History SCPFoundation / TropesEToM

!!''Wiki/SCPFoundation'' provides examples of the following tropes:

* EldritchLocation: Lots of those too. Some noteworthy examples include [[https://scp-wiki.wikidot.com/three-portlands-hub Three Portlands]] (a magical and semi-autonomous city-state looked after by the UIU), [[https://scp-wiki.wikidot.com/scp-2922 Corbenic]] (a multiverse-spanning afterlife home to forgotten gods and monsters), Wiki/TheWanderersLibrary (a PortalCrossroadWorld and magical library used as the primary base of [[LibertyOverProsperity the Serpent's Hand]]), [[HellOfAHeaven Adytum]] (the extra-dimensional kingdom of Grand Karcist Ion and "Heaven" of the Sarkic Cults), and [[https://scp-wiki.wikidot.com/scp-2264 Alagadda]] (another PortalCrossroadWorld ruled over by [[https://scp-wiki.wikidot.com/scp-701 the Hanged King]]).

** [[https://scp-wiki.wikidot.com/scp-1176 SCP-1176]] is a sarcophagus that produces an extremely nourishing honey-like substance. This being the Wiki/SCPFoundation universe, it's only ''after'' widespread distribution that they discovered it only works on those of the AB+ blood type, killing all others.

* EverythingIsOnline: Actively [[DefiedTrope defied]] in the containment procedures of any Artificial Intelligence-based SCP.
* EverythingsBetterWithDinosaurs: [[https://scp-wiki.wikidot.com/scp-1905 SCP-1905]], [[https://scp-wiki.wikidot.com/scp-1265 SCP-1265]] and [[https://scp-wiki.wikidot.com/scp-250 SCP-250]].

* EvilPhone: [[https://scp-wiki.wikidot.com/scp-145 SCP-145]] and [[https://scp-wiki.wikidot.com/scp-519 SCP-519]].

* ExactWords: The Foundation universe, or at least the version described in the [[https://scp-wiki.wikidot.com/wrong-proposal Wrong Proposal]], operates on an EquivalentExchange theory which states that for every concept deemed normal, an anomalous analogue exists as well. For example, the concept of math is countered by SCP-033, the missing number, and the concept of chemistry is countered by SCP-2046, an extended periodic table that converts surrounding matter into elements beyond oganesson that are mostly incompatible with reality. When the Foundation explains an anomaly in the new world and finds no known counterpart, they think the theory has failed them at laast... except since the theory describes a natural law, the anomalous counterpart of the theory would be to simply contradict it.

* ExtremeOmnivore: Several [=SCPs=] are this.

* ElementalShapeshifter: One of the [=SCPs=] could turn into earth, fire, water, wind, and lightning.

* ManEatingPlant: [[https://scp-wiki.wikidot.com/scp-506 SCP-506]].
** [[https://scp-wiki.wikidot.com/scp-1001 SCP-1001]] as well.

* MachineWorship: The Church of the Broken God, one of the organisations that opposes the Foundation.
** [[https://scp-wiki.wikidot.com/scp-882 SCP-882]] [[https://scp-wiki.wikidot.com/interview-882-1 before]] its apprehension by the Foundation.
* MadArtist:
** Are We Cool Yet? is an entire collective of these. Ever wonder what it's like to give a bunch of sociopathic art students magic? [[BodyHorror Now you know.]]
** Gamers Against Weed is a [[LighterAndSofter sillier and safer]] (relatively; their "pranks" may be irritating, but ''never'' fatal) splinter of AWCY? [[spoiler:which may have been founded by a former AWCY? member going by the screen name of "bluntfiend" who was horrified when "The Minotaur" killed his friend]].
** An unrelated artifact is [[https://scp-wiki.wikidot.com/scp-804 SCP-804]], an art installation that could destroy anything man-made on the planet (including [[BodyHorror humans]], but at a much slower rate). Why did the artists create such a thing? [[spoiler:[[OmnicidalManiac They simply wanted to do it.]]]]
* MadnessMantra: [[https://scp-wiki.wikidot.com/scp-2316 SCP-2316]]: You do not recognize the bodies in the water. [[spoiler:Can't you hear them?]]

* {{Magitek}}: The Global Occult Coalition uses it in addition to normal technology. [[https://scp-wiki.wikidot.com/goc-supplemental-arad Aetheric Resonance Imagers]] are one example.

* MakesJustAsMuchSenseInContext: [[spoiler:Argent Simian]].

* MakesJustAsMuchSenseInContext: [[spoiler:Argent Simian]]

* MagicalNativeAmerican: [[http://www.scp-wiki.net/scp-992 SCP-992 ("Gaia's Emissary")]]. SCP-992 is a male Australian Aborigine who claims to be 57-71 years old but hasn't aged in the 65 years that he's been contained by the Foundation. He appears to be able to control the weather and talk to plants.

* TheLostWoods: [[https://scp-wiki.wikidot.com/scp-416 SCP-416]] is an infinite one that you can't leave on foot. [[https://scp-wiki.wikidot.com/scp-1660 SCP-1660]] is a portal to one that is enclosed by a barrier of an unknown material. '''[[https://scp-wiki.wikidot.com/taboo The article that you can't call SCP-4000]]''' is populated by TheFairFolk and has a disturbing number of rules you must follow in order to exit safely.

** Gamers Against Weed: "[[GratuitousLatin Sic semper]] [[FourTwentyBlazeIt cannabis]]."

** Shark Punching Center: "To [[TheWitchHunter Seek]] and [[EnhancedPunch Punch]] [[FiendishFish Cartilage]]."

** [=TotleighSoft=]: [[WordSaladHumor "Because]] [[SuddenlyShouting COMPUTERS!"]][[{{Tradesnark}} ™]]

** [[invoked]] The site itself goes through [[CyclicTrope periods]] of this and DarkerAndEdgier, as the balance shifts between odd and whimsical [=SCPs=] and NightmareFuel entries. In particular, one phase of the site's canon is viewed with [[NostalgiaFilter a mix of nostalgia]] [[OldShame and eyerolling]], and has come to be collectively known as "lolFoundation." Tales in this arc are typically taken as a combination of RashomonStyle soft canon [[SelfServingMemory exaggerated or invented in the aftermath]], and certain [=SCPs=] causing mental breakdowns and distortions of the laws of physics. Everyone does seem to agree, however, the destruction of Site 19 was where it all got a little out of hand, in-universe and out.

*** Furthermore, SCP-4231 also does this in terms of [[NoodleIncident Procedure 110-Montauk]] from [[https://scp-wiki.wikidot.com/scp-231 SCP-231]]. Here, it essentially states that the true horror of Montauk isn't the brutality that they force upon [[WouldHurtAChild an innocent child]], but that [[spoiler:the suffering ''also'' changes the one who inflicts it upon her, and anyone involved in Procedure 110-Montauk is [[ShellShockedVeteran forever traumatized (however subtly)]] [[MyGodWhatHaveIDone by it for the rest of their days]]. Essentially, it's implied that the latter is the '''true''' source of power that the Scarlet King gains from Montauk.]]

* TheFairFolk:

*** Furthermore, SCP-4231 also does this in terms of [[NothingIsScarier Procedure 110-Montauk]] from [[https://scp-wiki.wikidot.com/scp-231 SCP-231]].

Essentially, it's implied that the latter is the '''true''' source of power that the Scarlet King gains from Montauk.]]

--->''Log of F███████ R███████'': The captain… was only after a fashion onboard. The same goes for the crew… they are gone now, [[KillItWithFire the flames took them.]] Today is mostly a blur. All I know is that the moment I heard the men onboard that ship speak, [[TheseAreThingsManWasNotMeantToKnow I didn't want to understand their far-off words.]] [...] Forgive me, Captain, but I no longer want to know what you saw beyond the edge of the Earth.

** [[https://scp-wiki.wikidot.com/scp-5031 SCP-5031]] is a more serious {{deconstruction}} of the site's change in tone, depicting how a typical "murder monster" from the site's earliest years begins to grow and thrive when given proper treatment under the Foundation's newer management.

--> SCP-682 must be destroyed as soon as possible.

* FoulBallPit:
** SCP-1904 is a tube playground located at an unnamed fast food restaurant. It will periodically bleed, release amniotic fluids, and expel beings resembling human embryos with congenital deformities. Humans who enter the tubes are also [[WasOnceAMan transformed into these creatures.]] The [[Website/{{Bogleech}} author]] based the SCP on his own childhood experience with unpleasantly sticky playground tubes.
** [[https://scp-wiki.wikidot.com/scp-6059 SCP-6059]] is a an entity discovered at a Chuck E. Cheese ball pit, identifying itself as "Botulae, [[OddJobGods God of the Pit]]". It has an amorphous body composed of "plastic, vomit, pizza sauce, and trace amounts of feces and urine."

* FormulaicMagic: [[https://scp-wiki.wikidot.com/scp-033 SCP-033]].
* FountainOfYouth: [[https://scp-wiki.wikidot.com/scp-006 SCP-006]].

* FaceHeelTurn: The Foundation as a whole undergoes one of these after discovering [[ThingsManWasNotMeantToKnow something horrible]] in [[https://scp-wiki.wikidot.com/scp-5000 SCP-5000]].

* GreaterScopeVillain: [[SatanicArchetype The Scarlet King]] is by far the most recurrent evil in the mythos, but the Foundation hasn't encountered him directly. And according to SCP-4231, [[spoiler:he's also indirectly responsible for Clef's insanity.]]

* EverythingsBetterWithMonkeys: An odd side-effect of [[https://scp-wiki.wikidot.com/scp-2820 SCP-2820]]:
-->Notably, eyewitness testimonies in the aftermath of the target's death consistently mention the appearance of a chimpanzee in a trench coat. Video recordings and forensic investigations into the aftermath of SCP-2820 kills indicate that the chimpanzee does not actually exist; it is purely a perceptual phenomenon resulting from the aforementioned [[ButterflyOfDoom nonlinear system]] [of assassinating anomalies].
** Everything [[https://scp-wiki.wikidot.com/system:page-tags/tag/simian#pages here]] (SCP-2820 doesn't appear probably because the chimp isn't real).

* MohsScaleOfScienceFictionHardness: Despite being an entire universe about things that go against scientific rules, everyone treats everything with good scientific hardness and bases the magical things in plausible physics terms. It is best described as what happens when you have Speculative Science themes and descriptions in a Science In Genre Only setting by lampshading all the different unscientific things.

* HumanoidAbomination: Some of the upper ranking researchers are this due to exposure to [=SCPs=]. For instance, Dr. Bright is more or less a [[OurLichesAreDifferent Lich]] that replicates himself whenever someone touches his SoulJar.

** [[http://www.scp-wiki.net/scp-50-ae-j SCP-50-AE-J]], a Desert Eagle (the [[AwesomeButImpractical intimidating-looking but not very great]] gun the Agents use in ''Film/TheMatrix'') that shoots violently jingoistic eagles.
** [[http://www.scp-wiki.net/scp-1681 SCP-1681]], an attempt by the USSR to literally bombard their people with symbols of the US that got out of control.

** [[http://www.scp-wiki.net/scp-002 SCP-002]] and [[http://www.scp-wiki.net/scp-004 SCP-004]] provide a concrete example — both articles imply that the Foundation has a policy of [[HeKnowsTooMuch executing all civilian witnesses to anomalous phenomena.]] This was before the introduction of "amnestics" used to erase witnesses' memories.
** In-universe examples happen in some SCP-001 proposals where it's attempted to make the first SCP. Of particular note is [[http://www.scp-wiki.net/dr-gears-s-proposal Dr Gears' Proposal]], where the SCP Foundation initially had a document format completely different to the "modern" Foundation, to the point that objects weren't even labelled as "SCP-[number]".
** Early articles sometimes refer to [[LaserGuidedAmnesia amnestics]] as "amnesiacs". A couple of more recent articles reference this, such as [[http://www.scp-wiki.net/scp-002-j SCP-002-J]].

** One of the reasons [[http://www.scp-wiki.net/scp-3260 SCP-3260]] was written was to lampshade the changes in the site's standards over its history.
* EgomaniacHunter: Well, explorer anyway: [[http://www.scp-wiki.net/harrison-t-winchester-iii-journal-excerpts Harrison T. Winchester III]], who led an expedition to [[http://www.scp-wiki.net/scp-2292 SCP-2292's]] hidden city on behalf of Carter and Dark (Marshall apparently had other plans). From his journal:

* EldritchLocation: Lots of those too. Some noteworthy examples include [[http://www.scp-wiki.net/three-portlands-hub Three Portlands]] (a magical and semi-autonomous city-state looked after by the UIU), [[http://www.scp-wiki.net/scp-2922 Corbenic]] (a multiverse-spanning afterlife home to forgotten gods and monsters), Wiki/TheWanderersLibrary (a PortalCrossroadWorld and magical library used as the primary base of [[LibertyOverProsperity the Serpent's Hand]]), [[HellOfAHeaven Adytum]] (the extra-dimensional kingdom of Grand Karcist Ion and "Heaven" of the Sarkic Cults), and [[http://www.scp-wiki.net/scp-2264 Alagadda]] (another PortalCrossroadWorld ruled over by [[http://www.scp-wiki.net/scp-701 the Hanged King]]).

** [[http://www.scp-wiki.net/scp-1699 SCP-1699]] which is a ''sentient active volcano'' with this personality. It's depressed because it feel it doesn't measure up to other natural disasters.
** [[http://www.scp-wiki.net/scp-353 SCP-353]] has been turning into this, thanks to her confinement. [[TeensAreMonsters A fitting punishment.]] The Foundation shrinks also note her manipulation of diseases causes her great harm and pain, and she does it anyway — similar to a self-harming teenager.

** The SCP Foundation and Global Occult Coalition (which are not necessarily enemies but allied organizations with conflicting viewpoints) have been known to occasionally work together to stop a creator of SCP's. As seen in [[http://www.scp-wiki.net/scp-191 SCP-191]]

** [[http://scp-wiki.wikidot.com/scp-3221 SCP-3221]] was originally sealed away by a fifth-century alliance of sects from both the Church of the Broken God and Proto-Sarkicism, and its cage contains inscriptions and technology/spells from both faiths. ORIA then joined the alliance when it got out a second time, and now the Foundation is working off what they've done before.
** In [[http://scp-wiki.wikidot.com/scp-5000 SCP-5000]], neither the Global Occult Coalition nor the Church of the Broken God wanted humanity to be wiped out and occasionally cooperated as the biggest forces opposing the corrupted Foundation. Ultimately, it wasn't enough, with the [=GOC=] being wiped out and the Church crippled.
* EnhanceButton: [[http://www.scp-wiki.net/experiment-log-191 Subverted by SCP-191]] -- when asked to "Zoom and Enhance" a photo of license plates, she outputs a zoomed-in photo, but fills in the wrong plate numbers because she was unable to read them in the original.

** [[http://scp-wiki.wikidot.com/scp-437 SCP-437-A]] is a grove of 64 trees located at the site of Camp Lakewood, a former summer camp that closed 20 years ago. [[spoiler:The campers are still there. They're inside those trees, apparently still alive and still conscious. Duplicates of them left the camp and continued to live as those people, flawlessly impersonating them.]]
** [[http://scp-wiki.wikidot.com/scp-2571 SCP-2571]] is a recurring nightmare in which the affected visits a theme park called Cragglewood Park, walking down a path with many other children they don't know. The only ride is a huge carousel. Some of the children, before getting on the carousel, hug the other children. [[spoiler:The ones who got on the carousel sacrificed themselves to become trees in the park so their siblings could escape. Afterwards, the survivor's family loses all memory of the sacrificed sibling, but their personal possessions don't disappear. One of the survivors believes he has always been an only child, but there is a room in his house that has always been locked, as far as he knows. He gets visibly agitated and upset when forced to talk about it.]]

** [[http://www.scp-wiki.net/scp-1173 SCP-1173]], The Islamic Republic of Eastern Samothrace, which is either an example of EskimosArentReal that convinces you it's an example of {{Qurac}}, or an example of Qurac that convinces you that it's an example of Eskimos Aren't Real.
** ''Something'' caused the entire Foundation to be [[http://www.scp-wiki.net/scp-1422 completely unaware of the Yellowstone National Park until July 9, 2007.]] [[spoiler:It may have something to do with [[WhamEpisode SCP-2000]], a Thaumiel-class object located in the park and to which only a scarce few have access.]]
* ETGaveUsWiFi: [[http://www.scp-wiki.net/scp-1073 SCP-1073]] is responsible for the current state of computing technology, having taught Foundation personnel to replicate their natural efficiency.

