it, it plays the users soul. Meaning that you hear everything you have ever felt and heard and thought, including the bits you are ashamed of, right up to and including your own death.
** Death nothing. The examples provided in the main SCP page for 624 state the last track continues ''into the afterlife.'' Specifically, continuing ''as the soul is tortured in hell.'' This happens '''Twice.'''
* [[http://scp-wiki.wikidot.com/scp-750 SCP-750]] is a pair of contact lenses made by The Factory. When you put them on, it displays a variety of changes, like food becoming piles of limbs and gore, walls becoming coated in biofilm, and the skies becoming red and black. Victims who have the glasses on for too long usually get schizophrenia or PTSD. Real scary part? The lenses LET YOU SEE THINGS AS THEY REALLY ARE.
* Goddamn it, the whole ''website''. The titles are very mundane numbers and stuff, so...you never know if you're clicking on something funny, [[{{Squick}} squicky]], or an insanely [[HighOctaneNightmareFuel fucked-up]] EldritchAbomination that will keep you awake for ''days''. And the ''pictures''...oh, god, the pictures...
* According to [[http://scp-wiki.wikidot.com/document-recovered-from-the-marianas-trench 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....
* How about [[http://scp-wiki.wikidot.com/scp-528 SCP-528]]? They're little plastic containers containing silly putty that copies whatever image of a person is pressed onto it. Sounds harmless right? Wrong. Whatever happens to the picture happens to the person. The tests are horrific, the first one involving a D class having first his arm stretched unnaturally long, which is apparently painful and then torn off. The second subject is crushed into a ball and suffocates on his own flesh. The third one however is the worst of all. The putty is dipped in boiling water and the D class actually melts until he suffocates on his own nose.
* [[http://scp-wiki.wikidot.com/scp-736 SCP-736]]. It's [[CommandAndConquer Tiberium]], except that it ''feeds on your blood.''
* [[http://www.scp-wiki.net/scp-939 SCP 939]]. Read the whole page and all its included documents. [[spoiler:They are these ''things'' that attack people and breathe amnesiacs. Doesn't sound scary? Read the document, "Reproduction of SCP-939." The whole thing. The audio log is a blend of HighOctaneNightmareFuel, TearJerker, and just a bit of AdultFear. Those things are sentient and, when they're young, they ''are just like small human children''.]]
** The worst part? Putting them into 914 on "Fine" and "Very Fine" ''killed'' them–in essence, they're '''supposed''' to be dead.
* 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. Maybe it's just me, but I find that terrifying.
* [[http://scp-wiki.wikidot.com/scp-772 SCP-772]]. More BodyHorror, except this time with bugs the size of your thighs.
** Elaboration: They're wasps, MadeOfIron to an extent where bullets and even ''fire'' are useless, with a stinger longer than they are. When they sting you, they inject eggs under your skin, which is described as being 'excruciatingly painful'. Read the whole thing, if you can stomach it.
*** It's also implied that they're more likely to go after you the more afraid of them you are.
* [[http://scp-wiki.wikidot.com/scp-592 SCP-592]]. It's a history textbook. From an alternate timeline. If you read it, you're absolutely fine, as long as you read about something that happened before June 15th, 1956, when the timelines diverged. Anything past that and your mind is warped -- you start remembering things according to the alternate timeline's history, not reality. Reading an entry covering within 2 months from June 15th, you get a headache and can recover. 2 years, you'll have panic attacks and minor mental illness for the rest of your life. 10 years, psychosis and dementia. Anything past that and your perception of reality starts to break down completely.
** It gets worse. People who start remembering history differently due to this book can be ''physically modified'' to match the book's history -- gaining scars and losing limbs in wars that never happened, for example. Worse still, a significant number of the articles mention known SCP objects, suggesting the divergence point is [[spoiler: the founding -- or rather, lack thereof -- of the SCP Foundation.]] (The timeframe is actually spot on for this theory.)
** The Foundation is using a complex system of computers to analyze the book, due to nearly anyone even looking inside the book going absolutely stark raving mad. They are effectively getting the computers to "learn" that history and tell us it in the most vague terms possible. One of the final entries on the page suggests something far, far more sinister is at work:
--> ''The image contains two (2) ADULT PERSONS standing, one (1) HUMAN CHILD sitting on a CHAIR or STOOL, and SCP-███. With 100% certainty the PERSONS in the image should have FACIAL FEATURES. [[TheBlank With 100% certainty the PERSONS in the image do NOT have FACIAL FEATURES.]]''
* [[http://www.scp-wiki.net/scp-930 SCP-930]]. It's an uncharted island. The birds around it, 930-1 attack anyone who gets close. They don't kill, just cause minor wounds. They're not trying to hurt you, they're trying to get you away from the island. There's something much worse there...
* [[http://scp-wiki.wikidot.com/scp-716 SCP-716]]. On the surface, it doesn't seem too scary- just some kind of ghost train, but that's until you get to the part about a boxcar filled with dead horses, or a tanker filled with human bile. Plus there's the fact that if it comes near you ''you're compelled to kill yourself''. And if you're on board the train when it gets too fast, it's likely that you're sent to another planet to die.
* [[http://www.scp-wiki.net/scp-870 SCP-870]]. Ever drop something and can't find it again?
* '''[[http://www.scp-wiki.net/scp-1000 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...
** And later on, they leave us this message:
--> [[spoiler:we forgive you;]]
--> [[spoiler:given choice for now, not forever;]]
--> [[spoiler:let us back in]]
* [[http://scp-wiki.wikidot.com/scp-517 SCP-517]] I became paranoid after having seen one of the pictures move (having been a .gif), so I have a tendency to quickly copy and paste the link to a picture to check if it'll spaz out in any way. The picture with the glass is a .gif, so I didn't stick around long enough to see if it would move.
* Why are all old photos in black and white? Not because we didn't invent color photography until relatively recently. Because [[http://www.scp-wiki.net/skybluesky we didn't invent COLOR until recently.]]
** Although that could become NightmareRetardant when you remember that that was the premise of one of [[CalvinAndHobbes Calvin's father's]] LittleKnownFacts.
* [[http://scp-wiki.wikidot.com/scp-993 SCP-993.]] It's like CandleCove as done by a MonsterClown - except Candle Cove didn't [[BrownNote brainwash children]]. In one episode the clown just stares at you. [[NothingIsScarier For the entire episode.]] What makes it worse is at in that next episode you can tell who he's really staring at: [[spoiler:''The SCP Foundation''. '''''[[ItCanThink It can think.]]''''' It is a sentient, evil ''television program'' and it knows who's watching. Even it's ''archived copies'' are aware. It knows the Foundation is blocking it's broadcasts and ''[[VillainousBreakdown it's pissed]]''. It's copies are kept on the Foundation, so he could easily learn about a memetic hazard and ''get creative...''.]]
** It already knows about certain SCP's, and how to breach containment for them. For all we know, [[OhCrap it may have already found one]]
** One short story on the site makes Bobble even scarier with TheReveal that [[spoiler:Bobble isn't just a television program. It's an EldritchAbomination that existed since the dawn of humanity and has spent all that time encouraging violence in humans. Its first act was to teach them the secret of fire. "Bobble" is just its most recent idea.]] In the same story, Bobble also reveals that [[spoiler:he's perfectly capable of killing people in the real world even in containment.]]
** Of course, the fact that its second-most-recent episode is entitled "[[ClusterFBomb FUCK YOU! FUCK YOU! FUCK YOU!]]" and is basically 30 minutes of extremely angry shouting from Bobble makes things a bit funnier.
* [[http://www.scp-wiki.net/scp-611 The living toothpicks...]]
** To elaborate: They are a species of botflies. Botflies are insects that nest in human flesh, with their larva feeding off the person and eventually burrowing out. These particular flies can impersonate toothpicks, and lay their eggs in the gums, eating their way out. [[{{Squick}} And there's a picture.]]
* [[http://scp-wiki.wikidot.com/scp-1100 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 [[EverythingTryingToKillYou plants, wild animals livestock and even pets]]. [[spoiler: It's implied that [[GaiasVengeance the Earth itself]] is creating the substance.]]
* The [=SCPs=] that [[WouldHurtAChild specifically target children]] really creep me out. 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...
* [[http://www.scp-wiki.net/scp-136 SCP-136]] is a doll. When you look at it for too long, you get {{mind rape}}d (in a way heavily reminiscent of ''physical'' rape) by a naked, insane, blood-covered ghost thing that inexorably floats towards you, laughing, before shoving its face right ups to yours and screaming before disappearing. It usually takes the form of a woman with an obscenely large mouth and oversized breasts. And now we're finding out that it can kill people...
* Dr. Wondertainment, and the fact that his/their SCPs are ''made for children''.
* [[http://scp-wiki.wikidot.com/scp-953 SCP-953]] is pretty freaking scary. The interview with one of the Foundation agents who encountered it is... yeesh.
* [[http://scp-wiki.wikidot.com/scp-089 SCP-089]] is a golden idol with a cavity in its chest that either causes or can prevent horrifying disasters; either way, they will only abate if Protocol M8 is fulfilled. What is Protocol M8? The statue names two people: SCP-089-A and 089-B. The foundation will send out a taskforce to convince 089-B to complete Protocol M8 out of her own free volition. Then comes the WhamLine. [[spoiler: "For each locution event, SCP-089-A is a healthy, unblemished human infant or child between eight months and six years of age, and SCP-089-B is that child’s natural mother. In all documented cases, at the time of the locution event SCP-089-B is alive, healthy and experiences a strong bond of trust and affection with SCP-089-A. Following SCP-089-B’s placement of SCP-089-A in the cavity and the ignition of the inflammable materials, SCP-089-A will burn and be destroyed over a period of two to five hours."]]
** Worse still, they haven't yet found someone to carry out Protocol M8 for the most recent prophecy, which is naturally hidden behind a "DATA EXPUNGED." In the past, when it took 49 days to find someone willing to carry out the protocol the casualties were in the thousands. (It's implied they could have been much worse.) By the date shown on the page it could be up to nearly '''12 years''' since the most recent prophecy. [[hottip:*:Which could be anything, including climate change, the war on terror, the global economic crisis, the Haiti earthquake, or the Japanese tsunami.]]
* [[http://scp-wiki.wikidot.com/scp-1042 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... [[spoiler: 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 minor accidents. Wait, did I say minor ? Sometimes they cause LETHAL accidents. AND THEY KNOW THEY'RE BEING WATCHED BY THE SCP AGENTS.]]
* And for Nightmare Fuel it is really hard to beat...[[http://www.scp-wiki.net/ethics-committee-orientation 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.
* And the [[http://scp-wiki.wikidot.com/and-then-i-died2 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.
* [[http://www.scp-wiki.net/scp-435 SCP-435]] is a meteorite to which a ''[[AlienGeometries very]]'' strange entity that is seemingly immaterial, yet does horrible things to solids that it touches, is bound. Also, if the meteorite isn't illuminated at all times, it can move around. We aren't told what happens when it intersects with landmasses or water, but apparently when it happened during its retrieval it had to be passed off as ''a nuclear test misfiring''. Apparently [[spoiler:it's an EldritchAbomination [[SealedEvilInACan sealed]] to the meteor who cannot see in the light, so he cannot find his way back unless it's dark, and the entity is its ''shadow'' on the material universe. Oh, and if it it goes dark for more than 90 seconds, it could [[ApocalypseHow cause an XK-class scenario]], and the backup plan is dumping the rock in another universe, which might actually break the seal.]]
* [[http://scp-wiki.wikidot.com/scp-710 SCP-710]]. Entering this city will cause you to ''slowly fade from existence.'' And it's totally irreversible once the symptoms manifest, to boot!
* [[http://www.scp-wiki.net/scp-515 SCP-515]] is a young man who causes celestial objects to move towards earth whenever he moves any part of his body. The good part is that he is asleep and is easily constrained, the bad part is that he sleepwalks and his very breathing counts as movement. The sheer impact SCP-515 has on this troper is that not only is it causing a potentially world-ending scenario, it isn't even trying to do so. In addition the feeling of inevitability really nags away on you.
* [[http://scp-wiki.wikidot.com/scp-895 SCP-895]] is not really all that scary to read about. A little chilling, but the really scary thing [[spoiler: is that live video feed. Watch it. [[SchmuckBait See what happens.]]]]
* 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 it's 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.
* [[http://scp-wiki.wikidot.com/scp-017 SCP-017]] is a shadowy figure roughly the size of a young child. Unlike some other dangerous SCP objects, it generally remains stationary and does nothing to actively harm anyone... until a shadow is cast upon it. When that happens, it will immediately leap at and engulf the object or person, then return to normal size as if they were never there to begin with. And all of the Foundation's attempts to discover what, if ''anything'' is within those shadows or where the victims go has been unsuccessful.
* [[http://www.scp-wiki.net/scp-020 SCP-020]] is a germaphobe's nightmare-- a mold that is invisible to humans unless videotaped or photographed, can grow all over your house and ''even on your body'', and changes your personality to make you more sociable so it can spread to all your friends.

* 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 assault 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.
** Nah, I think the crowning piece would be that little bit on that page about Tvtropes: "Human Resources is encouraged to draw upon personnel drawn from [[http://scp-wiki.wikidot.com/scp-4445-j SCP-4445-j]] in first-stage recruitment for personnel, D-Class or otherwise." Hello, future D-class personnel.
** No. The worst one are the ones that say something like "Due to the nature of this SCP, it cannot be contained."
* [[http://scp-wiki.wikidot.com/scp-583 SCP-583.]] Good luck watching SesameStreet again.
** I dunno, I think there'd be an upside to it. For example, I'd enjoy Fox News, Reality TV, etc. a lot more once I'd watched that tape.
* [[http://scp-wiki.wikidot.com/scp-280 SCP-280.]] It attacks people and rips them to shreds... for ''no reason.''
* [[http://scp-wiki.wikidot.com/scp-173 SCP 173]], the statue that tries to kill you if you break eye contact with it.
** Enlarge that page's picture to get a better idea. Enter the jibblies.
** 173 appears to be ''the only thing 682 is afraid of'', as when it was locked inside 173's chamber its first response was to huddle in the corner farthest from 173 and stare at it without blinking for several hours. When snipers popped 682's eyes from afar, it responded by growing bullet-proof eyes all over its body so that it could keep 173 from getting close to it.
** For extra nightmares, think on this: As long as you look at it, it's a harmless statue with entirely curved edges, no claws or anything, made of [[strike:papier mache and therefore probably very light]] concrete and rebar, so it shouldn't be able to move. So... what is it when you're not looking at it?
** Also: [[http://scp-wiki.wikidot.com/revised-entry this short story.]] What would happen if said statue replicated. Exponentially.
** Said entry describes 150 SCP-173s attacking and ripping apart ''SCP-682. The fucking indestructible lizard.''
** [[http://www.youtube.com/watch?v=UBLIAasOfxk This video]]. The statue in action.
** Seriously, [[BrainBleach its appearance is what makes it terrifying]].
** [[http://scp-wiki.wikidot.com/scp-232 SCP-232]] falls into a similar vein. It's a statue of a Sumerian goddess that will cut you up if you allow any shadows into its constantly-lit containment area.
** Also: [[http://scp-wiki.wikidot.com/scp-978-extended-test-logs When SCP-173's picture was taken with SCP-978,]] there was no change[[hottip:*:Pictures taken with SCP-978 show what the picture's subject wants to be doing at the time of the picture]]. Think about it. [[spoiler: SCP-173 ''is exactly where it wants to be''.]]
** Isn't being where it is now significantly better than the alternative? The Foundation can at least try to keep it contained while it's where it is.
** Or it just might not be sentient. Which may be worse, as that means it does what it does for no reason at all.
** Even non-sapient creatures like animals tend to show some kind of change when photographed with SCP-978. The most horrifying possibility of all is that SCP-173 is either not alive, or a living being that lacks any form of consciousness or will whatsoever, ''yet continues to kill!''
** Tropers, you seem to have forgotten about [[http://img822.imageshack.us/img822/4066/tblink.jpg this]] comic. NothingIsScarier until it's smiling on your face.
** They've tried [[WhatAnIdiot duplicating]] SCP-173 with SCP-038 (a tree that can copy anything short of two hundred pounds). The good news? It stopped short of two hundred pounds, so only the head, right arm and upper torso was copied, and it moves so slowly that they didn't notice it during testing. The bad news? It ''didn't stop moving'' when it was observed. This thing is supposed to be a perfect copy of the original; how could we stop it if it just decided to ignore its one supposed weakness?
** Perhaps SCP-173 is just [[spoiler: putting up an act of being able to move only when not observed. The clone could have either not come to the conclusion the original one did, or just attacked because it felt like that was its last resort.]] What's horrifying about this is the implication that SCP-173 could [[spoiler: attack anyone, at anytime, but it's just '''messing with you.''']]
** And worse, it sounds, suspiciously like [[{{Doctor Who}}another creature that moves when you don't look at it that is a statue...]]
** In the game "Containment Breach", you have to run away from it, among other SCPs. And if you encounter it, and you close a door in between SCP-173 and yourself? [[spoiler: It ''opens the fucking door'' and resumes chasing the player. There is literally ''no way'' to stop it]].
* [[http://scp-wiki.wikidot.com/scp-106 SCP-106]] "The Old Man". An entity resembling a rotting old man. It causes severe corrosion and decay of whatever it touches. It drags its victims into its pocket dimension (which it seems to have complete metaphysical control over) and slowly tortures them for hours or days, before ejecting their mutilated bodies back into this world. Take a look at the page [[http://scp-wiki.wikidot.com/scp-106 pictures]]. As if that wasn't enough, it's completely indestructible and almost impossible to successfully contain.
** Finally, someone agrees with me. Not even making jokes about it and [[http://scp-wiki.wikidot.com/scp-033 SCP-033]] helps with the horror.
** ''"SCP-106 appears to prefer human prey items in the 10-25-year-old age bracket."'' Aside from how horrifying ''that'' is, I don't even ''want'' to know how the Foundation discovered this.
** The procedure for its recapture is, if possible, more terrifying than it is. Namely, taking a human in said age bracket and injuring them by breaking a bone or cutting a tendon, placing them in a cell, and broadcasting their cries to lure in SCP-106. If SCP-106 isn't taking the bait, ''additional damage'' is inflicted. If it still isn't working, more "prey" objects are brought in. ''Hoe-shit.''
* [=SCPs=] [[http://scp-wiki.wikidot.com/scp-076 076-2]] and [[http://scp-wiki.wikidot.com/scp-682 682]]. Both are indestructible, very sharp killing machines. Sure, you can put them down for now, but they'll just come right back again in a few minutes.
** SCP-076 has a long description on its page about how in "the worst breach to date", its containment site was forced to set off a nuke, killing everyone and incinerating the location... '''[[NighInvulnerable and failing to kill the SCP]]'''.
** SCP 682 is described as a reptilian monster able to mutate and regenerate body parts, with hyperintelligence, and [[OmnicidalManiac a hate of all forms of life]], and the ability to adapt to anything. It's still capable of talking (usually in the form of obscenities and threats) with as much as 80% of its body mass destroyed, and needs to be kept in an acid bath so as to constantly keep it weakened. What makes it worse is the fact that they have to experiment with other [=SCPs=] to try and find away to permanently destroy it. The most frightening thing? It usually fails, and then it becomes immune to whatever they tried.
** How about the interaction between 682 and 826? [[http://scp-wiki.wikidot.com/scp-826 862]] is a pair of pewter dragon statues that transform the room it's in into the setting of any book placed between them. If the people fail to escape the room, they will lose all memories of their past lives, and the story will rewrite itself to incorporate them. Realizing this, the SCP wrote a 12 page short story called "The Generally Nice, Friendly Thing That Can And Will Kill SCP-682 Permanently if it So Much As Spots That Damn Lizard", that was just a description of a plain green field, and a large monster whose sole descriptive quality was the stated ability of permanently killing 682. So, they put 682 in there, and in a matter of minutes, the plain green field turned into a scorched crater-filled wasteland, and the 12 page short story had become a [[strike:1,000+]] 209 page epic called "The Generally Nice, Friendly Thing That Tried To Kill SCP-682 Permanently But Failed" describing the epic battles between this monster and an innocent creature whose very existence was based around its ability to destroy 682. And 682 won. [[TearJerker Poor thing]].
** Yes, that's right. They wrote a story about something that ''specifically could kill 682'', and 682 ''killed it''. That's how unkillable the bloody thing is.
*** What makes it worse is [[http://scp-wiki.wikidot.com/scp-343 SCP-343]] will not get near 682 and calls it an abomination.
