History SCPFoundation / TropesSToZ

** [[invoked]] [[https://scp-wiki.wikidot.com/scp-1440 SCP-1440]], a man who destroys man-made objects [[spoiler: because he pissed off the Three Brothers of Death so badly they wanted to torture him forever by making him the ruin the human world he tried to save with the three death-defying objects he won from them (he initially just wanted a second chance at life but when he won he decided to ''[[WhatAnIdiot humiliate death]]'').]]

* SleepWalking: [[https://scp-wiki.wikidot.com/scp-5586 SCP-5586]], a sleepwalker who has been known to turn up in a variety of odd locations, including the Queen's bedroom, the Oval Office (where he threw his slipper at President Nixon), and the ''surface of the Moon''.

* ThingsThatGoBumpInTheNight: The mythical Voice-Taker, described in [[https://scp-wiki.wikidot.com/scp-5768 SCP-5768]] is inspired by various real-world boogeyman legends of monstrous figures that punish naughty children. In this case, it's the ghost of a man born with a mouth two sizes too big who was robbed of his own ability to speak, and now steals the voices of children who lie, swear, and are rude to their elders. Also possesses a WeirdBeard made out of flies and maggots.

* WickedWitch: [[https://scp-wiki.wikidot.com/scp-5294 SCP-5294]], an entity physically resembling an old woman, with a long tail similar to that of a rat's, which ends in a large eyeball. Considering she used this tail to steal and cook young babies in their homes back in the nineteenth century, it's safe to say she's as wicked as they come.

** An addendum to [[http://www.scp-wiki.net/scp-239 SCP-239]], an eight-year-old RealityWarper:

** Apparently, [[http://www.scp-wiki.net/scp-2412-j they caught him]] in a joke article and put him in containment. However, he must leave every December 24th each year to deliver presents for Christmas. Otherwise, a worldwide [DATA EXPUNGED] will happen.

** [[http://www.scp-wiki.net/scp-4666 SCP-4666]] is a remarkably unpleasant take on the jolly old guy.
* SantasSweatshop: [[http://www.scpwiki.com/scp-4666 4666]] AKA "[[{{Santabomination}} The Yule Man]]" is found to possess one of these: hidden somewhere deep underground, most of the children he targets are taken here - usually after butchering their families. They are tasked with making presents for the few targeted kids who manage to escape the Yule Man's attention without displeasing him, and they are not to stop for any reason: anyone who slows down or falls asleep on their shift is punished with starvation, beating, burning, or even with having their fingers bitten off; repeat offenders are ''eaten'' by the Yule Man. Worst of all, children who fall ill or can't work anymore [[HumanResources are recycled into raw material for fresh toys]]. And [[AndIMustScream not all of them die from this treatment]], incidentally - hence why the Foundation knows of the workshop at all.
* SapientTank: Two of mention [[http://www.scp-wiki.net/scp-802 SCP-802]], a French tank that patrols a small region and attacks any who come near it, and [[http://www.scp-wiki.net/scp-516 SCP-516]], a Soviet-made nonviolent (until pressed) tank.
* SaveOurStudents: [[http://www.scp-wiki.net/scp-2960 SCP-2960]], an entire high school production of ''Theatre/{{Urinetown}}'' (cast, crew, and orchestra) trapped in their auditorium and forced to perform every weekend since 2008 [[spoiler:(the ones who didn't commit suicide or were mysteriously killed because they didn't perform well were released in 2014, though they still unconsciously act out the play on schedule)]], apparently because their drama teacher was afraid for their future:

* ScaryBlackMan: Invoked with the D-Class assigned to perform 110-Montauk in ''[[http://www.scp-wiki.net/fear-alone Fear Alone]]'', [[spoiler:heightening the MoodWhiplash when he produces a copy of ''Goodnight Moon'']].

* ScienceIsWrong: [[http://www.scp-wiki.net/scp-033 The Missing Number]]. We missed a number. Whenever it interacts with anything electronic or math we use, the number breaks it.

** [[http://scp-wiki.net/qntm-s-proposal qntm's SCP-001 Proposal]] is a seemingly indestructible gemstone that's implied to contain something extremely dangerous.

** [[http://www.scp-wiki.net/scp-911 SCP-911]] is a can you can easily end up sealed into. There is something pretty malicious in there as well, and it wants to get out.
** [[http://www.scp-wiki.net/scp-1844 SCP-1844]] is a HellGate that is, miraculously, 99.6% contained. However, since this is the ''only'' (terrestrial) Hell-gate known to the Foundation at least one person wonders if this is actually a good thing:

** [[http://www.scp-wiki.net/scp-1661 SCP-1661]] has the special class "Archon" because it serves as one of these for another, much more dangerous entity. Containing it just makes things worse, so the Foundation maintains a very rare policy of non-interference, since 1661-A instances are not hostile and actively try to avoid hurting anyone.
* SealedGoodInACan: The rare SCP objects with the [[http://www.scp-wiki.net/system:page-tags/tag/thaumiel Thaumiel]] object class. These are [=SCPs=] with effects helpful to the Foundation's mission, and are often very tightly controlled and covered up under wraps. Use of these objects is usually very conservative, with some being completely unused and only activated as a contingency plan.
** The word's use as an object class started from [[http://www.scp-wiki.net/roget-s-proposal Roget's SCP-001 proposal]][[note]]Going even further back, the word itself was first used as an {{Arc Word|s}} in [[http://www.scp-wiki.net/thaumiel Project Thaumiel]], a series of SCP-001 related tales, and obscured inside [[http://www.scp-wiki.net/scp-1764 SCP-1764]].[[/note]], a building where Keter-class [=SCPs=] self-contained each other via cross interaction.
** It is also used in [[http://www.scp-wiki.net/scp-2000 SCP-2000]], a Foundation site with the ability to ''rebuild'' the world after an apocalyptic event. SCP-2000 was also one of the original popularizers of the Thaumiel class.
** It is the object class for [[http://www.scp-wiki.net/scp-179 SCP-179]], a benevolent goddess pointing out interstellar threats to earth.
** It has been retconned into [[http://www.scp-wiki.net/scp-1968 SCP-1968]] as the object's classified real object class, [[spoiler:a torus with the ability to rewrite history.]]
** [[http://www.scp-wiki.net/scp-2003 SCP-2003]] is a form of time travel that will let the Foundation see into the future destruction of humanity.
** [[http://www.scp-wiki.net/scp-2217 SCP-2217]] is a holy site for an offshoot of the Church of the Broken God, and was rated Thaumiel because it is intended to combat an XK scenario related to [[http://www.scp-wiki.net/scp-610 SCP-610]], the Flesh That Hates.
** [[http://www.scp-wiki.net/scp-2237 SCP-2237]] is a set of foundation spaceships intended to be launched several planets (some of which are the ones created by [[http://www.scp-wiki.net/scp-1795 SCP-1795]]) in the event of a major problem on Earth.
** [[http://www.scp-wiki.net/scp-2400 SCP-2400]] is a TimeDilationField with a ratio of 1 time unit outside the SCP corresponding to 140 time units inside it. [[spoiler:Except that it also completely nullifies the reverse entropic effects of [[http://www.scp-wiki.net/scp-2700 SCP-2700]], and turns it into a paradoxical energy reactor.]]
** [[http://www.scp-wiki.net/scp-2722 SCP-2722]], a starship containing the best of multiple universes created with the intention to help "maintain normalcy", would be reclassified into Thaumiel should it ever be used.
** [[http://www.scp-wiki.net/scp-2799 SCP-2799]] is effectively an anomalous object compass.

** [[http://www.scp-wiki.net/scp-1802 SCP-1802]]. Made to be constantly curious of the things around him, to collect them, and to cache it away in containers.
** [[http://www.scp-wiki.net/scp-1312 SCP-1312]] is a much darker example. Call it BlackComedy if you can laugh at a man who got "cut apart with sharp things".
** [[http://www.scp-wiki.net/scp-001-ex-j SCP-001-EX-J]]. Something like ''SCP Foundation: Prehistoric Edition''.
** [[http://www.scp-wiki.net/scp-1870 SCP-1870]] is a combination of both this and a TakeThat on [[SelfInsertFic an SCP-related roleplaying forum]].
* SelkiesAndWereSeals: [[http://www.scp-wiki.net/scp-3477 Harold Holt]] claims to have become immortal by donning a cloak made of sealion skin.
%%** [[http://www.scp-wiki.net/scp-5561 SCP-5561]] contains a very dark variation on this trope.
* SenselessSacrifice: In [[http://www.scpwiki.com/shaggydredlocks-proposal SCP-001: S.D. Locke's Proposal]]. A D-class agrees to try drawing instances of SCP-001-A away from the others, on the grounds that he gets a gun and one bullet for it. He kills himself, with him and the researchers hoping that it will spare him from becoming another one of those blob monsters...but not only do they get ahold of him and drag him out into [[spoiler:the sunlight]], he [[CameBackWrong comes back and becomes yet another one of them]]. About 3 1/2 years later, [[spoiler:Dr. Igotta does the same, using pills to quietly end herself, hoping that she won't draw the attention of the ever-growing sun blobs (the alternative being a gun, which she notes would draw their attention). Unfortunately, [[TheFourthWallWillNotProtectYou the reader]] finds that she's become another one of them.]]
* SerialKiller: [[http://scp-wiki.wikidot.com/scp-5846 SCP-5846]] is a man who murders numerous serial killers between the 1960s and 1970s, long before their crimes become public.

** [[http://www.scp-wiki.net/scp-682 SCP-682]] appears to have assumed this role, as witnessed by the protests on the site forums whenever anyone suggests killing it off for good. The original one was [[http://www.scp-wiki.net/scp-173 SCP-173]].

** Averted with the [[http://www.scp-wiki.net/the-big-list-of-overdone-scp-cliches Cliche List]], in which a serious topic ([[ExactlyWhatItSaysOnTheTin Cliches writers probably shouldn't copy]]) is written in something approaching [[Website/FourChan /b/]]-style.

* SetRightWhatOnceWentWrong: The excerpts of [[http://www.scp-wiki.net/scp-4264 SCP-4264]] tell a story of a teacher discovering his RealityWarper powers through the questions he writes. After he draws the attention of the Global Occult Coalition which culminates in the destruction of his home city (to which he responds with a meteorite aimed directly on their base), the final question in conjunction with the SCP's event of discovery implies that he's successfully traveled back in time to stop his past self from discovering and exploiting this power.

