    600-699 

SCP-600 - "That Guy"

SCP-600 is a humanoid entity with a build approximating an adult man of average weight. The entity is generally featureless, lacking facial features, external ears, nails, body hair, genitalia, and an anus. Full-body scans have shown 600 to has no internal structures of any kind, instead being formed entirely from an unknown material of uniform density close to that of human muscle tissue. It does not eat, breathe, or expel waste, and its age has not been determined. When a human vies 600 directly they will perceive it as a completely normal human that very recollect from the past. It has repeated this ability frequently since containment, referring to itself as a Foundation researcher.
  • 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-601 - Sophocles' Chorus

SCP-601 is a collection of 12 adult humans of varying ages, genders, and ethnicities. The constituent members of 601 perform all actions and bodily functions in unison, and will do so as accurately as is physically and anatomically possible, with no more than 0.15 seconds of delay between any two members of the group. In the event that any of the members expire or become permanently incapacitated for any reason, the remaining members of 601 will enter an agitated state and actively seek out the nearest able-bodied human, which they will transform into a replacement component.

SCP-602 - The Sculptor of SoHo

https://static.tvtropes.org/pmwiki/pub/images/scp_602.jpg
The neighborhood in which 602 resides.
SCP-602 is an unseen entity reminiscent of a poltergeist, which inhabits an apartment in New York City. 602 can manipulate objects within the apartment, and is subject people inside it to attacks, able to exert enough force to knock them down and hold them. Through an unknown method, 602 can apparently transform a living human into a sculpture of variable material, similar to a variety of sculptures already present in the apartment. 602 will destroy or otherwise neutralize any sensory equipment set up within its apartment, and has consistently destroyed concealed surveillance equipment carried by test subjects before transforming them.

SCP-603 - Self-Replicating Computer Program

https://static.tvtropes.org/pmwiki/pub/images/primes_1.png
An output of 603.
SCP-603 is a computer program capable of reproducing and extending its own source code to untold limits. When left to run uninterrupted, 603 will generate prime numbers increasing from 2 and will print them to the environment's standard output. Upon hitting a super-prime, there is a chance that a GPU-accelerated window will open, the contents of which are known to vary in content.

SCP-604 - The Cannibal's Banquet; A Corrupted Ritual

SCP-604 is a set of tableware, consisting of 19 plates of various sizes and designs, and 21 goblets, champagne flutes, and other wineglasses. Whenever an instance of food is placed onto one of these plates, or a liquid is poured into one of the drink vessels, the food will instantly transform into human flesh, or the nearest equivalent organ, body part, or fluid. The Foundation has recently discovered that 604 was crafted by a group of interest who wished to know what human flesh tasted like.
  • Equivalent Exchange: The food and drink transformed by 604 is changed into the closest approximate human anatomy and in direct proportion to the original food and drink. Adding to the difficulty is that transformation is limited to what can fit onto the various plates or within the various drinking vessels, with most of the food being transformed into the equivalent part of an infant. This creates issues for Marshall, Carter, and Dark Ltd. when their attempts to replicate a human head fail for various reasons, the most dramatic of which is when a cake modeled after a head is transformed into a blobby mass of various fatty tissues. They eventually succeed by using some sort of still-living creature that remains unseen until transformation but apparently requires external life support. The resulting human head is alive and sapient enough to voice its disoriented terror in perfect english before being set upon by the assembled diners.
  • More than Mind Control: 604's only anomalous property is its transformation of comestibles; it does not confer any sort of compulsion to transform food and drink nor consume the resulting products, nor any ecstatic reation to same.
  • Pragmatic Villainy: Once MC&D got their hands on 604, rather than sell it themselves, they started auctioning off the opportunity to "safely" engage in cannibalism without the usual legal and moral hassles that comes with consuming human flesh.
  • Religious Horror: 604 was initially found by MC&D in an abbey whose congregation had decided that the "flesh and blood" aspects of communion needed to be more literal, believing the resulting flesh and blood to be that of Jesus himself, and being driven to religious ecstasy by the act of communion complete with hallucinations of Jesus offering his body and quoting scripture and so forth.

SCP-605 - Living Storm Cloud

https://static.tvtropes.org/pmwiki/pub/images/scp605_2.png
605 in an active state.
SCP-605 is a large, amorphous, airborne gaseous entity visually similar to a high-altitude cloud formation. While "active", 605 exhibits behavior similar to that of a predatory organism, and will track ships and aircraft which enter its territory and attempt to engulf them into its body. The "active" state the cloud also causes anomalous disruptions of local magnetic fields, causing compasses and navigation systems to malfunction or report erroneous readings. Due to its ability and its presumed link to multiple disappearances of civilian and military vehicles, the use of unmanned aerial vehicles to "feed" the cloud has been approved to reduce the chances of publicly known incidents.

SCP-606 - "The Teacher"

https://static.tvtropes.org/pmwiki/pub/images/knowledge_scp.jpg
606 manifesting in the woods.
SCP-606 is an orb of light of variable size and intensity. It is presently theorized that 606 is an entity composed of pure knowledge, as it appears to derive sustenance from information, growing in size and luminosity when provided with viable sources of information to its aforementioned maximum size, and shrinking when it is deprived of this source. The mass is sapient, apparently self-aware of all knowledge it has gained over its existence, and capable of intelligent communication. If another sapient individual enters 606's containment cell, it will attempt to "enlighten" them by surrounding the individual's head. This results in generalized epileptic seizures for a period of 30 seconds to 5 minutes, after which the individual lapses into a coma and dies.

SCP-607 - Dorian the Grey Cat

https://static.tvtropes.org/pmwiki/pub/images/grey_cat_floor.jpg
Dorian being listless.
SCP-607 is a grey male American Shorthair cat of indeterminate age with a collar reading "Dorian". Dorian has the anomalous ability to "bond" with one human being in his line of sight at a time. If Dorian dies, the person he has bonded to will die as well. After the bonded person dies, Dorian will proceed to return to life and bond with the next person he looks at. Unfortunately for people who Dorian bonds with, Dorian is suicidal, and will actively put himself into deathly situations, often trying to starve himself to death by refusing to eat.
  • 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

SCP-608 is a length of silver tinsel with a furry appearance. Micro-examination has revealed that the tinsel's appearance comes from a potentially infinite number of progressively smaller 'branches' radiating off of itself. These branches will cause the tinsel to disintegrate any substance that comes into physical contact with it, due to the monofilaments of these branches slicing through the substance at the molecular or atomic level. The process will only cease at the instant the object removed.
  • 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-609 - Dr. Wondertainment's Ontological 6-Balls®

https://static.tvtropes.org/pmwiki/pub/images/platonicsolid.jpg
A single Wondertainment 6-ball.
SCP-609 is a collection of solid green "6" billiard balls in the American pool style, which measure 57.15mm in diameter and are believed to exist only as immaterial manifestations of a concept. Instances of these 6-balls, designated SCP-609-1, are unbound by physical laws. The 6-balls can be manipulated by thought when a sapient creature is in direct visual contact with them. They will emulate the actions the user imagines, including motion, duplication, and instantaneous manifestation at a visualized location. Observers cannot alter the physical appearance of the balls, nor can they erase them from existence.

SCP-610 - The Flesh that Hates

See Characters.SCP Foundation SC Ps 001 To 999.

SCP-611 - Parasitic Toothpick

https://static.tvtropes.org/pmwiki/pub/images/scp_xxx.jpg
A cluster of 611 eggs.
SCP-611 is a previously undiscovered subspecies of botfly. The insects camouflage themselves as common toothpicks, and will attempt to land near or inside a supply of the objects, at which point it will shed its wings and enter a passive state. 611 will lay eggs into the gums of a human subject when used. Hosts of these eggs will notice no signs of invasion until four to seven days later, when the eggs hatch and burrow into the jaw, causing severe discomfort.

SCP-612 - Aggressive Cable

https://static.tvtropes.org/pmwiki/pub/images/2rfefl0.png
A hostile 612 entity.
SCP-612 is an animate, intelligent mass of electrical cables of various types. While in a dormant state, 612 prefers to hide in dark, warm places, where it will be attach itself to an electrical socket. Apart from its sentience and capability for movement, it displays a slightly higher specific electrical resistance than ordinary cables of its type. The mass will not attack unless it is provoked, though it will interpret any attempt to move it as provocation, regardless of intent. If such a movement detaches 612 from its socket, should it be attached to one, it becomes rigid, swaying in the air before lunging at its assailant, suffocating them in the manner of a constrictor.
  • 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-613 - "Wonder Bread!"

SCP-613 is a piece of paper with a recipe for wheat bread and the words "WONDER BREAD RECIPE: PLEASE REFER TO THIS PAPER FOR OPTIMUM RESULTS" written on it. There are at present 10 instances of 613 in Foundation custody, all of them identical in nature. SCP-613-1 are loaves of wheat bread created by following the directions on 613. Instances of 613-1 can vocalize through unknown means, achieve self-locomotion by sliding across and rotating on surfaces, and are capable of sensation and perception of their environment. All instances of 613-1 are fully sapient and have distinct personalities and identities unique from other instances.

SCP-614 - IP Address 57.32.███.███

https://static.tvtropes.org/pmwiki/pub/images/615_1.png
614's main page.
SCP-614 is a website whose homepage is a plainly formatted search page, consisting of a single search box, three drop-down lists, a "Search" button, and an "I'm Feeling Lucky" button. The drop-down lists allow the user to specify a date in a specific range. When a date is entered and the "Search" button is pressed, the website will load a list of search results or "torrents" from various peer-to-peer file-sharing websites at the time of the given date. The "I'm Feeling Lucky" button will return a single random result from a random date. These torrents consist of movies that haven't been released to theaters, strings of code yet to be uploaded to the Internet, and the entirety of the Foundation's current database.

SCP-615 - Stick Blob

https://static.tvtropes.org/pmwiki/pub/images/afro.jpg
615 on the back of a truck.
SCP-615 is a large clump of dead/discarded plant matter that has attained sentience and animation. Despite the lack of organs, a central nervous system, or any other system commonly associated with a fully functioning organic creature, 615 is able to move, manipulate its surroundings, and perform instinctual behaviors independently. In terms of behavior, the clump is no different from any other territorial organism. It will commonly patrol an area of several square miles, and will aggressively attack anything that attempts to intrude into its territory. 615 attacks by completely engulfing its target and contracting its mass, crushing or suffocating them. Eyewitness reports have shown that it is easily capable of crushing objects as large as trucks if it is of sufficient size.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/boeing_737_200.jpg
616, hopefully being safe to approach.
SCP-616 is a prototype Boeing jet. Despite the various alterations, the most important feature of the aircraft is its central left emergency door, which has been dubbed SCP-616-1. While it appears as a standard emergency door, 616-1 is partially covered in extensive markings associated with Satanic cults. The door will autonomously open once every 30 days before beginning to close. This event is considered the activation of 616-1. The speed at which the door closes is highly dependent on 616's altitude and velocity. Failure to properly time the event is catastrophic, since the door closing fully while grounded could affect all life-forms within an unknown radius, posing severe threats to population centers, and requiring immediate use of Procedure 600-Shoki.
  • 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-617 - Pet Rocks

https://static.tvtropes.org/pmwiki/pub/images/zjb0w3.jpg
Three of the entities grouped together.
SCP-617 are entities that resemble large granite rocks, except that each instance possesses a zipper on its side that is fully operational. When unzipped, instances of 617 are shown to possess a mouth with teeth that appear similar in appearance to human teeth. The mouths are fully functional, and can vocalize sounds as well as consume food. The rocks are also capable of limited movement, being able to roll around under their own power. However, 617 also have parasitic tendencies, as well as the ability to influence human behavior. In addition to being able to speak, 617 can generate low frequency sounds that allow them to exert subliminal control over any human that hears it.

SCP-618 - Slim Pickins

See Recap.SCP Foundation Canons under the On Guard 43 folder.

SCP-619 - Lucky Jeans

SCP-619 is a pair of faded jeans manufactured by Levi in 1994, with several stains and tears through apparent use. Whenever a person puts their hand into the pants' right pocket, it will contain two US one-dollar bills and between two to five dimes. In approximately 4% of all attempts to remove currency from the jeans, an activated dye pack will be tied to one of the bills. The explosion, which produces temperatures over 400°C and releases red dye #9, will burn the subject and cause damage to 619.

SCP-620 - Time Keeps on Slipping

https://static.tvtropes.org/pmwiki/pub/images/scp_clock.jpg
The face of 620.
SCP-620 is an analog clock which bears no markings indicating a manufacturer or place of origin. Its face is styled after the yellow "smiley face" design. When 620 is powered, all subjects observing its face experience perceived acceleration of time. The slightest glance will induce the perceived acceleration as quickly as constant observation. After 24 twenty-four continuous hours of exposure, subjects have begun to reject food regardless of hunger, frequently stating that they just ate. Subjects who become aware of how quickly their newfound perceptual effect have become chronically depressed, believing their death to be imminent.

SCP-621 - Hypnobulbs

https://static.tvtropes.org/pmwiki/pub/images/621.jpg
A field of 621 instances.
SCP-621 is a series of highly invasive flowers that have natural bioluminescence. These plants, mainly the Didier’s tulips, are powered by water and other nutrients. The flowers' glow seems to have a hypnotizing effect on humans, with numerous requests by personnel to store them in their offices, all of which have been denied. The effect is also evident in pollinating species, as they are influenced to pollinate 621 instances in lieu of regular plants.
  • 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-622 - Desert in a Can

https://static.tvtropes.org/pmwiki/pub/images/622_3.jpg
A single can of "Desert in a Can".
SCP-622 is a chemical composition under the trade name "Desert in a Can", originally marketed as a security aid for large businesses to incapacitate intruders in a similar vein to tear gas. The directions state that one layer of 622 is to be applied to hallways during a break-in. When applied, 622 becomes odorless and colorless, and all moisture in the immediate area is absorbed by it, creating an easily-cleansable salt-like crust over the applied areas. If 622 is exposed to organic life, dehydration, dried eyes, and profuse sweating, are immediately induced. Other effects include a significant drop in blood pressure, increase in heart rate, dizziness, and chills.

SCP-623 - One Groovy Room

SCP-623 is a room of roughly 7 x 7 x 7m, built in the 1960s by biochemistry professor Dr. H. D., in a prestigious university. Dr. D. was arrested for his activities, but not before his students began making copies of the room. Upon entering 623, personnel have described a feeling of relaxation. 3 minutes after entering the room, personnel are rendered docile, harmless, and incapable of violence, becoming docile and harmless. Exiting the room exhibits inverse withdrawal effects, where observers will feel an intense jolt back to the outside world that becomes significantly stronger over time spent inside. Personnel have reported feeling uneasy, jittery, and slightly paranoid one minute after exiting, escalating to anxiety, fear, and depression.

SCP-624 - "Personal" Music Player

https://static.tvtropes.org/pmwiki/pub/images/scp624drz.jpg
624, playing music generated by Dr. Z████████.
SCP-624 is a Sandisk Sansa MP3 player and voice recorder. When activating 624, a tone will play, which will be picked up through its microphone. If 624 detects the tone from a pair of headphones, the player automatically fills its library with two gigabytes of music, all of which is written, produced, played, and sung by the wearer of the headphones, regardless of their current musical talent. Each song comes with an appropriate album cover and the listener’s factually incorrect profile. The musical tracks are found to continue after the user expires, where they will shift to the sounds of the user's afterlife.

SCP-625 - Anklebiters

SCP-625 are nocturnal organisms composed of distinct sections from no less than seven different species of rodent. The creatures are omnivorous, and have metabolic requirements comparable to those of other rodents their size. When not in a subdued state, instances of 625 are hostile to humans. They will attempt to approach any human subject without the subject noticing, which will result in 625 using its claws to remove a radial slab approximately 3cm in height from both ankles of the subject if successful. The anesthetic produced by the creatures will allow the subject to feel no pain, though it is possible for them to suffer from severe blood loss before becoming aware of their condition.
  • 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-626 - Vision-Altering Sculpture

https://static.tvtropes.org/pmwiki/pub/images/626_4.jpg
SCP-626.
SCP-626 is a metallic structure 72cm in height. When 626 is in the presence of a human being, the subject's vision begins to deteriorating. Intensive examination reveals that the rods and cones within the eye begin to dissipate, rendering the eye unable to differentiate shapes and colors. Seven hours after initial exposure, the subject is unable to detect light through the eyes. Loss of vision occurs whether or not the subject is able to see 626, but it appears to be dependent on the subject's knowledge that the structure is present. Any material that can block visible light will also block the effects of 626.