*** [[WordOfGod Dr Gears]], 682 creator, says that, in his view, 682 wants to kill everything because, through his eyes, life on this reality is so utterly ''wrong, disgusting and frightening'' to him that his only response is to destroy everything. It makes you wonder just how his homeplace looks like...
*** Sounds to me like a ''VisualNovel/SayaNoUta'' crossover waiting to happen. The human staff would like her fake form, 682 would like her real one, and until she destroys the planet everyone wins!
*** And SCP-053 ''likes'' the thing! It even seemed to like her back, actively trying ''not'' to scare her when they first made contact and even letting her draw on it with her crayons. Although SCP-053 looks and acts like a three year old girl, everyone over the age of three has an irresistible desire to kill her after ten minutes of exposure, and everyone who tries dies painfully. Perhaps SCP-682 feels the same way about humans as humans do about SCP-053. In which case, one wonders where 053 ''really'' came from...
* [[http://scp-wiki.wikidot.com/scp-689 SCP-689]], which will not only kill you if you break eye contact with it, it will teleport to you, and anybody who sees it now will also be in danger of death.
* 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 SchmuckBait, with the full knowledge that they'll ignore their orders and do something stupid... just so that the scientists will see what happens.
* [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] is a clockwork... thing that grows by absorbing all nearby metal objects and can brainwash anyone nearby into "feeding" it. [[http://scp-wiki.wikidot.com/scp-271 SCP-271]] is an engraved coin, whose inscription spreads to nearby objects and turns them into an indestructible metal with unknown properties. Accidental tests on living organisms suggest that both being absorbed by the machine and being converted by the coin are excruciatingly painful. There is an obvious reason these things are not to be allowed in the same room. The Church of the Broken God wants to try it out.
* [[http://scp-wiki.wikidot.com/scp-002 SCP-002]] is a ball of flesh with a door in it. Through the door is a modest apartment, complete with furniture made out of the body parts of the people it's killed.
* The old [[http://scp-wiki.wikidot.com/scp-112-arc SCP-112]] is an ArtifactOfDoom activated in the presence of any non-virgin or non-castrated person. And it has been stolen by radical Muslim terrorists. Get the idea?
* [[http://scp-wiki.wikidot.com/scp-415 SCP-415]], The Harvested Man. ExactlyWhatItSaysOnTheTin.
* [[http://scp-wiki.wikidot.com/scp-231 SCP-231-07]], a girl of undefined age who was impregnated with some kind of CosmicHorror by a Satanic sex cult. The only way to keep it from being born is by putting her through "Procedure 110-Montauk" every twenty-four hours, which is described as involving "brutally (DATA EXPUNGED)". Since it can only be carried out by convicted sex offenders among Class D Personnel, and is being supervised by employees who have passed a psychological examination in which "mild sociopathic tendencies and marked sexual deviancy are not to be considered automatic fail conditions" (an early warning and implication of who carries this out) it's [[strike:pretty obvious what it is]] [[WordOfGod 10 times worse than whatever you think it is.]]
** Here's one bit of extreme Nightmare Fuel relating to SCP-231: Some of the staff who were involved in the project have taken amnesiacs to forget it, and false memories have been implanted. Which means that ''you'' could have been on the project and not even remember it.
** Oh, and they started using amnesia-inducing drugs on 231 herself; the sum total of 110-Montauk was starting to induce a form of shell shock in the victim. As a constant level of agony and terror needs to be inflicted to supress the EldritchAbomination, they started wiping her mind of her knowledge of Montauk. Eventually it was determined that a weekly dosing cycle was most efficient, as the 3rd to 4th time is the most mentally devastating; the first time is horrible, the second time establishes a pattern, and the third confirms that [[DespairEventHorizon this is what the rest of your life is going to be like.]]
** The article contains an addendum added by one of the heads of the SCP foundation specifically stating (presumably to set straight employees having second thoughts about all this) that while "Procedure 110-Montauk" is quite possibly the most horrifyingly evil thing the SCP foundation has ever been involved in, failure to carry it out will result in the EndOfTheWorldAsWeKnowIt, judging by the death tolls that ensued when SCP-231-01 through SCP-231-06 gave birth. Sweet dreams.
** The specific age of SCP-231 is not specified, only a minimum and maximum, both of which are censored in the article. But the minimum is a single-digit number.
** And to make matters worse, it was originally just a censored two-digit number, but after a troper breathed a sigh of relief that at least 231-7 was not a child, the Foundation saw it and changed it, [[TemptingFate and replied to that post with "this is your fault,]] [[NiceJobBreakingItHero you made this happen".]]
** In such fine print that you may have to View Source to find it: [[spoiler:"Don't believe it when they say they're trying to save her. Why would they bother? They've got exactly what they want exactly where they want it."]]
** They're going to have to come up with ''something,'' though, because even barring any changes in her situation eventually she's going to die of natural causes, and the death of the previous six 231 hosts released their whatever-it-is. Since it wouldn't really make her situation much worse than it already is, putting her in something like the other SCP which is an iron maiden which prevents the victim aging or dying could delay the problem, but she'd still age while she was outside it for the Procedure, so it still wouldn't work indefinitely. Not to mention her [Data Expunged] may interpret that as an attempt to kill her and figure it was time to do its thing. And being fed via IV doesn't exactly prolong life, so they probably have less time than the average lifespan. Also, think about this; does she know what the thing she's carrying is, and would it make her situation worse or better if she did? If she did find out, either she may think "oh well, it'll prevent something even worse happening" and her distress level will be lowered slightly, which, since the distress level appears to be the important part of the Procedure, will be a problem, or she'll want to release the thing for revenge purposes. Pity the portal into a world already undergoing zombie apocalypse is no longer open, as they could have just shoved her through there - that world is already ending, and she'd no longer be the Foundation's problem. 231's situation, to me, is just plain {{Squick}}. The Nightmare Fuel aspect comes into play with the fact that they're keeping this thing under control using either the minimum safe or the only way to do so, ''they don't have a backup plan, and since the previous six hosts are all dead they don't have a way to safely test any plans they do come up with.''
** I have a WMG over on the WMG page to explain why they don't have a backup plan and why she "stays perpetually young".
** Alternately, imagine being part of the support staff for the 231 containment site. Knowing what you're ordering done to the girl, watching it every day, obtaining supplies and materials to enable it, terminating anyone who tries to stop it. There's a reason why so many people associated with this thing commit suicide.
* One of the most disturbing things about the SCP series (for some) 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.
* Even the [[http://scp-wiki.wikidot.com/scp-series#toc12 joke SCPs]] are creepy. Take [[http://scp-wiki.wikidot.com/scp-000-j SCP-000-j]], for example. It's a catalogue of every SCP item, which anybody can apparently order through a simple phone call as if they were everyday items. When one of the testers did call and order one of them (a safe-level item), it disappeared from its storage and mysteriously got delivered to his office, and the amount he would have paid for it vanished from his next paycheck. Now imagine somebody finding this catalogue and ordering one of the Keter-class items...
** Imagine them ordering 682?
* 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.
* The [[http://scp-wiki.wikidot.com/decomm:scp-316-d termination log of SCP-316-D]] is absolutely horrific. Even though he seems to be one of those Gary Stus that pretty much psychically forces you to like him, Surveillance Log x316███ was just gruesome. Also: The thought that he could wake up on a space probe en route to the sun is what most everybody's worst nightmare is made of.
** Given the nauseating levels of Gary Stu-ism given to SCP-316-D, I would argue its death was not nearly nightmarish enough. That said, the only reason the entry remains open is to demonstrate precisely the sort of puerile drivel that should never be added to the site in the first place.
* SCP-001 is generally reserved for the largest and most brickshittingly terrifying SCP concepts, so much so that the users of the site would rather not ruin the mystery by having a single canon SCP-001.
** The [[http://scp-wiki.wikidot.com/scp-001 SCP-001 proposal page itself]]. When you scroll down to see why "SCROLLING DOWN WITHOUT PROPER INNOCULATION WILL RESULT IN IMMEDIATE CARDIAC ARREST FOLLOWED BY DEATH," you will shit bricks. What makes it worse is that the image is designed to kill you. Now if that were an SCP, and it could spread...
** It's not supposed to be scary. The idea is that the patterns in the image are so illogical and confusing that, if viewed without safety measures, will cause the brain to 'crash', so to speak. This is not the first time such a concept has been explored.
** If you're curious that's a randomly generated image from the [[http://electricsheep.org/ electric sheep screensaver]]
** One of the possible SCP-001s. Completely harmless by itself. Its just [[http://scp-wiki.wikidot.com/jonathan-ball-s-proposal a sheaf of stapled papers containing detailed reports of the SCP items]]... except that every time you look at the report, the report is on a new SCP item, which then appears somewhere in the world. Let the sheer terror of that concept work its way into your brain.
** One of the other possible SCP-001s is [[http://scp-wiki.wikidot.com/dr-clef-s-proposal a huge humanoid figure standing in front of what is more or less the gate of Eden]]. Getting within 1 kilometer of it will get you not only killed, but wiped from existence. If it ever goes active, TheEndOfTheWorldAsWeKnowIt will ensue. Making matters worse is that the page includes a transmission from TwentyMinutesIntoTheFuture about SCP-001 waking up and bringing about said apocalypse. Mega-gulp.

** My favourite concept for SCP-001: [[spoiler: [[Wiki/SCPFoundation a massive worldwise organisation that acts like a sociopathic MIB agency]].]]
** Another recent possible SCP-001: a large onyx gemstone with an infinitely fine fractal gold filigree, apparently serving as a lock for an unknown object. Doesn't really seem scary, right? [[spoiler:It turns out that the minute variations in the cosmic background radiation has ''the exact same pattern'' as this onyx lock. It's implied that our universe is contained in a similar object, and possibly the artifact in question. The Foundation is currently trying to [[ApocalypseHow open and/or destroy it.]]]]

Travel counter-clockwise, however, and the path appears to go continuously uphill. [[MindScrew Even if you go all the way around to the start.]] The real horror comes when one reads the attached document from one of the founding Overseers. [[spoiler: Analyzing the Gravel Path led to the initial founders of the Foundation to the initial understanding of bending reality that allowed them to start manufacturing SCP objects. And the Foundation never "found" ''any'' SCP. They ''made'' them. ''All of them.'' -231, -051, -616, -682, all of them ''were created by the Foundation.'']] And the scariest part? [[spoiler: SCP objects are no longer being manufactured. They're just ''appearing'' in containment, with no indication of where they came from, and the Foundation has reached the point of no return.]]
** [[http://scp-wiki.wikidot.com/sandrewswann-s-proposal S Andrew Swan's proposal]] is a masterpiece of MetaFiction ParanoiaFuel. The details are so confidential that even the ''description'' has been expunged and the directives state there is no way of containing it without risking a ''ZX Reality Failure event'' (the destruction of the observable universe). No-one except the O5s is allowed to know anything about it at ALL. But there is a hidden message on the page from a researcher who worked on it and managed to escape the purge detailing it: [[spoiler:The reason the SCP Foundation discourages attempt at cross-referencing [=SCPs=] and looking for patterns in their seemingly random nature is that once, ''they did'' try to develop a Grand Unified Theory of [=SCPs=] and they discovered that reality is constantly shifting, things appearing and disappearing as if they'd never been, even whole sections of the Foundation's history changing. Eventually one of the researchers discovered the pattern- the shifting development of reality "toward narrative coherence, toward a plot..." And they discoverered the truth.]]

* The last line in Baba Yaga's entry was far, far more disturbing to [[{{Tropers/Whitewings}} me]] than poor 231-7's treatment. At least the higher-ups know that what they're doing to her is horrible, and want to find a way to help her. Quote: "While SCP-352 prefers any type of human flesh over any other type of meat, it appears to have a special propensity for children between 0 and 2 years of age. After observation of highly elevated levels of co-operation and a reduced tendency to attack staff while consuming flesh of this type, a possible alteration in the current diet is being considered."
** [[spoiler: No, they ''don't'' want to save 231; in very fine print after the end of Addendum 231-B, you can read: "Don't believe it when they say they're trying to save her. Why would they bother? They've got exactly what they want exactly where they want it."]]
** What, [[http://scp-wiki.wikidot.com/scp-352 this]] Baba Yaga? The Foundation just wants to make her more manageable by [[MoralEventHorizon feeding her toddlers]]. This is less horrifying when you realize that there's an SCP that turns animal flesh into human flesh, and, by logic, baby animal flesh into baby human flesh, but still. Don't tell anybody, they'll probably make an addendum rejecting it.
* [[http://scp-wiki.wikidot.com/scp-507 The guy who randomly teleports to alternate dimensions]], including one that apparently had the Joker who was right in front of him when he turned the flashlight on. "Back so soon?" The poor lad's reaction was probably the same as yours would be. Not to mention "...the spiders...".
** The interview log when another version of that teleporter shows up from an alternate dimension is terrifying. Basically they refuse to elaborate on which one is from the "real" dimension, to keep the other guy safe. At the end, one reveals that "In his reality, Lincoln was killed while sleeping by his then vice-president, instead of by General Lee." The interviewer responds "In our world, Booth assassinated Lincoln." The end of the article just states that "Subsequent testing revealed that SCP-507s abilities have no biological basing, and that severed pieces will still “shift” along with the main body."
** During one of his trips to another reality, 507 arrived in what seemed to be the facility, only in a state of disuse with corpses covered in a strange, breathing mold. Further exploration revealed that possibly ''the entire world'' was covered in the stuff. Upon further inspection of a mold sample 507 brought back, it was found to be very similar to both [[http://en.wikipedia.org/wiki/Cordyceps Cordyceps Fungi]] (some varieties of which basically brain-wash their hosts) and a fungus produced by - wait for it - [[http://scp-wiki.wikidot.com/scp-407 SCP 407]]. The Foundation consequently restricted experimentation with 407, and all known copies were terminated by "Serpent's Hand," but no one is certain if more copies may be found elsewhere.
* [[http://scp-wiki.wikidot.com/scp-294 SCP-294]] is a coffee machine that can dispense just about any kind of liquid. If you value your appetite, do not use "joe" as a synonym for "coffee" when inputting what drink you want, especially if your name is Joe.
** Said machine can dispense "My Favourite Drink", which is tailored to the individual's tastebuds, and "The Best Drink Ever", which causes the drinker to become depressive and commit suicide because "everything else is just a letdown now." For more straightforward ways of killing you, it will happily dispense any kind of acid. There's a ''reason'' why they have two security guards stationed there with orders to shoot anyone who is trying to order anything other than normal drinks for research.
** On the other hand, it also turned out "[[CrowningMomentOfHeartwarming Something Cassie will like]]," a [[HitchhikersGuideToTheGalaxy Pan-Galactic]] GargleBlaster, and a "cup of relevant medical knowledge."
** When asked for something that could kill SCP-682, the liquid was so intense it vaporized the entire site SCP-294 was in, apart from a small patch surrounding the machine. Given cases with other SCPs like this, whether it would've worked is anyone's guess.
* Speaking of disturbing food dispensers, [[http://scp-wiki.wikidot.com/scp-261 SCP-261]] is a vending machine that dispenses snack foods that might be normal, strange or bizarre. As [=SCPs=] go, it's actually pretty fun and not too scary. The disturbing part comes as you slowly read more and more stories about what comes out of the vending machine. The first time living food is dispensed, most researchers refuse to eat it and are as distressed by the idea as most people would be. But as more and more living food items are dispensed from the vending machine, researchers get more and more casual about it, until reports of the living, potentially thinking beings only describe their flavor. As if cramming the recently dead bodies of various cute little alien critters popping out of the machine is the normal and obvious thing to do.
** Another fun result from SCP-261 is "TASTE ME", an obvious reference to Alice's Adventures in Wonderland. It's funny, right until the part when the test subject eats it, goes into convulsions, and dies due to brain expansion. "Analysis of the cake showed large amounts of human growth hormone as well as several unidentified chemicals." Gee, thanks for ruining that book for me.
** Something really horrifying are the products dispensed labeled FOOD and DRINK. People who ate the FOOD became emotionless and dull-witted, while people who drank the DRINK became more and more subservient. Doesn't sound so bad by itself, [[FridgeHorror but think about]] where they might have came from, and what those products are used for there...
** And then there's the can of "Prangles." Once you pop, you can't stop. '''''Ever'''''.
** [[NightmareRetardant It also produced]] [[http://tentaclegrape.com/ Tentacle Grape]].
* [[http://scp-wiki.wikidot.com/scp-835 SCP-835]] was a collaboration between two authors: one of them was the guy who wrote the infamous SCP-231. The other wrote SCP-682. Their goal was to create the ultimate in squicky [=SCPs=]. Some would say they succeeded. For the full impact, read the article first, then the "uncensored" version, then the "uncensored" version of the exploration log.
** SCP-835 also serves as a bit of {{Fridge Brilliance}} [[HighOctaneNightmareFuel Nightmare Fuel]] for the entire SCP series. Now you know what kind of disgusting, freaky things are behind all those (DATA EXPUNGED) boxes, and they're exactly as bad as you'd think. "Now we can be together, just like he wants..."
** That adds sort of a ghoulish edge to several joke [=SCPs=] where [DATA EXPUNGED] was used for laughs.
** And then someone went and added a picture for 835. [[BrainBleach Cripes.]]
* The former [[http://scp-wiki.wikidot.com/scp-995 SCP-995]], an object that is too mentally scarring for many to describe. At best, it's been described as an "Infinite Devil Machine." It's required to be kept in a blessed lead container full of also-blessed holy water, which turns black and darkens whatever room its in. Recorded images of it breaking out of its container show tendrils poking out of its container. Unfortunately it's been deleted due to negative ratings and changed to a device which drives people insane as it touches an electric conductor. Eventually it was deleted altogether, although the original article can still be found [[http://replay.waybackmachine.org/20090317090832/http://scp-wiki.wikidot.com/scp-995 here.]]
* [[http://scp-wiki.wikidot.com/scp-217 SCP-217]] is a virus that turns people into machines. It can affect any animal, replaces organs and such with mechanical parts, and the affected creature becomes repetitive and locked in a set pattern of behaviour. Scared now? Oh and did I also mention that the Church of the Broken God wants to bring it into contact with [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] and [[http://scp-wiki.wikidot.com/scp-271 SCP-271]]?
* The worst one was [[http://scp-wiki.wikidot.com/scp-055 SCP-055]]. Which was also the coolest. Imagine seeing something, and not being able to describe it. It basically makes you forget anything related to it, being reduced to what it DOESN'T look like. [[http://scp-wiki.wikidot.com/incident-report-i-028-f This doesn't help either]]. An area that makes people gain immediate knowledge of a random subject. A man enters the area, goes into a fit, and afterwards forgets he was even in the area. Locked the memory out of sheer horror? Amnesia?
* Someone [[http://scp-wiki.wikidot.com/a-man-at-the-top-of-his-profession 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!
** It's no longer canon.
** [[OrwellianRetcon Of course it's no longer canon.]]
* [[http://scp-wiki.wikidot.com/scp-590 SCP-590]] is (objectively) nothing compared to most of these, but the fact that they purposely destroyed his mind, reducing him to the functional level of a three-year-old -- and for no reason other than to make him more controllable -- chills me to the bone. Worse than that is reading the experimental logs of SCP-978, a camera that shows the photographed subject doing what it desires to be doing rather than what it actually is doing. 590's picture is absolutely heartbreaking and one of the most chilling things she's read on the whole site.
* [[http://scp-wiki.wikidot.com/scp-093 SCP-093]] is my favorite. Read the whole thing, including the test reports, in order, and then read the last link on the page. It sent shivers down my spine; the reports themselves are creepy and unsettling, but the final report is just chilling.
--> [[spoiler:there was no war it was him him him him him IT. IT! it came from between the folds of time and space and worlds and light and dark something that is but should not be slipped in and called out to them as their god and they believed it and they tasted it and touched it and layed with it and became its property and did its will and IT IS STILL HERE]]
* 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.
* [[http://scp-wiki.wikidot.com/scp-899 SCP-899]]. "A psychic and telekinetic phenomenon that most commonly manifests as groups of hostile phantom children." Then they went and exposed it to [[http://scp-wiki.wikidot.com/scp-573 SCP-573]]. To give some hint of how "successful" that experiment was, [[http://scp-wiki.wikidot.com/diary-573 this]] is what happens when a perfectly ordinary person uses 573, and taking a picture of it with SCP-978 resulted in a [DATA EXPUNGED] and a note that "It appears SCP-573 is indeed sentient in any case."