** [[http://www.scp-wiki.net/scp-434 SCP-434]]: A table that, when there is a subject and eight chairs, causes seven correspondingly "sinful" clones of the subject to appear; if the "clones" are killed, that aspect of the subject's personality is destroyed (for example, the death of Sloth destroys the ability to sleep).
** [[http://www.scp-wiki.net/scp-1215 SCP-1215]]: (Actually eight sins — Pride is divided into Vanity and Hubris.) An illuminated manuscript that causes people to self-destruct with a deadly sin theme, except for Vanity where the danger is acting so irritating ''other people'' attack you.
** [[http://www.scp-wiki.net/scp-1133 SCP-1133]]: An IV stand that can extract or inject fluids pertaining to the seven sins; for instance injecting sloth makes one lazier, while extracting it makes one more productive.

** PlayedForLaughs with [[http://www.scp-wiki.net/scp-4950 SCP-4950]], where [[ApocalypseCult the People of the Lie's]] incredibly bizarre ritual to summon their god utterly failed despite all of the hard work that they put into it.
** [[http://www.scp-wiki.net/scp-5000 SCP-5000]] possibly provides a rare [[DoubleSubversion Double Subverted]] example of this trope. [[spoiler: Unfortunately, even though Pietro eventually reached his goal, humanity had been essentially exterminated by that point by the [[FaceHeelTurn Foundation]], he is left with no answers, and he could only make SCP-055 come into contact with SCP-579 by dropping the former from a fatal height, causing him to die before his remains were transported to the main SCP universe. Thankfully, this still reset the timeline and saved humanity. However, the DoubleSubversion comes into play when one realizes that, thanks to this timeline reset, whatever entity that the alternate Foundation found within the collective unconsciousness of mankind and was trying to fight by exterminating humanity is ''still out there'', and now there's nothing stopping it from pursuing whatever its goals are in granting humanity empathy. [[RayOfHopeEnding Though since the Foundation has SCP-5000 now, they may be able to rediscover it and find a way to stop its nefarious plans]] without resorting to a FinalSolution.]]
** [[http://www.scp-wiki.net/scp-5999 SCP-5999]] has a complex narrative presented using a high-tech layout and has ineffective warning systems for what is apparently part of the containment protocols (even though reading more of the article slowly unseals whatever is being contained, there are seemingly no attempts to stop the reader by force.) [[spoiler: It's all completely irrelevant, as it's really a means to invoke this trope and execute [[http://www.scp-wiki.net/sandrewswann-s-proposal Protocol ZK-001]] (simulated using the JumpScare at the very end.)]]
** [[http://scp-wiki.wikidot.com/144-hour-jam-contest A contest stimulated those]], won by [[http://scp-wiki.wikidot.com/scp-4290 SCP-4290]], a SealedEvilInACan that [[spoiler:once awakened, dies of malnutrition after millennia underground!]].
* ShareTheMalePain: This is [[http://www.scp-wiki.net/scp-5972-j SCP-5972-J]]'s main function to males when described.

** The closest thing we have to an in-story explanation is that this was a [[http://www.scp-wiki.net/forum/t-192324/scp-like-foundation-personnel#post-620884 long overdue reaction to the lack of oversight created when the military elements in the Foundation leadership left]]. The processes are still ongoing. See [[http://www.scp-wiki.net/forum/t-192324/scp-like-foundation-personnel this forum thread]] for more info.
** Also, [[http://www.scp-wiki.net/chowderclef "Chowderclef"]] is an official retcon of all of Dr. Clef's quirky escapades… sort of. Clef (the writer) ultimately decided to be ambiguous about it and let readers decide for themselves whether or not the escapades still count.
** [[http://www.scp-wiki.net/a-suicide-note "A Suicide Note"]], a suicide note left behind by Alto Clef, bemoaning that everyone ''thinks'' he's a Reality Warper that goes on wacky adventures, when he's actually a [[PowerNullifier reality anchor]] that breaks anomalies just by being near them. In one paragraph, he helps shoo out the other "LOL Foundation" clowns: Kondraki ("in a psych ward"), Bright (betrayed the Foundation to the Serpent's Hand and was finally allowed to die), Rights (merged with a biological SCP she was working on), and Crow ({{Mercy Kill}}ed by Clef). Worse still, he claims that all the "LOL Foundation" stuff was a direct result of [=SCP-239=] screwing with reality ForTheLulz. [[spoiler:In the end, the Foundation finds evidence that Clef definitely shot himself in the head... but no body.]]
** The introduction of Dr. Lucius Veritas to [[http://www.scp-wiki.net/scp-914 SCP-914]]'s extended testing logs was done in a bid to apply this trope to said logs. To his creator, it was a stunning success. [[SurroundedByIdiots To Veritas himself, not so much]].
** The Decommissioned class mentioned above has its own history with this trope, initially starting as a way to "properly" dispose of bad articles by having the Foundation staff destroy them in humorous ways. It was eventually shut down due to it turning into the aforementioned wildly unprofessional contest of seeing who could destroy an SCP in the funniest way, but was reactivated both in-universe and out-of-universe with very strict standards - commenting in-universe on the previous treatment of the class in the process - in a bid to destroy [[http://www.scp-wiki.net/scp-4456 SCP-4456]], which the Foundation could not contain without unethically sending away billions of dollars to the Spanish government in the past (or causing a time paradox, for that matter.)

** [[http://scp-wiki.wikidot.com/scp-2460 SCP-2460]] references existing knowledge regarding the nature of dark matter, and builds the behavior of the ambiguously anomalous alien dark matter satellite (and its disastrous potential effects) from it.
** [[http://scp-wiki.wikidot.com/scp-1348 SCP-1348]] is based heavily on real-life details of the Abrahamic mythology, some of which can be found on the [[http://scp-wiki.wikidot.com/ophite-s-personnel-file author's page]].
** [[http://www.scp-wiki.net/scp-2223 SCP-2223]], an SCP mostly about an anime image that manipulates search algorithms to go to the top of the search results, has a massive section detailing the specific mechanics behind the mathematics of search engine algorithms and the mathematics of identifying the anomaly.
** [[http://www.scp-wiki.net/scp-2123 SCP-2123]] involves tons of technical discussions about quantum anomalies in a supercollider and the frightening implications of it.
** [[http://www.scp-wiki.net/scp-2747 SCP-2747]] involves an EldritchAbomination "antinarrative" that erases any narrative it is featured in from existence (including narratives within narratives) called the "anafabula". [[https://en.wikipedia.org/wiki/Fabula_and_syuzhet "Fabula"]] is a real term from the Russian formalism school of literary criticism that refers to the chronological arrangement of events within a story. Thus an "anafabula" (using the Greek root "ana-", meaning "up", "against", "back", or "re-"), can literally be read to mean "against chronological order", [[ExactlyWhatItSaysOnTheTin which is exactly what the entity does.]]
** [[http://www.scp-wiki.net/scp-3966 SCP-3966]] has a ''lot'' of accurate technical information on neuroscience to describe the effects of the anomaly, [[ViewersAreGeniuses without any exposition]].
** [[http://www.scp-wiki.net/scp-4220 SCP-4220]] is largely focused on both an analysis of American occultism during the 1950s and 1960s and the lives of Creator/{{Aleister Crowley}}, Jack Parsons, and Creator/LRonHubbard. Aside from the obvious breaks from history (i.e., Crowley and Parsons were never forced by the government into using {{Magitek}} to get to the Moon before the Soviets did in our world), all of the details given to both the lives of the three aforementioned men and the subculture of mid-20th century American occultism are real.
** Virtually all references given to various mental illnesses and insights into abusive relationships given over the course of [[http://www.scp-wiki.net/scp-4231 SCP-4231]] are disturbingly accurate.
** Almost all of the events described within [[http://www.scp-wiki.net/scp-4882 SCP-4882]], from the unanimous acceptance of leap seconds to the Bitcoin mining fire, happened in real life.
** Most of the details given about the various cultures of the Middle East during the Bronze Age (especially in regards to that of Sumeria and Mesopotamia) in [[http://www.scp-wiki.net/scp-4960 SCP-4960]] are surprisingly accurate and [=well-researched=], especially in regards to how the worship of various gods and goddesses was conducted at the time.
** [[http://www.scp-wiki.net/grant-request-for-the-construction-of-an-interstellar-scienc The Prometheus Labs GOI Format]] goes so far as to provide citations ''to real scientific journals.''

** [[http://www.scp-wiki.net/scp-3256 SCP-3256]] is a meme embedded within the M.O. of a serial killer; this killer, known as The Binder, captured the public imagination InUniverse to such a degree that episodes of procedural shows like ''Series/CriminalMinds'' were based off of his killings... which just spread the meme further.
** [[http://www.scp-wiki.net/scp-2614 SCP-2614]] is a DVD of ''Series/TheSopranos''[='=]s Fifth Season that a viewer can "control", essentially guiding a camera through the show and seeing what happened in the background of some episodes, such as Tony having a breakdown in the shower. It can even enter other media in ''The Sopranos'', including a showing of ''WesternAnimation/{{Snow White|AndTheSevenDwarfs}}'', to produce [[RecursiveReality Recursive Realities]]. [[spoiler:Things get ''really'' weird when a researcher tries to enter a show within a show ''within'' a show.]]

** Literally with two players of [[http://www.scp-wiki.net/scp-286 SCP-286]], who are [[spoiler:He-Who-Made-Light and He-Who-Made-Dark, warring elemental brothers]]:

** [[http://www.scp-wiki.net/scp-2819 SCP-2819]], two mutually antagonistic beetles. One is white with black marks and can make people feel happy, and the other is black with white marks and makes people depressed (the former just wants people [[SlidingScaleOfIdealismVsCynicism to see the truth about the world]] and the depression is due to its limited powers). Why are they here? [[spoiler:Apparently the Light and Dark brothers (or similar entities) annoyed their father so much he turned them into beetles.]]
** Elderly twin sisters [[http://www.scp-wiki.net/scp-1884 SCP-1884-A and -B]] — SCP-1884-A has a mild, almost ExtremeDoormat-level personality and looks like a normal human aside from her fused, handless arms, while SCP-1884-B is a very aggressive and sassy old lady who is nothing ''but'' hands.

