SCP Foundation/WMG

SCP-882 is the heart of god from The God And World and SCP-835 is The God Of Flesh it fought with.
The Church of the Broken God want to bring back the Gear God and will try to destroy any other SC Ps that correspond to the other areas in the story.

TV Tropes is the real SCP Foundation.
The SCP Foundation website is a cover-up.
 * Alternatively, rather than merely being a recruiting tool for Red Shirts, we deal with keeping all the nasty memetic stuff contained and--Oh Crap! Bond Villain Stupidity is loose! How could we have left all the necessary information on how to escape just lying around?!
 * Nah, the real big jobs go to the Public Library system, Tesladyne, and the BPRD. We just catch what gets through. The SCP Foundation is a red herring.

Dr. Clef isn't just lying about himself, he's lying about everything.
None of his adventures that he writes about are in any way true at all.
 * This story implies that all his adventures are due to a corruption of an ordinary scientist's records by the fan-fic plague
 * Well, it implies that his differing origin stories are caused by SCP-732, but as for his exploits at the Foundation, Clef doesn't write all of those pages himself, and cross-checks by more reliable authors' pages seem to check out stuff that isn't explicitly stated otherwise.

The SCP Wiki is part of a cover-up
The REAL SCP Foundation publicizes some of its most leak-prone materials through the site so that if the documents actually are linked they'll get traced back to the wiki and written off as a boring 4chan micro-fiction project.
 * That's not a Wild Mass Guess, that's explicitly stated repeatedly.
 * You realize, of course, this implies that the REAL Foundation is covering up shit that's so dangerous, their willing to let information about SCP-682 get out because it's not as bad by comparison?
 * Rather, SCP-682 is one of the most likely of the SC Ps to be heard about. Anybody who claims that a disaster was caused by 682's escape will be ignored as a nutcase who reads too much internet.
 * No. That's not the horrifying part. They're covering up shit that's so dangerous that they're willing to fully disclose SCP-835.

Dr. Palmer doesn't really exist.
Nothing I can find proves her existence, just a handful of namedrop moments... no profile page, no photography, nothing.
 * That's because (with a few rare exceptions) only actual site members are more than namedrops.

SCP-914 and SCP-882 are infused with the substance extracted by SCP-158
It makes sense.

SCP-001 is something that acts like a sociopathic MIB agency.
One that can hold a violent, indestructible reptile, several angels, several gods, at least two Gods, a number of eldritch abominations, and a number of locations that sometimes can't even be kept track of by their very nature. All this while having  and maintaining The Masquerade. The reluctance of the Tribunal to make a final decision on classifying SCP-001 is to hide that SCP-001 is really the [REDACTED] and chronologically first to be catalogued by nature of being the catalogue itself.
 * Perhaps the foundation itself is a memetic hazard. The reason 001 has multiple proposals is because the parts of all members (Even Clef) that has yet to be infected is trying to express itself. And the reason they crack down on other memetic hazards is because the foundation doesn't want competition.
 * Wrong. The REAL SCP-001 is.

SCP-239 never believed what the Foundation told her.
They told her she was a witch, and they were an order of magic users. She alters reality to how she thinks it is. So if she really believed them, why hasn't reality changed to match?
 * Her powers were stated to be localized or What she can see, she can change

SCP-610 is BLACKLIGHT.

 * The infected are hive-minded, and seek to mindlessly infect everyone else.
 * Both can deform an infected person.
 * Both can infect non-organic structures, and have done so on a wide scale.
 * Both are predominantly a sickly red in color.
 * Both are being combated by a secret agency.
 * Both cause zombies and special types of zombies.

The SCP Foundation is a front organization... for the exact same organization

 * Something this bizarre appearing on the internet is bound to be dismissed, at first, as fiction
 * Although there will be counter arguments that it's all true
 * The debate and conflicting views, while drawing attention, don't actually draw attention to the SC Ps or organization itself, just to those involved in the debate. The conspiracists, weirdos, skewed people, cynics, pseudo-cynics who don't actually know, people arguing one side over the other. And not any of the important stuff. These just mark it as another "thing off the internet" and not of any great concern...
 * And what better way to mask the Foundation, than by not trying to hide it? After all, anything that looks even vaguely like a cover up will be subject to wild and bizarre theories and possibly the truth.
 * So you don't cover it up at all, allowing the Foundation to be easily hidden by the smoke of the internet
 * And a second layer, by having someone explain this, as yet another crazy theory
 * and so on...
 * ...and so on...

