It's commonly reiterated that the only real canon there is in the Foundation-verse is that there is no real canon. This only makes so much sense after one realizes just how many reality-bending SCPs there are.
Not to mention the alternative universes mentioned in many articles and the subject of a good number of SCPs.
SCP-261, the vending machine, has apparently infinite storage space. How is this possible? Well, one of the items dispensed was a packet of donuts with wormholes in them, so this thing clearly came from somewhere where wormholes can be controlled and used for storage.
Why couldn't the "Generally Nice Monster" kill 682? It was only specified to be able to kill 682, but not that it was capable of outlasting it or surviving a fight with it.
It still put up a damn good fight. The original 12-page short story became a 500+ page epic novel after SCP-682 was done with the Generally Nice Creature.
Also remember the people in going to the story can and do change the whatever the story in question is, mostly in just small ways, but that SCP has been shown not to be immutable.
Another possible explanation exists: throughout the numerous termination attempts, there are a couple research notes indicating doubt that 682 fits the definition of a 'living' being. In a strict interpretation of the word 'kill,' well...can you actually kill something that's not alive in the first place?
Actually it was stated that not only can it kill 682, but it will kill 682 if it ever gets near the damn thing.
It was known as "The Generally Nice, Friendly Thing That Can And Will Kill SCP-682 Permanently if it So Much As Spots That Damn Lizard". 682 probably got rid of the friendly thing's eyes, thus it couldn't spot him any more and kill him permanently.
One might also argue that since 682 isn't an Earth life form, it can't be taxonomically classified by an Earthling-based system and therefore isn't actually a "lizard".
One explanation for SCP-682's uncharacteristic friendliness toward SCP-053? It clued in to her secondary power of killing whoever attacks her, and the easiest adaptation for that was to get along with her.
Another theory: SCP-053's power reverses instinctive responses. What's the initial response for a normal human who sees a small 3-year-old girl? Take care of her and protect her. What's the initial response when SCP-682 gets near any normal human? Rip it to shreds.
Yet another one: not only is 53 one of the few humans who did not try to destroy it, every other human wants to kill 53. That makes 53 the only human 682 can trust and relate to.
Of course if everyone is constantly trying to kill SCP-682 that might mean that whatever wrongness SCP-053 is emitting is also being emitted by SCP-682.
Nope, they let an ordinary human child into its cell and while he screamed and cried he didn't try to kill it. What is possible is that the wrongness 053 emits to us is what we emit to 682.
You know how sometimes an entry will end with a humorous description/reference of someone using the SCP in a completely irresponsible, reckless, or unprofessional manner? Or how many of the senior staff are just a little bit crazy? There's a reason for that: when you work with or even know about so many things that can end the world or at least kill you in inventive ways, you've got to either laugh or cry.
The Mariana Trench Documents, crossing with Fridge Horror. The world actually ended several times, but the Foundation rebuilt it, people and memories and all. Why the title? That trench used to be a Bottomless Pit on land, near where the man who wrote the journal lives. It wasn't there before.
It seems odd for Clef to break his own rule about not talking with Type Greens when interviewing 531-D. Of note, however, is the fact that the purpose of the warning is to prevent the possibility of bonding with the target. A quick look at the interview logs with 531-D show that while Clef did indeed talk to 531-D, his intent was never to have a genuine conversation with 531-D; rather, his dialogue consisted of invectives that served the dual purpose of pissing off 531-D and painting him as a selfish brat, which would make the kill physically and psychologically easier, respectively.
SCP-085/Cassy getting more petting than kicking than most SCPs makes more sense when you remember her origin; she was accidentally created by an experiment between two SCPs, meaning that the Foundation, in a way, created Cassy. As a result, they most likely consider her their responsibility, as well as being aware of what she's capable of because they created her, so she doesn't require too much containment.
The "DRINK" from SCP-261's test log deprives you of your free will. It's a play on "drink the Kool-Aid", a slang term used to refer to someone who blindly follows an idea, belief, or orders.