** [[http://www.scp-wiki.net/scp-3512 SCP-3512 "The More You Know"]]: The Pick-Up Artist book has 12 chapters, then 12 additional chapters with meaningful anagrammed titles. For example "Chapter 12 [12] You Know Theorem" introduces advanced mathematics and "Chapter 12 [14] Where To, You Monk?" talks about a monk-like architect; additionally "The book's afterword is composed of more than 15,000 anagrams of the book's title, laid out in spiral and triangular patterns."
** There's also the [[http://www.scp-wiki.net/scp3000contesthub SCP-3000 contest page]]: "[[BadassCreed We die in the darkness so you can live in the light]]" becomes "He sews kindhearted sin contagiously. [[{{Horror}} Think evil.]]"

** [[http://www.scp-wiki.net/scp-553 SCP-553]], butterfly-like crystal lifeforms.
** [[http://www.scp-wiki.net/scp-2300 SCP-2300-14]] is the silicon version of the tiny golems.

* SinisterMinister: [[http://scp-wiki.wikidot.com/scp-1832 SCP-1832]], who ''literally'' feeds off of suffering.

* SlashFic: For April Fools Day 2017, an author wrote a furry fanfic of [[http://scp-wiki.wikidot.com/scp-1893 SCP-1893]] (a minotaur entity that can only be documented in narratives) and [[http://scp-wiki.wikidot.com/scp-2547 SCP-2547]] (the Navajo Coyote, who survives and is powered by various narratives about him). It's an addendum to the original SCP-1893, with the dialog between the two characters describing the cross-proliferation between narratives of 1893 and 2547 leading to Coyote/Minotaur slash fics forming. It's ''very'' NSFW, so no link will be given.
* SleepWalking: [[http://scp-wiki.net/scp-5586 SCP-5586]], a sleepwalker who has been known to turn up in a variety of odd locations, including the Queen's bedroom, the Oval Office (where he threw his slipper at President Nixon), and the ''surface of the Moon''.

* SlidingScaleOfSillinessVersusSeriousness: [[invoked]] The wiki itself slowly slid from a general silly mood to a more serious mood. Early on when things are still messy, articles can often have dead-serious (sometimes ''so'' dark and serious they just seem silly again) descriptions, [[MoodWhiplash then end with a silly addendum]], making things seem rather silly on the grand scale. The ShooOutTheClowns mentioned above purged most of the articles that are deemed "too silly", and newer, more serious writers turned the wiki down the serious path. Nowadays, the wiki as a whole is pretty serious, though individual articles/canons may still have some silly themes, but tend to aim away from being potentially {{Narm}}-inducing like some of the early works and are instead treated in a serious way. That being said, there are still a high number of strange or funny articles, especially among the newer series, though these tend to avoid {{Narm}} by instead more emphasizing the {{Surreal Humor}} of dealing with bizarre things like [[http://www.scp-wiki.net/scp-504 SCP-504]][[note]]a species of tomato [[ProducePelting that violently hurl themselves at anything cracking a bad joke within earshot]][[/note]], [[http://www.scp-wiki.net/scp-1472 SCP-1472]][[note]]an anomalous strip club which had one act consist of ''Velociraptors'' in {{Meido}} costumes[[/note]], [[http://www.scp-wiki.net/scp-2020 SCP-2020]][[note]]an alien coming up with random sci-fi story ideas[[/note]], [[http://www.scp-wiki.net/scp-3922 SCP-3922]][[note]]a device that causes super-powered police to bust into any televised work to arrest lawbreakers[[/note]], [[http://www.scp-wiki.net/scp-4950 SCP-4950]][[note]]an ApocalypseCult almost succeeding in using both ''VideoGame/{{Fortnite}}'' and an ''Toys/{{amiibo}}'' to summon their DestroyerDeity[[/note]], [[http://www.scp-wiki.net/scp-5983 SCP-5983]][[note]]a bizarrely symbiotic connection between explosions within a small county in Wisconsin & the efficiency of the New York City Subway[[/note]], and [[http://www.scp-wiki.net/scp-6599 SCP-6599]][[note]]an anomalous individual with the appearance [[LargeHam and hamminess]] of Wrestling/ScottSteiner that initially teleported to and beat up people that they got into arguments with on hobbyist forums before they went into anger management[[/note]] - all of which is almost always described in [[TheComicallySerious an unflappably scientific demeanor]].
* SlidingScaleOfVillainThreat: A mention of "[[http://www.scp-wiki.net/system:page-tags/tag/k-class-scenario#pages K-class scenario]]" is usually for XK-class, Global Threat (or [[ApocalypseHow Planetary Extinction\Annihilation]]). Most Euclids range from Personal to City Threat ([[ApocalypseHow Class 0]]), while Keter is usually for City up to Global ([[ApocalypseHow Class 1 to X]]; Class 4 gets even an specific term, as "GH-Class Dead Greenhouse"). And a few, such as invading aliens, are implied to reach Multi-Planetary Threat levels.

** Both [[http://www.scp-wiki.net/twistedgears-kaktus-proposal TwistedGears-Kaktus' SCP-001 Proposal]] and [[http://www.scp-wiki.net/scp-4882 SCP-4882]] deal with the Broken God being rebuilt. However, the former is mechanical, built by a small group of followers, and destroyed by physical forces. Meanwhile, the latter is electronic, built by technological society as a whole, and kept at bay by diplomacy. And where the former ends on a denouement, SCP-4882 ends on a cliffhanger.
** [[http://www.scp-wiki.net/scp-6000 SCP-6000]] can be read as one to '''[[http://www.scp-wiki.net/taboo the article that cannot be referred to as SCP-4000]]'''. Both are focused around anomalous forests connected in some way to the Wanderer's Library, but while the former is slowly spreading across the planet and [[spoiler:[[HostileTerraforming transforming the Earth into another extension]] of the Library]], the latter is confined to a single location and serves as a safe haven for [[spoiler:the last surviving members of TheFairFolk]]. And while the former article is ultimately optimistic and about the spreading of knowledge ushering in a new world, the latter is cynical and largely about how knowledge can be being deliberately hidden and forgotten due to history being WrittenByTheWinners.
** [[http://www.scp-wiki.net/scp-6001 SCP-6001]] is one to [[http://www.scp-wiki.net/scp-5000 SCP-5000]]. If SCP-5000 is a DarkerAndEdgier story about the Foundation having a FaceHeelTurn and causing a hellish {{Dystopia}} as they attempt to KillAllHumans, SCP-6001 is a LighterAndSofter story about a peaceful {{Utopia}} being created by all known Groups of Interest uniting together for the mutual benefit of ''both'' humanity and the anomalous.

** [[http://www.scp-wiki.net/scp-4100 SCP-4100]] is one for the now-deleted Tale [[https://web.archive.org/web/20171222074856/http://www.scp-wiki.net:80/5700-years-later "5700 Years Later,"]] which also dealt with humanity fleeing an abandoned Earth due to rampaging [=SCPs=] and managing to [[spoiler:[[DidYouJustPunchOutCthulhu take out a hostile god-like entity in the process]]]].
** [[invoked]] [[http://www.scp-wiki.net/scp-4231 SCP-4231]] is one to both [[http://www.scp-wiki.net/your-circuits-dead-theres-something-wrong "Major Tom"]] and [[http://www.scp-wiki.net/portraits-of-your-father "Portraits of Your Father,"]] two Tales both created by the [=SCP=] article's author that took several [[EnsembleDarkhorse "titans"]] of site lore[[note]]Bright, Kondraki, and now Clef respectively[[/note]] and [[{{Deconstruction}} darkly analyzed them]] while looking into what made them the men they are today.
** [[http://www.scp-wiki.net/scp-4444 SCP-4444]] as a whole is one to the goofier early [=SCP=] articles and Tales focused around {{Author Avatar}}s and {{Mad Scientist}}s, such as [[http://www.scp-wiki.net/incident-239-b-clef-kondraki "Incident 239-B"]] and [[http://www.scp-wiki.net/duke-till-dawn "Duke 'till Dawn"]].
** In a weird way, [[http://www.scp-wiki.net/scp-4960 SCP-4960]] is one to [[http://www.scp-wiki.net/scp-001-o5 Dr. Bright's 001 Proposal]] in how it serves as an OriginStory for both the Foundation & some of its [=GOIs=] while taking place in the early twentieth century & being colored by the prejudices of the time. Abernathy even fits nicely into the role of the [=O5=] from Bright's Proposal as the narrator of the [=4960=] article through his letters.
** [[http://www.scp-wiki.net/scp-5031 SCP-5031]] can be seen as one towards [[http://www.scp-wiki.net/scp-3114 SCP-3114]], as both are articles based around taking a stereotypical "murder monster" [=SCP=] concept and humanizing the subject by highlighting the underlying tragedy of their situations.

** [[http://www.scp-wiki.net/scp-1330 SCP-1330]] is a universal garbage dump. One object found is a toilet bowl full of polished diamonds.
** [[http://www.scp-wiki.net/scp-391 SCP-391]] looks like a normal barn owl… probably because it ''is'' a normal barn owl. Well, except for the fact that when it eats, its waste pellets are made of various precious metals, instead of bone and fur (like you would find in ordinary owl waste pellets). So far, the Foundation has found pellets made of gold, silver, platinum, and indium.
** [[http://www.scp-wiki.net/scp-1618 SCP-1618]] is an Are We Cool Yet? artifact that can turn waste products into this and objects of value into refuse that includes genitalia and used nuclear rods.
* SolitarySorceress: [[http://www.scp-wiki.net/scp-352 SCP-352: Baba Yaga.]]
* SophisticatedAsHell: Even when trapped in a demonic EldritchLocation ([[http://www.scp-wiki.net/scp-1983 SCP-1983]]), one Agent still manages to write an informal SCP Report.

* SpeciesSpecificAfterlife: There are numerous stories depicting possible afterlives for humans. And then there's [[http://www.scp-wiki.net/scp-1557 SCP-1557]], which is a version of Hell specifically for giraffes.