Theta Prime isn't a number
Although dangerous it is possible to store Theta Prime electronically, given the fact that computers are designed using are "flawed" mathematics any attempt to store it electronically would have to store the symbol used to represent it, rather then the numerical value itself. Thus Theta Prime's unusually properties are a result of the symbol used to represent it. The formula the proves Theta Prime's existence as a number is flawed, but the symbol for Theta Prime, hypnotizes anyone who sees it into being unable to find fault in that formula or any other that supposedly proves it existence as a number.
 * Except that the symbol for Theta Prime is Exactly What It Says On the Tin: the Greek let theta with a [[http://en.wikipedia.org/wiki/Prime_

Theta Prime is the result of pi being broken
The Rules of The Internet clearly state: "Any breaking of pi will result in pi being broken. No one knows the consequences. You have been warned." Chuck Norris roundhouse kicked pi, and now here we are.

Theta Prime is a number from another dimension
We didn't miss a number. A number was added, from some other universe, and it integrates itself into anything it can break by screwing up the number system that thing works off of.

529's hindquarters exist
They are merely not attached to the front half, and are wandering around somewhere.
 * Dirk Gently was looking for them in The Salmon of Doubt.
 * They found them in SCP-004.

If the "Global Occult Coalition" Wiki is successful, "The Church of the Broken God" and "Marshall, Carter, and Dark, Ltd." will also gain wikis.

 * I can just imagine how the sites would look: CBG's site would be full of various "relics" and "lore", similar to SCP foundation, but with a pseudo-religious Path of Inspiration feel to it, and some sort of Metaplot. The MCD wiki, on the other hand, would be a virtual catalog supernatural artifacts, with "Customer Reviews" detailing objects... "issues"...
 * Not exactly confirmed, but "The Serpent's Hand" got a wiki, so it seems plausible.
 * Here's Marshall, Carter & Dark's catalog.

The reason 076-2 regenerates and kills is because of his past with 073.
I mean, they're Cain and Abel, and everybody knows it. Abel wasn't originally an implacable death-dealer; he was just a shepherd (hence his innate skill in cattle farming). Because of the nature of his original death, though, and his being favored by 343 (076 is a Marty Stu because the biblical Abel was also), he was resurrected with a unending thirst for vengeance. Also, if 073 ever kills 076 again without doing so via his curse, Abel will stay dead.

914 is from 682's home dimension.
There seems to be some sort of sentient force behind the machine. However, it has been determined that the machine itself isn't sentient. This implies that the objects placed into 914 are sent somewhere, where they are modified and returned. If this was 682's world, it would explain the obsession with it.

The only thing SCP-028 can't tell you is how to destroy SCP-682.
Due to Murphy's Law.

SCP-107-J is Bananaphone
Remember the animation that made it a meme for a while? It played in a guys head until he went practically comatose and died, and then one of the other guys in the animation started hearing it. SCP-107 is a bit more extreme, but it's otherwise quite similar...
 * Congratulations, you found the joke.

SCP-447 created SCP-682 from a dead body.
It would explain why the SCP Foundation is extremely averse to SCP-447 being near a dead body.

SCP-447 created SCP-173 from a dead body.
It explains itself.

SCP-239 is SCP-343's daughter
They're part of the Holy Trinity - 343 is the "Father" and 239 is the "Son". Mr.Deeds is a Holy Spirit - when he was trapped in SCP-662, the Trinity got separated. Most of God's power has been divided between Father and Son aspects. Mr. Deeds has much more limited power, but also seems far more reasonable and knows much more that 343 or 239, so he might inhibited most of God's infinite wisdom, but can use it only to answer questions he has been asked. The Son absorbed all feminine aspects of God, thus explaining why his form is of a little girl. 239 doesn't remember being a part of Holy Trinity, neither does Mr. Deeds. 343 remembers being God and creating the Universe, but he doesn't remember separation and thinks he's whole, that's why he doesn't try to reunite with either 239 or Mr. Deeds.

