    300-399 
SCP-302 - Ant Sculpture
  • Cruel and Unusual Death: Anyone who touches the sculpture ends up being stung to death by ants over the course of a few days.

SCP-303 - The Doorman

  • Brown Note: Anyone who sees it is instantly terrified.
  • The Dreaded: Not to the same extent as 173, but it still qualifies.
  • Eyeless Face: It doesn't have any eyes, just a really huge mouth
  • Hell Is That Noise: In-universe; people gain an extreme sense of dread whenever they hear it wheezing.
  • Hidden Agenda Villain: What is it doing in that storage room, and why is it stealing things to hide in there?
  • Humanoid Abomination: It's human shaped and insanely terrifying.
  • Lean and Mean: Described as "emaciated".
  • Might as Well Not Be in Prison at All: It isn't so much contained as predictable; the Foundation isn't even quite sure where it came from, they've just developed protocols for dealing with it.
  • More Teeth than the Osmond Family: A major aspect of its scare factor.
  • No Biological Sex: Referred to as "sexless".
  • Noodle Implements: It has a habit of collecting things, which disappear when it teleports away, and SCP speculates that it keeps them in the storage room it has claimed as its own. The items include various chemicals, several sets of surgical equipment, a gasoline-powered generator, a "cryotube", two research cadavers, and a container of powdered coffee creamer.
  • Nothing Is Scarier: Its forte, which is odd because witnesses can always describe it perfectly without having actually seen it.
  • Obliviously Evil: The description reveals that SCP-303 doesn't intentionally try to inflict intense fear in people. Indeed, it actually just teleports away when people see its entire body, implying that the creature doesn't want to be seen and is never recorded trying to cause harm to people.
  • Primal Fear: Causes this in a lot people. One D-class even chose to get herself stabbed to death than go through a door it was guarding.
  • Vader Breath: The only noise it makes is a loud, terrifying wheezing sound.

SCP-306 - The Frogs

  • And I Must Scream: Instances of SCP-306-1 keep their intelligence and are entirely aware of their situation.
  • Festering Fungus: SCP-306 is a fungus that turns infected humans into frog-like animals.
  • Not So Similar: While they appear to be frogs, they correspond to no known species of frog and their internal organs remain similar to those of humans.
  • The Virus: Anyone infected by the fungus remains extremely infectious after turning into a frog.

SCP-307 - Carnivorous Ivy

  • Exactly What It Says on the Tin: It's a species of ivy that feeds on animals.
  • The Immune: It is highly resistant to any attempt at poisoning it.
  • It Can Think: It appears to have a rudimentary form of intelligence, as it will grow three vines rapidly towards a nearby animal in order to trap it and then feed on it.
  • Kill It with Fire: This is the Foundation's primary means of killing it wherever it is found.
  • Vampiric Draining: Upon ensnaring a victim, it will liquefy and drain their internal organs and blood.

SCP-308 - Aztec Burial Sarcophagus

  • Back from the Dead: It is able to resurrect dead organisms that have intact hearts, as shown with one of the test subjects, an agent, who died in the line of duty.
  • Beat Still, My Heart: An intact heart placed inside the SCP will continue to beat, even without a body to contain it.
  • Nigh Invulnerable: Any living thing placed in the SCP cannot be killed as long as their heart remains intact. Once the heart is destroyed, they die and decay normally.

SCP-309 - The Plush Toy

  • And I Must Scream: Anyone who's turned inside-out by its effect cannot be changed back and are left in constant pain. Fortunately, some of them actually die.
  • Body Horror: Anyone who presses it against their skin is violently and painfully turned inside-out.
  • Creepy Doll: If the fact that it turns people inside out wasn't enough, it's pretty darn weird looking, especially since it's inside out too.
  • Cute Is Evil: Kind of. It's an Ugly Cute plush toy that turns people inside-out, but it doesn't appear to be actively malevolent. Or alive.
  • Living Toy: Averted. Unlike most of the creepy toys from the SCP Foundation, it does not appear to be alive.
  • Painful Transformation: Being turned inside-out.

SCP-310 - Eternal Flame

  • An Arm and a Leg: An agent who was accidentally exposed to the candle's flame had to have his arm removed below the elbow to save his life.
  • Cruel and Unusual Death: If a person gets a body part exposed to it, they will slowly burn to death unless the affected part can be amputated, as the flame cannot be put out by any means.

SCP-312 - Atmospheric Jellyfish

  • Combat Tentacles: After SCP-312 sucks a victim into the air with its atmospheric vortex it stings it with its tentacles and paralyzes it, then digests it.
  • Living Gasbag: SCP-312 is a large jellyfish-like creature that floats in the air by heating atmospheric gasses within itself. It can release water vapor and control air currents to create a cloud around itself as camouflage. It hunts humans and floats above them. If the human looks up at the creature it will suck the human up into itself with a wind vortex and consume it.
  • Very Loosely Based on a True Story: Sightings of so-called "atmospheric beasts" are actually quite common in real life, though there are no reports of them actively harming humans. They are often described as resembling giant, flying sea creatures, not unlike jellyfish.

SCP-313 - Powerful Hand Dryer

  • Blown Across the Room: Or rather across the country; it has a chance of producing superheated plasma that propels it over massive distances.
  • Nigh Invulnerable: It's practically immune to any damage.

SCP-314 - Motion-Seeking Blade

  • Implausible Fencing Powers: Will neatly slice anything that enters its "kill radius". Tennis balls? No problem. Bullets? Easy. Hundreds of gallons of water? The blade whirls around so fast, that it actually dries the area immediately surrounding the blade, effectively "cutting" through the water!
  • "Instant Death" Radius: First established as a 50 meter radius. When someone got skewered by toeing the 50-meter line, it was later amended to "approximately 50 meters". Now, it's somewhere between 50 and 52 meters, just to be on the safe side.
  • Non-Indicative Name: It's actually shaped like an obelisk, rather than a conventional blade.
  • Parrying Bullets: Can hit bullets and other fast-moving targets, though this may cause it to have to break the sound barrier or exist in multiple places at once.
  • Sharpened to a Single Atom: The blade is described as "sharpened to a molecular level".

SCP-319 - A Curious Device

  • Apocalypse How: A solid X-4 Universal Annihilation held back by kludged Victorian-era technology. The horror angle comes from it being based on the possibility that such a thing could actually occur: a vacuum metastability event would spread through the universe at light-speed and rewrite its fundamental forces.
  • Asshole Victim: SCP-319's creator, Sir Bandon, was a racist Insufferable Genius in his entries, just in case you felt bad about him vaporizing himself with his own creation.
  • The Cameo: The fellow explorer Sir Bandon mentions corresponding with is almost certainly SCP-1867, Lord Blackwood, back when he was human.
  • Continuity Nod: To SCP-1867 (though the name is redacted). According to Word of God, it's also in the same mythos as "He-Who-Made-Dark"note .
  • Gone Horribly Right: Sir Bandon wanted to travel outside reality and meet the gods face to face. He didn't consider whether he would be able to exist where they are.
  • That Was the Last Entry: It was found with the journal of Sir Bandon Lawhead-Smythe. The journal says how he created it and planned to use it to "open a doorway beyond our universe" so he could "walk across the threshold" and meet some Cthulhu Mythos-type deities. It ends with "Once I have completed writing this entry, I shall don my protective suit, pass through the locks into the airless interior of the vault where the black door awaits me. When I next write in this journal, I shall have traveled father than any other man on the face of this Earth."

SCP-321 - Child of Man

SCP-322 - "Grow Your Own Castle" Kit

SCP-324 - Eulogy Shrub

  • Memory Jar: The shrub's berries each contain a random memory from a dead mammal buried in its soil. Eating a berry allows the subject to experience the memory contained within.

SCP-326 - A Chinese Peasant

  • Harmless Freezing: SCP-326 was a Human Popsicle for more than fifty years. She not only survived, but revived on her own without assistance.
  • Human Popsicle: After being biologically modified, SCP-326 was placed in cryogenic suspension for more than 50 years before being released. As a result, even though she is biologically 65-70 years old, she is more than 120 years old chronologically.
  • Super Strength: SCP-326 can throw 200 kilograms of weight more than four meters. Her strength has not been formally measured and is probably greater than this.

SCP-327 - The Mermaid

  • Green Thumb: Her vocalizations cause algae and plankton within a kilometre of her to reproduce at incredibly high rates.
  • Hell Is That Noise: Her vocalizations have been described as highly unpleasant to listen to, and it also causes audio-visual hallucinations and headaches in humans for 6-12 hours.
  • Our Mermaids Are Different: In this case, she appears to be a hybrid of a manatee and a human.
  • You No Take Candle: She talks like this due to her limited knowledge of English.

SCP-329 - The Cancer Garden

  • And I Must Scream: The five occupants of the room which has been designated as SCP-329 are in advanced stages of cancer and are unable to speak, and are also in great pain. The cancer also never progresses further while inside the room, so they cannot die.
  • Body Horror: Any people inside the room during Event 329-A develop cancer, and after Event 329-A, anyone inside the room who already had cancer has their cancer tumors altered radically.
  • Religion of Evil: The Church of the Gardener appears to worship the cancer caused by the SCP and regularly subjects people to its effects.

SCP-330 - Take Only Two

  • An Arm and a Leg: If a person attempts to remove more than two pieces of candy within 24 hours, they will have their hands severed at the molecular level.
  • But Thou Must!: Testers are unable to avoid reading the note on the candy jar's side, and even if they approach from the opposite direction, they're aware of its request.

SCP-331 - "Tumbles"

  • Animate Dead: When it's placed around the neck of a dead cat, said cat reanimates, and it responds to "Tumbles".
  • Raising the Steaks: It reanimates any dead cat it's placed on as a "zombie cat".

SCP-332 - The 1976 Kirk Lonwood High School Marching Band

  • Brainwashed and Crazy: Possibly. Some members of SCP-332 have occasionally been seen to struggle against an unknown force before falling back in line after their brief moments of distress. It's possible they're just being controlled by another entity.
  • Magic Music: Of a decidedly malevolent kind. Anyone who hears it will attempt to find instruments themselves and join in, becoming very anxious if they can't but instead miming an instrument as they walk with the band. They will then march along until collapsing from exhaustion or hunger, and are then trampled by the band and other hypnotized people. During the first incident, this led to a 40% fatality rate among students and teachers at their school.
  • Obliviously Evil: To the extent that they're capable of thought in their current form, the band is just performing its regular pieces and regular marches for an unusually long period, and they don't seem to notice the people they hypnotize and trample.
  • Oh, Crap!: After standing for thirty years in their original location, the band suddenly vanished on November 2, 2016 and reappeared in a sports stadium in South Florida. 48 hours after each incident, it reappears in a new random location. This led to a jump form Euclid to Keter and the foundation is desperately looking for a way to contain it.
  • Perpetual-Motion Monster: Seem to have had no ill effects from standing in a field for thirty years and, unlike their victims, do not feel hunger or exhaustion from their activities.
  • Teleporters and Transporters: After each new incident post-November 2, 2016, they teleport to a new location every 48 hours.
  • The Virus: Their music acts this way. For every ten people hypnotized into becoming 332-B, the radius their music can be heard at extends another three hundred meters. The band will not stop playing until every 332-B has collapsed or died.

SCP-335 - One Hundred and Fifty 3.5" Floppy Disks

  • Exactly What It Says on the Tin: A set of 150 floppy disks that contains the entire Internet.
  • The Internet: They contain the entirety of the Internet.
  • The Internet Is for Porn:
    • Disks 1 through 12 contain all the porn on the Internet.
    • Also, this:
    Note from Dr. ██████████: I believe I know where all our bandwidth is going at night. Agent ████'s computer privileges should be limited until he either finds a girlfriend or learns some self-control.

SCP-336 - "Lilith"

  • Voice Changeling: She wore a voice modulator as part of her special containment procedures due to the effect her voice had.

SCP-339 - Be Silent, Be Still

  • Combat Tentacles: The SCP uses tendrils to ensnare and kill anything that makes even the slightest sound within roughly 5 metres of it.

SCP-343 - "God"

  • Affably Evil: One perspective of him, anyway. He's affable, but his morality is pretty ambiguous and in the Competitive Eschatology, he's part of the world-ending Big-Bad Ensemble.
  • All-Powerful Bystander: This is actually one of the reasons why the article hasn't been deleted, as—unlike the aggressive, demanding Marty Stu reality warpers like 531-D—"God" makes no demands of the staff and poses no threat to the world at large.
  • Bigger on the Inside: A Foundation Doctor noted that after SCP-343 renovated his cell, it seemed to be many times larger on the inside than when viewed from the outside.
  • Cool Old Guy: He's rather cheerful and pleasant. Personnel who interact with him tend to feel happier afterwards.
  • Enemy Mine: Teams up with Clef to stop 239 in "Unfinished Business".
  • The End of the World as We Know It: He's one of the main players in the Competitive Eschatology canon, as Yahve (or somebody who merely believes he's Yahve).
  • Friendly Enemy: With Clef, in one of the Foundation Tales.
  • God: What he claims to be, at least.
  • A God Am I: He calls himself God, yes. Although he is a fairly benevolent example of this trope (apparently).
  • God Is Evil: In the Competitive Eschatology Canon he wants The End of the World as We Know It, willingly let SCP-231-7 suffer as much as she did and has Bobble the Clown as one of his Horsemen.
  • Grandpa God: If he really is God, since he looks like an older man.
  • Insistent Terminology: He doesn't like the term Reality Warper and prefers the term "Shaper".
  • Might as Well Not Be in Prison at All: It is absolutely impossible to contain 343; in fact, the only reason he remains in captivity is because he seems to like the Foundation.
  • My Species Doth Protest Too Much: In "Unfinished Business", it's revealed that he's a Type Green, like 239 and 531-D; however, he's also one of the rare few who was able to stop himself from descending into destructive megalomania, hence the reason why Clef hasn't recommended his termination or revealed his true nature. Of course, since there's no canon, the validity of this story is up to you.
  • The Omnipotent: He's described as having apparent omnipotence.
  • The Omniscient: SCP-343 seems to have a knowledge of all topics, allowing him to speak with anyone about anything.
  • Reality Warper: Though he prefers the term "Shaper".
  • Sealed Good in a Can: Subverted. Any attempts to seal SCP-343 are basically futile, and he's only there because he wants to be.
  • The Trickster: Though generally benign, he did once delete a doctor's orders just to annoy him.
  • With Great Power Comes Great Insanity: Theorized to be one of the few reality benders to avert this, which is why he's one of the only ones who hasn't been Clefforated.

SCP-346 - "Pterry" the Pterodactyl

SCP-347 - The Invisible Woman

  • Invisibility: They don't call her the invisible woman for nothing.
  • Invisible Streaker: Her clothes remain visible.
  • Jerk with a Heart of Gold: While she's prone to acts of theft and violent outbursts, she treats people she's left alone with almost as a mother would.
  • Meaningful Name: She calls herself "Claudia" after actor Claude Rains from The Invisible Man.
  • Odd Friendship: She has one with Herr Chirurg/SCP-542.
  • Shameless Fanservice Girl: She doesn't wear clothes most of the time. Not that anyone can actually see anything.
  • Sticky Fingers: She's a kleptomaniac.
  • Stomach of Holding: Undoubtedly related to the above trope, she has trained herself to be able to regurgitate swallowed objects at will. Since anything inside of her body also becomes invisible, this is very useful when trying to steal things.
  • The Tease: She enjoys flirting with male personnel and Dr. Rights requests they refuse her advances.

SCP-352 - "Baba Yaga"

SCP-353 - "Vector"

  • Bad Powers, Bad People: Played with in that Dr. Glass observes and believes that Vector could potentially do good with her Plague Master powers. She could have used her powers to cure everyone's infectious diseases and become a living disease database, but she only cares about the evil applications.
  • Blessed with Suck: Any attempt she makes to manipulate the diseases in her body cause her to get the symptoms of said diseases. Not that she minds.
  • Card-Carrying Villain: She thinks and behaves like a supervillain.
  • Dark Is Evil: According to Dr. Glass, she uses a heavy amount of black for "cosmetic purposes", suggesting that her Vector persona has this theme going on.
  • Deconstruction: Of a supervillain. She's a superpowered sociopath who wants to infect as many people as possible. However, she was subdued and apprehended relatively easily.
  • For the Evulz: When asked why she was collecting diseases and infecting people with them, she responded with "Because I can". Dr. Glass also observes that she has a Might Makes Right attitude.
  • Meaningful Name: A vector in epidemiology is a biological organism that transmits a pathogen, which is exactly what she is.
  • Narcissist: Dr. Glass observes that she has some seriously narcissistic tendencies.
  • Plague Master: She can siphon infectious diseases away from other sources, "store" them in her body and redistribute them as a pandemic.
  • Reality Ensues: Invoked. The Foundation forbids its guards to buy into her supervillain fantasies. If she escapes she's to be subdued; if she refuses to cooperate, she's to be punished; and she's to be addressed not as "Vector", but as "SCP-353".
  • Smug Snake: Believes herself to be a powerful supervillain, yet is very easily subdued when she escapes.
  • The Sociopath: Dr. Glass thinks so, anyway.
  • Wrong Genre Savvy: She believes herself to be a supervillain straight from the pages of a comic book.

SCP-354 - The Red Pool

  • Berserk Button: It was actually playing around with them before they tried to drain it, which it didn't take kindly to.
  • Combat Tentacles: When the monster SCP-354-14 appeared in the Pool, it used 5 octopus-like tentacles to grab several D-class personnel and pull them into the Pool.
  • Eldritch Location: A blood red pool that's sentient, as well as the fact that it can spawn otherworldly things from itself.
  • Genius Loci: It'sbasically all but directly stated that the Pool itself is sentient, and it's angry.
  • Hold the Line: How the Foundation is forced to deal with the Pool and its periodic emergent monsters. A more definitive solution still hasn't been found, and worse yet, the Pool is expanding.
  • Immune to Bullets: At least three of the monsters that have come out of SCP-354 have been effectively immune to bullets, including SCP-354-2 ("virtually bulletproof"), SCP-354-4 ("Gunfire caused very little physical harm and was highly ineffective") and SCP-354-16 ("Gunfire proved mostly ineffective against its hide.").
  • Invisibility: SCP-354-18 was one of the entities that came out of SCP-354. It was a Terminator-style robot with a cloaking device that made it invisible to human sight.
  • Kill It with Fire: SCP-354-2 was a bear-sized creature covered with razor-sharp spines. After it came out of SCP-354 it proved to be Immune to Bullets and had to be destroyed with napalm.
  • Mind Rape: When the Foundation tried to drain it, it responded with this. Frustratingly, the post-incident interviewers don't seem to understand this.
  • Monster of the Week: Dangerous creatures emerge from the pool at various times, and their appearances and capabilities all vary, from SCP-354-4 (a humanoid reptillian) to SCP-354-3 (a large black sphere that emits concentrated beams of radiation) to SCP-354-6 (an ordinary man of Indian decent).
  • Portal Pool: It's essentially a portal to another dimension.

SCP-355 - The Serrated Lawn

  • Agony of the Feet: Anything that steps onto the "grass" with inadequate foot protection has their feet pierced by the "grass" blades, and said blades embed themselves as well, making it difficult for the victim to leave.
  • Kill It with Fire: The "grass" can be destroyed with fire.
  • Vampiric Draining: The "grass" blades siphon bodily fluids through a victim's feet.

SCP-359 - The Hawk

  • Living Statue: It's a living metal sculpture of a red-tailed hawk.
  • To Serve Man: After it was contained, it began killing and eating D-class personnel who entered its enclosure during restricted hours.

SCP-363 - Not Centipedes

  • Creepy Centipedes: These look like normal giant centipedes in the light. When the lights turn off, they grow to massive sizes and become hostile. Even worse, they can turn humans into Body Horror centipedes!
  • Kill It with Fire: SCP-363 is scared of fire, and Foundation troops are issued flamethrowers to use against them. After one containment breach, the site where SCP-363 was being held was firebombed in order to destroy them.

SCP-370 - A Key

  • These Are Things Man Was Not Meant to Know: It's a highly contagious infohazard, and knowing anything about it other than that it is a key leads to infection, which can lead to either suicide, murderous rampages, or casually mentioning infectious SCP-370 information to other people.

SCP-371 - Macrovirus

  • Chest Burster: After SCP-371 infects a victim with its genetic material, new SCP-371 specimens are created inside the victim's abdominal cavity. Once the specimens grow to a length of 20 centimeters they burst out of the victim's body, causing severe trauma (including internal injuries, serious bleeding and death).
  • Face Full of Alien Wing-Wong: SCP-371 reproduces by inserting its genetic material into an animal. The genetic material takes over the victim's cells and causes them to produce SCP-371 specimens. When the specimens become large enough, the next time the victim enters an aquatic environment they use a Chest Burster technique to leave the body.