* SpidersAreScary: [[http://www.scp-wiki.net/scp-859 SCP-859]] is pretty much ''built'' around this concept.

** [[http://www.scp-wiki.net/scp-859 SCP-859]] can apparently make these appear from out of nowhere.
** [[http://www.scp-wiki.net/scp-1006 SCP-1006]] is a huge colony of [[TalkingAnimal English speaking]] Marxist spiders.

** [[http://goc.wikidot.com/start Global Occult Coalition]] (reintegrated into the main site as a [[http://www.scp-wiki.net/goc-hub-page canon]] due to a lack of activity)

* SplitPersonality[=/=]MentalStory: [[http://www.scp-wiki.net/scp-2442 SCP-2442]] can make Foundation staff and SCP objects disappear and can speak with an invisible entity [[spoiler:because the Foundation-verse exists inside a very disturbed woman's head (the "invisible" entity) and he is having her confront her traumatic memories (the objects) and eliminating her alternate personalities (the Foundation staff). By the way, the Groups of Interest working against the Foundation are therapeutic techniques (IE Are We Cool Yet? could be art therapy). Naturally, the Foundation is horrified by the idea that their whole world is just be one person's elaborate delusion]]:

* SpontaneousHumanCombustion: [[http://www.scp-wiki.net/scp-081 SCP-081]] is a virus that causes SpontaneousCombustion — in fact, [[HistoricalInJoke it's responsible for all recorded instances of it]].

** Possible one: [[http://www.scp-wiki.net/scp-1342 SCP-1342]] is [[spoiler:a message from an alien race destroyed by humans 40,000 years in the future. Unfortunately for them, thanks to the message, we know that they were on the verge of faster-than-light "time" travel before we destroyed them and they could've annihilated us, but didn't because they were too grateful for our radio broadcasts enhancing their own civilization.]]
** Project Thaumiel: [[http://www.scp-wiki.net/pila Pila]].
* StalkerWithACrush: [[http://www.scp-wiki.net/scp-1269 SCP-1269]], a very possessive, letter-writing, [[spoiler:ambulatory, telekinetic, and extremely violent]] mailbox.

* TheStarsAreGoingOut: [[http://www.scp-wiki.net/scp-2154 SCP-2154]] is a telescope that can see space in real time, and while the stars aren't disappearing they are being blocked by a mysterious opaque "cloud" that is getting closer and closer to Earth.
* StartOfDarkness: A work in progress (also a proposed SCP-001) shows how everything started, and by everything we mean how the [[http://www.scp-wiki.net/scp-001-o5 Foundation and its rivals or enemies]] came into existence.

** [[http://www.scp-wiki.net/scp-1915 SCP-1915]] is a RealityWarper that invokes this for himself within a certain radius of his presence. He is unaware of his containment and [[PowerIncontinence has limited control of his powers]].
** [[http://www.scp-wiki.net/scp-4121 SCP-4121]] is a spacetime paradox that prevents events from occurring past a certain point. On the one hand, it means many potentially apocalyptic [=SCPs=] have not yet breached containment. On the other hand, it also means the foundation hasn't been able to progress many containment or termination procedures past the conceptual stage.

** Several of the SCP numbers are this. [[http://www.scp-wiki.net/scp-1225 SCP-1225]], for example, is "The Worst Christmas" (Christmas is generally observed on December 25, or 12/25 using the mm/dd system common in the US).
** [[http://www.scp-wiki.net/scp-1226 SCP-1226]] seems to be playing on the phrase "[[spoiler:bomb(ing) them back to the Stone Age]]".
** [[http://www.scp-wiki.net/scp-1710 SCP-1710-1]] is described as having been called in their home reality "The Serrated Void," and spends most of their time describing how sharp they (literally) were. Also, they usually talk in dark and foreboding passages, occasionally mentioning how they used to have enough power in their home reality where they could [[EyeScream "pluck out the eyes of gods"]] and [[PhysicalGod "make the universe our whetstone."]] In other words, [=SCP-1710-1=] is a ''literal'' edgelord.
** [[http://www.scp-wiki.net/scp-4634 SCP-4634]] is a set of "Out of Order" signs first found affixed to the insides of several stone monuments' doors. [[spoiler:Removing them caused the universe to enter a state of perfect order ([[OrderIsNotGood unfortunately, this also meant it could no longer sustain life]]).]]
* StringyHairedGhostGirl: [[http://www.scp-wiki.net/scp-1692 SCP-1692]] usually takes this form.
* SturgeonsLaw: The [[http://scp-wiki.wikidot.com/history-of-the-universe-hub "History Of The Universe"]] recap on the website history notes that this is in full force every time there's an uptick of newcomers: "Numerous new SCP articles were being posted every day, and many of them were extremely poor."

** [[http://www.scp-wiki.net/the-big-list-of-overdone-scp-cliches The Big List Of Overdone SCP Cliches]], part of "How To Write An SCP":

** There's also the [[http://www.scp-wiki.net/scp-foundation-the-movie SCP Foundation movie.]] The fact that [[Film/TheRoom Tommy Wiseau]] and [[Series/WinBenSteinsMoney Ben Stein]] are in it should already be setting off alarms in your head.
** [[http://www.scp-wiki.net/protocol-gattai "Protocol GATTAI"]] is this combined with literally every overused anime trope and reference the writer could think of.

** [[http://www.scp-wiki.net/scp-1233 SCP-1233 ("Mammal Terraformer")]]. Any mammal within 7 meters of SCP-1233 feels fear and revulsion. In addition, any human that close feels a desire to flee the area.
** ''[[http://www.scp-wiki.net/scp-303 SCP-303 ("The Doorman")]]. When SCP-303 materializes behind a door, anyone trying to open the door from the other side will feel a paralyzing fear that lasts until SCP-303 de-materializes again.
* SupernaturalPhone: The SCP Foundation has a couple of these: [[http://www.scp-wiki.net/scp-086 SCP-086]], [[http://www.scp-wiki.net/scp-145 SCP-145]], [[http://www.scp-wiki.net/scp-270 SCP-270]], [[http://www.scp-wiki.net/scp-400-arc SCP-400-ARC]], [[http://www.scp-wiki.net/scp-467 SCP-467]], [[http://www.scp-wiki.net/scp-519 SCP-519]], and [[http://www.scp-wiki.net/scp-2922 SCP-2922]].

** [[http://www.scp-wiki.net/scp-1470 SCP-1470]]. It's a spider who can communicate through telepathy. The Foundation no longer has to keep an eye on it, because it's dead. Spiders of that species only live for four months, and once those four months were up, it died of old age. Similarly, there's [[http://scp-wiki.wikidot.com/scp-3774 SCP-3774]], where [[spoiler:the InterspeciesRomance between a human male janitor and a cyborg female mosquito (ItMakesSenseInContext) only lasted for around a month [[MayflyDecemberRomance because that's the typical lifespan of a mosquito]]]].
** In a different vein, there's [[http://www.scp-wiki.net/scp-1575 SCP-1575]]. It is a statue/fountain that, over the course of about a month, slowly transforms animals into humans when they drink from it. What sounds like a [[UsefulNotes/FurryFandom furry fetishist's dream]] quickly becomes a nightmare when you look at the concept from a real-world point of view. Simply put, animals and humans are biologically different for a reason. Only three tested animals managed to survive the transformation and only one of those three transformed fully with no unwanted results. The rest died from TransformationTrauma related defects, due to biological differences. Examples include a field mouse whose cardiovascular system shut down because it couldn't keep up with the rate her body was growing, a tiger whose organs failed after just ''four days'' because of the sedatives she was given, a parrot whose skeleton shattered in various places because, like the field mouse, it couldn't keep up with the rest of her (her wings did apparently manage to form a set of pseudo-hands, though) and some undisclosed but horrific incident caused because a dog used for testing was unknowingly affected with intestinal parasites.
** [[http://www.scp-wiki.net/scp-4974 SCP-4974]] was an attempt to bring [[Franchise/{{Pokemon}} Pikachu]] to life by means of hundreds of game cartridges, yellow sea sponge remains, the basic organs and cells needed to create a new organism, and 21st-century alchemy. It worked, but instead of giving HarmlessElectrocution to its recipient (the creator's son) as the anime did early on, it just killed the boy outright, something that the creator [[DrivenToSuicide killed himself over.]] Worse, as it's still technically a mutant sea sponge growing in a foreign environment, the Foundation believes it can't even think, unlike real Pokemon.
** [[http://scp-wiki.wikidot.com/scp-ex Every now and then]], the Foundation investigates a reported phenomenon that turns out to be a hoax or have a mundane cause.

** From [[http://www.scp-wiki.net/experiment-log-t-98816-oc108-682 Experiment Log T-98816-OC108/682]]: "Notes: This is the official story and we're sticking to it. The alternative, that someone tried to murder Dr. Clef by deliberately putting him in the same room as SCP-682, is completely inconceivable. O5-7"
** No, Dr. [[spoiler:Kondraki]] [[http://www.scp-wiki.net/incident-239-b-clef-kondraki didn't lose his temper and attempt to murder Dr. Clef]]; Clef ''accidentally'' slipped out of his chair and bashed his head against the edge of his desk (nine times), and that's why he'll never walk again.
** [[http://www.scp-wiki.net/scp-2602 SCP-2602, which used to be a library]], has all the things found in a former library has like radiation, shrines, and a waste disposal pit, which are normal things found in a building that used to be a library.

** [[http://www.scp-wiki.net/scp-409 SCP-409]], a crystal that turns anything it touches (except, ironically, granite) into more of itself.
** There's also [[http://www.scp-wiki.net/scp-602 602]], an invisible sculptor that supposedly turns humans into statues. At least in the story it's based on.
** [[http://www.scp-wiki.net/scp-1013 SCP-1013]], basically a cockatrice. It calcifies the outer layer of your body, then happily pecks a hole in you and eats what's inside.
* TakeUpMySword: In [[http://scp-wiki.wikidot.com/mackenzie-s-proposal Dr. Mackenzie's Proposal of SCP-001]], The Administrator had passed the job of finishing the legacy and stopping the Corruption on to the Foundation, when he realized he was dying.
* TakingTheBullet: [[http://www.scp-wiki.net/scp-2325 SCP-2325-2]] forces those who wear it to do this, whether the "bodyguards" want to or not.