Following above theory, SCP-682 is an anomaly created by separation of Holy Trinity
That's why 343 cannot see it and claims he didn't create it. 682's existence is possible by God's absence and it cannot die as long as the Trinity is broken. Once 343, 239 and Mr. Deeds unite again, the first thing reborn God will do is to destroy 682.

SCP-447 was somehow created from dead bodies
The evidence? When a corpse was run through SCP-914, the result was noted as being very similar to SCP-447...
 * Not just similar; it was identical.
 * Not only that, but SCP-447-2 run through the "Rough" setting produced a human corpse that [DATA EXPUNGED].

Dr. Clef is Satan and also one of SCP-166's parents.
Specifically, he's the "elder being of great power" named as 166's father when she was left at the church. This would explain his immunity to her attracts-all-men thing, her immunity to his disgusts-all-women thing, and (depending on which version of Satan you use as a base) possibly also SCP-166's extreme piety.

When SCP-447 comes into contact with dead bodies, it creates
All the evidence is there; look at the final log for SCP-093 and 914's experiment log.
 * This turns 447 from funny to pants-shitting.

SCP-231's [DATA EXPUNGED] is another
The Montauk Monster was a corpse that washed up on a beach that looks like a monster. The picture of is of a similar oddity. The procedure to eliminate SCP-231's [DATA EXPUNGED] is called 110-Montauk. Everyone at SCP is terrified of. If she's going to give birth to one, it makes sense that they'd go to ridiculous, hideous lengths to prevent it.
 * Or, was the child of SCP-231-6, with the first 5 being weaker versions that the foundation eventually managed to destroy, which explains even better why they'd go to such lengths to make sure SCP-231-7 never gives birth.
 * I don't know, the sexual motif for 231's story wouldn't seem to fit with something which hates all biology. Then again, maybe that's why it hates all biology.
 * I like this version better. is more or less safely contained, despite being apparently indestructible, very powerful, and possessed of an infinite appetite for the destruction of Earthly life. Despite frequent breaches of containment, the Foundation always manages to subdue and retrieve it, which would be somewhat at odds with the idea that having a second  around equals The End of the World As We Know It. Hell, they've already dealt with having two of it at the same time.

SCP-682 is actually a retarded form of its species.
Imagine. Even slightly dumber or weaker or less superadapting than the rest of its kind. And now think how hard it is for the Foundation to keep it under control, and what might have happened if, say, a normal specimen was out in the world...
 * Maybe it's a baby one and is just cranky because it wants its mother.

The last SCP-404 log with the dead D-class was about SCP-053.
The number is blacked out and the strongest implications are probably that it was SCP-231, but think about it. 053 induces uncontrollable rage in adult humans, and that's precisely what happened with the final picture. Perhaps the final picture was 053 having a Glamour Failure and she actually looks like something as horrifying to humans as humans are to SCP-682 ...

Someone in the Foundation is named Fred.
When SCP-423 was exposed to a hard copy of its own experiment log, it briefly created an endless Recursive Reality. A similar experiment was run using SCP-826 and gave the same result. This raised the possibility that the SCP Foundation and the world around it may already exist within some kind of printed document. Since then, guest researcher Fred has become the target of many suspicions.

The reason you can't see 055 is because it's an Eldritch Abomination.
Think about it. Maybe the reason you can't see it is because You Cannot Grasp the True Form of it. It's so horrible, so awful, so downright terrifying that your mind instantly erases it form memory.
 * That makes waaay too much damn sense,
 * And is also kind of supported by one story where a D class walks into SCP-028 and starts screaming about an unstoppable destructive force, "At Site 19… number Fift…" before forgetting everything he was saying...

Warren Ellis is a member of SCP Foundation
C'mon, some of their SCPs looks like something he could pull out.

The reason you can't see 055 is because it's Milhouse.
Because Milhouse is not a meme. (Sorry.)
 * Wait, since when is there a 055?