SCP-1981 is an old Betamax tape that contains a recording of "Ronald Reagan Cut Up While Talking", which, as the title suggests, features varied ways Reagan is mutilated as he gives the speech. Ronald Reagan experienced an assassination attempt in 1981, making the identification number morbidly appropriate (and very likely an intentional choice).
In 978's test log, where Clef and Bright were photographed while in the middle of an argument, you may think that Clef is simply angry and the girl is just plain weird. Reading Clef's past however, you should realize Clef's desire that's far greater than just giving Bright the finger.
SCP-073 is THE Cain. He is invincible. Sound awesome? Well, he feels all pain inflicted on him, despite being able to recover. Now, imagine being stuck on Earth, incapable of dying. All your friends (the friends he HAD, anyway) would die, but you wouldn't. Eventually, when the earth is enveloped by the sun or an asteroid crashes into it or something, you'd be still alive, incapable of dying. You'd feel your skin being super-heated, you'd feel your body melting, yet still be alive. Eventually, you'd be lost in space, drifting forever, constantly feeling the pain of asphyxiation, never having your suffering put to an end unless you came across another planet with atmosphere, and even then you'd feel the pain of burning up and the impact, all of your bones shattering. When you think about it, SCP-073 is trapped in his own little timebomb hell. It's only a matter of time...
The recruitment of D-class typically comes from inmates, though under their security designation is this gem: "Condemned persons are preferred; in times of duress, Protocol 12 can be authorized, allowing recruitment of innocents or persons incarcerated for lesser crimes." The reader is then immediately reminded about how all D-class are killed off at the end of the month.
Protocol 12 is occasionally used in articles where a less than sentient, pliable/suggestible human is needed for an experiment, test or containment. Instead of taking Death Row prisoners they take people who are mentally ill.
While most (if not all) articles are built upon Fridge Horror, leaving far too many to list, there are a few good in-universe examples of this:
SCP-087, a never-ending staircase with an ominous white face that shows up just out of view. Only when you can't see it, it's right behind you.
It is, by all means, completely impossible to know just what SCP-055 is. Yes, it's hilarious when the researchers forget about things, but the horror sets in when you begin to imagine just what it could actually be.
Another dimension of horror arises when they list possible threats SCP-055 could pose, which is then followed by the line, "No action to counter any of these potential threats is suggested, or indeed theoretically possible." SCP-055 could potentially pose any threat right up to an "end-of-the-world scenario" and there'd be no way to know, and no way to stop it.
This is also why 055 is a Keter class, because they don't know how dangerous it might be. As far as they know, it's killed hundreds of personnel and they would have no idea that it's happened.
Of special horror are the black bars commonly used on the site - you don't know what's behind them, but there's a number of them left there for you to guess.SCP-231's age was originally "between ██ and ██ years of age," but after a user realized that meant she was at least a teenager, it was swiftly changed to "between █ and ██ years of age." Think about it.
When you go to the page for SCP-001 proposals, you receive a warning that, if you scroll down, you will be terminated by a visual memetic kill agent. So you scroll down, see a weird-looking picture, and nothing happens, giving you access to the proposals. Translation: the only thing preventing everyone from seeing SCP-001 doesn't work, leaving it open to everyone. And if something that important has been done badly, just what else have they screwed up?
At least it makes one of the proposals for SCP-001 seem less of a threat. Saying which one would spoil it, but if you've read it, you probably know which one. It's S. Andrew Swann's proposal, The Database.
SCP-1055 grows in size depending on how many people are aware of its existence. Naturally, they've taken some measures to keep its true nature under wraps, including tricking all agents into thinking that its "caretaker" is the SCP, and restricting access to its true nature on the site. Or at least, trying to; information which is supposed to be deleted can be read and seen by anyone. Just by reading the page, you are making the SCP a greater threat!