** [[http://www.scp-wiki.net/scp-516 SCP-516]], a sentient T-55 main battle tank. Interestingly, this is one of the more benign sentient [=SCPs=], being unwilling to fire on unarmed or nonthreatening targets. When threatened by an armed D-class who was handcuffed to another, unarmed D-class, it even precisely aimed a shot to kill the shooter without seriously harming the unarmed target. When this test was repeated with a DeadMansSwitch on the armed D-class that would make the unarmed D-class explode, SCP-516 stopped the test before it began by [implicitly] killing the supervising researcher. Though apparently, it ''did'' decide to autonomously fire on a D-class who was apparently guilty of treason in the country the tank came from. Tellingly, when SCP-978 (a camera that reveals hidden desires) was used to take a picture of it, the picture showed it frolicking through a meadow, covered in flowers.
** [[http://www.scp-wiki.net/scp-802 SCP-802]] as well, although it's substantially less intelligent.
* TechnicallyLivingZombie: The "cured" Foundation members in [[http://www.scp-wiki.net/scp-5000 SCP-5000]] are still alive, but feel no pain or fear and refer to those who do as "live ones". [[spoiler: It's implied that they sacrificed some core element of their humanity itself thanks to discovering it to be unnatural and repulsive since it is assumed that humans originally ''do not have emotions at all'' (or at least not certain ones such as empathy).]]

* TestosteronePoisoning: [[http://www.scp-wiki.net/scp-1657 SCP-1657]], '''MAN EGGS''':

* ThereIsNoKillLikeOverkill: The appropriately named [[http://www.scp-wiki.net/scp-2270 "An Unnecessary Utilization of Excessive Force"]], where an ancient god summons an arm out of the Sun to destroy whatever he is ordered, a force of estimated 275 petajoules (more than [[https://en.wikipedia.org/wiki/Tsar_Bomba the biggest bomb ever detonated]]).
* TheyWouldCutYouUp: If it wasn’t for the fact that they couldn’t keep studying you afterwards... [[http://www.scp-wiki.net/interview-507-g "Oh. Bugger."]]

* ThingsThatGoBumpInTheNight: The mythical Voice-Taker, described in [[http://scp-wiki.net/scp-5768 SCP-5768]] is inspired by various real-world boogeyman legends of monstrous figures that punish naughty children. In this case, it's the ghost of a man born with a mouth two sizes too big who was robbed of his own ability to speak, and now steals the voices of children who lie, swear, and are rude to their elders. Also possesses a WeirdBeard made out of flies and maggots.

* TimePolice: [[http://www.scp-wiki.net/SCP-1780 SCP-1780]], AKA the Department of Temporal Anomalies aka Research and Containment Team Δt (Delta-t). They {{Unperson}}ed themselves from the timeline that the SCP-1780 document exists in, but they still do work in other timelines/canons.
* TitleDrop: [[http://www.scp-wiki.net/the-friday-exhibition The Cool War]] has Joey note how The Critic's group and the other anartists are in "The war of who's cooler... The Cool War," before immediately adding that it sounded stupid and to forget it.
%%* TomatoSurprise: [[http://www.scp-wiki.net/scp-009-j SCP-009-J]]

** One instance of the use of [[http://www.scp-wiki.net/scp-1543-j SCP-1543-J]] (which was built by the Foundation in the 1600s where their solution to destroying things was to fire them into the sun, regardless of practicality), where they fired a tree that fed off of energy and grew limbs that could attack people, ended with the entire ruling council of the Foundation executed for "gross stupidity and incompetence."
** The file on Dr. Clef's proposal for SCP-001, which is implied to be the Angel that guards the gates of the Garden of Eden, details another example of this from the Foundation. After finding that the angel will destroy anything that comes with 1000 metres of it, they try various tricks, such as sending a D-class at it (SCP-001 told him to "LEAVE", and also obliterated his handlers), 100 drones (all destroyed), a missile (destroyed, along with the launch-site and it's personnel), SCP-076 (implied to be the biblical Abel, [[NoJustNoReaction who absolutely refused to go near it]]) and SCP-073 (an individual implied to be the biblical Cain, who had an unspecified but even more violent reaction to it than Abel). After this failed, the Foundation decides to use [[NukeEm a SSBN in the Indian Ocean]] to try and see if they can make a dent in SCP-001. The test date was [[http://en.wikipedia.org/wiki/2004_Indian_Ocean_earthquake_and_tsunami the 24th of December, 2004.]]
** Tom Miller, [[http://www.scp-wiki.net/scp-2875 the mayor of a town]] [[GoneHorriblyRight which was accidentally cursed]] to [[BearsAreBadNews constantly summon bears]] with AsteroidsMonster powers, still thought it important that he leave his phone number on an exterminator's voicemail ''while a bear was mauling him to death.''
* TowerOfBabel: [[http://www.scp-wiki.net/scp-1643 SCP-1643]]: Someone from the Horizon Initiative found it and upgraded it [[spoiler: in order to ''[[NukeEm nuke heaven]]'']].

* TranslatorMicrobes: [[http://www.scp-wiki.net/scp-2722 SCP-2722]], a dimension-hopping ship that appears wherever there's a threat to a universe's reality and a group working to protect it, has an ability that allows sapient beings to comprehend the "meaning" of any written language (as opposed to a literal translation). This is because it's covered in graffiti ranging from minute pheromone deposits to meters-high letters and this graffiti the only way for the current users to navigate the maze of modifications the previous users made.
* TrashOfTheTitans: The break room after [[http://www.scp-wiki.net/scp-885-j Researcher Jacobs uses it.]]

** [[http://www.scp-wiki.net/scp-1848 SCP-1848]] (who's more of a prankster than a trickster) "claim[s] to be no fewer than a hundred mythical and historical figures, including: [[Myth/NativeAmericanMythology Raven, Coyote]], [[Myth/NorseMythology Loki]], [[Myth/ClassicalMythology Hermes]], [[Literature/AnansiBoys Anansi]], [[http://en.wikipedia.org/wiki/Saci_%28Brazilian_folklore%29 Saci]], UsefulNotes/JohnFKennedy, and UsefulNotes/JesusChrist."
** [[http://www.scp-wiki.net/scp-2547 SCP-2547]] is Coyote himself. He wants to become more famous so the Foundation helps him with that to reduce the number of his manifestations that tend to turn people into canines.

* TropeName: [[http://www.scp-wiki.net/scp-1234-j SCP-1234-J]]. Most of [[http://www.scp-wiki.net/forum/t-399227/scp-1234-j its discussion thread]] also goes in that meta way.

** Also invoked with some multiversal performances of [[http://www.scp-wiki.net/scp-1763 SCP-1763]], an off-off Broadway theatre in New York. Performances range from screaming for hours to taking a hat off for hours.
* TheTunguskaEvent: [[http://www.scp-wiki.net/scp-873 SCP-873]] acquired its anomalous properties during the event; a connection is suspected.

* UltimateShowdownOfUltimateDestiny: In-Universe: If anything is lethal, it will sooner or later be put against [[http://www.scp-wiki.net/scp-682 SCP-682]]. [[http://www.scp-wiki.net/scp-173 SCP-173]] actually managed to "beat" SCP-682 but failed to kill it, and the staff have stopped repeats.

* UndergroundCity: [[http://www.scp-wiki.net/scp-110 SCP-110]], a city underneath a farm in New York that was displaced across time (although apparently it was already underground when it was built), and [[http://www.scp-wiki.net/scp-1678 SCP-1678]], a replica of VictorianLondon placed underneath the real London, and intended to serve as an bunker in case of catastrophe.
* UnequalRites: [[http://www.scp-wiki.net/scp-2164 SCP-2164]]-A and -B are a(n allegedly) Renaissance-era RitualMagic[=ian=] and a modern NewAge [[NewAgeRetroHippie Retro Hippie]] GranolaGirl (her food must be organic, gluten-free, and not altered genetically), respectively, who can alter reality within a radius of one meter with their rituals and potions. Oh, and they ''hate'' each other:

* UnexpectedlyRealMagic: [[http://scp-wiki.wikidot.com/scp-717 SCP-717 ("The Ambassador")]]. SCP-717 is the ruins of a home where a cult once worshipped. A group of teenagers tried to use a OuijaBoard in the basement and opened a gate to another dimension, which allowed a group of spirit entities to enter the basement and attack them.

** The Foundation was unmasqued by a rogue member during [[http://www.scp-wiki.net/scp-3455 SCP-3455]] in 1992. SCP-3455 is a "secret month"; at the end of the month, everything gets reset and everyone forgets what happened until next year, when SCP-3455 rolls around again. So the world is unmasqued for one month of the year and masqued for the other twelve.

** Deconstructed in [[http://www.scp-wiki.net/sandrewswann-s-proposal S Andrew Swann's Proposal of SCP-001]]; the Foundation tries to put together a "Grand Unified Theory" of [=SCPs=] (i.e. one big canon that ties everything together), but the myriad contradictions of reality (i.e. continuity) make them realize that there is some sort of "God" that's been doing what they believe is constant distortion of reality. [[spoiler:That "God" is "a bunch of horror writers", i.e. the authors of the SCP Wiki.]] In a potential future of said proposal, [[http://www.scp-wiki.net/scp-5500 they try again by force]], but [[NiceJobBreakingItHero accidentally (and quite literally) put too much torque on reality]], risking either its imminent collapse or a RealityIsOutToLunch situation.

* UnwillingRoboticisation: [[http://www.scp-wiki.net/scp-217 SCP-217]], a slow acting [[TheVirus virus]] that converts organic material into "organic metal". Extremely painful in advanced stages.
* UrbanFantasy: Deconstructed, particularly in regards to how the {{Masquerade}} is maintained. The [[http://www.scp-wiki.net/the-s-c-plastics-hub S&C Plastics canon]] plays the genre more-or-less straight.