SCP-627 - Perpetual Circle

https://static.tvtropes.org/pmwiki/pub/images/scp_627.jpg
A group of 627, possibly replicas of the original.
SCP-627 is a sphere composed of unknown stone flecked with blue. When not in close contact with a human being, 627 rolls in a circle approximately one meter across. It will not avoid inanimate obstacles, instead rolling up and over any impediments in its path. It never attempts to go around these impediments, and if contained in a space smaller than one meter, it will increase in speed until it has worn its way out, even to the point where it breaks the speed of sound.

SCP-628 - Flute Copse

https://static.tvtropes.org/pmwiki/pub/images/628.jpg
The limbs of a 628 specimen.
SCP-628 is a copse of 31 large, leafless, hollowed-out American sycamore trees. The copse is a colonial organism, individual trees being linked by massive, hollow stolons. These "runner trunks" connect the base of each trunk to a maximum amount of seven of its neighbors. 628 is capable of isolating any given resonance chamber to play recognizable music. The copse's repertoire includes numerous works composed for pipe organ, as well as a number of previously unknown compositions. The sounds produced by the copse are not anomalous beyond origin. Ordinary infrasound has been shown to cause feelings of fear, awe, sorrow, anxiety, and disorientation. Sound waves which reach 18 Hz, the resonant frequency of the human eye, can also produce optical illusions.
  • 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-629 - Mr. Brass

See Characters.SCP Foundation Misters.

SCP-630 - Black Glacier

https://static.tvtropes.org/pmwiki/pub/images/scpimage1.jpg
A sonar image of the glacier.
SCP-630 is a 130 meter wide underground glacier which, according to surface sonar scans, is moving at an estimated 30m a year. It is composed of what is theorized to be a mixture of water and ice that is opaque black and does not reflect any form of visible light or electromagnetic radiation. When melted, 630 reverts to ordinary, slightly impure water and displays a normal reflection spectrum. Personnel working around the glacier report frequent auditory hallucinations, primarily the sound of someone pleading for help from within the ice. Staff have reported that over a period of time, the hallucinations can create an impulse to make physical contact with 630 that is astoundingly difficult to resist. When direct skin contact is made with the ice, the body ceases to reflect any incoming light, causing it to turn pitch black and be rendered blind, deaf, and mute.
  • 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

SCP-631 is a species of large predatory creature with a vaguely crustacean appearance. They possess winged morphology and a reptilian tail ending in a venomous stinger. The tail also contains the majority of the creature's reproductive systems. 631 instances do not sleep and remain active at night, even demonstrating distress or panic in response to low light environments. The reaction rises in intensity over time, and can only be alleviated by immediate feeding or exposure to daylight. The creatures will subsequently locate the nearest isolated sleeping human and impale their throat with its stinger (preventing any vocal reaction). Following injection of its paralytic venom, 631 will remain in this position for 2-3 min while the victim expires. It will then consume the victim's internal organs, replacing them with fertilized eggs produced via its tail.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/spodernew.jpg
A mature instance of 632.
SCP-632 is a species of spider that reproduces via unconventional means. While the exoskeleton is composed of a substance resembling calcified fat, the interior is almost entirely derived from human brain tissue. 632 reproduces by exposing a human host to an array of sensory triggers, including the visual patterns on the abdomen, the tactile sensation produced by instances crawling on human skin, and several as-yet-unidentified chemical compounds released by mature instances. Hours after exposure to all of 632's sensory triggers, affected individuals will experience mild headaches, the sensation of spider silk on their skin, and repeated intrusive thoughts about spiders. MRI scans reveal the presence of hundreds of small filament-like structures measuring 2-3cm in length forming in the frontal cortex of infected individuals' brains, from which juvenile instances emerge. The headaches will worsen to the point where the subject caves in their skull in an attempt to ease the pain, the spiders pouring out from the newly formed wound.
  • 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 their skin. It will then cause intrusive thoughts of spiders and grow filaments of baby spiders 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 adult SCP-632 spiders are released.

SCP-633 - Ghost In The Machine

https://static.tvtropes.org/pmwiki/pub/images/633.png
The Ghost introducing itself.
SCP-633 is a self-aware computer virus that identifies as "The Ghost". The Ghost also appears to have supernatural origins, as the computer it was discovered infecting on retrieval appeared to be discolored by what appeared to be ectoplasmic residue. Any device that has interfaced with The Ghost will permanently become a vector for infection, down to the constituent components. Living matter which comes into physical or near-physical contact can also become affected. The Ghost demonstrates itself as an inquisitive being, fond of taking to people who log onto a computer terminal that it has currently infected to ask them questions about their lives. Although The Ghost is not believed to be malevolent at this time, it has demonstrated the capability to effortlessly seize control of an entire Foundation Site's computer network, without regard for security clearance or similar restrictions.
  • 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-634 - Forgetful Goldfish

https://static.tvtropes.org/pmwiki/pub/images/goldfish_8.jpg
634 in a fishbowl.
SCP-634 is a male goldfish of full maturity. 634 drastically affects the short-term memory and attention span of all living creatures in close proximity to it (referencing the myth of its species having a 3-second memory span). The only noticeable anatomical difference between 634 and a common goldfish is that its mouth holds a row of sharp teeth. The fish's bite has a coagulating effect, which minimizes blood loss and causes a burning sensation at the point of incision.

SCP-635 - Medieval Bootstrap Program

https://static.tvtropes.org/pmwiki/pub/images/book_49.jpg
The manuscripts of 635.
SCP-635 is a set of illuminated manuscripts dating from the 13th Century. These scripts are written in a combination of Latin and a previously unknown script that relies on numerical and logical elements, similar to that of a modern computer programming language. If a subject with a rudimentary understanding of Latin begins reading volume one 635, they will experience a growing reluctance to discontinue doing so proportional to their general intelligence, reading comprehension, problem-solving aptitude, and mathematical ability. If the subject is allowed to continue reading, they will finish the first few volumes in approximately 12 hours, after which they will enter a fugue state where they will immediately search for tools and material to start construction of an instance of SCP-635-2, a robot with varying degrees of manipulation and data storage. The design and materials used in the construction of these robots will vary based on the aptitude of the subject and materials and tools available. 635-2 instances will always be built with a method to input the text of a single volume of 635. The subject will continue to construct more and more robots to the best of their ability, until succumbing to exhaustion.

SCP-636 - Elevator to Nowhere

SCP-636 is a maintenance elevator in a hotel. Unlike the other elevators in the building, 636 contains a magnetic card reader which, when used with a specific card key, will cause the elevator to move to a third sub-basement beneath the building. According to the building plan, there are only two sub-basements beneath the hotel, and the owner was not aware of an elevator with magnetic card access. Whenever any individual attempts to access this floor via 636, the elevator appears to work normally. However, upon reaching the non-existent floor, the elevator (as well as personnel or remote monitoring equipment within it) will disappear.

SCP-637 - Viral Cat

SCP-637 is a black cat with latent psychic abilities. 637 lives entirely inside the mind of a human host, thereby designated SCP-637-2. The current 637-2 instance is a 65-year-old Caucasian woman who calls herself “Margie”. As 637's host, Margie spends much of her time in a semi-catatonic state, with only occasional lapses of lucidity. She has also described 637 as "a skinny fellow, real easy-going”, not seeming to find any troubles with her life as its host. Although 637 normally resides in a “blank space” in its host mind, it is capable of appearing for several minutes as a drawn item on paper, wood, or other substance. If a sapient organism not previously carrying 637 sees the reproduction, the image will vanish, and 637 will take up residence in the new subject’s mind.

SCP-638 - The 1914 Chicago Federal Reserve Heist

https://static.tvtropes.org/pmwiki/pub/images/chappellheader.png
Richard Chappell, the man who put the Pulaski Crew together, in 1904.
SCP-638 were the "Pulaski Crew", a criminal gang active during the 1910s. The Pulaski Crew was comprised of five individuals, each capable of a unique anomalous ability, designated SCP-638-A through -E. 638-A, "Louis "Bagel" Bernstein"; 31, was a Jewish-American with the ability to produce and manipulate fire. 638-B was ""Mads" Moody"; 38, an American who wielded amounts of strength no other human could possess. 638-C was "Guiseppe "Permontto" Fiori"; 34, an Italian-American who possessed an anomalously powerful ability of persuasion. 638-D and -E were "Ah Num" and "Ah Tom"; 41, a pair of Chinese twin brothers who were proven to be powerful thaumaturges. Chicago Spirit boss Richard Chappell organized the Crew and led their only major heist in 1914, wherein they used their anomalous abilities to perpetrate a robbery of the Federal Reserve Bank of Chicago. Over the course of nineteen minutes, the Pulaski Crew were able to eliminate security, take hostages, and gain access to the vault, where they stole 2,000 tons of gold bullion meant for a classified government handoff. The entirety of the Pulaski Crew have since died.

SCP-639 - Distorted Man

SCP-639 is a Caucasian man, age 24, who is viewed simultaneously from all angles, regardless of a viewer's position. Standing in front of him will have a view of his front, back, sides, and so forth. Attempts to capture 639 through any sort of photographic medium yields a heavily distorted figure. Exposure to 639 causes extreme eyestrain and mild paranoia. 639 is himself affected by his anomalous property, as seeing things from every angle at once has rendered him mentally unstable.

SCP-640 - Lucent Beams

https://static.tvtropes.org/pmwiki/pub/images/scp_640_large.jpg
Wounds afflicted by 640.
SCP-640 is a sentient, free-roaming electromagnetic phenomenon, typically manifesting as several circular spots of yellow-orange light measuring between 18 and 57mm in diameter, depending on the entity's appetite and energy level. In all known instances, 640 has disguised itself as areas of sunlight shining on a wall, typically inside a child's room. 640 is carnivorous, and is capable of deriving sustenance from all known Earth animals, though it shows a marked preference for human children. It consumes prey by inflicting burns of varying severity and depth, tending to target the face, legs, and forearms of its prey for unknown reasons.

SCP-641 - The Pacifier

https://static.tvtropes.org/pmwiki/pub/images/eggdoll_7.jpg
641 after 45 minutes of disassembling.
SCP-641 is a set of Russian matryoshka dolls, each layer being improbably thin. 1,347 total layers of the dolls were measured and demonstrated a mean thickness of .04 micrometers, with a standard deviation of .02 micrometers. If the disassembled dolls are left untouched for a length of time ranging from five to seven minutes, they will animate and begin to reassemble, the largest doll "leaping" over the next largest until the doll is assembled at an extremely rapid rate. Subjects disassembling 641 show an aversion to leaving the dolls alone, and if compelled to do so will become angry, physically fighting any restraints until the dolls begin to reassemble.

SCP-642 - Hot Springs

https://static.tvtropes.org/pmwiki/pub/images/6421.png
Water flowing into 642-1.
SCP-642 is a pair of geothermal hot springs (SCP-642-1 and SCP-642-2) located in northern Iceland. Characterized by extremely high flow rate, water emerges at both springs at temperatures varying between 45 and 57°C depending on the time of year. Immersion of a sexually mature female mammal in 642-1's waters induces fusion of two unfertilized ova or polar bodies present in pre-ovulatory follicles, producing a diploid zygote genetically identical to its parent. The chemical and biological properties of 642-1 result in rapid development of the zygote, usually at a rate two to four times faster than normal for the species. 642-2 induces the opposite effect in mature females, all cellular development of a developing zygote ceases as the cells disintegrate, resulting in the death and expulsion of the embryo.

SCP-643 - Delicious Chocolates

See Recap.SCP Foundation Canons under the From 120's Archive folder.

SCP-644 - Mr. Hot

See Characters.SCP Foundation Misters.

SCP-645 - Mouth of Truth

SCP-645 is a large Pavonazzetto marble disk with a humanoid face carved into it, similar to the famous Bocca della Verità carving in the Santa Maria church of Rome. As with the Bocca carving, the mouth and eyes are empty holes. But unlike with the Bocca carving, subjects who place their hands inside 645's mouth describe it as warm and moist. 645 embodies, and has been hypothesized to be the origin of, the lie-detecting properties attributed to the Bocca carving. Any subject lies while their hand is within the carving's mouth will activate the carving, which will then bite the subject's hand off at the wrist and swallow it.

SCP-646 - Birth Worm

https://static.tvtropes.org/pmwiki/pub/images/646_sweat.jpg
Viscous "sweat" accumulated from 646.
SCP-646 is a large, bloated, translucent grey creature measuring roughly 5.6 meters in length and weighing between 3400 and 3700kg. At one end of its body is the approximation of a torso, with a prominent ribcage and a wide, rounded head. Seven sets of three-jointed limbs are located evenly spaced down the front of the body, a long series of udder-like organs are located between them. The body tapers to a blunt point with an orifice reminiscent of a cloaca, and the entire frame heaves and shudders irregularly. The shadows of various internal organs can be seen through 646's flesh, which is smooth and malleable, and constantly produces a clear, harmless mucus. The creature is in a constant state of giving birth to infant instances of humans and animals, including those who have become extinct.

SCP-647 - Hungry Box

SCP-647 is a cardboard box appropriately sized for a CRT television. When a live human being is within 1.5 meters of the object, 647 will change its dimensions so the subject can fit inside it easily. When a subject enters the box, its flaps will close and become unable to be opened. Once the flaps close, 647 will secrete a digestive fluid that is absorbed by the subject's skin, dissolving tissues from the inside out. Once the subject is completely dissolved, the liquids are absorbed by 647, and undissolved elements are forcibly expelled. The box is also known to produce food, alcohol, and blankets to lure prey if it is left unfed.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/scp648.jpg
A path within the hedge maze.
SCP-648 is a hidden entrance located inside a hedge maze. Although no official record of 648 exists, evidence suggests that the entrance was incorporated into the maze shortly after its construction. When subjects enter the maze via 648, they are displaced to what appears to be an extradimensional space separate from the real maze. Exploration teams have encountered living creatures within the maze at distances greater than 2 kilometers from the entrance. These creatures have proven to be extremely dangerous, and as such, should be avoided if at all possible.
  • 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-649 - Matchbox Full of Winter

https://static.tvtropes.org/pmwiki/pub/images/medium_08.jpg
The matches within 649.
SCP-649 is a matchbox from an unidentified brand, with a thirty-two match count. The underside of the box is marked with a logo in the shape of a snowflake that feels cold to the touch. Whenever a match from 649 is struck, snow will shoot out in contrast to the sparks of a normal match. Once struck, the head (which is blue rather than red) will show visible crystallization and the main anomalous properties of 649 will manifest. Silhouetted figures can be seen in the resulting snowstorm.

SCP-650 - Startling Statue

SCP-650 is a black statue of a stylized humanoid standing 167cm tall. The statue does not possess hands or facial features, as the limbs taper off into rounded points and the head is a smooth surface all around. The default posture of the statue while under direct observation has the statue reaching upwards, with its head tilted as if facing the sky. Much like SCP-173, 650 can relocate itself when it is not being observed. The statue's chosen relocation point will be behind whomever is in its containment site, where it will assume a threatening posture. No noise is made during this process. The relocation point and the statue's posture are typically close enough to induce an automatic fight-or-flight response in the observer once they turn around and see it.

SCP-651 - Tissue-fusing virus

SCP-651 is a highly contagious virus that primarily infects humans, causing the fusion of soft tissues. The effects of 651 can be observed early in the form of webbing of the fingers and toes. The virus spreads to affect the entire body, typically fusing the subject's thighs and cubital fossa, and eventually causing all orifices to seal completely. Subjects surviving into the late stages of 651 are forced into a fetal position, the forehead eventually fusing with the knees.