The interaction between SCP-682 and SCP-053 is real cute. But lets drop that Sugar Bowl for moment and think, 682 kills everything because they're disgusting, yet it became docile toward 053. And no, it isn't a case of Wouldn't Hurt a Child, it has killed at least two kids - quickily and messily. Remember that when humans make eye contact with or touch 053, or simply be near her long enough, they will go berserk and attack 053. Taking all those clues, you should have realized the wrongness hiding in 053.
Maybe 053 is for us what we are for 682.
The Ethics Committee. At first, it seems like a bad joke for an organizationliketheFoundation to have such a thing (hell, even the most of the staff think it's ineffectual and pointless), but the truth is they know everything the Foundation has ever done, is doing, and ever will do. Every thing behind those black bars, every [[REDACTED]] and [[DATA EXPUNGED]]? They know what's there. Procedure 110-Montauk? Yep, they know that, too. They designed it. The thing is, as bad as the Foundation is now, without them it would be much, much worse.
Ethics Committee Member: Remember this: the Foundation is not evil. We do not torture people "just because". We are against unnecessary cruelty. Which means somebody has to decide when cruelty is necessary. And that somebody is us... Stop trembling.
A lot of SCPs require sophisticated containment that would take a long time to construct. What did the Foundation do with the artifacts before their containment rooms were constructed? Even when the containment is simple they still need to locate a free room. Where did they put SCP 173 before they found it a cell? How was it contained and transported to the cell?
Consider this story, which goes into detail about the class A amnesiacs that are given out like candy after the more traumatic events. Now remember SCP-231-7 is given a class A amnesiac every few times 110-Montauk is administered...
The suggestion to nuke SCP-682 was rejected, because "if it survives and develops resistance to nukes, then we are totally screwed". But what's the point of avoiding the possibility of it developing resistance to nukes if you are not going to use them on it in the first place?
Because not only It Only Works Once, but also mutates in order to counteract/replicate said power. Generally, it prefers the former, especially if it took a lot of damage; in this case, if it doesn't do that then we would have a radioactive 682. This would be a major problem.
There are several other reasons as well. Nukes are not an easy thing to hide. Since only North Korea has even tested a Nuke in the last two decades, it would be very hard thing to explain away without risking the general public finding out about the Foundation. In the case there is a major containment breech on the site, a nuke is the last resort to prevent a Keter class from running away. You would hope that at the very least the nuke would hurt that lizard badly so it can be recaptured in that situation.
One tale, called "The Young Man" implies that 106 is actually a heavily mutated human...
It's even more implied that 106 wasn't actually a human to begin with, only that what happened to him made it worse
Another tale about 106 has him going on a bloody rampage on Halloween, with one unfortunate victim spending four days continuously running in 106's realm before the physical torture begins. Two bits of Fridge Horror emerge from this. One, the entire story takes place on the night of October 31st and the morning of November 1st, meaning that the time a victim spends in that hell is much longer than the time they're missing would indicate, and since 106 controls everything in its dimension, it can manipulate the flow of time however it likes. Two, humans cannot run for that amount of time, and would be near-death from thirst after four days in a waterless environment, meaning that the aforementioned control of everything extends to the biological workings of 106's captives. Combined with another captive somehow surviving horrifying injuries that should have killed him within minutes, this means that you can't die, or even pass out, unless 106 lets you.
SCP-331. Something about the entry is very sad and disturbing. It's a pet collar that turns any recently-dead cat into a zombie cat that answers to the name "Tumbles." The cat is friendly, but undead, and rots away eventually. What happened to the original Tumbles? Poor kitty...
SCP-1696 sounds innocent enough: a box capable of creating an entire universe on a small scale, with various physical constants set by the user. There's also a button that lets you start over with new parameters. But think about that: what happens to the people on that universe when the reset button is pushed?
On the Log of Anomalous Items, they list a fire alarm component that makes all who hear it barricade themselves in a room and refuse to leave. And they found it in a elementary school. Yeah...
SCP-1377. While "uncanny valley alien parliamentarians" sounds kind of silly, the thing you have to realize is that they're getting better at imitating humans every time. How long until we can't tell the difference?