* ValuesDissonance: InUniverse, one of the "explained" [=SCPs=] was considered explained because it only seemed unnatural to the people who originally wrote it, generations ago. The "phenomenon" was [[http://www.scp-wiki.net/scp-1851-ex some compulsion in black slaves to seek freedom]]. As values changed, the Foundation realized this was not an unexplained phenomenon, and gave it EX ("Explained") status.
* VeryLooselyBasedOnATrueStory: [[http://www.scp-wiki.net/scp-5312 SCP-5312]], which describes an 18th century woman named Virginia Croft who gave birth to a litter of rabbits, is inspired the real life case of [[https://en.wikipedia.org/wiki/Mary_Toft Mary Toft]], who in 1726 tricked doctors into believing she had done just that.
%%* VerySpecialEpisode: Parodied with [[http://www.scp-wiki.net/scp-why-are-you-reading-a-url-go-be-productive-j SCP-5200-J]].
* VideoGameCrueltyPotential: Invoked by [[http://www.scp-wiki.net/scp-1459 SCP-1459]], which allows the player to come up with any method on how the puppy dies as long as it wasn't used before.

** [[http://www.scp-wiki.net/scp-1348 1348]], for example, requires a ''thorough'' understanding of Abrahamic culture and mythology. Even the Site Director's name is significant.
** Or [[http://www.scp-wiki.net/scp-2280 2280]], which is plenty weird but makes more sense if you realize it's a creative reinterpretation of the Egyptian goddess [[http://en.wikipedia.org/wiki/Nut_(goddess) Nut]].
** [[http://www.scp-wiki.net/scp-3966 SCP-3966]] excepts the reader to understand neuroscience and [[spoiler:4-D geometry]] to understand the true nature of the anomaly.

* VoidBetweenTheWorlds: This is what [[http://www.scp-wiki.net/scp-3001 SCP-3001]] is classified as - a featureless, empty black void with an extremely low Hume level that allows objects to survive in it far longer than they would normally be able to.

** [[invoked]] [[http://www.scp-wiki.net/scp-1440 SCP-1440]], a man who destroys man-made objects [[spoiler: because he pissed off the Three Brothers of Death so badly they wanted to torture him forever by making him the ruin the human world he tried to save with the three death-defying objects he won from them (he initially just wanted a second chance at life but when he won he decided to ''[[WhatAnIdiot humiliate death]]'').]]
** [[http://www.scp-wiki.net/scp-032 SCP-032]], a (barely) DeceptivelyHumanRobot that destroys flora and fauna "un-influenced" by mankind [[spoiler: to further torture SCP-1440: it's an inhuman copy of his dead wife and it's only emotion is hatred towards her for being everything it isn't. The Three Brothers want to ruin his memories so he'll let the world crumble in despair as part of his punishment.]]

** [[http://www.scp-wiki.net/scp-811 SCP-811]] (a.k.a. Aé):

** The Foundation as a whole becomes this after their FaceHeelTurn from having (possibly) GoneMadFromTheRevelation in [[http://www.scp-wiki.net/scp-5000 SCP-5000]]. They still ''look'' human, but most definitely aren't. Notably, even [[TheGrimReaper the Three Brothers Death]] can't recognize them as humans anymore.
* WeHaveReserves: The general treatment of Class D personnel. Especially evident with testing for [[http://www.scp-wiki.net/scp-504 SCP-504]], where it was discovered that recordings worked just as well as people, yet whoever was overseeing the test continued using people, apparently just because he didn't like them (although it's at least noted that he would be reprimanded for it).

* WeaksauceWeakness: [[http://www.scp-wiki.net/decomm:scp-723-d SCP-723-D]], a boring NighInvulnerable man, managed to survive a scad of excessively lethal tactics, and in the end succumbing to [[spoiler:a peanut allergy.]]

** [[http://www.scp-wiki.net/scp-1812 SCP-1812]], an extra moon that you won't see unless it's pointed out to you. Once that happens, you'll be affected by it, including improved night vision from the reflected light, and drowning in nonexistent tides. The Foundation doesn't even know if the thing's ''real''.
** [[http://www.scp-wiki.net/scp-4220 SCP-4220]], a.k.a. the Earth's Moon, is apparently ''hollow,'' and within it is a massive facility conducting office work for the containment of an EldritchAbomination.
* WeirdWeather: [[http://www.scp-wiki.net/scp-2049 SCP-2049]] is an anomalous weather report broadcast which describes and is followed by a variety of unusual weather. Examples include fog made of cotton candy, radiation storms, [[ExactlyWhatItSaysOnTheTin weather balloon downpours]], and a low-speed [[RazorWind monofilament tornado]].

** The Manna Charitable Foundation's stated goal is to relieve poverty in the least developed areas of the world using [=SCPs=]. A noble goal, but given that they ignore the side effects they can do harm as much as good. For example, [[http://www.scp-wiki.net/scp-1176 widespread distribution of a high-calorie honey-like substance]]... that kills anyone not of AB+ blood type.

** [[http://www.scp-wiki.net/scp-1892 SCP-1892]], a "haunted" doctor's chair that just wants to cure its "patients" with 50's-era prescriptions. [[spoiler: Unfortunately, it's a psychiatrist's chair, and the 50's had a thing for lobotomies...]]

* WhatCouldPossiblyGoWrong: [[http://www.scp-wiki.net/scp-048-j SCP-048-J]]'s ''second'' trigger phrase. The first was "T█████ c██'█ g██ a██ w████" ([[FromBadToWorse they do]]).

* WhatYearIsThis: Used as part of the containment improvement procedures for [[http://www.scpwiki.com/scp-2718 SCP-2718]]. [[spoiler:Whenever a workstation is found to have accessed SCP-2718, a specialized engineer is dispatched to further reduce the likelihood that someone will come across the article, which cannot be deleted nor can it be access-restricted through conventional means. The engineer then has to take a heavy-duty amnestic, and if they are able to recall the current year or name the current [[UsefulNotes/ThePresident U.S. President]], it means either the amnestic didn't work or they didn't take it, and they are to be terminated. The idea is to make sure that [[TheseAreThingsManWasNotMeantToKnow no one knows about SCP-2718]], due to it being an [[GoMadFromTheRevelation extremely dangerous cognitohazard]].]]

** Inverted. If something is lethal, they will at least suggest trying to kill [[http://www.scp-wiki.net/scp-682 SCP-682]] with it.
** Played straight with everything the Foundation keeps stuffing into [[http://www.scp-wiki.net/scp-914 914]].
** They will use [[http://www.scp-wiki.net/scp-447 SCP-447's]] slime on everything, as long as it doesn't involve [[RunningGag dead bodies]].

** While they don't seem to be ''deliberately'' rebelling, [[http://www.scp-wiki.net/scp-2815 SCP-2815]] is notable for being the first truly ''benign'' [[ReligionOfEvil Sarkic cult]] community ever discovered: the cannibalism is only for funerals, their flaying ritual is done on fruit, and most amazingly of all, [[spoiler: no one died or even went insane in the exploration log!]] To the consternation of more concerned members of the Foundation (they ''are'' still inbred[[note]](though thanks to their mastery of [[LovecraftianSuperpower Sarkic magicks,]] Sarkic cultists can inbreed without the threat of genetic deformities and other issues)[[/note]] cannibalistic cultists who are ''tricking people into eating human flesh fruit'' and accepting anomalous blood and organs via the Manna Charitable Foundation - which, given [[GoneHorriblyWrong Manna's track record...]]), not even ''[[WellIntentionedExtremist the Global Occult Coalition]]'' wanted to neutralize them as there was simply no definitive proof they or their products were actively harmful.
** There's also the small Sarkic town of [[http://www.scp-wiki.net/sarkic-case-study-01-the-vas-n-a-of-sarvi Sarvi]] in northern Finland, who are pretty benevolent (if rather insular), with some members even calling out their more extremist brethren as "rapists and murderers."
** Yet ''another'' Sarkic example appears with [[http://www.scp-wiki.net/scp-4036 "The Adytite Republic of Polynesia"]], a small theocratic republic that the Foundation has [[HiddenElfVillage almost completely cut off from the rest of the world]]. Despite their worship of Sarkicism (the American filibuster who originally founded the Republic became enamored with the cult after GoingNative, and even after a simultaneous Foundation-global alliance and interval revolution ousted him, it's never stopped being the state religion), the conducted interviews show that the residents of the Republic are pretty average folk with just as many flaws and virtues as anyone found anywhere else in the world, and the only reason why a not-insignificant number of them hate the Foundation is their desire for independence.

** [[http://www.scp-wiki.net/scp-157-arc SCP-157-ARC]] was the bullet that shot Kennedy... and Franz Ferdinand... and probably lots of other people...
** [[http://www.scp-wiki.net/scp-3780 SCP-3780]] is the Foundation's constant thwarting of time travelers trying to prevent Lee Harvey Oswald from carrying out the assassination.
* WhosOnFirst: [[http://www.scp-wiki.net/scp-safe-j SCP-SAFE-J]]. It's a series of three safes (a Safe safe, a Euclid safe, and a Keter safe). The Safe safe is always safe, the Euclid safe is safe except when near the Keter safe, and the Keter safe is never safe (though it is a safe). And don't get started on the researchers observing them...

** [[http://www.scp-wiki.net/scp-138 SCP-138]] and [[http://www.scp-wiki.net/scp-963 Dr. Bright]]. Also, implied by [[http://www.scp-wiki.net/scp-1030 SCP-1030's]] statement about its origin.
** [[http://www.scp-wiki.net/scp-1504 SCP-1504]]: He's immortal, wants to die, [[spoiler: can't be seen, heard, or felt "properly": no one sees him leave the interview room to "borrow" a guard's gun to shoot himself; yelling and screaming is "reedited" into mild answers; when he punches the researcher interviewing him, the researcher wonders why his nose started bleeding]], and in his quest to die [[spoiler: tried to murder an entire site's staff, caused a site-wide containment breach that necessitated a ''nuclear detonation'', '''''and no one knows if he's dead or alive''''']].
** [[http://www.scp-wiki.net/scp-2039 SCP-2039]] are a pair of FeudingFamilies who, when agitated, attack each other with anomalous weapons until one side's elder is dead. The next day everyone revives with no memory of the attack save the two elders, and the one who started it all isn't happy about it:

* WickedWitch: [[http://www.scp-wiki.net/scp-5294 SCP-5294]], an entity physically resembling an old woman, with a long tail similar to that of a rat's, which ends in a large eyeball. Considering she used this tail to steal and cook young babies in their homes back in the nineteenth century, it's safe to say she's as wicked as they come.
* WilyWalrus: [[http://www.scp-wiki.net/scp-2424 SCP-2424]] is a missile-shooting walrus who seems to be a boss transported into the real world from a video game;.
* WindsOfDestinyChange: [[http://www.scp-wiki.net/scp-181 SCP-181]], discovered as a D-class who kept surviving experiments with Keter-class anomalies by seemingly impossible good luck. Further experiments confirmed that he could influence probability. Then it was found that his influence could cause [DATA EXPUNGED], so now he's in solitary confinement.