** GOOD GOD THE PICTURES. Seriously, they're [[UndeadChild freaking scary.]]
* [[http://scp-wiki.wikidot.com/scp-604 SCP-604]]. What makes it particularly bad is that it has no apparent effect on the users, meaning they chose to use it ''as they did of their own accord''. There are extensive records of what the thing can do, because its former owners charted their progress. And when they succeed...
---> (a waiter comes in pushing a cart with a wooden box on top. The box has several slots and holes opened in it, and tubes trail out, connecting to IV bags and tiny batteries. A mewling comes from within)
---> (The box is lifted up over a plate, put on it, and then pulled off. There is a flash of some kind of twisted, shaved animal, but then a human head appears.)
---> (the human head is that of a man around thirty five, with thick black hair and sideburns. He has extremely pale skin and dark circles under his eyes. He is severed at the neck, which reveals muscle and a bloody hole.)
---> Head: Where am I? Who am I?! What the hell is going- (Begins looking around and turning up, down, and to the sides) Everything seems at a weird angl- hey, what are you doing! Get that knife away from me!
---> Waiter: Bon appétit, gentlemen.
---> Head: (begins screaming)
* [[http://scp-wiki.wikidot.com/scp-847 SCP-847]]. {{Uncanny Valley}} aside, the "[DATA EXPUNGED]", the attacking of all females in the area, and the victim being killed by 'massive blunt trauma' all lead to some unsettling implications.
* There is something distinctly disturbing about [[http://scp-wiki.wikidot.com/scp-914 SCP-914]]. Testing shows that in spite of its supposed lack of sentience, it seems to have a rather twisted sense of humor, and on multiple occasions the "very fine" setting, which refines something to its most perfect form, has produced a (mercifully inanimate) replica of SCP-682, suggesting that it may have a "thing" for the beast. The fact that it knows 682's "home phone number" doesn't help matters.
** Testing of [[http://scp-wiki.wikidot.com/scp-978 SCP-978]] on SCP-914 indicates that what 914 really "wants" is to have a sixth setting on its control knob, that goes ''beyond'' Very Fine...
** Every time someone tries to run something organic through the "Very Fine" setting, it gets all "[DATA EXPUNGED]". But some of those have rather... telling... notes relating to "cleanup," and they've banned any further attempts to use it on living things.
* [[http://scp-wiki.wikidot.com/scp-342 SCP-342]]. It takes the form of a ticket to some kind of public transit, and once you get on you can never get off. Just... read it.
** "And her never returned, no he never returned, and his fate is still unlearned. He shall ride forever 'neath the streets of Boston. He's the Man Who Never Returned."
* [[http://scp-wiki.wikidot.com/scp-400 SCP-400]] is a phone booth that can contact anyone. [[http://scp-wiki.wikidot.com/scp-519 SCP-519]] is a phone containing a voice that is on permanent Sarcasm Mode. When they tried to ring 400 through 519, 519's response was, and I quote, "Ooooh, boy...". On the other side, 400 rang, and a guard picked it up, only to be pulled apart by an unseen force. Then there was a containment breach resulting in the entire site around being locked down and everyone terminated.
* [[http://scp-wiki.wikidot.com/scp-826 SCP-826]] is a very ordinary looking set of pewter dragon-head bookends, but if you close the door of the room, put a book or DVD between them, and open the door, the doorway will be a portal to the world of the book or film. It seems almost to be a joke entry, with a note about a researcher who was demoted for (apparently) planning to do very naughty things to a female Disney character on a DVD. But what if you tried it with the Necronomicon? And this thing is listed as "safe." Not Euclid, not Keter. "safe." Brr.
** Safe only means that the SCP can be reliably controlled, as long as you have appropriate protocols, and aren't inherently hostile to humanity. This is an easy mistake to make, made worse because the standard definition of safe does apply to some of them. And then others kill you in horrible ways, but are easy to keep under control. Good luck guessing which is which.
** And if you don't find the bookends within the story in time, you can ''never escape''. You get {{Mind Rape}}d into a background character...''forever''. And you can't even choose which part of the story you arrive in. So if you arrive at the very end...tough luck.
** Dear God, imagine what would happen if someone put a DVD copy of MarbleHornets in between SCP-826? ... shit.
** Do remember that even if you put in something so horrible that no one could possibly survive it, its effects will still be confined entirely to one room. All you have to do is warn people not to go in.
* [[http://scp-wiki.wikidot.com/scp-701 SCP-701]]. Especially Incident Report SCP-701-19██ and that photo.
** Granted, that's an unnerving photo. But there's something amusing about how the report is basically a cross between a tenth-grader's meticulous school report on The Scottish Play with a ''literal'' KillEmAll ending.
** The URL for the Incident Report betrays what date 19██ is: [[spoiler:1997]]. Also, the state mentioned as the place where the video tape was recovered is [[spoiler: Ohio]]. It seems those ██s aren't impenetrable after all.
* [[http://scp-wiki.wikidot.com/scp-740 SCP-740]] will make your skin crawl. An infection that eats you alive, and then makes spiders burst out of your skin (Hopefully you'll be dead by then, if not you have about 20 minutes to live). Then they EXPLODE to create more infected with the spores they release.
* [[http://scp-wiki.wikidot.com/scp-610 SCP-610]]: It's like the [[DeadSpace necromorphs]] and The Flood rolled into a single package. Squick warning, obviously; the page image is [[BodyHorror especially bad]] (or [[NightmareFetishist awesome]]).
** Even worse is it`s official nickname: ''The Flesh that hates''.
* [[http://scp-wiki.wikidot.com/scp-439 SCP-439]]: It's a parasitic insect resembling an earwig that will ''[[BodyHorror turn your body into its hive.]]'' It enters your body ''[[ParanoiaFuel while you're asleep,]]'' and then, in a process shown to be ''very'' painful, causes your body to deform into a spherical mass while the insects ''eat you alive from the inside out.''
** And then there's the addendum at the end, which shows an SCP researcher operating on the "bone hive", and finding that the eyes had not yet been eaten. She shined a flashlight on them, and ''the eyes followed the beam.'' Think about the [[AndIMustScream implications.]]
* 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.''
** On the other hand, considering the world evidently still exists, whatever he's doing has worked so far.
* [[http://scp-wiki.wikidot.com/scp-804 SCP-804]]: A piece of "art" that, when activated, slowly but surely kills all humans and destroys all man-made works in an ever increasing radius around it. The only saving grace is that said artwork is not immune to its own effects. However, the most nightmarish element of this SCP isn't its potential to destroy the world. No, the scariest part is that, according to the former lead researcher, Dr. Sorts, [[NotBrainwashed the SCP has no memetic influence on people]]. The people who created and activated a device that would wipe out humanity did it because, in Dr. Sorts' own words, ''they wanted to do it''. That the SCP Foundation transferred Dr. Sorts to another project and is continuing testing for a memetic component means either 1) the Foundation wants to be absolutely sure that no mind control is involved or 2) ''even the Foundation'' doesn't want to believe that there ''really'' are people in the world evil enough to murder humanity entirely of their own free will.
** The people "evil enough to murder humanity entirely" were well-intentioned extremists, at least the original ones who sacrificed themselves. As in, they wanted to get rid of humanity because they thought it had a greater net negative than positive effect on other lifeforms. Meanwhile, the Foundation has terminated or is trying to terminate several lifeforms for the same reason (and real life humans do this all the time with diseases, though with other life the extinction we cause tends to be accidental). So when you think about it, the creators of the SCP-804 merely had the same views on their fellow humans as most humans do on lifeforms that threaten them. You could argue that the SCP-804 creators are more evil because they have betrayed their own species, if you like... or you can argue that their motivations are actually more objective, since their views on what lifeforms are more harmful aren't determined by what benefits their personal continued existence. Either way, thinking about this for long periods of time is a bit like reading SCP-079 (an increasingly rational and objective computer that nonetheless clearly hates humans, if not all life), in that it has a creepy "but what if the SCP is RIGHT?" air to it.
* [[http://scp-wiki.wikidot.com/scp-354 SCP-354: The Blood Pond]]. It's a pond in the Canadian wilderness that is full of a liquid similar to blood. Highly dangerous creatures emerge from it from time to time; most of whom have nothing in common. And according to one SCP agent, it's alive. And intelligent. And angry. ''[[spoiler: And growing]]''.
** The fact that a seemingly normal human emerged from the pond at one point for ostensibly diplomatic reasons and was shot on sight probably didn't help on the "angry" front.
* Nearly every Keter-class SCP could be considered HighOctaneNightmareFuel. Given that the criteria for Keter classification are: 1) it's too valuable, dangerous, or invulnerable to be neutralized at present, 2) it's an extremely significant threat to humanity, civilization, and/or ''reality'', and 3) ridiculously extensive and precisely followed containment protocols are required to keep the SCP isolated and secure (and even then it may only be a matter of time before it gets out of control)...
* [[http://scp-wiki.wikidot.com/scp-120 SCP-120]] is a pink kid's swimming pool that works as a PortalPool, cycling between 11 locations each time you send someone through. The 11 locations include the 5 Lagrange points. Which are in space.
** It's a convenient way of teleporting, though, except for the Lagrange points. So they simply... cause it to cycle through them. Using D-class personnel.
** Also, it was discovered because of "reports of missing children". [[KillItWithIce Think about]] [[KillItWithWater what happened]] [[ShiftingSandLand to those]] [[ThrownOutTheAirlock children]].
* [[http://scp-wiki.wikidot.com/scp-662 SCP-662]] is a silver bell that summons a friendly, polite butler named Mr. Deeds, who will gladly perform required services by asked by the ringer, within reasonable limits. He'll fetch you a sandwich, but not one made of human flesh, and he'll bring you a grenade, but not a nuclear bomb. Seems fairly harmless, right? [[spoiler: Then they asked him to assassinate a D-class personnel, which he did with [[AlmightyJanitor disturbing precision with a buck knife]].]] Suddenly, Mr. Deeds doesn't seem like the nice, friendly fellow we all think he is....
** He might very well be harmless, but read the end of the [[http://scp-wiki.wikidot.com/662-l1 interview log]], and the interrogation by Agent Graves. [[spoiler: So, they kill him thoroughly, perform an autopsy on him, discovering nothing terribly interesting about him, and then they "permit" his body to vanish.]] Shortly thereafter, he is summoned, ready and willing to perform his duties. So, he's nigh omnipotent, willing to perform any service or retrieve any object, within his capabilities, and [[spoiler: he cannot be killed.]]
** I actually think this says far more about the way the Foundation deals with D-Class personnel. They are considered so inconsequential that Mr. Deeds will consider nothing much to kill them. Again, the Foundation is ''almost'' worse than the stuff they contain.
** ''Why'' can't Mr Deeds explain how he does what he does, even under torture, and why does he appear so uncomfortable when asked? The photo of him from the Desire Camera showed him exactly as he was, posing for the photo, which suggests his greatest desire is to do what he's instructed to do. Is he so uncomfortable when asked where he goes and where the items come from because he's unhappy that he's literally unable to explain, or because something worse will happen to him if he does? Also, he was disturbingly calm when offering to be fed to SCP-682.
* [[http://scp-wiki.wikidot.com/scp-668 SCP-668]], [[spoiler: the knife used to kill Kitty Genovese]], is utterly terrifying to people who don't deal well with helplessness. Read about what it takes in order to reclaim it if lost. Now think about what that would enable any garden variety sadistic creep to do. That thing's pretty much a catalyst for a wide variety of end of the world scenarios.
* [[http://scp-wiki.wikidot.com/scp-597 SCP-597]]. [[FreudWasRight The Mother loves you.]] [[MindRape You will love The Mother.]] [[FateWorseThanDeath The Mother will provide for you forever.]] Why this powerfully telepathic...''thing''... has not been terminated or even properly contained is a mystery.
** Probably because it's ''FetishFuel'' for some of the Foundation's higher-ups.
** Let's count everything that's wrong with SCP-597 or "The Mother", shall we? Well, for starters there's what it is, a massive ball of mammaries, nipples for every species of mammal, and no matter what the milk will always be perfect for whatever mammal's drinking it. Most mammals can't resist it. Bats, rodents, cats, dogs, all of these can be found sucking on the thing, and refuse to let go; it's described as being a sexual, psychological, and hunger compulsion all at once. Also, the male staff have sex with it. Regularly. So regularly in fact that they don't do anything to discourage it. The thing is always covered with slobber and semen, which D-class personnel clean. Of course, that just means they get brainwashed faster than everyone else. They also have the task of collecting the milk for study (which they often sneak whole bottles off for themselves). All staff at its facility are affected. In early stages, people who quit smoking for years have a 100% relapse rate, people binge on snacks (especially dairy products) or chew gum. So much gum that they choke on it. Later stages the behavior gets even more extreme. Formerly heterosexual woman begin to engage in lesbian sex, some men become rapists, others latch onto large breasted women as surrogate mothers. If things are allowed to progress this far, all milk samples from The Mother will be fought over by the staff. Next staff begin to regard the mother with superstitious awe, worshiping it with incense, food offerings (even though it doesn't eat) and animal sacrifice. One scientist circled every one of the nipples with a red marker and wrote the word "life" next to them before killing herself. Then they begin to revert into child like states, losing bladder and bowel control, masturbating constantly, calling it "mommy", crawling on all fours and talking like toddlers, before finally curling up and joining the rodents and bats in suckling. The milk will keep them alive the rest of their adult lives, and they will be in blissful happiness, but their muscles will atrophy, and their teeth will fall out, and they will experience digestive problems from the sudden switch to a liquid diet. There is no way of stopping this. Even if you send them away from it, the effects are permanent, and they have several data expunged section describing staff that took this mental illness home with them (including one where it was implied that a man raped and killed his own mother for "not being good enough"). The only thing they can do is constantly rotate, and kill staff members.
** Even worse: The Mother ''can'' be destroyed, but the ones who have the authority to do so use The Mother as a sexual experience, ordering a Class D to pry them off after an hour of suckling.
* [[http://scp-wiki.wikidot.com/scp-087 SCP-087]] is a never-ending platform staircase that resists attempts to illuminate it, and descending one flight of stairs lets you hear a child crying for help about 200 meters down. The people sent down one by one found something else instead...
** Plus, they sent four missions down into that staircase and you can only read the first three and they get progressively worse. But after the fourth mission it started to knock on the 'door.'
** Also terrifying are the effing ''pictures'' on the thing's page. Especially the first one. It's like one of those "when you see it, you'll shit bricks" demotivators.
** And that's not all. If you try to upload the first image to a imagehoster (you know, to avoid hotlinking), the face in the uploaded picture is ''gone''.
** There is now a [[http://dl.dropbox.com/u/10887020/SCP/SCP.zip game]] of SCP-087. Enjoy.
* 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.'' [[http://scp-wiki.wikidot.com/scp-042 SCP-042]] in particular seems to be written specifically to highlight the cruelty of the Foundation, [[spoiler: 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 ForScience. Yeah. It makes me sick too.
** 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.
* [[http://scp-wiki.wikidot.com/scp-596 SCP-596]]. That it can heal any injury would have been a great help for the Foundation, if it weren't for the fact that any physical contact with it will leave the victim permanently stuck to it and unable to move it themselves unless another person makes physical contact with the statue, killing the original subject. What's even more nightmare-inducing is that absolutely no other method can separate the two: whenever a victim is surgically removed from SCP-596, they will die and a new body will grow from the parts still attached to SCP-596.
** What's even worse is how the Foundation takes advantage of its abilities. The victims are used as ''reusable organ donors''. Since anesthetic isn't an option thanks to the SCP's powers, the Foundation used to resort to decapitating the victim in order to temporarily incapacitate them during the harvesting. Now they just empty their skulls to keep them from screaming.
* Not as horrifying or deadly as the other [=SCPs=], but [[http://scp-wiki.wikidot.com/scp-613 SCP-613]] ability to make contaminated organisms lose all color and become black and white over the course of a few days and leaving the carriers unable to perceive or remember what colors are, brought shivers to me. Luckily any healed former carriers can develop immunities to the disease.
* [[http://scp-wiki.wikidot.com/scp-204 SCP-204.]] 204 comes in two parts: 204-1 is a colony of nano-machines that follows around 204-2, protecting him/her from harm. 204-2 is a child aged from 4 to 14, with a history of being abused, who can control 204-1. When 204-2 turns fourteen, 204-1 finds a new child to protect, and, if the former 204-2 is mentally stable, the former 204-2 is given a Class-A amnesiac and put into a foster care program. That's not the HighOctaneNightmareFuel. The real HONF comes from an addendum that explains that due to 204-1 freaking out if there isn't another suitable child to imprint on if needed, the Foundation have a group of suitable candidates. However, if they really need candidates quickly, they can enlist some more candidates who don't fit the protocol- i.e., they are of a suitable age (preferably under ten), but they don't have a history of abuse. The Foundation will then '''turn them over to 'caretakers' which will consist of D-class personnel convicted of violent crimes, child abuse, and pedophilia'''. It also says that the procedure for hiring the 'caretakers' is the same one for finding people to perform Procedure 110-Montauk on SCP-231. Jesus Christ.
** Oh, and as an aside? SCP-204 will psychically manipulate whatever it's guarding into taking dangerous actions so it is forced protect what it is guarding, and thus allowed to feed. The SCP literally forces the child into danger so it can feed.
** And on top of that? Right now it's guarding a '''complete sociopath''' who is very quick to threaten people with the hungry, amoral nanomachines!
** And as if to top the whole thing off, 204 is ''ludicrously'' powerful. The initial capture required an ''Abrams tank'' and an '''AC-130'''. Yes... to capture this thing, you need not only one of the most powerful armored vehicles in the world, but also DeathFromAbove UpToEleven.
* [[http://scp-wiki.wikidot.com/scp-787 SCP-787]] is rather mundane (average scenes of grisly horror and cannibalism with some poltergeist activity), but the real chiller is '''"TO BE SORRY"''' endlessly repeating on the flight log.
* [[http://scp-wiki.wikidot.com/the-great-short-story-contest 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 [[UpToEleven kicker]]: The theme for February? '''[[AfterTheEnd Post-]][[TheEndOfTheWorldAsWeKnowIt SCPocalypse]].'''
* [[http://scp-wiki.wikidot.com/scp-764 SCP-764]]. Because puppets were not scary enough already. These will end up killing the user. How's that for a comedy routine?
* [[http://scp-wiki.wikidot.com/scp-800 SCP-800]] is an antique scroll painting that regularly changes to reflect current political relations or tensions in East Asia. It currently depicts two soldiers in combat, mirroring the tenuous state of relations between the North and South Koreas. The Foundation once performed a test to see if adding objects into the painting had any kind of effect; an expert in East Asian art added a quiver of arrows to one of the soldiers. Three days later, North Korea did...something that ended up purged from the records and stopping all further testing on SCP-800. The arrow metaphor gave me a [[EmptyQuiver pretty good guess]] [[NukeEm what happened]]...
** It gives a date of May 25th, 20██. Now, scrolling through The Other Wiki, I found [[http://en.wikipedia.org/wiki/2009_North_Korean_nuclear_test something that happened on May 25th]].
** Presumably, adding the arrows made the nuclear test occur. That's not the worst thing; there's mention that it once took the appearance of a Khmer stone carving. The description of said carving has been expunged. Predictable, considering [[http://en.wikipedia.org/wiki/Khmer_Rouge what happened...]]
** Almost all SCP [REDACTED] or [DATA EXPUNGED] marks are indicative of HighOctaneNightmareFuel or something else really gory. Most refer to something that the Foundation did, or something that an SCP did. Not the description of the Khmer carving–this was a non-fictional event carried out by real human beings. And the SCP Foundation expunged its data. [[HumansAreBastards Yeah...]]
* [[http://scp-wiki.wikidot.com/scp-823 SCP-823]]. A theme park that killed over 200 people in horrific ways (such as somebody in a mascot costume being filled with stuffing). Anybody sent in after that dies. So they can't find out what's going on, and that can't contain it because it's ''growing''.
** [[NothingIsScarier "Unable to determine context or content of above photograph."]]
** The last paragraph in the "civilian deaths" section. Someone was completely dismembered... and, at the very end, it's mentioned that he was still alive when they found him like this.
** The commander of the Mobile Task Force team was found dead from suicide. That's not the scary part. The cause of death was from [[EyeScream "forced sexual entry through left eye"]]! Think about that for a second.
** If you're savvy enough to realise some of the images are of a theme park that was supposed to open in Chernobyl, then it becomes...slightly less terrifying.