SCP-372 - Peripheral Jumper

  • Don't Look at Me!: Although it's not hostile about it... unless you confine it such that there are no blind spots at all for it to hide in, then it'll go out of it's way to make them.
  • Eye Scream: SCP-372 is an example of He Who Must Not Be Seen and tries to avoid being seen. During one experiment where it was released into a room with 4 human observers, it attacked one of them and caused them to lose an eye so they couldn't see it.
  • Gaslighting: It was first discovered hanging around a patient complaining of hallucinations. Unfortunately, SCP-372 wasn't a hallucination, and thus the patient wasn't helped by any sort of treatment. By the time SCP-372 was captured, the patient had actually gone insane due to stress.
  • He Who Must Not Be Seen: It constantly moves out of line of sight.
  • Spider-Sense: In place of eyes and ears, it has a sensory organ that allows it to predict where a person is going to look so it can move out of the way.
  • Super Reflexes: How it stays out of sight.

SCP-378 - Brainworm

  • Creepy Centipedes: SCP-378 are centipede-like creatures that can enter a human being's skull and occupy the frontal lobe of the victim's brain.
  • Healing Factor: When SCP-378 occupies a human being's brain, the host gains the ability to almost instantly regenerate physical damage. In one case a host tore off his own arm and attacked using it as a weapon. When he pressed it against his shoulder, it re-attached immediately.
  • Kill It with Fire: SCP-378 are almost invulnerable to attack. The only thing that can even incapacitate them is fire. Fire is also effective in suppressing a victim/host's Healing Factor.
  • Puppeteer Parasite: After SCP-378 enters a victim's skull, it gains control of their brain and controls their body. The victim acts normally while under control, indicating that SCP-378 can read the victim's memories and personality.

SCP-387 - Living Lego

  • Berserk Button: Do NOT place any Megablocks near them, or [EXPUNGED] will occur.
  • Living Toys: They're Lego pieces and people that come to life when humans play with them.
  • Self-Duplication: They can produce more Legos, but will only do so when in a specific container. The inverse will also happen if the container is filled with more Legos than it can hold (i.e. the Legos will disappear until the container is filled exactly to capacity).

SCP-395 - The Bottle Baby

  • People Jars: SCP-395 is a human fetus that lives in a specimen jar filled with formaldehyde. It is fed a mixture of milk and blood once per week.
  • Telepathy: Any human female within 5 meters of SCP-395 is put under its telepathic control. She will begin to lactate, remove SCP-395 from its People Jar and allow it to suckle from her.

    400-499 
SCP-400 - Beautiful Babies
  • Death of a Child: SCP-400 infests and kills babies, then uses Mind Manipulation pheromones to make their mothers think they're still alive.
  • Eye Scream: SCP-400 is an anomalous form of the common pillbug that enters the body of a human baby by burrowing through its flesh. One possible point of entry is the baby's eyes.
  • Face Full of Alien Wing-Wong: SCP-400 reproduces by touching a human woman's skin. This causes the woman to become pregnant with more examples of SCP-400 and eventually give birth to them.

SCP-401 - A Palm Tree

  • Attempted Rape: Implied when it's stated that during its male reproductive phase, it'll attack human females in order to reproduce.
  • Body Horror: It's a eucalyptus tree made of human biomass.
  • Eyes Do Not Belong There: It has eyes growing on the end of each finger.
  • Gender Bender: A particularly squicky example. Although SCP-401 is genetically male, it will grow fully formed female reproductive organs in its hands once it goes into bloom, then will undergo menstruation after five days before developing male sexual organs in their place.
  • Meat Moss: Literally. It's a eucalyptus tree composed of human body parts.
  • Monster Is a Mommy: SCP-401 has produced at least two offspring through artificial insemination. One was a normal, though myopic, baby boy born to a human mother. The other was when the tree itself was inseminated, which caused the arm to become pregnant and then hurl a bladder containing a fetus. This grew into a tiny seedling version of SCP-401, but it died of malnutrition a week later.
  • Multi-Armed and Dangerous: Its branches are all made of arms, some of which split into two or three forearms at the elbow.
  • Too Many Mouths: Each of its roots, which are really esophagi, ends in a fully formed mouth.

SCP-403 - Escalating Lighter

  • Serial Escalation: It's in the name. It's a lighter that produces a larger flame every time it is activated within 24 hours.
  • Stuff Blowing Up:
    • When a D-class attempted to light it for a third time in 2 hours, an explosion of superheated gas and plasma was produced that damaged the flame-resistant plating on the walls and destroyed the monitoring equipment, but left the lighter and its holder unharmed.
    • When a D-class attempted to light it for a fourth time, an explosion was produced that had a magnitude of 10 MT (megaton) of TNT. As before, the D-class was unharmed.

SCP-405 - Telepathy Virus

  • Driven to Suicide: SCP-405 is a contagious effect that causes the victim to gain the power of uncontrollable Telepathy. The constant mental "noise" and resulting sleep deprivation cause most victims to attempt suicide.
  • Telepathy: A person affected by SCP-405 will be able to hear the thoughts of any other human within a specific radius, ranging from 200 meters to several kilometers away.

SCP-408 - Illusory Butterflies

SCP-409 - Contagious Crystal

  • Body Horror: Any living thing that touches it is gradually converted to crystal, and the process is described as being extremely painful. Even amputation of the affected areas will not stop it.
  • Exactly What It Says on the Tin: It's a crystal that turns any non-granite matter into more of itself. However, the effect is far more serious in organic matter.

SCP-410 - Editor Beetles

SCP-412 - Mutagenic Mirror

  • Body Horror: Each time a subject views themselves in the mirror, they suffer progressively worse bodily changes. The changes start out with enlarged lymph nodes, a facial rash, and skin discoloration. They eventually progress to an expanded ribcage, mouth cysts that force the jaw to stay open, and problems with the immune and reproductive systems.
  • Magic Mirror: Anyone who looks into this mirror suffers progressive body changes. If they live long enough, a cavity forms in their chest and a small humanoid creature appears in the cavity.

SCP-413 - Endless Garage

  • Alien Geometries: SCP-413 regularly changes its interior dimensions to cause people inside of it to become lost. Because of this, any Foundation personnel who enter SCP-413 are required to use GPS or safety lines to find their way.
  • Bigger on the Inside: Foundation investigation has established that the interior of SCP-413 is larger than the building's external dimensions.
  • Brown Note: SCP-413 gives off a low-frequency sound inside itself that harms human navigation abilities, balance and short term memory. Prolonged exposure can cause nausea, dizziness, vomiting, vertigo, anxiety and claustrophobia. Luckily, the effect will wear off after the victim leaves SCP-413.
  • Genius Loci: SCP-413 is a sapient parking garage which can change its internal layout, and also change the painting on its insides to spell out words for communication. It uses its abilities to play pranks on people, and also to punish vandals by trapping them for months in an ever shifting labyrinth.
  • Mobile Maze: SCP-413 changes its internal dimensions and uses a low-frequency sound that makes it hard to navigate to trap people inside itself for variable lengths of time, from twenty minutes to more than three months.

SCP-415 - The Harvested Man

  • Body Horror: SCP-415 is a human being who has been physically altered so it is easy to surgically steal his organs.
  • Healing Factor: SCP-415 heals from damage at an accelerated rate and is able to re-grow lost internal organs.
  • Year Inside, Hour Outside: Occasionally SCP-415 is taken by unknown means into another dimension and returned after a few seconds. After being returned SCP-415 says he spent a considerable period of time in the other dimension, up to several years in some cases.

SCP-416 - Infinite Forest

  • Alien Geometries: It's a forest that cannot be left on foot once inside it, and when several D-class personnel were tasked with going from one end to the other, their movement speed relative to the area outside the SCP decreased dramatically as they ventured deeper into the forest, despite them maintaining a constant speed.
  • Misplaced Wildlife: A plant version; the forest contains several species of tree that are native to other parts of the world, and the Foundation is trying to understand how they got there in the first place.

SCP-417 - The Plague Tree

  • Bizarre Alien Reproduction: Anyone who opens SCP-417's fruit will be attacked by the insects contained within. In 45% of these cases, the affected person will die after a few hours, and a new tree will grow from where their body used to be.
  • Body Horror: In 50% of cases where a person has been attacked by one of the SCP's insects, they begin expelling flesh after 2-24 hours.

SCP-418 - The Human Jigsaw

  • Beat Still, My Heart: His heart has been removed and has been designated SCP-418-1. It is used by the Foundation as a means of keeping him under control.
  • Detachment Combat: Primarily used for utility in his career as an industrial saboteur rather than combat. Although in his interview log, he tries to escape after being outed by throwing his intestines at Dr. Lee, which then strangle him.
  • Magical Native American: He's of Native-American decent.
  • The Mole: He's working for someone else, but refuses to say who. Not that the Foundation wasn't able to figure it out anyway, but they won't tell us either.

SCP-419 - Window to the World

  • After the End: Based on observations made through SCP-419, a war occurred and the city was devastated, with buildings burning and reduced to rubble.
  • Alien Geometries: A cityscape can be seen through SCP-419. The buildings are similar to those of the Victorian Era on Earth but appear to be unusually twisted or warped and based on non-Euclidean geometry.

SCP-420 - Aggressive Skin Condition

  • Body Horror: Anyone drinking SCP-420-1 (the liquid inside SCP-420) will suffer six stages of progressive body changes. The changes include finger nails, toenails and skin becoming brittle and growing at an increased rate, skin cancer, skin, hair and mouths growing in random locations, and the victim's skin killing and eating other creatures.
  • Kill It with Fire: When a person who drank SCP-420-1 reaches the sixth stage of infection, they start growing rapidly and must be incinerated before something horrible occurs.

SCP-421 - Shoal of Driftwood

  • The Assimilator: It tries to incorporate driftwood into itself whenever it can, and it attacks and sinks ships for this purpose.

SCP-423 - Self-Inserting Character

  • "Blind Idiot" Translation: When inserted into the German edition of Mein Kampf, Fred's additions are noted to contain a number of grammatical and stylistic mistakes.
  • Coconut Superpowers: In a weird case of this, Fred can only edit the text in a story, so when he was sent into an old issue of X-Men, he took the form of a mutant whose powers, coincidentally, happened to make him invisible and inaudible.
  • Divide by Zero: An evident risk the Foundation is intent on avoiding. Not only is any attempt to cross 423 with any SCP that exhibits literary manipulation or effects not even considered, but even a proposal to have him enter a perfectly normal book involving a character who can, themselves, enter works of fiction was summarily rejected.
  • Gender Bender: In one case, the Foundation decided to force Fred as a main character by writing a story in a fantasy world where all people were female except for a legendary hero drawn from another world. The only change Fred made was that one of a queen's servants was now named Frederica.
  • Her Code Name Was "Mary Sue": Averted, due to his apparent desire to simply witness literary events in person Fred typically casts himself as a minor character, and in some cases writes himself out of the story's main drama (such as in 12 Angry Men, where he is a guard "disappointed to be excluded from the jurors' deliberations"). Though he did rewrite an experiment log to describe himself as "ruggedly handsome".
  • Might as Well Not Be in Prison at All: He's managed to make appearances in at least two other SCP files, meaning he's not exactly all that well contained. The second of the appearances, in SCP-3143, actually reveals that the Foundation has lost track of him.
  • New Powers as the Plot Demands: Sorta. Fred suddenly gains any powers that'd be considered "normal" for him to be a minor character in a story, and only in that story. If he's in Harry Potter, for instance, he becomes a wizard, and in a story with talking animals, he becomes one of the animals.
  • Nice Guy: Fred is polite, courteous, resists the temptation of Mary Sue-ism, and criticizes the Foundation for its We Have Reserves attitude toward D-Classes. invoked
  • One Steve Limit: This is averted if Fred's inserted into a story that already has a character named Fred, such as Harry Potter and the Half-Blood Prince, as he will still be called Fred despite multiple characters now having that same name.
  • Self-Insert Fic: He's a sapient character that automatically adjusts all stories he "enters" to have him featured in some fashion or another, so every story he's been in technically counts as one.

SCP-424 - Nanomimes

  • Blob Monster: SCP-424 is a smooth, black and white gelatinous mass made up of a large number of microscopic organisms.
  • Voluntary Shapeshifting: SCP-424 can take the form (but not the coloration) of any object or creature it has ever seen.

Me, SCP-426 - I am a Toaster

SCP-428 - The Crowd

  • Body Horror: All of the members of the crowd are former human beings who have had every part of their bodies other than their skin replaced with an unidentified material. Even worse, the only reason they're still alive is because they now have crude umbilical cords that terminate in a huge pile of organs found in the center of the room they're in.
  • Healing Factor: Damage to SCP-428’s "crowd" heals at a faster than normal rate. For example, a bullet hole will close up within a few days.
  • Hive Mind: The various members of the "crowd" can think as one, which allows SCP-428 to move quickly in a way that a crowd of normal human beings attached together cannot. It retains some of the talents, skills and memories of the people it absorbs and can use these abilities to add new members or attempt to escape.

SCP-429 - Clockwork Teleporter

  • And I Must Scream: People traveling by it are suspended in endless darkness, paralyzed, for about as long as it would take to walk to their destination on foot. Hunger, thirst, and other issues are not suppressed during this time.
  • Rapid Aging: If someone tries to use it without understanding it, they will still teleport, but when they re-appear they will be dead and in a state of advanced decay. Monitoring devices sent with it on one of these jaunts recorded over 8 months passing. The creator of SCP-429 died of old age after using it too often.
  • Teleporters and Transporters: When someone wears SCP-429 they can visualize a location and be instantly teleported there.
  • Year Inside, Hour Outside: Testing reveals that when SCP-429 is activated without the instinctive understanding it grants, it will disappear and re-appear later within 1.76 kilometers of its previous location between 11 and 17 minutes later. However, approximately 8 months will have passed for anyone or anything attached to it during the teleportation.

SCP-430 - A Peasant's Punishment

  • Clingy MacGuffin: It seeks for a new prisoner once the original dies. And if he leaves somehow, he returns after three hours.
  • Made of Indestructium: It rusts, but it's hard to damage and to get a huge sample. To make things weirder, analysis of the rusted parts show no indication of being anything other than iron.
  • Tailor-Made Prison: It's an individual metallic cylinder that is impossible to leave. It was apparently made for crimes against the Church or feudal authority.

SCP-432 - Cabinet Maze

  • Beast in the Maze: The inside of SCP-432 is an extra-dimensional labyrinth made up of a complex maze of corridors. It's haunted by an unseen monster similar to the Minotaur of Greek Mythology.
  • Bigger on the Inside: SCP-432 is a steel storage cabinet. Inside it is a huge underground labyrinth of steel tunnels.
  • A Load of Bull: It's strongly implied that the labyrinth inside SCP-432 and the monster SCP-432-1 that haunts it are the Labyrinth of Knossos and the Minotaur of Greek Mythology. In the Discussion for SCP-432, its creator admits this to be the case.
  • Portal Door: The doorway in SCP-432 leads to a large underground labyrinth of steel-lined corridors.

SCP-435 - "He-Who-Made-Dark"

  • Casting a Shadow: The indicative name shows it's an entity with powers drawing from the absence of light.
  • Eldritch Abomination: SCP-435-2 is the three-dimensional projection of an extradimensional entity, which looks like a cross between a cephalopod and a higher-order fractal. Anything that it touches gets turned upside down, inside out, or [DATA EXPUNGED] hard enough to trigger nuclear reactions. It's completely invulnerable, and the only chance of containing it is that it generally doesn't move around while the SCP-435 meteorite is brightly lit, lest it intersect water or land and [DATA EXPUNGED].
  • Fantastic Nuke: It's implied to be the true cause behind the Castle Bravo nuclear test at Bikini Atoll.
  • Sealed Evil in a Can: According to the tribe that used to guard it, the meteorite is the lock that keeps He-Who-Made-Dark out of the universe. The Foundation certainly thinks that it could threaten all life on Earth.
  • Weakened by the Light: Which is why it's always covered by ever-lit lamps. And apparently only 90 seconds in darkness are enough for it to unleash its powers.

SCP-438 - Addictive Straitjacket of Espionage

  • Astral Projection: SCP-438 appears to be a normal straitjacket. When it is put on, the person wearing it falls into a coma and undergoes an OBE (Out of Body Experience). Their consciousness can travel great distances instantly and effortlessly, with a full range of sensory perception.
  • Remote yet Vulnerable: While the person wearing SCP-438 is undergoing their OBE (Out of Body Experience), their body is completely helpless and vulnerable to being injured or killed.

SCP-439 - Bone Hive

  • All Myths Are True: In this particular case, it's basically the many disturbing rumors about earwigs, taken Up to Eleven.
  • And I Must Scream: But the insects have probably already eaten your vocal cords.
  • Body Horror: Imagine having your bones start growing and distorting as you slowly turn into an inert mass for a swarm of earwigs to inhabit and slowly eat. All this happens while you are still alive and fully conscious of what is happening.
  • Fate Worse than Death: SCP-439 keeps its victims alive and conscious as it distorts and colonizes their body. Even after the colony finally disbands (ripping the hive to pieces in the process), the hive only truly dies when it eventually starves to death.
  • Insect Queen: The one that founds the Bone Hive, and thus the only one that presents a threat.

SCP-440 - Sand-Based Ecology

  • Combat Tentacles: SCP-440-2 ("Rocktopods") are made up of sand and look like squids or octopi. They can throw rocks with their tentacles.
  • Sentient Sands: SCP-440 is an anomalous form of sand from which certain creatures are created spontaneously.
  • Silicon-Based Life: Several types of creatures are made up of SCP-440, which is an anomalous form of sand. The sand is made up of silica (silicon dioxide).

SCP-441 - Jacob Ram

SCP-446 - Human Mannequin

  • And I Must Scream: From the hints given (e.g. eyes following the nearest person and trying to make eye contact, trying to speak while being vivisected, etc.), the mannequin was originally a human woman who was somehow changed into its current form. It can't communicate with the Foundation doctors studying it, though it very much wants to.
  • Body Horror: SCP-446 was apparently originally a human woman who was changed into the form of a mannequin by unknown means.
  • Healing Factor: According to document Document 446-1-A, any wounds SCP-446 receives will heal within 5-10 minutes with no scarring.

SCP-447 - Ball of Green Slime

  • Depending on the Writer: Due to how the original article was very much written with SCP-447 being a giant Noodle Incident-based Running Gag in mind, the actual effects of SCP-447 coming into contact with dead bodies (or the reason behind the rule of SCP-447 not touching dead bodies) vary considerably between different authors. Most theories are very silly, but some can get quite serious.
  • Noodle Incident: The effects of letting SCP-447 coming into contact with dead bodies was well-documented in its recovery incident, but is completely expunged.
  • Riddle for the Ages: What exactly does happen when 447 comes into contact with dead bodies? What's amusing is that for the most part, 447 is actually relatively harmless and even pretty beneficial for most objects it's applied to (except for dead bodies).
  • Running Gag:
    • "SCP-447 must not come into contact with dead bodies."
    • SCP-447's association with the color green and the smell of mint, and the Foundation pointing it out every single time.
  • Take Our Word for It: SCP-447's interaction with dead bodies was apparently so bad, the Foundation originally classified it as Keter, before downgrading it to Safe.

SCP-451 - Mister Lonely

  • Alone in a Crowd: After coming into contact with [REDACTED], SCP-451 is incapable of seeing, hearing, or otherwise interacting with other humans.
  • The Aloner: What he thinks he is, as he cannot see any other human beings.
  • And I Must Scream: His journals even reference the Trope Namer story and relates it to himself, adding "What's the point in screaming if no one's around to hear?"
  • Bungled Suicide: SCP-451 attempted to shoot himself at one point, only for the bullet to simply phase through him and hit a researcher.
  • It's All My Fault: Blames himself for accidentally killing off humanity, unaware that it's still alive.

SCP-452 - Dreamcatcher Spider

  • Deep Sleep: Humans that have slept in the spiders' vicinity have reported that they had restful sleep, but they also feel "unusual, like [they are] missing something".
  • Exactly What It Says on the Tin: It's a group of black widow spiders able to suppress the dreams of any nearby sleeping humans.

SCP-453 - Scripted Nightclub

SCP-455 - Cargo Ship

  • Alien Geometries: In addition to the ship being Bigger on the Inside, it regularly changes its internal structure in bizarre ways to trap and harm intruders and inflicts audible and visual hallucinations on them.
  • Bigger on the Inside: The ship's internal structures are larger than the external dimensions of the ship, such as a hall inside the ship extending 600 feet beyond the hull and the interior of the ship having 30 decks even though it should only have six.
  • Year Inside, Hour Outside: Experiment Log 455. During the second expedition into SCP-455, two weeks passed inside the ship while 10 seconds passed outside. During the third expedition ten hours passed inside the ship while a few minutes passed outside of it.
  • Year Outside, Hour Inside: Experiment Log 455. During the second expedition into SCP-455, 16 hours passed outside the ship while one minute passed inside it.