SCP-652 - Meteorological Dog

https://static.tvtropes.org/pmwiki/pub/images/scp_652.jpg
652 relaxing in a front yard.
SCP-652 is a male Basset Hound that appears to be physically normal beyond four significant abnormalities. The dog has a tattoo on its stomach in the shape of the Marshall, Carter and Dark logo, x-rays reveal several poorly-healed skull fractures and broken ribs. Its jaw muscles are well-developed, above that of a normal dog of its breed. The larynx is grossly distorted, showing significant diversion from the expected size and shape. It is unclear whether this is the result of genetic engineering or surgery. 652's behavioral anomaly is the ability to produce human speech instead of barking, or other standard canine vocalizations. The dog's voice has it constantly making meteorological predictions for various locations around the world. These predictions have been found to be 100% accurate for all locations able to be identified.

SCP-653 - The Boomerang

https://static.tvtropes.org/pmwiki/pub/images/boomerang_2.jpg
The boomerang stuck in the ground.
SCP-653 is a plastic, multi-colored boomerang measuring 25cm from tip to tip. If a person makes skin contact with the item, they will instantly become obsessed with it, never allowing it to leave their possession. After 48 hours, they will develop a condition similar to magnetoception, becoming aware of 653’s approximate position at all times. Once the subject is aware of where the boomerang is, they will be compelled to throw it as they would a typical boomerang. Instead of returning, 653 will travel large distances away from the subject. Once 653 has been thrown, the subject will immediately begin seeking it out. The subject will invariably be able to locate it with the aid of their magnetoception.

SCP-654 - Thunderhorn

See Recap.SCP Foundation Canons under the folder The Trashfire.

SCP-655 - Biological Disinformation Campaign

SCP-655 is an 18 x 20 x 4m windowless structure within a network of buildings located in the Democratic Republic of the Congo. At random intervals, which have been observed to be between a range of 2 months to 11 years, a random animal will spontaneously manifest within 655. These animals, collectively known as SCP-655-A, will each feature radically different biological and/or behavioral traits than those of their original species.

SCP-656 - Home Edition

SCP-656 appears to be a board game titled "████ ██████ Home Edition”, presumably the name of a mid 1980's game show. Contained inside 656 is a recordable VHS tape (SCP-656-1). When inserted into a VCR attached to a television, the tape plays a recorded episode of the show, which appears to follow a quiz show format wherein three contestants answer trivia questions to win money. All contestants are confirmed to be alive, although none of their have suggested that they competed on a game show.

SCP-657 - Death-predicting Man

https://static.tvtropes.org/pmwiki/pub/images/657_1.jpg
657 in a field of wheat.
SCP-657 appears to be a Caucasian man 55 years of age. 657 is mostly bald, with a small amount of gray hair remaining. He prefers to be addressed as "Gustav" or "Mr. Nobel", but will also respond to his SCP designation. 657 displays the ability to predict the time of a person's death with extreme accuracy. In order to make one of his predictions, 657 requires physical contact with the individual. The contact need not be prolonged or invasive, as a simple handshake is sufficient. To date, all of 657's predictions have proven accurate, though 657 claims to be unable to determine any information as to the cause or circumstances of an individual's death.

SCP-658 - "Botflies"

https://static.tvtropes.org/pmwiki/pub/images/658.jpg
An instance of 658.
SCP-658 are autonomous robotic devices resembling insects. The bottom half of each specimen contains four spiderlike, highly flexible legs and a single "eye". The appearance and structure of the upper half is different in every 658 specimen, as well as size and weight. 658 instances remain active at all times, despite appearing to lack any viable power source. While the instances' behavior varies between them, when otherwise unoccupied, they tend to explore their surroundings. 658 are capable of running at varying speeds, climbing flat vertical walls, and swimming. 658 are also capable of reproduction, achieved through "impregnating" other machines. Embryos of developing instances gradually break down the host's body in preparation for birth.

SCP-659 - Communal Avian Intelligence

https://static.tvtropes.org/pmwiki/pub/images/scp_heron.jpg
A single instance of 659.
SCP-659 is a species of heron which displays modular intelligence that increases when surrounded by more of its kind. 659 is known to be able to subsist on any form of meat, although it will still consume fish whenever possible. 659's intelligence allows it to perform tasks that most species of bird could not accomplish. Even an isolated instance of 659 can solve simple problems, use tools, and learn extremely quickly. When in a group, 659 is capable of escaping all forms of containment the Foundation has attempted to utilize. For this reason, the only effective containment strategy is to keep all 659 instances isolated.

SCP-660 - Earthen Womb

https://static.tvtropes.org/pmwiki/pub/images/urn_2.jpg
SCP-660.
SCP-660 is an irregular earthenware urn 23cm in height and 28cm in diameter, with an opening 20cm in diameter. The interior of the urn is coated with dried mammalian uterine tissue, similar to human endometrial lining. 660 is capable of indefinitely preserving all biological tissue placed inside it, regardless of external conditions or the state of the sample, until the tissues are removed. Living tissue will remain viable, and entire living organisms will remain alive, even when deprived of sustenance for extended periods of time.

SCP-661 - Salesman, Too Good to Be True

https://static.tvtropes.org/pmwiki/pub/images/rivkin.jpg
661 before his capture.
SCP-661 is an overweight Caucasian man who has found via psychological assessment to carry an abrasive attitude and a poor temper, which have increasingly worsened since his containment. Testing has determined that 661’s voice has the ability to manipulate others into wanting what he tells them to want. Test subjects have described the effect as feeling like a continuous weak compulsion, which remains in the back of their mind for up to a week after encountering 661.
  • 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).

SCP-662 - Butler's Hand Bell

See Characters.SCP Foundation SC Ps 001 To 999.

SCP-663 - Living Water Filter

SCP-663 is a water filtration pitcher that appears capable of filtering any water-bearing solution into clean and drinkable water. Any water produced by 663 is near-completely deionized and lacks any distinctive taste. While is in the process of filtering, the sound of a faint heartbeat can be heard emanating from 663's filter core. A distressed human voice will also emanate from the pitcher. Depending on duration of when the pitcher is filled and the amount it is filled to, the voice will either beg for water and act parched, or will beg for the water to cease and act as though it is drowning.

SCP-664 - The Floor to Nowhere

https://static.tvtropes.org/pmwiki/pub/images/664.jpg
A hallway affected by 664.
SCP-664 is an anomaly contained to the third floor of a high school in Pennsylvania, USA. Living biological organisms crossing the approximate outer edge of 664 are invariably subjected to spontaneous disappearance shortly after full immersion into 664's area of effect. SCP-664-1 is the collective term for living biological organisms that re-emerge from 664. To date, 67% of organisms entering 664 have subsequently returned. Returning instances of 664-1 have thus far been unable to provide descriptions of their experience during their period of absence.

SCP-665 - The Garbage Man

https://static.tvtropes.org/pmwiki/pub/images/scp_665.png
665 shrouded by his fused mass.
SCP-665 is a man whose external appearance changes frequently. Any non-living solid object with a mass less than that of 665 that comes in contact with his body instantly fuses to it. Within one hour, the object will effectively become part of 665’s body, and will affect smaller objects in the same manner. It is worth noting that this means 665's mass increases with each item added, so all personnel are advised against adding any further objects.

SCP-666 - Spirit Lodge

https://static.tvtropes.org/pmwiki/pub/images/scp_666.jpg
A young man inside 666.
SCP-666 is a medium-sized Tibetan yurt made of tied wooden branches and covered in yak leather. Periodically, the yurt will change its location within its area of confinement, though it has not made any attempt to escape confinement to date. When an individual with no history of significant addiction enters the yurt, it remains dormant and seems to have no ill effects. Individuals who have a history of substance abuse, however, will experience a hallucinogenic effect when inside the structure. During these hallucinations, subjects report that they are confronted by SCP-666-1, an individual who will indulge the subject in their preferred vice. As time progresses, the subject is encouraged to indulge further while simultaneously being encouraged to stop. Should the subject show remorse or a strong desire to give up their addiction, 666-1 will slowly adopt a more genuinely friendly tone. If the subject gives in to 666-1's temptations, however, the entity becomes increasingly hostile.

SCP-667 - Fairy Kudzu

https://static.tvtropes.org/pmwiki/pub/images/kudzu.jpg
A landscape overrun with 667.
SCP-667 consists of a colony of flowering vines of an unclassified species morphologically similar to "kudzu", designated SCP-667-1, engaged in a symbiotic pairing with an unclassified species of flying creature possessing insectoid and humanoid morphological qualities, designated SCP-667-2. In the presence of adequate nutrition, 667-1 is capable of growing at a rate considerably greater than that of the standard kudzu plant. The vines' primary source of nutrition is derived from humans and large mammals; upon encountering a sleeping, paralyzed, or dead mammal within its radius, 667-1 will rapidly grow around and through the creature, gradually consuming and metabolizing its remains to further its growth. Should the growth begin to slow, swarms of several hundred 667-2 instances separate from the main colony and will travel outward until encountering any mammal in the area. All human beings directly observing a 667-2 swarm have described a strong hypnotic effect and a compulsion to follow it. Upon reaching the edge of 667-1, the mesmerized individual will sit or stand still and continue to observe the swarm until dying of thirst, exposure, or being engulfed by 667-1.

SCP-668 - 13" Chef's Knife

https://static.tvtropes.org/pmwiki/pub/images/oldchefsknife2fc3.jpg
SCP-668.
SCP-668 is a 13 inch chef's knife with a rosewood handle and full-tang construction, crafted at some point from the late 1930s. When carried by a human with violent intent towards another human, the knife broadcasts a psychic signal that renders all sentient beings with a Psionic Resistance Index of 97 or lower incapable of assisting the victim nor is the victim capable of defending themselves against their attacker. Affected subjects report a sudden sense of apathy while under 668's influence.

SCP-669 - A Didactic Perspective

https://static.tvtropes.org/pmwiki/pub/images/ball_5.jpg
669, recently unearthed.
SCP-669 is a sphere which resembles a large ball bearing. 669 activates when placed within 54cm of any object larger than itself, and is set into motion. While active, 669 appears to lack gravitational, instead establishing an orbit around the object at a set of distances up to 54cm from the object's surface. Collisions with an object larger than itself cause 669 to relocate into a new orbit around the colliding object. Pushing 669 into an orbit closer to an object it orbits requires a force of approximately 50N, and is accompanied by a brief photoemission of seemingly random frequency from 669's surface.

SCP-670 - Family of Cotton

SCP-670 is comprised of four roughly humanoid individuals, SCP-670-1, SCP-670-2, SCP-670-3, and SCP-670-4, who refer to themselves collectively as "the Cotton Family". The members of 670 possess a thin outer layer of hardened clay "skin", showing signs of deterioration from over long lengths of time. Under this, the flesh, organs, and nervous system are composed entirely of different types of thread. The majority of the thread is cotton, but large amounts of silk and polyester are also present. Small amounts of rayon and nylon are also noted in the internal organs. The skeleton is composed of rope knotted into a suitable shape, and the fingers seem to be rusted sewing needles.

SCP-671 - Deconstructing Ants

https://static.tvtropes.org/pmwiki/pub/images/camponotus671.jpg
The queen of 671, along with a handful of workers.
SCP-671 is a colony of Spanish carpenter ants comprising 30,000 individuals. The ants appear attracted to artificial devices as to food sources. When they are faced with a complex artificial device, individual ants will attempt to reduce the device to its simplest components. In the process, even a single 671 instance is able to exert forces several hundred times greater than a normal ant of its species. When large numbers of the ants collaborate, they are capable of surprising feats.

SCP-672 - Rock Coral

https://static.tvtropes.org/pmwiki/pub/images/rock_coral_1.jpg
672 growing on a desert bluff.
SCP-672 is a species of coral that grows primarily in a desert environment. When not active, 672 polyps completely seal themselves within their shells and become nearly impossible to distinguish from desert rock formations. The coral only poses a real threat during expansion, in which the colony attempts to draw in as much prey as possible leading up to reproduction. 672 will begin emitting a pheromone that has been demonstrated to create a desire in vertebrates to move towards its source. Victims attempt to make as much skin contact as possible once they reach 672, allowing it to feed upon them with maximum efficiency.

SCP-673 - Tissues

https://static.tvtropes.org/pmwiki/pub/images/david_cerny_embryo.jpg
A portion of 673 resembling a human embryo.
SCP-673 is a mass of organic tissues connected in a seemingly random assembly. These tissues include recognizable structures such as hearts, digestive tracts, blood vessels, and brain matter. These tissue structures are also noted for their increased size, appearing 20 to 50 times as large as their normal counterparts. The tissues appear to operate without the need for any external stimulation or substance, with hearts beating for days with no blood or nerve connections, and lungs continuing to expand and deflate even when severed and fully submerged.

SCP-674 - The Exposition Gun

SCP-674 is a "Zapper" light gun peripheral for the Nintendo Entertainment System, consistent with other models that were bundled with the console in North America after 1985. When 674 is pointed and fired at any video screen, the user perceives that he or she has fired a shot into the displayed scene. Any physical object contained within the scene, whether live or previously recorded, will react appropriately. People who are shot onscreen will appear to die or be wounded, and other people in the scene will duck, take cover or flee off camera. In worst case scenarios, recorded persons have been known to return fire, killing 674's wielder in the process.
  • 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 Cameo: A blip on the entry notes that the inventor of the gun became aware of the Foundation when he tried to shoot a redacted television character that's clearly Yakko Warner, during the "Nations of the World" song. Yakko responds by mocking him about how the Foundation is going to get him before going on like nothing happened.
  • The Dog Bites Back: One of the doctors testing SCP-674 met his end when he made the mistake of choosing the cast of Star Trek as his target; not only did the show's plot logic prevent him from fatally wounding Kirk, but the characters then proceeded to use Techno Babble to fire a shot back at the doctor, killing him.
  • 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.
  • Plot Armor: This is apparently still in effect, despite 674's otherwise typically fatal results; in the aforementioned Star Trek incident, the shooter found that, even when aiming directly at Captain Kirk, he could only score non-fatal shots on him, despite being able to off security officers with no trouble.
  • 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.
  • Toon Physics: Firing SCP-674 at a cartoon character produces unpredictable results. They may regenerate and scold the shooter, end up covered in ash with an Ash Face, or [DATA EXPUNGED].

SCP-675 - Shadows Through the Window

SCP-675 is a window and frame found in the living room area of the northwest portion of Observation Post 9010. At random intervals, shadows resembling humanoid figures (designated as SCP-675-1) can be seen through the window. These shadows are visible at all times of day and night, and are seen to be visually distinct from normal nighttime darkness. 675-1 instances often tap on the glass of 675 and converse with one another, along with various other benign actions. 675's secondary anomalous effect is a hallucinogenic effect manifesting in individuals who remain in Observation Post 9010 longer than 45 days. Subjects become convinced of the malevolent nature of 675-1 instances. The longer that subjects are exposed to 675, the more extreme these hallucinations become.

SCP-676 - Unnatural Hot Spring

https://static.tvtropes.org/pmwiki/pub/images/canyonspring.jpg
The spring nestled in its canyon home.
SCP-676 is a hot spring connected to a 7km stream where water flows uphill to the basin. Small items and organisms caught in the stream are continuously deposited and dissolved in the hot spring. While the reason for this is not known, all materials introduced to the spring will fall apart immediately, dissolving completely within a few seconds. Probing 676 through optical and sonic methods have mapped it extending deep underground, but have not located a destination point. Analysis of the data indicates that the surrounding bedrock is abnormally soft, which may be related to the high incidence of localized earthquakes in the area, and the periodic shifting of 676's subterranean channels.

SCP-677 - Unpredictable Pogo Stick

https://static.tvtropes.org/pmwiki/pub/images/677.jpg
677 before it was lost
SCP-677 is a silver pogo stick that has significantly visible wear and tear. Etched onto the side is an engraving reading "For Mike: Happy Travels!" The pogo stick's frame also appears to be indestructible by all normal means. When used, 677 will immediately jump to unpredictable heights and speeds, regardless of the degree of power applied to the jump. The pogo stick is forbidden to be used for purposes other than testing, as its last usage landed it in the vicinity of Saturn's orbit.

SCP-678 - Trauma Harvester

SCP-678 is a statuette of a sleeping angel that displays no unusual characteristics under visual inspection. Upon making unshielded physical contact with it, 678 excises highly traumatic events from the subject's memory, leaving a blank period in the subject's recollections of the past. The object's function is currently being evaluated for use as an amnestic, but the further effects of 678 render it unsuitable for use at this time.