* [[http://scp-wiki.wikidot.com/scp-741 SCP-741]] is a sunken Russian submarine split into three pieces and guarded by the Foundation. The HighOctaneNightmareFuel? An attached interview with an American spy that said that the sub was carrying some kind of new weapon that not only made a bioweapons researcher sick, but that the Soviet couldn't safely control -- they sent the sub away to get rid of whatever it was.
* [[http://scp-wiki.wikidot.com/opportunity-knocks Opportunity Knocks]]. Apparently based on a recurring nightmare of the author's...
* During the experiments with SCP-914, they put in ''IWannaBeTheGuy''. Setting on Rough made up the games used for IWBTG, simple enough. 1:1 made Kaizo Mario World. Fine gave them ''Super'' I Wanna Be The Guy, which is undoubtedly near-impossible. Finally, Super Fine had all information denied by the O5's. This means that this... '''thing''' that resulted from putting IWBTG in SCP-914 has been formally denied existence of by the ''Foundation's directors''!
* [[http://scp-wiki.wikidot.com/wednesday-1 This story]], especially the ending. Watch me fly!
** [[NothingIsScarier The fact that you didn't list which SCP caused it is really freaking me out.]]
** With all of the parts written, the final ending seems to be something more akin to a CrowningMomentofHeartwarming.
* [[http://scp-wiki.wikidot.com/scp-734 SCP-734]]. Awww, it's a cute baby boy. And if you touch him your body starts to break down and flake away.
* [[http://scp-wiki.wikidot.com/scp-058 SCP-058]] resembles a ''bovine heart with tentacles and spikes''. It also talks, although whether that's a good or bad thing depends on how creepy you find poetic ranting.
* [[http://scp-wiki.wikidot.com/scp-290 SCP-290]] reads like a love letter to the BodyHorror sub-genre: it reconfigures your body in wild ways while keeping you alive. The Experiment Log Addendum includes the poor test subject's head "slowly embedding itself into his thigh, both eyes absent", and a strong implication that -- horribleness warning -- the restructuring of his internal organs had re-routed some of his waste through his chest cavity.
* 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.
* [[http://scp-wiki.wikidot.com/scp-775 SCP-775]] are ticks as big as nickels.
** "[[spoiler: Hosts will eventually be fully hollowed out, with only the outer layers of skin remaining]]." Thank you, SCP, because [[{{WhyDidItHaveToBeSnakes}} regular ticks weren't horrible enough.]]
* [[http://scp-wiki.wikidot.com/scp-370 SCP-370]] is an memetic hazard that spreads via sight, knowledge about said hazard, sight of the end result, etc. Don't read it if you plan on getting sleep.
** Not to mention that it's implied to be created by [[GodIsEvil God]].
** Furthermore, people infected with it rewrite the page to spread it. How do you know you haven't been infected yet?
* [[http://scp-wiki.wikidot.com/scp-781 SCP-781]] is a person who involuntarily manifests his own nightmares, and is killed by them an average of three times a week.
* [[http://scp-wiki.wikidot.com/scp-035 SCP-035]], a comedy mask that constantly secretes a corrrosive substance from its eyes and mouth. This calls for a glass containment since glass dissolves slower than everything else. People that see it want to put it on and when they do they are possessed by it as their body slowly decays, even past the point where (mechanically) they shouldn't move. The entity has complete knowledge on [[MindScrew human psychology]] and uses this along with [[AffablyEvil charm]] and telepathy to [[HannibalLecture convince ''anyone'' to do anything]]. [[ItGotWorse It gets worse]]. After a while, they decided not to give it any more hosts, realizing the potential this thing had. It starting driving people around the cell to suicide and depression. They coated the walls with an alloy that blocks telepathic suggestions, and it started decaying the walls with corrosive blood. Now, its cell is almost impossible to enter, due to the dangerous phenomenon within. [[BeyondTheImpossible It gets worse.]] The entity also shows interest in [[OhCrap 682]], whose regenerative abilities could counter the mask's corrosive decay, giving it a permanent host.
* [[{{God}} SCP-343.]] He's God, how can he be scary? If he's God, that means he is (however indirectly) responsible for the [=SCPs=]. Possibly including [[OmnicidalManiac SCP-682]].
** Now, now, in 343's defense, he/He denied having anything to do with 682, and in fact cannot see it. This gives a new level of terror. 682 vs. 343, and 682 would win.
*** 682 charged right through 343 without either of them noticing. Neither one can directly sense the other in any way.
** It's pretty clear that 343 isn't "God", just an incredibly powerful being. Plus, God [[http://www.scp-wiki.net/gdp2-second-language is not feeling like himself these days.]]
** Either way, he can't touch 682 and is still more than capable of messing you up something fierce. 343's exact identity is left reasonably open-ended, so the reader can draw their own conclusion.
* [[http://scp-wiki.wikidot.com/scp-966 SCP-966]]; an invisible humanoid ''thing'' that hunts by making you unable to sleep. Imagine it; you're in your house, at 2 AM and you are dead tired, but for some reason you just can't sleep. The night goes on and on, you keep moving uncomfortably in the bed, and nothing. Comes 6 AM and you have to get up to go to work. The whole day you are just shambling through the world like a zombie, trying desperately to at least have a little nap, but ''you simply can't get asleep''. When you're finally so tired you can't even move, a sharp pain comes from somewhere on your body and all you see ''is your flesh being ripped off with no clear reason as to why''.
** YOU SHOULD HAVE WARNED US ABOUT THE PICTURE. JESUS CHRIST.
** More squick than terrifying, but when someone took a picture of one of those creatures with SCP-978 (the Desire Camera), it showed a picture of two of them ''mating''. Just... try to imagine those things doing that... *shudder*
* Four words: [[http://scp-wiki.wikidot.com/scp-426 I am a toaster]]. God, reading my page is still scaring me.
** To elaborate, I am a toaster that makes people refer to me in the first person. Nobody's ''ever'' been able to refer to me in the third person, no matter what they do or don't know about me. Eventually, they completely forget who they are, and usually die when trying to emulate the functions of a toaster (one person died because she ingested so much bread that her stomach ''bursted''). [[http://scp-wiki.wikidot.com/that-goddamn-thing This short story]] also demonstrates my potential for creepy.
* [[http://scp-wiki.wikidot.com/scp-455 SCP-455]]. A ghost ship.
** It's more like an EldritchAbomination ship. For example: Weird temporal distortions, messed up interior dimensions, not really having any clue what goes in inside, things [[ItGotWorse getting worse]] for exploration teams, and so on and so forth.
** Thank you. I was having trouble putting into words ''exactly how messed up'' this thing ''is''.
* Dr. Bright. Aside what he did to his own brother, he is a god of FridgeHorror. Just look at [[http://scp-wiki.wikidot.com/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation 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.
** [[http://scp-wiki.wikidot.com/forum/t-115448/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation#post-934222 Word Of God]] says that the list is not in-universe. So, although Bright ''is'' an asshole, he's not an completely irresponsible asshole.
** But then again, half the time he ''is'' a monkey, so it kinda makes sense.
** Bright's own [[WhoWantsToLiveForever life]] is a FridgeHorror in and of itself.
* [[http://scp-wiki.wikidot.com/scp-363 SCP-363]], the centipedes that grow enormously in the dark. And not into giant centipedes, but into horrific tentacled monsters. To top it all off, [[spoiler:they have the apparent ability to infect people and [[BodyHorror transform them into more of them]]. One of these infectees are a mobile task force agent, who escaped and is possibly out loose into the world.]]
** Y'think that's bad? [[spoiler: The page says F. Tell is to be stopped at all costs. It does not actually make note of him being stopped. Which turns that "possibly" into a firm "definitely".]]
* [[http://scp-wiki.wikidot.com/scp-632 SCP-632]], a species of tiny, hermaphroditic, self-fertilizing spiders. Their eggs are light enough to float on almost non-existent breezes. When they land on warm skin, they hatch, burrow into your ''sweat glands'' and travel through your blood vessels to your brain. Then they burrow in ''THERE'' so they can feast. This causes a minor headache, which is alleviated by light tapping on the closest part of their head. As they continue, the headache gets worse, meaning the host has to hit their head harder. Eventually this leads to ''caving your own skull in''.
* [[http://scp-wiki.wikidot.com/scp-700 SCP 700]]. There was a hole here. It's gone. Now the hole's back, but the person who fell in is gone.
** [[spoiler:You really want scary? The goddamn face picture on the left MOVES, and it's only action is a quick half-second look directly at you.]]
* [[http://scp-wiki.wikidot.com/scp-096 SCP-096]] is a creature who is docile until you look at it's face at which point it will charge at you and kill you. The bad part about this is this works even with pictures and it will track you down no matter how far away you are. Also there have been pictures spread on the internet and the SCP Foundation is still in the process of removing them.
** To understand how horrific this is read [[http://scp-wiki.wikidot.com/incident-096-1-a Incident-096-1-a]] in which SCP-096 tracks down someone who saw it's face in a picture in which its body was only 7 pixels. So you can be looking at a picture and never notice it's there.
** Oh, and did we mention that when enraged, it's invincible? And that it's capable of bringing down an AWACS plane? And that it doesn't just kill its victims, it also [DATA EXPUNGED] them, leaving no trace of the body?
** There is one bit of good news: [[spoiler: -096 has been scheduled to be terminated.]] Though it took [[spoiler: letting the creature escape and wreak havoc on a highway, a small population center, and a military aircraft, ending with the execution of the scientist who arranged for the breach to happen]] to convince the [=05=] to act.
* You know you're dealing with some master writers when they can make ''cups'' ParanoiaFuel. [[http://scp-wiki.wikidot.com/scp-198 SCP-198]], a cup that can teleport and pretend to be other beverage containers. When you pick it up, it instantly bonds with your skin and cannot be removed, even by amputation. You rapidly become dehydrated unless you drink from the cup. What's in the cup? Human body fluids, like spit, sweat, bile, mucus, and...some less pleasant ones. Also, since you dehydrate so fast, your only hope is to chug everything in the cup constantly. I'd make a 2girls1cup joke here, but I doubt it would help.
* [[http://scp-wiki.wikidot.com/scp-182 SCP-182]]: A nice, cheerful guy who wants to be friends. Oh, and did we mention that he's deaf, mute, and horribly scarred, and he compensates for the first three by involuntarily riding shotgun on your senses when you get within ten meters, and if you stay around him there's a 97% chance you'll go insane? And he knows this. And he can't do a thing about it.
* [[http://scp-wiki.wikidot.com/scp-478 Well, how bout the Tooth Fairies?]]
* [[http://scp-wiki.wikidot.com/scp-600 SCP-600]]. The things it does with victims... Do Not Want.
** Not to mention the picture, which in a real-life context as a mugshot would represent in a detached manner a degenerate white trash sex offender and/or serial killer, while it screams, especially with its eyes, to this troper, "CompleteMonster with RAPE FACE!"
* [[http://scp-wiki.wikidot.com/scp-084 SCP-084]]. The static tower. It causes distortions of reality within its area of effect, trapping a small town within. They can't die, age, and have no need to sleep or eat. They also can't escape. One man was picked up four hundred meters from the city limits. He'd been traveling for ''six years''.
* [[http://scp-wiki.wikidot.com/scp-616 SCP-616]] is a prototype airplane. The emergency door opens on its own every 30 days, revealing what is essentially implied to be Hell. However, the worst thing you can do is let the door ''close'' before the manifestation is over...
** As scary as that entry is now, it was actually a lot worse when it was first written. [[http://replay.waybackmachine.org/20090316131454/http://scp-wiki.wikidot.com/scp-616 See for yourself.]] Among other things, it tells you exactly what was on the recording.
* [[http://scp-wiki.wikidot.com/scp-456 SCP-456]] are bedbugs. When they bite you, they produce narcotics in your brain, causing you to feel increasingly sleepy until you sleep constantly, causing you to die of malnutrition. They can't be distinguished from ordinary bedbugs, and you probably won't know they're 456 bedbugs until it's too late.
** Even worse, they exposed four D-class to the bedbugs. After expending three of them, they put the fourth one on a regimen of IV nutrients, blood transfusions, and narcotics antagonists. He's been asleep for a long time. The number of days is blanked out, but it's a triple digit number...
* [[http://www.scp-wiki.net/scp-686 SCP-686]] By itself, it's not scary, but once you think about the implications, you will freak out. 686 is just milk, except it contins an infection that causes mammary glands to devlop in mammals, even males. If milked regurlay, the diesase won't advance any further. If left unchecked, however, your ''entire torso will become an gigantic udder.'' Not only that, but because you have to eat all the time to keep your metabolism up, ''you'll become nothing more than a docile animal.'' Just imagine what a sick mind could do with that. On the other hand, you could consider it FetishFuel.
* [[http://scp-wiki.wikidot.com/scp-860 SCP-860]] seems fairly ordinary by SCP standards - a blue key that leads to a blue-misted forest with some unseen creature stalking you as you walk through it. The ''real'' chiller is the end of the last exploration log and that very last bit of audio.
* [[http://scp-wiki.wikidot.com/scp-624 SCP-624]] seems on the surface to be one of the more benign SCPs. It is an ordinary MP3 player which, if used, plays the users favorite music, covered by a more musically talented version of the user. But if someone with no musical preferences uses it, it plays the users soul. Meaning that you hear everything you have ever felt and heard and thought, including the bits you are ashamed of, right up to and including your own death.
** Death nothing. The examples provided in the main SCP page for 624 state the last track continues ''into the afterlife.'' Specifically, continuing ''as the soul is tortured in hell.'' This happens '''Twice.'''
* [[http://scp-wiki.wikidot.com/scp-750 SCP-750]] is a pair of contact lenses made by The Factory. When you put them on, it displays a variety of changes, like food becoming piles of limbs and gore, walls becoming coated in biofilm, and the skies becoming red and black. Victims who have the glasses on for too long usually get schizophrenia or PTSD. Real scary part? The lenses LET YOU SEE THINGS AS THEY REALLY ARE.
* Goddamn it, the whole ''website''. The titles are very mundane numbers and stuff, so...you never know if you're clicking on something funny, [[{{Squick}} squicky]], or an insanely [[HighOctaneNightmareFuel fucked-up]] EldritchAbomination that will keep you awake for ''days''. And the ''pictures''...oh, god, the pictures...
* According to [[http://scp-wiki.wikidot.com/document-recovered-from-the-marianas-trench 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....
* How about [[http://scp-wiki.wikidot.com/scp-528 SCP-528]]? They're little plastic containers containing silly putty that copies whatever image of a person is pressed onto it. Sounds harmless right? Wrong. Whatever happens to the picture happens to the person. The tests are horrific, the first one involving a D class having first his arm stretched unnaturally long, which is apparently painful and then torn off. The second subject is crushed into a ball and suffocates on his own flesh. The third one however is the worst of all. The putty is dipped in boiling water and the D class actually melts until he suffocates on his own nose.
* [[http://scp-wiki.wikidot.com/scp-736 SCP-736]]. It's [[CommandAndConquer Tiberium]], except that it ''feeds on your blood.''
* [[http://www.scp-wiki.net/scp-939 SCP 939]]. Read the whole page and all its included documents. [[spoiler:They are these ''things'' that attack people and breathe amnesiacs. Doesn't sound scary? Read the document, "Reproduction of SCP-939." The whole thing. The audio log is a blend of HighOctaneNightmareFuel, TearJerker, and just a bit of AdultFear. Those things are sentient and, when they're young, they ''are just like small human children''.]]
** The worst part? Putting them into 914 on "Fine" and "Very Fine" ''killed'' them–in essence, they're '''supposed''' to be dead.
* 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. Maybe it's just me, but I find that terrifying.
* [[http://scp-wiki.wikidot.com/scp-772 SCP-772]]. More BodyHorror, except this time with bugs the size of your thighs.
** Elaboration: They're wasps, MadeOfIron to an extent where bullets and even ''fire'' are useless, with a stinger longer than they are. When they sting you, they inject eggs under your skin, which is described as being 'excruciatingly painful'. Read the whole thing, if you can stomach it.
*** It's also implied that they're more likely to go after you the more afraid of them you are.
* [[http://scp-wiki.wikidot.com/scp-592 SCP-592]]. It's a history textbook. From an alternate timeline. If you read it, you're absolutely fine, as long as you read about something that happened before June 15th, 1956, when the timelines diverged. Anything past that and your mind is warped -- you start remembering things according to the alternate timeline's history, not reality. Reading an entry covering within 2 months from June 15th, you get a headache and can recover. 2 years, you'll have panic attacks and minor mental illness for the rest of your life. 10 years, psychosis and dementia. Anything past that and your perception of reality starts to break down completely.
** It gets worse. People who start remembering history differently due to this book can be ''physically modified'' to match the book's history -- gaining scars and losing limbs in wars that never happened, for example. Worse still, a significant number of the articles mention known SCP objects, suggesting the divergence point is [[spoiler: the founding -- or rather, lack thereof -- of the SCP Foundation.]] (The timeframe is actually spot on for this theory.)
** The Foundation is using a complex system of computers to analyze the book, due to nearly anyone even looking inside the book going absolutely stark raving mad. They are effectively getting the computers to "learn" that history and tell us it in the most vague terms possible. One of the final entries on the page suggests something far, far more sinister is at work:
--> ''The image contains two (2) ADULT PERSONS standing, one (1) HUMAN CHILD sitting on a CHAIR or STOOL, and SCP-███. With 100% certainty the PERSONS in the image should have FACIAL FEATURES. [[TheBlank With 100% certainty the PERSONS in the image do NOT have FACIAL FEATURES.]]''
* [[http://www.scp-wiki.net/scp-930 SCP-930]]. It's an uncharted island. The birds around it, 930-1 attack anyone who gets close. They don't kill, just cause minor wounds. They're not trying to hurt you, they're trying to get you away from the island. There's something much worse there...
* [[http://scp-wiki.wikidot.com/scp-716 SCP-716]]. On the surface, it doesn't seem too scary- just some kind of ghost train, but that's until you get to the part about a boxcar filled with dead horses, or a tanker filled with human bile. Plus there's the fact that if it comes near you ''you're compelled to kill yourself''. And if you're on board the train when it gets too fast, it's likely that you're sent to another planet to die.
* [[http://www.scp-wiki.net/scp-870 SCP-870]]. Ever drop something and can't find it again?
* '''[[http://www.scp-wiki.net/scp-1000 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...
** And later on, they leave us this message:
--> [[spoiler:we forgive you;]]
--> [[spoiler:given choice for now, not forever;]]
--> [[spoiler:let us back in]]
* [[http://scp-wiki.wikidot.com/scp-517 SCP-517]] I became paranoid after having seen one of the pictures move (having been a .gif), so I have a tendency to quickly copy and paste the link to a picture to check if it'll spaz out in any way. The picture with the glass is a .gif, so I didn't stick around long enough to see if it would move.
* Why are all old photos in black and white? Not because we didn't invent color photography until relatively recently. Because [[http://www.scp-wiki.net/skybluesky we didn't invent COLOR until recently.]]
** Although that could become NightmareRetardant when you remember that that was the premise of one of [[CalvinAndHobbes Calvin's father's]] LittleKnownFacts.
* [[http://scp-wiki.wikidot.com/scp-993 SCP-993.]] It's like CandleCove as done by a MonsterClown - except Candle Cove didn't [[BrownNote brainwash children]]. In one episode the clown just stares at you. [[NothingIsScarier For the entire episode.]] What makes it worse is at in that next episode you can tell who he's really staring at: [[spoiler:''The SCP Foundation''. '''''[[ItCanThink It can think.]]''''' It is a sentient, evil ''television program'' and it knows who's watching. Even it's ''archived copies'' are aware. It knows the Foundation is blocking it's broadcasts and ''[[VillainousBreakdown it's pissed]]''. It's copies are kept on the Foundation, so he could easily learn about a memetic hazard and ''get creative...''.]]
** It already knows about certain SCP's, and how to breach containment for them. For all we know, [[OhCrap it may have already found one]]
** One short story on the site makes Bobble even scarier with TheReveal that [[spoiler:Bobble isn't just a television program. It's an EldritchAbomination that existed since the dawn of humanity and has spent all that time encouraging violence in humans. Its first act was to teach them the secret of fire. "Bobble" is just its most recent idea.]] In the same story, Bobble also reveals that [[spoiler:he's perfectly capable of killing people in the real world even in containment.]]