** [[http://www.scp-wiki.net/scp-3185 SCP-3185]] concerns the actions of the Public Domain Protection Service, an organization from the future that punishes anyone involved in copyright extension. The author isn't a fan of copyright extension and outright called the article [[http://scp-wiki.wikidot.com/forum/t-5093463/scp-3185#post-3694453 "a hate letter"]].
** [[http://www.scp-wiki.net/scp-3922 SCP-3922]] acts as a [[MoralGuardians morality filter]] for movies and TV shows, by inserting soldiers from another universe to punish the bad guys. [[http://www.scp-wiki.net/forum/t-5668086/scp-3922-extended-test-logs#post-3772768 The author admits]] that half the reason he wrote the article is because he really, ''really'' wanted to see [[KarmaHoudini the Coachman]] from ''{{WesternAnimation/Pinocchio}}'' get his just desserts.
** Happens in-universe in [[http://www.scp-wiki.net/scp-3143 SCP-3143]], when Dr. Thaddeus Thaum accuses Murphy Law of being a wish fulfillment character.

* WombHorror: [[http://www.scp-wiki.net/scp-231 SCP-231-7]] is the last survivor of seven pregnant women extracted from an ApocalypseCult. Her predecessors underwent progressively more catastrophic [[NothingIsScarier [DATA EXPUNGED][==]]] upon dying or giving birth, such that the Foundation projects that #7 could kick off the Apocalypse. Whatever procedure they use to keep her from delivering, even members of an organization ConditionedToAcceptHorror routinely volunteer to have their memories wiped of the experience.
* WordSaladHorror: Many [=SCPs=] are made scarier by the eerie nonsense they spout off, as with [[http://www.scp-wiki.net/scp-1981 SCP-1981]] and [[http://www.scp-wiki.net/scp-058 SCP-058]].
* TheWorldAsMyth: [[http://www.scp-wiki.net/scp-2591 SCP-2591]] is from the world of an unfinished opera.

** [[http://www.scp-wiki.net/scp-1249 SCP-1849]]. This trope and the similar WanderingJew are cited in the comments, plus a reference to ''Manga/FrankenFran'', which also had a "Wandering-Jew-Made-Of-Vermin" story. There's also this:

** Replace "worm" with "words" and you have [[http://www.scp-wiki.net/scp-1516 SCP-1516]], who's also hinted to be [[spoiler: a fourth-wall-breaker, what with his talk of the god(s) who wrote him and read him]].
* WorthyOpponent: [[http://www.scp-wiki.net/scp-1638 SCP-1638]] is the "memorial" of a sound/music-using [[MadArtist anomalous artist]][[note]]Not an AWCY? artist[[/note]] to the Foundation researcher who contained his "pieces".

* WouldHurtAChild: [[http://www.scp-wiki.net/scp-106 SCP-106]], while not exactly picky, is mentioned to preferentially target victims in the 10-25 age range.
** The entry for [[http://www.scp-wiki.net/scp-1018 SCP-1018]] heavily implies that [[MadArtist Are We Cool Yet?]] kidnapped and/or murdered six children to create anomalous statues for the purpose of freaking out wealthy socialites.

** [[http://www.scp-wiki.net/scp-2085 SCP-2085]], the Black Rabbit Company (formerly "Space Wizard and the Commando CatGirl[=s=]!"), a group of fun-loving adventurers with cybernetic and genetic enhancements plus all sorts of anomalous tricks. Naturally the Foundation couldn't let them run wild so they're trapped forever.

** The trope works [[SillyRabbitCynicismIsForLosers both ways]] in this case, however: ThePowerOfFriendship is pending classification as a Thaumiel class SCP following the events of [[http://www.scp-wiki.net/stealingsolidarityphase1 Stealing Solidarity]]
** Two of the three agents first sent after [[http://www.scp-wiki.net/scp-953 SCP-953]] were Japanese and mistook her for a lovable {{Kitsune}}. The third and sole surviving agent was Korean and familiar the gumiho, with [[GenreSavvy rather more bloodcurdling folklore about fox women]].
** The Site Director in charge of securing [[http://www.scp-wiki.net/scp-2310 SCP-2310]] got hung up on the idea that its inhabitants were a cult; they actually had their identities replaced with one woman's (at one point they saw "a man dressed in red robes" ''which turned out to be women's nightwear''). Unfortunately about a dozen armed Foundation personnel charged in before they figured it out, fortunately the woman they were replaced with was unfamiliar with guns, unfortunately they were all effectively killed as there is currently no way to bring back their original personalities.
** [[http://www.scp-wiki.net/scp-2662 SCP-2662]], a mild-mannered (Late Bloomer, according to his author) teenage {{cosmic horror}} who is not mature enough to deal with the more... squicky aspects of cosmic horror-worship, is under the impression that when he can control his powers better he can just bust out of his containment site. Considering the only people he can influence all work for the Foundation, they know better even in their addled state.

* {{Yandere}}: [[http://www.scp-wiki.net/scp-962 SCP-962]] is one [[spoiler: FOR THE ENTIRE HUMAN RACE]].
* YearInsideHourOutside: [[http://www.scp-wiki.net/scp-1859 SCP-1859]] deals with several consequences of this.

* YouAreNumberSix: Every humanoid SCP is referred to by their designated number. Most of them don't mind this, or at least demand a nickname. [[BadPowersBadPeople "Vector", in particular,]] kept demanding to be treated like some Marvel villain. [[http://www.scp-wiki.net/scp-811 SCP-811]] is allowed to be called Aé because it "streamlines the interviewing" and it sounds like her ID number (eight-eleven).
** However, several [=SCPs=] have "official" names, either because they're sort of like pets ([[http://www.scp-wiki.net/scp-529 "Josie"]], [[http://www.scp-wiki.net/scp-530 "Carl"]], and [[http://www.scp-wiki.net/scp-524 "Walter"]]), they are sentient and willing to give their names, ([[http://www.scp-wiki.net/scp-105 Iris Thompson]] and [[http://www.scp-wiki.net/scp-1156 Wellington G. Wonderhorse]]).
** The titles on the SCP series pages do not count as names unless the work itself does some sort of TitleDrop with names. They are explicitly stated as being not in-universe by the [[http://www.scp-wiki.net/how-to-write-an-scp writing guide]].

** Averted in the case of [[http://www.scp-wiki.net/scp-1467 SCP-1467]], who ''has'' to be called "Mr. Smith" to reinforce his tenuous existence within reality. But ''only'' in his actual presence.

* YouBastard: [[http://www.scp-wiki.net/scp-1459 SCP-1459]], a game where you ''murder adorable dogs for cookies in your own sadistic way!'' Creative and/or sadistic deaths get more cookies. After playing, you're rewarded with "Yeah, you're totally going to hell for this. Play again?". Brought to you by your friends at Y.W.T.G.T.H.F.T.[[note]]Either "Yeah We're Totally Going To Hell For This" or "You Will Totally Go To Hell For This."[[/note]]

** [[http://www.scp-wiki.net/scp-031 SCP-031]], which appears to each viewer as someone in their past that they had a romantic relationship with.
** [[http://www.scp-wiki.net/scp-055 SCP-055]], the self-keeping secret. Everything about it is unknown, ''except that you can't know anything about it''. The SCP will erase any memories that pertain to it from the minds of intelligent humans who observe it. Its very image, copied onto photographs or drawings, will also become impossible to remember or describe within seconds of looking at it. Any scientific readings about it will be forgotten immediately after viewing them. There's only one hitch. It will not prevent you from remembering what it is ''not'', provided you can be reminded you ever looked at it at all. Given, well, ''forever,'' you could work out what it was by eliminating ''everything'' else. It's considered Keter-class (as a general rule, that means "stuff that could end the world" or "682") because [[NothingIsScarier it's just that unknown]]. If it was something so lethal the {{Eldritch Abomination}}s look like SantaClaus by comparison, nobody would remember!
** SCP-055 is only one of many [[http://www.scp-wiki.net/antimemetics-division-hub anti-memes]], things or ideas that self-censor itself out of knowledge. Something that erases your memory of what it is, as it turns out, is ''the weakest kind of anti-meme''. Far more dangerous are things that wipe you and everyone connected to you out of existence the moment you know its true form, like [[http://www.scp-wiki.net/scp-3125 SCP-3125]][[note]]5 5 5 5 5 వ[[/note]].
* YouCantFightFate / BecauseDestinySaysSo: [[http://www.scp-wiki.net/scp-1271 SCP-1271]] teleports children from around the world to play a game of kickball. Those players who have been found almost always have a destiny based on their positions; for instance the red team's second baseman/second kicker will die before age 18 and the blue team's second baseman/second kicker becomes head of state or a high-ranking politician. When one man tries to resist his fate of [[spoiler: becoming addicted to drugs by age 25 and dying before age 27 ''everyone around him becomes a drug pusher''. This includes his own parents, his teachers, anti-drug program advocates, and the Foundation doctor who was studying him. Unfortunately the doctor succeeded in injecting him, the subject was terminated, and the Foundation discovered that SCP-1271 can create mind-altering brain tumors.]]
* YouDirtyRat: [[http://www.scp-wiki.net/scp-731 SCP-731]] is a manhole cover. Rats are involved too. [[http://www.scp-wiki.net/scp-798 SCP-798]] is more lonely but no less weird.
* YouKeepUsingThatWord: A pair of modern-day Are We Cool Yet? artists try to appeal to an older artist by calling the modern EU "fascist". Since the older artist lived through [[UsefulNotes/WorldWarII actual fascism]] he doesn't appreciate the AWCY guys' ignorance/hyperbole and [[spoiler: entombs them (and himself) in his [[http://www.scp-wiki.net/scp-1803 "living" collage]]]].
* YourMimeMakesItReal: [[http://www.scp-wiki.net/scp-5040-j SCP-5040-J]] are two hostile gangs of mimes with this ability.