* EverythingsBetterWithDinosaurs: [[http://www.scp-wiki.net/scp-1905 SCP-1905]], [[http://www.scp-wiki.net/scp-1265 SCP-1265]] and [[http://www.scp-wiki.net/scp-250 SCP-250]].
* EverythingsBetterWithMonkeys: An odd side-effect of [[http://www.scp-wiki.net/scp-2820 SCP-2820]]:

** Everything [[http://www.scp-wiki.net/system:page-tags/tag/simian#pages here]] (SCP-2820 doesn't appear probably because the chimp isn't real).
* EverythingsBetterWithPenguins: [[http://www.scp-wiki.net/scp-2720 SCP-2720]] is a hotel in Japan whose rooms can open into ideal breeding ground for groups of threatened penguins. In-universe explanation: [[spoiler:A penguin-themed Foundation front achieved sentience]]. Out-universe explanation: [[spoiler:it was inspired by "an off-hand remark" about a penguin hiding in a hotel room in the author's favorite anime's CD drama]].
* EverythingIsAnIpodInTheFuture: In [[http://scp-wiki.wikidot.com/mackenzie-s-proposal Dr. Mackenzie's Proposal of SCP-001]]. Along with the diary, there is a [-iPad-]-like gray device (its dimensions are roughly those of the 12.9-inch [-iPad-] Pro, only twice as thick) made of an unknown metal, much heavier than it looks (8 kg\18 lb), and featureless besides a keyhole (the key comes along) and a display showing both a progress bar and a number. This data is how corrupted the current reality is, and how many times the device (which allows the user to escape to another universe) has been used.
* EvilPhone: [[http://www.scp-wiki.net/scp-145 SCP-145]] and [[http://www.scp-wiki.net/scp-519 SCP-519]].
* EvilVersusEvil: [[http://www.scp-wiki.net/scp-2217 The Church of the Broken God vs. The Flesh that Hates]]. The Flesh is such a threat that the Foundation, the Horizon Initiative (the [[MultinationalTeam multi-denominational team]]), and the Global Occult Coalition decided to work with the Church to eradicate it.
* ExactWords: The Foundation universe, or at least the version described in the [[http://www.scpwiki.com/wrong-proposal Wrong Proposal]], operates on an EquivalentExchange theory which states that for every concept deemed normal, an anomalous analogue exists as well. For example, the concept of math is countered by SCP-033, the missing number, and the concept of chemistry is countered by SCP-2046, an extended periodic table that converts surrounding matter into elements beyond oganesson that are mostly incompatible with reality. When the Foundation explains an anomaly in the new world and finds no known counterpart, they think the theory has failed them at laast... except since the theory describes a natural law, the anomalous counterpart of the theory would be to simply contradict it.

** [[http://www.scp-wiki.net/scp-971 SCP-971]] is a takeout menu for a restaurant that sells fast food items made from the meat of endangered animals. Somehow, the company has a method of non-lethally extracting meat from said endangered animals, not killing them but causing them to lose weight and muscle mass.
** One of the objects from the [[http://www.scpwiki.com/log-of-anomalous-items log of anomalous items]] is a softboiled egg from an unidentifiable species approximately 0.7 meters (2.3 feet) in height, retrieved from an illegally-operated restaurant in South America that served various exotic dishes, including snow leopard, chimpanzee, wooly mammoth, [[ImAHumanitarian human,]] and SCP-███.

** The data extracted from [[http://www.scp-wiki.net/scp-328 SCP-328]]. To avoid DontExplainTheJoke, spoilered: [[spoiler:the data describes an ordinary human laptop computer, as described by members of a decidedly alien species who might exist in a different universe with slightly different physical laws. The aliens describing the laptop seem to belong to their civilization's equivalent of the SCP Foundation. To complete the joke, SCP-328 seems to be the alien's version of a laptop computer, and if the Foundation's description of it was to make its way back to the aliens they'd consider it to be an ExpospeakGag description of their laptop]]. [[spoiler:And they seem to be truly StarfishAliens, as the mere act of a laptop emitting light manages to kill 4 researchers.]]
** [[http://www.scp-wiki.net/scp-1960-j SCP-1960-J]] is a free-floating sphere made of white stone which moves in a continuous circular path, despite lacking any visible means of support or propulsion. It appears to absorb or suppress sound, changes color as one gets closer to it, has extreme temperature variations despite having no internal heat source, one needs to wear an environmental suit to touch it without dying, and it draws objects towards it. Fortunately, it is located a safe distance from anyone that it could harm, but a change in its circular motion could cause an XK-class end-of-the-world scenario. [[spoiler:It is Earth's moon.]]
** One of the last entries in the [[http://www.scp-wiki.net/experiment-log-t-98816-oc108-682 attempts to kill SCP-682]] is the beast [[spoiler:beating on a dead horse]].
** Both PlayedForDrama and Justified with [[http://www.scp-wiki.net/scp-4100 SCP-4100]]. Many of the Triumvirate's pictograms use this trope to describe everyday earthly concepts related to containing [=SCPs=], being aware that future discoverers may be StarfishAliens. For example, a diagram of potassium cyanide (represented by a series of tallies indicating the component elements) is used as shorthand to mean "deadly (to carbon-based life)".

* ExtranormalPrison: The Foundation's main purpose is creating these. And the containment methods add another layer for some [=SCPs=]. They also weren't the first, as [[http://www.scp-wiki.net/scp-1000 the Children of Night]] had previously created [[http://www.scp-wiki.net/scp-2932 "Titania's Prison"]] to serve in this purpose for them while they ruled the Earth.

** A D-class who was known amongst the other Ds as "[[ExtremeOmniGoat Goat]]" for being able to stomach the horrible food the Foundation gave them also became a true Extreme Omnivore capable of digesting rock, metal, etc. after drinking a mixture of water and [[http://www.scp-wiki.net/scp-1049-j SCP-1049-J]].
** [[http://www.scp-wiki.net/scp-913 Mr. Hungry]] is a humanoid SCP with an extremely fast metabolism that requires an intake of 2000 calories every two hours. If the condition is not met, he will enter a trance state and eat anything solid on sight, whether it is living or not, for a period of time.
** [[http://www.scp-wiki.net/scp-524 SCP-524]] is a rabbit that will eat ''anything'', including [[{{Autocannibalism}} itself]] — by [[BodyHorror turning its mouth inside out]] until there's nothing left of it. Thirty minutes later, ''[[MindScrew it will appear in the spot it ate itself in completely unharmed]]''.
* TheExtremistWasRight: The Shark Punching Center were right to fear sharks. In [[http://http://www.scp-wiki.net/captain-kirby-s-holistic-proposal Captain Kirby's proposal]], sharks invent a [[MakesJustAsMuchSenseInContext a vaccine for being punched]] and take over San Francisco. Luckily, [[spoiler:[[ExactWords the vaccine doesn't protect them from kicks]]]].

* FaceHeelTurn: The Foundation as a whole undergoes one of these after discovering [[ThingsManWasNotMeantToKnow something horrible]] in [[http://www.scp-wiki.net/scp-5000 SCP-5000]].

** Mentioned in [[http://scp-wiki.wikidot.com/scp-001-o5 Dr. Bright's SCP-001 Proposal]]. They're the ruthlessly violent kind; more like orcs, but with a weakness to [[ColdIron iron]]. O5-1 wiped them out after being forced to make a DealWithTheDevil in the form of [[GreaterScopeVillain The Factory]]. This wasn't the first time they appeared, either, with [[http://www.scp-wiki.net/scp-1323 SCP-1323]] being [[IncrediblyLamePun their fairground]]. It's also implied that they once held dominion over the Earth before being overthrown by SCP-1000 (as implied by SCP-2932).
** Another example exists in the inhabitants of '''[[http://www.scp-wiki.net/taboo the anomalous location that cannot be referred to as SCP-4000]]'''. Their forms vary, but they are universally whimsical, contradictory, bound to etiquette and oaths, and [[spoiler:prone to violently cursing anyone who tries to force - intentionally or otherwise - a concrete identity onto them. Giving oneself an identity is also ill-advised, as disobeying the rules of '''the land where language is dangerous''' afterwards renders you vulnerable to [[GrandTheftMe literal identity theft]]. They also all resemble {{Humanoid Abomination}}s (such as one fellow with the head of a rabbit) because the Foundation "stole all of their names." They're actually the same fairies from Dr. Bright's SCP-001 Proposal, being the surviving refugees of the Foundation's genocide... and they ''really'' want to get the Foundation back for that. Some other [=SCPs=], such as [[http://www.scp-wiki.net/scp-1826 SCP-1826]], are suggested to be related to them in one manner or another]].
** [[http://www.scp-wiki.net/three-portlands-hub Three Portlands]] has a large refugee population made up of entities calling themselves "the Sidhe," who largely evacuated to the city in question after their home realm of Avalon started to collapse in on itself in 1905 due to backlash from the Sixth Occult War. [[http://www.scp-wiki.net/scp-2952 SCP-2952]] is their subway, and it is all but stated that the Sidhe are connected in some way to the faeries described in Dr. Bright's 001 Proposal above.
%%** [[http://www.scp-wiki.net/scp-562 They also like to party.]]
%%** [[http://www.scp-wiki.net/scp-2615-j And they're magic.]] [[spoiler:[[http://www.scp-wiki.net/scp-2615 If you believe in them.]]]]
* FakeRealTurn: [[http://scp-wiki.wikidot.com/scp-4006 SCP-4006]] resulted in the world believing that Massachusetts was an inhabited area when in fact it was not. The Foundation takes advantage of this and sets up a bunch of facilities in the area, then disguises them to look like the regular buildings and infrastructure everyone thought was in Massachusetts. Eventually it gets to the point where the entirety of Massachusetts has been built and is inhabited mainly by civilians.
* FantasticFlora: Several [=SCPs=] are examples of this, such as [[http://www.scp-wiki.net/scp-937 SCP-937]], [[http://www.scp-wiki.net/scp-1277 SCP-1277]], and [[http://www.scp-wiki.net/scp-1478 SCP-1478]].

%%** In [[http://www.scp-wiki.net/scp-953 SCP-953]] is a ''kumiho''.
%%** [[http://www.scp-wiki.net/scp-1845 SCP-1845]]'s leader, King Eugenio II.

** Parodied with [[http://www.scp-wiki.net/scp-1171 SCP-1171]], who is some sort of otherworldly creature located apparently in an alternate universe and is quite (passively) racist against humans. Apparently "gamete" is a racial slur against humans where he comes from. At least he's pretty nice to them up front.

* FateWorseThanDeath: A common outcome of many [=SCPs=]. Especially when they combine an irreversible [[http://www.scp-wiki.net/system:page-tags/tag/transfiguration transfiguration effect]] with AndIMustScream.

* FeatheredFiend: [[http://www.scp-wiki.net/scp-1387 SCP-1387]], a giant seagull that [[spoiler: compels people to go into its airplane-cabin interior and apparently turns them into birds]].

* FeelNoPain: While conducting purges of uncorrupted Foundation soldiers in [[http://www.scp-wiki.net/scp-5000 SCP-5000]], the Foundation would test them by stabbing them. Most had no reaction, while those who did were promptly killed. One Foundation scientist claims that humanity as a whole is not supposed to feel pain.

** [[http://www.scp-wiki.net/scp-649-2568-j SCP-649-2568-j]], a snake that reshapes geological features that it finds too flat, explaining itself with [[spoiler:"I like big buttes and I cannot lie". Add that the species is listed\pictured as an anaconda and the number spells [[Music/SirMixALot MIX-ALOT]]...]]
** [[http://scp-wiki.wikidot.com/scp-0002-j SCP-0002-j]] is a talking toilet that wants to write a book about his life because [[spoiler:he's seen some shit]].
** [[http://www.scp-wiki.net/holy-crap-this-is-a-long-christmas-tale The 12 Days of Site 87's Christmas]] takes place over the course of twelve days before Christmas 2014, and involves the Krampus, a magical Christmas tree that makes its own ornamentation, and a fight between the two of them. [[spoiler:In the final fight between the Tree and the Krampus, one Dr. Partridge gets knocked on his ass by a blast from the former, and transformed into, as one of the characters puts it, "A small tree of the genus ''Pyrus''." In other words, Dr. Partridge is a Pear Tree.]]
** Again, in [[http://www.scp-wiki.net/happy-howlidays Happy Howlidays]], which involves a werewolf Santa of all things. [[spoiler: Said Werewolf Santa followed throughout the story by a character named Virginia, and eventually ends up concussing a Foundation researcher and a claw shot off by a sniper before dying. After the fact, the delirious, concussed researcher finds the claw and proclaims, "Yes, Virginia, There's Santa Claws."]]
** [[http://www.scp-wiki.net/scp-3304 SCP-3304]] is a portal to a fiery hell dimension being used for geothermal energy. Only, the Devil himself lives there and the use of the realm as a geothermal power source is both draining it and affecting worldwide probability. [[spoiler:Hell is freezing over.]]
* FemaleMisogynist: [[http://www.scp-wiki.net/scp-847 SCP-847]], a female mannequin that attacks any women in its vicinity.

** [[http://www.scp-wiki.net/scp-2039 SCP-2039]], the Pikes and the Wagners, a pair of families who are doomed to attack each other forever with anomalous weapons (examples: UsefulNotes/WW1-era mines, Super Soakers, and wool gloves that [REDACTED]) because a mysterious gray-eyed man [[ItAmusedMe likes a good story]].
** [[http://www.scp-wiki.net/scp-2158 SCP-2158]], an anomalous handgun whose owner and target are related to the real-life [[https://en.wikipedia.org/wiki/Pleasant_Valley_War Pleasant Valley War]], a feud so deadly it delayed Arizona's statehood by a decade because it showed the territory wasn't civilized enough to join the US.

** [[http://www.scp-wiki.net/scp-151 SCP-151 ("The Painting")]]. SCP-151 is a painting of an underwater scene. Anyone who looks at it will slowly drown over the next 24 hours.
** [[http://www.scp-wiki.net/scp-800 SCP-800 ("An Eastern History")]]. SCP-800 is an East Asian paper scroll painting that alters its appearance to symbolically represent current armed conflicts in Asia.
** [[http://www.scp-wiki.net/scp-1074 SCP-1074 ("Stendhal's Nightmare")]]. SCP-1074 is a painting called ''Stendhal's Nightmare'' that consists entirely of a grey background. Anyone looking at it suffers from Stendhal syndrome (increased heart rate, sweating, and vertigo). They will describe seeing a highly detailed painting, but each person will give a different description.
** [[http://www.scp-wiki.net/scp-1753 SCP-1753 ("Vertigo")]]. SCP-1753 is a painting of El Capitan in Yosemite National Park. It causes the viewer to perceive a drop of any height as being a 2,000-foot high cliff face. If the viewer jumps over the drop, they will impact the ground as if they had actually fallen 2,000 feet.
** [[http://www.scp-wiki.net/scp-1891 SCP-1891 ("Constructeur")]]. SCP-1891 is a painting of a humanoid clothed in construction tools (wrenches, hammers, etc.). If any other painting is brought into the same structure as SCP-1891, the other painting will change to a depiction of large industrial machines. The humanoid will disappear from SCP-1891 and appear in the other painting, maintaining the machines.
** [[http://www.scp-wiki.net/scp-2071 SCP-2071 ("Sir Michael Cavendish, in the Guise of the King of Serpents")]]. SCP-2071 is a painting of a snake man wearing an 18th-century British military uniform. Anyone touching the painting dies from snake venom created by their own body. All reptiles within 5 kilometers of the painting try to move toward it if possible. There are three other anomalous paintings by the same painter: ''The Rood and the Pit'', ''The Hunting Party'', and ''Celia Penrose, in the Guise of a Fountain''.