** Of course, the fact that its second-most-recent episode is entitled "[[ClusterFBomb FUCK YOU! FUCK YOU! FUCK YOU!]]" and is basically 30 minutes of extremely angry shouting from Bobble makes things a bit funnier.
* [[http://www.scp-wiki.net/scp-611 The living toothpicks...]]
** To elaborate: They are a species of botflies. Botflies are insects that nest in human flesh, with their larva feeding off the person and eventually burrowing out. These particular flies can impersonate toothpicks, and lay their eggs in the gums, eating their way out. [[{{Squick}} And there's a picture.]]
* [[http://scp-wiki.wikidot.com/scp-1100 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 [[EverythingTryingToKillYou plants, wild animals livestock and even pets]]. [[spoiler: It's implied that [[GaiasVengeance the Earth itself]] is creating the substance.]]
* The [=SCPs=] that [[WouldHurtAChild specifically target children]] really creep me out. 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...
* [[http://www.scp-wiki.net/scp-136 SCP-136]] is a doll. When you look at it for too long, you get {{mind rape}}d (in a way heavily reminiscent of ''physical'' rape) by a naked, insane, blood-covered ghost thing that inexorably floats towards you, laughing, before shoving its face right ups to yours and screaming before disappearing. It usually takes the form of a woman with an obscenely large mouth and oversized breasts. And now we're finding out that it can kill people...
* Dr. Wondertainment, and the fact that his/their SCPs are ''made for children''.
* [[http://scp-wiki.wikidot.com/scp-953 SCP-953]] is pretty freaking scary. The interview with one of the Foundation agents who encountered it is... yeesh.
* [[http://scp-wiki.wikidot.com/scp-089 SCP-089]] is a golden idol with a cavity in its chest that either causes or can prevent horrifying disasters; either way, they will only abate if Protocol M8 is fulfilled. What is Protocol M8? The statue names two people: SCP-089-A and 089-B. The foundation will send out a taskforce to convince 089-B to complete Protocol M8 out of her own free volition. Then comes the WhamLine. [[spoiler: "For each locution event, SCP-089-A is a healthy, unblemished human infant or child between eight months and six years of age, and SCP-089-B is that child’s natural mother. In all documented cases, at the time of the locution event SCP-089-B is alive, healthy and experiences a strong bond of trust and affection with SCP-089-A. Following SCP-089-B’s placement of SCP-089-A in the cavity and the ignition of the inflammable materials, SCP-089-A will burn and be destroyed over a period of two to five hours."]]
** Worse still, they haven't yet found someone to carry out Protocol M8 for the most recent prophecy, which is naturally hidden behind a "DATA EXPUNGED." In the past, when it took 49 days to find someone willing to carry out the protocol the casualties were in the thousands. (It's implied they could have been much worse.) By the date shown on the page it could be up to nearly '''12 years''' since the most recent prophecy. [[hottip:*:Which could be anything, including climate change, the war on terror, the global economic crisis, the Haiti earthquake, or the Japanese tsunami.]]
* [[http://scp-wiki.wikidot.com/scp-1042 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... [[spoiler: 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 minor accidents. Wait, did I say minor ? Sometimes they cause LETHAL accidents. AND THEY KNOW THEY'RE BEING WATCHED BY THE SCP AGENTS.]]
* And for Nightmare Fuel it is really hard to beat...[[http://www.scp-wiki.net/ethics-committee-orientation 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.
* And the [[http://scp-wiki.wikidot.com/and-then-i-died2 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.
* [[http://www.scp-wiki.net/scp-435 SCP-435]] is a meteorite to which a ''[[AlienGeometries very]]'' strange entity that is seemingly immaterial, yet does horrible things to solids that it touches, is bound. Also, if the meteorite isn't illuminated at all times, it can move around. We aren't told what happens when it intersects with landmasses or water, but apparently when it happened during its retrieval it had to be passed off as ''a nuclear test misfiring''. Apparently [[spoiler:it's an EldritchAbomination [[SealedEvilInACan sealed]] to the meteor who cannot see in the light, so he cannot find his way back unless it's dark, and the entity is its ''shadow'' on the material universe. Oh, and if it it goes dark for more than 90 seconds, it could [[ApocalypseHow cause an XK-class scenario]], and the backup plan is dumping the rock in another universe, which might actually break the seal.]]
* [[http://scp-wiki.wikidot.com/scp-710 SCP-710]]. Entering this city will cause you to ''slowly fade from existence.'' And it's totally irreversible once the symptoms manifest, to boot!
* [[http://www.scp-wiki.net/scp-515 SCP-515]] is a young man who causes celestial objects to move towards earth whenever he moves any part of his body. The good part is that he is asleep and is easily constrained, the bad part is that he sleepwalks and his very breathing counts as movement. The sheer impact SCP-515 has on this troper is that not only is it causing a potentially world-ending scenario, it isn't even trying to do so. In addition the feeling of inevitability really nags away on you.
* [[http://scp-wiki.wikidot.com/scp-895 SCP-895]] is not really all that scary to read about. A little chilling, but the really scary thing [[spoiler: is that live video feed. Watch it. [[SchmuckBait See what happens.]]]]
* 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 it's 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.
* [[http://scp-wiki.wikidot.com/scp-017 SCP-017]] is a shadowy figure roughly the size of a young child. Unlike some other dangerous SCP objects, it generally remains stationary and does nothing to actively harm anyone... until a shadow is cast upon it. When that happens, it will immediately leap at and engulf the object or person, then return to normal size as if they were never there to begin with. And all of the Foundation's attempts to discover what, if ''anything'' is within those shadows or where the victims go has been unsuccessful.
* [[http://www.scp-wiki.net/scp-020 SCP-020]] is a germaphobe's nightmare-- a mold that is invisible to humans unless videotaped or photographed, can grow all over your house and ''even on your body'', and changes your personality to make you more sociable so it can spread to all your friends.

''Please add new examples to the bottom of the page.''

* 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 assault 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.
** Nah, I think the crowning piece would be that little bit on that page about Tvtropes: "Human Resources is encouraged to draw upon personnel drawn from [[http://scp-wiki.wikidot.com/scp-4445-j SCP-4445-j]] in first-stage recruitment for personnel, D-Class or otherwise." Hello, future D-class personnel.
** No. The worst one are the ones that say something like "Due to the nature of this SCP, it cannot be contained."
* [[http://scp-wiki.wikidot.com/scp-583 SCP-583.]] Good luck watching SesameStreet again.
** I dunno, I think there'd be an upside to it. For example, I'd enjoy Fox News, Reality TV, etc. a lot more once I'd watched that tape.
* [[http://scp-wiki.wikidot.com/scp-280 SCP-280.]] It attacks people and rips them to shreds... for ''no reason.''
* [[http://scp-wiki.wikidot.com/scp-173 SCP 173]], the statue that tries to kill you if you break eye contact with it.
** Enlarge that page's picture to get a better idea. Enter the jibblies.
** 173 appears to be ''the only thing 682 is afraid of'', as when it was locked inside 173's chamber its first response was to huddle in the corner farthest from 173 and stare at it without blinking for several hours. When snipers popped 682's eyes from afar, it responded by growing bullet-proof eyes all over its body so that it could keep 173 from getting close to it.
** For extra nightmares, think on this: As long as you look at it, it's a harmless statue with entirely curved edges, no claws or anything, made of [[strike:papier mache and therefore probably very light]] concrete and rebar, so it shouldn't be able to move. So... what is it when you're not looking at it?
** Also: [[http://scp-wiki.wikidot.com/revised-entry this short story.]] What would happen if said statue replicated. Exponentially.
** Said entry describes 150 SCP-173s attacking and ripping apart ''SCP-682. The fucking indestructible lizard.''
** [[http://www.youtube.com/watch?v=UBLIAasOfxk This video]]. The statue in action.
** Seriously, [[BrainBleach its appearance is what makes it terrifying]].
** [[http://scp-wiki.wikidot.com/scp-232 SCP-232]] falls into a similar vein. It's a statue of a Sumerian goddess that will cut you up if you allow any shadows into its constantly-lit containment area.
** Also: [[http://scp-wiki.wikidot.com/scp-978-extended-test-logs When SCP-173's picture was taken with SCP-978,]] there was no change[[hottip:*:Pictures taken with SCP-978 show what the picture's subject wants to be doing at the time of the picture]]. Think about it. [[spoiler: SCP-173 ''is exactly where it wants to be''.]]
** Isn't being where it is now significantly better than the alternative? The Foundation can at least try to keep it contained while it's where it is.
** Or it just might not be sentient. Which may be worse, as that means it does what it does for no reason at all.
** Even non-sapient creatures like animals tend to show some kind of change when photographed with SCP-978. The most horrifying possibility of all is that SCP-173 is either not alive, or a living being that lacks any form of consciousness or will whatsoever, ''yet continues to kill!''
** Tropers, you seem to have forgotten about [[http://img822.imageshack.us/img822/4066/tblink.jpg this]] comic. NothingIsScarier until it's smiling on your face.
** They've tried [[WhatAnIdiot duplicating]] SCP-173 with SCP-038 (a tree that can copy anything short of two hundred pounds). The good news? It stopped short of two hundred pounds, so only the head, right arm and upper torso was copied, and it moves so slowly that they didn't notice it during testing. The bad news? It ''didn't stop moving'' when it was observed. This thing is supposed to be a perfect copy of the original; how could we stop it if it just decided to ignore its one supposed weakness?
** Perhaps SCP-173 is just [[spoiler: putting up an act of being able to move only when not observed. The clone could have either not come to the conclusion the original one did, or just attacked because it felt like that was its last resort.]] What's horrifying about this is the implication that SCP-173 could [[spoiler: attack anyone, at anytime, but it's just '''messing with you.''']]
** And worse, it sounds, suspiciously like [[{{Doctor Who}}another creature that moves when you don't look at it that is a statue...]]
** In the game "Containment Breach", you have to run away from it, among other SCPs. And if you encounter it, and you close a door in between SCP-173 and yourself? [[spoiler: It ''opens the fucking door'' and resumes chasing the player. There is literally ''no way'' to stop it]].
* [[http://scp-wiki.wikidot.com/scp-106 SCP-106]] "The Old Man". An entity resembling a rotting old man. It causes severe corrosion and decay of whatever it touches. It drags its victims into its pocket dimension (which it seems to have complete metaphysical control over) and slowly tortures them for hours or days, before ejecting their mutilated bodies back into this world. Take a look at the page [[http://scp-wiki.wikidot.com/scp-106 pictures]]. As if that wasn't enough, it's completely indestructible and almost impossible to successfully contain.
** Finally, someone agrees with me. Not even making jokes about it and [[http://scp-wiki.wikidot.com/scp-033 SCP-033]] helps with the horror.
** ''"SCP-106 appears to prefer human prey items in the 10-25-year-old age bracket."'' Aside from how horrifying ''that'' is, I don't even ''want'' to know how the Foundation discovered this.
** The procedure for its recapture is, if possible, more terrifying than it is. Namely, taking a human in said age bracket and injuring them by breaking a bone or cutting a tendon, placing them in a cell, and broadcasting their cries to lure in SCP-106. If SCP-106 isn't taking the bait, ''additional damage'' is inflicted. If it still isn't working, more "prey" objects are brought in. ''Hoe-shit.''
* [=SCPs=] [[http://scp-wiki.wikidot.com/scp-076 076-2]] and [[http://scp-wiki.wikidot.com/scp-682 682]]. Both are indestructible, very sharp killing machines. Sure, you can put them down for now, but they'll just come right back again in a few minutes.
** SCP-076 has a long description on its page about how in "the worst breach to date", its containment site was forced to set off a nuke, killing everyone and incinerating the location... '''[[NighInvulnerable and failing to kill the SCP]]'''.
** SCP 682 is described as a reptilian monster able to mutate and regenerate body parts, with hyperintelligence, and [[OmnicidalManiac a hate of all forms of life]], and the ability to adapt to anything. It's still capable of talking (usually in the form of obscenities and threats) with as much as 80% of its body mass destroyed, and needs to be kept in an acid bath so as to constantly keep it weakened. What makes it worse is the fact that they have to experiment with other [=SCPs=] to try and find away to permanently destroy it. The most frightening thing? It usually fails, and then it becomes immune to whatever they tried.
** How about the interaction between 682 and 826? [[http://scp-wiki.wikidot.com/scp-826 862]] is a pair of pewter dragon statues that transform the room it's in into the setting of any book placed between them. If the people fail to escape the room, they will lose all memories of their past lives, and the story will rewrite itself to incorporate them. Realizing this, the SCP wrote a 12 page short story called "The Generally Nice, Friendly Thing That Can And Will Kill SCP-682 Permanently if it So Much As Spots That Damn Lizard", that was just a description of a plain green field, and a large monster whose sole descriptive quality was the stated ability of permanently killing 682. So, they put 682 in there, and in a matter of minutes, the plain green field turned into a scorched crater-filled wasteland, and the 12 page short story had become a [[strike:1,000+]] 209 page epic called "The Generally Nice, Friendly Thing That Tried To Kill SCP-682 Permanently But Failed" describing the epic battles between this monster and an innocent creature whose very existence was based around its ability to destroy 682. And 682 won. [[TearJerker Poor thing]].
** Yes, that's right. They wrote a story about something that ''specifically could kill 682'', and 682 ''killed it''. That's how unkillable the bloody thing is.
*** What makes it worse is [[http://scp-wiki.wikidot.com/scp-343 SCP-343]] will not get near 682 and calls it an abomination.
*** [[WordOfGod Dr Gears]], 682 creator, says that, in his view, 682 wants to kill everything because, through his eyes, life on this reality is so utterly ''wrong, disgusting and frightening'' to him that his only response is to destroy everything. It makes you wonder just how his homeplace looks like...
*** Sounds to me like a ''VisualNovel/SayaNoUta'' crossover waiting to happen. The human staff would like her fake form, 682 would like her real one, and until she destroys the planet everyone wins!
*** And SCP-053 ''likes'' the thing! It even seemed to like her back, actively trying ''not'' to scare her when they first made contact and even letting her draw on it with her crayons. Although SCP-053 looks and acts like a three year old girl, everyone over the age of three has an irresistible desire to kill her after ten minutes of exposure, and everyone who tries dies painfully. Perhaps SCP-682 feels the same way about humans as humans do about SCP-053. In which case, one wonders where 053 ''really'' came from...
* [[http://scp-wiki.wikidot.com/scp-689 SCP-689]], which will not only kill you if you break eye contact with it, it will teleport to you, and anybody who sees it now will also be in danger of death.
* 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 SchmuckBait, with the full knowledge that they'll ignore their orders and do something stupid... just so that the scientists will see what happens.
* [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] is a clockwork... thing that grows by absorbing all nearby metal objects and can brainwash anyone nearby into "feeding" it. [[http://scp-wiki.wikidot.com/scp-271 SCP-271]] is an engraved coin, whose inscription spreads to nearby objects and turns them into an indestructible metal with unknown properties. Accidental tests on living organisms suggest that both being absorbed by the machine and being converted by the coin are excruciatingly painful. There is an obvious reason these things are not to be allowed in the same room. The Church of the Broken God wants to try it out.
* [[http://scp-wiki.wikidot.com/scp-002 SCP-002]] is a ball of flesh with a door in it. Through the door is a modest apartment, complete with furniture made out of the body parts of the people it's killed.
* The old [[http://scp-wiki.wikidot.com/scp-112-arc SCP-112]] is an ArtifactOfDoom activated in the presence of any non-virgin or non-castrated person. And it has been stolen by radical Muslim terrorists. Get the idea?
* [[http://scp-wiki.wikidot.com/scp-415 SCP-415]], The Harvested Man. ExactlyWhatItSaysOnTheTin.
* [[http://scp-wiki.wikidot.com/scp-231 SCP-231-07]], a girl of undefined age who was impregnated with some kind of CosmicHorror by a Satanic sex cult. The only way to keep it from being born is by putting her through "Procedure 110-Montauk" every twenty-four hours, which is described as involving "brutally (DATA EXPUNGED)". Since it can only be carried out by convicted sex offenders among Class D Personnel, and is being supervised by employees who have passed a psychological examination in which "mild sociopathic tendencies and marked sexual deviancy are not to be considered automatic fail conditions" (an early warning and implication of who carries this out) it's [[strike:pretty obvious what it is]] [[WordOfGod 10 times worse than whatever you think it is.]]
** Here's one bit of extreme Nightmare Fuel relating to SCP-231: Some of the staff who were involved in the project have taken amnesiacs to forget it, and false memories have been implanted. Which means that ''you'' could have been on the project and not even remember it.
** Oh, and they started using amnesia-inducing drugs on 231 herself; the sum total of 110-Montauk was starting to induce a form of shell shock in the victim. As a constant level of agony and terror needs to be inflicted to supress the EldritchAbomination, they started wiping her mind of her knowledge of Montauk. Eventually it was determined that a weekly dosing cycle was most efficient, as the 3rd to 4th time is the most mentally devastating; the first time is horrible, the second time establishes a pattern, and the third confirms that [[DespairEventHorizon this is what the rest of your life is going to be like.]]
** The article contains an addendum added by one of the heads of the SCP foundation specifically stating (presumably to set straight employees having second thoughts about all this) that while "Procedure 110-Montauk" is quite possibly the most horrifyingly evil thing the SCP foundation has ever been involved in, failure to carry it out will result in the EndOfTheWorldAsWeKnowIt, judging by the death tolls that ensued when SCP-231-01 through SCP-231-06 gave birth. Sweet dreams.
** The specific age of SCP-231 is not specified, only a minimum and maximum, both of which are censored in the article. But the minimum is a single-digit number.
** And to make matters worse, it was originally just a censored two-digit number, but after a troper breathed a sigh of relief that at least 231-7 was not a child, the Foundation saw it and changed it, [[TemptingFate and replied to that post with "this is your fault,]] [[NiceJobBreakingItHero you made this happen".]]
** In such fine print that you may have to View Source to find it: [[spoiler:"Don't believe it when they say they're trying to save her. Why would they bother? They've got exactly what they want exactly where they want it."]]
** They're going to have to come up with ''something,'' though, because even barring any changes in her situation eventually she's going to die of natural causes, and the death of the previous six 231 hosts released their whatever-it-is. Since it wouldn't really make her situation much worse than it already is, putting her in something like the other SCP which is an iron maiden which prevents the victim aging or dying could delay the problem, but she'd still age while she was outside it for the Procedure, so it still wouldn't work indefinitely. Not to mention her [Data Expunged] may interpret that as an attempt to kill her and figure it was time to do its thing. And being fed via IV doesn't exactly prolong life, so they probably have less time than the average lifespan. Also, think about this; does she know what the thing she's carrying is, and would it make her situation worse or better if she did? If she did find out, either she may think "oh well, it'll prevent something even worse happening" and her distress level will be lowered slightly, which, since the distress level appears to be the important part of the Procedure, will be a problem, or she'll want to release the thing for revenge purposes. Pity the portal into a world already undergoing zombie apocalypse is no longer open, as they could have just shoved her through there - that world is already ending, and she'd no longer be the Foundation's problem. 231's situation, to me, is just plain {{Squick}}. The Nightmare Fuel aspect comes into play with the fact that they're keeping this thing under control using either the minimum safe or the only way to do so, ''they don't have a backup plan, and since the previous six hosts are all dead they don't have a way to safely test any plans they do come up with.''
** I have a WMG over on the WMG page to explain why they don't have a backup plan and why she "stays perpetually young".
** Alternately, imagine being part of the support staff for the 231 containment site. Knowing what you're ordering done to the girl, watching it every day, obtaining supplies and materials to enable it, terminating anyone who tries to stop it. There's a reason why so many people associated with this thing commit suicide.
* One of the most disturbing things about the SCP series (for some) 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.
* Even the [[http://scp-wiki.wikidot.com/scp-series#toc12 joke SCPs]] are creepy. Take [[http://scp-wiki.wikidot.com/scp-000-j SCP-000-j]], for example. It's a catalogue of every SCP item, which anybody can apparently order through a simple phone call as if they were everyday items. When one of the testers did call and order one of them (a safe-level item), it disappeared from its storage and mysteriously got delivered to his office, and the amount he would have paid for it vanished from his next paycheck. Now imagine somebody finding this catalogue and ordering one of the Keter-class items...
** Imagine them ordering 682?
* 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.
* The [[http://scp-wiki.wikidot.com/decomm:scp-316-d termination log of SCP-316-D]] is absolutely horrific. Even though he seems to be one of those Gary Stus that pretty much psychically forces you to like him, Surveillance Log x316███ was just gruesome. Also: The thought that he could wake up on a space probe en route to the sun is what most everybody's worst nightmare is made of.