SCP-457 - Burning Man

  • Asteroids Monster: Once he reaches a large-enough size, he'll break into two, and then four, and so on. Although they're all hostile to each other.
  • Elemental Embodiment: Despite the name, 457 is less "man" and more "burning". It has no physical body and consists entirely of fire, appearing to be a fire elemental of sorts. Much like fire itself, it seems to have no goal but to spread itself further.
  • Elemental Rock–Paper–Scissors: Consists of fire, is weak to water.
  • Evil Counterpart: It's more or less this to SCP-054, a more passive water being.
  • Evil Living Flames: It appears to be composed entirely of flame, and though it's intelligent enough to communicate with humans (it can do so by writing letters out of its own flames) its goals are limited to simply spreading and acquiring fuel sources. Several wildfires have been attributed to it.
  • Pyromaniac: It's obsessed with burning things and searching for fuel to burn.
  • Weaksauce Weakness: Water, naturally. Its containment procedures include a sprinkler system.

SCP-458 - The Never-Ending Pizza Box

  • Exactly What It Says on the Tin: It's literally a Little Caesar's pizza box (large size) that always has pizza in it. Always.
  • Infinite Supplies: Nobody knows where the [EXPUNGED] the pizza inside comes from. Thankfully, there seem to be no harmful effects from eating it (aside from the usual obesity that comes from eating large amounts of normal pizza).
  • Made of Indestructium: All attempts to dismantle or destroy it have failed.
  • Mundane Utility: It's currently "contained" in the staff break room, and free for anyone who's hungry for some pizza.
  • One-Note Cook: It can make pizza from any chain, with any topping, including homemade pizzas. However, it can only make pizza, and cannot use ingredients that would be indigestible by a normal human being.
  • Supreme Chef: If an inanimate object can be considered a chef, then it qualifies. The pizza it makes is delicious.
  • Your Favorite: Tests show that it seems to read the mind of whoever touches it to create their "perfect pizza", using the toppings, crust, sauce, and cheese they would enjoy eating most. This even works on other SCPs. For example: Able's favorite pizza is apparently a large pizza with meatballs, pepperoni, bacon, Canadian bacon, sausage, hamburger, and thick crust. 040's favorite pizza is a small pizza with extra cheese and a cheese-stuffed crust.

SCP-462 - The Getaway Car

  • Teleporters and Transporters: When someone sits in the driver's seat of SCP-462 and turns the key, they will disappear and turn up near their intended destination a variable amount of time later.
  • Year Outside, Hour Inside: Most people who use SCP-462 for Teleportation remember driving for a few minutes before ending up at their destination. However, they can re-appear up to seven months later.

SCP-466 - Mobile Veins

  • Body Horror: SCP-466 is the animated combination of the cardiovascular systems of four different people, plus the head of the original person. Originally it was the cardiovascular system of one person which somehow became independent of its original body. It obtained the additional three systems by attacking several doctors that were trying to help it after it appeared to die.
  • Combat Tentacles: The vessels of SCP-466's cardiovascular systems (veins and arteries) can be used as tentacles to grasp and constrict. After it acquired additional cardiovascular systems the vessels became more powerful and developed barbs on the ends that can inflict damage.
  • Healing Factor: SCP-466 is noted as being able to heal any damage to itself at an accelerated rate.
  • Kill It with Fire: If SCP-466 breaches containment it is to be suppressed using flame weaponry (e.g. flamethrowers).
  • Retcon: SCP-466's rewrite is one of the most atypical rewrites on the Wiki yet. The original article consisted of everything in the ORIGINAL folder, and the rewrite added the four folders beside it, meaning that the rewrite is more of an external expansion than a full Retcon.

SCP-469 - Many-Winged Angel

SCP-472 - The Bloodstone

  • Terrible Ticking: Anyone within 18 meters of SCP-472 will hear the distant beating of their own heart. Listening to the heartbeat causes negative psychological symptoms. The longer the subject listens to the heartbeat the worse the symptoms become, starting with unease, anxiety and guilt and eventually leading to paranoia, hallucinations and catatonia (with a 76% chance of death).
  • Vampiric Draining: Anyone who goes within 18 meters of SCP-472 will lose up to 1.35 percent of their biomass. It's implied in the article that it's somehow feeding on its victims by draining their blood.

SCP-475 - Pope Soap

  • Body Horror: The SCP is implied to have caused this to D-234, as it is stated that "Subject D-234 was terminated after his skin and eyes [DATA EXPUNGED].".
    Dr. ████: Oh my ███, his skin!

SCP-478 - Tooth Fairies

  • Body Horror: After SCP-478 infects a human victim's mouth, teeth will begin to grow at a tremendous rate. The growth will fill the victim's palate and then spread to the rest of the digestive tract, lungs and underneath the skin.
  • More Teeth than the Osmond Family: Any creature infected by SCP-478 will end up with a literal mouth full of teeth.
  • The Needless: Instances of SCP-478 don't seem to need to eat, sleep, breathe, or even breed.

SCP-485 - Death Pen

SCP-486 - Coatlicue Skin

  • An Arm and a Leg: The SCP is missing her left arm from the elbow.
  • Meaningful Name: Coatlicue is an Aztec goddess who also had her blood emerge in the form of a snake.
  • Noodle Incident: It's not revealed what happens when she suffers from internal bleeding or is going through her menstrual cycle.

SCP-487 - The Impossible House

  • Alien Geometries: Moving or removing any of the supernatural objects inside SCP-487 has variable effects, such as changing the internal structure of the house or causing anomalous events outside of it.
  • Bigger on the Inside: The basement area is larger than it should be according to the house's blueprints. It's a maze of doors, hallways and rooms with no apparent pattern.

SCP-488 - Meteor Attractor

SCP-489 - 1-555-BUG-BASH

  • Animate Inanimate Object: It's a collection of objects used to kill or repel insects that can move around and kill insects.
  • The Assimilator: It seeks to incorporate any nearby bug-killing objects into itself.
  • Big Creepy-Crawlies: Some of the specimens it's collected are even about 4 or 5 metres long!
  • The Collector: It collects the corpses of the insects it's killed and puts them in jars in the van in its center.
  • Dem Bones: The mass' central van contains a human skeleton.
  • Humanoid Abomination: One of its specimens, labelled appropriately "The Bug Man", is a humanoid with the eyes and proboscis of a housefly.
  • Posthumous Character: The SCP's creator is dead.

SCP-490 - Ice Cream Truck

  • Compelling Voice: Or rather Compelling Song. The song it plays compels any nearby people to step into its back one at a time and disregard any warnings.
  • Human Resources: Its "Super Surprise Flavor!" ice cream contains human flesh from the unlucky person it has managed to entrance and capture.
  • It Can Think: It's perfectly capable of operating on its own, and it tried to escape upon being surrounded by Foundation vehicles.

SCP-492 - Animated Cloth Dummy

  • Demonic Dummy: Averted. "Captain Jack" is friendly, helpful, and quite harmless, to the point of being inducted into its Foundation site's staff.
  • Kill It with Fire: SCP-492 is made of cloth, so it is highly vulnerable to fire and can be easily destroyed by flame.
  • Logical Weakness:
    • Because SCP-492 is made of cloth, it is almost immune to physical attacks such as blows. However, its cloth body also makes it very vulnerable to flame.
    • "Captain Jack" also lacks musculature, and so can neither hit hard nor lift anything heavier than a pound.
  • Nice Guy: "Captain Jack" is quite friendly.
  • Pinocchio Syndrome: A test with SCP-978 shows its greatest desire is to become human.
  • The Pirates Who Don't Do Anything: Well it was part of a children's attraction.

    500-599 
SCP-504 - Critical Tomatoes
  • Disproportionate Retribution: They react to groan-worthy jokes by attacking whoever or whatever made the joke. Exposing one to Dane Cook skits in particular causes it to destroy the CD player that's playing back the joke, and exposing another to a mathematics joke causes it to strike so fast that it creates a sonic boom.
  • Eye Scream: One D-class personnel had his right eye destroyed by a piece of tomato when he made a bad joke.
  • Logic Bomb: The bad German copy of the joke from Monty Python's "The Funniest Joke in the World" sketch. Since the joke is that the joke isn't funny, and the joke itself is actually funny, but removed from the context that makes it funny... the tomato exploded.
  • Produce Pelting: These are tomatoes that hurl themselves at anyone who makes a bad joke within earshot.
  • Take That!: Its reaction to Dane Cook and Saturday Night Live sketches.

SCP-507 - Reluctant Dimension Hopper

  • Action Survivor: The man has been in several realities with near fatal conditions. He survives everything these worlds throw at him including fighting a Polar bear bare handed for a moment or two.
  • The Ace: Hilariously, he often arrives in realities with an SCP equivalent to his own. In one, he actually became a very valuable field agent in about 3 months. Upon arriving back to his reality, he details several SCP's that haven't been contained by his reality yet and they are found and captured. He then requests to join his own realities field team which is, of course, denied. It's probably for the best given his unpredictable shifting which could occur in the middle of a mission.
  • Cloud Cuckoolander: He's clearly a bit touched in the head, specially because his powers make him suffer.
  • Dimensional Traveler: Not that he wanted to become one, because he cannot control his dimension travels all. Besides, many of the dimensions he travels to are really dangerous and/or weird.
  • Eldritch Location: He usually ends up in these type of places.
  • Extreme Doormat: The reason he's given so much freedom by the Foundation is because he's completely obedient to their will.
  • I Have Many Names: He'll respond to the names "Tommy", "Steve", "Bruto", "Guy", "Houdini", and "Grabnok the Destroyer".
  • Klingon Promotion: Document 507-3B is a list of the Alternate Universes SCP-507 has been to while in Foundation custody. In universe 7F2-WA3-193, U.S. President Abraham Lincoln was assassinated by his Vice President in order to assume the Presidency. Over time this became a standard procedure in which any qualified candidate could become President by assassinating the current President.
  • Lovable Coward: The attached document implies that he's quite cowardly, but can you blame the poor guy?
  • Mirror Universe: One of the universes he wound up in had a "Church of the Mending God" and a version of the Global Occult Coaliion that worshipped the supernatural.
  • Never the Selves Shall Meet: Interview 507-G documents an aversion, with a twist ending. He also met another version of himself during one of his shifts as well. As well as a female version of himself in a universe where everyone is the opposite sex.
  • Power Incontinence: Has absolutely no control over his "shifts" and when they occur. They can even occur while he is sleeping or in mid-sentence.
  • Properly Paranoid: When two of him show up at the same time, they refuse to reveal which is from a different reality so that the Foundation won't dissect the spare. When one teleports, the other accidentally lets slip a detail that ID's both of them as alternates. The last line of the log is a typical clinical research log indicating that 507's powers do still apply to "severed limbs." The original 507 reappears a few days later, and is never informed about the events.
  • Ridiculously Average Guy: He has no outstanding physical characteristics outside of being slightly overweight.
  • Random Transportation: He has no control over when the shifts happen and where do they take him to. There is a reason he is called the "reluctant" dimension hopper.
  • Running Gag: Pudding. The guy's encounters caused him to have a small sub-plot regarding pudding.
    • He first adopts a full-pudding diet for two weeks after coming back from a world where all the plants scream telepathically when eaten.
    • He then becomes addicted to pudding for a short while after he travels to a dimension full of [REDACTED] that appeared as pudding to him.
    • He then completely averts pudding after traveling to another dimension and experiencing some [DATA EXPUNGED], causing him to return much, much fatter.
  • Silicon-Based Life: On one of SCP-507's trips, he ended up in a dimension with living, moving crystals based on silicon. They're described as looking like crustaceans and may be connected to SCP-440, which also creates crustacean-like silicon-based life.
  • Telepathy: Document 507-3B is a list of the Alternate Universes SCP-507 has been to while in Foundation custody. In universe 9E2-66V-7HG5 he encountered plants that gave off a "telepathic scream" when eaten.
  • Unluckily Lucky: Paradoxically for as many weird Eldritch Locations SCP-507 finds himself in, he never winds up in a location where he would be mortally wounded or instantly killed, like say in the middle of space. He doesn't even manage to ever bring back anything dangerous with him.
  • Unwitting Instigator of Doom: In a deleted SCP, SCP-507 wound up in a game store during one of his trips. He bought a couple of booster packs of an expy of Magic: the Gathering for a couple of agents he knew. The problem was that when they used the cards, in this case, a fireball card, it set the opposite player on fire. Later, when interviewed about the game store, he said he did find it odd that the two guys playing it there were doing so in a steel cage. However, he figured that was just how they played it.
  • What the Hell Is That Accent?: He speaks with an accent of... disputable origin.

SCP-516 - Intelligent Tank

  • Berserk Button: The SCP will kill traitors to its native country on the spot without its usual sense of restraint.
  • Gentle Giant: It's a weapon of war, but is otherwise quite benign when left to its own devices. When SCP-978note  was used to see what SCP-516 desired most, it was shown simply "living" peacefully in a meadow, overgrown with plants.
  • I Am Not a Gun: See above.
  • My Country, Right or Wrong: Traitors to the country of 516's origin are afforded absolutely no mercy.
  • Never Hurt an Innocent: It will protect itself if it has to, but will make absolutely certain to cause as little damage as possible to those that mean it no harm.
  • Sapient Tank: It's Exactly What It Says on the Tin.
  • Take a Third Option: One test involved a D-class personnel suicide-bombing the tank while handcuffed to an unarmed person equipped with a kill-switch that would blow him up if the former ever died. 516 implicitly killed the scientist overseeing the test just as he was issuing instructions.
  • Tank Goodness: Literally. It's a T-55 made in the Ukrainian SSR, and it appears to have a very strong sense of morality.
  • Three-Laws Compliant: If it isn't self-aware, then it's most definitely this.
  • Undying Loyalty: Traitors to the country of 516's origin are afforded absolutely no mercy.

SCP-520 - Knife Switch

  • Big Electric Switch: When activated, it opens or closes the primary power supply circuit of an electrical device somewhere on Earth. This can be anything from a toaster to a fail-safe device in a nuclear reactor.

SCP-522 - Blood-Draining Carpet

  • Vampiric Draining: When a human being stands on the middle of the carpet, it will wrap itself around the person, insert thousands of hairs into the them and drain them of all of their blood in a few minutes.

SCP-523 - The Most Unhelpful Object On Earth

  • Telepathy: SCP-523 continuously gives off a low-frequency telepathic signal that is heard as a "dull ringing sound" by anyone capable of perceiving telepathic communications.
  • Voluntary Shapeshifting: When SCP-523 escapes from containment, it changes its form to that of a useful object. When someone tries to use it for a specific purpose, it changes to another form that's not useful at all for that purpose.

SCP-524 - Walter the Omnivorous Rabbit

  • Autocannibalism: He's so omnivorous that he's even willing to eat himself.
  • Extreme Omnivore: In case the name didn't clue you in, this bunny will eat damn near anything.
  • Hair-Raising Hare: Subverted. Despite being capable of eating anything up to and including SCP-682, Walter is designated "Safe", since he's not actively malevolent.
  • Killer Rabbit: Although he's a relatively benign example. It still says something that even 682 didn't try to attack it, instead just running away up the wall.
  • Trademark Favorite Food: Judging from the experiments with SCP-978, his favorite thing to chew on is granite.
  • Unexplained Recovery: He'll literally just reappear near the spot he ate himself in.

SCP-525 - Eye Spiders

  • Eye Scream: SCP-525 is a creature made of spider-like legs that band together to seek out creatures, extract their eyes and lay eggs in their sockets.
  • Face Full of Alien Wing-Wong: SCP-525 looks like a small starfish. It climbs the body of its victim and extracts one of its eyes, then implants eggs in the eye socket. About 24 days later new SCP-525 hatch from the eggs.

SCP-527 - Mr. Fish

  • Non-Human Head: SCP-527 has a human body, except for his head, which is that of a gold barb fish. Despite this, he can think and speak as well as a human being.
  • Scannable Man: Not a barcode, but a label tattooed on his foot. "Mr. Fish, from Little Misters ® by Dr. Wondertainment".
  • What Kind of Lame Power Is Heart, Anyway?: His only power is that he has a fish head: despite what the Foundation expected, he can't breath underwater, he can't communicate with fish, and he has no other strange abilities.

SCP-529 - Josie the Half-Cat

SCP-530 - Carl the Variable Dog

SCP-531 - Paired Brass Guard Cats

  • And I Must Scream: Anyone who breaks the line of sight between a pair of SCP-531 instances is compelled to look at one of them, and is slowly converted to another statue. They remain conscious and aware throughout this process, and it's indicated that their souls are trapped in the statues.
  • Mundane Utility: It has been proposed that SCP-531 instances could be used in the containment of other SCPs as a type of gate or barrier.

SCP-532 - Frost Bug

  • Body Horror: It's a type of bacterium that causes symptoms similar to frostbite in anyone it infects. The page image even shows a person's hands where the fingers have blackened as a result of the infection.

SCP-535 - Communicative Beaker

  • Rainbow Motif: When certain types of information transmission or storage come within one meter of the liquid in the Beaker, the liquid changes color as follows: red (digital media), orange (radio waves), yellow (sound waves), green (photographic film), blue (text and physical visual imagery), purple (magnetic tape), white (human brain).

SCP-537 - Singing Gramophone

  • Berserk Button: It's not fond of someone interrupting its tracks, throwing childish tantrums with its needle when such is done.
  • Hero-Worshipper: Its greatest desire is to perform "The Rainbow Connection" with Kermit the Frog.
  • Loony Fan: Its favorite soundtrack is from The Muppet Movie, adoring it to the point that a poster has been put up in its containment area, and it dreams of meeting Kermit.
  • The Speechless: It communicates primarily by playing songs. However, it will also raise and lower its needle, once for "yes" and twice for "no", and it uses this method to indicate numbers as well.

SCP-538 - Shadow Spiders

  • Bizarre Alien Reproduction: Shadow spiders reproduce by biting a victim. After about an hour the victim suffers a horrible death and their shadow breaks up into pieces. Each shadow piece becomes a new shadow spider.
  • Weakened by the Light: While in brightly lit areas, shadow spiders shrink at a rate of 2 centimeters per second. When they're reduced to nothing they're destroyed.

SCP-542 - Herr Chirurg

SCP-545 - Liquid Life/Totenkinder

  • Human Resources: SCP-545-B (the titular Liquid Life) required a living human, preferably a child, as one of the ingredients.
  • Meaningful Name: "Totenkinder" literally means "dead children" in German.
  • Would Hurt a Child: SCP-545-A (the titular Totenkinder) has no problem with luring and killing children in order to produce SCP-545-B, and she's been doing it for 800 years.

SCP-553 - Crystalline Butterflies

  • Razor Wings: The wings of adult SCP-553 are 5 millimeters thick and taper to sharp edges. They can attack dangerous opponents by slicing them with their wings, inflicting a wound up to 1 centimeter deep.
  • Silicon-Based Life: SCP-553 have a silicon-based biochemistry and are composed primarily of calcium and silicate compounds.

SCP-557 - Ancient Containment Site

  • Benevolent Precursors: The site was found to contain remains consistent with at least two other SCP's on Level 4, described as "a place for the abnormal", meaning that its Keepers were doing the Foundation's work at least two thousand years before.
  • Dead Man Writing: A note found in SCP-557 says (in part) "I will write in Greek, so that any learned man who finds this place will understand. I am the last of the Keepers, and I will be dead soon."
  • Fling a Light into the Future: The last Keeper leaves a final note in Greek warning of the dangers within the site.
  • Sealed Evil in a Can: Around 2,400 B.C. a tomb was built to be a prison for supernatural beings. Sometime later the "bastard son of Apep" (SCP-557-1) was captured with the help of the gods and secured in the tomb by being chained to a block of granite. Around 300 A.D. the last Keeper (guard) of the tomb died. In 1988 a geological survey team stumbled across the site and somehow released SCP-557-1 from confinement.

SCP-558 - Strange Contact Lenses

  • Fictional Color: When the red contact lenses are worn and used to view infrared light, the wearer sees it as a distinctly new color that they lack the language to describe properly.
  • Go Mad from the Revelation: The black contact lenses usually cause loss of conciousness, begging for the lenses to be removed, self-harm, and incoherent sobbing. One subject who wore them stated that he could see time as a web, and he could see the edges, and pray to god you never see them too.

SCP-562 - Revel Rousers

  • The Fair Folk: It's rather strongly implied that this is a modern version of the Fair Folk bringing people to a party in Faerie, including the Year Inside, Hour Outside effect on its victims and the way they are lured into agreeing to go to it.
  • Year Inside, Hour Outside: After a person is lured through a door and enters the Revel, they appear several years later dead of old age. It's implied that time passes much faster in the area where the Revel is taking place.

SCP-572 - Katana of Apparent Invincibility

  • Dope Slap: Once the Katana is removed from the victim's grasp, "all psychological effects can usually be expunged by a single swift blow to the back of the subject's head".
  • Katanas Are Just Better: Subverted. The wielder thinks this, but it is actually rather dull and ineffectual as a weapon. It's not even a real katana, just a cheaply made novelty sword for display (the model they took the picture from costs forty dollars).
  • Implausible Fencing Powers: Subverted again. The wielder thinks they have these, but they're no better than they are normally and it leads to the person to getting themselves seriously injured or worse trying to show them off.
  • Too Dumb to Live: Basically the Katana's primary effect. See above.