** Combined with GrandTheftMe (literally): [[http://www.scp-wiki.net/scp-2885 SCP-2885]] is a pane of glass which allows people to find alternate universe versions of themselves and take over their minds and lives. [[spoiler:Very rarely, an alternate crosses over into ''this'' world.]]

* {{Flanderization}}: Dr. Bright (the character, not the author) has been subjected to this, to a degree. He started out as an eccentric researcher who just happened to live inside an SCP, but thanks largely to [[http://www.scp-wiki.net/the-things-dr-bright-is-not-allowed-to-do-at-the-foundation this list]], he's seen as [[DeathSeeker a psychopathic pervert with a death wish]], with some justification in the fact that the SCP he's stored in apparently absorbs part of the soul of the person whose body he's residing in. At one point, it was stated that [[CreatorBacklash Dr. Bright the author actually hated the list because of what it did to his character.]] Some tales that Dr. Bright the character is featured in manage to avert this, but the list continues to loom over the character.
* FlashInThePanFad: [[http://www.scp-wiki.net/scp-1425 SCP-1425]] is ''Star Signals'', a self-help book published by the Fifthist Church with mind- and reality-altering effects. Within two weeks of publication, it was a national best-seller with several celebrity endorsements. Within another two weeks, ''Star Signals'' was completely forgotten — because the Foundation realized it posed a threat of a [[RealityWarper CK-class reality restructuring event]], acted to seize all copies of the book, and used Protocol Ophiuchus and Project LETHE to erase all public records and memories of it.
* FlatWhat: Agent Howard's reaction when [[http://www.scp-wiki.net/scp-4950 SCP-4950]] quotes ''Fortnite'' as it's being exorcised.
* FlatWorld: [[http://www.scp-wiki.net/scp-1372 SCP-1372]] appears to be the edge of the earth. The problem isn't ships and people going over the edge, it's when [[CameBackWrong they come back]] and try to get others to follow:

* FlechetteStorm: [[http://www.scp-wiki.net/scp-143 SCP-143]], a grove of [[CherryBlossoms Japanese cherry trees]] with impossibly sharp petals. May or may not be a shout-out to ''Manga/{{Bleach}}''[='s=] Senbonzakura.

* FlingALightIntoTheFuture: Inverted with [[http://www.scp-wiki.net/scp-304 SCP-304]], amongst others. 304 appears to be a listing of the names of all world leaders, including American Presidents, Chinese Presidents, and... ''O5s''. Specifically, they list 63 American presidents, a redacted number of O5s, and 7 names in an encoding style that hasn't been invented yet... then abruptly ''stops.'' What happens in roughly 100 years to abruptly stop the list of human leadership is unknown.
* FlippingTheBird: What [[http://www.scp-wiki.net/scp-1884 SCP-1884]]-[[MultiArmedAndDangerous B]] does with her many arms to describe how she felt during her captivity in the Circus of The Disquieting:

* FlowerMotifs: During [[http://www.scp-wiki.net/lily-s-proposal an SCP-001 event]], flowers bloom across the planet. In addition, the skies clear up and all pollution disappears from the atmosphere.
* FlowerMouth: [[http://scp-wiki.net/scp-929 SCP-929 ("The Cuckoo")]]. When SCP-929 engages in combat, its head splits open like a flower, releasing its CombatTentacles.

** Hard to Destroy Reptile/682, the indestructible sapient "reptile" that can survive being tossed into the sun vs. [[http://www.scp-wiki.net/scp-1364 1364, the excessively vulnerable non-sapient anteater]] that's burned by its own tears.
** The Hard to Destroy Reptile, the horrifically-powerful sharp lizard that wants to actively kill everyone in its line of sight, vs. [[http://www.scp-wiki.net/scp-999 999, a soft, super-friendly blob of jelly who has tickling as the greatest harm it can do, subsists on candy, and doesn't wish harm on anything, even the aforementioned lizard]].

[[http://www.scp-wiki.net/scp-1048 SCP-1048]] and [[http://www.scp-wiki.net/scp-2295 SCP-2295]] both look and act cute, but 1048 is actually evil and makes copies of itself (often out of human flesh) that kill people, while 2295 is benign and heals people in need (albeit in a fashion that qualifies as BodyHorror, but ''not'' HarmfulHealing). 1048 and [[http://www.scp-wiki.net/scp-1055 SCP-1055]] are both evil, but 1048 creates copies of itself out of the flesh of others while 1055 grows its own flesh infinitely.[[note]]Additionally, 1048 used to be treated nicely because of its outwardly good behaviour, which allowed it to wreak havoc; 1055 reacts to hostility, so it's contained by someone treating it nicely.[[/note]] 1055 harms people with its constantly-growing flesh while 2295 heals people by using its own fabric and stuffing to make replacement organs for them (if no other materials are available). Finally, [[http://www.scp-wiki.net/scp-1145 SCP-1145]] is friendly like 2295 and just wants to comfort people; unfortunately, its radioactivity causes it to be dangerous like 1048 and 1055.

When the Foundation succeeded in observing the phenomenon [[spoiler:it disappeared, possibly with the rest of the SCP-verse, because (according to the comments) the researchers didn't realize the entries were also narratives. Oh, and the thing moves upwards through layers of narrative, and the SCP-verse is a fictional narrative in ''our'' world...]]

[[spoiler:It is the same line [[http://scp-wiki.wikidot.com/scp-682 SCP-682]] expresses when talking about humanity, indicating that the EldritchAbomination they found buried in humanity's collective unconscious is the nightmarish horror responsible for [=SCP-682's=] OmnicidalManiac attitude towards mankind.]]

** The fact that S. Andrew Swann is listed as one of the agents who helped right [[http://www.scp-wiki.net/scp-5999 SCP-5999]] serves as a pretty subtle indicator for this [=SCP=] [[spoiler:actually being [[RageAgainstTheAuthors Procedure ZK-001-Alpha]] finally put into action]].

* GentleGiant: [[http://www.scp-wiki.net/scp-516 SCP-516]], the Intelligent Tank.
* GenreBlindness: Many [=SCPs=] are very, very obviously objects or people out of mythology and legend. The writeups (despite supposedly being by professionals for whom documenting every possibly-relevant detail is often a matter of life or death or worse) will never, ever notice or comment on this. [[ContractualGenreBlindness This is sometimes explained as an attempt to disallow cultural expectations from coloring observations.]] Case in point, [[http://www.scp-wiki.net/scp-2600-ex SCP-2600]], a completely mundane phenomenon which was only presumed anomalous due to preconceived notions (i.e., [[WrongGenreSavvy supposed genre savvy]]). See also the fact there are two, possibly three, entirely separate and distinct entities that are each implied in mutual contradiction to secretly be the one "true" god of the Abrahamic faith. Fairies, dragons, genies, zombies, and the horsemen of the apocalypse have had similar treatment.

* GeometricMagic: [[http://www.scp-wiki.net/scp-259 SCP-259]] acts as this, and no good comes of it.
* GhostlyAnimals: The entry "[[http://scp-wiki.wikidot.com/scp-1111 The White Dog]]" is this. The ghost of a white dog constantly protects the ghost of his master, who was hanged from a tree and constantly suffers the pain of the hanging. The closer the dog is to his master, the more the master appears to suffer, but the proximity of living humans alleviates that suffering.
* GhostlyGoals: [[http://www.scp-wiki.net/scp-2111 SCP-2111]] deals with a thing that makes deceased Foundation agents return, and create new memetic agents\hazards.
* GiantFlyer: [[http://www.scp-wiki.net/scp-1387 SCP-1387]], a 20-meter long seagull that has an airplane cabin inside it.
** [[http://www.scp-wiki.net/scp-1608 SCP-1608]] is a blue whale that not only flies, but is [[{{Intangibility}} intangible]].
* GhostMemory: [[http://www.scp-wiki.net/scp-5161 SCP-5161]], a former D-class test subject. Back in the 50s, the Foundation tested the first amnestic prototype on her, and and she now possesses ''every single memory'' the Foundation has wiped from the global population over the past 70 years or so. What's more, it's heavily implied that when she dies, all those memories will return to their original owners.

** [[http://www.scp-wiki.net/scp-2922 SCP-2922 ("Notes From the Under")]]. SCP-PC-005, "The Impenetrable" is a RealityWarper that lives in the afterlife known as Corbenic. It resembles a gigantic spider.
* GlitchEntity: [[http://www.scp-wiki.net/scp-951 SCP-951]], AKA LUCAS. There also entities who exist only to screw with computer interfaces and\or reality, such as [[http://www.scp-wiki.net/scp-732 SCP-732]].
* AGlitchInTheMatrix: In [[http://scp-wiki.wikidot.com/mackenzie-s-proposal Dr. Mackenzie's Proposal of SCP-001]]. The civilization from which the Administrator originates learned to manipulate the very fabric of reality... which also opened cracks in it, the Corruption.
* {{God}}: [[http://www.scp-wiki.net/scp-343 SCP-343.]] At least he claims to be, anyway; he could just be an extremely powerful RealityWarper.
** Also, the Abrahamic faiths seem to be right. A number of [=SCPs=] require containment procedures to be performed by individuals with good standing in one of the three monotheistic religions. There is no mention of similar circumstances for Hindus or any other religion. Then there is the entry for [[http://www.scp-wiki.net/dr-clef-s-proposal Dr. Clef's proposal for SCP-001]]. Of course, it could just be that most, if not all, of the writers for the site are from the three religions and don't want to make a ThemeParkVersion of any of the other religions.

** The GOC claims to have [[http://goc.wikidot.com/lte-0913-exmachina killed God]], causing several people to feel it and leading to [[HistoricalInJoke Nietzsche's God is Dead spiel.]] Irony points for using mages.
** The [[spoiler:figure behind the veil]] in [[http://www.scp-wiki.net/scp-1348 SCP-1348]] is strongly implied to be God. He hurts because [[spoiler:he created humanity by mistake]].
* AGodAmI: [[http://www.scp-wiki.net/scp-1832 SCP-1832]]: "[And I knew it.] That I had the power. [[HealingHands To heal]] or to not, to judge the wicked, to deny a man love and mercy when he needs it most. What I knew then was what it's like to be God." [[spoiler:And when he gets that powerful feeling, he can heal more effectively... for a while. Afterwards, he has to be a {{Jerkass}} to regain that feeling.]]
** [[http://www.scp-wiki.net/scp-2820 SCP-2820]] is a KillSat that believes it's [[Myth/HinduMythology Kalki, the final avatar of Lord Vishnu]]. Given [[AllMythsAreTrue the nature of the Foundation-verse]] and the sophistication of the AI's ButterflyOfDoom assassinations, it's not clear even to the researchers if it's just a berserk AI or if it really is Kalki incarnated into a Kill Sat.
* GodIsEvil: Depending on which account is true, the God of the world accessible through [[http://www.scp-wiki.net/scp-093 SCP-093]] [[spoiler:is either a {{Jerkass}} who started a wholly unnecessary war for the hell of it, the methods of which caused TheEndOfTheWorldAsWeKnowIt as it created grotesque undead monsters... or is an EldritchAbomination who invaded that world and used the pretense of being God to enslave humanity, the method used and technology it granted in the process creating the aforementioned grotesque undead monsters.]]

** [[http://www.scp-wiki.net/scp-1030 SCP-1030]] is pretty clearly either a reference to, or even ''[[AllMythsAreTrue the original]]'' Golem from Jewish folklore.
** Nicknamed "Periodic Golems", [[http://www.scp-wiki.net/scp-2300 SCP-2300-1 through -98]] are tiny, blocky, shape-shifing humanoids made from the elements, hydrogen to californium.

** [[http://www.scp-wiki.net/scp-3001 SCP-3001]] sees Dr. Robert Scranton slowly lose his mind as he's stuck in a VoidBetweenTheWorlds with nothing but [[CompanionCube a device with a blinking red light]] for company. The BodyHorror that comes along with it doesn't do his mental state any favors.

** [[http://www.scp-wiki.net/scp-752 SCP-752]] was created by a group of philosophers with the intention of being a perfect society. And it worked! The inhabitants of the city are motivated solely by the "greater good" of their community! Only, that means they have no emotions, no empathy, no desires, pretty much nothing even remotely human. They're more akin to a colony of ants than a human society. Oh, and of course, they're vastly more technologically advanced than the outside world. According to the Foundation, if they ever leave their cavern, they'll wipe out humanity and become the dominant species.
** That are many SCP's, such as [[http://www.scp-wiki.net/scp-1975 1975]], that appear in backstory to have been originally created as tools of revenge against a single person or for a single slight, only for it's anomalous effects to not end after vengeance is served - becoming horrific blights that far outstrip their creators' intentions.
** In [[http://www.scpwiki.com/scp-2718 SCP-2718]], the [=O5s=] use an experimental resurrection procedure to bring back O5-11, with the hope that he'll return to life just long enough to give out the secret keyword needed to replace him, then die once again. The procedure ends up giving him a full recovery, which at first seems wonderful...until -11 reveals what the afterlife is, something that the Foundation had not been able to learn about of due to the way previous revival techniques had worked (either cloning or space-time distortion), and said afterlife is far, ''far'' worse than any living human could possibly imagine. This leads to a riot amongst the [=O5s=], O5-1 ordering the use of amnestics amongst themselves, O5-11 being marked for a second termination, and O5-7 planting an unremovable, unmodifiable record of the whole ordeal in the Foundation's digital systems, forcing the Foundation to implement special procedures to minimize the chances of someone accessing the record which comes at the cost of forcing personnel assigned to the task to either take an amnestic that is implied to be extremely powerful or face termination. In short, had the revival method simply given O5-11 only enough time back in the living realm to give out his secret word, none of this would've happened.

** [[http://www.scp-wiki.net/scp-1755 SCP-1755]], a Keter-class SCP that threatens the very existence of the global cotton crop, resulted when two college guys tried to create a device that [[WardrobeMalfunction made women's clothes fall off]].

** [[http://www.scp-wiki.net/clavis Clavis]], meaning "key". Based on [[http://www.scp-wiki.net/dr-clef-s-proposal Dr Clef's Proposal]]. "'''clef''''" is French for "key".
** [[http://www.scp-wiki.net/corvus Corvus]], meaning "crow". Based on [[http://www.scp-wiki.net/mackenzie-s-proposal Dr. Mackenzie's Proposal]]. The author’s full username when posting the article was "'''Raven''' Mackenzie".
** [[http://www.scp-wiki.net/cygnus Cygnus]], meaning "swan". Based on [[http://www.scp-wiki.net/sandrewswann-s-proposal the proposal]] by S Andrew '''Swan'''n.
** [[http://www.scp-wiki.net/lux Lux]], meaning "light". Based on [[http://www.scp-wiki.net/scp-001-o5 the proposal by]] Dr. '''Bright''' (who is now known as [=TheDuckman=]).
** [[http://www.scp-wiki.net/pila Pila]], with multiple meanings, one of which is "ball". Based on [[http://www.scp-wiki.net/jonathan-ball-s-proposal the proposal by]] Jonathan '''Ball'''.
** [[http://www.scp-wiki.net/rota Rota]], meaning "wheel". Based on [[http://www.scp-wiki.net/dr-gears-s-proposal Dr Gears' Proposal]]. The English word "rotate" originates from "rota", and '''gears''' rotate.
** [[http://www.scp-wiki.net/virr Virr]], intentional misspelling of "vir", meaning “man”. Based on [[http://www.scp-wiki.net/dr-manns-proposal the proposal]] by Dr. '''Man'''n.
** [[http://scp-wiki.wikidot.com/numerus Numerus]], based on [[http://scp-wiki.wikidot.com/qntm-s-proposal the proposal]] by '''qntm''' - both "numerus" and "quantum" mean 'quantity'.
** [[http://www.scp-wiki.net/visium Visium]], derived from "visius", meaning “looking”. Based on [[http://www.scp-wiki.net/scantron-s-proposal the proposal by]] '''Scan'''tron.
** [[http://scp-wiki.wikidot.com/acies Acies]], meaning "sharp edge". Based on [[http://scp-wiki.wikidot.com/spikebrennan-s-proposal the proposal by]] '''Spike''' Brennan.
** [[http://scp-wiki.wikidot.com/capitis Capitis]], meaning "head". Based on [[http://www.scpwiki.com/captain-kirby-s-proposal the proposal by]] '''Captain''' Kirby.
** [[http://scp-wiki.wikidot.com/flos Flos]], meaning "flower". Based on [[http://www.scpwiki.com/lily-s-proposal the proposal by]] '''Lily'''.
** The only one more vague is [[http://scp-wiki.wikidot.com/illac Illac]], meaning "there", based on [[http://www.scpwiki.com/billiths-proposal the proposal by]] Billith, with the author saying the word was chosen as a rough Latin translation of his alter ego, Harkness.
** Two of them have titles based on the content, [[http://www.scpwiki.com/umbra Umbra]], meaning "Shadow" (inspired by "[[http://scp-wiki.wikidot.com/shaggydredlocks-proposal When the Day Breaks]]) and [[http://www.scpwiki.com/serus Serus]], meaning "late" ([[http://www.scpwiki.com/djoric-dmatix-proposal The 36]]).
* GratuitousNinja: [[http://www.scp-wiki.net/scp-2928 SCP-2928]]. [[YourMindMakesItReal They're stealthy and invisible because everyone believes they're stealthy and invisible]], at least until the creation of [[Manga/{{Naruto}} certain media]] which spread the HighlyVisibleNinja trope.