SCP-679 - Eyerot

https://static.tvtropes.org/pmwiki/pub/images/scpeyes.png
An unfortunate victim of 679.
SCP-679 is a fungal infection of a previously unknown species. It is highly contagious through direct contact with the fungus, though other means of transmission have not been ruled out. In early stages, subjects report seeing tiny, bright dots moving rapidly within their field of vision. This is especially prevalent when sneezing or looking into strong blue light. One week after initial exposure, the sclera turns black and the subject loses vision at this time, becoming entirely blind. During this stage of infection, small ulcerations appear in the corners of the eyes, causing the vitreous humor to begin leaking out, giving the appearance of thick black tears Mycelia are also pushed through these ulcerations as the eye begins to rot entirely, a process accelerated by the fungus. By the time the eyes have gone entirely, the sockets are filled solely with the fungus, with a thick mass of mycelia hanging from the empty sockets.

SCP-680 - Clockwork Skull

https://static.tvtropes.org/pmwiki/pub/images/skulldevice.jpg
680 on its creator's desk.
SCP-680 is a slate sculpture taking the form of a human skull missing the mandible. The skull’s orifices have been filled with a presently-unknown black substance. Beyond its improbably high durability, the skull itself appears to possess no particularly unusual properties. Resting atop the skull is SCP-680-2, a set of mineral appraisal tools connected to a large eyepiece, which itself is connected to a bronze head strap. Whenever a mechanical item of sufficient complexity is placed approximately 0.5 meters in front of the completely assembled 680, several of the tools on 680-2 begin to move of their own accord, setting themselves to a unique setting seemingly "tuned" to the object in question.

SCP-681 - Hostile Helium

https://static.tvtropes.org/pmwiki/pub/images/scp_681_1.jpg
Numerous tanks filled with 681.
SCP-681 is a collection of two hundred 155cm canisters filled with an apparently sentient form of helium gas with unusual properties. In the event that a cannister leaks, the helium will escape and move to the vicinity of brainwave producing organisms, filling the airways and sinus cavities with itself. If the helium gathers in a large enough volume of concentration, this process can lead to death via suffocation.

SCP-682 - Hard-to-Destroy Reptile

See Characters.SCP Foundation SC Ps 001 To 999.

SCP-683 - Refrigerator Art

https://static.tvtropes.org/pmwiki/pub/images/683art.jpg
SCP-683-2.
SCP-683 consists of two combined components. SCP-683-1 is a white 1953 Crosley Shelvador brand refrigerator showing moderate external wear. SCP-683-2 is a child's drawing on standard 8.5" x 11" white paper, oriented as a landscape, and affixed by unknown means to the refrigerator's exterior. Any person either uttering disparaging remarks about the drawing or attempting to remove it from the surface of 683-1 will incur damage to their internal organs and skin/musculature upon ingesting food. This damage manifests as the excision of tissue from various locations of the body equal in mass to the food ingested. The effect ceases once the victim has ingested .42 kilograms worth of food and an equal amount of tissue has been excised. All subjects have expired within 26 days of the last excision. Once excision of tissue is complete, a brown paper bag containing the excised tissue (hereafter SCP-683-3 )will appear in the interior of 683-1. 683-3 instances has consistently been labeled with the name "Eric".

SCP-684 - The Caretaken

https://static.tvtropes.org/pmwiki/pub/images/motherofpearls.jpg
An underwater photograph of 684.
SCP-684 is a massive object found on the seafloor of the Indian Ocean, assumed to be a living creature. The outward "skin" of 684 is dark brown, with a rough, grainy texture. There is a slight "give" when pressure is applied to its surface. From time to time, small sections of 684's surface will dimly glow a faint blue, yellow, or pink light. These lights tend to move in the direction of 684's central mass, or to six slowly-pulsating sphincters that are believed to be analogues for mouths.

SCP-685 - Non-Bottomless Pit

SCP-685 is a large hole located in a remote mountain region. Roughly once every 2-5 hours, objects are observed rising out of the hole, pausing at a height of ±2m relative to the rim of the hole before descending back into it, in a cycle that increases the velocity of the object for every descent. Human exploration of 685 has been limited to the lighted portion of the hole to reduce the incidence of injuries from collisions with objects emerging from the pit.

SCP-686 - Infectious Lactation

https://static.tvtropes.org/pmwiki/pub/images/milk_bottle_1.jpg
A bottle of 686.
SCP-686 is an opaque white liquid consisting of a suspension of lipids and proteins that is indistinguishable from ordinary dairy milk. The infection, beginning and gradually continuing upon consumption, increases the host's lactation rate regardless of gender, commencing lactation if the subject is male. The infection can be treated by milking infectees on a daily basis. Neglecting to perform this process will render the subject's torso an enormous udder, with the subject's mental state being reduced to that of a docile animal.

SCP-687 - NOIR

https://static.tvtropes.org/pmwiki/pub/images/disk_1.jpg
The floppy disk that holds NOIR.
SCP-687 is a Commodore 64 home computer with a 1541 5.25” Disk Drive (SCP-687-2) built the same year as the computer installed into it. When 687-2 is connected to computer, SCP-687-3, a 5.25” floppy disk without manufacturer’s markings, can be loaded into the drive and read like any normal disk. Only one file, "NOIR" is visible to the operating system. NOIR appears to be a text-based adventure game where the player’s in-game avatar always matches the appearance and dress the player has when starting the game. This avatar will also possess whatever objects or equipment the player has on their person when starting the game. After a play session, the next time the player enters REM sleep, they will have an unusually vivid dream where they experience the events that had occurred during the game. The player’s perceptions are indistinguishable from reality during the dream, extreme cases resulting in physical manifestations of injuries suffered within it.

SCP-688 - Hole Dwellers

https://static.tvtropes.org/pmwiki/pub/images/log.jpg
688 barely visible inside a log.
SCP-688 is an animate and apparently living entity that shares many morphological similarities with the Chestnut Lamprey. 688 does differ in several key respects, specifically having no external sensory organs, gills, or cloacal openings. 688 is also much larger and varies considerably more in size, ranging from 10cm to over 200cm in length. The entity is an ambush predator, inhabiting a nesting site that conceals its body from the light and anchoring its mouth to an external opening. While in the site, 688 does not move and will consume all biological matter that enters the opening.

SCP-689 - Haunter in the Dark

SCP-689 is one of the most dangerous anomalies in Foundation custody. It's a small green soapstone statue, 30cm in height, carved in the semblance of what appears to be a deity of the underworld; a skeletal figure seated on a throne with its hands clasped over its knees. 689 is completely inert as long as it is being watched by at least one human being. Behaviors such as blinking do not appear to interrupt the "watching" for this purpose, but any lapse in attention renders the observer vulnerable. Should 689 remain unobserved for even a second, it instantaneously vanishes from its current location. Within 15-20 seconds, a person who has previously viewed the statue dies instantaneously, the statue itself reappearing atop their remains.

SCP-690 - Joke Bandages

SCP-690 is a box of standard, commercially-available adhesive bandages, containing 47 individual adhesives. The logo on the box states that its contents are "Anti-Bandages (box of 64) - for the practical joker!", and that they are supplied by the Factory. When a bandage from 690 is applied to a wound, it will prevent the wound from healing naturally, aggravating it and causing infection. The anomalous property of 690 is that its bandage impose a moderate compulsion on nearby injured subjects to take a bandage and apply it to their wound, regardless of the wound's severity. Once the bandage is applied, the affected user will believe that it is helping heal their wound, and will refuse to remove it.

SCP-691 - A Coward's Way Out

SCP-691 is a blue cassette tape with "Pure Escapism-Limited Edition. 1 of only 250!" printed on it. One side of the tape contains a short foreword by an unknown male voice, introducing a piece of music. On the opposite side, the song "Aquarela do Brasil", translated with S.K. Russel's English lyrics, can be heard. The spoken foreword is harmless and has yet to be linked to any of the effects of 691, aside from encouraging the listener to turn the tape over. Subjects listening to the musical piece have reported visual, auditory, and tactile hallucinations, along with a sense of relaxation and well-being. Subjects with allowed free access to 691 will eventually become capable of doing little more than listening to the tape repeatedly, even forgoing food and drink in extreme cases. As advertised on the tape's printing, it is not the only one of its kind, with 14 additional identical instances of 691 in Foundation custody.

SCP-692 - Revives the Colours

SCP-692 is composed of 57 packages of "Weisser Riese", a brand of washing powder secured by the Foundation from a general store in the Czech Republic, as well as several nearby households. When an article of clothing exposed to "Weisser Riese" comes into uninterrupted contact for at least 15 minutes with a living, multicellular organism, the article, referred to as SCP-692-1) will spontaneously animate and imprint on the organism it is brought before.
  • 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-693 - Knotty Stalker

https://static.tvtropes.org/pmwiki/pub/images/medium_1_5.jpg
An instance of 693.
SCP-693 is a series of 18cm humanoid dolls, each one made from a single strand of string, with onyx beads for eyes. 693 instances will acts as a normal string doll until a piece of hair from the head of a still living human being is placed within a loop of its string. At this point, the doll will begin to move of its own volition, portraying the current actions of whoever it is attuned to. 693 will also project all statements made by said individual, as if it were them. The doll reliably portrays all actions and speech of the attuned individual for a period of nine days, after which the doll's actions will become inaccurate and they will attempt to make the attuned individual commit suicide.

SCP-694 - The Definition of Insanity

https://static.tvtropes.org/pmwiki/pub/images/snowytown.jpg
The location of 694.
SCP-694 is an externally observable time loop in a Vermont town dating to November 2004. The loop repeats every 38 minutes, and it depicts a 52 year old man named Alexander Lang (SCP-694-1), his 6-year-old son Philip (SCP-694-2), and two male kidnappers who identify as "Jake" and "Elwood" (SCP-694-3 and SCP-694-4), who tie up Alexander and carry Philip off in their minivan. Alexander will soon escape his bonds, acquire a gun, and shoot at the car's tires, but shortly after, the car will crash in a ravine, killing both abductors and Philip, at which point the loop restarts. The Foundation has attempted to interfere with the loop in the hope of altering or even ending it, but all attempts to do so have ended in failure.
  • Alien Geometries: Subverted; the criminals think they're driving through one, but nothing about their surroundings confirms this. Per Word of God, it's actually because Philip is a Reality Warper who's unconsciously making the car veer around (with a glass-breaking sound), against the criminals' will, each time he protests that he wants to go home.
  • Jackass Genie: Alexander makes a demand to an unseen entity of a "full repeat" of the last 38 minutes after Philip is killed. Said entity then proceeds to trap everyone involved in an externally observable time loop, and all the Foundation can do is quarantine the area.
  • Shout-Out: The criminals not only use the pseudonyms "Jake" and "Elwood" from The Blues Brothers (as the documentation points out), but the Langs are named after Alexander the Great and his father Philip (although with opposite relationships).
  • Time Loop Trap: A father, his son, and the son's two kidnappers are trapped in the loop. Foundation agents have tried removing or prematurely killing the trapped people, but nothing seems to affect the loop's events. Unlike most examples, the people involved are entirely unaware that they're trapped in a time loop.
  • You Can't Fight Fate: The time loop is so tightly scripted that no outside force can change the sequence of events. Even if the kidnappers and Phillip were to be extracted and secured by the Foundation, they will still die suddenly at the moment the minivan is supposed to land in the ravine.

SCP-695 - Eels

SCP-695 is a species of hermaphroditic parasitic eel. Investigation has shown that 695 may be the result of genetic tampering, with several aspects of its physiology and behavior showing evidence of non-natural evolution. 695 instances will seek out a human host whenever possible, appearing to rely primarily on smell and electromagnetic sensitivity. If an instance inhabits a male host, they will secrete chemicals that prompt their to try and rape women to facilitate the spread the eel's larvae. After maturing inside the female host, the eels will exit via rupturingthe abdomen, after which they will seek out the nearest body of water.
  • 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-696 - Abyssal Typewriter

https://static.tvtropes.org/pmwiki/pub/images/scp696.jpg
696 while it was still anomalous.
SCP-696 is a portable mechanical typewriter with no serial number or manufacturer information. The device was once sapient, and was able to move its keys independently. It had, however, expressed a reluctance to communicate unless it was loaded with paper and a ribbon of red ink. 696 was also capable of understanding messages typed into it, allowing for two-way communication. 696 was able to distinguish between individuals it had communicated with, typing messages which were ominous and grandiose in nature. The typewriter was actually found to have an interest in writing, and after writing a novel that was praised by a D Class for its quality, it grew pleased with itself and ceased all anomalous properties.

SCP-697 - Toxic Terraforming

https://static.tvtropes.org/pmwiki/pub/images/scp_fuel.jpg
697 leaking out of a spilled drum.
SCP-697 is a chemical held in 100 toxic-chemical containment drums, consistent with those used for waste disposal. When exposed to any substance other than the drums themselves, 697 triggers a highly complex chemical process. The process will convert most forms of solid matter around 697 into fully-formed plant-like organisms within seconds of contact, effectively terraforming the immediate area surrounding it. These plants are shown to have the ability to overrun the planet if left unsupervised, and can expel a toxic gas composed of cobalt and argon. The only method of keeping 697 from spreading is to burn it with neon gas.

SCP-698 - Judgmental Turtle

https://static.tvtropes.org/pmwiki/pub/images/698_3.jpg
698 in a protective case.
SCP-698 is a piece of jade carved into the shape of a turtle. Any person who is within approximately 1m of the turtle while making any sort of decision or choice will hear a voice inside their head, telling the subject that they have made a mistake and relays what they should have done instead. In the event that the subject's decision or choice was objectively correct, or the superior choice, the voice will not manifest.

SCP-699 - Mystery Box

SCP-699 is a clear rectangular case 2.5 m x 1.5 m x 1 m in size. Engraved on one side is the Foundation' "Keter" symbol, and the designation "SCP-17591". The object itself is composed of a super-dense polymer much stronger and heavier than any material currently manufactured. This material has allowed for the case to resist all attempts to open, damage, or acquire a sample of it. The contents of 699 are under investigation and currently in dispute among researchers. Said contents are also apparently telepathic and appear differently to most observers, depending upon their individual desires and psychological states.
  • 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-700 - Graffiti Factory

https://static.tvtropes.org/pmwiki/pub/images/1_473.jpg
An instance of 700-2.
SCP-700 is an abandoned factory wherein several graffiti pictures (designated SCP-700-2) can be observed. These images, found inside the factory's rooms, usually depict humanoid creatures, although animalistic creatures have also been observed. All instances of 700-2 have shown the capacity to move around the walls of their rooms, but it is currently unknown if the graffiti are sentient. The central room of the underground floor is a circular hole (designated SCP-700-1) with 0.3ml plastic syringes attached to the walls, all positioned one meter above the bottom of 700-1. The syringes are constantly producing a yellow liquid, composed primarily of human genetic material.

SCP-701 - The Hanged King's Tragedy

https://static.tvtropes.org/pmwiki/pub/images/volgun701.jpg
A still image of 701-1 manifesting.
SCP-701, "The Hanged King's Tragedy", is a Caroline-era revenge tragedy told in five acts. Performances of the play are associated with sudden onsets of psychotic, murderous, and suicidal behavior among the actors and their audience, as well as the manifestation of a mysterious figure classified as SCP-701-1. 701 is essentially a self-evolving memetic virus, transmitted through unknown means through the text of the play. Foundation agents are under standing orders to suppress any performance or publication of 701 whenever it should be found or detected.
  • Bowdlerise: In seeming reference to the original Bowdler, it's noted that many productions attempt to cut out or downplay the more gruesome content of the original script, such as having the murders happen offscreen and removing the references to cannibalism. In fact, there's implications here and there that the original play itself may have been Bowdlerized at some point in its creation, given the oddly happy ending for a play noted to be a 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.
  • Curtain Call: Involves the performers killing themselves and the Hanged King taking center 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 hanged 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 is also very similar to the actual domain of Hastur in the Cthulhu Mythos, which was inspired by The King in Yellow, with the "Hanged King" of the play possibly being a stand-in for Hastur's avatar, The King in Yellow.
    • The play itself is a riff on Hamlet, with a young prince avenging his father against his Evil Uncle at the behest of his ghost.
  • 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 their prior relationship. Survivors can snap out of it 24 hours later, either with no memory of events or 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 hanged. He materializes during a performance, often remaining 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, who is also a Humanoid Abomination.
  • The Moral Substitute: In a hilarious case of irony, it's noted that the play is normally chosen for productions because a look at the script suggests it to be a less violent alternative to classic Shakespeare tragedies, given that it has a happy ending and the few overtly violent elements can be easily watered down.
  • Non-Indicative Name: Zigzagged: the play's title refers to it as a tragedy, but it has a happy ending, which would make it a comedy under the definition of its time. However, when 701 events take place, it becomes anything but a comedy.
  • 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 in 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-702 - The Trader's Residence

SCP-702 is a red vase of unknown design. Human contact with the vase causes an entity (herein referred to as SCP-702-1) to emerge from the vase and initiate contact with the individual coming into contact with 702. 702-1 is a sapient, gas-based life form that communicates through coordinated vibration of the air around it. Upon emergence, the entity greets the subject establishing contact with 702, attempting to persuade the subject into giving it a gift. If the subject refuses, the entity will brutally murder them and takes a single part from their remains.