SCP-231-7 is not an SCP, nor will it ever give birth to one.
There are no SCP-231-1 through SCP-231-6. The SCP Foundation made up that story. What is SCP-231-7, really? She's just some little girl that the Foundation was able to kidnap. They now use her to do psych evaluations for the squicky stuff that DOES have to be done; to make sure that the D-Class really is willing to do anything. Further, as she ages at a normal rate, there is a continuous rotation—when the current SCP-231-7 gets too old to invoke the intended psychological effect, they terminate her and get a new one.
 * Surely there are infinitely less convoluted and expensive ways to test that? The Foundation have enough problems getting hold of enough D-class as it is, and since they have to put potential workers through a round of psychological tests before even letting them know 231 exists, this theory strikes me as a bit wasteful of time and money.
 * Someone in Something Awful's SCP thread found a comment that said there is no 231: the whole story is just a Secret Test of Character to prepare potential researchers for the terrible things they'll have to do to in order to protect the world and if they can't handle it "a very bored guard with a gun" can take care of them. It can't be proved either way thanks to the magic of No Continuity.

The universe is expanding because SCP-184 is not contained in an object.
Which also means new and increasingly... off universes are being continually created by the thing. It may be better to contain it in a cardboard box.

The creature 231-7 would give birth to is the
We have a girl pregnant with an Eldritch Abomination that would destroy the world. We have an Eldritch Abomination that destroyed a world. Do the math.

The band Anal Cunt has encountered SCP-230 before.
If this is true, that encounter would have been the inspiration for this song.

Now, if we find out Anal Cunt is hiding a time machine, we'd have to check to see if they actually went back in time and voted for Hitler.

SCP-682 was once human
He somehow gained access to the ability to self-modify, and decided he really, really didn't like human existence.

SCP-682 and SCP-343 are Eldritch Abominations with respect to each other.
From 343's viewpoint: 682 is so alien that he can't sense it at all, and he knows he never created anything like that. 682: When they tried using SCP-536 to dispatch 682 (536 creates localized alterations of cosmic constants like strong nuclear force and speed of light--a pocket Eldritch Location, essentially), not only did it not work, despite successfully dispatching tissue samples, it seemed like 682 was enjoying it. Never mind Earthly life forms--our cosmos is an Eldritch Location to it. So guess how it views the creator of such a dominion...or would view...

SCP and GOC are actually headed by the same person/people.
While the obviously sane thing to do is have one organization dedicated to preserving certain artifacts and destroying others, you run into the problem of people who are variously concerned only with preservation or destruction, not both. Solution: Create one organization for each in order to streamline the preservation and destruction, and get those only-interested-in-one-aspect candidates. Create a fiction of independent existence and rivalry for further catalyzing. If you're nefarious enough (like certain rumors about Clef indicate), you can even use the GOC to further world conquest goals by tricking them into thinking certain artifacts are too dangerous to humanity to exist...and thus have them destroy things whose very existence made your conquest more difficult...

Exposing 447 to dead bodies...
...Causes the bodies to reanimate. And sing show tunes. Really bad show tunes.
 * Now, is that really a terrible enough scenario that faking contact will cause O5 personnel to shit their pants with fear? (See the list of Things Dr Bright Is No Longer Allowed To Do.)
 * I think you're underestimating just how bad these show tunes really are. Have you ever heard "Over the Rainbow" sung a cappella by a bunch of people with, at best, half their vocal chords intact? And never stopping?

SCP-272 is the key to killing SCP-682
It's probably greatest tool for inflicting vigorous amounts of physical trauma at astronomic speed ever conceived; it's just a matter of getting a fast moving and/or powerful enough light source to maximize the distance between the thing we want to kill and its shadow. We could probably create a light strong enough to pin its shadow to the moon, for starters. And it'd be interesting to see how this tremendous intellect reacts to the insanity effect if it can be pinned in place for three days, which in its regular sedated state doesn't seem unlikely. ..

106 and 035 are connected
Think about it. They both secrete corrosive fluid, the both torture for fun (albeit in different ways) and they both poses space warping abilities. if that was not enough, 035 host degrades physically but continues to function. 106 is in an advanced state of decay but still functions.

682 is female.
053's picture with the Desire Camera showed her playing with 682, with the monster wearing a frilly dress. If anyone's equipped to identify whether 682 is female or not, it's probably 053. This leaves open the horrible possibility that it may breed.

231-7 knows damn well what she's carrying, and was in on the cultists' plan.
Well, you can tell yourself that so you can sleep at night ... But it is within the realms of possibility, considering the Foundation has already encountered cases of the Enfant Terrible. Even if she wasn't keen to actually release it on the world before, she probably is now. Wouldn't you be?

Procedure 110-Montauk is tickles!
They expunged the data so the ridicule of the situation would have as little exposure as possible.