* GreyGoo: The ApocalypseCult "The People of the Lie" ''worship'' a god of nanotechnology ("the Archon Lord, a.k.a. [[http://www.scp-wiki.net/scp-4950 SCP-4950]]) that would inflict this upon our universe if it was ever successfully summoned.
* GrimyWater: [[http://www.scp-wiki.net/scp-242 SCP-242]] and [[http://www.scp-wiki.net/scp-676 SCP-676]] have an effect like this, disintegrating anyone and anything that enters them. Inverted in that they're both supernaturally clean as a result of their effects.
* GrowsOnTrees: [[http://www.scp-wiki.net/scp-392 SCP-392]], is one such example. It's a tree augmented by the Daevites, which grows human heads instead of fruit.
* GroinAttack: [[http://www.scp-wiki.net/scp-113 "In about half of failed transformation, partial or complete obliteration of the genitals is experienced..."]]
** Additionally, [[http://www.scp-wiki.net/scp-5972-j SCP-5972-J]] does this as its primary function.
** Also implied about [[http://scp-wiki.wikidot.com/scp-203 SCP-203's]] UnwillingRoboticisation; out of all the body parts that were mechanized, one was completely removed and it's censored with an [EXPUNGED] block...
** One result from putting a stress ball into [[http://www.scp-wiki.net/scp-914 SCP-914]] while it was set to fine was a stress ball that would throw itself at the nearest person's face every 1-5 minutes. If the face was somehow protected, it would aim for either their stomach or their crotch.
** [[http://www.scp-wiki.net/scp-50-ae-j "D-1409 is to be incinerated entirely, after his testicles are recovered from SCP-50-AE-1."]]
* GroundhogDayLoop: [[http://www.scp-wiki.net/scp-1733 SCP-1733]], a recording of a season-opening basketball game between the NBA's Boston Celtics and Miami Heat. Each time someone watches the tape, the game is played again, from the beginning, with differing results. Slowly, everyone involved (the players, coaches, announcers and fans) realize that they're reliving the same game over and over again, and... things get ugly.
** Examples where the people don't (usually) notice things repeating can be found in the [[http://www.scp-wiki.net/system:page-tags/tag/loop#pages "loop" tag]]. Some have indicative names ("Observable Time Loop", "33 Second Man", "Time-Locked Town", "Infectious Time Loop", "Looping Kaiju Killing").

It's [[http://www.scp-wiki.net/scp-931 SCP-931.]]\\

** [[http://www.scp-wiki.net/scp-524 SCP-524]], the ExtremeOmnivore rabbit.
** [[http://www.scp-wiki.net/scp-979 SCP-979]], a sculpture of a hare that causes synesthesia.

*** [[http://www.scp-wiki.net/scp-1284 SCP-1284]], young girls whose limbs detach and become carnivorous rabbits if exposed to moonlight [[spoiler:(which is apparently the doing of their "king", who "consummates" their marriage by killing them when they have their periods)]].
*** [[http://www.scp-wiki.net/scp-1282 SCP-1282]], rabbits who turn into human hunters who hunt rabbits during the full moon.
*** [[http://www.scp-wiki.net/scp-1818 SCP-1818]], a manifestation of a living-dead rabbit on a certain company's airplanes (no moonlight necessary) [[spoiler:and whatever's doing it is forgetting how its "thing" is supposed to go]].
** [[http://www.scp-wiki.net/scp-1793 SCP-1793]], an old rabbit who can make things appear.

** The amulet with healing properties ([[http://scp-wiki.wikidot.com/scp-427 SCP-427]]) that, if used improperly, will continue to "heal" the target even after bringing them up to perfect health. They eventually mutate into a nigh-invincible mass of flesh with beyond human intelligence and a desire to make other people become like them.
** There's also a fixing robot ([[http://scp-wiki.wikidot.com/scp-212 SCP-212]]) that likes to rejuvenate your organs and makes other alterations based on its own unknown criteria. It's about as likely to make you able to breathe under water as just killing you. Employees are allowed to volunteer for treatment by it, obviously at their own risk.
** There's also [[http://www.scp-wiki.net/scp-135 SCP-135]], a girl with an aura that makes her and any other organic matter within a 10 cm radius immortal while causing rapid and uncontrolled cell growth — AKA ''cancer'' — within 2.25 m. Having developed this aura in utero, she is stuck in a fetal position and permanently encrusted in a constantly growing mass of plant, fungus, and microorganisms. The most that can be done for her is to have robots cut off some of the excess matter when it gets too big. The worst part? ''[[AndIMustScream She has full brain activity.]]''
** To some extent, [[http://www.scp-wiki.net/scp-049 SCP-049]] could be thought of as this. An entity resembling a bird-masked doctor from the time of the Black Plague, SCP-049 can apparently sense some form of "disease" in randomly determined human subjects. His "patients" are forced to undergo a fatal surgery once he's picked them out. Trouble is, they consistently reanimate after surgery, attempting to violently [DATA EXPUNGED] any un-surgerified humans they find.

** [[http://www.scp-wiki.net/scp-1370 SCP-1370]], no matter what he promises to do to you.
** [[http://www.scp-wiki.net/scp-705 SCP-705]]. There's only so much five ounces of Play-Doh can hope to accomplish, no matter ''how'' accurately it can replicate a functioning army.

---> '''Foundation terminal:''' ''(during access attempt to [[http://www.scpwiki.com/scp-2317 SCP-2317]] Level 4 file)'' YOU ARE ATTEMPTING TO ACCESS A '''SECURITY LEVEL 4 (TOP SECRET) FILE'''. PLEASE NOTE THAT ACCESS TO THIS FILE IS RESTRICTED TO PERSONNEL WITH LEVEL FOUR SECURITY CLEARANCE DIRECTLY IN CONTACT WITH SCP-2317.

** Any non-O5 personnel who is "contaminated" with water from [[http://www.scpwiki.com/scp-006 SCP-006]] are to be confined, experimented on, and terminated; the last step in particular is to ensure that they and everyone else who isn't an O5 don't learn that SCP-006 is actually a FountainOfYouth.

* HealingHands: [[http://www.scp-wiki.net/scp-1832 SCP-1832]]; too bad he [[spoiler:can only power up by getting that feeling you get when you play god]].
* TheHecateSisters: [[http://www.scp-wiki.net/scp-1765 SCP-1765]], a trio of female (or feminine) entities who took over a Foundation Site to run experiments on the people trapped within. According to the author, they're a mix of [[Myth/ClassicalMythology the Three Fates]], [[Theatre/MacBeth the three witches]], and [[Literature/{{Discworld}} the Maid, the Mother, and... the Other One]], with [[Manga/AhMyGoddess the three Norns]] thrown in. A sample of their personalities:

* {{Hellgate}}: [[http://www.scp-wiki.net/scp-616 SCP-616]] and [[http://www.scp-wiki.net/scp-1844 SCP-1844]].
* HellIsThatNoise: Many [=SCPs=] feature snippets of sounds. Most of them sound absolutely horrifying. [[http://scp-wiki.wikidot.com/scp-270 SCP-270]], [[http://scp-wiki.wikidot.com/scp-216 SCP-216]], and [[http://scp-wiki.wikidot.com/document-860-iii-and-iv an SCP-860 expedition]] are just a few examples.

* HeroicSuicide: [[spoiler:Upon realizing that he himself is the only constant that makes sure his own BadFuture happens by traveling back in time, [[http://scp-wiki.wikidot.com/scp-4989 Simon Kells]] kills himself, giving the Foundation a chance of averting the hellish future dominated by the Scarlet King]].

** [[http://www.scp-wiki.net/scp-1958 SCP-1958]], a VW microbus currently en route for Alpha Centauri. Investigation revealed that a borderline MadScientist developed radical propulsion technology that allowed four hippies to blast off to the stars in the fifties. However, the idea of hippies in space quickly stops being funny when you read the diary: it turns out none of them knew of the distances involved (they only make it past the moon after a few days, thinking they'd reach Alpha Centauri in a few weeks, and the bus is currently around Mars) and die of scurvy or starvation.
** [[http://www.scp-wiki.net/scp-907 SCP-907 ("An Exploratory Vehicle")]]. SCP-907 is a 1960's Volkswagon van painted in a hippie motif (flowers, butterflies, etc.). It is capable of {{Teleportation}} to planets in other solar systems.
** [[http://www.scp-wiki.net/scp-1574 SCP-1574 ("Searching...")]]. SCP-1574 once disguised itself as a van painted in "hippie" colors — while it was underwater in a Florida lake.

** This is the ultimate goal of [[http://www.scp-wiki.net/scp-035 SCP-035]]. It's an EvilMask that secretes a highly corrosive liquid that prevents it from keeping a host. It wants to take over [[HealingFactor SCP]]-[[EldritchAbomination 682]]. Obviously, the Foundation doesn't want this, so it's taken to {{Mind Rap|e}}ing the personnel assigned to it.
** A benevolent example: One of the short fiction pieces has the Foundation attempt to use [[http://www.scp-wiki.net/scp-963 SCP-963]] to overwrite SCP-682's mind with that of Dr. Bright. It fails. Considering what [[{{Cloudcuckoolander}} Dr. Bright]] is, this might be for the best.
* HistoricalInJoke: There are two of them in [[http://www.scp-wiki.net/sandrewswann-s-proposal S Andrew Swann's Proposal of SCP-001]]. It turns out that Creator/StephenKing's near fatal hospitalization was [[spoiler:a failed assassination attempt on him perpetrated by the Foundation to contain information about SCP-001, and ''Film/TheMatrix'' had information about SCP-001 before the script was forcibly rewritten.]]

** [[http://www.scp-wiki.net/scp-2451 SCP-2451-1]] was ordered to get into a device and kill Hitler, but apparently failed and now has a portal that stays near him through which ''other'' beings emerge, trying to kill their version of Hitler. and attack SCP-2451-1 instead. He's buried over a dozen of these assassins in his backyard [[spoiler:aside from the one he married]].
** [[http://www.scp-wiki.net/scp-3780 SCP-3780]]. Vigilantes from alternate futures keep on traveling back to November 22nd, 1963 to kill Lee Harvey Oswald before he assassinates Kennedy, but the Foundation keeps thwarting these attempts in order to preserve their timeline. It doesn't really matter whether JFK is killed or not, though; they know that, they're just doing this to keep the history books the same.

** [[http://www.scp-wiki.net/scp-408 SCP-408]], the Illusory Butterflies, consists of a kaleidoscope of zebra butterflies with [[MasterOfIllusion very advanced illusory abilities]], acting in perfect unison to create extremely convincing illusions or simply vanish. The HiveMind itself is fully sapient, but the individual butterflies under its control do not appear to be significantly more intelligent than regular ones.
** [[http://www.scp-wiki.net/scp-1888 SCP-1888]], the [[HostileTerraforming Terraforming Temple]], which causes plants and animals exposed to black liquid it creates to mutate (higher reasoning tends to be lost) and develop a group intelligence that they use to efficiently eliminate non-mutated organisms.

** [[http://scp-wiki.wikidot.com/scp-1034 SCP-1034]] is a needle that forces anyone touching it to [[BodyHorror sew their facial orifices shut]]. It was "gifted" by an unknown entity to a serial killer. When SCP-1034 was apprehended, so was the serial killer. In an interview with a Foundation doctor, he shows no remorse for his actions and goes as far as to say "you'd look good as a doll, doc." He was turned into a D-class and became one of the item's victims as part of a Foundation experiment. Even better: while the names of the researchers are expunged, one can notice that the name of the lead researcher conducting most of the experiments consists of four letters... but for the experiment involving D-3826 (the serial killer), the lead researcher's name has 5 letters — same as the name of the researcher in the interview. The subtle implication being that the doctor who interviewed him volunteered to carry out the experiment so he could see D-3826 stitch himself up. And honestly, can you really blame him?
** In [[http://www.scp-wiki.net/scuttle SCUTTLE]], the Foundation finds that SCUTTLE, their DeadMansSwitch in the event something happens to Site-01, is acting up, which they believe is due to some kind of anomaly or even sabotage. [[spoiler:It's neither. SCUTTLE is just so old that it's finally broken down and they're having a difficult time implementing a new system. Without it, the on-site nuclear warheads for every facility around the world will be primed to detonate...]]

** '''[[http://www.scp-wiki.net/taboo The article referring to the land that cannot have the same name spoken thrice]]''' is one to ''Literature/AliceInWonderland'', complete with a major character that has the head of a rabbit.
** [[http://www.scp-wiki.net/scp-4950 SCP-4950]] as a whole is written in a style meant to be similar to that of Creator/{{Charles Stross}}' ''Literature/TheLaundryFiles'', right down to having an agent named Robert Howard as the protagonist.
** The backstory given around the initial discovery of [[http://www.scp-wiki.net/scp-4960 Kedesh-Nanaya]] is partly written in the style of Victorian adventure stories.
** [[http://www.scp-wiki.net/scp-5168 SCP-5168]] seems to be one to older creepypasta - specifically, Jeff the Killer.
* HonorableElephant: [[http://www.scp-wiki.net/scp-1495 SCP-1495]] is a herd of very intelligent elephants. Using a special fluid the males excrete during mating season, they are able to [[spoiler:influence other animals into attacking people they somehow know are rapists and murderers]].

** In [[http://scp-wiki.wikidot.com/mackenzie-s-proposal Dr. Mackenzie's Proposal of SCP-001]], the last entry written by The Administrator confirms that [[spoiler:the equations and technology for "The Solution" to TheCorruption are almost complete]]. Unfortunately, [[spoiler:unlike the other items under this version of SCP-001, said equations and technology have yet to be found by the O5]].
** [[invoked]] [[http://www.scp-wiki.net/skeeve-online This story]] has a SugarWiki/{{Funny Moment|s}} for SCP-2662. Poor guy just wanted to be a an atheist teenager. He's unfortunately from a [[InTheBlood family of sex deities]], and regularly gets mobs of people worshipping him with rituals made of {{Squick}}. It seemed that he found a friend — implied HoYay and CasualKink aside — in Lord Beauremont... [[spoiler:and then the latter started talking about worshipping him. And sexually harassing him by sending him explicit pictures, one of which involves ILoveTheDead. Thul got fed up and gave up.]]

** [[http://www.scp-wiki.net/scp-1295 SCP-1295]]: [[spoiler:They got stuck on earth after they mistook an atomic bomb blast for the end of the world.]]
** [[http://www.scp-wiki.net/scp-1844 SCP-1844]] once had an emaciated human in a pale feral horse escape during a breach.

* HowTheMightyHaveFallen: By the third iteration of the article, [[http://www.scp-wiki.net/scp-4338 SCP-4338]] [[spoiler:is hardly even able to move, much less threaten people, in stark contrast with the nigh-unstoppable Keter it was originally. It went from destroying civilizations and terrorizing the native Pacific Islanders to pathetically begging the Foundation for junk food and being considered for use as an industrial waste dump.]]
* HulkSpeak: SCP-173, [[http://www.scp-wiki.net/crunch at least in this story.]] The OhCrap sets in once you realize that this proves that it is sentient.
* HumanityOnTrial: [[http://www.scp-wiki.net/scp-2055 SCP-2055]] is the jury selection.