%%* ZeppelinsFromAnotherWorld: [[http://www.scp-wiki.net/scp-1835 SCP-1835]] and [[http://www.scp-wiki.net/scp-5913 SCP-5913]].

** [[http://www.scp-wiki.net/scp-008 SCP-008]] is TheVirus in this scenario (it's luckily been avoided so far).
** [[http://www.scp-wiki.net/scp-1372 SCP-1372]] appears to be the edge of the world... and anyone who goes over it comes back as ''pirate zombies'' trying to convince others to go over the edge with them.

->''[[http://www.scp-wiki.net/scp-3999 and that's all i wrote.]]''

* {{Troll}} SCP-1459 comes across as this, espically in its [[https://scp-wiki.wikidot.com/scp-1459-extended-testing-log testing log.]], doing things such as seemingly deliberately misinterpreting prompts (in particular see Doctor Margin's request starting from "current events") and appearing to let a Agent Foxx pet one of the dogs released, but shutting the door before they are actually able to.

** [[https://scp-wiki.wikidot.com/scp-5740 Dado]] has definitely not noticed that donuts from their stores cause cops to shit out pigs, and it is absolutely not any kind of political statement.

*** Also, the ad for the restaurants contains statements such as "donut not dangerous" and "definitely not trap".

* TheTimeOfMyths: [[https://scp-wiki.wikidot.com/project-paragon-hub Project PARAGON]] is a Foundation subdivision dedicated to studying an era of history where great empires battled each other for dominance with magic, humanity shared the earth with the fae, and monsters were commonplace. The period ended about 399,900 years BCE, and the Foundation have only recently begun uncovering the remnants.

** PlayedForLaughs in the SCP Tale, ''[[https://scp-wiki.wikidot.com/everyone-knows Everyone Knows]]'', as it turned out that over the years, the Masquerade had grown so big, everyone on the planet (save one guy) was secretly aware of the anomalous in one way or another (The SCP Foundation alone employed almost 3.5 billion people). The Masquerade is formally dissolved in a televised broadcast, and upon watching it, the aforementioned one guy claims he knew all along.

** Yet ''another'' Sarkic example appears with [[http://www.scp-wiki.net/scp-4036 "The Adytite Republic of Polynesia"]], a small theocratic republic that the Foundation has [[HiddenElfVillage almost completely cut off from the rest of the world]]. Despite their worship of Sarkicism (the American filibuster who originally founded the Republic became enamored with the cult after GoingNative, and even after a simultaneous Foundation-global alliance and interval revolution ousted him, it's never stopped being the state religion), the conducted interviews show that the residents of the Republic are pretty average folk with [[NotSoDifferent just as many flaws and virtues as anyone found anywhere else in the world]], and the only reason why a not-insignificant number of them hate the Foundation is their desire for independence.

* SlidingScaleOfSillinessVersusSeriousness: [[invoked]] The wiki itself slowly slid from a general silly mood to a more serious mood. Early on when things are still messy, articles can often have dead-serious (sometimes ''so'' dark and serious they just seem silly again) descriptions, [[MoodWhiplash then end with a silly addendum]], making things seem rather silly on the grand scale. The ShooOutTheClowns mentioned above purged most of the articles that are deemed "too silly", and newer, more serious writers turned the wiki down the serious path. Nowadays, the wiki as a whole is pretty serious, though individual articles/canons may still have some silly themes, but tend to aim away from being potentially {{Narm}}-inducing like some of the early works and are instead treated in a serious way. That being said, there are still a high number of strange or funny articles, especially among the newer series, though these tend to avoid {{Narm}} by instead more emphasizing the {{Surreal Humor}} of dealing with bizarre things like [[http://www.scp-wiki.net/scp-504 SCP-504]][[note]]a species of tomato [[ProducePelting that violently hurl themselves at anything cracking a bad joke within earshot]][[/note]], [[http://www.scp-wiki.net/scp-1472 SCP-1472]][[note]]an anomalous strip club which had one act consist of ''Velociraptors'' in {{Meido}} costumes[[/note]], [[http://www.scp-wiki.net/scp-2020 SCP-2020]][[note]]an alien coming up with random sci-fi story ideas[[/note]], [[http://www.scp-wiki.net/scp-3922 SCP-3922]][[note]]a device that causes super-powered police to bust into any televised work to arrest lawbreakers[[/note]], [[http://www.scp-wiki.net/scp-4950 SCP-4950]][[note]]an ApocalypseCult almost succeeding in using both ''VideoGame/{{Fortnite}}'' and an ''Toys/{{amiibo}}'' to summon their DestroyerDeity[[/note]], and [[http://www.scp-wiki.net/scp-5983 SCP-5983]][[note]]a bizarrely symbiotic connection between explosions within a small county in Wisconsin & the efficiency of the New York City Subway[[/note]] - all of which is almost always described in [[TheComicallySerious an unflappably scientific demeanor]].

* SpiritualAntithesis: Both [[http://www.scp-wiki.net/twistedgears-kaktus-proposal TwistedGears-Kaktus' SCP-001 Proposal]] and [[http://www.scp-wiki.net/scp-4882 SCP-4882]] deal with the Broken God being rebuilt. However, the former is mechanical, built by a small group of followers, and destroyed by physical forces. Meanwhile, the latter is electronic, built by technological society as a whole, and kept at bay by diplomacy. And where the former ends on a denouement, SCP-4882 ends on a cliffhanger.

* SenselessSacrifice: In [[http://www.scpwiki.com/shaggydredlocks-proposal SCP-001: S.D. Locke's Proposal]]. A D-class agrees to try drawing instances of SCP-001-A away from the others, on the grounds that he gets a gun and one bullet for it. He kills himself, with him and the researches hoping that it will spare him from becoming another one of those blob monsters...but not only do they get ahold of him and drag him out into [[spoiler:the sunlight]], he [[CameBackWrong comes back and becomes yet another one of them]]. About 3 1/2 years later, [[spoiler:Dr. Igotta does the same, using pills to quietly end herself, hoping that she won't draw the attention of the ever-growing sun blobs (the alternative being a gun, which she notes would draw their attention). Unfortunately, [[TheFourthWallWillNotProtectYou the reader]] finds that she's become another one of them.]]

** [[http://www.scp-wiki.net/scp-4220 SCP-4220]] is largely focused on both an analysis of American occultism during the 1950s and 1960s and the lives of Creator/{{Aleister Crowley}}, Jack Parsons, and L. Ron Hubbard. Aside from the obvious breaks from history (i.e., Crowley and Parsons were never forced by the government into using {{Magitek}} to get to the Moon before the Soviets did in our world), all of the details given to both the lives of the three aforementioned men and the subculture of mid-20th century American occultism are real.

* SleepWalking: [[http://scp-wiki.net/scp-5586 SCP-5586]], a sleepwalker who has been known to turn up in a variety of odd locations, including the Queen's bedroom, the Oval Office (where he threw his slipper at Presidenr Nixon), and the ''surface of the Moon''.

** [[http://www.scp-wiki.net/scp-239 SCP-239]] is a deconstruction of ''[[LightNovel/HaruhiSuzumiya Haruhi Suzumiya]]''-style Reality Warpers, showing just how dangerous a child would be when given these powers. Instead of being a super-powerful LittleMissAlmighty, she is, whilst non-malicious, a confused, frightened little girl with potentially world-ending powers, which she can neither understand nor control. It gets to the point where ''keeping her in a coma'' is the safest way to contain her.

** SCP-076-1, amongst others, is one such can. It contained SCP-076-2, but it was easily unsealed (it was just a stone coffin), and when SCP-076-2 started working ''for'' the Foundation, it became little more than 076-2's respawn point. Later played straight during the great MarySue purge — 076-2 [[spoiler:was retconned into being completely AxCrazy after all, and after they ran out of things for him to do, he started killing all humans on sight. They had to detonate a nuclear bomb and entomb 076-1 under the bedrock under the ocean]].

** Happened in several stages, but began when one of the writers became concerned about the wiki moving away from its original creepypasta origins. He came up with a story where his fictional counterpart tries to take down a reality warper who seemed to have become popular with readers simply because she was a cute little girl. This had the ''opposite'' effect, as it led to decommissions which were 'canon' purges of badly designed, [[MarySue Mary Suish]] [=SCPs=]. Writers competed with each other over who could pull off the most over-the-top decommissions.

** Also, [[http://www.scp-wiki.net/chowderclef "Chowderclef"]] is an official {{Retcon}} of all of Dr. Clef's quirky escapades… sort of. [[WordOfGod Clef (the writer)]] ultimately decided to be ambiguous about it and let readers decide for themselves whether or not the escapades still count.

* SturgeonsLaw: The [[http://scp-wiki.wikidot.com/history-of-the-universe-hub "History Of The Universe"]] recap on the website history notes that this is in full force [[ColbertBump every time there's an uptick of newcomers]]: "Numerous new SCP articles were being posted every day, and many of them were extremely poor."

** [[http://www.scp-wiki.net/scp-2662 SCP-2662]], a mild-mannered (Late Bloomer, according to his author) teenage {{cosmic horror}} who is not mature enough to deal with the more... ''{{squick}}y'' aspects of cosmic horror-worship, is under the impression that when he can control his powers better he can just bust out of his containment site. Considering the only people he can influence all work for the Foundation, they know better even in their addled state.

* SelkiesAndWereSeals: [[http://www.scp-wiki.net/scp-5561 SCP-5561]] contains a very dark variation on this trope.
** [[http://www.scp-wiki.net/scp-3477 Harold Holt]] claims to have become immortal by donning a cloak made of sealion skin.

* ZeppelinsFromAnotherWorld: [[http://www.scp-wiki.net/scp-1835 SCP-1835]] and [[http://www.scp-wiki.net/scp-5913 SCP-5913]].

* SelkiesAndWereSeals: [[http://www.scp-wiki.net/scp-3477 Harold Holt]] claims to have become immortal by donning a cloak made of sealion skin.

%%** [[http://www.scp-wiki.net/scp-5561 SCP-5561]] contains a very dark variation on this trope.

* YourMom: As the unlucky D-Class from orientation found out, the Junior Researcher doesn't like having his mother insulted.