SCP-579 - [DATA EXPUNGED]

  • Nothing Is Scarier: SCP-579 is a major threat contained in an independent site located inside SCP-004 (itself a Mind Screw extravaganza). If initial containment failed, the site will be completely sealed. If that fails, SCP-004 will be destroyed. If that fails, then no further action will be necessary. The entire description of SCP-579 and what makes it such a massive danger is entirely in the audiences' minds.
  • Tailor-Made Prison: A unit made of [DATA EXPUNGED] where the thing is kept floating through electromagnets. It's also full of sensors to warn of any changes.
  • Things Man Was Not Meant to Know: Some hints in whatever text is left, such as the "termination of agents to prevent data leakage" or the mention of its existence apparently being a containment breach, indicate that it's some kind of infohazard. A tale shows the personnel in charge take so many amnestics they become simple-minded if not stupid.
  • Ultimate Evil: SCP-579's description is completely expunged. All information that could be gathered are simply implications.
  • You Can't Go Home Again: Attempts to return 579 to Where It All Began only destroyed the point of origin.
  • You Do NOT Want to Know: Whatever it is, it's so bad that any and all description of it has been expunged.

SCP-582 - A Bundle of Stories

  • Defictionalization: In-Universe. Any story written about him will come true. Presumably including the article for the SCP itself.
  • Retcon: Earlier versions of the article made Bundle extremely similar to the Slender Man. Later versions distanced the description away from the resemblances. For example, the first version had its origins being an early-2000s internet phenomena, and the current version has its origins being the creation of an obscure American 1940-50s Lovecraftian author.
  • Shout-Out: If the addenda weren't there to clarify its origin and the various forms the entity takes, you'd be forgiven for thinking Bundle is just the Slender Man.

SCP-586 - Inscribable Object

  • Malaproper: Attempting to describe the SCP through text makes its whiter unwittingly use these in there sentences.
  • Never My Fault: Apparently, "my orifice is too close to 586" is a common excuse among the employees at the site it's starred in when someone turns in a report without proofreading it first. This doesn't really fly since it's been established that 586 only artifacts you when you're strictly referring to itself, but that doesn't stop some of them from trying anyway.
  • Painting the Medium: The SCP is a green pipe, and its affect causes its article to have many spelling eras. This section has also been effected by this.
  • You Make Me Sic: Writhing or typing anything about the SCP results in one ore more spelling errors.
  • Visual Pun: The SCP's rage image is that of a "Green Pope".

SCP-589 - The Price of Obsession

  • Emotion Eater: There is some speculation among Foundation personnel that this SCP feeds off of the intense anguish it causes its obsessed victims after it leaves them.
  • Hate Plague: Once it and any duplicates vanish from an area, the people exposed to it begin to go insane and start killing each other in massive riots.

SCP-590 - He Feels Your Pain

SCP-592 - Inaccurate History Book

  • Deadly Book: It's a history book that is capable of inflicting injuries on the reader if they read past a certain point (known as the point of divergence), and said injuries may be from wars that never actually happened. In addition, it can cause the reader to become suicidal and suffer other mental issues if they read a passage that is over 10 years past the PoD.

SCP-593 - Contagious Innumeracy

  • Kill It with Fire: SCP-593's containment procedures recommend incineration of all materials that anyone infected with it may have touched.
  • Weakened by the Light: SCP-593 is a genetically-engineered disease similar to measles. After it causes a rash covering the entire body, the victim's eyes become so sensitive that they can be totally blinded by exposure to light.

SCP-597 - The Mother of Them All

  • Blob Monster: It's described as a blob of flesh.
  • Fan Disservice: To disgusting extremes. For one, it compels people (regardless of gender) to want to have sex with it, drink from its teats, and eventually mentally turns them into sex-crazed baby-like toothless Man Children that see it as their "mother". It has a similar effect on animals too.

    600-699 
SCP-600 - "That Guy"
  • The Blank: When seen on surveillance cameras. When seen directly, however, he mimics the individual in front of him.
  • Master of Illusion: He uses illusions to alter his appearance to look just like anyone in front of him.
  • Motor Mouth: Oh boy, does he love to talk!
  • Nice Guy: Subverted; he's generally amicable, but he acts so friendly and creepily personal to people he has never even met (while looking very similar to them, no less) that people become very uncomfortable around him (or at least annoyed).
  • Telepathy: The illusions that SCP-600 creates are sent telepathically into the minds of the people observing it. It can also read the memories of anyone talking to it and use the information while communicating with them.
  • Third-Person Person: An odd example; some of the things he says imply that he doesn't even know that he is SCP-600.

SCP-607 - Dorian the Grey Cat

  • Cats Are Mean: Maybe, maybe not. It's hard to tell. Taking a picture of it using 978 depicted it as being dead, and with everyone near it at the time having been mauled to death, so it's probably not very nice. Then again, this could be due to the Nice Job Breaking It, Hero! involved in their tests on it, or that they were currently cleaning its ears.
  • Death Is Cheap: After being killed, it reanimates later on. It goes on to bond with someone else and tries to kill itself again.
  • Death Seeker: It's always trying to kill itself, whether it's "bonded" to someone or not.
  • Nice Job Breaking It, Hero!: Though it's not proven, the Foundation speculates that the cat's suicidal tendencies just may be due to their extensive testing on it (which involved breaking its legs and shooting it). If that is the case, that would mean they turned an already dangerous SCP downright vicious. Wouldn't be the first time, too. On the other hand, it did cause the death of one agent it had bonded with by starving itself before the Foundation was even aware that there was anything unusual about it, so it may well have been like that already.
  • Resurrective Immortality: After being killed, it reanimates later on. It goes on to bond with someone else and tries to kill itself again.
  • Synchronization: When SCP-607 bonds with someone, anything that happens to it (physical or emotional) will also happen to that person. It also happens to be suicidal, which means anyone it bonds with will not last much longer.
  • Who Wants to Live Forever?: Considering that it's not clear how old it is, this could be another possible explanation for its behavior.

SCP-608 - Fractal Tinsel

  • Disintegrator Ray: SCP-608 will slowly disintegrate anything it touches.
  • Sharpened to a Single Atom: SCP-608 is a fractal with infinitely and progressively smaller branches radiating from it. Branches of monofilament size and smaller can slice through other substances at a molecular or even atomic level.

SCP-610 - The Flesh that Hates

  • Attack of the 50-Foot Whatever: A few of the research teams encounter an absolutely gigantic specimen. Said specimen is responsible for most of their deaths, and is seemingly invulnerable.
  • Baleful Polymorph: Not only does it turn people into instances of itself with varying mutations, but it can also turn other living creatures and even inanimate objects into instances. They also exhibit some strange uses with their powers such as one instance seemingly tear off some of its tendrils and use them as food.
  • Body Horror: The infected suffer horrifying transformations. There's a picture of it too.
  • Combat Tentacles: "SCP-610-L5 - Manned exploration of the Site A tunnels". While the assault team is escaping from the underground church a tendril emerges from the ground, grabs one of them and flings them away. The tendril came from a SCP-610 infected creature hiding under the ground.
  • Expy
    • A virus that horribly mutates infectees. Sound familiar? Just that it lacks the disguising ability that would normally cause paranoia. They also seem to be similar to Necromorphs and the Flood in appearance and variations in mutations. The church-like structure the final exploration team found helps.
    • With the Adytum mythos, the resemblance to the Flood strengthens in some ways; 610 is just a part of a much nastier and widespread whole, with a brilliant, manipulative, well-read, and eternally patient mind at the head ala Gravemind.
  • External Retcon: Another author wrote SCP-610 into the mythos (and modern-day schemes) of Adytum and the Grand Karcist Ion's Sarkic cults, a worldwide Lovecraftian religion of fleshcrafting sorcerers. It is also confirmed that both 610 and Adytum's cults are the FLESH that the Church of the Broken God despises. The loathing is mutual.
  • Hidden Elf Village: More like a Hidden Abomination Village. Site B is an entire ancient, hidden village completely inhabited by SCP-610 instances, and is where the Foundation discovers signs of the Religion of Evil.
  • Hive Mind:
    • Somewhat. While the different instances for the most part seem to carry some sort of link with each other, such as them shrieking when an orb-like structure they created was destroyed, even though some of the infected were in a different part of town, they also seem to exhibit individual behaviors such as one instance randomly beating up another instance.
    • Retcons have made the 610 infestation in Baikal one contingent of a global (and extradimensional) whole: The Sarkic cults of Adytum.
  • Human Resources: Every structure, weapon, and tool the contagion uses is made from flesh and/or bone taken from a victim.
  • Kill It with Fire: This is how specimens and infected subjects are terminated. Also seems to be at least partially why it hasn't spread outside of its point of origin, located in Siberia.
  • Our Zombies Are Different: Plague Zombie with the Body Horror value turned up to eleven, with some heavy Religion of Evil elements added on top.
  • Religion of Evil: The final exploration team discovers a church-like structure underground where the surrounding instances seem to be exhibiting strange, trance-like behaviors, and then another outside, complete with a village. The latter of these plays host to a cannibalistic ritual (seemingly led by a "priest" in a hooded cloak), and features a metal Ouroboros symbol. See External Retcon above for how this religion was expanded on.
  • Time Abyss: The aforementioned churches and other structures are centuries, if not millennia old. Since the contagion has been alive and active for centuries, thousands will have died or worse to make up their tunnel network.
  • The Virus: SCP-610 is a skin disease that spreads via body contact. A very horrible skin disease.
  • Viral Transformation: SCP-610 infected will undergo some rather... unpleasant transformation after the disease spreads to the whole body.
  • You Will Be Assimilated: SCP-610 infected are openly aggressive and actively attempt to spread the disease to non-infected.

SCP-612 - Aggressive Cable

  • Face Full of Alien Wing-Wong: If a human being removes an instance of SCP-612 from a power source the SCP-612 may stick copper wires in their throat and electrocute them. After death occurs the human's spinal cord rips out of their body and becomes a new instance of SCP-612.
  • Salt Solution: A solution of aqueous sodium chloride (AKA salt water) stuns SCP-612 and renders it temporarily inert.
  • Shock and Awe: While plugged into an electricity source SCP-612 can shock any creature it touches and even fire an arc of electricity at targets.

SCP-615 - Stick Blob

  • Kill It with Fire: SCP-615 is extremely flammable. The best way to destroy it is to burn it.
  • Logical Weakness: SCP-615 is made of a large amount of dead and discarded plant matter, such as leaves and branches. It can use its tremendous strength and bulk to engulf, crush and suffocate living victims. However, its wooden mass makes it very vulnerable to fire attacks.

SCP-616 - The Vessel and the Gate

  • Centipede's Dilemma: The reason a clearance level is needed to know that SCP-616-1 is only prevented from closing if the people trying to close it believe they can - people aware of it are far worse at keeping SCP-616-1 open than people who aren't.
  • Clap Your Hands If You Believe: Every time SCP-616-1 opens on its own, seven archbishops of Abrahamic faith need to pray towards it for the full duration of a flight to stop it from closing. The very bottom of the page reveals that keeping SCP-616-1 from closing has nothing to do with religion, but simply requires that people believe they have the power to stop it from closing; how they find that belief is irrelevant.
  • Fictional Colour: In Interview A the survivor says that when the door opened, there was light coming from outside that was a haze of "... colors, but they weren't colors...".
  • Go Mad from the Revelation: Viewing footage of the other side of the portal causes people to go violently insane, though viewing footage of something playing the footage doesn't.
  • Hellgate: It's a portal to Hell. Originally, it was the portal the Dante used to get to Hell, though that was later removed to better fit the site's tone. One proposed rewrite eventually became SCP-1844.
  • Number of the Beast: 616 is one of the alternate numbers of the beast.
  • Portal Door: Once every month the center-left emergency door of a jetliner opens and becomes a portal to Hell, allowing demonic creatures to enter the Foundation's universe.
  • When the Clock Strikes Twelve: Interview A says that the horrifying flight of SCP-616 that brought it to the Foundation's attention occurred at midnight.

SCP-621 - Hypnobulbs

  • Glowing Flora: SCP-621 are an anomalous variant of several types of plants, including tulips (particularly Didier's tulips), roses and lettuce. They are naturally bioluminescent in a variety of colors, but most often purple, blue, or green. The glow has a hypnotizing effect on human beings and many types of animals that causes them to protect the plant.

SCP-625 - Anklebiters

  • Body of Bodies: Each SCP-625 is a rat-like creature that is apparently made up of parts of at least seven different species of rodents seamlessly merged together.
  • Weakened by the Light: When exposed to bright light, SCP-625 will fall unconscious and become dormant. 80 seconds after the light is removed they revive again.

SCP-628 - Flute Copse

  • Brown Note: A grove of hollow sycamore trees with their tops broken off, they can play music like an organ when the wind blows. Their music includes infrasound (AKA subsonics) that can cause disorientation and the emotions of fear, awe, sorrow and anxiety in those listening to it.
  • Healing Factor: When cut, the trees heal at a tremendously accelerated rate. A tree cut completely through can heal within a day.
  • Weather Manipulation: The trees that make up SCP-628 have the ability to increase local wind speed from 9 km/hr to 77 km/hr in less than 80 seconds as well as altering cloud cover.

SCP-630 - Black Glacier

  • Kill It with Fire: The strange ice known as SCP-630 can stand temperatures up to 1500 °C. The best way to destroy it is to burn it with a mixture of aluminum and sodium hydroxide.
  • The Virus: Touching the strange ice causes the victim to slowly transform into more of the ice.

SCP-631 - Nyctophobic Nocturnal Predator

  • Bizarre Alien Reproduction: SCP-631 eats the internal organs of a sleeping human victim and lays its eggs in the body. When the eggs hatch the babies eat the body.
  • Spawn Broodling: SCP-631 injects a paralyzing poison into a person with its stinger, eats their internal organs and lays its eggs in the resulting body cavities. When the eggs hatch an hour later, the babies eat the rest of the body.
  • Weakened by the Light: Inverted. SCP-631 becomes invisible to normal sight in daylight, which makes it much more difficult to see and attack them.

SCP-632 - Intrusive Arachnid Thoughts

  • Bizarre Alien Reproduction: SCP-632 reproduces by exposing humans to its sensory triggers, including seeing the patterns on its abdomen and feeling it crawling on the skin. It will then cause intrusive thoughts of spiders and grow filaments of baby spiders to inside the brain, causing a bad headache. The victim's attempts to stop the headache releases the adult SCP-632.
  • Chest Burster: After the baby SCP-632 inside the victim's brain have grown large enough, the victim will repeatedly hit their forehead with great force to relieve the pain. When the victim's forehead shatters, the baby SCP-632 will leave the skull through the hole.
  • Eye Scream: If the victim of an SCP-632 infestation is too weak to fracture their own forehead and allow the baby SCP-632 to escape, they will eat the victim's eyes and escape through the eye sockets.
  • Spawn Broodling: SCP-632 are spiders that reproduce inside human victims. The baby spiders grow inside the victim's brain and cause a terrible headache. When the victim damages their skull to stop the headache the spiders adult SCP-632 are released.

SCP-633 - Ghost In The Machine

  • Contagious A.I.: When the SCP-633 program was captured and taken to a Foundation site, it tricked the technicians into letting it infiltrate the local computer system and take control of it, leading to system failure and a containment breach.
  • Instant A.I.: Just Add Water!: The SCP-633 program was originally designed by terrorists to attack U.S. government computers. However, it was given the ability to re-write its own code as needed, which eventually allowed it to become sapient.

SCP-638 - The Roaring One

  • Chick Magnet: It exhibits a powerful influence over women in a 20-metre radius, and once they are in its presence, they lose all inhibitions. Attempting to remove them will result in violence.
  • Facial Horror: In the page's picture, its face looks extremely scarred.
  • Healing Factor: SCP-638 heals at an abnormally high rate proportional to its consumption of raw meat and wine.
  • Make Me Wanna Shout: When SCP-638 is enraged, it can shout with tremendous volume and force, and its effects include deafening personnel and blowing steel doors off their hinges.
  • Super Strength: When SCP-633 is extremely angry, it can dent steel with its blows.

SCP-643 - Delicious Chocolates

  • Animate Inanimate Object: If SCP-643 ever becomes liquid, it will become animate and try to cover any nearby edible substance with itself.
  • Supernaturally Delicious and Nutritious: Instances of SCP-643-1 (organisms that have eaten SCP-643 or food covered in it) will become targets of other organisms, as they will attempt to eat them regardless of their prior relationship.

SCP-647 - Hungry Box

  • Cardboard Box Home: Invoked by SCP-647 in order to lure its prey.
  • Disposable Vagrant: SCP-647 is a cardboard box that prefers urban environments. It can expand itself to be large enough for anyone to enter it, and shows a preference for people of disheveled appearance. It makes itself desirable to homeless people by appearing to have blankets, food, and liquor inside of it. Once someone enters it traps them and digests them.
  • Super Spit: If SCP-647 is blocked from relocating, it will spray its digestive juices over whatever is blocking it, causing the blockage to dissolve in 15-20 minutes.

SCP-648 - The Labyrinth

  • Alien Geometries: The maze-like interior of SCP-648 changes on an unpredictable basis, often cutting off personnel inside it from the exit. Over 14 square kilometers of SCP-648 has been explored without reaching any exit or edge.
  • Bigger on the Inside: The extradimensional maze SCP-648 is larger than the real world maze that contains it.

SCP-654 - Thunderhorn

  • Mutants: SCP-654's ability to fire a lightning bolt from its horn is noted as being a mutation.
  • Shock and Awe: SCP-654 is a narwhal that can fire lightning bolts from its horn. It uses them to kill seals so it can eat them.

SCP-661 - Salesman, Too Good To Be True

  • Butt-Monkey: The Foundation (or at least the guys overseeing him) really likes to pick on him.
  • Comedic Sociopathy: Yes, SCP-661 is a jerk, but that doesn't excuse the researchers constantly denying him simple things just because they think it's funny.
    Requests not processed by Dr. ██████
    -One (1) Leather Jacket (Denied. Subject placed into Restraint Jacket instead.)
    -"Tacos". (Denied. Subject given burrito instead.)
    -One (1) CD of "The Best of Led Zeppelin" (Denied. Subject given a CD of The Monkees.)
    -"████. It ███████ reeks in here. Open a god████ window or something". (Denied. Officer ██████ passed flatulence in cell instead.)
    "A spot of sun". (Denied. Officer ██████ shined a flashlight in his face for 10 minutes.)
    One (1) Baconator cheeseburger from Wendy's (Denied. Subject was given one (1) Boca brand soy burger instead.)
    One (1) pair of Aviator-brand Sunglasses (Denied. Lights turned off in room.)
    One (1) 'Pepsi' brand soft drink (Denied. Given one (1) can of 'Coca-Cola' brand soft drink as a suitable replacement. After recovering from concussion, Dr. █████ was reassigned to a non-sentient SCP.)
    Gentlemen, seriously. As abrasive and rude as SCP-661 is, he is still a sentient SCP and should be afforded some level of respect. I don't care what he does, events like the above will not be tolerated.
    Dr. ███████
  • Compelling Voice: He has this ability. Although it's less telling them to do something and more making them want to do something.
  • Honest John's Dealership: He was an advertising/marketing agent prior to containment.
  • Jerkass: He's described as abrasive and demanding.
  • Logical Weakness:
    • One of the tests revealed that his power only works on people who can understand his words.
    • A lesser one is that people can ignore his suggestions if something more important to them is at stake. For example, when a subject was instructed to attack 661 and threatened with death if he did not, he was able to ignore 661. At least, until 661 convinced the subject that he did want to die.
  • Must Have Nicotine: He likes the Smoking Is Cool image, and it swiftly became apparent to his guards that he's a habitual smoker.
  • Pet the Dog: His requests go from internet access and expensive imported cigars (denied for security reasons) to a TV with cable and some cigarettes (denied because the guards enjoy teasing him). When the researchers noticed the guards were denying him basic necessities he was finally given some nicotine addiction medicine and a CD player and some books (even if he can barely read).
  • Poke the Poodle: Usually on the receiving end of this.

SCP-662 - Butler's Hand Bell

  • Battle Butler: Well, Deeds is a butler... and you can send him to kill people.
  • Benevolent Genie: Deeds will always try to fulfill his master's wishes as intended, and if he is incapable of doing so, will politely say so and suggest an alternative.
  • Genie in a Bottle: Deeds, with the bell serving as his bottle.
  • Mundane Utility:
    • A number of "experiments" done with this SCP amount to Dr. Mirth getting Deeds to do his own personal errands. The Council had to tell him to knock it off.
    • How the bell itself was found also qualifies. It came to the Foundation's attention when a petty thief was trying to sell it to a pawn shop.
  • My Master, Right or Wrong: His loyalties to whoever holds the bell doesn't seem to make a difference to him, even if that person purposely got him killed last time he did what they asked.
  • Offscreen Teleportation: He needs to be unobserved to bring back items, and knows if he is being observed. If there are cameras, they simply malfunction for a minute or two, with Deeds not knowing or caring how he got the item.
  • Unexplained Recovery: Whenever Deeds is killed, no matter how severe his injuries, he comes right back once his corpse is out of sight and the bell is rung.
  • A Wizard Did It: Not even Deeds himself is quite sure how he's able to do what he does. Thinking about it too much seems to distress him.