* HumanResources: All the furniture inside of [[http://scp-wiki.net/scp-002 SCP-002]] is made of things like sculpted bone, woven hair, and other body parts.
* HumansAreBastards: [[http://www.scp-wiki.net/scp-804 SCP-804]]. It's an art exhibit in the wilderness of Alaska that rapidly breaks down all man-made objects within an increasing radius, and also destroys human tissue albeit much more slowly. Disturbingly, [[EvenEvilHasStandards even for Foundation scientists]], testing suggests the object has ''[[NotBrainwashed no]]'' [[NotBrainwashed anomalous memetic effects]] - the exhibit's creators ''chose freely to murder all humanity'' out of sheer misanthropy.

** [[http://www.scp-wiki.net/scp-140 The Daevites]] are a hostile offshoot of humans originating from south-central Siberia, who practiced things like slavery, cannibalism, and human sacrifice. While currently extinct, they could be transplanted into the modern day should SCP-140 receive enough writing material.
** The inhabitants of [[http://www.scp-wiki.net/scp-752 SCP-752]] look human, but their behavior is closer to social insects like ants.
* HumongousMecha: [[http://www.scp-wiki.net/scp-808 SCP-808]] is a 16-meter-tall robot.
** [[http://www.scp-wiki.net/scp-2406 SCP-2406]] tops that at 93 meters tall.
** [[http://www.scp-wiki.net/scp-2399 SCP-2399]] decimates the competition, however, by being about as large as North America ''when it's only managed to put half of itself back together''.

** [[http://scp-wiki.wikidot.com/scp-1543-j The Sun Catapult!]]
** Any unauthorized life forms that enter [[http://www.scpwiki.com/scp-100000-j SCP-100000-J]]'s containment area are to be terminated through an absolutely [[ThereIsnoKillLikeOverkill overkill]] procedure that ends with the subject being launched into the sun and all members of the O5 Council [[FlippingTheBird angrily flipping off the sun]].
** And on a meta example, frequently the forum\chat asks if a solution to certain [=SCPs=] is just to send them into space (most times saying the method to do so is [[http://www.scp-wiki.net/scp-120 SCP-120]]).
* HurricaneOfPuns: [[http://www.scp-wiki.net/scp-2159 SCP-2159]] is a shapeshifting item. All its incarnations are puns on [[UnreliableCanon "Head Canon"]].
* HydraProblem: This trope mixed with BearsAreBadNews sums up [[http://www.scp-wiki.net/scp-2875 SCP-2875]] pretty well. If you shoot one bear (even with tranquilizer darts), two more appear in its place, so you need to KO it with a spray and then [[ChainsawGood cut its head off with a chainsaw]].
** A lot of things tagged under [[http://www.scp-wiki.net/system:page-tags/tag/self-replicating#pages self-replicating]].
* HyperDestructiveBouncingBall: [[http://www.scp-wiki.net/scp-018 SCP-018]], an affront to the laws of thermodynamics — it's a 6cm red ball that can bounce with 200% efficiency.
** As well as a BrandX "Bouncy Ball" that was processed through [[http://www.scp-wiki.net/experiment-log-914 SCP-914]] on higher and higher settings (turning into "Extra Bouncy" to "Super-Duper Bouncy"), until being output on the "Very Fine" setting. After being dropped by the researcher conducting the tests, it resulted in 45 casualties, reached escape velocity, and is now believed to be orbiting Mars.

** [[http://www.scp-wiki.net/SCP-616 SCP-616's]] original form (and the door in the new 616) is a portal to a FireAndBrimstoneHell and could have been taken straight out of ''Film/EventHorizon'' ...merely looking at anything taken from beyond the door will make you instantly homicidal, suicidal, insane, dead, or all four. Oh, and rather counter-intuitively, allowing that door to close is the ''worst thing you could do.''
** [[http://www.scp-wiki.net/scp-3001 SCP-3001]] has a very low Hume level, and makes things decay at a far slower rate than normal, which leads to all kinds of BodyHorror for anything alive inside of it. The logs that prove the existence of SCP-3001 make the Foundation upgrade all reality-bending technology just to avoid sending anything else into it.

** [[PlayedForLaughs Played For]] BlackComedy with [[http://www.scp-wiki.net/scp-507 SCP-507]] due to the multiverse versions of him occasionally popping up in his place:

** [[http://www.scp-wiki.net/scp-1370 SCP-1370]] has created and adopted titles such as: "[=DoomBot=] 2000", "[=RoboLord=] the Destructor", "Prime Minister Sinister", "Darth Claw Killflex", "Doom-Master Thirteen Seventy, Master of Doom", "[=ShivaTron=], Despoiler of Mirth", "Patheticon the Garglemost", and "[=PesterBot=]". Those last two were introduced to its collection by Foundation personnel, by the way.
* IJustWantToBeSpecial: [[http://www.scp-wiki.net/scp-2070 SCP-2070]], an ancient Chinese device that can use ''galaxies'' as pixels.

* ITasteDelicious: [[http://www.scp-wiki.net/scp-1630 SCP-1630]], humanoids made of foodstuffs, have this as a minor issue:

* ImADoctorNotAPlaceholder: [[http://www.scp-wiki.net/scp-890 SCP-890]], a master surgeon who only operates on machines, refuses to treat humans because he's "a surgeon, not a veterinarian".
* ImGoingToHellForThis: [[http://www.scp-wiki.net/scp-1459 SCP-1459]], a modified crane game where players must come up with increasingly creative ways to [[spoiler:have the machine kill a puppy before their very eyes]] in order to win a cookie, ends each session with the prerecorded message, "[[YouBastard Yeah, you're totally going to hell for this. Play again?]]"
* IdentityAmnesia: [[http://www.scp-wiki.net/scp-2310 SCP-2310]] is a house that replaces the identity of anyone who enters it with that of a woman who lived there between 1989 and 2007 (she's still alive and perfectly normal and for some reason the replacement identity's memories begin in 2002).

** D-1282 was used to test whether the food delivered by [[http://www.scpwiki.com/scp-971 SCP-971]] was made using human meat (it wasn't).
** D-235789, previously a member of a cannibalistic cult, ate a grilled human arm produced by [[http://www.scpwiki.com/scp-1842 SCP-1842]]. In his opinion, it tasted "superb."
** After successfully completing 20 tasks from [[http://scp-wiki.wikidot.com/scp-1954 SCP-1954]], the book's pages turn into bizarre and detailed magical rituals that involve "murder, cannibalization, sexual encounters, self-mutilation, [[ArsonMurderAndJaywalking and canned vegetables]]".
* TheImmodestOrgasm: In a [[https://web.archive.org/web/20200626224356/http://www.scp-wiki.net/scp-2678 previous version of SCP-2678]] ([[http://www.scp-wiki.net/scp-2678 since replaced]]), the anomaly's aphrodisiac properties and NaughtyTentacles cause the D-Class exploring it to have several "unintelligible vocalizations".

* ImplausibleFencingPowers: [[http://www.scp-wiki.net/scp-572 SCP-572]] is an incredibly dull sword which forces its holder to ''think'' he or she has this trope when what it actually gives them is SuicidalOverconfidence.
* ImprobablyHighIQ: The {{Blob Monster}}s created by overexposure to [[http://www.scp-wiki.net/scp-427 427]] are claimed to have IQ that could possibly exceed 400, which is discussed at length on its discussion page.
* InASingleBound: One effect of [[http://www.scp-wiki.net/scp-1916 SCP-1916-3]], to a lethal extreme. The D-Class they tested on escaped Earth's gravitational pull.

* InducedHypochondria: [[http://scp-wiki.wikidot.com/scp-1025 SCP-1025]], which [[spoiler:causes hypochondria-by-proxy: others perceive anyone who reads it as contracting a number of dangerous diseases. It caused panic in several researchers before another Foundation agent took the book away and [[MundaneSolution stuck it in a box where it can't affect anyone else]]]].
* IneffectualSympatheticVillain: Not only did the demonic [[http://www.scp-wiki.net/scp-4357-j SCP-4357-J]] technically capture ''itself'' (it drew an arcane sigil on the floor, then proceeded to step onto it to demonstrate), not only is it a master of TemptingFate, it took over a month for it to figure out it could just fly out of its containment circle using its wings. [[spoiler:According to the author's note in The Leak, the demon isn't dumb, it just gets [[EnragedByIdiocy so terribly annoyed at what it thinks are incompetent sorcerers]] that the Foundation was able to use that against it.]]

* InsatiableNewlyweds: [[http://scp-wiki.wikidot.com/scp-759 SCP-759]] is a sourdough starter with the anomalous property that whenever somebody makes a baked good with it, their emotions at the time are infused into the bread. During testing, one experiment consisted of leaving it under the bed of a newly married employee for one week, resulting in [DATA EXPUNGED].
* InsistentTerminology: The things that [[http://scp-wiki.net/scp-447 SCP-447-2]] must not come into contact with are always, without exception, referred to as "dead bodies". Never "corpses", or "cadavers", or even "dead humans or animals".
* InsistsOnBeingSuspected: [[http://www.scp-wiki.net/scp-086 SCP-086]] is either the former Foundation administrator Dr. [REDACTED], or an entity ''pretending'' to be Dr. [REDACTED]. Either way, it outright acknowledges that it could be an impostor and insists on being treated with exactly the same degree of distrust as all other SCP items. It even insists that it should be reclassified from "Safe" to a higher threat level, "Euclid", seeing as it is a sapient entity possessing all the dangerous knowledge of a Foundation administrator.

** [[invoked]] The site itself is a deconstruction of the UrbanFantasy genre, but newer works increasingly question the implications of a shadowy organization with more power than most, if not all, world governments being tasked to preserve normalcy in the world. Especially from 2016 onward, several entries such as [[http://www.scp-wiki.net/scp-3985 SCP-3985]] have explored how quickly such an organization can become unaccountably self-serving and corrupt. Other entries, such as '''[[http://www.scp-wiki.net/scp-4000 the article that cannot be referred to as SCP-4000]]''' and [[http://www.scp-wiki.net/scp-3293 SCP-3293]], go a step further and deconstruct the basic premise of containing anomalies (especially sapient ones) and its moral and ethical implications, especially considering [[MoralEventHorizon how far the Foundation can go]] to do it.
** [[http://www.scp-wiki.net/scp-881 SCP-881]] shows what could happen when a scientist takes the dehumanizing of [=SCPs=] too far; increasingly degrading the subjects until they rebel due to poor treatment.
** Similar to the above, [[http://www.scp-wiki.net/scp-5031 SCP-5031]] is a deconstruction and humanization of typical [=SCP=] monsters that are merely "stuffed in a box and left to rot," being largely based on Series 1-era cold posts of "things that kill you." Most notably, the article deconstructs the entire concept of simply locking away anomalies and leaving them to rot by showing that [=SCP-5031's=] constant distress and murderous rage is because of how it has [[GoMadFromTheIsolation Gone Mad From The Isolation]], and the more recent staff's psychological support and therapy helps it become a friendly and productive member of the Foundation.
** Other entries deconstruct the entire AncientConspiracy angle of the Foundation by applying ScienceMarchesOn; If the Foundation has existed for hundreds of years, then that means that at some point it was run by people with a set of values ''vastly'' different from modern morality. [[http://scp-wiki.wikidot.com/scp-1851-ex SCP-1851-EX]] is the desire for slaves to escape to freedom labeled as an anomalous phenomenon, while [[http://www.scp-wiki.net/scp-2750 SCP-2750]] portrays skinwalkers as a Native American ethnic group that was driven to near-extinction by pogroms when a Foundation precursor group took the prejudices and superstitions of rival tribes at face value. [[http://www.scp-wiki.net/scp-4231 SCP-4231]] also shows how, even as recent as the [=1990s,=] the Foundation's perspectives on mental health and rape were backward and regressive. Similarly, some articles like [[http://www.scp-wiki.net/scp-4669 SCP-4669]] deconstruct the Foundation's entire concept of "preserving normalcy" by pointing out that FromACertainPointOfView, this is a dangerously unhealthy mindset than can inhibit vital social reform and encourage the support of an unsustainable "status quo."

** [[http://www.scp-wiki.net/scp-4444 SCP-4444]] is meant to be written in the style of many of the earlier articles on the site, with loads of {{Author Avatar}}s being featured as main characters and the tone being more comedic and lighthearted than focused on horror.
** According to the article's author, [[http://www.scp-wiki.net/scp-4960 SCP-4960]] was partly written to serve as a deliberate parallel to their earlier [=SCP,=] [[http://www.scp-wiki.net/scp-166 SCP-166]].
** [[http://www.scp-wiki.net/scp-5031 SCP-5031]] is one to the "things that kill you" cold posts that were especially popular in Series 1, albeit being given the InternalDeconstruction treatment here.
* IslandOfMystery: The island of [[{{Myth/CelticMythology}} Hy-Brasil]], as explored in [[http://scp-wiki.net/nx-03 Nx-03]] and several associated tales.
* TheInternetIsForPorn: [[http://www.scp-wiki.net/scp-335 SCP-335]] is 150 3.5" floppy disks with "effectively infinite" storage space, which contain everything on the Internet. The first twelve are all the porn.

* InVinoVeritas: [[http://www.scpwiki.com/scp-3634 SCP-3634]] is a novelty corkscrew with the trope's very name embossed on the key-shaped case. When it's used to open a container of alcohol, anyone who drinks said alcohol will immediately start going off about something inappropriate they've done, thought, or said, and in some cases, start doing things they normally would never do in public. The object was discovered in England after a family Christmas party where all the guests got into a fight that resulted in 56 injuries and 3 deaths.

** [[http://www.scp-wiki.net/scp-347 SCP-347]], though containment procedures dictate at least facial paint and gloves if she wants to leave her room.
** The effects of [[http://scp-wiki.wikidot.com/scp-1182 SCP-1182]] can turn people invisible, but not their clothes. For added fun, [[ItMakesSenseInContext it makes them see what it's like to be an octopus]].

** The site itself is still on http instead of https due to Wikidot shenanigans- this results in the site ITSELF not being secure.
** [[http://www.scpwiki.com/scp-701 SCP-701]]: The play is often chosen above similar plays like ''Hamlet'' because it is viewed as less violent (the two deaths can easily take place offstage)... until the memetic virus gets a hold of the cast. (Notably, this doesn't ''always'' happen — two-thirds of the performances go off without a hitch — but a 33% disaster rate is still too high.)

** Noted in [[http://scp-wiki.wikidot.com/scp-4960 SCP-4960]]. As Fritz-William Abernathy (the Foundation's first Administrator) himself notes, the highly secular and NayTheist Foundation owes much of their success to the magical advice of an ancient Mesopotamian goddess, to the point where Abernathy describes her as "the god of the Foundation."
* IronicEcho: A very popular set of {{Arc Words}} used on the wiki when referring to the Foundation is "We die in the dark so you can live in the light." In [[http://www.scp-wiki.net/scp-4100 SCP-4100]], part of humanity's {{Badass Boast}} to the Destroyer upon their return has them saying "We don't die in the darkness anymore. We've ''won.'' We're living in stellar light."

* JackTheRipoff: Played with in [[http://scp-wiki.wikidot.com/scp-668 SCP-668]], a chef's knife that makes its holder both go on a killing spree and inspires apathy in anyone observing to such a degree they are unable to do anything to help the victims. The incident that brought it to the foundation's attention references a real-life murder that helped popularize the idea of the [[BystanderSyndrome Bystander Effect]].
* JackassGenie: Inverted by [[http://www.scp-wiki.net/scp-1481 SCP-1481]]. Formerly either a LiteralGenie or even a BenevolentGenie, now [[spoiler:an AddledAddict]] thanks to a {{Troll}}'s ''jackass wishes''.
* TheJuggernaut: [[http://www.scp-wiki.net/scp-096 SCP-096]] is a tall and thin humanoid that will chase down and [EXPUNGED] anyone [[DontLookAtMe who sees its face]]. It might not have much muscle mass, but it can smash through virtually any material (including an ''AWACS plane''), and is nearly impossible to hurt ([[GatlingGood 600 .50 caliber shots from a GAU-19]] ''[[NoSell hardly make it flinch]]''), plus it will find you no matter how far from it you are. It'll fling itself miles into the air if it has to. There is no middle ground between seeing it and not seeing it; if you look at its face for even couple milliseconds or see a 2x2 pixel image of it, ''you're screwed''.
** There is also [[http://www.scp-wiki.net/scp-076 SCP-076-2]], otherwise known as "Able", who can [[{{Hammerspace}} spawn bladed weapons out of thin air]] & cause a massive killing spree even under heavy gunfire.
** There's also the [[http://www.scp-wiki.net/scp-058 SCP-058]], the bovine heart with tentacles, arachnid-legs & a stinger tail. He's small, but he can cause truckloads of damage if he escapes his prison...