** Given the nauseating levels of Gary Stu-ism given to SCP-316-D, I would argue its death was not nearly nightmarish enough. That said, the only reason the entry remains open is to demonstrate precisely the sort of puerile drivel that should never be added to the site in the first place.
* SCP-001 is generally reserved for the largest and most brickshittingly terrifying SCP concepts, so much so that the users of the site would rather not ruin the mystery by having a single canon SCP-001.
** The [[http://scp-wiki.wikidot.com/scp-001 SCP-001 proposal page itself]]. When you scroll down to see why "SCROLLING DOWN WITHOUT PROPER INNOCULATION WILL RESULT IN IMMEDIATE CARDIAC ARREST FOLLOWED BY DEATH," you will shit bricks. What makes it worse is that the image is designed to kill you. Now if that were an SCP, and it could spread...
** It's not supposed to be scary. The idea is that the patterns in the image are so illogical and confusing that, if viewed without safety measures, will cause the brain to 'crash', so to speak. This is not the first time such a concept has been explored.
** If you're curious that's a randomly generated image from the [[http://electricsheep.org/ electric sheep screensaver]]
** One of the possible SCP-001s. Completely harmless by itself. Its just [[http://scp-wiki.wikidot.com/jonathan-ball-s-proposal a sheaf of stapled papers containing detailed reports of the SCP items]]... except that every time you look at the report, the report is on a new SCP item, which then appears somewhere in the world. Let the sheer terror of that concept work its way into your brain.
** One of the other possible SCP-001s is [[http://scp-wiki.wikidot.com/dr-clef-s-proposal a huge humanoid figure standing in front of what is more or less the gate of Eden]]. Getting within 1 kilometer of it will get you not only killed, but wiped from existence. If it ever goes active, TheEndOfTheWorldAsWeKnowIt will ensue. Making matters worse is that the page includes a transmission from TwentyMinutesIntoTheFuture about SCP-001 waking up and bringing about said apocalypse. Mega-gulp.
** שמע ישראל יהוה אלהינו יהוה אחד [[spoiler: In case you were wondering, that's the most important prayer in Judaism. It's supposed to be your last words.]] Translated: [[http://en.wikipedia.org/wiki/Shema_Yisrael "Hear, O Israel: YHWH is our God, YHWH alone."]]
** My favourite concept for SCP-001: [[spoiler: [[Wiki/SCPFoundation a massive worldwise organisation that acts like a sociopathic MIB agency]].]]
** Another recent possible SCP-001: a large onyx gemstone with an infinitely fine fractal gold filigree, apparently serving as a lock for an unknown object. Doesn't really seem scary, right? [[spoiler:It turns out that the minute variations in the cosmic background radiation has ''the exact same pattern'' as this onyx lock. It's implied that our universe is contained in a similar object, and possibly the artifact in question. The Foundation is currently trying to [[ApocalypseHow open and/or destroy it.]]]]
** Bright's proposal for 001: [[http://www.scp-wiki.net/scp-001-o5 The Factory.]] Just...read it.
** [[http://scp-wiki.wikidot.com/dr-manns-proposal Dr. Mann's proposal]]. The SCP itself is very simple, just a circular gravel path. Travel clockwise, and you move normally. Travel counter-clockwise, however, and the path appears to go continuously uphill. [[MindScrew Even if you go all the way around to the start.]] The real horror comes when one reads the attached document from one of the founding Overseers. [[spoiler: Analyzing the Gravel Path led to the initial founders of the Foundation to the initial understanding of bending reality that allowed them to start manufacturing SCP objects. And the Foundation never "found" ''any'' SCP. They ''made'' them. ''All of them.'' -231, -051, -616, -682, all of them ''were created by the Foundation.'']] And the scariest part? [[spoiler: SCP objects are no longer being manufactured. They're just ''appearing'' in containment, with no indication of where they came from, and the Foundation has reached the point of no return.]]
** [[http://scp-wiki.wikidot.com/sandrewswann-s-proposal S Andrew Swan's proposal]] is a masterpiece of MetaFiction ParanoiaFuel. The details are so confidential that even the ''description'' has been expunged and the directives state there is no way of containing it without risking a ''ZX Reality Failure event'' (the destruction of the observable universe). No-one except the O5s is allowed to know anything about it at ALL. But there is a hidden message on the page from a researcher who worked on it and managed to escape the purge detailing it: [[spoiler:The reason the SCP Foundation discourages attempt at cross-referencing [=SCPs=] and looking for patterns in their seemingly random nature is that once, ''they did'' try to develop a Grand Unified Theory of [=SCPs=] and they discovered that reality is constantly shifting, things appearing and disappearing as if they'd never been, even whole sections of the Foundation's history changing. Eventually one of the researchers discovered the pattern- the shifting development of reality "toward narrative coherence, toward a plot..." And they discoverered the truth.]]
--->[[spoiler:But we found out there is a God, and it is SCP-001.]]

** Oh, and there's more: if you enter the encryption key identifying you as an O5 member with full authorisation of the O5 council, you can read Containment Protocol ZK-001-Alpha, their final sanction against SCP-001 to be used only in the most dire of emergencies. [[spoiler:They will virally insert a series of memetic attack agents into the SCP database itself that will [[TheFourthWallWillNotProtectYou infect members of SCP-001 and induce a state of calmness and well-being, followed by catatonia and finally a quiet death]]. [[ParanoiaFuel That's right, they've prepared a weapon to kill YOU as you browse the database]].]]
* The last line in Baba Yaga's entry was far, far more disturbing to [[{{Tropers/Whitewings}} me]] than poor 231-7's treatment. At least the higher-ups know that what they're doing to her is horrible, and want to find a way to help her. Quote: "While SCP-352 prefers any type of human flesh over any other type of meat, it appears to have a special propensity for children between 0 and 2 years of age. After observation of highly elevated levels of co-operation and a reduced tendency to attack staff while consuming flesh of this type, a possible alteration in the current diet is being considered."
** [[spoiler: No, they ''don't'' want to save 231; in very fine print after the end of Addendum 231-B, you can read: "Don't believe it when they say they're trying to save her. Why would they bother? They've got exactly what they want exactly where they want it."]]
** What, [[http://scp-wiki.wikidot.com/scp-352 this]] Baba Yaga? The Foundation just wants to make her more manageable by [[MoralEventHorizon feeding her toddlers]]. This is less horrifying when you realize that there's an SCP that turns animal flesh into human flesh, and, by logic, baby animal flesh into baby human flesh, but still. Don't tell anybody, they'll probably make an addendum rejecting it.
* [[http://scp-wiki.wikidot.com/scp-507 The guy who randomly teleports to alternate dimensions]], including one that apparently had the Joker who was right in front of him when he turned the flashlight on. "Back so soon?" The poor lad's reaction was probably the same as yours would be. Not to mention "...the spiders...".
** The interview log when another version of that teleporter shows up from an alternate dimension is terrifying. Basically they refuse to elaborate on which one is from the "real" dimension, to keep the other guy safe. At the end, one reveals that "In his reality, Lincoln was killed while sleeping by his then vice-president, instead of by General Lee." The interviewer responds "In our world, Booth assassinated Lincoln." The end of the article just states that "Subsequent testing revealed that SCP-507s abilities have no biological basing, and that severed pieces will still “shift” along with the main body."
** During one of his trips to another reality, 507 arrived in what seemed to be the facility, only in a state of disuse with corpses covered in a strange, breathing mold. Further exploration revealed that possibly ''the entire world'' was covered in the stuff. Upon further inspection of a mold sample 507 brought back, it was found to be very similar to both [[http://en.wikipedia.org/wiki/Cordyceps Cordyceps Fungi]] (some varieties of which basically brain-wash their hosts) and a fungus produced by - wait for it - [[http://scp-wiki.wikidot.com/scp-407 SCP 407]]. The Foundation consequently restricted experimentation with 407, and all known copies were terminated by "Serpent's Hand," but no one is certain if more copies may be found elsewhere.
* [[http://scp-wiki.wikidot.com/scp-294 SCP-294]] is a coffee machine that can dispense just about any kind of liquid. If you value your appetite, do not use "joe" as a synonym for "coffee" when inputting what drink you want, especially if your name is Joe.
** Said machine can dispense "My Favourite Drink", which is tailored to the individual's tastebuds, and "The Best Drink Ever", which causes the drinker to become depressive and commit suicide because "everything else is just a letdown now." For more straightforward ways of killing you, it will happily dispense any kind of acid. There's a ''reason'' why they have two security guards stationed there with orders to shoot anyone who is trying to order anything other than normal drinks for research.
** On the other hand, it also turned out "[[CrowningMomentOfHeartwarming Something Cassie will like]]," a [[HitchhikersGuideToTheGalaxy Pan-Galactic]] GargleBlaster, and a "cup of relevant medical knowledge."
** When asked for something that could kill SCP-682, the liquid was so intense it vaporized the entire site SCP-294 was in, apart from a small patch surrounding the machine. Given cases with other SCPs like this, whether it would've worked is anyone's guess.
* Speaking of disturbing food dispensers, [[http://scp-wiki.wikidot.com/scp-261 SCP-261]] is a vending machine that dispenses snack foods that might be normal, strange or bizarre. As [=SCPs=] go, it's actually pretty fun and not too scary. The disturbing part comes as you slowly read more and more stories about what comes out of the vending machine. The first time living food is dispensed, most researchers refuse to eat it and are as distressed by the idea as most people would be. But as more and more living food items are dispensed from the vending machine, researchers get more and more casual about it, until reports of the living, potentially thinking beings only describe their flavor. As if cramming the recently dead bodies of various cute little alien critters popping out of the machine is the normal and obvious thing to do.
** Another fun result from SCP-261 is "TASTE ME", an obvious reference to Alice's Adventures in Wonderland. It's funny, right until the part when the test subject eats it, goes into convulsions, and dies due to brain expansion. "Analysis of the cake showed large amounts of human growth hormone as well as several unidentified chemicals." Gee, thanks for ruining that book for me.
** Something really horrifying are the products dispensed labeled FOOD and DRINK. People who ate the FOOD became emotionless and dull-witted, while people who drank the DRINK became more and more subservient. Doesn't sound so bad by itself, [[FridgeHorror but think about]] where they might have came from, and what those products are used for there...
** And then there's the can of "Prangles." Once you pop, you can't stop. '''''Ever'''''.
** [[NightmareRetardant It also produced]] [[http://tentaclegrape.com/ Tentacle Grape]].
* [[http://scp-wiki.wikidot.com/scp-835 SCP-835]] was a collaboration between two authors: one of them was the guy who wrote the infamous SCP-231. The other wrote SCP-682. Their goal was to create the ultimate in squicky [=SCPs=]. Some would say they succeeded. For the full impact, read the article first, then the "uncensored" version, then the "uncensored" version of the exploration log.
** SCP-835 also serves as a bit of {{Fridge Brilliance}} [[HighOctaneNightmareFuel Nightmare Fuel]] for the entire SCP series. Now you know what kind of disgusting, freaky things are behind all those (DATA EXPUNGED) boxes, and they're exactly as bad as you'd think. "Now we can be together, just like he wants..."
** That adds sort of a ghoulish edge to several joke [=SCPs=] where [DATA EXPUNGED] was used for laughs.
** And then someone went and added a picture for 835. [[BrainBleach Cripes.]]
* The former [[http://scp-wiki.wikidot.com/scp-995 SCP-995]], an object that is too mentally scarring for many to describe. At best, it's been described as an "Infinite Devil Machine." It's required to be kept in a blessed lead container full of also-blessed holy water, which turns black and darkens whatever room its in. Recorded images of it breaking out of its container show tendrils poking out of its container. Unfortunately it's been deleted due to negative ratings and changed to a device which drives people insane as it touches an electric conductor. Eventually it was deleted altogether, although the original article can still be found [[http://replay.waybackmachine.org/20090317090832/http://scp-wiki.wikidot.com/scp-995 here.]]
* [[http://scp-wiki.wikidot.com/scp-217 SCP-217]] is a virus that turns people into machines. It can affect any animal, replaces organs and such with mechanical parts, and the affected creature becomes repetitive and locked in a set pattern of behaviour. Scared now? Oh and did I also mention that the Church of the Broken God wants to bring it into contact with [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] and [[http://scp-wiki.wikidot.com/scp-271 SCP-271]]?
* The worst one was [[http://scp-wiki.wikidot.com/scp-055 SCP-055]]. Which was also the coolest. Imagine seeing something, and not being able to describe it. It basically makes you forget anything related to it, being reduced to what it DOESN'T look like. [[http://scp-wiki.wikidot.com/incident-report-i-028-f This doesn't help either]]. An area that makes people gain immediate knowledge of a random subject. A man enters the area, goes into a fit, and afterwards forgets he was even in the area. Locked the memory out of sheer horror? Amnesia?
* Someone [[http://scp-wiki.wikidot.com/a-man-at-the-top-of-his-profession 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!
** It's no longer canon.
** [[OrwellianRetcon Of course it's no longer canon.]]
* [[http://scp-wiki.wikidot.com/scp-590 SCP-590]] is (objectively) nothing compared to most of these, but the fact that they purposely destroyed his mind, reducing him to the functional level of a three-year-old -- and for no reason other than to make him more controllable -- chills me to the bone. Worse than that is reading the experimental logs of SCP-978, a camera that shows the photographed subject doing what it desires to be doing rather than what it actually is doing. 590's picture is absolutely heartbreaking and one of the most chilling things she's read on the whole site.
* [[http://scp-wiki.wikidot.com/scp-093 SCP-093]] is my favorite. Read the whole thing, including the test reports, in order, and then read the last link on the page. It sent shivers down my spine; the reports themselves are creepy and unsettling, but the final report is just chilling.
--> [[spoiler:there was no war it was him him him him him IT. IT! it came from between the folds of time and space and worlds and light and dark something that is but should not be slipped in and called out to them as their god and they believed it and they tasted it and touched it and layed with it and became its property and did its will and IT IS STILL HERE]]
* 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.
* [[http://scp-wiki.wikidot.com/scp-899 SCP-899]]. "A psychic and telekinetic phenomenon that most commonly manifests as groups of hostile phantom children." Then they went and exposed it to [[http://scp-wiki.wikidot.com/scp-573 SCP-573]]. To give some hint of how "successful" that experiment was, [[http://scp-wiki.wikidot.com/diary-573 this]] is what happens when a perfectly ordinary person uses 573, and taking a picture of it with SCP-978 resulted in a [DATA EXPUNGED] and a note that "It appears SCP-573 is indeed sentient in any case."
** GOOD GOD THE PICTURES. Seriously, they're [[UndeadChild freaking scary.]]
* [[http://scp-wiki.wikidot.com/scp-604 SCP-604]]. What makes it particularly bad is that it has no apparent effect on the users, meaning they chose to use it ''as they did of their own accord''. There are extensive records of what the thing can do, because its former owners charted their progress. And when they succeed...
---> (a waiter comes in pushing a cart with a wooden box on top. The box has several slots and holes opened in it, and tubes trail out, connecting to IV bags and tiny batteries. A mewling comes from within)
---> (The box is lifted up over a plate, put on it, and then pulled off. There is a flash of some kind of twisted, shaved animal, but then a human head appears.)
---> (the human head is that of a man around thirty five, with thick black hair and sideburns. He has extremely pale skin and dark circles under his eyes. He is severed at the neck, which reveals muscle and a bloody hole.)
---> Head: Where am I? Who am I?! What the hell is going- (Begins looking around and turning up, down, and to the sides) Everything seems at a weird angl- hey, what are you doing! Get that knife away from me!
---> Waiter: Bon appétit, gentlemen.
---> Head: (begins screaming)
* [[http://scp-wiki.wikidot.com/scp-847 SCP-847]]. {{Uncanny Valley}} aside, the "[DATA EXPUNGED]", the attacking of all females in the area, and the victim being killed by 'massive blunt trauma' all lead to some unsettling implications.
* There is something distinctly disturbing about [[http://scp-wiki.wikidot.com/scp-914 SCP-914]]. Testing shows that in spite of its supposed lack of sentience, it seems to have a rather twisted sense of humor, and on multiple occasions the "very fine" setting, which refines something to its most perfect form, has produced a (mercifully inanimate) replica of SCP-682, suggesting that it may have a "thing" for the beast. The fact that it knows 682's "home phone number" doesn't help matters.
** Testing of [[http://scp-wiki.wikidot.com/scp-978 SCP-978]] on SCP-914 indicates that what 914 really "wants" is to have a sixth setting on its control knob, that goes ''beyond'' Very Fine...
** Every time someone tries to run something organic through the "Very Fine" setting, it gets all "[DATA EXPUNGED]". But some of those have rather... telling... notes relating to "cleanup," and they've banned any further attempts to use it on living things.
* [[http://scp-wiki.wikidot.com/scp-342 SCP-342]]. It takes the form of a ticket to some kind of public transit, and once you get on you can never get off. Just... read it.
** "And her never returned, no he never returned, and his fate is still unlearned. He shall ride forever 'neath the streets of Boston. He's the Man Who Never Returned."
* [[http://scp-wiki.wikidot.com/scp-400 SCP-400]] is a phone booth that can contact anyone. [[http://scp-wiki.wikidot.com/scp-519 SCP-519]] is a phone containing a voice that is on permanent Sarcasm Mode. When they tried to ring 400 through 519, 519's response was, and I quote, "Ooooh, boy...". On the other side, 400 rang, and a guard picked it up, only to be pulled apart by an unseen force. Then there was a containment breach resulting in the entire site around being locked down and everyone terminated.
* [[http://scp-wiki.wikidot.com/scp-826 SCP-826]] is a very ordinary looking set of pewter dragon-head bookends, but if you close the door of the room, put a book or DVD between them, and open the door, the doorway will be a portal to the world of the book or film. It seems almost to be a joke entry, with a note about a researcher who was demoted for (apparently) planning to do very naughty things to a female Disney character on a DVD. But what if you tried it with the Necronomicon? And this thing is listed as "safe." Not Euclid, not Keter. "safe." Brr.
** Safe only means that the SCP can be reliably controlled, as long as you have appropriate protocols, and aren't inherently hostile to humanity. This is an easy mistake to make, made worse because the standard definition of safe does apply to some of them. And then others kill you in horrible ways, but are easy to keep under control. Good luck guessing which is which.
** And if you don't find the bookends within the story in time, you can ''never escape''. You get {{Mind Rape}}d into a background character...''forever''. And you can't even choose which part of the story you arrive in. So if you arrive at the very end...tough luck.
** Dear God, imagine what would happen if someone put a DVD copy of MarbleHornets in between SCP-826? ... shit.
** Do remember that even if you put in something so horrible that no one could possibly survive it, its effects will still be confined entirely to one room. All you have to do is warn people not to go in.
* [[http://scp-wiki.wikidot.com/scp-701 SCP-701]]. Especially Incident Report SCP-701-19██ and that photo.
** Granted, that's an unnerving photo. But there's something amusing about how the report is basically a cross between a tenth-grader's meticulous school report on The Scottish Play with a ''literal'' KillEmAll ending.
** The URL for the Incident Report betrays what date 19██ is: [[spoiler:1997]]. Also, the state mentioned as the place where the video tape was recovered is [[spoiler: Ohio]]. It seems those ██s aren't impenetrable after all.
* [[http://scp-wiki.wikidot.com/scp-740 SCP-740]] will make your skin crawl. An infection that eats you alive, and then makes spiders burst out of your skin (Hopefully you'll be dead by then, if not you have about 20 minutes to live). Then they EXPLODE to create more infected with the spores they release.
* [[http://scp-wiki.wikidot.com/scp-610 SCP-610]]: It's like the [[DeadSpace necromorphs]] and The Flood rolled into a single package. Squick warning, obviously; the page image is [[BodyHorror especially bad]] (or [[NightmareFetishist awesome]]).
** Even worse is it`s official nickname: ''The Flesh that hates''.
* [[http://scp-wiki.wikidot.com/scp-439 SCP-439]]: It's a parasitic insect resembling an earwig that will ''[[BodyHorror turn your body into its hive.]]'' It enters your body ''[[ParanoiaFuel while you're asleep,]]'' and then, in a process shown to be ''very'' painful, causes your body to deform into a spherical mass while the insects ''eat you alive from the inside out.''
** And then there's the addendum at the end, which shows an SCP researcher operating on the "bone hive", and finding that the eyes had not yet been eaten. She shined a flashlight on them, and ''the eyes followed the beam.'' Think about the [[AndIMustScream implications.]]