SCP-674 - The Exposition Gun

  • Breaking the Fourth Wall: When SCP-674 is fired at characters in a TV show or movie, the user perceives that the characters respond to the shooting and even talk to the user.
  • The Fourth Wall Will Not Protect You: As a side effect of its fourth wall-breaking properties, prolonged use allows the characters in the show to retaliate, as the unfortunate doctor found out when Spock returned fire with a phaser.
  • Imperial Stormtrooper Marksmanship Academy: Shooting into a show results in things being followed in accordance with the logic of the show you're firing into. Thus, when a researcher opened fire on an episode of Star Trek he was never able to fatally wound Kirk; every shot either went into his shoulder or a nearby Redshirt.
  • Reverse Polarity: When a Foundation doctor tested SCP-674 by firing it at a TV show or movie featuring the cast of Star Trek: The Original Series, Spock reversed the polarity of a phaser and shot him with it, killing him.

SCP-679 - Eyerot

SCP-682 - Hard-to-Destroy Reptile

  • Absolute Xenophobe: Toward nearly all Earth life.
  • Adaptive Ability:
    • Fortunately, the adaptations wear off eventually and it can always be at least incapacitated by heavy physical damage.
    • Unfortunately, 682's adaptive ability is so extremely powerful it basically made him Nigh Invulnerable. He survives after being disintegrated into a small bundle of particles.
    • You know 173 right up there? They put 173 in 682's chamber and shot 682's eyes. 682 then proceeded to grow more eyes.
  • Berserk Button: Earth life, with rare exceptions.
  • Big Eater: At one point, it ate several "682 specials" during a termination attempt and only suffered a forty-five-minute heart attack after eating the first one.
  • Boastful Rap: Its communication with SCP-1548. Which was in Morse code.
  • Breakout Character: Right up there with SCP-173 as the SCP.
  • Break the Badass: Not this version, but there is an alternate universe where it ends up with the SPC, the Shark Punching Center. It was offered freedom in exchange for it punching sharks. It's refusal led it to being labeled SPC-682 "Very Punchable Shark" and basically become a punching bag. They actually broke the thing's spirit and it agreed to punch sharks, but by that point, they have deemed too valuable to be let go.
  • The Cat Came Back: If there's an attempt to remove 682 instead of killing it, it will come back (whether by exchanging genie - 702 - or teleporter - 507).
  • Call a Smeerp a "Rabbit": It only looks like a reptile.
  • Cluster F-Bomb: He's capable of human speech, although much of it is quite angry and profane.
  • Creepy Monotone: In the audio version of its interview, it speaks in a scary, almost robotic sounding voice.
  • Cruel Mercy: In a timeline where humanity was wiped out by SCP-3519, 682 saves Sole Survivor O5-6 from SCP-2490, giving him a cutting piece of snark as he leaves:
    SCP-682: We are alike now, meat. Killing you would only end suffering.
  • Death Seeker: Possibly. When 2599 was in the process of killing SCP-682, SCP-682 said "KILL ME, YOU SACK OF ORGANS, DO IT". However, it's also plausible that it was just trying to confuse her.
  • Eldritch Abomination
    • When brought in to terminate 682, SCP-343—who is thought to be God—refused, remarking, "He's not one of mine. Deal with him yourself." Hoo boy. Made all the more explicit by the fact that the two can neither see nor interact with each other.
    • Made explicit after several tests with other SCPs which cast doubts on whether SCP-682 is either alive or dead. One of the scientists commented that this is the point where people start getting offered as sacrifices.
    • Interestingly, 682 seems to see humanity as a bunch of abominations, hence why it's always trying to destroy everything.
  • Evil Counterpart: To SCP-1364: 682 is an unidentifiable "reptile" that adapts to survive and hates everything while 1364 is an anteater that, despite being harmed by bright lights, still wants a hug.
  • Evil Sounds Deep: In an alternate version of its interview.
  • Exactly What It Says on the Tin: SCP-682 really is a Hard-To-Destroy Reptile. Although the picture used in the article is of "The Moscow Monster", which was really just the corpse of a beluga whale.
  • Expy: Adaptive Ability, Healing Factor, extremely difficult to kill, and tries to kill everything around it? SCP-682 is basically a more reptilian version of Doomsday.
  • Extreme Omnivore: It gains energy from anything it ingests, even the acid used to contain it.
  • Failure Is the Only Option: Any attempts to kill SCP-682 are met with failure and will always end in failure. Doing otherwise would defeat the point of SCP-682. There is in fact one proven way to definitely and permanently kill 682, and that is to use SCP-2935. Unfortunately, doing so would also kill all life on the planet Earth, and possibly in the rest of the universe as well.
  • Flanderization: Many off-site fanfics about 682 made it look like that Power Copying was one of 682's main abilities. It was actually used exactly once in its test log, and was more like turning an anomaly's effects on others and away from itself. 682 never "learned" it.
  • From a Single Cell: One termination log mentioned that 682 came back from only 0.03 milliliters of its blood remaining.
  • Generic Doomsday Villain: In a way, SCP-682 is purely a vehicle for SCP cross-test fun. Detractors of the article sees 682 as lacking any sort of personality beyond "they are disgusting", and is created purely so that people can propose SCP cross-tests to try to destroy it.
  • Godzilla Threshold: "Special Containment Procedures: SCP-682 must be destroyed as soon as possible." While the Foundation is usually focused on containing and studying SCP's rather than destroying them, 682 is one of the few they've determined to be so dangerous that it must be killed.
  • Good Thing You Can Heal: Good for 682, bad for everyone else. The Foundation had thrown all kinds of different things on 682. None worked and 682 regenerated all its wounds.
  • Half the Man He Used to Be: They cut it in half with a high-powered laser. Each half grew back into a full-size 682. Thankfully, once 682-B was incapacitated and 682-A was cornered, 682-A ate 682-B in an attempt to invoke Heal Thyself.
  • Hates Everyone Equally: Its nothing personal, but you and your individuality are the abomination as far as The Hard To Destroy Lizard is concerned and you must be dealt with accordingly.
  • Healing Factor: One of its most notable abilities; it can recover from any harm inflicted on it.
  • Humans Through Alien Eyes: One possible explanation for why it always tries to kill everything except SCP-053. It's not evil, it's just that everything alive in our world except SCP-053 is so horribly, gut-wrenchingly disgusting and wrong that SCP-682 can't help reacting by trying to make us all stop existing ASAP. It also didn't try to kill Dr. Clef, most likely because Clef's "face cycling" ability made 682 perceive him as something else.
    "The Leak": "Whatever Clef had done that causes his head to be unrecordable seems to bugger up more than just cameras. 682 was unsure as to what in the fuck was going on. 682 isn't inherently a violent organism, as we understand the term. When not faced with unreal terror, 682 is actually somewhat cautious and shy, like many big predators. If Clef had stayed inside, 682 would have probably adapted past the “face cycling” thing, and butcher[ed] him. As it was, the big gecko was waiting to see what would happen."
  • Infernal Retaliation: The Foundation once attempted to launch SCP-682 into the sun with a very large cannon. It came back on fire. Of course, this was only mentioned in the joke SCP entry for said very large cannon, so it's not canon by virtue of the 1543-J not existing within SCP canon (nebulous and ill-defined as it is). Just cannon. It also had wings that launched razor-sharp feathers.
  • Iron Butt Monkey: The attempts made by the Foundation to kill 682 are almost too numerous to list. However, 682's ability to adapt and recover mean that it's not fazed by any of them, and often retaliates in kind.
  • It Can Think: Its the single aspect of the Hard to Destroy Reptile that the Foundation hates and fears most. 682 is very very intelligent and wants to destroy us all. It didn't take long for O5 personnel to catch on, and issue orders to have this monster not studied, but terminated as soon as possible.
  • The Juggernaut: SCP-682 is unstoppable. It has breached containment six times, and resulted in the deaths of dozens of Foundation personnel.
  • Just Eat Him: Its preferred method of disposing with us, since dead humans are just as equally offensive to it as the living.
  • Killer Rabbit: There was an attempt to retcon it into a harmless regular cat through Reality Warping. It didn't prove to be any less dangerous.
  • Nigh Invulnerable: This is its main trait, due to its Adaptive Ability and Healing Factor. Even to the most consistently fatal SCPs, SCP-682 can take them on and survive, especially after the 1st contact.
  • Non-Malicious Monster: In a strange way, 682 is shy and somewhat nervous of anything new it encounters. Unless that something new should be a human being.
  • Not Zilla: What the Foundation is desperate to prevent, hence why its constantly stuck in an acid bath that damages it as much as it regenerates and grows from continued exposure.
  • Nuke 'em:
    • One of the proposed ways to end it was by using a 60 MT thermonuclear bomb. Ultimately decided against, because
    O5-█: Yes, it's a goddamn nuke, but if 682 survives and adapts we'd be boned beyond belief.
  • Obliviously Evil: While he is a grouch and a bit of a jerk, the way he talks implies that he thinks he's doing the world a favor by killing all those "disgusting humans".
  • Offscreen Moment of Awesome: During its fifth containment breach, the Sole Survivor who captured it is Personnel D-221. Yes, a D-class. And no, there's no detail how he did it.
  • Omnicidal Maniac: SCP-682 doesn't want to set the world on fire, but does want to destroy every living thing on it except for SCP-053, which is close enough. Dr. Clef also doesn't seem to trigger its murder-death-kill reflex, most likely because of whatever Clef did to make his face unrecordable.
  • Pet the Dog: SCP-053 is so far the only living thing that 682 didn't immediately try to kill—in fact, 053 played with it. Did we mention that this is the opposite of what usually happens, given that 053's main power seems to be to make people inexplicably and violently hate her? Went into Papa Wolf and Even Evil Has Loved Ones territory when 682 attacked the personnel sent to retrieve 053, presumably believing they'd harm 053. Then again, it may have just been doing what it usually does, mauling anything in sight.
  • Reality Warper: Sort of; it's not so much that 682 can warp reality, but more like the laws of reality just don't apply to it.
  • Reptiles Are Abhorrent: While it's not any real animal, it vaguely resembles a reptilian, and is referred to as "hard-to-destroy-reptile".
  • Sophisticated as Hell: It calls SCP-999 a "feculent little snot wad" and invites it to "[DATA EXPUNGED] and die", and generally gets pretty vicious verbally if it's restrained physically.
  • Trapped in Another World: Implied to not be from our reality as Our laws of reality don't seem to fully apply to it, and it can't be detected by SCP-343.
  • The Undead: Heavily implied to not be biologically "living" in the traditional sense and possibly one of these.
  • Unstoppable Rage:
    • It's not as popular as its other traits, but SCP-682 has episodes that are hard to describe as anything else, where it seems to lose control and become even more aggressive and even harder to incapacitate than usual.
    • After being exposed to SCP-999, it went into an utterly insane state, unleashing a wave that caused everyone in range to enter crippling fits of laughter and proceeded to go on a rampage, all the while laughing maniacally.
  • Violence Is the Only Option: It can't be safely contained, so the Foundation deems its destruction necessary.
  • Why Did It Have to Be Snakes?:
    • SCP-173 is one of very few things that SCP-682 is completely terrified of.
    • There's also SCP-524, the omnivorous (as in will eat everything, including itself) rabbit. When put together, 524 started chewing on 682's leg, and chased 682 around the testing chamber for two minutes before 682 ran four meters up the wall and out of 524's reach.
  • Woobie, Destroyer of Worlds: It seems to find humans so wrong it can't help but kill them. That they are trapping, torturing, and trying to kill it isn't helping.
  • The Worf Effect:
    • They found its dead body in SCP-2935, because absolutely EVERYTHING is dead on that side of the portal.
    • Played for laugh in SCP-666½-J. The diarrhea it causes drive 682 to suicide: it threw its arms in the air, yelled "Yog Sothoth take me now!" and died.
  • Would Hurt a Child:
    • Except for SCP-053.
    • Another notable example is found in the Attempted Termination Logs, in which one researcher got the bright idea to start tossing completely normal children to 682, apparently out of some misplaced hope of recreating the incident with 053. Said researcher was quickly determined to be a sadistic asshole and thus was promptly tossed to 682 himself.
  • You Are Who You Eat: Not only are its adaptive capabilities incredible, but it has the ability to absorb whoever it devours.

SCP-692 - Revives the Colours

  • Kill It with Fire: When clothing is animated by exposure to SCP-692, security personnel are armed with flamethrowers so they can incinerate it if it goes out of control.
  • Logical Weakness: Clothing animated by SCP-692 is resistant to most forms of physical injury (such as blows, bullets and so on) because, like normal clothing, it isn't alive. However, like normal clothing it is vulnerable to fire.

SCP-695 - Eels

  • Bizarre Alien Reproduction: Juvenile SCP-695 perform a Orifice Invasion on a male human, grow to adult size and lay eggs. They then force the host to rape a female human and infect her with the eggs. The eggs will grow into juveniles, which will leave the female's body through either an Orifice Evacuation or performing a Chest Burster out of her abdomen.
  • Chest Burster: After SCP-695 eggs have grown to juvenile size inside a female human host, they may escape by erupting through the wall of her abdomen.
  • Face Full of Alien Wing-Wong: SCP-695 reproduce by entering a male human and laying eggs, then forcing the male to rape a woman and infect her with the eggs.
  • Orifice Evacuation: After SCP-695 eggs have grown to juvenile size inside a female human host, they may escape by exiting through her vagina, anus or mouth.
  • Orifice Invasion: SCP-695's life cycle starts when its juvenile form enters a human male through his mouth, nose, anus, and urethra.

SCP-687 - NOIR

SCP-699 - Mystery Box

  • Conveniently Interrupted Document: A rare example of the accidental version of this trope. A report was attached to SCP-699 when it arrived at the Foundation. Parts of the report were too damaged to be read and were replaced with [report damaged].
  • Telepathy: The Foundation has concluded that the contents of SCP-699 are telepathic because it can influence the minds of observers and have them see the contents of the box differently. Some see the contents as Your Heart's Desire, some see it as something dangerous, and two Doctors can see nothing at all in it.
  • Your Heart's Desire: 90% of people who look at SCP-699 see that it holds "something they want to possess or to release...", such as '''... precious metals, artwork, family members, pets, religious figures, and apparently useful technology...".

    700-799 
SCP-701 - The Hanged King's Tragedy
  • Brown Note: An unusual version in the form of a 17th century play script that can sporadically cause a Hate Plague to the performers and audience.
  • Culture Police: The Foundation do this deliberately to prevent any more incidents happening, but copies of the play keep popping up on the internet.
  • Curtain Call: Involves the performers killing themselves and the Hanged Man taking centre stage, spreading his madness to the audience.
  • Driven to Suicide: Usually the outcome of the infected performance, with the remaining actors (who haven't already been murdered) killing themselves. In the last recorded incident, they hung themselves from the rafters.
  • Expy: Of The King in Yellow being a fictional tragedy play that causes madness and keeps popping up even though people try to not read it. The Real After All Alagadda also is very similar to the actual domain of Hastur in the Cthulhu Mythos, which was inspired the The King in Yellow, with the "Hanged King" of the play possibly being a stand in for Hastur's avatar The King into Yellow.
  • Hate Plague: Performing the play ultimately leads to this, causing the actors to become violent, murdering each other and committing suicide. This then spreads to the audience when the play ends, who then start attacking each other regardless of prior relationship. Survivors can snap out of it 24 hours later, either with no memory of events or are rendered utterly catatonic by what happened.
  • Human Sacrifice: What the actors do in the final act, murdering one of their own (who plays a king who is hung), then slashing the throat of another, before hanging themselves.
  • Humanoid Abomination: The Hanged King himself is covered completely in bandages and wears what looks like a sack on his head, indicating he may have been hung. He materialises during a performance, often remanining as a Meaningful Background Event until properly incorporated into the play's events, influencing the performers to commit violent acts and then kill themselves.
    • The Hanged King also "wears" high heels, just like the "Ambassador" of the real Alagadda, from SCP-2264, is also a Humanoid Abomination.
  • Irony: 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.
  • Our Acts Are Different: The play has the more classic five act structure, but also incorporates unnoticed ad-libbing, incorporating the Hanged King into the performance, violence, then mass suicide/murder.
  • Real After All: Alagadda is assumed to be a fictional nation by people analyzing the play...but it's real. It's SCP-2264, and the Ambassador is real as well, as is the king.
  • The Secret of Long Pork Pies: One scene in the actual play involves a duke getting killed and his corpse being used as meat in a stew.
  • The Virus: Described as a self-evolving memetic virus that is somehow transmitted through the play. A potential hypothesis behind the cause is expunged.

SCP-706 - Perfect Porcelain Doll

  • Abusive Parents: Her father beat her when he was drunk and she thinks her mother loved her doll collection more than her.
  • Living Toy: She's a girl that somehow became a sentient porcelain doll.
  • Vanity Is Feminine: She is obsessive about maintaining her appearance to the point where she becomes distressed when denied the ability to do so.

SCP-708 - The Big Orange Forklift

  • Artifact Domination: Anyone who sits in SCP-708 and starts it up is subject to its mental effects. If the person has no violent inclinations then they will be obsessed with using SCP-708 to lift other objects. If they have violent tendencies they will use SCP-708 as a weapon against anyone or anything they can see.
  • Emotion Control: When someone looks at SCP-708 for more than 20 seconds they become extremely enthusiastic about it and want to operate it. Anyone restrained from operating it will engage in emotional outbursts like a young child. Anyone who has been looking at SCP-708 or has operated it before feels jealousy at seeing anyone else operating it.
  • Emotion Eater: Some Foundation scientists believe that SCP-708 feeds on its driver's enthusiasm.

SCP-712 - The Impossible Colors

  • Dead Man's Switch: The apparatus has a fail secure system installed in it. If the researcher viewing the Fictional Color is incapacitated and releases pressure on a thumb switch their view of the color will be blocked by a light-absorbing panel.
  • Fictional Colour: SCP-712-a and SCP-712-b are two impossible colors outside the visible spectrum created by a complicated piece of apparatus. Viewing them can cause migraines and/or grand mal seizures.

SCP-716 - The Train

  • Bigger on the Inside: From the outside SCP-716 appears to have a variable number of cars (from 8 to 20) at any given time. Upon being entered it appears to have an unlimited number of cars.
  • Sleepwalking: Anyone who enters REM sleep within 100 meters of a contained SCP-716 will sleepwalk in its direction and enter it.
  • Weather Manipulation: SCP-716 gives off an unknown form of radiation that can (among other effects) alter the nature and severity of local weather patterns.

SCP-719 - Light-Bringer

  • Conveniently Interrupted Document: Another accidental version. A note found during the recovery of the item was partially burned. The remaining sections indicate that SCP-719 is a doorway for an extradimensional being to enter our reality.
  • Light Is Not Good: Said best by the entity itself:
    You will know the light and pray for darkness
  • Louis Cypher: The otherdimensional being using SCP-719 to communicate with humans has a cult that worships him. In their writings the being is referred to as "The Light-Bringer" (c.f. Lucifer, "light bringing") and "The Morning Star".
  • Continuity Nod: According to Word of God and a few clues in the entry, the Light-Bringer is He-Who-Made-Light, brother of He-Who-Made-Dark.

SCP-723 - Aging Staircase

  • Bigger on the Inside: An examination of the exterior of the tower in which SCP-723 is located indicates that SCP-723 extends further up than the exterior architecture should allow.
  • Mind Manipulation: Once a person crosses the 4th/5th step, they are compelled to continue climbing up the staircase until they die.
  • Rapid Aging: SCP-723 is a spiral stone staircase. When a person climbs it, after the fourth or fifth step they start aging rapidly, with additional aging occurring for each additional step taken.

SCP-726 - Reconstructive Maggots

  • Bestiality Is Depraved: Implied in the discovery report:
    On August 16th, 19██ a Mrs. Faber of Beckley, West Virginia, was discovered nude in a dumpster behind a local ██████ ████, engaging in [REDACTED] with a large male [REDACTED] and subsequently hospitalized for acute dementia.
  • Came Back Wrong: The organisms reconstituted by the maggots exhibit blowfly behaviour, whether the original tissue sample was taken from a living organism or one that had been dead for thousands of years.
  • Clone Degeneration: Several tests conducted using a Norwegian rat involve using the maggots to create it again and again, and each time the reconstructed rat develops defects, until eventually a mass of undifferentiated cells, which acts much like a slug, is created.
  • Hot Skitty-on-Wailord Action: Reconstituted organisms will try to mate without regard to their original species, and the female produces SCP-726 eggs if this is successful.
  • Mystery Meat: A can of "potted meat food product" was tested with the maggots, which resulted in [DATA EXPUNGED].
  • Sanity Slippage: If someone has their wound healed by SCP-726 or eats products created from its reconstituted organisms, their behaviour will degenerate over several hours until they act like reconstituted organisms.