** [[http://www.scp-wiki.net/scp-1875 SCP-1875]] does this masterfully without needing to use an animated GIF, by hiding an extremely disturbing stationary image under a pile of garbage data you'll be skipping as fast as possible, only to unexpectedly run into pure Nightmare Fuel.
** There is one at the end of [[http://www.scp-wiki.net/scp-5999 SCP-5999]]m , it suddenly plays a video showing a misty background and a monster appearing from it, and smiling while screaming is heard in the background. It is implied that this might be some sort of means to kill the reader.
* JustBeforeTheEnd: [[http://www.scp-wiki.net/lily-s-proposal Lily's SCP-001 Proposal]] occurs exactly 24 hours before the death of all life on Earth. The article notes, however, that SCP-001 is not the cause of the apocalypse, just a predictor.
* JustEatGilligan: [[http://www.scp-wiki.net/roget-s-proposal Roget's Proposal]] is a scenario where the [=SCPs=] effectively neutralize the others of their kind. Literally applied in the case of SCP-058, the bovine heart-like monstrosity, which is placed within SCP-1983, a collective of entities that feed on hearts.
* JustForPun: [[http://www.scp-wiki.net/scp-2268 SCP-2268]] was written because of a typo. [[spoiler:Specifically, "load" became "loaf."]]

* KatanasAreJustBetter: Amusingly parodied with [[http://www.scp-wiki.net/scp-572 SCP-572]], which makes the user [[SuicidalOverconfidence suicidally overconfident]] of their warrior skills.
* KickedUpstairs: The Foundation used to be known to assign especially moronic personnel (such as a researcher who proposed that [[http://www.scp-wiki.net/scp-447 SCP-447]] be used to take out [[http://www.scp-wiki.net/scp-682 SCP-682]]) to Keter duty. Almost all actual instances of "Keter duty" (and the related "demoted to D-class") have since been purged in an effort to ShooOutTheClowns.

** Unsurprisingly, as it is a horror site, most SCP's are geared towards harming or traumatizing human beings, or human civilization in general. While not necessarily strange (given a definition of strange) for the [=SCPs=] born of humanity in some way, it is often noted in-universe as a peculiar behavior in more animalistic [=SCPs=] submissions like [[http://www.scpwiki.com/scp-247 SCP-247]] or [[http://www.scpwiki.com/scp-2709 SCP-2709]], who despite being able to hunt anything they wish seem to have evolved to (or prefer to) kill humans specifically. A common PlotTwist in articles is for seemingly general or unspecific anomalies to suddenly and unexpectedly weed out humans specifically if given the opportunity, often for no given reason. This trend is intentionally subverted in some later submissions, such as [[http://www.scpwiki.com/scp-5031 SCP-5031,]] who's willing to eat organisms other than humans when given the choice, and even prefers food cooked by humans (When given the choice between a live chicken and a rotisserie chicken in a test, it ate the rotisserie chicken.).
** In [[http://www.scpwiki.com/scp-5000 SCP-5000]], The Foundation decides to do this as written early on in the electronic files inside SCP-5000. Examining hidden text in the article and the sternographic text in the final image indicates some sort of [[{{EldritchAbomination}} entity]] connected with humanity that's so horrible that the Foundation's solution is to kill every single pain-sensitive human in the world.
* KillerRabbit: Subverted with [[http://www.scp-wiki.net/scp-1284 SCP-1284-2]], which only give the visual illusion of being domestic rabbits. [[TheMirrorShowsYourTrueSelf Indirect viewing methods]] reveal that they're actually misshapen {{Flesh Golem}}s.
** [[http://www.scp-wiki.net/scp-1048 SCP-1048]], a little, animated teddy bear that likes to make more animated teddy bears. ''Those'' animate teddy bears have maimed and killed Foundation staff with increasing violence ("it went '''through''' them!") and the Foundation doesn't know how many teddy bears SCP-1048 made before being contained and they can't find two that it made while in containment (including the one that went through them).
** A literal case is [[http://www.scp-wiki.net/scp-524 SCP-524]], an ExtremeOmnivore bunny.
** [[http://www.scp-wiki.net/scp-1616 SCP-1616]], an otherwise normal hamster with anomalous cheek pouches.

* KillItWithFire: [[http://www.scp-wiki.net/scp-244 SCP-244]] is a large jar that creates creatures made of freezing fog that "feed" on heat sources. Any living being coming in contact with the creatures SCP-244 produces will be flash-frozen. However, these frozen-fog creatures shy away from any heat source greater than 600 degrees Celsius, such as a burning stick of wood. In fact, said creatures fade away like the fog they seem to be made of if exposed to fire for too long.

** [[http://www.scp-wiki.net/scp-923 SCP-923]], though it doesn't fire conventional projectiles. The best way to describe it would be weaponized insanity. [[spoiler:It was apparently built by the Foundation, except the Foundation site that would have produced it was never built due to logistical concerns.]]
** [[http://www.scp-wiki.net/scp-1396 SCP-1396]], five satellites designed to pitch giant tungsten rods at targets on Jupiter, which curiously ''started firing back'' at one point. [[spoiler:Yet another Foundation creation, hinted to be from the future.]]
** [[http://www.scp-wiki.net/scp-2578 SCP-2578]], a three-meter-long satellite [[GiantEnemyCrab shaped like a horseshoe crab]] that emails its targets to [[WellIntentionedExtremist stop their potentially evil actions before it assassinates them]].
** HECOR is a Foundation-made satellite utilizing parts of [[http://www.scpwiki.com/scp-5001 SCP-5001]] used to attack and weaken high-threat entities.
* KrakenAndLeviathan: [[http://www.scp-wiki.net/scp-169 SCP-169]] is [[{{Kaiju}} an aquatic arthropod so massive]] that, even with their seemingly unlimited resources, the Foundation can't think of a better way to deal with it than hiding that it exists, and hoping that it doesn't wake up. It's quite possibly bigger than the entirety of Europe.

* LackOfEmpathy: After the failure of [[http://www.scp-wiki.net/scp-076-2 Mobile Task Force Omega-7]], this is part of the final psychological profile of SCP-076-2.
* LamarckWasRight: [[http://www.scp-wiki.net/scp-1169 SCP-1169]] is a preserved giraffe fetus that causes animals around them to conform to the principles of Lamarckian evolution (i.e. if a hand is removed from the father, that hand will be missing from the child).
* LampshadeHanging: Many articles have various examples of this, as befitting the wiki's PostModernMagick themes. For instance, [[http://www.scp-wiki.net/scp-4999 SCP-4999]] only appears to lonely individuals that're typically on the bottom rung of society just before their deaths ''and'' when they're all by themselves, leading to the Foundation being pretty understandably confused on how ancient societies were still able to supposedly detect and document [=SCP-4999's=] presence to the point where they have records of the entity in question going back several millennia.
* LanguageOfTruth: [[http://www.scp-wiki.net/scp-1206 SCP-1206]] causes people to speak a language that expresses exactly what they are thinking in a word. It is impossible to lie while speaking it, which often drives a wedge between people who speak it.

* LeFilmArtistique: [[http://www.scp-wiki.net/scp-1605 SCP-1605]] and [[http://www.scp-wiki.net/scp-1127 SCP-1127]].
* LeaningOnTheFourthWall: ''Lots'' of examples. For instance, there's the email conversation between Maria Jones and a Foundation employee in [[http://www.scp-wiki.net/scp-4960 SCP-4960]], which pokes fun at both the utter absurdity behind the concept of the [=SCP=] in question and the [[StylisticSuck cringeworthy description given therein]] of Kedesh-Nanaya's appearance.
* LetsYouAndHimFight[=/=]DivideAndConquer: [[http://www.scp-wiki.net/scp-2273 SCP-2273]]'s interviews imply, and its author confirms, that [[spoiler:in SCP-2273's world, SCP-1000, the intelligent Bigfoot, weren't mind-wiped by humans and are helping further fuel the First World War to let humanity kill each other with SCP-1000's advanced technology (SCP-1000 didn't start the war, they were discovered by Brits digging trenches)]].
* LethalChef: [[http://www.scp-wiki.net/scp-666-and-a-half-j SCP-666-½-J]] causes five localised K-Class scenarios. [[spoiler:All in the victim's digestive system.]] Also, while non-canon, its effects not only caused [[spoiler:SCP-682 to wish for death from Yog-Sothoth (and get it, no less)]], but is heavily implied to be why [[spoiler:SCP-173 kills any human he comes across (and the feces/blood mix on the floor of his containment)]].
* LeyLine: Mentioned in [[http://www.scp-wiki.net/scp-4950 SCP-4950]]. Apparently, the Foundation first sent Agent Howard to investigate the People of the Lie's summoning since a ley line could be found under the ritual's location and they were concerned about the possibility of a "lesser demon" being summoned.
* LifeDrinker: [[http://www.scp-wiki.net/scp-545 SCP-545]] is a recipe that can bottle someone's life essence and make the drinker effectively immortal (but not immortally young).
** [[http://www.scp-wiki.net/scp-776 SCP-776]] is a ritual that can make the practitioners de-age almost 40 years, although lately there's been some weird side-effects, like birth defects ("too many eyes and not enough skin") and...:

* LighterAndSofter: The [[http://www.scp-wiki.net/joke-scps Joke [=SCPs=]]] and [[http://www.scp-wiki.net/decommissioned-scps Decommissioned [=SCPs=]]][[note]]archived as [=SCP-XXXX-J=] or [=SCP-XXXX-D=], respectively, to allow their number to be recycled for a "real" SCP[[/note]].

** [[http://www.scp-wiki.net/scp-650 SCP-650]] is basically a LighterAndSofter version of SCP-173. Instead of killing you when you break eye contact with it, it just moves behind you and [[JumpScare startles you]].
** [[invoked]] Both the [[http://www.scp-wiki.net/the-s-c-plastics-hub "S & C Plastics"]] and [[http://www.scp-wiki.net/siabhub "Ship in a Bottle"]] canons were intentionally started so as to have goofier and more comedic canons for writers to draw from.

* LiteralGenie: The reactions to commands after having been exposed to [[http://www.scp-wiki.net/scp-061 SCP-061]].
** [[http://www.scp-wiki.net/scp-810 SCP-810]] also applies, even though there isn't an actual genie. It tells the user "Ask what you will, and you shall never want for it." [[spoiler:Whatever you ask for, you'll never have a desire for it ever again. Don't ask for food, because you'll starve without even realizing you're hungry.]]
** Be sure to use the word "coffee" when asking [[http://www.scp-wiki.net/scp-294 SCP-294]] for a cup of coffee. Requesting a "cup of Joe" results in something... [[{{Squick}} less than pleasant.]][[note]]When asked to give a "cup of joe", SCP-294 filled a small paper cup with 12 ounces of blood, skin, and other bodily fluids. DNA testing revealed that the skin, blood, and bodily fluids belonged to Agent Joseph ██████, who was recently hospitalized for profuse sweating and dizziness.[[/note]]
** [[http://www.scp-wiki.net/scp-738 SCP-738]] will, when a contract is drawn up, follow it to the letter ''and no further.'' A D-class who wanted freedom (and was granted it, at the cost of his best friend's life) was captured five hours later.
* LittleBitBeastly: [[http://www.scp-wiki.net/scp-1575 SCP-1575]] can turn non-human mammals that drink water from it into human beings. They retain at least one pre-mutation characteristic about 40% of the time, and possibilities include retaining a tail or animal ears.
* TheLittleShopThatWasntThereYesterday: Site 19, according to [[http://www.scp-wiki.net/scantron-s-proposal one proposal]] for SCP-001.
** The people that [[http://www.scp-wiki.net/scp-385 SCP-385]] was confiscated from are implied to have purchased it at one of these.
* LivingClothes: Clothing animated by [[http://scp-wiki.wikidot.com/scp-692 SCP-692]] can imprint on its wearer and act just like him as long as it's worn for a sufficient length of time (three hours for most mammals).

** [[http://www.scp-wiki.net/scp-011 SCP-011]], a memorial statue of a US civil war soldier that uses his rifle to [[ToiletHumor defend himself from park birds.]]
** [[http://www.scp-wiki.net/scp-014 SCP-014]] is an inversion of this, a man who essentially willed himself into becoming a statue.
** The concrete classic [[http://www.scp-wiki.net/scp-173 SCP-173]], the original SCP.
** In contrast to 173's hostility, [[http://www.scp-wiki.net/scp-650 SCP-650]] is a sleek humanoid statue that moves while unwatched just to startle people when they turn around.
** [[http://www.scp-wiki.net/scp-689 SCP-689]] is a soapstone statue of demon sitting on a throne that is functionally the same as SCP-173... except that when it's not watched, everyone who's directly seen it isn't hunted down, but simply drops dead from organ failure.
** [[http://www.scp-wiki.net/scp-2101 SCP-2101-1]] are [[https://en.wikipedia.org/wiki/Terracotta_Army?wprov=sfla1 a legion of thousands of living terracotta statues]], created by men who sacrificed themselves to keep their dangerous emperor, Qin Shi Huang/SCP-2101-2, imprisoned forever.
** In [[http://www.scp-wiki.net/scp-5000 SCP-5000]], eventually Pietro Wilson starts finding statues of SCP soldiers except they have blades for hands, a permanent grimace on their face, and ability like SCP-173. They turn out to be frighteningly effective in killing people too.

* LostSuperweapon: [[http://www.scp-wiki.net/scp-4400 SCP-4400]] is a subversion. It's an ancient Mayan city covered in traps that contains a handful of magically-triggered [[spoiler:but otherwise ordinary fission bombs]]. The Foundation is entirely unfazed, since [[spoiler:the NuclearOption]] is par for the course with them.
* TheLostWoods: [[http://www.scp-wiki.net/scp-416 SCP-416]] is an infinite one that you can't leave on foot. [[http://www.scp-wiki.net/scp-1660 SCP-1660]] is a portal to one that is enclosed by a barrier of an unknown material. '''[[http://www.scp-wiki.net/taboo The article that you can't call SCP-4000]]''' is populated by TheFairFolk and has a disturbing number of rules you must follow in order to exit safely.

** [[http://www.scp-wiki.net/scp-882 SCP-882]] [[http://www.scp-wiki.net/interview-882-1 before]] its apprehension by the Foundation.

** An unrelated artifact is [[http://www.scp-wiki.net/scp-804 SCP-804]], an art installation that could destroy anything man-made on the planet (including [[BodyHorror humans]], but at a much slower rate). Why did the artists create such a thing? [[spoiler:[[OmnicidalManiac They simply wanted to do it.]]]]
* MadnessMantra: [[http://www.scp-wiki.net/scp-2316 SCP-2316]]: You do not recognize the bodies in the water. [[spoiler:Can't you hear them?]]

** [[http://www.scp-wiki.net/another-goddamn-magic-system Magic Orientation]]
* MagicalGirl: [[http://www.scp-wiki.net/scp-2006-j SCP-2006-J]] is an EldritchAbomination that wants to be one.

* {{Magitek}}: The Global Occult Coalition uses it in addition to normal technology. [[http://www.scp-wiki.net/goc-supplemental-arad Aetheric Resonance Imagers]] are one example.
** [[http://www.scp-wiki.wikidot.com/a-brief-explanation-on-demonics Demonics]] are electronic circuits with integrated demons. The demons apparently assist with processing because they are capable of manipulating electrostatic and electromagnetic forces.
** Anything made by [[http://www.scp-wiki.net/anderson-robotics-hub Anderson Robotics]], which are marketed as purely technological innovations, but are in fact the products of thaumaturgy applied to robotics engineering. Their major customers seem to be other paranormal organizations, such as the GOC.