Procedure 110-Montauk isn't done to SCP-231-7.
It's done to the extracted fetus: Possibly the only thing worse than everything implied by 110-Montauk is being forced to watch it happen to your own offspring as you're restrained to the bed. Then after they're done having their way with it they force SCP-231-7 to administer a Mercy Kill.

231 is actually contained within a main SCP site.
The convoluted method of getting there is just a red herring.

557 originally contained 682.
Mention is made of the "bastard son of Apep"; Apep was a serpent god, and the reptile theme would fit.
 * Based on some old discussions, that was originally going to be outright implied. But they're not too fond of cross-referencing.

582 is Slender Man's hobo brother.
He does pretty much what Slender Man does (such as existing because "fiction" about him exists), but doesn't seem to be as "well-dressed."

Dr. King has witnessed the effects of an apple from 891.
After that sort of experience, I'd be terrified of appleseeds (and anything else apple-related) too.

SCP-682 can only be destroyed by something we would regard as utterly harmless
Because they'd never think of that at the SCP Foundation.
 * Maybe if it touches the highly-vulnerable anteater they'll cancel each other out.

Diamanda Hagan went mad from watching SCP-993 as a child
The demented clown make-up, the crazed behavior, the cursing... it all fits.
 * Can we also say the same for Insane Clown Posse?

SCP-321 is Bright's sibling, too.
In page comments, Dr Bright (the writer) said that in his personal canon, Jack Bright has an older brother, Mikell (aka "05-6" aka "Agent Cowboy"), and a younger brother, TJ (aka SCP-590). In the Foundation Tale titled We're Off To Be The Lizard, Dr. Bright (the character) confirms having a sister named "Claire Pierce." One of Dr Bright's entries in the Wanderer's Library, The Tale Of The Brothers, details three brothers and two sisters as descendants of the Prophet. The three brothers are clearly Mikell, Jack, and TJ, and the "other [sister] who runs from her blood" must be Claire, as the first sister is said to have been stillborn. In Bright's SCP-001 Proposal, 05-1 refers to Jack's father as "Adam." 321 is female. Her parents are named Adam and Evelyn in 321's report, which Dr Bright also authored. Both of these Adams were 05's. (Admittedly, the Adam from 321's page worked his way up to 05 status from Junior Researcher, while the Adam from the 001 proposal was a founding member, and thus was an original 05. Also, 321-Adam's last name has only five letters, and could not be "Bright" as 001-Adam's was.)
 * In the Active Duty logs, this is proven to be true.

In Procedure 110-Montauk, they force SCP-231-7 to watch cheesy movies. The worst they can find...
...But unlike Mike and Joel, she doesn't have any robot friends to help keep her sanity.

The entity within SPC-911 is the mind of the Broken God.
It wants to merge with at least two other SCPs, which is also what its Church seeks.

The entity in SCP-1315 Level 18 is functionally identical to 173
"This challenge is easier for two players than for a single player", because one can blink while the other looks.

If/When the site ever makes it that far, SCP-4869 will be a supernaturally clever ace detective.
It wouldn't be the first time the foundation had used thematically appropriate numbers.

SCP 073-2 is Enkidu
First of, it's Able, not Abel. SCP 073-2 is a humanoid-but not actual human from the Middle East from the dawn of human civilisation, whose native anguage seems a very anncient Sumerian. It is superhuman, i.e. about equal to Gilgamesh. His favorite work is the Epic of Gilgamesh. And he is very good in animal husbandry.

SCP-053 and SCP-682 are from the same reality/dimension
In fact, they're the same species. And SCP-682's in love.

SCP-980 was once human.
"SCP-980 was found at the █████ █████ apartment complex in ████████, ██, after several hours of exposure to SCP-980 caused deaths and mental harm to nearby civilians as well as color and shape simplification to said apartment complex and many objects inside. At the time of acquisition, it was wearing heavy winter clothing and a hood. SCP-980 has not responded thus far to inquiries as to how it came to be, though room 307 seemed to have been affected more than other nearby locations. In addition, the tenant of room 307, ████ ██████, was unaccounted for among the bodies of SCP-980's "victims"."

SCP-674 does work, just in an alternate universe.
The SCP also causes the user to see the TV broadcasts from the universe he's slowly depopulating of major political figures.