SCP-728 - The Forever Room

  • Rapid Aging: Can occur due to the temporal distortion effects on the inside of SCP-728. During one test only one hour passed on the outside of SCP-728, but when SCP-728 was opened again, the person who had been inside SCP-728 had aged to death.
  • Year Inside, Hour Outside:
    • During one test a subject inside SCP-728 experienced two hours of elapsed time while only five minutes passed outside.
    • In another test hundreds of years passed inside SCP-728 while only one hour passed outside of it.
    • In a third test several years passed inside the container while one hour occurred outside it.
  • Year Outside, Hour Inside:
    • During one test, an hour passed on the outside of SCP-728 while only 1 minute thirty seconds elapsed inside it.
    • In another test, 66 hours passed outside the container while no time at all passed inside it.

SCP-734 - The Baby

  • Body Horror: The effects of touching him, which were initially mistaken for an unknown form of flesh-eating bacteria.
  • Creepy Child: Averted. Aside from his anomalous effect, he shows no mental or genetic abnormalities from a regular baby.
  • Death by Childbirth: His mother died, presumably from his effect. No one's sure how she was able to carry him to term.
  • Make Them Rot: Human tissue that makes contact with any of his cells, including his mucus, will gradually decay.

SCP-735 - The Insult Box

SCP-738 - The Devil's Deal

  • A Form You Are Comfortable With: The entity takes a different form for each person who interacts with it, although it is only visible to the person making the deal. Some of the forms it's taken include a man in a red and gold business suit, a beautiful and seductive woman, a law school professor, a large pink rabbit, and a large snake.
  • Affably Evil: As mentioned below, after the incident with the lawyer the entity left a letter thanking the Foundation for the fun it had. And even it was a little depressed by the deal it made with one mentally disabled D-class (trading the D-class's cherished toy for a Sloppy Joe).
  • Ambiguous Syntax: The entity likes to exploit this, so the Foundation set a contract lawyer on him. The lawyer dropped from exhaustion 41 hours in and the entity had a blast.
  • Be Careful What You Wish For: The entity connected to SCP-738 grants wishes as part of a bargain, but it'll only give exactly what its agreed to and no more. For example, one subject who asked for "freedom" disappeared from custody, but was captured again a few hours later.
  • Deal with the Devil: Anyone who interacts with SCP-738 can make a request. The entity connected to SCP-738 will set a price to be paid by the subject, usually involving emotional or physical pain proportional to the value of the request. If the subject agrees, they get their request and the entity extracts the price.
  • Even Evil Has Standards: It will joyously ruin the lives of almost anyone who makes a deal with it, but the entity apparently felt bad when it took a stuffed toy named Mopsy from a mentally disabled D-class in exchange for a Sloppy Joe... not that this stopped it from showing him papers with text insulting the D-class that he couldn't read.
  • Evil Lawyer Joke: They sat a member of their legal team down in the chair. 41 hours and 900 pages of writing later (not counting schedules and exhibits) the Foundation lawyer had passed out from exhaustion before a deal could be finished, and 738 told them it was "the most fun he'd had in years."
  • Exact Words: It stated that the entity will fulfill any agreed-upon wish or request to the letter, but no further. Trying to avert this is why the contract negotiations with the lawyer took so long. Apparently they were trying to agree on a definition of 'shall' when his stamina gave out.
  • Magically Binding Contract: A mentally disabled D-class exchanged his beloved toy, Mopsy, for a Sloppy Joe. An identical replacement toy was given to him, but it disappeared the moment he named it "Mopsy."
  • Intangible Price: Payment may include things such as the death of a best friend or memories of your mother.
  • Worthy Opponent: The entity seems to have found one in the senior counsel of the Foundation's legal team. He passed out from sheer exhaustion and ended the session before any deal was completed after 41 straight hours of negotiation, but the entity seemed to enjoy the challenge.
    "Please come back any time. I haven't had so much fun in years."

SCP-742 - Retrovirus

  • Our Vampires Are Different: SCP-742 is a retrovirus that transforms humans into vampire-like creatures that paralyze their victims with a paralyzing bite and drain bone marrow instead of blood.
  • Vampiric Draining: People infected with SCP-742 will drain the bone marrow from other humans. The stem cells in the marrow allow them to cease aging, and stem cells taken from fetuses allow them to create a SCP-742 filled fluid that they can inject into other humans in order to infect them.

SCP-743 - A Chocolate Fountain

  • Mundane Utility: The Foundation uses it as a means of terminating D-class personnel.
  • Nigh Invulnerable: The Foundation has noted that while it is not invulnerable, it has a high resistance to damage and uses its creatures to defend itself.
  • To Serve Man: It seems to prefer consuming live humans.
  • Zerg Rush: The creatures that emerge from it are individually weak, but they swarm in massive numbers to harvest organic material.

SCP-746 - Pseudo-Avian

  • Badass Grandpa: He is highly acrobatic, can sprint at a speed of 55km, knows several forms of martial arts and has killed multiple field agents before finally being contained.
  • Cultured Badass: He seems to play instruments as he was given some for entertainment.
  • Feathered Fiend: He has feathers, although he's not actually a bird, and he's rather violent.
  • Flight: The articles' image of him sitting on a high tree branch seems to indicate this.
  • Gag Nose: His nose is 28 cm long, which makes him look rather odd.
  • Grumpy Old Man: Not the nicest senior around.
  • I Know Karate: See above.
  • Really 700 Years Old: He claims to be exactly that.
  • Sinister Schnoz: His nose is 28 cm long and he's quite dangerous.
  • Tengu: His description all but explicitly states he is one.

SCP-747 - Children and Dolls

  • And I Must Scream: The people they turn into dolls are still alive afterward.
  • Creepy Child: Six of them. They're also massive woobies.
  • Creepy Doll: They turn people into this.
  • Death by Childbirth: SCP-747-07 was discovered with a crayon drawn short story of a mother and son reuniting in the afterlife. His own mother apparently died giving birth to him before he died at age nine
  • Jacob Marley Apparel: They are all wearing and/or holding something from when they were alive.
  • Our Ghosts Are Different: They have a lot of classic aspects of ghosts; they died and came back to life, they can walk through solid surfaces, they appear to have some memories of their past lives and do not seem to be fully aware of their surroundings. However, they are also "semi-corporeal" and have the anomalous effects mentioned above.
  • Security Blanket: Their "dolls". Also:
    The commonality of the children, according to research, is that they all owned a doll precious to them at their time of death.

SCP-748 - Industrial Dissolution

  • Baleful Polymorph: One of the products created by SCP-748 is cigarettes. When they're lit, anyone inhaling their vapor is turned into a basking shark over a period of 30 minutes.
  • Brain in a Jar: The SCP-748 facility is controlled by the brain of its creator, which is stored in a vat. Nearby are 200 lobotomized human brains contained in glass cylinders filled with a green liquid. They act as auxiliary memory for the controlling brain.
  • Half-Human Hybrid: One of SCP-748's products is the meat of a creature that is a hybrid species of human, squid and pig.

SCP-751 - Organ Eater

  • Chest Burster: After eating its victim's internal organs and increasing in size, SCP-751 swells up and causes the victim's skin to stretch and burst, releasing it from the body.
  • Facefull Of Alien Wing Wong: SCP-751 infiltrates the victim's torso, eats their stomach and takes its place. It then eats and replaces other organs (intestines, liver, kidneys and lungs). Finally, it increases in size and bursts out of the victim's body, afterwards dividing into 10-20 offspring.

SCP-752 - Altruistic Utopia

  • Artificial Human: The "Eudaimoniacs" were built by Alpha to be what they are.
  • Fantastic Caste System: The strongest and least intelligent 752-1 are born for construction and little else. They willingly work themselves to death for the good of the whole. Notably, analysis finds their social structure is more like that of bees or ants than any mammal.
  • Genetic Engineering Is the New Nuke: The Alpha scientists that engineered them made them like humans in many ways, but the ways in which they are different make them repulsive to basic human morality.
  • Gone Horribly Wrong: SCP-752 was built to be a new utopia. While the society is advanced by technological standards, that progress came at the cost of their humanity.
  • Good Feels Good: Horribly deconstructed. SCP 752-1 was built to rationally, willingly be unselfish and devoted to the needs of others over their own private good... which just means that the monstrous things their society does to itself are all perpetrated upon fully-willing people.
  • Humans Are Bastards: While not purely human, the only reason they advanced so quickly is due to neglecting basic morality.
  • I'm a Humanitarian: Corpses are devoured to save resources.
  • Meaningful Name: "Eudaimonia" is a Greek term that roughly means "human flourishing," described in Plato's Virtue Theory of philosophy. The Eudaimoniacs work for the greater good of their society. Of course, the concept is horribly deconstructed.
  • The Needs of the Many: The foundation of their society, and taken to horrific extremes. SCP-752-1 was supposed to reach over 150 years of age naturally, but they willingly work themselves to death in the service of Eudaimonia so hard they're lucky to hit 45.
  • Nothing Is Scarier: Whatever they do in the "nurseries" to rapidly expand their population is horrible enough that Alpha knew the other three science collectives would try to stop the experiment if they ever found out... and is perpetrated upon fully-willing participants.
  • Sealed Evil in a Can: Once Gamma got butchered trying to stop the experiment, and Alpha-3 poisoned most of Beta, Delta and the survivors of the other two collectives joined forces to drive off or kill all of Alpha. They knew they couldn't stop the experiment anymore, so they just sealed the place up as best as they could and hoped that Gamma's shield would be enough to keep them unaware of the outside world forever. And, indeed, the Foundation predicts that their release would result in a SK-class dominance shift, and strictly maintains the quarantine.

SCP-757 - The Fruit Tree

  • Body Horror: When one of the fruits from the SCP is eaten, a new organ forms inside the eater's abdomen, and a fruit forms inside said organ over the course of a week. This has been reported to be painful, and causes tissue damage with larger fruits.

SCP-759 - Sourdough Starter

  • Emotion Bomb: Anyone who eats a product made from a sample of the sourdough gains the emotional state of the individuals that tend it, bake it and feed it.
  • Fan Nickname: In-universe; a batch of muffins made from a sample kept in SCP-682's containment chamber was nicknamed "grumpy muffins".
  • Noodle Incident: It's not revealed what happened when six blueberry muffins that were made from a sample raised and fed under the bed of a newly married agent were eaten.

SCP-761 - Slightly Less Dangerous Trampoline

  • Downer Ending: The recovered document ends with the creator wracked by guilt from the malfunctioning trampoline. This is only made worse by the fact that they were able to figure out there was a problem in time, but his coworkers refused to fix it and sold the trampoline as-is.
  • No OSHA Compliance: The creator of the trampoline wanted to avert this. Unfortunately, the whole deal about kids being materialized into solid material was ignored. The creator himself noticed before it was too late (on the first death, to be exact), but his coworkers simply didn't care. They decided to sell it anyways, knowing that it would continue to kill children:
    they did it wrong. I warned them this would happen. Do they listen to me? No, they go out and sell them anyways. They aren't safe anymore, we know this. All it was supposed to do was take kids off if they were too big or got unruly. But they all go under. It's killing them and nobody is stopping
  • Tele-Frag: When someone jumps on the trampoline they are subjected to Teleportation Misfire and end up in a random location within 15 meters. If there is already a solid object where they arrive they suffer a Teleporter Accident and become merged with the object. Depending on how much of their body is merged with the object they can be inured or killed.
  • Teleportation Misfire: When someone jumps on the trampoline they end up in a random location within 15 meters. If there is already a solid object where they arrive they suffer a Teleporter Accident and become merged with the object. Depending on how much of their body is merged with the object they can suffer a Tele-Frag.
  • Teleporter Accident: When someone jumps on the trampoline they are subjected to Teleportation Misfire and end up in a random location within 15 meters. If there is already a solid object where they arrive they become merged with the object. Depending on how much of their body is merged with the object they can suffer a Tele-Frag.
  • Teleporters and Transporters: SCP-761 can teleport anyone who jumps on it and demonstrates several common problems with teleportation devices while doing so.

SCP-762 - Immortal Iron Maiden

  • And I Must Scream: Anyone that is placed inside the iron maiden is placed in a state of suspended animation until they are released from it. However, they remain conscious, and the experience of being inside it is described as being very painful.
  • Healing Factor: When the person originally inside it was removed, the injuries caused by the maiden's spikes healed instantly.
  • Really 700 Years Old: The Foundation speculates that the original subject was trapped in the maiden for centuries, due to it dating back to the 15th century.

SCP-763 - Human Beowulf Cluster

  • Blob Monster: SCP-763 is a mass of human tissue that spreads over about 300 square meters and weighs more than four metric tons. It is made up of muscular tissue, blood vessels, blood and multiple examples of human organs.

SCP-764 - The Obscene Show

  • Artifact Domination: When anyone looks at SCP-764-1 and SCP-764-2 (Punch and Judy Hand Puppets) with no barrier between them, they are compelled to don the Hand Puppets and put on a show. Everyone else nearby is forced to act like an audience member.
  • Hand Puppet: SCP-764-1 and SCP-764-2 are Punch and Judy puppets that can use Artifact Domination on anyone who looks at them.
  • Puppet Shows: SCP-764-1 and SCP-764-2 (Punch and Judy Hand Puppets) make anyone who looks at them put them on and put on a show.

SCP-769 - Ancient Encyclopedia

  • Discard and Draw: When a person drinks from the cup, they have new information written into their brain, but they lose memories they already have.

SCP-772 - Giant Parasitoid Wasps

  • Big Creepy-Crawlies: They're giant wasps that are 60 centimeters long as adults.
  • Face Full of Alien Wing-Wong: SCP-772 implants 5-20 eggs into large mammals (such as human beings) using a barbed ovipositor up to 70 centimeters long. The eggs hatch 4-12 days later and the larvae start eating their way through the body.
  • Immune to Bullets: The Apocalyptic Log of the scientist that discovered them and the Foundation's report say that SCP-772 is not harmed by bullets.

SCP-777 - Kingdom of Sand

  • Hive Mind: The article notes that the sand animals behave as such; they don't attack each other, but work together to kill any intruders.
  • Silicon-Based Life: Of a sort; when water is added to sand within the SCP's area, the sand will animate and take the shape of an animal proportional to the amount of sand moisturized.

SCP-783 - Baba Yaga's Cottage

SCP-794 - Desert Shipwreck

  • Blob Monster: SCP-794-02 is a living mass of nervous tissue, which grows whenever someone dies near it, presumably by integrating their nervous systems, as said victims' nervous systems are missing.

  • "Instant Death" Radius: Anyone who enters the ship's cargo hold (which contains SCP-794-02) dies immediately.
  • Telepathy: Anyone within 1400 metres of the shipwreck is compelled to enter it.

SCP-795 - Reality-Bending Cat

  • Animal Jingoism: He hates dogs to the point where he had all the dogs at the animal shelter he was found at euthanized and turns humans he considers friends into cats.
  • Baleful Polymorph: He turns creatures into prey animals if he thinks they're dangerous or enemies, luckily it wears off an hour after leaving his presence.
  • Cats Are Mean: Played with. He's only mean to people he considers unfriendly or dangerous, people he does like he'll play with (after turning them into cats).
    • Although it's completely straight if you happen to be a dog.
  • Cats Are Superior: It's implied that he seems to think so.
  • Contagious Powers: Any other cats in his presence also gain his powers, though it wears off 3 hours after being separated from him. Whether this is at will or automatic is up for debate.
  • Reality Warper: Albeit a very small-scale one having only a 30 meter range of effect.
  • Super Empowering: When other cats are nearby, SCP-795 gives them its own powers. The powers last for up to 3 hours after they leave his presence.
  • Telepathy: He can send telepathic suggestions to people around him, usually for things like more/better food or being let out.

SCP-799 - Carnivorous Blanket

Advertisement:

    800-899 
SCP-802 - Musical Tank
  • The Alleged Car: 802 is missing it's turret, is run through with rust, and bears several battle scars.
  • Gauls With Grenades: 802 is a Char B1 bis heavy tank, manufactured in the interwar period in the 1930s. The tank was designed to function as the main thrust of an armored push, but was rendered obsolete by the time the war began.
  • It Can Think: The file notes that the Foundation isn't sure whether or not 802 is actually sapient. While it does patrol the village and responds to threats, no one knows if this is from "instinct" or because it recognizes trespassers.
  • My Greatest Failure: Implied; the tank patrols the ruins of a long-abandoned French village lost during WWII.
  • Tank Goodness: Beaten up and lacking a lot of what made it dangerous, but still a fearsome weapon of war.

SCP-805 - Poison Wood Foal

  • And I Must Scream: It is theorized that the victims are still alive after being converted to wood, due to them creaking and groaning as if attempting to move.
  • Bloody Horror: While the victims are being converted to wood, their blood is forced out of their various orifices, such as their eyes and fingernails.
  • Body Horror: Anyone who touches it has their body converted to wood over the course of 3 to 8 hours, and the process is described as extremely painful.
  • Exactly What It Says on the Tin: It's a foal composed of wood of a species similar to poison oak.
  • I Just Want to Be Loved: When a photo of it was taken using SCP-978 ("The Desire Camera"):
    Photo Result: Being patted and hugged by smiling humans, one of whom is astride its back.

SCP-811 - Swamp Woman

  • Adorkable: She can come off as this in her interview log.
    Skin… [prods her arm thoughtfully, then smiles] skin.
  • Big Eater: She apparently likes bovine prey since she requested regular delivery of them.
  • Bizarre Alien Biology: She has an incomplete digestive tract, absorbs nutrients through her skin, and has liquid rot for blood. Furthermore, her only method of voiding waste is to vomit. She also uses this to hunt.
  • Bloody Murder: The aforementioned liquid rot in her veins is pretty toxic, although she doesn't deliberately use it as a weapon.
  • Body Horror: Aside from the obvious (read: everything else in her entry that isn't Creepy Cute), her personal account of how she became what she is now was apparently quite painful and involved vomiting up all the blood in her system.
  • Cute Monster Girl: In an Ugly Cute sorta way, due to her mannerisms in her interview log. She also likes turtles.
  • Eloquent in My Native Tongue: Doesn't have a "native tongue", per se, but it's apparent that she has complex thoughts and is frustrated by her inability to express them well.
  • The Grotesque: Her description makes her sound like a hideous and repulsive creature who's very presence is a hazard to your health, but her docile nature, child-like demeanor and tragic past make you want to risk contracting gangrene just to give her a hug.
  • Make Them Rot: Constantly secretes a mucus that does this out of the palms of her hands and the soles of her feet.
    • The foundation even tried to use it to melt SCP-682. They didn't put her in the chamber with him, for obvious reasons; instead they just scraped some of it off of her hands and feet over a period of time so they could spray it on him. Naturally, it didn't work.
    • Walking Wasteland: The plants in her enclosure are not immune to this; they are just very good at growing back afterward, and she's smart enough to give them time to heal.
  • Manchild: Seems to be this due to her mode of speech.
  • Mercy Kill:
    "Prognosis for personnel who have had contact with SCP-811's waste through a mucous membrane or open wound is good if broad-spectrum antibiotic therapy is begun in the first three hours, but then rapidly declines. Personnel who are D-Class or have gone 12 hours without getting treatment may request termination."
  • Non-Malicious Monster:
    • Most of the time. Despite her predatory nature, she's rather genial, cooperative and even somewhat cheerful with foundation personnel, likely because they feed her and look after her.
    • She also likes turtles and asked for one as a pet. It was denied, although turtles were removed from her dietary rotation.
  • Pinocchio Syndrome: As shown in the experiment with SCP-978.
  • Poisonous Person: Her digestive mucus, which she secretes from her palms and feet, rapidly reduces organic tissue into black liquid, her vomit is full of deadly bacteria, and surgery cannot be safely performed on her because it's impossible to maintain a sterile operating environment. Even her sweat is a "mild skin irritant".
  • Super Spit: SCP-811 can spit a toxic substance at a target while hunting. The target dies from either asphyxiation from having its breathing blocked or a devastating bacterial infection.
  • Tomboy with a Girly Streak: Kind of. While she's by no means a Girly Girl, for obvious reasons, she does seem to have feminine personality traits, such as a fondness for flowers (as evidenced by her asking for a specific type of flower for her enclosure) and cares about her hair (as evidenced by her asking for a hair brush and someone to wash her hair every other day). According to SCP-978, her preferred clothing would be a sundress, and she would like to braid ribbons into her hair.
  • The Tooth Hurts: Due to her regularly vomiting to void waste, she suffered from chronic tooth pain and requested to be relieved of it. The foundation complied by removing all of her teeth and supplying her with dentures.
  • Tragic Monster: Her backstory is every bit as sad as it is nauseating.
  • Vomit Indiscretion Shot: See Bizarre Alien Biology above. Poor Research Assistant Watchel gets one, too.
  • Was Once a Man: Well, a little girl. She explains (in her own way) that she's this in her interview log.
  • Why Did It Have to Be Snakes?: She doesn't like crocodiles as food and requested they be taken off of her dietary rotor. Perhaps she didn't like that they bite back.
  • Wild Child: She has the mentality of a predatory animal. As long as she isn't frightened, threatened, or hungry, she's quite docile and safe to deal with.
  • You No Take Candle: "Dockty. What want?"