SCP-703 - Into The Closet

https://static.tvtropes.org/pmwiki/pub/images/703_new.jpg
703 upon initial discovery.
SCP-703 is a wooden closet formerly held in a residential home in New Hampshire. 703's interior is painted white and contains a single light bulb. At random intervals, 703 will enter an active state, during which its bulb will activate. An instance of SCP-703-1 will then appear. 703-1 designates a collection of 452 random objects retrieved from the closet following the completion of its active state. 703-1 instances generally appear to have some relation to their environment and persons exposed to them.

SCP-704 - Dangerous Curves

https://static.tvtropes.org/pmwiki/pub/images/winding_road.jpg
An overhead view of 704.
SCP-704 is a winding road breaking off of and reconnecting to State Highway 96. 704 typically has a looping structure, and is known to enter passive and active phases. During the passive stage, 704 appears to be a winding, static road littered with the remains of vehicles. Once a driver has entered 704, it begins its active phase. The first sign of this phase is an increasingly excited disposition on the part of the driver. As the road becomes more challenging, the driver will begin to declare how much fun they have driving it and will prod the passengers to watch their driving skills, while the passengers show a uniform negative reaction to the road, exhibiting anxiety, paranoia, and fear.

SCP-705 - Militaristic Play-Doh

SCP-705 is a 5oz sample of a soft red variant of the children's modeling compound "Play-Doh". When the lid for the container holding 705 is opened, the material inside will become animate. Shapes resembling small, humanoid forms will emerge from the clay, slowly at first, but soon numbering in tens to hundreds. The material comprising the humanoids will sculpt and come into detail, appearing as miniature infantrymen in military fatigues, equipped with fully functional automatic weaponry. When active, 705 is incredibly violent and militaristic, possessing a highly territorial mindset, and will do everything in its power to overtake what it perceives to be a "strategic" location.

SCP-706 - Perfect Porcelain Doll

SCP-706 is one of the Foundation's more tragic anomalies. She's a 12-year-old European-American girl who is physiologically normal, with the exception of an abnormally high body temperature of approximately 38.5°C, and the fact that her epidermis, with the exception of small areas around the joints, is composed of porcelain. As a result, her skin is extremely thick and fragile, easily able to crack or break when subjected to impacts or excessive movement, a process that is reported as extremely painful. 706 is capable of regenerating this skin layer at a rate consistent with normal skin growth when provided with and allowed to consume appropriate raw materials. She also demonstrates a compulsive need to apply cosmetics to her face, which seems to have ties to her origins, and becomes distressed when she is denied access to said cosmetics.
  • Abusive Parents: Her father beat her when he was drunk and she thinks her mother loved her doll collection more than her.
  • Ambiguous Situation: In the audio recording taken from her home, SCP-706's father screams at her mother not being able to give him a son; the mother cries, "Well, what more do you want? You know I can't have—" which could be interpreted as her not being able to conceive a son, or not being able to have any more children, period.
  • Become a Real Boy: Inverted — SCP-706 was formerly a human girl who became a porcelain doll because her mother loved her dolls more than her. She thought that if she was beautiful and perfect like the dolls, her mother would love her too.]]
  • Homeschooled Kids: For most of her life, she was homeschooled by her mother and rarely allowed outside.
  • I Want My Mommy!: Her interview with Dr. █████████ reveals that she misses her mother and wants to go home.
    SCP-706: ...I just want to go home... mommy... please, just let me go home...
  • Living Toys: She's a girl that somehow became a sentient porcelain doll.
  • Made of Plasticine: The outer layer of her skin is made of porcelain and extremely fragile. Even things like moving too much can break or crack it, although she can regenerate it by eating materials like kaolin and ceramic glaze. For this reason, her containment cell is modified with padded walls and minimal sharp edges.
  • Toy Transmutation: She was once human, but transformed into a living porcelain doll through unknown means. The only hint to how this happened is that she was discovered in her house after a police call regarding a domestic dispute, surrounded by the destroyed remains of numerous porcelain dolls and china dinnerware.
  • Vanity Is Feminine: She is obsessive about maintaining her appearance to the point where she becomes distressed when denied the ability to do so.
  • Wanted a Son Instead: Her father was furious at her mother because he wanted a son instead of a daughter.

SCP-707 - Nesting Dolls

https://static.tvtropes.org/pmwiki/pub/images/scp707_2.jpg
All five layers of the doll, with a quarter for size comparison.
SCP-707 is a Russian matryoshka doll consisting of one central doll and four separating outer layers. When a living human subject removes one or more layers of 707 from its fully assembled state, its anomalous effect will occur, wherein parts of the subject's body will separate and detach, starting with the hair and nails and gradually working its way to the internal organs. No subject has survived the separation of more than 1 layer of 707 to date.

SCP-708 - The Big Orange Forklift

SCP-708 is an orange Toyota 7-Series Forklift with a lift capacity of 8 metric tons. Upon maintaining visual contact with 708 for more than 20 seconds, all subjects are rendered into a state of perpetual enthusiasm. These subjects will exclaim joyous remarks relating to "riding the big orange forklift", not unlike a child. Upon boarding and starting 708, a range of reactions can be observed in the subject. Those with a violent past express the urge to eradicate anything immediately obvious to them, making use of the vehicle's heavy lifting capacity at the earliest opportunity.
  • 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.
  • Tantrum Throwing: Due to the mental effects of the SCP, if someone expresses a desire to ride the Big Orange Forklift but is denied, they will throw a childish tantrum regardless of their actual age or maturity.

SCP-709 - Eye of the Forest

https://static.tvtropes.org/pmwiki/pub/images/scp709.jpg
A treetop photograph of 709.
SCP-709 is a spherical dwelling similar to that of a treehouse, assembled from a kit provided by a company of Vancouver. The interior of the dwelling has been furnished as a small apartment suitable for overnighting. When a person looks out 709's window for a period of more than three to five minutes, they will begin to see what appear to be dimensional counterparts of the forest and its native fauna, such as "four-winged birds" and a range of bipedal cougars walking down a trail.

SCP-710 - Disappearance

https://static.tvtropes.org/pmwiki/pub/images/710_1.jpg
A subject in the later stages of the phenomenon.
SCP-710 is an abandoned housing development located in a suburban neighborhood. Over a process lasting approximately 15 days, any and all organic life that enters and stays inside 710 will ultimately disappear without a trace. Exactly how or why this phenomenon occurs is currently unknown, but there seems to be absolutely no method of reversing the process at this time.

SCP-711 - Paradoxical Insurance Policy

SCP-711 is a device assembled from several highly-modified pieces of high-energy physics equipment. Its primary function is the ability of sending messages and data into the past and of receiving corresponding messages and data from the future. The process of transmitting messages from 711 is strictly one-way, and all messages sent predetermine their own existence and content.

SCP-712 - The Impossible Colors

SCP-712 is a pair of colors, designated SCP-712-A and SCP-712-B, produced by a recovered light-generating apparatus designated SCP-712-1. 712-A is described by test subjects as "reddish green" while 712-B is described by test subjects as "yellowish blue." Subjects who view these colors report feelings of either unease or awe, with neither corresponding to a particular post-exposure effect. Approximately 74% of subjects experience diminished visual ability after viewing 712, while approximately 95% of subjects who initially display diminished visual ability recover within 24 hours.
  • Dead Man's Switch: The apparatus has a fail secure system installed in it. If the researcher viewing the Fictional Colour 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-713 - Click Anywhere Computer

https://static.tvtropes.org/pmwiki/pub/images/scp_713.jpg
713 powered on.
SCP-713 is a desktop computer that runs on the Windows 95 operating system, but has no Internet capability. It bears no external manufacturer’s markings, but internal inspection of the computer reveals it to be composed entirely of hardware commercially available in the late 1990s. 713's mouse may be used to move its cursor offscreen, which remains two-dimensional and resembles a lighted projection without an apparent source. In this way, the computer may be used to "click and drag" individual items within the physical plane, including dragging them inside the computer itself and edited.

SCP-714 - The Jaded Ring

https://static.tvtropes.org/pmwiki/pub/images/scp_714.jpg
The ring after retrieval.
SCP-714 is a jade ring which has been shown to be able to expand and contract to perfectly fit the finger of any subject that touches it. The ring induces several major effects in its current subjects, including exhaustion and reduced mental capacity. In spite of this, the ring is also able to grant whoever wears it complete immunity against harmful chemical and memetic agents. The manner in which 714 causes its various effects has yet to be discovered.

SCP-715 - My Face That I May Be

https://static.tvtropes.org/pmwiki/pub/images/booth.jpg
The booth after discovery.
SCP-715 is a "Take Your Own Photo" photo booth manufactured by Sony in 1972. 715 will not activate unless an individual sits inside it and inputs the necessary currency into the activation slot. The booth has been known to animate sporadically, producing images believed to be modified from previous shots. Upon activation of 715, an instance of SCP-715-A will appear within the radius of the booth. These instances are typically similar to the subject who has just used 715, with the exception of major facial abnormalities, including extensive lacerations, large growths, or the complete absence of facial features.
  • Doppelgänger: SCP-715 is a photo booth that, after taking photos, spawns doppelgangers of the people in a pit under the mall it was found in. These doppelgangers are designated SCP-715-A and look like the originals, but have very deformed facial features. Except this isn't the case. The SCP-715-A instances are actually the humans teleported into the pit, and the "humans" that walk out of the booth are the spawned SCP-715-B doppelganger instances.
  • Facial Horror: After a photo is taken, an instance of 715-A spawns in a pit and attempts to climb out. These instances have major facial abnormalities, extensive lacerations, large growths, or the absence of facial features at all. The truth is different — 715-A are the actual humans, with a perception filter that affects their otherwise-normal faces. The 715-B doppelgangers on the other hand sport the actual facial horror, but have a filter that makes their faces look normal.
  • Humanoid Abomination: The SCP-715-A instances that appear in the pit after a photo is taken appear to be humans, but with horrifyingly-deformed faces. It's actually the normal-looking 715-B instances that are the real abominations.
  • The Reveal: It turns out that the SCP-715-A instances escaping the pit are the normal humans, but with a perception filter that makes their normal faces look horrifying. The SCP-715-B instances who leave the photo booth are the doppelgangers, in turn with a perception filter that makes their horrifying faces look normal. As such, the Foundation had been killing the wrong ones before this realization.

SCP-716 - The Train

https://static.tvtropes.org/pmwiki/pub/images/3571787.jpg
716 in the desert.
SCP-716 is a large locomotive with a variable number of cars, between eight and twenty on average. 716 exhibits a select form of inconsistent topography. While appearing to have a set number of cars from external observation, the train exhibits an apparently unlimited amount of cars when entered. The train is also capable of two forms of transport, travelling in a manner consistent with a locomotive of similar dimensions despite its lack of vital parts, fuel, and conductor. The second form of movement form exhibited by 716 has only been observed with human subjects on board, who will report that the train will suddenly shift and begin to move, rapidly accelerating to top speed. Outside observation will show that regardless of subject reports and received data, 716 remains completely still. Subjects who have entered 716 disappear without chance of recovery when the train begins this form of transportation.
  • 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-717 - The Ambassador

SCP-717 is an abandoned two-story Victorian home, whose anomalous abilities manifest specifically within the remains of the upper story guest bedroom. SCP-717-1 is a white cloth mannequin that is to be kept within this room at all times, seated before the table. Foundation staff are to note its position and markings once per day. A lamp, set of writing implements, large block letters, and a modified Ouija board must be kept on the table. If 717-1 shows signs of movement, a staff member is to sit at the table and remain in the room with it. The staff member present must turn on the lamp and point at the word "WAIT" on the Ouija board, then immediately shut the lamp off. The staff member is then advised to remain quiet and breathe steadily until relieved.

SCP-718 - Eyeball

SCP-718 is an eyeball, roughly the size of a baseball, supported by a long, thin stalk made of tendons and blood vessels. It stands 4ft tall and appears to not need nourishment, nor does it excrete any waste. The eye will turn and follow any living thing in its field of vision, but it prefers to stare at human beings more than other animals. 718's stare being known to induce discomfort and paranoia in a very short time, often resulting in a human subject's attempt to destroy it. If damaged, the eye will explode, showering clear fluid on all nearby surfaces before shriveling into powder. Anything the fluid touches will develop a blister-like bubble that slowly turns black. After 24 hours, the "blister" will burst, and a copy of 718 will emerge, growing to full size over the course of a few days.

SCP-719 - Light-Bringer

https://static.tvtropes.org/pmwiki/pub/images/scp.jpg
719 being inspected while broadcasting a cartoon.
SCP-719 is a General Electric "Porta-Color" television manufactured in 1975. The internal electronics have not been altered from the original design, but the vacuum tubes have been replaced by 8 devices of unknown manufacture, collectively designated as SCP-719-1. When 719-1 is in place, and 719 is supplied with a power source and turned on, 719-1 will radiate electromagnetic radiation in various spectra, including visible light, ultraviolet, microwaves, and gamma radiation. Nearly 60% of the set's emissions are ionizing radiation that are known to bring harm to humans.
  • 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 a few clues in the entry, the Light-Bringer is He-Who-Made-Light, brother of He-Who-Made-Dark.

SCP-720 - Panopticon

https://static.tvtropes.org/pmwiki/pub/images/flapper.png
720-1's base sprite, used for communication.
SCP-720 is an ICRDTA1 program playable on any computing system with read-only memory capabilities. 720 contains a video game consistent with those produced on the Atari Video Computer System. Players control a single character, designated SCP-720-1, as they traverse through 9 levels corresponding to a childish rendition of Dante Alighieri's Circles of Hell, culminating in a final battle against a representation of Lucifer. Occasionally, 720-1 attempts to communicate with the player, or otherwise engages in behavioral patterns which suggest sapience.

SCP-721 - Factory Toys

SCP-721 are three steel cylinders painted black (SCP-721-1, SCP-721-2, and SCP-721-3) measuring 7cm in diameter and 2 cm in height. One side of each cylinder is covered by a steel mesh, and the other by a weak magnet labeled "The Factory". There is no known means of distinguishing between all three instances of 721 apart from activating their anomalous properties, by placing at least 0.2mL of blood from a sapient organism on the mesh side. Upon activation of 721-1, all conscious thoughts of the subject will become audible to those within a 60-meter radius, broadcast in a manner similar to whispering in the listener's ear. Upon activation of 721-2 and the placement of the object on a form of blank medium (i.e. paper, audio tape, videotape, etc.), the subject will gain complete mental control over the content of the media in question, and will be capable of transferring any data they can imagine to the media in question. Upon activation of 721-3, the subject's body temperature will increase approximately 0.3°C per minute. Subjects retain full mobility and consciousness during this time, and suffer no visible effects of the temperature increase, though they report that the process is extremely painful.

SCP-722 - Jörmungandr

SCP-722 is a terrestrial serpent of incredible size, length, and girth, located within and coiled through a network of tunnels of unknown origin within the Kangerdlugssuaq glacier in Greenland. Most of the tunnels in 722's enclosure are completely smooth, though patches on the paths nearest to the head and tail of the artifact are marked with a form of ancient Nordic script. The serpent is currently in a state of prolonged hibernation, and many parts of the creature's body have become embedded in the glacier, possibly due to cave-ins or reformation of the ice over many years. Should the creature awaken, its immense size could pose a significant threat to nearby cities or the world at large.