SCP-557 was the first incarnation of the SCP Foundation.
It was "an ancient prison and containment site" for heretics, sorcerers and the abnormal. Sound familiar? And then there's what could very well have been SCP-682 formerly locked up in the deepest, most secure part.

SCP-682 is Ammit
For those who don't know, Ammit was a demon who had the head of a crocodile, body of a lion, and hindquarters of a hippopotamus. In Egyptian mythology, every person would undergo a trial before he or she could pass onto the afterlife, often by weighing their hearts on the Scales of Ma'et, the personification of order. If the heart was heavy with sin, then the person would be devoured by Ammit and refused entry. So how does this apply to 682?

Ammit has the face to qualify as a "vaguely reptile-like creature," and the lion part of her would provide the mane that is present on the photo (and most artistic renditions) of 682. Moreover, she pretty much kills everyone who's deemed unworthy. SCP-682 is so violent because it in turn deems everyone in the world as "disgusting" and horrifyingly wrong. Therefore, it can be concluded that 682 is Ammit forcefully brought to our world. By seeing and judging us all by the scales of Ma'et, it deems us all as unworthy and attempts to kill us as a result.

Based on 682's attitude, we can also safely conclude that no Egyptian actually passed the trial.

SCP-024 is the eerily, cheery Announcer from Silent Hill

 * Compare and contrast the article on SCP-024, with the scenes of the Announcer in Silent Hill youtube videos. They're too similar to just be a coincidence.

The Foundation is set in 21st Century Warhammer 40,000 universe.
The sheer number of alien artifacts and objects that can corrupt or kill humans with absolute ease is a clear sign of Chaos. The Foundation itself is the precursor to the Inquisition.
 * The second suggestion really needs to be expanded on. Kudos to the particular troper who wrote that, as the SCP foundation, in many ways, is ALMOST IDENTICAL to the Inquisition.
 * 1) The Foundation, like the Inquisition, has almost unlimited resources for whatever purposes it deems necessary, to the point of being able to fend off entire countries (just like how the Inquisition can order around pretty much anyone in the Imperium.)
 * 2) The Foundation, like the Inquisition, deals in a massive number of both xeno and supernatural artifacts, many of which could easily be classified as Chaos artifacts (quite obvious, really.) In both cases, the organizations attempt to study, classify, and (if necessary) destroy said objects/entities.
 * 3) Both organizations have almost no regard for human life whatsoever (The Foundation goes through D-class workers like toilet paper, and we all know how much Exterminatus is loved by the Inquisition....)
 * 4) Both organizations are notable for bring staffed and run by people of rather dubious moral fiber and mental stability.
 * 5) Both organizations answer to no one (it's unclear in the case of the Foundation, however.)
 * 6) Both organizations are more or less essential to the survival of the human race.
 * So Captain Dmitri Arkadeyevich Strelnikov is a Space Marine in disguise then?
 * Nah, he's a Vostroyan.

The Archaic from Penumbra is, or is a branch of, the SCP Foundation.
"Geological structure of the earth beneath Greenland, including several unknown caves and [EXPUNGED]." Penumbra takes place in the Archaic facility located beneath Greenland.
 * The immediately obvious evidence: the cheerful disregard for human life, being devoted to containing and learning, and having great influence. However, the real zinger may be found in the article for SCP-028.

The real leader of the SCP is GLaDOS
This is what she meant when she informed Chell that she was the only one standing between "Us... and them".
 * Also, she filed herself under the "Joke" SCPs to throw us off-guard.
 * Link or it didn't happen
 * Maybe it is already contained, some of the digitalistic SC Ps have their own mind.
 * Glados could also be Nala, the AI used to control SCP IRC.

G-man plays the SCP Foundation off for amusement, and to keep himself aware of potential "employees".
A potentially god-like being who can warp time, space, reality, and all kinds of other stuff anywhere, anytime, for his own needs would defiantly enjoy hand-picking expert agents for his goals.
 * Alternatively, G-man is F0O.
 * Fishmonger is too fat and speaks with a normal accent.

SCP-682 is Envy.
Somehow.
 * They can both regenerate almost indefinitely. Are nigh invulnerable. Can shape-shift, or adapt and evolve in 682's case.
 * Have superhuman strength and both have a disdain for all of humanity and life in general.
 * Hohenheim and SCP-343 AKA God both call them abominations.