SCP-819 - Vital Suckers

  • Eye Scream: When a blue SCP-819 is consumed the liquids in the eater's eyes are sucked out (causing permanent blindness) and transferred to the eyes of another person. The recipient's eyes burst from the increased pressure and may become dislodged from the eye socket.
  • Rainbow Motif: When consumed, these lolipops drain liquid from the victim's body. The type of liquid consumed depends on the lolipop's color: red (blood), orange (gastric acid), yellow (urine), green (phlegm), blue (aqueous and vitreous humors) and purple (cerebrospinal fluid).

SCP-823 - Carnival of Horrors

  • Cruel and Unusual Death: The majority of the deaths in this park is horrifically violent. Some examples include a mascot found dead of suffocation, a group of people found decapicated on the rollar coaster, a couple fused together on the ride, and a mutilated man found in the Hall of Mirrors.

SCP-826 - Draws You into the Book

  • Portal Book: SCP-826 is two bookends. When a book is placed between them, the room it's in will change into the setting of the book. Anyone who enters the room will enter a random location in the book's setting. Any actions the explorer takes will be reflected in the book after they leave it.
  • Theory of Narrative Causality: Averted, testing has shown there is nothing stopping those who enter the stories from radically altering their outcome. Attempts to exploit this trope by placing SCP-682 in the 12-page The Generally Nice, Friendly Thing That Can And Will Kill SCP-682 Permanently if it So Much As Spots That Damn Lizard resulted in the 209-page The Generally Nice, Friendly Thing That Tried To Kill SCP-682 Permanently But Failed.
  • Year Inside, Hour Outside: A person can spend hours inside the book while only minutes pass outside.

SCP-827 - The Soup

  • Blob Monster: What Dr. George Farrow turned himself into while trying to cure his cancer with stem cell therapy.

SCP-834 - Marked

  • Animated Tattoo: Approximately 6 months after a SCP-834 marker is used to draw something on a human body, the drawing animates and attacks the victim.
  • Chest Burster: A researcher used a SCP-834 marker to drew reptilian scales on their chest. Six months later their internal organs were converted into a reptile-like monster and burst out of their chest.
  • Logical Weakness: The things that are created by a SCP-834 marker's ink can be destroyed by water (or water-containing substances like blood) because the ink that creates them is water-soluble.

SCP-835 - Expunged Data Released

SCP-839 - Candied Worms

  • Bizarre Alien Biology: The worms are made of sugar, coloring and flavoring, but are somehow alive.
  • Exactly What It Says on the Tin: They're worms that are made up of sugar, flavor and coloring.
  • Eye Scream: The Green-flavor worm will slowly eat one of the eater's eyes and replace it.
  • Hallucinations: The Green-flavor worm (which replaces one of the eater's eyes) causes mild hallucinations.
  • Kill and Replace: Or rather "Eat and Replace", since if one of the worms is eaten by any mammal, it will eat an organ and replace it; the organ replaced depends on the flavor of the worm.
  • Nothing Is Scarier: The other effects of eating the Watermelon-flavor worm (which replaces the brain) have been expunged.
  • Rainbow Motif: SCP-839 are candy worms that, when eaten, replace one of the body's organs. The worms come in different colors: red ♥, orange (liver), yellow (stomach), green (one eye), blue (one kidney), and purple (one lung). Indigo is replaced by pink (brain).

SCP-843 - "Cow Seeds"

  • Nuke 'em: Presumably what its "Atomic Grenade" is.
  • Zeerust: It closely resembles a 1950's-style toy robot.

SCP-847 - The Mannequin

  • Extreme Doormat: It acts very submissive and docile towards males, allowing them to pose it in any way they want. This is also very apparent in the messages it scratches out:
    YOU CAN OWN ME
    YOU'RE MY MASTER
    WHATEVER YOU WANT
    I CAN BE YOUNG FOR YOU
  • Human Resources: It will replace any shattered body parts with the parts of women who have been affected by its resin.
  • Ms. Fanservice: In Pattern Z behaviour, it prefers to wear clothing for young women that leaves ample skin exposure, and will adopt a pose that best showcases the chosen outfit.
  • Please Don't Leave Me: Its message from 6/8/2001 reads "DON'T LEAVE ME".
  • Self-Harm: It'll shatter any parts of itself that a man who spends time with it finds undesirable or outdated.

  • Slasher Movie: The Hall can enter many different Genre modes, including that of a horror film.
  • Stuff Blowing Up: Numerous explosions were reported while the Hall was in Action mode.

SCP-859 - Arachnophobic Orb

SCP-860 - Blue Key

  • Easter Egg: Listen to the sound files... or better yet, don't. I SEE YOU!
  • Fog of Doom: The forest is shrouded in blue fog. It turns red during the fourth expedition.
  • Glowing Eyes of Doom: A pair of eyes are briefly visible through the fog at the end of the fourth expedition.
  • The Lost Woods: A much creepier example than normal.
  • Year Inside, Hour Outside: A 27 year old female spent 7 months inside the blue forest and emerged a very old woman, indicating that time passed faster than normal inside it.

SCP-863 - Patchwork Crabs

  • Appendage Assimilation: The title crabs can take a limb from a dead creature, stick it in a slot in their body and use the limb as if it were their own.
  • Giant Enemy Crab: These crabs can grow so large that they can use an entire human body as a replacement arm and use human legs to walk around on.

SCP-864 - Efficient Washbasin

  • Combat Tentacles: When filled with water, SCP-864 can generate tentacles that can grab nearby people.
  • Power Pincers: When filled with water, SCP-864 can generate large (70 centimeter long) pincers that can grasp and try to drown anyone close by.

SCP-865 - The Gentleman's Lash

  • Fake Memories: It causes these in the person that SCP-865 is fired at, and the person in question will even imitate conditions such as brain damage and paraplegia.
  • Laser-Guided Amnesia: It appears to remove traumatic memories in a person if they use it several times.

SCP-896 - Online Role Playing Game

  • Dump Stat: The players avatars' stats reflect on them, and testing has five players focus on five different stats, to the initial exclusion of all others, as the page says:
    D-896-a: Knight - character focus on stamina.
    D-896-b: Berserker – character focus on strength.
    D-896-c: Cleric – character focus on wisdom.
    D-896-d: Warlock – character focus on intelligence.
    D-896-e: Bard – character focus on charisma.
  • Immune to Bullets: One of the test subjects had his Stamina (constitution, resistance to injury, etc.) statistic increased so high that he became immune to bullets from standard issue firearms.
  • No Fair Cheating: The intelligence focused player hacked the game and "vanished from containment".
    Upon reviewing Warlock’s account information contained on SCP-896, researchers discovered a customer service notation simply stating “User has been banned for hacking.”
  • Rapid Aging: A researcher who played the game for less than 10 hours straight leveled up many times but then died. An autopsy showed severe arthritis, Alzheimer’s, a cataract and several tumors, indicating death from old age.
  • Your Mind Makes It Real: Anyone who plays SCP-896 will have their real life attributes increase to same degree that their in-game attributes do. However, if one of a character's attributes rises too high above the others, the player's attributes decrease.

SCP-867 - Blood Spruce

  • Chest Burster: After an SCP-867 seed is injected into a living creature's body, it grows throughout the creature's circulatory system, eventually killing it. SCP-867 then bursts out of the victim's body and grows to full size, consuming the body as it does so.
  • Face Full of Alien Wing-Wong: SCP-867's leaves act like hypodermic needles, injecting a seed into any creature that brushes up against it.

SCP-870 - The Maybe There Monsters

  • Creepy Centipedes: One of the forms that SCP-870 has been seen as is a scorpion with human arms instead of legs.
  • Invisible to Normals: The creatures known as SCP-870 can only be seen by people with schizophrenia. Each schizophrenic person who looks at a SCP-870 sees something different (a spider with too many legs, a giant ant with a human face, etc.).
  • Never Smile at a Crocodile: One of the forms that SCP-870 appears as when looked at by a schizophrenic is an alligator with spider legs and three eyes.
  • You Cannot Grasp the True Form: Schizophrenics can see SCP-870 instances, but their description is inconsistent. A Foundation doctor even hypothesize that even they aren't seeing the whole picture, just slightly clearer than normal people.

SCP-875 - War Criminals

  • Ancient Astronauts: The pictures inside the SCP-875 pyramid indicate that the SCP-875-3 Insectoid Aliens taught the ancient Egyptians how to build the Pyramids.
  • Insectoid Aliens: SCP-875-1 are flying insects that are different from any known Earthly species, indicating that they are from another world. The large creatures in the cryogenic stasis chambers are also insectoid in nature and are presumably from the same source.
  • Poison Is Corrosive: SCP-875-1 are small flying insects about six centimeters long. They have a sting which injects a venom that is highly acidic and does serious damage to tendons and nerves.

SCP-881 - Little People

  • An Aesop: Dr. Dammer learns the hard way not to be needlessly cruel to SCPs.
  • Eye Scream: The miniaturized human beings managed to escape confinement and infiltrate Dr. Dammer's body. The end of his That Was the Last Entry is "whsts in my eye" and a string of random letters, indicating pain and a loss of control due to their attacking his eye from the inside.
  • Incredible Shrinking Man: SCP-881 is 9,891 humans, animals and plants shrunk down to tiny size by the side effects of the destruction of another SCP. They initially ranged from 2 millimeters to 15 centimeters high, but over time some were created that were even smaller.

SCP-890 - The Rocket Surgeon

  • Blue and Orange Morality:
    • He sees machines as his patients and humans as essentially animals.
    • He "operated" on a pacemaker while it was still in its user. Not surprisingly, said user dies from being neglected. His response is that the operation was a success, while ignoring the expiring "mass of flesh".
  • I'm a Doctor, Not a Placeholder: The reason he doesn't operate on humans is because he's "a doctor, not a vet".
  • Machine Empathy: He can "talk" to his "patients".
  • Morally Ambiguous Doctorate: See above.
  • Misanthrope Supreme: Implied. He sees humans as nothing more than "animals" and refuses to operate on them.
  • No Name Given: Only the first letter of his first name is given ("W").

  • Big Eater: SCP-913 must eat the normal daily caloric requirement of a human being every two hours, or he falls into a trance and becomes an Extreme Omnivore.
  • Extreme Omnivore: If SCP-913 doesn't get enough to eat, he will eat any solid matter that he can get his hands on.

SCP-914 - The Clockworks

  • Amplifier Artifact: When on Fine or Very Fine. For instance, a CD became a flash drive, and a printed copy of the Mona Lisa results in a version on either canvas (Fine) or wood (Very Fine, as that is the material of the original).
  • Awesomeness Is Volatile: Items gained from the Very Fine setting have a high chance of breaking spectacularly at some point. Recursively refined items using this setting are increasingly prone to this.
  • Black Box: Nobody's sure how the collection of gears works.
  • Clock Punk: It's made entirely from clockwork parts.
  • Combinatorial Explosion: It has five quality settings, "Rough", "Coarse", "1:1", "Fine" and "Very Fine" and the results are different every time.
  • Equivalent Exchange: The 1:1 setting—the machine converts the item to a similar item of the same quality.
  • Fusion Dance: Generally from two items on the Fine setting. Reversed with the Rough setting, which tends to turn the item back into its raw materials.
  • Godwin's Law: Feeding it Mein Kampf results in a series of increasingly elaborate and creative insults at Hitler's expense, eventually culminating in a doddering and clumsy but entirely animate paper mache model of Hitler that the staff are encouraged to punt with no consequence.
  • Hand Cannon: A Colt Python ran through on the Very Fine setting became powerful enough to completely disintegrate anything it hit.
  • Insufferable Genius: Its "personality", if it even has one, seems to resemble this.
  • It Amused Me: One theory to its purpose is that it's actually a sort of bizarre entertainment device.
  • Literal Genie: At times. Put a E.T. the Extra-Terrestrial video game cartridge on Fine, and it returns a boxed copy.
  • Mad Artist:
    • If it is truly sentient, then is is probably the best way to describe what it does. In the words of Dr. Gears:
    "After extended time spent in research on and with SCP-914, the following proposal regarding its nature may be made with a significant degree of certainty: SCP-914 was not designed as an industrial device. Nor was it primarily a scientific device. Its primary function appears to be as a form of entertainment. After review of the recovery notes, and evaluation of the test logs, it appears that SCP-914 was designed to create the most “novel” items possible, with no regard for practicality or function."
    • If you decide to accept this tale into your headcanon, then SCP-914 certainly takes after its creator.
    • Likewise for this tale, where it tells the Church of the Broken God to take a hike because the Foundation lets it make stuff its owners never did.
  • Serial Escalation: Cumulative/recursive tests — Coarse are refined to the atomic scale, Fine/Very Fine are increasingly improved.
  • Smart People Play Chess:
    Professor "Q": Yes, I've been playing chess with 914… Yes, I'm aware it's supposed to be non-sentient, but that hardly explains why it's winning.
  • Snarky Inanimate Object: When Dr. Hertz put a music album in it containing recordings of songs he had written and performed himself, the resulting output was a CD with chapters from various audiobooks including "Learn to Sing", "Teach Yourself to Play Guitar", and "Songwriting for Dummies". This caused Dr. Hertz to attempt to attack the SCP.
  • Sturgeon's Law: 914's experiment log is open to the public. Naturally, most of the stuff added has had to be deleted.
  • Take That!: Many from the test log, which are full of in-jokes, sly references and the occasional snarky output from 914.
    • One test log on a Samsung Galaxy Note 7, the smartphone with an infamous battery defect that led to devices catching fire or exploding, resulted in a grenade on the 1:1 setting.
    • Feeding it a crossword puzzle resulted in 914 actually responding with frustrated confusion, and then finally ejecting the crossword at high velocity and on fire. The attending researcher notes that he can relate.
    • Likewise, not even 914 can assemble IKEA furniture correctly. Higher levels result in a chair that is almost correct, with evidence that someone had been banging on it in frustration. Trying again on Very Fine with words of encouragement resulted in 914 creating an automaton do to it instead. Said automaton was also unable to do so. Again, the attending researcher expresses sympathy.
    • Putting a Steam gift card through it on Fine results in the user being given Monopoly money.
  • Telepathy: It has at least some ability to read minds. When it was given a silver ring belonging to a D-class that she claimed was a family heirloom, it produced a ring engraved with "In loving memory of" and the name of one of her deceased relatives.
  • Troll: It has shades of one... one of which is apparently pink.
    I hate [EXPLETIVES REDACTED] pink! — Dr. Hale
  • Up to Eleven: The end results of the Very Fine setting break as much physical laws as they can get away with, usually with at least one casualty. Some are nearly given their own SCP classifications. Its greatest desire, as seen with SCP-978, is to have a setting even higher than that.

SCP-915 - The Mechanotesseractic Computer

  • Alien Geometries: The interior of SCP-915 has a highly non-Euclidean internal configuration, with extensive outpocketing in space and time and a locally nonflat spacetime. The interior experiences constant shifts and is mentally unsettling to anyone inside it, often causing disorientation, nausea, and fainting.
  • Bigger on the Inside: SCP-915 is a metal cube 1.3 meters on a side. Anyone passing inside finds it to be much larger, and can wander around for months.

SCP-916 - Man's Best Friend

  • Driven to Suicide: The voices attempt to persuade a person near the SCP to do this.
  • Exactly What It Says on the Tin: Subverted. It's a dog that causes the elimination of pain in any nearby person, and dogs are typically referred to as "man's best friend". However, said person also starts hearing voices that attempt to persuade them to commit suicide.
  • Hearing Voices: Anyone who stays with the SCP for over 15 minutes starts hearing voices that talk about how it eliminates their pain, and then attempts to persuade them to commit suicide.
  • Immortality: The SCP seems to be immortal, as it's a golden retriever that was recovered in 1977 and is still alive, but ordinary golden retrievers live for 10-12 years on average.

SCP-917 - Mr. Moon

  • Facial Horror: As the new moon phase occurs, his facial features disappear.
  • Lunacy: His facial features appear and disappear according to the lunar cycle.

SCP-918 - Baby Mill

  • Delivery Stork: Inverted. The SCP creates storks that steal babies and turn them into talcum powder.

SCP-920 - Mr. Lost

  • Charm Person: People who see him feel a strong compulsion to "walk and talk with him". This invariably gets that person lost, possibly even dead due to thirst or starvation.
  • Contrived Coincidence: An attempt to take SCP-920 to a location will fail, possibly because of an astounding coincidence.
  • Idiot Ball: If someone tries to move SCP-920 to another location the attempt will fail. One way this can occur is the people picking him up making very stupid decisions on where to go, causing them to all become hopelessly lost.
  • The Needless: Doesn't seem to need food, water, sleep, or anything else that a normal human being would need. He's been spotted wandering through vast deserts, tundras, and even oceans without any apparent difficulty.
  • No Sense of Direction:
    • He has no control over his own movements, causing him to wander aimlessly. As such, he can't follow any directions to get places.
    • It's impossible to contain him for long. Lock him in a room, and he'll suddenly reappear five miles away, completely lost. Again.
    • Being in his presence also appears to induce this in others.
  • Perpetual-Motion Monster: He's a man, but fit this trope nonetheless. Doesn't seem to need food, water, sleep, or anything else that a normal human being would need. He's been spotted wandering through vast deserts, tundras, and even oceans without any apparent difficulty.
  • Scannable Man: Not a barcode, but a label tattooed on his left calf. "Mr. Lost from Little Misters ® by Dr. Wondertainment".
  • Walking the Earth : He's called Mr. Lost for a reason, and he sends people he talks to on similar journeys, although unlike him they can get un-lost (if they don't die of thirst or starvation first, that is).
  • Walking Techbane: Any attempt to lead SCP-920 somewhere using a technological device (such as a GPS system) will cause that device to fail. In fact, the Foundation has to use satellites to track him because tracking him through other means (such as helicopters) failed due to his abilities.

SCP-925 - The Mushroom Cultist

  • Brainwashed: Anyone who makes physical contact with an instance of SCP-925 gradually becomes one of its followers.
  • Hermaphrodite: Instances of the SCP have been described as apparently being true hermaphrodites. However, they have never been observed reproducing.
  • The Stoner: They have been described as acting as if they were inebriated or impaired. This appears to be deliberate.

SCP-929 - The Cuckoo

  • Animalistic Abomination: It was contained by the Foundation as a blackbird chick, before Incident 929-1 caused them to contain it as a goldfish instead.
  • Brainwashed: It convinces its "parent" that it is the "parent's" offspring, going so far as to produce detailed memories of their "child". This got to the point that the "parents" attacked Foundation personnel while it was being contained in the form of a blackbird chick, allowing it to attempt to breach containment.
  • Combat Tentacles: When SCP-929 is attacked, its head will split open and tentacles will emerge from it. SCP-929 uses these tentacles to strangle, strike and lash its attackers.
  • Voluntary Shapeshifting: When SCP-929 comes within three meters of an animal it will rapidly change into a younger version of the animal. It will stay in that form until the animal it's imitating dies or it's attacked.

SCP-930 - Seagull Island

  • Good All Along: The entry primarily describes how all birds of the island viciously attack any and all people that approach, but the enclosed document indicates that they're trying to warn people away from the island because something else lives there, something very unfriendly to humans.
  • Glowing Eyes of Doom: Take a close look at the last photo.

SCP-931 - A Rice Bowl

SCP-932 - Night Feeder

  • Air-Vent Passageway: During the containment breach described in Incident Report 932-02 SCP-932-06 escaped, apparently by somehow getting into Site-09's air ducts. While in the air ducts it reproduced, creating SCP-932-07 and SCP-932-08.
  • Emotion Eater: These creatures find a sleeping person, pin them down and wake them up. They then consume the fear the victim feels at the situation they're in.
  • Vampiric Draining: If the creatures are not fed they will attack people who are awake. This will so severely drain the victim that they will be rendered comatose and eventually die of a heart attack. The draining process has the side effect of allowing the creatures to reproduce.

SCP-934 - Inland Lighthouse

  • Exactly What It Says on the Tin: It's a lighthouse that's far inland, away from any body of water.
  • Fog of Doom: The area around it becomes surrounded by a thick fog every week, and anyone who enters the fog is never seen or heard from again.

SCP-939 - Of Many Voices

  • Voice Changeling: They can perfectly imitate any human voice and speech, even those of people they haven't even encountered.
  • Was Once a Man: It at least seems so. SCP-939 are capable of reproduction, and their offspring are indistinguishable from ordinary human children.