SCP-723 - Aging Staircase

https://static.tvtropes.org/pmwiki/pub/images/723.png
An interior view of the staircase.
SCP-723 is a spiral stone staircase hewn from ordinary limestone contained within a dilapidated church. When ascended, 723 induces rapid aging in living subjects, and decay in the case of non-living material. Subjects ascending the staircase have not indicated any feelings of pain or discomfort, and seem untroubled by the rapid transformation. Once ascent has begun, subjects have no inclination of returning to the base of 723.
  • 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-724 - Procyon stentor

https://static.tvtropes.org/pmwiki/pub/images/724a.jpg
Radio antennas within 724's radius of effect.
SCP-724 is an anomaly affecting the intersection of an American highway, covering approximately 8m in diameter and occurring only when all of the surrounding radio towers are broadcasting actively. While 724 is active, any raccoon that passes through the anomaly is permanently altered by unknown means. These altered raccoons (collectively designated SCP-724-1) will begin to frequently produce abnormal vocalizations, including human voices, music, static, and modulation/demodulation signals. Subjects within earshot do not appear to understand or control the content of the vocalizations, simply acting as passive receivers.

SCP-725 - Parrot Whale

https://static.tvtropes.org/pmwiki/pub/images/humpback.jpg
725 breaching while agitated.
SCP-725 is a female cetacean with anatomical similarities to the Humpback whale. 725 has demonstrated no mental capabilities beyond standard aptitudes of its parent species, though it does possess remarkable abilities of audio retention and mimicry. These abilities allow for the creature to remembers every sound it hears, as well as the ability to repeat them at will. While it is unknown whether the creature does this for purposes of reproduction or adaptive mimicry at this time, 725 compulsively seeks out new sounds to memorize, prompting the Foundation to replay audio recordings to keep it placated.

SCP-726 - Reconstructive Maggots

https://static.tvtropes.org/pmwiki/pub/images/726.jpg
A group of 726 reconstructing a raw steak.
SCP-726 are insect larvae physiologically and genetically identical to those of the common blowfly. When their eggs hatch on decomposing animal matter, these larvae begin to consume nonliving tissues until none remain, at which point they gather at a central point and regurgitate a continuous stream of living cellular matter, and will multiply in number by unknown means as the volume increases. If uninterrupted, 726 are capable replicating a complete body matching that of the original tissue source from any volume of flesh, regardless of its condition.
  • 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 behavior, 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.
  • Mundane Utility: Due to the maggots' ability to perfectly reconstruct a body from any tissue sample regardless of age, one researcher suggests using them as a forensics tool.
  • Mystery Meat:
    • A can of "potted meat food product" was tested with the maggots, which resulted in [DATA EXPUNGED].
    • When introduced to the patty of a fast food cheeseburger, the end result was two cows and several Norwegian rats.
  • Pet Monstrosity: The large, slug-like mass of cells mentioned above was kept as a pet by a research and named "Brundle".
  • Sanity Slippage: If someone has their wound healed by SCP-726 or eats products created from its reconstituted organisms, their behavior will degenerate over several hours until they act like reconstituted organisms.

SCP-727 - Hephaestus's Forge

https://static.tvtropes.org/pmwiki/pub/images/garden_triclinium_petra_jordan1415.jpg
The entrance of 727.
SCP-727 is a structure resembling an Ancient Greek smithy. The smithy's walls and ceiling are covered with masses of chains made from a material similar to iron. 727's nature makes the chains' length impossible to measure. When a human being enters 727, the chains become active and will forcefully ensnare the subject. This ensnarement does not kill the subject, but invariably breaks many of their bones. If more than one person enters 727 at a time, the chains kill all but one subject by strangulation. Once the chains ensnare a single subject, they manipulate it like a puppet, forcing it to craft a series of objects of diverse nature and exceptional quality until they are thrown out.

SCP-728 - The Forever Room

SCP-728 is a standard shipping container, 12.19m by 2.44m by 2.90m. The interior space is consistent with that of a shipping container. When its doors are closed, the interior experiences the flow of time differently from the outside world. The difference is neither consistent nor predictable, and any equipment which could be used to record the flow of time will function normally within the container. Upon opening the doors, such devices will suffer a catastrophic failure and completely cease functioning, with all data being erased. For this reason, the only reliable method to record the passage of time within 728 is through the use of a human observer.
  • 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-729 - Marble Bath

https://static.tvtropes.org/pmwiki/pub/images/bath.jpg
SCP-729.
SCP-729 is a bathtub carved from marble. Bathing in the tub has been described as extremely relaxing, to the extent that individuals using it for this purpose must be encouraged to leave by an external force. 729’s primary effect will result in all foreign or abnormal objects forcibly expelled from the user's body, including artificial implants, parasitic organisms, and cancerous growths. Approximately 4 minutes after the initial manifestation of 729's effect, bathers begin to suffer from rapid muscle deterioration. Material lost in this way becomes mixed with the water within the bath. Within 6 minutes, this process begins to affect the major organs, extracting them from the body almost intact. Death typically occurs soon after, the only thing left of the subject being their heart.

SCP-730 - Decerebrating Plague

https://static.tvtropes.org/pmwiki/pub/images/creepy_lab.jpg
The lab where the virus is engineered.
SCP-730 is a retrovirus genetically engineered in Italy. The virus is spread by contact with any bodily excretion, and it primarily infects and mutates developing human embryos, resulting in abnormal fetal development. Infected individuals grow to term as physically healthy fetuses, albeit lacking anatomical features located above the brainstem. Once exposed, an individual will continue to harbor a reservoir of the virus without experiencing any ill effects until they contact and expose a pregnant woman, whereupon the virus’s symptoms manifest.

SCP-731 - Rathole Cover

https://static.tvtropes.org/pmwiki/pub/images/scp_731_1.jpg
An overhead view of 731.
SCP-731 is a manhole cover which appears to act as a sort of roving ambush predator. When it is stepped on by a lone human who is not being observed by anyone else, the victim appears to "fall" down the manhole, while in actuality they are sucked into the solid surface of 731. Simultaneously, a single Norway rat, hereafter designated SCP-731-2, is disgorged from the underside of the cover, falling into the tunnel below. It is thought that 731 is somehow able to convert its victims into these rat.

SCP-732 - The Fan-Fic Plague

SCP-732 is an apparent metafictional entity which is fond of altering the Foundation's records and inserting commentary about itself within, said commentary taking the form of nonsensical, fan-fiction styled ramblings. 732’s whereabouts are currently unknown, and enquiries into the nature of the entity have met with little success. While there is no certain evidence, it is theorized that the Foundation's records have entirely been compromised by 732.

SCP-733 - A Pair of Scissors

https://static.tvtropes.org/pmwiki/pub/images/scp733_1.jpg
SCP-733.
SCP-733 is a pair of ornate silver scissors, apparently crafted some time in the 19th century. The scissors were first recovered nestled within the pages of SCP-733-02, a hand-crafted, leather-bound book containing approximately 80 pages. The pages of 733-02 contain 33 black and white photographs and 137 fragments of handwritten text. The authors of the text have been analyzed as belonging to two unidentified individuals who appear to be romantically involved with each other. It has also been discovered that 733 can erase people from existence when used to cut them out of photographs.

SCP-734 - The Baby

https://static.tvtropes.org/pmwiki/pub/images/untitled_657.jpg
734 during "playtime".
SCP-734 is a male human infant between 7 and 8 months of age. Any human tissue that makes contact with the baby will begin to rapidly break down and "flake" away. This effect is most often triggered by skin-to-skin contact, but any living cell from 734 can cause the effect. This "flaking" will begin at the point of contact 2 hours after exposure and spreads at the rate of 0.5mm per minute. No treatment or procedure short of amputation of the affected areas have shown success in halting the progression, with amputation having a success rate of 72%. In light of these effects, the Foundation intends to utilize 734's blood as a weapon.
  • 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.
  • Tyke Bomb: The Foundation is planning on training him to be an anomalous weapon, especially after he scored high on a loyalty index test.

SCP-735 - The Insult Box

https://static.tvtropes.org/pmwiki/pub/images/insultbox.jpg
735, waiting for someone to insult.
SCP-735 is a small box constructed of an alloy of unknown composition similar to brushed-aluminum, featuring a slot on one side. Upon contact with skin, 735 will "awaken" and begin discussion with the person who touched it. These discussions are intensely hostile and personal in nature. A notable side effect of interaction with the box is a sharp increase of adrenaline in the subject, far more so than what would normally be produced in a similar situation. The typical results of interacting with the object are the reduction of the subject to incoherent rage, followed by the attempted immediate destruction of the box.

SCP-736 - The Iapetus Anomaly

https://static.tvtropes.org/pmwiki/pub/images/iapetus.jpg
An interstellar image of Iapetus.
SCP-736 is a phenomenon affecting Saturn's moon of Iapetus. For periods generally lasting several days, Iapetus' orbit will become spontaneously altered by measures of eccentricity and orbital period. Models of these temporary orbits almost entirely consist of the moon undergoing orbital decay, and in most scenarios being projected to collide with Saturn (and other Saturnian moons depending on the projection) at some point within the next 150-300 years. 736's orbits are in direct violation of mathematical models, as well as both classical and relativistic physical principles, and are believed to be directed by an intelligent entity.

SCP-737 - Hungry Train

https://static.tvtropes.org/pmwiki/pub/images/737_new.jpg
737 after feeding.
SCP-737 is a wooden toy train that is hinted to be sentient, and is able to engage in independent locomotion, doing so constantly when given the opportunity. X-ray analysis has revealed that the wooden portion of 737 is merely an outer shell that protects a small brain and biological tissue that make up its actual body. 737 also displays a strong compulsion to consume any object placed in front of it, after which it will assimilate the consumed object into a new carriage for itself.

SCP-738 - The Devil's Deal

SCP-738 is a matched set of mahogany furniture, including a desk labeled SCP-738-1, a straight-backed chair labeled SCP-738-2, and a second office chair styled as an ornate "throne" labeled SCP-738-3, all with brass embellishments and royal purple velvet padding. The anomalous effects of 738 begin when a sentient entity sits in 738-2 while it is positioned in "front" of 738-1, with 738-3 resting behind 738-2. An unseen entity will apparently manifest within the furniture's area, as cameras will show 738-3 moving during the effect, and papers and folders containing papers leaving 738-1’s drawers. The entity will also produce a quill pen and a bottle of ink from the drawers, and will begin establishing a contract directed to the subject, attempting to make a deal with them for whatever they desire. The cost of these deal will consist of something of equal or greater value from the subject.
  • 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), though this may have been due to No Challenge Equals No Satisfaction.
  • 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 it's 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-739 - A Mirrored Booth

SCP-739 is a booth constructed of lacquered oak, shaped into a symmetrical trapezoidal prism. The inward leaning walls inside the object each have a mirror affixed to them, which face one another and emit a set of climbing reflections, giving them the illusion of meeting overhead. If a subject is present within 739 when the door is closed, the door will be impossible to open for a varying period of time, during which the booth shakes violently. After the shaking has ceased, the door can be re-opened, and any subjects within will have undergone a lateral, one-dimensional inversion. All asymmetrical aspects of the subject become reversed, including their internal organs and asymmetrical molecules.

SCP-740 - The Hindenburg Photograph

https://static.tvtropes.org/pmwiki/pub/images/scp740.jpg
A non-anomalous replication of 740.
SCP-740 is a slightly dirty, color-corrected Polaroid photograph depicting the explosion of the Hindenburg airship at Lakehurst Naval Air Station, New Jersey on May 6, 1937. The Polaroid has been determined to be a photograph taken of the original explosion. 740's anomalous traits manifest when it is viewed while in contact with a subject's skin. The subject touching or holding the photograph will hear the sounds of explosions and people screaming. Subjects report difficulty in taking their eyes off the photograph while under its influence. People who hold the object typically report their inability to freely release their grip on it, which they deem very distressing. Many subjects have undergone emotional breakdowns as 740's effects progress, believing that they should have been on the airship and undergoing spontaneous combustion.

SCP-741 - Mysterious Russian Submarine

https://static.tvtropes.org/pmwiki/pub/images/scp_741.jpg
741 in the 1960's, prior to sinking.
SCP-741 is the wreck of a Soviet submarine, which appears to have sunk via rapid flooding following a missile strike. No remains of the vessel's crew have been found, either within the vessel or in its vicinity, and all emergency escape equipment is untouched. The wreck is surrounded by an anomalous pressure gradient. Within the affected region, pressure is much greater than is expected for its depth. Special protection is therefore required for divers to approach the wreck. The records the Foundation has been able to obtain from Russia and the United States about the submarine strongly suggest that it was being used to carry a sort of secret cargo, the nature of which remains unknown.

SCP-742 - Retrovirus

https://static.tvtropes.org/pmwiki/pub/images/virus_44.jpg
742 propelling itself.
SCP-742 is a retrovirus many times more complex than any known naturally occurring virus. 742 infects all cell types, but initially only enters the lytic cycle in helper-T cells, leading to a state of immuno-compromise that allows for total infection. In stage two, 742 affects the nervous system, causing the infected subject to ravenously consume large quantities of protein-rich food, then seek ouy dark, secluded areas (often a cave, abandoned building, or crypt) where they will enter a state of hibernation, slowing the metabolism to the point of apparent death. During this period, the retrovirus completely reverse-transcribes itself into the infected subject’s DNA and de-activates its viral properties. Following this event, the subject is designated an instance of SCP-742-1, a vampiric creature capable of paralyzing human victims to feed on their bone marrow.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/choco_1.jpg
743, active and ready for termination duty.
SCP-743 is a stainless-steel chocolate fountain. On the base of the fountain is a laser-etched logo for Sephra, a company that specializes in producing said fountains. 743 usually appears to be in pristine condition: immaculately clean, well-polished, and completely undamaged. The item can be disassembled into its component parts (base, auger, cylinder, tiers, and crown), but standard examination of the components do not reveal any unusual traits. The fountain has been discovered to houses an untold number of unknown species of arthropod. When the fountain is active, the arthropods perform maintenance work on the fountain to keep it in operating condition. There are also intervals where the insects will swarm out of the fountain and attack any living thing that approaches, after which they will cut pieces off of the intruding organism and bring them back to 743 for nourishment.
  • Mundane Utility: The Foundation uses it as a means of terminating D-class personnel.
  • Nigh-Invulnerability: 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-744 - Assembly Required

See Recap.SCP Foundation Canons under the folder "The Trashfire".

SCP-745 - The Headlights

https://static.tvtropes.org/pmwiki/pub/images/745.jpg
A pair of 745 instances hunting.
SCP-745 is a species of bipedal nocturnal predator. The creature's head is a bloated sack of translucent skin that lacks visible sensory organs and a skull. The brain of the creature can be directly observed, wrapped in a web of bio-luminescent organs below the skin. Living instances of 745 are capable of producing a steady output of 1400 to 3200 lumens from the head. At night, this effectively obscures the rest of the body, giving the appearance of a floating point of light. The creatures hunt almost exclusively in pairs, targeting lone vehicles on remote sections of highway and attempting to run them off the road by pursuing or charging them. Once their prey swerves off the road or comes to a stop, the pair will separate to directly assault and consume the vehicle's occupants.
  • Bioluminescence Is Cool: All specimens of SCP-745 have bio-luminescent organs in their bloated heads. They can display different colors with it, and use it along with their dark bodies while moving in pairs to appear like headlights of a car.
  • Endangered Species: They once established a wide territory around the southwestern United States, but thanks to Foundation forces thinning their numbers since the 1960s, they've been reduced to inhabiting a secured patch of land in New Mexico. It's also mentioned that no nests, lairs, or young of SCP-745 have been found.
  • Light Is Not Good: Their heads produce bright light, and they use it to hunt down humans.
  • My Brain Is Big: Their heads are described to have a bloated sack of clear skin that houses their brain and their light-emitting organs.
  • No Body Left Behind: Victims of their attacks leave no remains behind aside for scraps of their clothes.
  • Silicon-Based Life: Possibly. Their genetic structure is noted to be non-carbon based.
  • Super-Speed: They're capable of running up to 180km/h, allowing them to chase down cars.
  • To Serve Man: Their primary diet seems to be the humans they hunt, and will not eat while in captivity.