SCP-231-7 is Alma.

 * She's locked away in a facility and is rather important.
 * She appears to be a young girl.
 * Her giving birth = The world is FUCKED.
 * Her exact age is never explicitly specified - maybe because they don't know how old she really is.

No More Heroes is set on a SCP site
Not only that, but the SCP foundation is killing two birds with one massive stone by letting reality warpers kill each other for fake ranking and using money!


 * Dr. Naomi seems to be a researcher living on-site and helping circulate an economy for a site the size of Santa Destroy. Refurbishing beam katanas sounds like a good hobby to be doing to maintain the status quo.
 * Dr. Naomi does look oddly worried when she receives military documents from Travis...
 * Why are the assassins crazy-awesome? Because they are crazy reality warpers. I am not sure about Doctor Peace, though. If he's just dealing with this bloodlust, then that would make sense.

The SCP Foundation is SEELE or will become SEELE
According to what may or may not be Word of God, SEELE originally was an organization that collected religious and paranormal artifacts under various guises and fronts; upon discovering the Dead Sea Scrolls, they turned into the SEELE we all know and love.

Sometime in the future, the SCP Foundation will find some very interesting SCP objects, including a set of ancient documents and two massive underground spherical constructs, each containing two similar godlike-but-inert beings, each impaled with a giant spear.

Plus, just look at Dr Clef's proposal, what if the man who received the command of "PREPARE" was none other than Keel Lorentz?
 * You know, when I watched NGE for the first time, all I could think of when they mentioned the SEELE committee was 'hey, that's exactly like the O5 overseers'. Also, a crossover between the SCP Foundation and NGE would be awesome in about three hundred different ways. Too many things just fit so well. * mental image of SCP-682 fighting Unit-01*

The SCP Foundation is an offshoot of the Gunnerkrigg Court.
The Court has been originally founded as a place to research the "etheric" - that is, the supernatural. Soon after its founding, a group within the Court decided they were unhappy with the way GC was functioning, and left the Court to create their own organization, to research the supernatural in their own way.

Both the GC and the SCP Foundation seek to hide their exact beginnings. There is still a feud between the two - that's why they dislike to talk about the other's existence.
 * Also: SCP-001 is, in fact, the Seed Bismuth.
 * The Foundation cut ties with the Court (or vise-versa) because the Court's containment procedures (as far as we've seen and compared to the Foundation's) are horrible: The Court allows humanoid SCPs to interact with "normal" people and even employ a few SCPs to instruct other SCPs on how to control or even enhance their powers; creature and object SCPs are either poorly contained or not contained at all.

The SCP Foundation is a front for the Warehouse.
Both organizations deal with Artifacts Of Doom, try to keep them out of public knowledge, and are highly secretive. The wiki is made so Warehouse agents can find out about possible Artifacts and retrieve them.
 * Alternatively, Warehouse 13 is an SCP Foundation storage facility, for the same reasons listed above.
 * This second WMG sounds even more plausible when you realize that the Foundation wiki(s) has been around longer then the Warehouse show has been on the air.
 * In-universe, however, the Warehouse(s) has(have?) been around longer than the Foundation. The Warehouse has been known to always be based in the most powerful nation in the world. In fact, the first Warehouse was the Library of Alexandria. If the Joke SCPs are considered "canon", then this one hints that the Foundation was created after the invention of elevator cars (seeing as the one that kicked off the founding of the Foundation was discovered in one).

SCP-708 is a primitive Lagann.
It feeds on enthusiasm. What more do you want?!

Theta Prime is Missingno.
It's a missing number. It can't be contained in a PC. It causes whatever system it's being contained in to slowly breakdown and eventually become completely useless.
 * Yep.
 * Then what does that make 106?
 * Hitmonlee?

SCP-682 is Ridley.
It's a big reptilian creature that seems to hate all Earth life. It can adapt and mutate, and it just won't stay dead no matter how many ways you kill it. It's also extremely intelligent, despite appearances.

SCP-096 is a TAAAAANK
It goes berserk on people, is rather hard to kill, and has grotesquely non-muscled arms.

SCP-578 is Alma too.