* 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.''
** On the other hand, considering the world evidently still exists, whatever he's doing has worked so far.
* [[http://scp-wiki.wikidot.com/scp-804 SCP-804]]: A piece of "art" that, when activated, slowly but surely kills all humans and destroys all man-made works in an ever increasing radius around it. The only saving grace is that said artwork is not immune to its own effects. However, the most nightmarish element of this SCP isn't its potential to destroy the world. No, the scariest part is that, according to the former lead researcher, Dr. Sorts, [[NotBrainwashed the SCP has no memetic influence on people]]. The people who created and activated a device that would wipe out humanity did it because, in Dr. Sorts' own words, ''they wanted to do it''. That the SCP Foundation transferred Dr. Sorts to another project and is continuing testing for a memetic component means either 1) the Foundation wants to be absolutely sure that no mind control is involved or 2) ''even the Foundation'' doesn't want to believe that there ''really'' are people in the world evil enough to murder humanity entirely of their own free will.
** The people "evil enough to murder humanity entirely" were well-intentioned extremists, at least the original ones who sacrificed themselves. As in, they wanted to get rid of humanity because they thought it had a greater net negative than positive effect on other lifeforms. Meanwhile, the Foundation has terminated or is trying to terminate several lifeforms for the same reason (and real life humans do this all the time with diseases, though with other life the extinction we cause tends to be accidental). So when you think about it, the creators of the SCP-804 merely had the same views on their fellow humans as most humans do on lifeforms that threaten them. You could argue that the SCP-804 creators are more evil because they have betrayed their own species, if you like... or you can argue that their motivations are actually more objective, since their views on what lifeforms are more harmful aren't determined by what benefits their personal continued existence. Either way, thinking about this for long periods of time is a bit like reading SCP-079 (an increasingly rational and objective computer that nonetheless clearly hates humans, if not all life), in that it has a creepy "but what if the SCP is RIGHT?" air to it.
* [[http://scp-wiki.wikidot.com/scp-354 SCP-354: The Blood Pond]]. It's a pond in the Canadian wilderness that is full of a liquid similar to blood. Highly dangerous creatures emerge from it from time to time; most of whom have nothing in common. And according to one SCP agent, it's alive. And intelligent. And angry. ''[[spoiler: And growing]]''.
** The fact that a seemingly normal human emerged from the pond at one point for ostensibly diplomatic reasons and was shot on sight probably didn't help on the "angry" front.
* Nearly every Keter-class SCP could be considered HighOctaneNightmareFuel. Given that the criteria for Keter classification are: 1) it's too valuable, dangerous, or invulnerable to be neutralized at present, 2) it's an extremely significant threat to humanity, civilization, and/or ''reality'', and 3) ridiculously extensive and precisely followed containment protocols are required to keep the SCP isolated and secure (and even then it may only be a matter of time before it gets out of control)...
* [[http://scp-wiki.wikidot.com/scp-120 SCP-120]] is a pink kid's swimming pool that works as a PortalPool, cycling between 11 locations each time you send someone through. The 11 locations include the 5 Lagrange points. Which are in space.
** It's a convenient way of teleporting, though, except for the Lagrange points. So they simply... cause it to cycle through them. Using D-class personnel.
** Also, it was discovered because of "reports of missing children". [[KillItWithIce Think about]] [[KillItWithWater what happened]] [[ShiftingSandLand to those]] [[ThrownOutTheAirlock children]].
* [[http://scp-wiki.wikidot.com/scp-662 SCP-662]] is a silver bell that summons a friendly, polite butler named Mr. Deeds, who will gladly perform required services by asked by the ringer, within reasonable limits. He'll fetch you a sandwich, but not one made of human flesh, and he'll bring you a grenade, but not a nuclear bomb. Seems fairly harmless, right? [[spoiler: Then they asked him to assassinate a D-class personnel, which he did with [[AlmightyJanitor disturbing precision with a buck knife]].]] Suddenly, Mr. Deeds doesn't seem like the nice, friendly fellow we all think he is....
** He might very well be harmless, but read the end of the [[http://scp-wiki.wikidot.com/662-l1 interview log]], and the interrogation by Agent Graves. [[spoiler: So, they kill him thoroughly, perform an autopsy on him, discovering nothing terribly interesting about him, and then they "permit" his body to vanish.]] Shortly thereafter, he is summoned, ready and willing to perform his duties. So, he's nigh omnipotent, willing to perform any service or retrieve any object, within his capabilities, and [[spoiler: he cannot be killed.]]
** I actually think this says far more about the way the Foundation deals with D-Class personnel. They are considered so inconsequential that Mr. Deeds will consider nothing much to kill them. Again, the Foundation is ''almost'' worse than the stuff they contain.
** ''Why'' can't Mr Deeds explain how he does what he does, even under torture, and why does he appear so uncomfortable when asked? The photo of him from the Desire Camera showed him exactly as he was, posing for the photo, which suggests his greatest desire is to do what he's instructed to do. Is he so uncomfortable when asked where he goes and where the items come from because he's unhappy that he's literally unable to explain, or because something worse will happen to him if he does? Also, he was disturbingly calm when offering to be fed to SCP-682.
* [[http://scp-wiki.wikidot.com/scp-668 SCP-668]], [[spoiler: the knife used to kill Kitty Genovese]], is utterly terrifying to people who don't deal well with helplessness. Read about what it takes in order to reclaim it if lost. Now think about what that would enable any garden variety sadistic creep to do. That thing's pretty much a catalyst for a wide variety of end of the world scenarios.
* [[http://scp-wiki.wikidot.com/scp-597 SCP-597]]. [[FreudWasRight The Mother loves you.]] [[MindRape You will love The Mother.]] [[FateWorseThanDeath The Mother will provide for you forever.]] Why this powerfully telepathic...''thing''... has not been terminated or even properly contained is a mystery.
** Probably because it's ''FetishFuel'' for some of the Foundation's higher-ups.
** Let's count everything that's wrong with SCP-597 or "The Mother", shall we? Well, for starters there's what it is, a massive ball of mammaries, nipples for every species of mammal, and no matter what the milk will always be perfect for whatever mammal's drinking it. Most mammals can't resist it. Bats, rodents, cats, dogs, all of these can be found sucking on the thing, and refuse to let go; it's described as being a sexual, psychological, and hunger compulsion all at once. Also, the male staff have sex with it. Regularly. So regularly in fact that they don't do anything to discourage it. The thing is always covered with slobber and semen, which D-class personnel clean. Of course, that just means they get brainwashed faster than everyone else. They also have the task of collecting the milk for study (which they often sneak whole bottles off for themselves). All staff at its facility are affected. In early stages, people who quit smoking for years have a 100% relapse rate, people binge on snacks (especially dairy products) or chew gum. So much gum that they choke on it. Later stages the behavior gets even more extreme. Formerly heterosexual woman begin to engage in lesbian sex, some men become rapists, others latch onto large breasted women as surrogate mothers. If things are allowed to progress this far, all milk samples from The Mother will be fought over by the staff. Next staff begin to regard the mother with superstitious awe, worshiping it with incense, food offerings (even though it doesn't eat) and animal sacrifice. One scientist circled every one of the nipples with a red marker and wrote the word "life" next to them before killing herself. Then they begin to revert into child like states, losing bladder and bowel control, masturbating constantly, calling it "mommy", crawling on all fours and talking like toddlers, before finally curling up and joining the rodents and bats in suckling. The milk will keep them alive the rest of their adult lives, and they will be in blissful happiness, but their muscles will atrophy, and their teeth will fall out, and they will experience digestive problems from the sudden switch to a liquid diet. There is no way of stopping this. Even if you send them away from it, the effects are permanent, and they have several data expunged section describing staff that took this mental illness home with them (including one where it was implied that a man raped and killed his own mother for "not being good enough"). The only thing they can do is constantly rotate, and kill staff members.
** Even worse: The Mother ''can'' be destroyed, but the ones who have the authority to do so use The Mother as a sexual experience, ordering a Class D to pry them off after an hour of suckling.
* [[http://scp-wiki.wikidot.com/scp-087 SCP-087]] is a never-ending platform staircase that resists attempts to illuminate it, and descending one flight of stairs lets you hear a child crying for help about 200 meters down. The people sent down one by one found something else instead...
** Plus, they sent four missions down into that staircase and you can only read the first three and they get progressively worse. But after the fourth mission it started to knock on the 'door.'
** Also terrifying are the effing ''pictures'' on the thing's page. Especially the first one. It's like one of those "when you see it, you'll shit bricks" demotivators.
** And that's not all. If you try to upload the first image to a imagehoster (you know, to avoid hotlinking), the face in the uploaded picture is ''gone''.
** There is now a [[http://dl.dropbox.com/u/10887020/SCP/SCP.zip game]] of SCP-087. Enjoy.
* 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.'' [[http://scp-wiki.wikidot.com/scp-042 SCP-042]] in particular seems to be written specifically to highlight the cruelty of the Foundation, [[spoiler: 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 ForScience. Yeah. It makes me sick too.
** 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.
* [[http://scp-wiki.wikidot.com/scp-596 SCP-596]]. That it can heal any injury would have been a great help for the Foundation, if it weren't for the fact that any physical contact with it will leave the victim permanently stuck to it and unable to move it themselves unless another person makes physical contact with the statue, killing the original subject. What's even more nightmare-inducing is that absolutely no other method can separate the two: whenever a victim is surgically removed from SCP-596, they will die and a new body will grow from the parts still attached to SCP-596.
** What's even worse is how the Foundation takes advantage of its abilities. The victims are used as ''reusable organ donors''. Since anesthetic isn't an option thanks to the SCP's powers, the Foundation used to resort to decapitating the victim in order to temporarily incapacitate them during the harvesting. Now they just empty their skulls to keep them from screaming.
* Not as horrifying or deadly as the other [=SCPs=], but [[http://scp-wiki.wikidot.com/scp-613 SCP-613]] ability to make contaminated organisms lose all color and become black and white over the course of a few days and leaving the carriers unable to perceive or remember what colors are, brought shivers to me. Luckily any healed former carriers can develop immunities to the disease.
* [[http://scp-wiki.wikidot.com/scp-204 SCP-204.]] 204 comes in two parts: 204-1 is a colony of nano-machines that follows around 204-2, protecting him/her from harm. 204-2 is a child aged from 4 to 14, with a history of being abused, who can control 204-1. When 204-2 turns fourteen, 204-1 finds a new child to protect, and, if the former 204-2 is mentally stable, the former 204-2 is given a Class-A amnesiac and put into a foster care program. That's not the HighOctaneNightmareFuel. The real HONF comes from an addendum that explains that due to 204-1 freaking out if there isn't another suitable child to imprint on if needed, the Foundation have a group of suitable candidates. However, if they really need candidates quickly, they can enlist some more candidates who don't fit the protocol- i.e., they are of a suitable age (preferably under ten), but they don't have a history of abuse. The Foundation will then '''turn them over to 'caretakers' which will consist of D-class personnel convicted of violent crimes, child abuse, and pedophilia'''. It also says that the procedure for hiring the 'caretakers' is the same one for finding people to perform Procedure 110-Montauk on SCP-231. Jesus Christ.
** Oh, and as an aside? SCP-204 will psychically manipulate whatever it's guarding into taking dangerous actions so it is forced protect what it is guarding, and thus allowed to feed. The SCP literally forces the child into danger so it can feed.
** And on top of that? Right now it's guarding a '''complete sociopath''' who is very quick to threaten people with the hungry, amoral nanomachines!
** And as if to top the whole thing off, 204 is ''ludicrously'' powerful. The initial capture required an ''Abrams tank'' and an '''AC-130'''. Yes... to capture this thing, you need not only one of the most powerful armored vehicles in the world, but also DeathFromAbove UpToEleven.
* [[http://scp-wiki.wikidot.com/scp-787 SCP-787]] is rather mundane (average scenes of grisly horror and cannibalism with some poltergeist activity), but the real chiller is '''"TO BE SORRY"''' endlessly repeating on the flight log.
* [[http://scp-wiki.wikidot.com/the-great-short-story-contest The Great Short Story Contest]].

* [[http://scp-wiki.wikidot.com/scp-800 SCP-800]] is an antique scroll painting that regularly changes to reflect current political relations or tensions in East Asia. It currently depicts two soldiers in combat, mirroring the tenuous state of relations between the North and South Koreas. The Foundation once performed a test to see if adding objects into the painting had any kind of effect; an expert in East Asian art added a quiver of arrows to one of the soldiers. Three days later, North Korea did...something that ended up purged from the records and stopping all further testing on SCP-800. The arrow metaphor gave me a [[EmptyQuiver pretty good guess]] [[NukeEm what happened]]...
** It gives a date of May 25th, 20██. Now, scrolling through The Other Wiki, I found [[http://en.wikipedia.org/wiki/2009_North_Korean_nuclear_test something that happened on May 25th]].
** Presumably, adding the arrows made the nuclear test occur. That's not the worst thing; there's mention that it once took the appearance of a Khmer stone carving. The description of said carving has been expunged. Predictable, considering [[http://en.wikipedia.org/wiki/Khmer_Rouge what happened...]]
** Almost all SCP [REDACTED] or [DATA EXPUNGED] marks are indicative of HighOctaneNightmareFuel or something else really gory. Most refer to something that the Foundation did, or something that an SCP did. Not the description of the Khmer carving–this was a non-fictional event carried out by real human beings. And the SCP Foundation expunged its data. [[HumansAreBastards Yeah...]]
* [[http://scp-wiki.wikidot.com/scp-823 SCP-823]]. A theme park that killed over 200 people in horrific ways (such as somebody in a mascot costume being filled with stuffing). Anybody sent in after that dies. So they can't find out what's going on, and that can't contain it because it's ''growing''.
** [[NothingIsScarier "Unable to determine context or content of above photograph."]]
** The last paragraph in the "civilian deaths" section. Someone was completely dismembered... and, at the very end, it's mentioned that he was still alive when they found him like this.
** The commander of the Mobile Task Force team was found dead from suicide. That's not the scary part. The cause of death was from [[EyeScream "forced sexual entry through left eye"]]! Think about that for a second.
** If you're savvy enough to realise some of the images are of a theme park that was supposed to open in Chernobyl, then it becomes...slightly less terrifying.
* [[http://scp-wiki.wikidot.com/scp-741 SCP-741]] is a sunken Russian submarine split into three pieces and guarded by the Foundation. The HighOctaneNightmareFuel? An attached interview with an American spy that said that the sub was carrying some kind of new weapon that not only made a bioweapons researcher sick, but that the Soviet couldn't safely control -- they sent the sub away to get rid of whatever it was.
* [[http://scp-wiki.wikidot.com/opportunity-knocks Opportunity Knocks]]. Apparently based on a recurring nightmare of the author's...
* During the experiments with SCP-914, they put in ''IWannaBeTheGuy''. Setting on Rough made up the games used for IWBTG, simple enough. 1:1 made Kaizo Mario World. Fine gave them ''Super'' I Wanna Be The Guy, which is undoubtedly near-impossible. Finally, Super Fine had all information denied by the O5's. This means that this... '''thing''' that resulted from putting IWBTG in SCP-914 has been formally denied existence of by the ''Foundation's directors''!
* [[http://scp-wiki.wikidot.com/wednesday-1 This story]], especially the ending. Watch me fly!
** [[NothingIsScarier The fact that you didn't list which SCP caused it is really freaking me out.]]
** With all of the parts written, the final ending seems to be something more akin to a CrowningMomentofHeartwarming.
* [[http://scp-wiki.wikidot.com/scp-734 SCP-734]]. Awww, it's a cute baby boy. And if you touch him your body starts to break down and flake away.
* [[http://scp-wiki.wikidot.com/scp-058 SCP-058]] resembles a ''bovine heart with tentacles and spikes''. It also talks, although whether that's a good or bad thing depends on how creepy you find poetic ranting.
* [[http://scp-wiki.wikidot.com/scp-290 SCP-290]] reads like a love letter to the BodyHorror sub-genre: it reconfigures your body in wild ways while keeping you alive. The Experiment Log Addendum includes the poor test subject's head "slowly embedding itself into his thigh, both eyes absent", and a strong implication that -- horribleness warning -- the restructuring of his internal organs had re-routed some of his waste through his chest cavity.
* 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.
* [[http://scp-wiki.wikidot.com/scp-775 SCP-775]] are ticks as big as nickels.
** "[[spoiler: Hosts will eventually be fully hollowed out, with only the outer layers of skin remaining]]." Thank you, SCP, because [[{{WhyDidItHaveToBeSnakes}} regular ticks weren't horrible enough.]]
* [[http://scp-wiki.wikidot.com/scp-370 SCP-370]] is an memetic hazard that spreads via sight, knowledge about said hazard, sight of the end result, etc. Don't read it if you plan on getting sleep.
** Not to mention that it's implied to be created by [[GodIsEvil God]].
** Furthermore, people infected with it rewrite the page to spread it. How do you know you haven't been infected yet?
* [[http://scp-wiki.wikidot.com/scp-781 SCP-781]] is a person who involuntarily manifests his own nightmares, and is killed by them an average of three times a week.
* [[http://scp-wiki.wikidot.com/scp-035 SCP-035]], a comedy mask that constantly secretes a corrrosive substance from its eyes and mouth. This calls for a glass containment since glass dissolves slower than everything else. People that see it want to put it on and when they do they are possessed by it as their body slowly decays, even past the point where (mechanically) they shouldn't move. The entity has complete knowledge on [[MindScrew human psychology]] and uses this along with [[AffablyEvil charm]] and telepathy to [[HannibalLecture convince ''anyone'' to do anything]]. [[ItGotWorse It gets worse]]. After a while, they decided not to give it any more hosts, realizing the potential this thing had. It starting driving people around the cell to suicide and depression. They coated the walls with an alloy that blocks telepathic suggestions, and it started decaying the walls with corrosive blood. Now, its cell is almost impossible to enter, due to the dangerous phenomenon within. [[BeyondTheImpossible It gets worse.]] The entity also shows interest in [[OhCrap 682]], whose regenerative abilities could counter the mask's corrosive decay, giving it a permanent host.
* [[{{God}} SCP-343.]] He's God, how can he be scary? If he's God, that means he is (however indirectly) responsible for the [=SCPs=]. Possibly including [[OmnicidalManiac SCP-682]].
** Now, now, in 343's defense, he/He denied having anything to do with 682, and in fact cannot see it. This gives a new level of terror. 682 vs. 343, and 682 would win.
*** 682 charged right through 343 without either of them noticing. Neither one can directly sense the other in any way.
** It's pretty clear that 343 isn't "God", just an incredibly powerful being. Plus, God [[http://www.scp-wiki.net/gdp2-second-language is not feeling like himself these days.]]
** Either way, he can't touch 682 and is still more than capable of messing you up something fierce. 343's exact identity is left reasonably open-ended, so the reader can draw their own conclusion.
* [[http://scp-wiki.wikidot.com/scp-966 SCP-966]]; an invisible humanoid ''thing'' that hunts by making you unable to sleep. Imagine it; you're in your house, at 2 AM and you are dead tired, but for some reason you just can't sleep. The night goes on and on, you keep moving uncomfortably in the bed, and nothing. Comes 6 AM and you have to get up to go to work. The whole day you are just shambling through the world like a zombie, trying desperately to at least have a little nap, but ''you simply can't get asleep''. When you're finally so tired you can't even move, a sharp pain comes from somewhere on your body and all you see ''is your flesh being ripped off with no clear reason as to why''.
** YOU SHOULD HAVE WARNED US ABOUT THE PICTURE. JESUS CHRIST.
** More squick than terrifying, but when someone took a picture of one of those creatures with SCP-978 (the Desire Camera), it showed a picture of two of them ''mating''. Just... try to imagine those things doing that... *shudder*
* Four words: [[http://scp-wiki.wikidot.com/scp-426 I am a toaster]]. God, reading my page is still scaring me.
** To elaborate, I am a toaster that makes people refer to me in the first person. Nobody's ''ever'' been able to refer to me in the third person, no matter what they do or don't know about me. Eventually, they completely forget who they are, and usually die when trying to emulate the functions of a toaster (one person died because she ingested so much bread that her stomach ''bursted''). [[http://scp-wiki.wikidot.com/that-goddamn-thing This short story]] also demonstrates my potential for creepy.
* [[http://scp-wiki.wikidot.com/scp-455 SCP-455]]. A ghost ship.