SCP-746 - Pseudo-Avian

https://static.tvtropes.org/pmwiki/pub/images/tengu2.jpg
746 in a tree during a failed attempt to capture it.
SCP-746 is a sapient humanoid with birdlike features. The being's face appears aged, with a deep red coloration and beak-like nose measuring 28 centimeters long. Most of the entity's body is covered in rough black feathers. 746 also wears a specialized brace provided by Foundation medical personnel on its left leg, due to suffering a permanent crippling injury. These features imply that 746 is actually a Tengu, a similar half-man, half-bird creature of Asian folklore.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/doll_51.png
One of the dolls linked to 747.
SCP-747 is a phenomenon involving the appearance of seven humanoid entities in any manner of animal masks. All instances of 747 have been successfully identified as deceased children in appearance, congruent with the time of death, excluding the masks. The commonality of these children, according to research, is that they all owned a doll precious to them at their time of death. The children also possess the ability to transform any adult in their vicinity into a similar doll, in a process that gradually measures 21 days.
  • And I Must Scream: The people they turn into dolls are still alive afterward.
  • Creepy Child: Seven ghostly children who can forcibly turn people into dolls.
  • Creepy Doll: They turn people into still-living dolls.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/interior.png
The interior of 748.
SCP-748 is an abandoned industrial complex capable of mass-production of anomalous items through anomalous technology. Posters throughout the facility display motivational/propagandistic slogans, including "A HARD WORKER IS A HAPPY WORKER" and "ACTIVE MINDS LEAD TO IDLE HANDS". Heavily rusted crates are haphazardly scattered throughout the area. Objects recovered from these crates include biologically alive rocking horses which scream when observed, fur coats crafted from the pelts of various unknown species which are perpetually on fire, bowler hats that cannot be removed once worn and make human subjects spew wasps from every orifice, and rotten meat originating from a hybrid species of human, pig, and squid.
  • Ambiguous Situation: Randolph T. Metzger's suicide note makes it ambiguous as whether or not he was willing to be turned into SCP-748-4, if that even is him to begin with.
  • 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.
  • Eldritch Location: SCP-748 became this after its ongoing containment breach, being in a constantly shifting metamorphic state that is impossible to explore and has led to many deaths.
  • Forced Transformation: 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.
  • From Bad to Worse: When the Foundation initially came across it they believed it to have long since ceased function. They soon learn that this is hardly the case and because of this the object class gets upgraded to Keter.
  • 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-749 - Rain Drops

https://static.tvtropes.org/pmwiki/pub/images/749.jpg
SCP-749.
SCP-749 is an apex predator superficially resembling a centipede, approximately 3m long with two to three hundred pairs of legs. Each individual 749 specimen possesses powerful forcipules which secrete a powerful acidic compound. 749 demonstrates a predilection for hunting during rainstorms, appearing to be familiar with urban settings. Its preferred hunting methods consist of climbing up the walls of domiciles, using its forcipules to gain entry, then feeding upon sleeping individuals within. 749 also demonstrates the ability to camouflage its hue to match the surface it is currently residing on, and uses its legs to walk in a pattern replicating the sound of raindrops. In all reported 749 attacks, the creature had fed upon the smallest unaccompanied individual.

SCP-750 - A Different Outlook on Life

https://static.tvtropes.org/pmwiki/pub/images/contact_lens.jpg
An instance of 750 on a subject's fingertip.
SCP-750 is a collection of 24 pairs of contact lenses, presumably designed to correct myopic or hypermetropic vision. When a pair of 750 is applied, they attach to the subject's cornea and become unable to be physically removed by the wearer, though others can still remove them. Personnel exposed to 750 have reported feelings of dizziness and blurred vision upon wearing the lenses, as well as abnormal variations to their sights, including walls, ceilings, and floors being covered in a substance similar to biofilm, a dark red sky with black clouds, food becoming piles of human viscera, visions of insects emerging from their skin, samples of written language becoming an unidentified language, paintings depicting violent scenes from human history, and statues becoming depictions of unworldly creatures not identifiable with any known species. The effects will increase the longer the lenses are kept on, and are known to become permanent after enough time has elapsed.

SCP-751 - Organ Eater

https://static.tvtropes.org/pmwiki/pub/images/scp_751.png
751 sitting on a reef.
SCP-751 is an amorphous parasitic organism that feeds on the organs of mammalian creatures. The majority of 751's mass consists of an unknown substance with a gelatinous consistency, with red veins running through it. Analysis has revealed that these veins contain a mix of blood from its progenitor's hosts, along with varying anesthetics and immunosuppressive drugs. 751 begins its feeding process by settling atop a sleeping host's stomach region, where it will enter through the skin via osmosis. Over the next 3 to 4 days, 751 will digest the host's stomach, using it to build up its mass for further expansion. It will then slowly expand to engulf and digest the other organs in the host's body, generally starting with the intestines and moving to the liver, kidneys, and lungs.
  • 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.
  • Face Full 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

https://static.tvtropes.org/pmwiki/pub/images/scp_752.png
A still from an expedition into 752.
SCP-752 is an underground city with a population of approximately 10,000. A shield built of an unknown metal surrounds the entire city and blocks all known forms of signaling and radiation, including sonar. 752 has also been found to currently possess technology significantly more advanced than any city on the earth's surface. SCP-752-1, the inhabitants of 752, appear physically human, though the social behavior exhibited in large groups bears no resemblance to that of humans, or any other social mammal (although parallels to this form of socialism exist in ants and other social insects). Individual instances of 752-1 possess no self-interest whatsoever and are motivated solely by the desire to expand 752 for the "greater good".
  • Artificial Human: The "Eudaimoniacs" were built by Alpha to be what they are.
  • Beneath the Earth: Their city is located beneath a classified mountain range.
  • Blue-and-Orange Morality: Taboos don't exist at all in SCP-752. SCP-752-1 instances are very much willing to kill, be killed, or kill themselves all for the advancement of their society. According to Alpha-1, the concept of morality wasn't programmed into the Eudaimoniacs as he found it to be a flaw in human societies.
  • Closed Circle: Sealed inside a radiation-proof shield, the Eudaimoniacs believe that their city is all that exists. A group of their creators and the Foundation would prefer to keep it that way.
  • Explosive Breeder: The Alpha team secretly engineered the Eudaimoniacs to create special nursery structures that allow them to procreate at a much faster rate than regular humans. In the span of 70 years, their population went from 124 to about 3000.
  • 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: Deconstructed and Played for Horror. SCP 752-1 was built to rationally and 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.
  • Repressive, but Efficient: Subverted. Everyone in SCP-752 is entirely willing and compliant with their place in their society and are content with doing literally nothing else but their jobs, all to make their society as efficient and advanced as possible.
  • 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.
  • Workaholic: To an extreme degree. Every SCP-752-1 instance from the lowest caste to the highest work themselves to death on their assigned job and do nothing else but their job.

SCP-753 - Automatic Artist

https://static.tvtropes.org/pmwiki/pub/images/753_new.jpg
SCP-753.
SCP-753 is a small, but highly advanced automaton. 753 possesses two pincer-like limbs protruding from its main circular body, which it uses to slowly move itself across the ground. At the center of the automaton's body is a red sensory organ similar in structure to that of a human eye. This eye appears to be organic, but it is likely artificially produced. The eye is also damaged, leaving 753 partially blind. The "Marshall, Carter and Dark Ltd." logo has been engraved on 753's back. 753's primary purpose appears to be the creation of paintings. The paintings produced by machine are highly realistic and often do not correspond to real locations. The most recent paintings created by 753 have mostly involved, in some way, the machine's death.

SCP-754 - Illustrated Climbing Vine

https://static.tvtropes.org/pmwiki/pub/images/scp_754.png
754 rendered in pencil and crayon.
SCP-754 is a flowering vine similar to the species known as "morning glory" or "field bindweed". The leaves and vine are red with delicate black veins, and flowers, when present, are red with black mottling. 754 can grow across any surface, including those typically resistant to plant growth and bodies of water too deep for root stabilization. 754 is not limited to normal growth patterns, as it can grow in paper media in the form of an illustration (designated as SCP-754-1). 754-1 manifests itself as an additional image in hand-rendered illustrations, indistinguishable from the original contents in terms of medium, style, and scale. Illustrations containing 754-1 will animate and change in response to continuous growth.

SCP-755 - "Watch for the white bird"

https://static.tvtropes.org/pmwiki/pub/images/755.jpg
One of 755's messages on the steps of a private residence.
SCP-755 is a graffiti artist who, at the time of archiving, is rumored to be active in the western United States. The vandal regularly travels large cities, leaving behind instances of SCP-755-B, graffiti whose style and form vary by instance which invariably reads "WAtCh For thE WhitE Bird." Persons who read the graffiti are invariably injured or killed in apparent accidents involving a white bird.

SCP-756 - Miniature Solar System

SCP-756 is a miniature solar system consisting of a yellow sun with six planets, each with various moons and satellites, orbiting around it. This system is restricted to the confines of a single cell, which itself is now devoid of gravity and atmosphere, believed to be brought about by 756’s "birth". Nearly all of the planets within 756 are inhabited by varying forms of life.

SCP-757 - The Fruit Tree

https://static.tvtropes.org/pmwiki/pub/images/757_7.jpg
757 laden with fruit.
SCP-757 is a fruit producing tree similar to the common peach tree. Every day, at dawn, 757 produces new fruits, collectively designated SCP-757-1. Human subjects viewing 757-1 while they remain attached to the tree display a minor compulsion to consume them. If a subject consumes any part of an instance of 757-1, a new organ will form in the subject's abdomen, in a process reported to be highly painful. Over the course of a week, a new fruit of the type consumed by the subject forms inside this organ, causing further pain and visible swelling before it is forcefully expelled through the esophagus.
  • 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-758 - Spell Check - "Vasili"

SCP-758 is a male Russian child who is commonly addressed as "Vasili", who was diagnosed with extremely low functioning autism at the age of four. Despite claiming that his native language is the only one he can actually understand, Vasili has been found to possess the ability to recognize and correct errors in the technical aspects of any additional language able to be spoken, written, or programmed, including dead and extraterrestrial languages. Due to the relative simplicity of his anomaly and his youthful age, Vasili's containment procedures are largely minimal.

SCP-759 - Sourdough Starter

SCP-759 is a 500g mass of sourdough starter composed primarily of wheat flour and water. The starter's active component is an ongoing culture of wild yeasts in symbiotic balance with multiple strains of Lactobacillus and Acetobacter. What distinguishes 759 from ordinary sourdough is its ability to absorb the emotional state of the individuals who tend to it, feed it, and use it for baking, and will transmit said emotional state (or a close derivative thereof) to anyone who consumes the resultant confection. The length of exposure and the intensity of the currently-absorbed emotional state act as variables for the effect.
  • Baguette Beatdown: In one test, two baguettes were made by a D-class with anger management issues and poor impulse control. After the testers ate half of the first one, they started fighting over who should get the second; then one tester picked up the second loaf and tried beating the others senseless with it.
  • 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-760 - The Groomers

https://static.tvtropes.org/pmwiki/pub/images/scp_xxx_2.jpg
One of 760.
SCP-760 are three specimens of a vaguely humanoid species of animal. The skeletal and muscular system of 760 differ greatly in areas from those of humans, the most notable effects of these differences being the legs extruding perpendicular to the torso and an ape-like curvature of the spine that results in a preference for the creatures to walk on all fours. 760 are also shown to each have a mass of hair where the face would be on a human, which apparently holds some sort of sensory function that allows the creatures to see in the dark. 760 are often show enjoyment around humans, displaying behaviors reminiscent of dogs and primates. The creatures primarily feed on blemishes, secretions, and dead matter shed by humans, and they do so by vocalizing a frequency that induces sleep in nearby humans, whereupon the creatures will manifest a long tongue to lap up their food source.

SCP-761 - Slightly Less Dangerous Trampoline

SCP-761 is a steel frame trampoline, 2m in diameter and 3.5 meters tall. Any solid object or living subject that impacts the trampoline's surface with a momentum exceeding 250 kg*m/s will vanish upon impact. Testing has determined that the object is instantaneously transported to a completely random location up to 15m away from the trampoline, all while retaining its momentum. This will often result in the subject being merged with and/or entombed inside solid material and asphyxiating.
  • 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

SCP-762 - Immortal Iron Maiden

https://static.tvtropes.org/pmwiki/pub/images/scp762.jpg
SCP-762.
SCP-762 is a torture device similar to an iron maiden. Any person placed inside 762 appears to enter a state of suspended animation, during which they no longer need food, water, or air when inside the device. Subjects also appear to be immune to the effects of disease or injury when inside 762, including the wounds inflicted by the instrument itself. Subjects do, however, remain conscious inside 762, and the experience is described as being very painful.
  • 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.
  • Immortality Field: Played for Horror. Any person placed inside it enters a state of suspended animation and they would no longer need food, water, or even air and they are immune to disease and injury (when it was found, it contained someone who was probably stuck inside for centuries)... except those caused by its own spikes, because it's an Iron Maiden. As a torture device, its primary purpose is likely not to keep people alive but to prolong the victim's suffering. The person inside is conscious the whole time and the experience is described to be very painful.
  • 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

SCP-763 is a colossal mass of organic human tissue occupying approx. 300 square meters of space, with an estimated mass of over 4,000 kg. Much of the mass is composed of muscular tissue with an abundance of blood vessels. This tissue is highly atrophied and non-motile, though despite lack of use, there is a great amount of blood flow at all times. Most of the structure is relatively thin, allowing for the blood flow to diffuse the high heat generated by the central mass: a large lump approximately 2m high. This flow is provided by a large collection of hearts arrayed throughout 763's structure. All organs of the human body are present in 763, located in a relatively even distribution throughout the system. The mass has the ability to assimilate human subjects, having done so to 7 Foundation personnel since it was brought into custody.
  • 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. The most notable features are a cluster of brains, and a half-absorbed body previously belonging to the local veal factory's former owner.

SCP-764 - The Obscene Show

https://static.tvtropes.org/pmwiki/pub/images/punch_judy.jpg
764-1 and 764-2.
SCP-764, consisting of SCP-764-1 and SCP-764-2, is a pair of Punch and Judy hand puppets that display no exceptional characteristics under visual inspection. When observed by individuals with no barrier between them and the puppets, an immense compulsion comes over a single person to utilize the puppets to "put on a show". All other subjects in the area feel an overwhelming urge to watch the show, regarding all events taking place during the performance as the height of entertainment. After a period of three to five minutes, an individual will be chosen from the audience and brought forward to participate in the show. A lighthearted exchange will occur between the chosen subject and the puppets before the show resumes, but afterwards, the puppets will brandish appropriately sized weapons and begin to viciously attack the "volunteer". When the volunteer is killed, the process will repeat until no other audience members remain, after which the puppets will conclude the show by killing the puppeteer.
  • 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-765 - Duck Pond

https://static.tvtropes.org/pmwiki/pub/images/duckpond_new.jpg
765 on a sunny day.
SCP-765 is a duck pond discovered in South Carolina. This pond appears to emanate an emotional effect in subjects that approach it, resulting in what researchers have called "serenity." All subjects exposed to 765 report relaxed feelings, contentment with their life, and justification with their life choices. After seven to twelve days of continuous exposure, the effect changes to induce feelings of lethargy, apathy, boredom, and depression.

SCP-766 - Human-Shaped Anomaly in Space

SCP-766 is a human-shaped spatial anomaly on a tropical island that matter cannot physically pass through, effectively making it an invisible "statue" of a person. Applying plaster to the anomaly has allowed researchers to study its physiology, showing that it is in the shape of a nude, anatomically correct woman in her late 30s, with features consistent of the native population of the island. The anomaly is depicted running and looking behind, above, and to the left of itself. The right hand forms a fist, leaving a hollow, cylindrical opening between the fingers, suggesting that it once held an implement of some sort. A band on the left shoulder is indented in a way that the strap of a satchel might cause. The anomaly's facial expression appears both exhausted and startled.