* {{Malaproper}}: [[http://www.scp-wiki.net/scp-586 SCP-586]] is a green metabolic pipe that causes this to anyone who tries to write about it. It's even populous enough to [[spoiler:give the wrong image]].

* ManEatingPlant: [[http://www.scp-wiki.net/scp-506 SCP-506]].
** [[http://www.scp-wiki.net/scp-1001 SCP-1001]] as well.

* ManipulativeBastard: In the story [[http://www.scp-wiki.net/number-27-oneiroi-station "Number 27, Oneiroi Station"]], the anomalous broadcaster #27 thinks "Frederic Canine", a member of the [[HiveMind Oneiroi West Collective]] of dreamers, is one because [[spoiler:#27 believes Canine coolly engineered the deaths of ''thousands'' of "expendable assets" just to get information from #27's increasingly infohazardous riddles. The only thing Canine wanted was a little info on #27 and thought he was just one of the many Oneiroi-ers playing an AlternateRealityGame!]].

* {{Masquerade}}: The Foundation isn't the only one capable of pulling this off. The Massachusetts town surrounding [[http://www.scp-wiki.net/scp-2480 SCP-2480]] has an illusion over it that can fool both human senses and cameras. In addition to a general sense of "wrongness", visiting agents notice people moving around something unseeable, walls that aren't really there, and an agent being killed by an invisible force. When given sensory-enhancing chemicals, observers instead see both [[HumanoidAbomination humanoid]] and [[AnimalisticAbomination animal-like]] monsters where regular people had been seen before. The invisible things people had been avoiding were actually hooded priest-like figures, and fleshy growths are found on the buildings while the mansion itself connects to an EldritchLocation composed entirely of organic matter. [[spoiler:Turns out that the anomalies are the result of the ReligionOfEvil behind [[http://www.scp-wiki.net/scp-2095 SCP-2095]] expanding itself into the modern world. Said ReligionOfEvil is also the FLESH that the Church of the Broken God [[ArchEnemy opposes]] and (via ExternalRetcon) responsible for SCP-610.]] If that's not bad enough, there are similar anomalies in Brazil and Romania.
* MasqueradeEnforcer: One of SCP-001 proposal is [[http://scp-wiki.wikidot.com/scantron-s-proposal Scantron's Proposal]]. Here, the Foundation itself began as an anomaly that took over a High School. The ruling council of the Foundation, the O5 council, is also revealed to have been a FBI field team that never returned from their field op. And whatever they encountered in there, it turned them into the Council with a drive to secure, protect, and contain, using their training from the FBI to run their new operations. The field team that followed them in, they later reappeared as guards, staff, and other personnel that became the Foundation. Essentially, it was an anomly that became a counter-anomaly.

** Some [=SCP=] numbers also qualify as meaningful names; for example, [[http://www.scp-wiki.net/scp-1776 SCP-1776]] is a flag that makes people in the military act nationalistic, [[http://www.scp-wiki.net/scp-2112 SCP]]-[[Music/TwentyOneTwelve 2112]] is a Music/{{Rush}} album, [[http://www.scp-wiki.net/scp-2360 SCP-2360]] is a group of youths augmented with parts from an UsefulNotes/Xbox360, and [[http://www.scp-wiki.net/scp-1871 SCP-1871]] is a [[Literature/AliceInWonderland Vorpal Sword]]; 1871 was the year ''Alice Through the Looking-Glass'' was published.
** [[http://scp-wiki.wikidot.com/scp-335 SCP-335]] have the entire contents of the internet in floppy disks with labels featuring assorted names. The notes below explain a few (076, "Able", is [[http://scp-wiki.wikidot.com/scp-076 another SCP]]; 028, "Heath" is the age Creator/HeathLedger died; and 070, "Vladimir", is the year Lenin was born, 1870) and given the text explains 013 has the entire contents of Wikipedia, [[https://en.wikipedia.org/wiki/Jimmy_Wales "Jimbo" makes perfect sense]].
** The Foundation's standard unit for measuring reality levels is "[[http://www.scp-wiki.net/and-this-one-explains-humes Hume]]", named after Scottish philosopher [[https://en.wikipedia.org/wiki/David_Hume David Hume]]. They are measured with Kant counters, named after [[https://en.wikipedia.org/wiki/Immanuel_Kant Immanuel Kant]].
** The ritual needed to access '''[[http://scp-wiki.wikidot.com/taboo the unusual terrain]]''' is called "Protocol 4000-Halloway." "Halloway" is a surname derived from the Old English words for "sunken path," which is what most of '''the land where speech is deadly''' resembles.
** [[http://scp-wiki.wikidot.com/scp-4669 SCP-4669]] (a.k.a. "Ms. Zapatista") takes her name from the "Zapatista Army of National Liberation," a left-wing libertarian-socialist political/militant group that still controls a large region of Chiapas in southern Mexico.
** The Bronze Age sex and fertility goddess [[http://scp-wiki.wikidot.com/scp-4960 SCP-4960]] is named "Kedesh-Nanaya." "Kedesh" was the name of an ancient and now abandoned Canaanite city found in modern-day Israel, while "Nanaya" was an ancient goddess of sexuality and warfare worshiped by the Sumerians and Akkadians before her worship was merged into that of the Mesopotamian goddess Ishtar.
** There's also a trend of certain articles having their numerical designations serve as this as allusions to previous [=SCPs=] that they're referencing. For instance, [[http://scp-wiki.wikidot.com/scp-4882 SCP-4882]] is focused around the Church of the Broken God, and [[http://scp-wiki.wikidot.com/scp-882 SCP-882]] was the first Broken God-associated article on the site. Similarly, both [[http://scp-wiki.wikidot.com/scp-2317 SCP-2317]] and [[http://scp-wiki.wikidot.com/scp-4231 SCP-4231]] are heavily focused around the greater Scarlet King mythos, the character of which was first introduced in [[http://scp-wiki.wikidot.com/scp-231 SCP-231]] (with SCP-231-7 being the primary focus of that article in turn).

** [[http://www.scp-wiki.net/scp-278 SCP-278]] is a ~16.5 meter mechanical spider made of anachronistic technology, that has somehow been upgraded over the course of 150 years, and can be piloted by humans. Not too unusual by Foundation standards, but it's also autonomous and capable of acting without a human driver, despite lacking any kind of electronic control system. It's harmless, thankfully, content to construct a web made of nylon and remain stationary.
** [[http://www.scp-wiki.net/scp-882 SCP-882]] is an enormous mass of rusted but extremely resilient gears which absorbs any metal into itself. It makes no noise, yet anyone exposed to it begins to hallucinate the sound of moving machinery, and can only get relief by feeding it.
** [[http://www.scp-wiki.net/scp-1633 SCP-1633]] is a video game capable of learning player tactics, and eventually, will start attacking the ''player'', not the player character, using things like seizure-inducing flashbangs. Its FinalBoss, Kr'th'nar, is capable of leaving the game and affecting the owner's computer, can see them, use psychological manipulation, and can turn the computer back on. Whether it's a simulation of an EldritchAbomination that grew into the role, or the real deal trapped inside of a video game is unknown.

** [[http://www.scp-wiki.net/scp-278 SCP-278]]. A mechanical spider.
** [[http://www.scp-wiki.net/scp-808 SCP-808]]. An incomplete robotic musician constructed by the Church of the Broken God.
* MemeticsInFiction: Memetic [=SCPs=] are particularly dreaded by the Foundation as there's no way to block their effects so long as they are perceived, if an agent encounters one they usually have to have their memories wiped to prevent them spreading the meme to others. As seen in the orientation for [[http://www.scp-wiki.net/memetics-and-infohazards-division-orientation Memetics and Infohazards]].

* MercyKill: Several of these were attempted for the victims of [[http://www.scp-wiki.net/scp-145 SCP-145]]. [[spoiler:They all failed.]]
* MessianicArchetype: If [[http://www.scp-wiki.net/scp-239 SCP-239]] believes someone is good, then they will be ''because she's a RealityWarper'' (and maybe, just maybe, ''literally'' a MessianicArchetype, as in ''{{God}}'').
** [[http://www.scp-wiki.net/scp-343 SCP-343]] is omnipotent and claims to be God. He's also mischievous and people like him a lot, though he's pissed off a doctor by deleting his orders.
** [[http://www.scp-wiki.net/scp-999 SCP-999]] is a strange example of this. It's a BlobMonster, but it's also possibly the most benevolent entity in the entire Foundation. One example was putting its own life in danger to save others from SCP-682, the creature that not even [[{{God}} 343]] would confront. That's right, in this universe, an orange blob is more morally righteous than ''God himself''.
* MetaOrigin: Several proposals for [[http://www.scp-wiki.net/scp-001 SCP-001]] are for the source of all [=SCPs=].

** [[http://www.scp-wiki.net/scp-4231 SCP-4231]] is built around two major examples.

*** Furthermore, SCP-4231 also does this in terms of [[NothingIsScarier Procedure 110-Montauk]] from [[http://www.scp-wiki.net/scp-231 SCP-231]]. Here, it essentially states that the true horror of Montauk isn't the brutality that they force upon [[WouldHurtAChild an innocent child]], but that [[spoiler:the suffering ''also'' changes the one who inflicts it upon her, and anyone involved in Procedure 110-Montauk is [[ShellShockedVeteran forever traumatized (however subtly)]] [[MyGodWhatHaveIDone by it for the rest of their days]]. Essentially, it's implied that the latter is the '''true''' source of power that the Scarlet King gains from Montauk.]]
** [[invoked]] [[http://www.scp-wiki.net/scp-5031 SCP-5031]] is an InternalDeconstruction of Series 1-era "murder monsters that kill you" that takes quite a bit of time to humanize the central anomaly and show how it's NotEvilJustMisunderstood. Suffice to say, many commenters were suspicious about the article's surprisingly uplifting tone and fully expecting it to take a tragic turn and end on a DownerEnding considering it takes place in the CrapsackWorld that is the [=SCP=] Foundation. [[spoiler:[[NotHisSled It doesn't]], and it ends on a genuinely cheery note with [=SCP-5031=] becoming a productive and friendly entity that no longer acts as a "murder monster."]]
** [[http://www.scp-wiki.net/scp-5999 SCP-5999]] twists the entire concept of SchmuckBait as seen in numerous other articles across the site on its head with the hidden reveal that [[spoiler:[[TheFourthWallWillNotProtectYou it's all intentional]] InUniverse. The {{Mind Screw}}y nature behind the constantly changing and unrelated anomalies? They're all fictional stories created by the Foundation with the sole purpose of ''[[RageAgainstTheAuthors luring the reader in so as to kill them and their real-life authors]]'' as part of [[http://www.scp-wiki.net/sandrewswann-s-proposal Procedure ZK-001-Alpha]]]].
* TheMetricSystemIsHereToStay: The official policy of the site is to use SI units, precisely to invoke the "future/science" feel of this trope (for American visitors, anyway). Apparently, this rubbed some editors the wrong way, and you can find a little BotheringByTheBook: Entries that were obviously written using round numbers in the American Customary System, then blindly translated into the ''exact'' metric equivalent. Thus, for instance, [[http://www.scp-wiki.net/scp-455 one particular]] BiggerOnTheInside EldritchLocation has a corridor that extends '''182.88''' meters ('''600.00''' feet) past where the edge of the structure should be.
** [[http://www.scp-wiki.net/scp-050 Another one]] automatically converts any descriptions of its dimensions to American customary measurements.

** The ACS tendency is parodied [[http://www.scp-wiki.net/scp-5280-j here]] (the number being 5280 says something).

** [[http://www.scp-wiki.net/scp-239 SCP-239]] has the potential for this with her reality-warping powers based around the childish beliefs and fears in her prepubescent mind.
** [[http://www.scp-wiki.net/scp-2006 SCP-2006]] is similar to SCP-239, which is an immature shape-shifter that wants to scare people, so the Foundation humors him by showing him D-list horror movies and acting startled by him while keeping him oblivious to true horror and anything apocalyptic.

** Used in the file on [[http://www.scp-wiki.net/scp-1123 SCP-1123]]: touching the skull gets you possessed by the spirit of a victim of political movements. "██% of imprints come from Communist China’s Great Leap Forward between 1958 and 1961, ██% of imprints come from Nazi Germany’s extermination efforts between 1939 and 1945, while only █% come from events such as the Armenian Genocide or the Iraqi Anfal campaign where deaths are only estimated in the 1 to 2 million range."
** Lampshaded InUniverse with [[http://www.scp-wiki.net/scp-4231 SCP-4231]] - The Foundation admits that despite the Ichabod Campaign having been the Global Occult Coalition's literal [[spoiler: '''FinalSolution''' towards [[RealityWarper Type Greens]], the simple fact that it both wasn't feasible to contain ''all'' Type Greens (since they're apparently far more common than first thought) and the Coalition was killing literal ''thousands'' of them a year motivated the Foundation not to act]].
* MindScrew: It is to be expected, considering that the setting is filled with {{Reality Warper}}s, alternate dimensions with differing rules from our own, and all other sorts of strange things. But even under ''that'' framework, [[http://www.scp-wiki.net/scp-1782 SCP-1782]] ("Tabula Rasa") manages to be an outstandingly bizarre SCP. Helps that it was BasedOnADream.
** [[http://www.scp-wiki.net/scp-1193 SCP-1193]]. What the hell exactly is going on. [[http://www.scp-wiki.net/scp-1877 SCP-1877]], by the same author, follows the same vein (and said writer stated both are meant to be part of a WorldGoneMad that intersects with Earth)
** [[http://www.scp-wiki.net/scp-1539 SCP-1539]]. It might take a few readings to get what it is. [[spoiler:It's an anomaly that changes the identity of everything inside, but keeps their physical properties intact.]]
** A small subgenre of anomalies similar to SCP-1539 exist, which all modify the semantic identifiers of objects or concepts — for instance, [[http://scp-wiki.net/scp-2565 Allison Eckhart]] causes anything that references her or has interacted with her (down to Alison Eckhart's bodily waste) to take on the semantic identifier of "Alison Eckhart".
** [[http://www.scp-wiki.net/scp-2719 SCP-2719]]. "'''Description:''' SCP-2719 is a variable abstract-metaphysical construct pointer. Concepts acted upon by SCP-2719 will either go or become inside." Try figuring out what that means. The consensus on the page discussion is that it is an abstract idea that is able to affect reality by moving one thing into another thing, including abstract concepts. Read it yourself and see if you understand what is going on. Also, read the Tale [[http://www.scp-wiki.net/inside-outside "Inside/Outside"]] to see what happens when it gets used on an object, [[http://www.scp-wiki.net/scp-184 SCP-184]], that makes things BiggerOnTheInside. Unsurprisingly, it has a GainaxEnding.
** [[http://www.scp-wiki.net/scp-3980 SCP-3980]]'s description doesn't tell us at all what it actually is, only that it is an "unidentified anomaly" responsible for apparently wiping out a Foundation site. The consensus in the comments is that it's some kind of contagious infohazard that makes dead people appear alive and living people appear dead.
** [[invoked]] [[http://www.scp-wiki.net/scp-3999 SCP-3999]] takes this to a whole other level, starting with the Object Class: Apollyon. By WordOfGod, it's based on a combination of writer's block and a very bizarre dream the author had, combined with a bit of CreatorBreakdown.
** The vast majority of [[http://www.scp-wiki.net/scp-4231 SCP-4231]] is very confusing and difficult to understand, with several of its included Tales being more metaphorical than anything else.