** It's more like an EldritchAbomination ship. For example: Weird temporal distortions, messed up interior dimensions, not really having any clue what goes in inside, things [[ItGotWorse getting worse]] for exploration teams, and so on and so forth.
** Thank you. I was having trouble putting into words ''exactly how messed up'' this thing ''is''.
* Dr. Bright. Aside what he did to his own brother, he is a god of FridgeHorror. Just look at [[http://scp-wiki.wikidot.com/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation 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.
** [[http://scp-wiki.wikidot.com/forum/t-115448/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation#post-934222 Word Of God]] says that the list is not in-universe. So, although Bright ''is'' an asshole, he's not an completely irresponsible asshole.
** But then again, half the time he ''is'' a monkey, so it kinda makes sense.
** Bright's own [[WhoWantsToLiveForever life]] is a FridgeHorror in and of itself.
* [[http://scp-wiki.wikidot.com/scp-363 SCP-363]], the centipedes that grow enormously in the dark. And not into giant centipedes, but into horrific tentacled monsters. To top it all off, [[spoiler:they have the apparent ability to infect people and [[BodyHorror transform them into more of them]]. One of these infectees are a mobile task force agent, who escaped and is possibly out loose into the world.]]
** Y'think that's bad? [[spoiler: The page says F. Tell is to be stopped at all costs. It does not actually make note of him being stopped. Which turns that "possibly" into a firm "definitely".]]
* [[http://scp-wiki.wikidot.com/scp-632 SCP-632]], a species of tiny, hermaphroditic, self-fertilizing spiders. Their eggs are light enough to float on almost non-existent breezes. When they land on warm skin, they hatch, burrow into your ''sweat glands'' and travel through your blood vessels to your brain. Then they burrow in ''THERE'' so they can feast. This causes a minor headache, which is alleviated by light tapping on the closest part of their head. As they continue, the headache gets worse, meaning the host has to hit their head harder. Eventually this leads to ''caving your own skull in''.
* [[http://scp-wiki.wikidot.com/scp-700 SCP 700]]. There was a hole here. It's gone. Now the hole's back, but the person who fell in is gone.
** [[spoiler:You really want scary? The goddamn face picture on the left MOVES, and it's only action is a quick half-second look directly at you.]]
* [[http://scp-wiki.wikidot.com/scp-096 SCP-096]] is a creature who is docile until you look at it's face at which point it will charge at you and kill you. The bad part about this is this works even with pictures and it will track you down no matter how far away you are. Also there have been pictures spread on the internet and the SCP Foundation is still in the process of removing them.
** To understand how horrific this is read [[http://scp-wiki.wikidot.com/incident-096-1-a Incident-096-1-a]] in which SCP-096 tracks down someone who saw it's face in a picture in which its body was only 7 pixels. So you can be looking at a picture and never notice it's there.
** Oh, and did we mention that when enraged, it's invincible? And that it's capable of bringing down an AWACS plane? And that it doesn't just kill its victims, it also [DATA EXPUNGED] them, leaving no trace of the body?
** There is one bit of good news: [[spoiler: -096 has been scheduled to be terminated.]] Though it took [[spoiler: letting the creature escape and wreak havoc on a highway, a small population center, and a military aircraft, ending with the execution of the scientist who arranged for the breach to happen]] to convince the [=05=] to act.
* You know you're dealing with some master writers when they can make ''cups'' ParanoiaFuel. [[http://scp-wiki.wikidot.com/scp-198 SCP-198]], a cup that can teleport and pretend to be other beverage containers. When you pick it up, it instantly bonds with your skin and cannot be removed, even by amputation. You rapidly become dehydrated unless you drink from the cup. What's in the cup? Human body fluids, like spit, sweat, bile, mucus, and...some less pleasant ones. Also, since you dehydrate so fast, your only hope is to chug everything in the cup constantly. I'd make a 2girls1cup joke here, but I doubt it would help.
* [[http://scp-wiki.wikidot.com/scp-182 SCP-182]]: A nice, cheerful guy who wants to be friends. Oh, and did we mention that he's deaf, mute, and horribly scarred, and he compensates for the first three by involuntarily riding shotgun on your senses when you get within ten meters, and if you stay around him there's a 97% chance you'll go insane? And he knows this. And he can't do a thing about it.
* [[http://scp-wiki.wikidot.com/scp-478 Well, how bout the Tooth Fairies?]]
* [[http://scp-wiki.wikidot.com/scp-600 SCP-600]]. The things it does with victims... Do Not Want.
** Not to mention the picture, which in a real-life context as a mugshot would represent in a detached manner a degenerate white trash sex offender and/or serial killer, while it screams, especially with its eyes, to this troper, "CompleteMonster with RAPE FACE!"
* [[http://scp-wiki.wikidot.com/scp-084 SCP-084]]. The static tower. It causes distortions of reality within its area of effect, trapping a small town within. They can't die, age, and have no need to sleep or eat. They also can't escape. One man was picked up four hundred meters from the city limits. He'd been traveling for ''six years''.
* [[http://scp-wiki.wikidot.com/scp-616 SCP-616]] is a prototype airplane. The emergency door opens on its own every 30 days, revealing what is essentially implied to be Hell. However, the worst thing you can do is let the door ''close'' before the manifestation is over...
** As scary as that entry is now, it was actually a lot worse when it was first written. [[http://replay.waybackmachine.org/20090316131454/http://scp-wiki.wikidot.com/scp-616 See for yourself.]] Among other things, it tells you exactly what was on the recording.
* [[http://scp-wiki.wikidot.com/scp-456 SCP-456]] are bedbugs. When they bite you, they produce narcotics in your brain, causing you to feel increasingly sleepy until you sleep constantly, causing you to die of malnutrition. They can't be distinguished from ordinary bedbugs, and you probably won't know they're 456 bedbugs until it's too late.
** Even worse, they exposed four D-class to the bedbugs. After expending three of them, they put the fourth one on a regimen of IV nutrients, blood transfusions, and narcotics antagonists. He's been asleep for a long time. The number of days is blanked out, but it's a triple digit number...
* [[http://www.scp-wiki.net/scp-686 SCP-686]] By itself, it's not scary, but once you think about the implications, you will freak out. 686 is just milk, except it contins an infection that causes mammary glands to devlop in mammals, even males. If milked regurlay, the diesase won't advance any further. If left unchecked, however, your ''entire torso will become an gigantic udder.'' Not only that, but because you have to eat all the time to keep your metabolism up, ''you'll become nothing more than a docile animal.'' Just imagine what a sick mind could do with that. On the other hand, you could consider it FetishFuel.
* [[http://scp-wiki.wikidot.com/scp-860 SCP-860]] seems fairly ordinary by SCP standards - a blue key that leads to a blue-misted forest with some unseen creature stalking you as you walk through it. The ''real'' chiller is the end of the last exploration log and that very last bit of audio.
* [[http://scp-wiki.wikidot.com/scp-624 SCP-624]] seems on the surface to be one of the more benign SCPs. It is an ordinary MP3 player which, if used, plays the users favorite music, covered by a more musically talented version of the user. But if someone with no musical preferences uses it, it plays the users soul. Meaning that you hear everything you have ever felt and heard and thought, including the bits you are ashamed of, right up to and including your own death.
** Death nothing. The examples provided in the main SCP page for 624 state the last track continues ''into the afterlife.'' Specifically, continuing ''as the soul is tortured in hell.'' This happens '''Twice.'''
* [[http://scp-wiki.wikidot.com/scp-750 SCP-750]] is a pair of contact lenses made by The Factory. When you put them on, it displays a variety of changes, like food becoming piles of limbs and gore, walls becoming coated in biofilm, and the skies becoming red and black. Victims who have the glasses on for too long usually get schizophrenia or PTSD. Real scary part? The lenses LET YOU SEE THINGS AS THEY REALLY ARE.
* Goddamn it, the whole ''website''. The titles are very mundane numbers and stuff, so...you never know if you're clicking on something funny, [[{{Squick}} squicky]], or an insanely [[HighOctaneNightmareFuel fucked-up]] EldritchAbomination that will keep you awake for ''days''. And the ''pictures''...oh, god, the pictures...
* According to [[http://scp-wiki.wikidot.com/document-recovered-from-the-marianas-trench 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....
* How about [[http://scp-wiki.wikidot.com/scp-528 SCP-528]]? They're little plastic containers containing silly putty that copies whatever image of a person is pressed onto it. Sounds harmless right? Wrong. Whatever happens to the picture happens to the person. The tests are horrific, the first one involving a D class having first his arm stretched unnaturally long, which is apparently painful and then torn off. The second subject is crushed into a ball and suffocates on his own flesh. The third one however is the worst of all. The putty is dipped in boiling water and the D class actually melts until he suffocates on his own nose.
* [[http://scp-wiki.wikidot.com/scp-736 SCP-736]]. It's [[CommandAndConquer Tiberium]], except that it ''feeds on your blood.''
* [[http://www.scp-wiki.net/scp-939 SCP 939]]. Read the whole page and all its included documents. [[spoiler:They are these ''things'' that attack people and breathe amnesiacs. Doesn't sound scary? Read the document, "Reproduction of SCP-939." The whole thing. The audio log is a blend of HighOctaneNightmareFuel, TearJerker, and just a bit of AdultFear. Those things are sentient and, when they're young, they ''are just like small human children''.]]
** The worst part? Putting them into 914 on "Fine" and "Very Fine" ''killed'' them–in essence, they're '''supposed''' to be dead.
* 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. Maybe it's just me, but I find that terrifying.
* [[http://scp-wiki.wikidot.com/scp-772 SCP-772]]. More BodyHorror, except this time with bugs the size of your thighs.
** Elaboration: They're wasps, MadeOfIron to an extent where bullets and even ''fire'' are useless, with a stinger longer than they are. When they sting you, they inject eggs under your skin, which is described as being 'excruciatingly painful'. Read the whole thing, if you can stomach it.
*** It's also implied that they're more likely to go after you the more afraid of them you are.
* [[http://scp-wiki.wikidot.com/scp-592 SCP-592]]. It's a history textbook. From an alternate timeline. If you read it, you're absolutely fine, as long as you read about something that happened before June 15th, 1956, when the timelines diverged. Anything past that and your mind is warped -- you start remembering things according to the alternate timeline's history, not reality. Reading an entry covering within 2 months from June 15th, you get a headache and can recover. 2 years, you'll have panic attacks and minor mental illness for the rest of your life. 10 years, psychosis and dementia. Anything past that and your perception of reality starts to break down completely.
** It gets worse. People who start remembering history differently due to this book can be ''physically modified'' to match the book's history -- gaining scars and losing limbs in wars that never happened, for example. Worse still, a significant number of the articles mention known SCP objects, suggesting the divergence point is [[spoiler: the founding -- or rather, lack thereof -- of the SCP Foundation.]] (The timeframe is actually spot on for this theory.)
** The Foundation is using a complex system of computers to analyze the book, due to nearly anyone even looking inside the book going absolutely stark raving mad. They are effectively getting the computers to "learn" that history and tell us it in the most vague terms possible. One of the final entries on the page suggests something far, far more sinister is at work:
--> ''The image contains two (2) ADULT PERSONS standing, one (1) HUMAN CHILD sitting on a CHAIR or STOOL, and SCP-███. With 100% certainty the PERSONS in the image should have FACIAL FEATURES. [[TheBlank With 100% certainty the PERSONS in the image do NOT have FACIAL FEATURES.]]''
* [[http://www.scp-wiki.net/scp-930 SCP-930]]. It's an uncharted island. The birds around it, 930-1 attack anyone who gets close. They don't kill, just cause minor wounds. They're not trying to hurt you, they're trying to get you away from the island. There's something much worse there...
* [[http://scp-wiki.wikidot.com/scp-716 SCP-716]]. On the surface, it doesn't seem too scary- just some kind of ghost train, but that's until you get to the part about a boxcar filled with dead horses, or a tanker filled with human bile. Plus there's the fact that if it comes near you ''you're compelled to kill yourself''. And if you're on board the train when it gets too fast, it's likely that you're sent to another planet to die.
* [[http://www.scp-wiki.net/scp-870 SCP-870]]. Ever drop something and can't find it again?
* '''[[http://www.scp-wiki.net/scp-1000 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...
** And later on, they leave us this message:
--> [[spoiler:we forgive you;]]
--> [[spoiler:given choice for now, not forever;]]
--> [[spoiler:let us back in]]
* [[http://scp-wiki.wikidot.com/scp-517 SCP-517]] I became paranoid after having seen one of the pictures move (having been a .gif), so I have a tendency to quickly copy and paste the link to a picture to check if it'll spaz out in any way. The picture with the glass is a .gif, so I didn't stick around long enough to see if it would move.
* Why are all old photos in black and white? Not because we didn't invent color photography until relatively recently. Because [[http://www.scp-wiki.net/skybluesky we didn't invent COLOR until recently.]]
** Although that could become NightmareRetardant when you remember that that was the premise of one of [[CalvinAndHobbes Calvin's father's]] LittleKnownFacts.
* [[http://scp-wiki.wikidot.com/scp-993 SCP-993.]] It's like CandleCove as done by a MonsterClown - except Candle Cove didn't [[BrownNote brainwash children]]. In one episode the clown just stares at you. [[NothingIsScarier For the entire episode.]] What makes it worse is at in that next episode you can tell who he's really staring at: [[spoiler:''The SCP Foundation''. '''''[[ItCanThink It can think.]]''''' It is a sentient, evil ''television program'' and it knows who's watching. Even it's ''archived copies'' are aware. It knows the Foundation is blocking it's broadcasts and ''[[VillainousBreakdown it's pissed]]''. It's copies are kept on the Foundation, so he could easily learn about a memetic hazard and ''get creative...''.]]
** It already knows about certain SCP's, and how to breach containment for them. For all we know, [[OhCrap it may have already found one]]
** One short story on the site makes Bobble even scarier with TheReveal that [[spoiler:Bobble isn't just a television program. It's an EldritchAbomination that existed since the dawn of humanity and has spent all that time encouraging violence in humans. Its first act was to teach them the secret of fire. "Bobble" is just its most recent idea.]] In the same story, Bobble also reveals that [[spoiler:he's perfectly capable of killing people in the real world even in containment.]]
** Of course, the fact that its second-most-recent episode is entitled "[[ClusterFBomb FUCK YOU! FUCK YOU! FUCK YOU!]]" and is basically 30 minutes of extremely angry shouting from Bobble makes things a bit funnier.
* [[http://www.scp-wiki.net/scp-611 The living toothpicks...]]
** To elaborate: They are a species of botflies. Botflies are insects that nest in human flesh, with their larva feeding off the person and eventually burrowing out. These particular flies can impersonate toothpicks, and lay their eggs in the gums, eating their way out. [[{{Squick}} And there's a picture.]]
* [[http://scp-wiki.wikidot.com/scp-1100 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 [[EverythingTryingToKillYou plants, wild animals livestock and even pets]]. [[spoiler: It's implied that [[GaiasVengeance the Earth itself]] is creating the substance.]]
* The [=SCPs=] that [[WouldHurtAChild specifically target children]] really creep me out. 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...
* [[http://www.scp-wiki.net/scp-136 SCP-136]] is a doll. When you look at it for too long, you get {{mind rape}}d (in a way heavily reminiscent of ''physical'' rape) by a naked, insane, blood-covered ghost thing that inexorably floats towards you, laughing, before shoving its face right ups to yours and screaming before disappearing. It usually takes the form of a woman with an obscenely large mouth and oversized breasts. And now we're finding out that it can kill people...
* Dr. Wondertainment, and the fact that his/their SCPs are ''made for children''.
* [[http://scp-wiki.wikidot.com/scp-953 SCP-953]] is pretty freaking scary. The interview with one of the Foundation agents who encountered it is... yeesh.
* [[http://scp-wiki.wikidot.com/scp-089 SCP-089]] is a golden idol with a cavity in its chest that either causes or can prevent horrifying disasters; either way, they will only abate if Protocol M8 is fulfilled. What is Protocol M8? The statue names two people: SCP-089-A and 089-B. The foundation will send out a taskforce to convince 089-B to complete Protocol M8 out of her own free volition. Then comes the WhamLine. [[spoiler: "For each locution event, SCP-089-A is a healthy, unblemished human infant or child between eight months and six years of age, and SCP-089-B is that child’s natural mother. In all documented cases, at the time of the locution event SCP-089-B is alive, healthy and experiences a strong bond of trust and affection with SCP-089-A. Following SCP-089-B’s placement of SCP-089-A in the cavity and the ignition of the inflammable materials, SCP-089-A will burn and be destroyed over a period of two to five hours."]]
** Worse still, they haven't yet found someone to carry out Protocol M8 for the most recent prophecy, which is naturally hidden behind a "DATA EXPUNGED." In the past, when it took 49 days to find someone willing to carry out the protocol the casualties were in the thousands. (It's implied they could have been much worse.) By the date shown on the page it could be up to nearly '''12 years''' since the most recent prophecy. [[hottip:*:Which could be anything, including climate change, the war on terror, the global economic crisis, the Haiti earthquake, or the Japanese tsunami.]]
* [[http://scp-wiki.wikidot.com/scp-1042 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... [[spoiler: 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 minor accidents. Wait, did I say minor ? Sometimes they cause LETHAL accidents. AND THEY KNOW THEY'RE BEING WATCHED BY THE SCP AGENTS.]]
* And for Nightmare Fuel it is really hard to beat...[[http://www.scp-wiki.net/ethics-committee-orientation 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.
* And the [[http://scp-wiki.wikidot.com/and-then-i-died2 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.
* [[http://www.scp-wiki.net/scp-435 SCP-435]] is a meteorite to which a ''[[AlienGeometries very]]'' strange entity that is seemingly immaterial, yet does horrible things to solids that it touches, is bound. Also, if the meteorite isn't illuminated at all times, it can move around. We aren't told what happens when it intersects with landmasses or water, but apparently when it happened during its retrieval it had to be passed off as ''a nuclear test misfiring''. Apparently [[spoiler:it's an EldritchAbomination [[SealedEvilInACan sealed]] to the meteor who cannot see in the light, so he cannot find his way back unless it's dark, and the entity is its ''shadow'' on the material universe. Oh, and if it it goes dark for more than 90 seconds, it could [[ApocalypseHow cause an XK-class scenario]], and the backup plan is dumping the rock in another universe, which might actually break the seal.]]
* [[http://scp-wiki.wikidot.com/scp-710 SCP-710]]. Entering this city will cause you to ''slowly fade from existence.'' And it's totally irreversible once the symptoms manifest, to boot!
* [[http://www.scp-wiki.net/scp-515 SCP-515]] is a young man who causes celestial objects to move towards earth whenever he moves any part of his body. The good part is that he is asleep and is easily constrained, the bad part is that he sleepwalks and his very breathing counts as movement. The sheer impact SCP-515 has on this troper is that not only is it causing a potentially world-ending scenario, it isn't even trying to do so. In addition the feeling of inevitability really nags away on you.
* [[http://scp-wiki.wikidot.com/scp-895 SCP-895]] is not really all that scary to read about. A little chilling, but the really scary thing [[spoiler: is that live video feed. Watch it. [[SchmuckBait See what happens.]]]]
* 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 it's 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.
* [[http://scp-wiki.wikidot.com/scp-017 SCP-017]] is a shadowy figure roughly the size of a young child. Unlike some other dangerous SCP objects, it generally remains stationary and does nothing to actively harm anyone... until a shadow is cast upon it. When that happens, it will immediately leap at and engulf the object or person, then return to normal size as if they were never there to begin with. And all of the Foundation's attempts to discover what, if ''anything'' is within those shadows or where the victims go has been unsuccessful.
* [[http://www.scp-wiki.net/scp-020 SCP-020]] is a germaphobe's nightmare-- a mold that is invisible to humans unless videotaped or photographed, can grow all over your house and ''even on your body'', and changes your personality to make you more sociable so it can spread to all your friends.

** Even non-sentient creatures like animals tend to show some kind of change when photographed with SCP-978. The most horrifying possibility of all is that SCP-173 is either not alive, or a living being that lacks any form of consciousness or will whatsoever, ''yet continues to kill!''

* [[http://scp-wiki.wikidot.com/scp-112 SCP-112]] is an ArtifactOfDoom activated in the presence of any non-virgin or non-castrated person. And it has been stolen by radical Muslim terrorists. Get the idea?
** Well, now it's just a roller coaster that can bend space and time.

The scariest thing about the Wiki/SCPFoundation is that we can dedicate an entire page to it in HighOctaneNightmareFuel...