SCP-203 is a human who had been unwillingly roboticised. Horrible enough in and of itself, but a particularly unsettling part would be this; a lot of his body parts have been removed and replaced with mechanical implants, except one, which was removed and never replaced. Said body part is censored with a [DATA EXPUNGED] block. Ouch.
SCP-056 takes on an appearance intended to make any observers envious, and it's theorized that its very existence depends on perception. Among the objects that its mimicked are couches and cameras. Even the ordinary furniture and equipment in SCP Headquarters is sentient.
Not quite. SCP-056 changes its appearance to make the viewer envious, right? So the SCP Foundation thinks, "Well, what if we just set up cameras and have nobody watch it for a while?". SCP-056 is smarter than that however, so it just takes the form of the camera doing the "watching". How does it know what the camera looks like? It most likely has some degree of psychic ability; maybe it's even clairvoyant.
SCP-1926. "Meet the Mewts"... this rather ordinary SCP report takes a total turn to creepy when you reach the very last line and start to piece together the string of events that most likely led to their current situation.
SCP-1442 is a sentient corporation that, instead of having a sinister motive, just wants some companionship from another corporation. That takes some of the edge off, but when you really think about it, something that deals in "advanced defense technology and [REDACTED]" can't be all that harmless.
The existence of SCP objects themselves. Reading through the SCP database, which intentionally analyses SCP and their effects through cold, dry, clinical precision of science, you start noticing classification of SCP as somehow contrary to the natural universal and laws of physics. Then it hits you: They aren't. Most of the SCP objects, even the ones that are blatantly using some form of magic or extra dimensional wedgies to perform their functions do so without fundamentally causing the universe around them to break, therefore doesn't it makes sense that however improbable, however horrifying that the existence of SCP objects and the forces capable of creating them are not only possible but normal in the grand scheme of things. SCP objects will never stop being discovered or created, they are as natural a facet of the universe as the laws of thermodynamics they defy in the first place.
In this diary entry, we see that SCP-1048 only converted the girl's parents (the mother's unborn child and the father, technically, but the mother still died from it) after they saw it and presumably tried to get rid of it. Yet it acted like a whimsical living toy with the daughter, to the point where at the end, she was happy to live on her own with it while it brought her food. Then you have to wonder, did it need the daughter for some reason? And why turn the parents into more teddy bears? Maybe to help keep the daughter around? Now, remember that SP-1048 is doing the same thing in the Foundation, except here we have no clue what triggered its decision to start making more of itself. And because the Foundation is so massive, it could theoretically have as many people around as it wants, for whatever it needs them for. Good thing there's only one of it - Oh Crap, actually the Foundation has no clue where it is, and it can make as many copies of itself as it needs, at this point. Uh oh...
7 seals. 6 broken. SCP-231-7 is (or isn't) the last seal stopping SCP-2317 from coming into our universe. Procedure 110-Montauk is fully justified.
Speaking of 2317, it's revealed in the final iteration that the containment is all useless and is just there to hide the fact that the O5's have no idea what to do. Who knows what other containment procedures are also a sham.
Y'all know Gustave? That infamous crocodile from Africa? The one that killed around 300 people, some of which wasn't for food but just for the sake of killing? Also, that he has survived gunshots and even a grenade? Consider the following, then. What else do we know that is large, reptilian, hard to kill, and kills for no reason other than sheer malice? SCP-682. Coincidence? Or could it be possible they are one and the same?
682 is known to be sentient and capable of talking, so not likely. Also, the photo on the site doesn't look crocodilian at all.
Fun fact: that picture is actually of a dead and heavily decayed whale.
In SCP-1678 : One of the random messages playing in the city says ĎCanít make ends meet? Do not be ashamed. Brysonís Home for the Poor is here to help.í When you read the description of the "Bobbies" they are thought to originate from said home because they are all wearing inmate style jumpsuits from said building. Here's a description of the Bobbies: "these entities are constructed out of human corpses crudely dismembered at the head, wrists, knees and elbows and re-assembled using simple industrial hinges and screws. The head is always wrapped in bandages."