 * First form is dressed, while more elegantly than Alma, is still in a dressed. Around seven, and while can be harmed, causes strange phenomena.
 * Second and Third forums are her naked and emaciated, thought the third appears to take on a healthier form eventually (note her forms in FEAR 2).

SCP-719, 720 and 721 are all pieces of Eden.

 * Presumably early prototypes of what  constructed which run off some sort of circuit switch involved with some sort of chemical in human blood.

SCP-231 is Miss Lucy.
Makes sense to me. The [Data Expunged] is/are her "leeches".

The Children of the Scarlet King are Gropagas.
"Scarlet King" refers to the colour of the CAPTCHA Inglip uses to communicate with its followers.
 * ...Fuck. me. That's...that's why he killed it. He was either momentarily lost to madness or previously unaware of the nature of humans and he realized what the result would be. The last part is because he had to in order to prevent the end-time.

SCP-239 is Haruhi.
Seriously, this should be obvious.

682 is an adult form of The Monster in the Darkness.
The Monster's either gotten sufficiently used to organic beings to get along with them, or is simply too young to realise that they should be scary to it (it's heavily implied in OOTS that the Monster is a juvenile, whatever it is). Though if there is a juvenile 682 out there, that implies there are several of it around. Eek.

682 is a mutant form of the tarrasque.
Unlike the original, it can speak and seems actively evil rather than True Neutral.
 * Someone find a saint to becalm it, then, just like the original from French lore.
 * It's definitely some kin, at any rate.

SCP-055 is an imprisoned Silent.
This would explain everything about SCP-055. Interestingly enough, this doubles as an inferred Crowning Moment of Awesome for the SCP Foundation, since they somehow managed to imprison one without any memory of it and (since Silents seem to be more powerful in this universe) without access to any written records of it.

055 is a pumpkin
What pumpkin?

SCP-055 is Canada
Who?

SCP-055 is Ann
Her?

682 is related to The Thing Hiding Under Your Stairs.
C'mon, tell me the skull shape doesn't look the same.

682 is a Spawn of Rovagug.
Think of it: Aside from the whole "sapience and implacable hatred" part, its description (as previously noted) makes it sound a helluva lot like the Tarrasque. (Well, most of the time, anyway.)

SCP-682 is Discord.
It's a malevolent, chaotic being which kinda looks like a lizard (or at least like some quadruped), though it looks like he's lost its Reality Warper powers and can only apply them to himself. Looks like Celestia decided that banishment to another universe will be the surest form of containment. Sounds like a stretch? The story Letter of the Day" is quite an argument for this theory.

SCP-682 is The Winslow.
It's a four-legged reptile; it's indestructible -- as far as anyone can tell; it's talking, but not very smart -- as far as anyone can tell; it's on Earth and in humans' possession, but has no apparent good reason to be here. They just got the poor croc already pissed off and kept him in murderous mood with their tests. Also, once you saw this WMG, you can't unsee it.

SCP-053 and SCP-682 are alternate dimension counterpart to Saya and Fuminori.
Now that 682 found the only "beauty" in this world, it will also try to rescue her once escape its confinement.

The Foundation is our universe's equivalent of the Torchwood Institute.
It's outside the government, beyond the police, and has seemingly infinite assets and resources at its disposal. The point of divergence is that, in our universe, the Foundation is competent at its job, is not responsible for creating most of the paranormal entities it must contain, and does not try to contain any potential difficulty by sending John Barrowman to seduce it.

The Foundation is in charge of the organization pulling the strings in The Cabin in The Woods
Major film spoilers ahead!
 * Or, in addition to that, whatever SCP-231-7 is carrying is

SCP-682 is Doomsday
It's both hard to kill and grows stronger from it's injuries.

SCP-076-2 is not really Able, or a video game character, but a Toon
Specifically, he's the true form of Judge Doom. Think about it; both of them are immensely powerful, Axe Crazy, can shrug off all bodily injuries, spawn any assortment of weapons, and are more than happy to murder people on a grand scale For the Evulz. The problem, though, is that the Foundation is unaware of 076's toon nature and hasn't figured that all they need to do to kill him is to throw a proper mixute of benzene, acetone, and turpentine on him.

You can usually find SCP-1106 for sale at Sears
...And sometimes, K-Mart has a Blue Light special going for a similar product that's almost as good and a lot cheaper!