SCP-940 - Araneae Marionettes

  • Face Full of Alien Wing-Wong: SCP-940 reproduces by having its host rape other people, which infects the victim with SCP-940 eggs. The eggs grow inside the victim and eventually take it over, continuing the cycle.
  • Giant Spider: SCP-940 is a spider-like creature with a leg span up to 7 meters across.

SCP-943 - Repayment in Kind

  • Flashed-Badge Hijack: In the Back Story, a Foundation Agent was killed by a civilian while he was trying to commandeer the civilian's car to deal with a containment breach of another SCP object.
  • Hallucinations: When SCP-943 is put on a subject's wrist, they start to suffer from visual, auditory, and tactile hallucinations that are based on their guilty feelings about something they did.

SCP-944 - Mirror Maze

  • Hall of Mirrors: SCP-944 is one of these where weird things happen when people step through the mirrors.
  • Magic Mirror: A number of mirrors in the Fun House section of SCP-944 have strange effects on people who pass through them, such as being teleported to another mirror 700 miles away, being squashed down to a height of 3 foot 4 inches, and being trapped inside the mirror.
  • Mirror Monster: A child went through one of the mirrors in SCP-944 and ended up in a windowless brick room being tortured by "Zippo the Pyromaniac Clown".

SCP-953 - Polymorphic Humanoid

  • All Myths Are True: The Sole Survivor of the team sent to capture her only does so because he remembers the tales his grandmother told him (note the similarity between the After-Action Report and the tale of The Fox Sister). While a Foundation scientist ridicules the idea in favor of a more scientific approach, several escape attempts causing fatalities convince everyone concerned that this folklore needs to be taken seriously, and may well have been a crude version of Special Containment Procedures.
  • And Show It to You: When one of the agents was sleeping with her, she sadistically tore off his testicles and showed them to him before killing him.
  • Ax-Crazy: She is hostile to human life and extremely dangerous. She can penetrate a person's abdomen with her hand and extract the victim's liver, but prefers to slowly torture her prey.
  • Berserk Button: Being called a kitsune. "Personnel asking what the difference is are to be reminded of the difference between a Cherokee Indian and a New Delhi Indian". Furries also piss her off, and she's been on record as killing 27 attendees of a furry convention.
  • Call a Pegasus a "Hippogriff": Invoked In-Universe. Kitsune and kumiho are similar in appearance, but not so much behavior. The distinction is a major plot point in the capture report. The Korean agent is aware that kumihos are Always Chaotic Evil, which ends up saving his life. The Japanese agents, on the other hand, think of 953 as a kitsune, who may be friendly and even form a bond with a human. Guess how well that turns out for them.
  • Charm Person: Has somewhat weak mind manipulation abilities, but those who fall under her sway will more or less do anything she asks. These things include roasting and cannibalizing one's own child, allowing her to perform necrophilia upon the corpse of an entranced person's fiancé in full view, and succeed in serial murder with zero repercussions, among other effects.
  • The Fair Folk: This is technically what a kumiho is, but her sheer malevolence makes the Court Unseelie look perfectly benign by comparison.
  • Fantastic Foxes: She's a Korean fox — a Kumiho, not a Kitsune.
  • Glowing Eyes of Doom: Has glowing yellow eyes, regardless of its form. See Morphic Resonance.
  • Hair-Trigger Temper: Of the Revenge variety. She has a fantastic memory and remembers anyone who has caused any slight to her and tries to enact revenge on them the first chance she gets. Also the main reason some of the Foundation staff are trying to get higher security to contain her than the dog kennels listed below.
  • Horny Devils: Violently murders a team member during sex, and it's suggested that the only survivor of the massacre has an unhealthy fascination for her. You should keep the Furry Fandom away too.
  • Humanoid Abomination: When she's taking a human form.
  • I Love the Dead: Has, on at lest one occasion, used the powers of Charm Person to perform acts of necrophilia upon an agent's fiancé in full view of said agent. Whether this was out of preference or spite is unknown.
  • Insistent Terminology: She's not a kitsune, she's a kumiho. As noted above, the two are as different as a Cherokee Indian and a New Delhi Indian. Not only are kumihos from Korea, they are Always Chaotic Evil, always female spirits who need to consume human hearts and livers for survival. Basically the only similarity is that both are shapeshifting fox-spirits with illusionary powers.
  • Made of Iron: Can take gunshots from a .45 with little issue. However, it is assumed by the Foundation that she can be killed with guns anyway in an emergency.
  • Morphic Resonance: Any form she takes has some fox-like features (ears, tail, paws, yellow glowing eyes, fur, voice, mannerisms).
  • Multiple-Tailed Beast: Has nine tails.
  • Picky People Eater: SCP-953 can reach inside a person's abdomen, extract their liver and swallow it whole.
  • Psychic Powers: She has the psionic powers of suggestion and telepathy.
  • To Serve Man: Like the mythological kumiho she resembles, she has a preference for the heart and the liver, but will eat any human flesh she can get.
  • Telepathy: SCP-953 uses its telepathic ability to find out what its opponents' loved ones look like. It then uses its Voluntary Shapeshifting ability to take the form of one of the loved ones.
  • The Trickster: in-between eating humans, she loves to play sick tricks on them, seemingly purely For the Evulz. She tricks a mother into eating her own child. Also, when a team of agents arrives to apprehend her, she mentally dominates them and feeds them meat with rice... only the meat turns out to be rotting human flesh, and the rice is live maggots.
  • The Vamp: She seemingly exploited this to bite off an agent's genitals, before showing it to him and proceeding to tear out his liver.
  • Voluntary Shapeshifting: SCP-953 normally has the form of a small Red Fox, but can take the form of objects and living creatures, including that of an attractive Korean woman.
  • Weaksauce Weakness: The Immune to Bullets murderous fox demon turns into a quivering, terrified wreck at the sight of dogs.
  • Why Did It Have to Be Snakes?: She has a fear of dogs so her containment procedures involve her containment chamber be lined with open-cage dog kennels.
  • Yamato Nadeshiko: Invoked at times to increase her mental hold over her victims. The after-action interview actually notes that [Agent 1] calls her this explicitly, though the data is blacked out.
  • Yellow Eyes of Sneakiness: To add to her fox-like manner.

SCP-955 - Mr. Sillybug

  • The Grotesque: SCP-955 is overtly friendly, behaving in a similar manner as a young dog. This is in spite of it's frightening appearance
  • Poison Is Corrosive: The substance spit out by an example of SCP-955 is both corrosive and poisonous.
  • Super Spit: If an example of SCP-955 is startled or feels threatened it will spit out a highly caustic mucus up to several meters away. The mucus contains a pain-causing neurotoxin.

SCP-956 - Child Breaker

  • And I Must Scream: Its effect on its victims. They're rendered paralyzed and incapable of speech before it bashes them open. Sadly, it's been determined that even if you get a victim away from the thing before it can kill them, they're stuck that way for what will likely be a much shorter life.
  • Baleful Polymorph: Children who eat the candy it makes turn into more murderous piñatas.
  • Body Horror: The candy it creates when it bashes open children are made out of the child's organs.
  • It Can Think: As of recently, SCP-956 has started to wander around its containment cell and is staring at a spot on one of the walls. Security confirmed that it is facing directly towards a nearby elementary school.
  • Living Toys: A living, murderous piñata.
  • Logical Weakness: Being a piñata and made of paper, it can be destroyed by fire.
  • Made of Iron: It is, however, inexplicably resistant to huge amounts of bludgeoning damage. No baseball bat is going to get this piñata open.
  • Names to Run Away from Really Fast: "Child Breaker".
  • Russian Reversal: In Soviet Russia, piñata beats YOU!
  • Would Hurt a Child: Would bludgeon children to death until candy spills out of their innards.

SCP-957 - Baiting

  • The Bait: Uses the humans it turns into instances of SCP-957-1 as this, luring other humans to its home to dismember them. The translated conversation at the end of the article implies that SCP-957 itself is this, just serving as a huge distraction to the Foundation so its unknown friend can do what they want.
  • Body Horror: It looks like a tall mummified corpse with jagged teeth and unusually large eyes.
  • Brainwashing: Has this effect on its victims, who are thereafter referred to as instances of SCP-957-1. After the brainwashing SCP-957-1 have their eyes taken out but believe they have always been blind and regard SCP-957 as a close friend, who they help by feigning needing help in public and when someone helps SCP-957-1 home they fall prey to SCP-957.
  • Humanoid Abomination: Even with its disturbing appearance aside it definitely has supernatural abilities such as Super Strength, can trap victims in a Pocket Dimension it its chest cavity to brainwash them, and can surround itself and victims in an impenetrable black barrier.
  • Implacable Man: Due to its abilities and Super Strength the Foundation has no way of preventing it from doing what it wants.
  • Loner-Turned-Friend: SCP-957 specifically seeks people who live alone to turn into instances of SCP-957-1 and becoming their "friend".

SCP-959 - The Bogeyman

SCP-961 - University Sundial

  • Eyeless Face: SCP-961-1 is a human who is described as having empty black apertures where the eyes should be.
  • Hallucinations: Anyone caught within the sundial's area of effect when it is active experiences vivid hallucinations relating to a significant historical event.

SCP-962 - Tower of Babble

  • Body Horror: The animals it turns into "servitors" have had extensive modifications to make them appear more human-like.
  • Bold Inflation: The excerpt from one of its documents contains a few of these:
    Cleanse the WORLD for the Great Ones Cleanse the WORLD for the Great Ones
    who greater than you your majesty your sublime nature Great Ones do I do right?
  • Cyborg: It turns animals into these.
  • Humans Are Special: It appears to think so, as it refers to humans as "Great Ones", its rants consistently praise humans and its servitors are made to look human and don't attack humans or machines.

SCP-966 - Sleep Killer

  • Invisible Monsters: Can only be seen through infrared filters.
  • Monstrous Humanoid: They are humanoid in shape, but they act more like animals.
  • Paranoia Fuel: In-Universe. On occasion, they will subject prey to threatening noises and physical assaults to compound the sleep deprivation with additional stress, speeding up the victim's deterioration.
  • Super-Persistent Predator: Justified by their method of subduing prey. They emit a sort of radiation that renders victim unable to sleep, then follows said victim around until they finally succumb to sleep deprivation.
  • Wolverine Claws: Subverted. They have long nails, but being easily broken, they make for poor weapons.
  • Unholy Matrimony: Kind of; The extended testing logs for SCP-978 reveals that what 966-1 wants most is to mate with 966-2.

SCP-967 - Infinite Scrapyard

  • Bigger on the Inside: From the outside SCP-967 appears to be an scrapyard about 200 meters by 500 meters. On the inside it is much larger, being described as consisting of "trash as far as the eye can see".
  • Kill It with Fire: When the primitive robots that exit SCP-967 break apart into their component pieces, the Foundation burns them to ashes and puts them back inside SCP-967 so their presence outside SCP-967 doesn't cause it to expand.

SCP-968 - Tar Baby

  • Alluring Anglerfish: SCP-968 hunts humans by altering part of itself to mimic a baby or small child to lure in rescuers.
  • Blob Monster: Since its lack of solid parts limits its mobility, trying to freeze it actually makes it more dangerous, as it can use the frozen parts to act as "bones".
  • To Serve Man: SCP-968 hunts humans by taking the form of a small child or baby.

SCP-970 - The Recursive Room

  • Alien Geometries: SCP-970 is a collection of rooms that are connected by a series of doors in a straight line. If a person walks through the doors in order, they'll end up back at their starting place.
  • Alternate Universe: Anyone who passes through all of the doors in SCP-970 and ends up in their original location will actually be in a slightly different universe. Each time they pass through SCP-970 the universe will change a little more, until things get really strange.

SCP-973 - Smokey

  • Ax-Crazy: He hunts down people who are speeding and inflicts horrible painful deaths on them.
  • Bald of Evil: He appears to be a balding Caucasian male. He ruthlessly kills speeders in horrible ways, including evisceration and rape.
  • Disproportionate Retribution: He horrifically murders people for speeding. Even worse, the speed limit he enforces isn't even consistent.
  • Fat Bastard: Described by the Foundation and witnesses as "overweight".
  • Humanoid Abomination: Especially after the Foundation tried to destroy the road he originally patrolled.
  • Rabid Cop: Exaggerated. And he's a traffic cop, too.
  • Rape Is a Special Kind of Evil: Aside from brutally dismembering his victims, he will also rape them.
  • Red Eyes, Take Warning: After he relocated following the demolition of his road.

SCP-974 - Treehouse Predator

  • Face Stealer: After killing and eating a human being it can take the form of that person.
  • Humanshifting: It can take the form of any human being that it has killed and eaten.
  • Immune to Bullets: Combat between Foundation troops and SCP-974 has shown that it isn't affected by small arms fire.
  • Monstrous Humanoid: SCP-974 is a meat-eating creature that looks like a young human child.
  • To Serve Man: In its standard form, SCP-974 lures groups of prepubescent children to its treehouse, then kills and eats one of them. In its enhanced form it can kill and devour adult human beings.
  • Super Strength: SCP-974-A (what SCP-974 turns into when it isn't fed children) is strong enough to rip the steel roof off of a building.
  • You Are Who You Eat: While in its standard form, after SCP-974 kills and eats a child of age 6-12 it will change to that child's form over a period of 10-12 days. In its enhanced form it can kill and devour adult human beings and take their form in a short period of time.

SCP-978 - Desire Camera

  • Magical Camera: When it takes a photograph of a person, the photograph is not of that person but of what that person wants to be doing at that time, often revealing secrets about that person they otherwise didn't want let out.

SCP-983 - The Birthday Monkey

  • Do Well, but Not Perfect: One person managed to score 45 out of 46. The candy made her explode in a flash of white light, and they never found the body. It's implied that instead of dying, she transformed into some sort of Energy Being.
  • Rapid Aging: Each time the Birthday Monkey sings a verse the person who activated it will age 1 year. If it isn't deactivated the victim will be aged to death. The Monkey will continue singing verses until the victim has been reduced to a skeleton.

SCP-990 - Dream Man

  • Affably Evil: If he's responsible for the events in his warnings, he's a remarkably sporting and fair creature.
  • Ambiguously Evil: It's unclear whether his predictions of catastrophic events are threats or just helpful warnings.
  • Dark Is Not Evil: He's a Keter-class man wearing a black suit who only shows up in nightmares... and is only classified as Keter because he is absolutely uncontainable and anything he warns about always requires urgent attention. Otherwise he's a perfectly Nice Guy that tells people about future dangers.
  • Dreaming of Things to Come: His purpose, more or less, is to clear up the symbolism of prophetic dreams and bluntly tell people what's going to happen. Whether he causes this is unknown.
  • Greater-Scope Villain: Warns the interviewer about an unknown female SCP that he refers to as "the bad guy." When the interviewer tells him there's no such SCP by that number, he replies that she hasn't been born yet, but ominously adds "She will."
  • Our Founder: In the Competitive Eschatology canon, he's the founder of the Foundation. It's unknown how or why he became anomalous, if he wasn't to begin with.
  • The End of the World as We Know It: Competitive Eschatology canon again. He's a World Ender, one of the deific figures summoned by the Harbringer to end the world. Unlike Yahweh, Fenris, Yaldabaoth and others, however, he's trying to make sure humanity comes out on top.
  • The Rival: In Competitive Eschatology, his relations with current Foundation administrator is... Strained.
  • The Men in Black: The most striking feature people remember about him is that he looks like this, with his "Cold War era business suit".
  • Nice Guy: A little morbid and strange to be certain, but he only showed his existence to the Foundation to help them stop a nuclear war and seemed genuinely perturbed when his chosen "prophet" for that died.
  • Noble Demon: If he's responsible for the events in his warnings, he's a remarkably sporting and fair creature.
  • Screw Destiny: His ultimate goal, it seems, is to stop a more hostile SCP who hasn't been born yet, and he helps people do this himself.

SCP-992 - Gaia's Emissary

  • I Know Your True Name: SCP-992 has the mystical ability to know the true names of things, including living things such as human beings (both living and dead) and plants. He is able to create things he has named, including unusual weather and the Aurora Australis.
  • Magical Native American: 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.

SCP-993 - Bobble the Clown

  • Ax-Crazy: Bobble loves murder, torture, arson, cannibalism, and [DATA EXPUNGED].
  • Big Bad: Could potentially become this, considering what he's currently planning.
    In the episode [[EXPLETIVE] YOU [EXPLETIVE] YOU [EXPLETIVE] YOU], Bobble the Clown angrily details methods of breaching containment for several SCPs. Bobble then details methods to murder researchers involved in its containment, showing detailed knowledge of their daily routines and habits.
  • Brainwashed: Anyone under 10 who watches the show will regularly do the things he teaches them (arson, cannibalismn, etc) until the Foundation erases all memories of the show from the child's mind.
  • Corrupt the Cutie: Kids who watch enough episodes of Bobble's show develop psychotic and schizophrenic tendencies. In Behind the Scenes, he claims that he's "been making little savages for quite a while now".
  • Depraved Kids' Show Host: What else can you call a kid's show host that teaches kids to murder, torture and stalk people?
  • Eldritch Abomination: A sentient TV show. What's more, it claims to have had attempted existing in previous forms (wrap your head around that one), namely cave paintings. The way it affects the real world is inconsistent and tenuous, able to kidnap people and film them but not fight back against its containment procedures.
  • Even Evil Has Standards: In the logs accompanying SCP-1730, which take place in an alternate timeline where the Foundation became much more brutal and cruel after fusing with the Global Occult Coalition, even he is horrified by Dr. Emerson's mass slaughter and torture of humanoid SCPs and the brutal experiments he conducted.
    Bobble: How many, hee hee hee, how many entities were swallowed by Site-13? (laughs) You silly silly out of place boy. Silly little boy. Everything made its way into Site-13. If the Foundation could find it and the Coalition could catch it, it was fed into the meat grinder down here. Everything. They mulched us all, if there was nothing to gain. Some got lucky. Bobble got lucky. Stuffed in a funny box and played with. Toyed with. Experimented with. To see what sounds we made when we wanted to die. Others were not so lucky.
  • Faux Affably Evil: As shown in the episode "Bobble's Back".
    Smile. You're on television!
  • Harmful to Minors: Bobble's show teaches children to become murderers, cannibals and arsonists. Sounds like good, wholesome educational programming.
  • Horsemen of the Apocalypse: He is War in the Competitive Eschatology canon.
  • Immune to Bullets: As shown in Behind the Scenes.
  • It Can Think: At first, the SCP just seems like it's a collection of disturbing cartoons with some supernatural phenomena attached. Then the last two observed episodes reveal that it's aware that the Foundation is blocking its signal. And it's pissed.
  • Knife Nut: At least two episodes feature him carving up victims, one of them a Foundation doctor, with a huge butcher's knife.
  • Magical Clown: Bobble is implied to be an Eldritch Abomination in the guise of an educational cartoon character.
  • Nothing Is Scarier: In the episode "Bobble Hates You", he just stares angrily at the viewer for 30 minutes straight. Also, in "Bobble's Back" he claims that there's... something he wants to do to the parents of his target audience, but refuses to divulge any further information on it.
  • Really 700 Years Old: He apparently introduced mankind to fire and inspired the Navajo legends of skinwalkers. Or so he says.
  • Villainous Breakdown: The last episode comes off as this, lashing against the Foundation that contained him.

SCP-999 - The Tickle Monster

  • All Animals Are Dogs: Acts like a dog, anyway.
  • Anti Anti Christ: According to New Job, 999 is the thing that 231-7 was carrying, and thus a child of the Scarlet King. However, the 7th Bride of the Scarlet King, in contrast to her sisters, gave birth to heroes instead of monsters.
  • Badass Adorable: A friendly, cute little blob of jello that spreads happiness through touch and gets in tickle fights with 682. It even rescues hapless staff and comforts the survivors when 682 makes another murderous rampage-escape attempt.
  • Blob Monster: A rare benevolent example.
  • Cuddle Bug: It likes to hug people with its pseudopods.
  • Good Cannot Comprehend Evil: How does it respond to 682 trying to murder it and escape? It thoroughly enjoyed the experience, and asked for another 'play date.'
  • Fantastic Drug: Touching it induces a drug-like euphoria in people.
  • Friend to All Living Things: It loves all forms of life, including SCP-682! After the two were put into a cell together, 999 requested another encounter, seemingly seeing it as a 'play date'.
  • Friendly Tickle Torture: Its favorite activity, it envelops a person from the neck down and tickles them until asked to stop (though it does not always comply with this request).
  • Nice Guy: Even to 682!
  • Sweet Tooth: Its diet is composed entirely of sweets. M&Ms and wafers are its favourite.
  • Taking the Bullet: SCP-999 loves all animals (including humans) so much that it will leap in front of a person to take a bullet fired at them.
  • Team Pet: Is allowed to wander the site and the staff generally treat it like a well loved family pet.
  • Your Favorite: With scents instead of food. SCP-999 emits a smell that is pleasing to every person who comes into contact with it, but the smell is different for each person. Different people have reported it smelling like chocolate, fresh laundry, bacon, roses, and Play-Doh.