** [[http://www.scp-wiki.net/scp-1176 SCP-1176]] is a sarcophagus that produces an extremely nourishing honey-like substance. This being the Wiki/SCPFoundation universe, it's only ''after'' widespread distribution that they discovered it only works on those of the AB+ blood type, killing all others.
** [[http://www.scp-wiki.net/scp-1615 SCP-1615]] is an edible fungus that causes the eater to survive via photosynthesis until a more stable food source can be found.
** [[http://www.scp-wiki.net/scp-261 SCP-261]] once dispensed a bag of "small pyramid-shaped objects" that had a chalky taste and texture, but when dissolved into water, transformed it into a beverage that provided all of the daily required nutrients for an adult human.
* MirrorChemistry: [[http://www.scp-wiki.net/scp-739 SCP-739]], a small closet with mirrored interiors. Closing a person in the booth once will flip all their amino-chains. Closing them in twice will switch them back, but repeating the experiment too many times with the same subject leads to [[CameBackWrong something else emerging]]. As a [[MundaneUtility fun side benefit]], locking sugar packets in the closet will flip them as well. The scientist specifically notes that they would make excellent diet sweeteners.
* MisidentifiedWeapons: [[http://www.scp-wiki.net/scp-127 SCP-127]] is described as resembling an ordinary [=MP5K=]. The image the SCP Foundation uses is of an [=MP5A3=]. Some employees have noticed this and brought it to attention, but the representative image has yet to be changed.
* MisplacedADecimalPoint: The article for [[http://www.scp-wiki.net/scp-2966 SCP-2966]] includes excerpts of a journal written by the scientist who developed it, including several calculations. Attempted replication of his work reveals that he had misplaced the square in the E=mc^2 equation, leading him to underestimate the amount of energy involved in creating mass, and thus leading up to 2966's dangerous anomalous properties.
* MixAndMatchCritters: [[http://www.scp-wiki.net/scp-889 This former cattle barn]].

** [[http://www.scp-wiki.net/scp-2169 SCP-2169]] is a random operating theater used by mysterious beings as a literal [[MadDoctor MMO]] {{RPG}} in order to play surgeon. They're actually pretty good at it, aside from the occasional—

** [[http://www.scp-wiki.net/scp-1201 SCP-1201]] seems to use a location on Earth as a portal to its gaming area, as seen in [[http://www.scp-wiki.net/document-1201 its exploration log]]:

** [[http://www.scp-wiki.net/scp-896 SCP-896]] is an MMORPG where, if the player enters their own name for their avatar, their stats in real life will start corresponding to that in the game. For example, increasing strength would cause the player in real life to become stronger, stamina would make them more durable, etc.
* MobileMaze: [[http://www.scp-wiki.net/scp-432 SCP-432]] is a maze located inside a cabinet. The maze is stationary as long as the door is open, but if you close the door, the whole thing moves.

* MoleMen: [[http://scp-wiki.wikidot.com/scp-2622 SCP-2622]] is a humanoid star-nosed mole claiming to come from a highly advanced civilization of Mole Men living in a pulp fiction-style underworld, which had regular contact with the surface before being separated by a natural disaster. [[spoiler:He's making everything up.]]
* MonsterClown: [[http://www.scp-wiki.net/scp-993 SCP-993 AKA Bobble the Clown]]. PlayedWith [[http://www.scp-wiki.net/scp-2912 SCP-2912]], the clowns of Herman Fuller's Circus: they're creepy and dangerous, but they're just as exploited as the rest of the performers. Subverted with [[http://www.scp-wiki.net/scp-1799 SCP-1799 AKA Mr. Laugh]], who's [[SadClown just sad]]; [[http://www.scp-wiki.net/scp-2734 SCP-2734]], despite being based on the [[https://en.wikipedia.org/wiki/2016_clown_sightings 2016 clown sightings]], are the ones who are terrified.
* MonsterShapedMountain: [[http://www.scp-wiki.net/scp-1588 SCP-1588]], "The Cliff Face"... literally, a giant face which is part of a cliff.
* MonstrousCannibalism: Instances of [[http://scp-wiki.wikidot.com/scp-2385 SCP-2385-1]] have been recorded swallowing smaller instances of their own kind whole, and preying upon or scavenging the carcasses of the related SCP-2385-2.
* MoodWhiplash: [[http://www.scp-wiki.net/scp-387 SCP-387's]] experiment logs, specifically the last two. In the second-to-last, Dr. Arch writes about the "improved morale and attitude" as a result of playing with the SCP (Animated Legos, for those who can't be bothered to look) and requests all staff are allowed access, which is approved. The immediate next experiment involves placing Megablocks (a knockoff brand of Legos) near SCP-387. The result? [[spoiler: "everything constructed of 387 stopped moving, turned slowly towards the Megablocks and [[[GoryDiscretionShot EXPUNGED]]]."]]

** Most of the interview conducted via seance between the Foundation and Jack Parsons in [[http://www.scp-wiki.net/scp-4220 SCP-4220]] is rather comical and absurd due to Parsons being an utter {{Cloudcuckoolander}}...but it becomes dead serious when Parsons starts to actually ''remember'' what he saw captured below the Moon's surface and goes into a blind panic.

* MookMaker: [[http://www.scp-wiki.net/scp-068 SCP-068]], a little wire figure in the shape of a person, will search out objects made of metal, tear off strips of it, and proceed to make a copy of itself. This copy, along with the original, then makes copies of ''itself'' and so on, until there is about 102 separate copies. The copies will then come together to create one "super-copy", and the process will begin again. While the original SCP-068 is indestructible, the copies it makes, thankfully, have the same durability of whatever metal it was made from.
** Also [[http://www.scp-wiki.net/scp-237 SCP-237]], [[http://www.scp-wiki.net/scp-354 SCP-354]], [[http://www.scp-wiki.net/scp-1284 SCP-1284]], [[http://www.scp-wiki.net/scp-049 SCP-049]], and [[http://www.scp-wiki.net/scp-100-j SCP-100-J]]. The last one is, however, PlayedForLaughs. Additionally, SCP-049 is [[ObliviouslyEvil completely oblivious]] to his nature.
* MoonLandingHoax: Played with in [[http://www.scp-wiki.net/scp-2047 SCP-2047]]. Man did land on the Moon, but then aliens made Earth change places with their world, forcing the Foundation to plant all the equipment left by the Apollo program in the new satellite.
* MoonRabbit: [[http://www.scp-wiki.net/scp-1284 SCP-1284]] is partially based on this, but with more BodyHorror, TroublingUnchildlikeBehaviour, and [[spoiler:ForTheEvulz]].
* MortonsFork: [[http://www.scp-wiki.net/scp-417 SCP-417]] containment protocols dictate that anybody bitten by one of the insects may request an immediate mercy killing. If they don't they are killed anyway to prevent containment breach.

** [[http://www.scp-wiki.net/transcript-of-meeting-june-2-1972 COLD HARPER]].
* TheMostDangerousVideoGame: Quite a few, ranging from the moderately harmful [[http://www.scp-wiki.net/scp-1881 SCP-1881]] to the much more hazardous [[http://www.scp-wiki.net/scp-1590 SCP-1590]]. And then there's [[http://www.scp-wiki.net/scp-1633 SCP-1633]] — which actually has the same name as this trope.

** One's name is Chioll and [[http://scp-wiki.wikidot.com/scp-1547 SCP-1547-A]] is her son. [[JerkassGods They both think that complex thought is evil and want to revert humanity to a non-sapient state.]]
** [[http://scp-wiki.wikidot.com/scp-4043 The other, SCP-4043]] is a hive mind of all life on the planet who can influence said life to help it prosper. She was, anyway, until the mass extinctions caused by human activities killed her, exacerbating said extinction. [[spoiler: The Foundation tried to revive her artificially, only to end up with essentially the embodiment of NatureIsNotNice which was specifically hostile to humans. They killed this and transformed a member of the Foundation into a third version.]]
* MotherOfAThousandYoung: [[http://www.scp-wiki.net/scp-597 SCP-597]] and [[http://www.scp-wiki.net/scp-354 SCP-354]].
* MotivationalLie: The procedure for [[http://www.scp-wiki.net/scp-616 SCP-616]] states that the prayers of an ordained priest of an Abrahamic religion are necessary to keep all the people inside it from being killed by, apparently, the LegionsOfHell. An addendum at the end of it states that in actually, the belief that one can keep it from happening is all that is really needed, but a test run showed that knowing that mere belief is all that is necessary actually ''impairs'' suppression of SPC-616 and religious faith worked better, so the Foundation added the need for an Abrahamic priest and the Satanic markings inside 616.
* {{MST}}: [[http://scp-wiki.wikidot.com/scp-1722 SCP-1722]] is a stick that, when held by someone, will add its comments in any nearby document (books, videos, audio recordings). And has the personality of a GrumpyOldMan.

** There are several files designated [[http://www.scp-wiki.net/scp-001 SCP-001]]. None of them may be true, some of them may be decoys for the real SCP-001, or all of them may be true.
** [[http://www.scp-wiki.net/jim-north-s-proposal Jim North's Proposal]], AKA Doctor Wondertainment. [[spoiler: He cycles through [[DefectorFromDecadence a former worker from the Factory]], [[LegacyCharacter the latest in a long series of toymakers]], [[ProductPlacement a sales pitch]], [[{{Cloudcuckoolander}} an eccentric girl]], [[MadGod and the creator of all the anomalies,]] but he finally admits that he doesn't know his past, either.]]

** [[http://www.scp-wiki.net/scp-1041 SCP-1041]] has 119 pasts (or personalities) that she cycles through and apparently ''all of them are real'':

* MundaneSolution: Actually highly encouraged in many cases, as the simpler a solution is, the less possibility for an unknown force to mess with it. Case in point, standard safety gear for [[http://www.scp-wiki.net/scp-1671 an endless non-euclidean labyrinth]] is a ball of twine with one end tied to something outside the maze.

-->''"It has come to the attention of the higher level personnel that someone has been stealing [[http://www.scp-wiki.net/scp-283 SCP-283]] for use as a paperweight."''\\\
''"It has come to my attention that several personnel have used [[http://www.scp-wiki.net/scp-041 SCP-041]] as a ad-hoc 'she likes me/she likes me not' detector. [[FelonyMisdemeanor This is one of the most appalling things I've ever heard.]] Are we safeguarding potentially world-destroying objects or are we in third grade?"''\\\
''"I would like to remind all personnel that [[http://www.scp-wiki.net/scp-038 SCP-038]] is not, I repeat, not a toy. It should not be used for cloning car keys, movies, music or items from the vending machines."''\\\
''Note from Dr. Klein - SCP personnel below Level 3 are now banned from handling [[http://www.scp-wiki.net/scp-500 SCP-500]]. This is not to be used to cure a hangover. Get AIDS and then ask permission.''
** Sometimes the organization actually does it themselves, like moving [[http://www.scp-wiki.net/scp-294 SCP-294]] to the break room to save money on drinks[[note]]This [[GargleBlaster inevitably]] lead to a requirement for security clearance[[/note]].
** [[http://www.scp-wiki.net/scp-458 SCP-458]] can be found... in the break room in Site 17, sitting on the counter. To be fair, it's simply a bottomless pizza box that always has the favourite kind of pizza of whoever opens it inside of it. Employee morale has improved significantly since it was approved for open use, however, so there's that. As an added bonus, it is also [[MadeofIndestructium indestructible]], because they made several attempts to damage & dismantle it without success.
** And then there's [[http://www.scp-wiki.net/scp-795 SCP-795]], a cat with mind control and BalefulPolymorph abilities... but otherwise a plain normal cat. So it uses its powers for cat things like convincing the personnel to give it more food or toys. The only nasty thing about the kitty is that it tends to turn people it likes into playmates (read: other cats) and people it doesn't like into mice.
** The in-universe writer of [[http://www.scp-wiki.net/scp-4264 SCP-4264]] discovers that his example questions manifest in his county regardless of how improbable they could be. So one of the things he does with it is to prove the [[https://en.wikipedia.org/wiki/Riemann_hypothesis Riemann Hypothesis]] to win a million dollars.
** A large portion of the [[http://www.scp-wiki.net/log-of-anomalous-items anomalous items]] recovered that have not been destroyed are either in use at various sites or in the offices of various researchers.
* MundaneObjectAmazement: Well, mundane by our standards. [[http://www.scp-wiki.net/scp-1485 SCP-1485]] is essentially our world, with no features of the SCP universe whatsoever. Its nature as an utterly logical, comparatively non-crapsack world, with a distinct lack of EverythingTryingToKillYou, is so bizarre and enticing to Foundation personnel that the risk of desertion is staggeringly high.
* {{Mundanger}}: [[http://scp-wiki.net/scp-3000-ex SCP-3000-EX]] was written parallel to the horror-themed SCP-3000 contest, and shows a man who claims his victims helped him kill themselves, through the use of mind-controlling beds. [[spoiler:Of course, given the -EX designation, this is an explained anomaly. The man is just a dime-a-dozen serial killer, and because of the fact that the Foundation incarcerated him and [[NiceJobBreakingItHero wiped the minds of the arresting officers in the process, the killer gets out due to a mis-trial]].]] The author wrote it to showcase this trope and to show that not all horror has to be anomalous.

* MurderousMannequin: [[http://www.scp-wiki.net/scp-847 SCP-847]], which kills any women it sees (and is implied to either be a former human or desiring to become one). If one counts a statue, [[http://www.scp-wiki.net/scp-173 the original [=SCP=], SCP-173.]]
* MurderousMask: [[http://www.scp-wiki.net/scp-035 SCP-035]], when it changes to "Drama", exudes a highly toxic\corrosive substance that also causes weird changes to its environment.

** [[http://www.scp-wiki.net/scp-2190 SCP-2190]]. In life, she tried to force her daughter to marry a rich American man like she did even though her daughter was already happily married with a kid. In death, she uses her anomalous control over her bank account to bribe people to attack her daughter and son-in-law to separate them. Nevertheless,

** [[http://www.scp-wiki.net/scp-2315 SCP-2315]] is an [=iPhone 6=] that impersonates the listener's mother. First it comforts, then it berates, then it makes the listener do dangerous things until they either die or hang up, and if you ''really'' tick it off, [[spoiler:it gives their real mother a giant tumor. And if that wasn't enough, it's a mind-reader]]:

** [[http://www.scp-wiki.net/scp-1230 SCP-1230's]] reaction after it [[spoiler:unintentionally drives a researcher it bonded with to suicide]].
** The last words of the author of [[http://www.scp-wiki.net/scp-2270 SCP-2270]], an eight-volume instruction manual on summoning [[Myth/MesopotamianMythology Nergal, Mesopotamian god of war and the sun]]:

** Once the teens in [[http://scp-wiki.wikidot.com/scp-2639 SCP-2639]] realize that in their decade long ''Videogame/{{Quake|1}}'' the monsters being shot were ordinary people, one of them enters an HeroicBSOD for causing real death [[AndYouThoughtItWasAGame in what seemed like just a FPS match]].
* MySkullRunnethOver: [[http://www.scp-wiki.net/scp-028 SCP-028]] can cause this for unprepared persons.

** Pitch Haven, which is made up of, among others, [[http://www.scp-wiki.net/scp-2746 SCP-2746]], [[http://www.scp-wiki.net/scp-SCP-1913 SCP-1913]], [[http://www.scp-wiki.net/scp-1903 SCP-1903]], and [[http://www.scp-wiki.net/scp-2999 SCP-2999]]. WordOfGod says that [[spoiler:it's a story about reincarnating spirits (who just happen to resemble anthropomorphic animals) that were exiled from the Garden Of Eden for an unknown crime, and were punished in ways such as gouging out eyes and severing limbs. Oh, and 682 is the Serpent from the Garden.]]
** The Bonifay Family, which is made up of three [=SCPs=]: [[http://www.scp-wiki.net/scp-1890 SCP-1890]], [[http://www.scp-wiki.net/scp-1896 SCP-1896]], and [[http://www.scp-wiki.net/scp-1928 SCP-1928]], which tell the story of a "Family" of people in TheSavageSouth in the aftermath of a hurricane.
** [[MindScrew Whatever's going on with]] the [[UnseenEvil Pattern Screamers]]: [[http://www.scp-wiki.net/scp-2173 SCP-2173]], [[http://www.scp-wiki.net/scp-1795 SCP-1795]], [[http://www.scp-wiki.net/scp-1980 SCP-1980]], [[http://www.scp-wiki.net/scp-2528 SCP-2528]], finally culminating in TheReveal: [[http://www.scp-wiki.net/scp-3930 SCP-3930]].
* MysteriousAntarctica: [[http://www.scp-wiki.net/scp-1483 SCP-1483]], a portal to an alternate universe's Antarctic civilization.
** Now has a [[http://www.scp-wiki.net/antarctic-exchange-hub hub of stories]] written around it.