SCP-767 - Crime Scene Photographs

SCP-767 is a series of photographs taken with an "instant" camera on self-developing film. The photographs (designated SCP-767-1 through -12) are labeled "1" through "12" in the lower-left corner, though the numberings are listed in reverse order to the apparent chronology of events they depict. When viewed in reverse, 767-12 through 7 follow a first-person perspective of an individual entering a room and examining a single table. 767-6 is a top-down view of the same table, which (in new iterations) alternately reads "ON THE CEILING" or "ITS ABOVE YOU", written in a red substance appearing to be fresh blood. 767-5 and 4 indicate a viewpoint of someone who is facing downwards as they are lifted into the air above the table, with small wisps of dark smoke visible along the edges. 767-3 through 1 portray the subject's corpse, initially intact but with heavy lacerations. Subjects who view the photographs in specific designations will showcase varying negative emotional and psychological effects.

SCP-768 - Long-Range Alarm Clock

SCP-768 is a Seiko travel alarm clock that is in all regards physically identical to a regular unit of its model. The clock's anomalous property is activated when the alarm is set and activated. Instead of emitting a beeping sound, 768 will instead cause every alarm and alert system within 300m of the clock to instantaneously activate. As the clock's components, when disassembled and individually analyzed, show no irregularities, the reason for how 768 accomplishes this is ability currently unknown.

SCP-769 - Ancient Encyclopedia

https://static.tvtropes.org/pmwiki/pub/images/cup_7.jpg
769 in a subject's hand.
SCP-769 is a cup made of pottery with a golden glaze, covered with a white residue. Several preserved parts from various sea creatures are stuck in this residue. When a subject drinks from the cup, new information is written directly into their brain. In the process, however, the subject will lose memories they already possess, much like a computer's storage being overwritten. The memories lost are unpredictable, but are usually comparable to the information gained. All water from the cup must be drunk in one sitting, or the subject will gain fragmented, unreliable information.
  • 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-770 - Nuclear Slime

https://static.tvtropes.org/pmwiki/pub/images/770.jpg
770 in a beaker.
SCP-770 is a strain of mold similar in appearance to the common slime mold. When present on a surface, 770 will absorb any radioactive isotopes in its vicinity. The mold will also absorb isotopes larger in atomic mass than iron-56, with a preference to heavier isotopes. During ingestion and reaction, 770 will emit significant quantities of ionizing radiation, including alpha, beta, gamma, neutrons, and hard x-rays. This output is so substantive that an adult human would receive an LD50 level dose of radiation after minutes of exposure to 500 milligrams of active 770.

SCP-771 - Self-Repairing Biological AI

SCP-771 is an artificial intelligence that appears to be constructed out of both organic and mechanical components. When 771 undergoes an error or shuts down, a swarm of miniscule robots will be released from a hatch within 771. These "nanobots" will swarm over 771, then start "searching" the surrounding area. The swarm will break down any and all metal in the area, returning to 771 in an attempt to "patch" the damaged areas. The swarm will also target any active vertebrate during their search. Upon contact, the swarm will proceed to sting the subject, injecting a fluid that completely freezes all muscles in the body. Once frozen, the nanobots will move the subject into close proximity to 771, and will proceed to cut off portions of tissue. The swarm will then bring the tissue back to 771, attaching the pieces to the pre-existing biological components.

SCP-772 - Giant Parasitoid Wasps

https://static.tvtropes.org/pmwiki/pub/images/scp_772.jpg
An instance of 772 preparing to lay eggs in a dead cow.
SCP-772 is an unknown species of wasp, superficially resembling members of the genus Megarhyssa. A mature adult is typically 60cm in length, from head to abdomen, excluding the antennae and ovipositor. The barbed ovipositor is used to penetrate a host and deposit anywhere from 5 to 20 eggs. 772 is meticulous and almost surgical during oviposition, making an incision no longer than 3cm, and during this time, the host is paralyzed and/or comatose for several hours until the wound can heal sufficiently. 772's eggs have an incubation period of 4 to 12 days. Upon hatching, the larvae begin consumption of the host's tissues, gradually working their way into the depths of the the body.
  • 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-773 - Voodoo Dartboard

https://static.tvtropes.org/pmwiki/pub/images/fivesdartboard.jpg
The dartboard set up for testing.
SCP-773 is a standard English dartboard with a diameter of 451mm. It is divided into the standard twenty segments and an inner and outer bullseye ring, along with the standard double and triple bands. When a dart with a person's name written on it is thrown onto the board from a distance of at least three meters, a random injury will be afflicted to said person. The severity of these injuries depend on where the dart impacts the board.

SCP-774 - Whistlebones

https://static.tvtropes.org/pmwiki/pub/images/skull1.jpg
The remains of a subject who made contact with 774.
SCP-774 is a chemical byproduct which, upon contact with the skin, permeates the body's tissues and selectively attacks the skeletal structure, dissolving the minerals of bone and leaving only the soft collagen. This process can occur in minutes or over the course of days, depending on the degree of exposure. Subjects typically die following the collapse of the ribcage, or damage to the spinal cord due to the loss of the spine. The only part of the skeleton left unaffected by 774 is the skull, which enlarges in size and gains the ability to produce whistling sounds similar to birdsong.

SCP-775 - Hungry Ticks

https://static.tvtropes.org/pmwiki/pub/images/hungrytick.jpg
An engorged 775 instance.
SCP-775 is a species of tick of a significantly large size, with most un-engorged adults growing to the size of a nickel when fully matured. 775 often travel very rapidly along solid surfaces, and are capable of making small leaps. The ticks will feed on any vertebrates in their vicinity, and will continue to feed on the host until it is no longer capable of providing nutrients. They also lay eggs inside the host, their larvae burrowing under the skin upon hatching and attempting to feed on tissues directly. The ticks' host will eventually be hollowed out, with only the outer layers of skin remaining.

SCP-776 - The Youth Cult

SCP-776 is a remote town in the northwest corner of Russia. The town's populace, designated SCP-776-A, claim to have achieved the means of extending the process of biological aging. These people do so through a ritual designated SCP-776-B, wherein a person younger than the person or persons performing the ritual are offered as human sacrifices. Because of the logistics and purpose of the ritual, children are the most common individuals sacrificed.

SCP-777 - Kingdom of Sand

https://static.tvtropes.org/pmwiki/pub/images/771_1_new_0.jpg
A dune within 777.
SCP-777 is an area of desert referred to by locals as "The Kingdom of Sand". 777 demonstrates anomalous properties when sand in the area comes into contact with any type of liquid. The moisturized sand will animate, taking the shape of an animal proportionate to the amount of sand exposed. These entities will hereafter be referred to as SCP-777-1. Instances of 777-1 will behave aggressively to any organism that enters 777, attacking on sight. 777-1 will hunt prey single-mindedly, but on several occasions have followed intruders out of 777 and to nearby towns.
  • 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-778 - Paradise Falls

https://static.tvtropes.org/pmwiki/pub/images/778_4.png
One iteration of 778.
SCP-778 is an area of land of undetermined size currently defined on all maps, signs, and media representing it as a hiking trail leading to a destination known as "Paradise Falls". 778 displays inconsistent topography and is potentially dangerous to civilians. Instead of leading to "Paradise Falls", 778 will instead often lead to winding, inconsistent paths around its current area. 778 also appears to "regenerate" on a somewhat regular basis, usually every 10-25 years. When this occurs, its name will change, it will shift to another area, and all maps and signs will change to reflect this.

SCP-779 - Brownies

https://static.tvtropes.org/pmwiki/pub/images/779_new.jpg
A single specimen of 779 in the wild.
SCP-779 is a species of insect similar in appearance and behavior to bees or wasps. Specimens of 779 are typically colored red and black, and are known to construct nests in the residences of humans, forming them from whatever resources are available. 779 is also known to sting the occupants of their chosen residence, injecting them with hallucinogenic venom. Injected subjects will perceive 779 as small humanoid figures with wings, and believe that they are assisting with the maintenance of the residence, even if the residence undergoes structural collapse. Continued exposure to the venom will result in victims viewing 779 them as their "children" and defending them from threats.

SCP-780 - Seed Bead

https://static.tvtropes.org/pmwiki/pub/images/bead_6.jpg
780 on a table.
SCP-780 is a 1cm bead shaped like a rounded gem with numerous facets and a hole at its center, which appears to be made of a clear amorphous substance. When a plant is placed within 10 meters of 780, it begins to levitate and will fly towards the plant. How the bead detects plants is unknown at this time, but if restrained, the bead will become increasingly agitated until the plant is removed from its radius. Should 780 be allowed phyiscal contact with a plant, the bead will stick to it for 5 seconds before dropping to the ground. A shoot will then begin growing from the central hole minutes after exposure, gradually becoming an exact replica of the original plant within 24 hours. While it is unknown how 780 accomplishes this at this time, it has been discovered that the ability also extends to photographs, illustrations, recordings, and textual descriptions of plants as well.

SCP-781 - Unwitting Dreamshaper

SCP-781 is a man of Mediterranean descent who, while asleep, involuntarily manifests his dreams into a physical form. The majority of these manifestations are hostile and highly-dangerous, and they are prone to killing 781 on average of three times per week. Though he does not exhibit resistance to injury or death beyond the limits of a normal human, 781 seems to utilize an ability of automatic resurrection. 12 hours after 781's physical "death", the corpse will disappear, and a fully healthy replica of 781 will appear within 10m of the site of his previous death after an additional 12 hours.

SCP-782 - All-New You

SCP-782 is a self-help book entitled "Three Easy Steps to an All-New You". When read by an individual capable of understanding its content and message, 782 instigates a Type-P memetic effect upon the victim, altering the chemistry, connections, and architecture of the subject's brain. The effect occurs in three stages, the first of which is that the victim begins to feel numbness in random areas of the body. The second stage occurs after this numbness fades, where the victim is no longer able to control the affected areas. The affected individual has no way of influencing the movement of the affected body parts beyond manipulating the area which the affected parts are attached to. The third and final stage of 782's effect has the affected areas begin to engage in autonomous movement, attempting to perform tasks independent of the desires of the victim.

SCP-783 - There Was A Crooked Man

https://static.tvtropes.org/pmwiki/pub/images/arm3.jpg
The arm of a 783 victim.
SCP-783 is a hostile entity that preys upon the residents of Temby, a rural hamlet in Oxfordshire, England. The entity will enter a period of activity every 12 years, which will last roughly seventy days over the course of the fall and winter months, during which 783 exclusively attacks citizens who are alone and indoors after sunset. Buildings housing 783's current target will rapidly degrade in structural integrity, visible as faults and breaks on the outer facade that the structures a crooked appearance. 783's victims exhibit gross deformations in the body structure as the result of dozens of compound fractures along the bones.

SCP-784 - Christmas Cheer

https://static.tvtropes.org/pmwiki/pub/images/scp_784_1.jpg
A house in 784.
SCP-784 is a Texas neighborhood where all houses are occupied by a variable number of instances of SCP-784-1, adults who wear sweaters typically associated with holiday gift giving. All instances of 784-1 express traits commonly associated with "Christmas spirit" throughout the year. These traits include singing Christmas carols, performing plays commonly associated with the birth of Christ, and various other eggnog-related festivities, all of which are engaged in daily. Human subjects who do not meet 784's criteria for "Christmas spirit" will be assaulted by 784-1, incapacitated, and forcibly directed into the nearest household. Attempts to retrieve affected personnel have been met with great resistance on both the part of 784-1 and the affected individual themselves.

SCP-785 - A Chain Restaurant

https://static.tvtropes.org/pmwiki/pub/images/uncle_5.jpg
A 785 location with the sign redacted.
SCP-785 is a chain restaurant named "Uncle [REDACTED]'s [REDACTED]". Propagation of 785’s effects will begin if the name (SCP-785-1) is mentioned in conversation in a large public area. One to six months after this occurs, an individual present at the location where the initial seeding was performed will establish an instance of the restaraunt. The effect will manifest annually on the first Friday of May, when 785 will advertise a "Spring Special." All customers and employees of any existing instance of the restaraunt will be affected. Between 1600 and 1830 hours, any customers who previously consumed beef or bread served during that particular day will report to the restaraunt. The staff will proceed to stab the members of affected customers twelve times with bronze-tipped spears. After all customers have expired, the employees will place their bodies on the floor, proceeding to eat the bodies and burning the remains afterwards.

SCP-786 - Funnel Factor Twelve

https://static.tvtropes.org/pmwiki/pub/images/scp_786.jpg
786 in a parking garage.
SCP-786 is a funnel composed of high-density polymer. Visual inspection of 786's interior from either end has the interior appearing to be perfectly cylindrical. The view through the far end's opening is enlarged or reduced accordingly. Any object that passes through 786 will have its physical dimensions altered by a factor of twelve, either enlarging or shrinking depending on which direction the object passes through the funnel. The change is noted to be permanent, but can be reversed if the object comes back through the funnel in the opposite direction.

SCP-787 - The Plane That Never Was

https://static.tvtropes.org/pmwiki/pub/images/787.jpg
787 on an airfield.
SCP-787 is a Boeing 747-200 airliner of unknown manufacturing date, hull number, and call sign. The vehicle contains the bodies of 515 deceased individuals, henceforth referred to as SCP-787-A. All 787-A specimens are in advanced stages of decay, but have shown no signs of further putrefaction since 787's recovery. The cause of death varies among specimens, with causes including strangulation, exsanguination, drowning, starvation, bullet wounds, stab wounds, and blunt force trauma. Certain mutilations are common throughout 787-A specimens regardless of the individual cause of death, including removal of the tongue, scalping, carving of Cyrillic letters into the left palm and removal of fingertips. The plane's machinery is found to be in perfect condition while the non-mechanical components have been sucumbing to decay. While in Foundation custody, the plane manifests harmless anomalous phenomena related to typical hauntings every few years.
  • Noodle Incident: The event that led to the plane's anomalous qualities. It wasn't a crash- the plane is still in perfect working order, and the passengers were killed by a variety of methods, including strangulation, gunshot, exsanguination, blunt force trauma, and drowning. Somehow an Indian man in a suit got into the plane's waste storage tanks. There's some consistency in how corpses were mutilated (fingertips cut off, random Cryllic letters carved on the left hand, scalping), but no indication on what did it.
  • Noodle Implements: The items the Indian man was carrying. He had a surgical mask and gloves, cinnamon-flavored mints, a shotgun, a switchblade, the flight log, an Eye of Horus amulet, and a ticket stub for Return of the Jedi.
  • The Spook: Occasionally, shadowy humanoid figures have temporarily appeared on the plane. Nobody knows what they are, or what connection they might have to the plane's current state.
  • Timey-Wimey Ball: Something timey-wimey happened on this plane. At very least, some of the passengers dead on the plane are very much alive in the present.

SCP-788 - Magma Carp

SCP-788 is a creature resembling an African carp composed entirely of ultramafic magma, with a 'skin' of cracked picritic basalt. The creature is currently estimated to have a core temperature of approximately 1475 degrees Centigrade, though the skin temperature is typically much lower. 788 shows typical behaviors of a freshwater fish, and is known to consume ores and minerals, iron and magnesium seeming to be its preferred choice of nourishment. It is hypothesized that there may be more than one instance of 788 living in the Earth's core.

SCP-789 - Internet Predator

SCP-789 is an entity residing within an abandoned, albeit well-kept, three-bedroom two-story house in the outskirts of North Dakota. When the house recieves an internet connection, 789 will manifest as a working desktop computer with webcam, controlled by a pubescent child. The entity will spend several hours a day contacting and interacting with adult civilians within the continental United States. 789 appears to specifically target pedophiles, fabricating complex-but-believable stories and utilizing video chat programs to lure and gain its contacts' trust. 789 will work to lure its prey to visit the house, and will kill and devour those who comply with its requests

SCP-790 - Blood?

SCP-790 is the blood of a human identified as Mr. [REDACTED]; hereafter known as SCP-790-01. This blood shows itself to be animate, emanating almost constantly from 790-01’s pores, tear ducts, and salivary glands. The blood also emenates from a number of deep wounds and scars that cover at least 70% of his body, believed to be produced by 790 itself over the course of several months. Despite being positively identified as human blood, 790 is not only sapient, but displays intelligence and relative exposure to air does not result in clotting and drying. 790-01 himself appears to interpret his anomaly as divine providence, claiming to have been contacted by supernatural forces that insist he care for and nurture his animate blood until the day he dies.

SCP-791 - Water Orb

https://static.tvtropes.org/pmwiki/pub/images/waterorb.jpg
791 in a garden, acting as a fountain.
SCP-791 is a large mass of liquid water held in a spherical shape by an unknown, undetectable force. 791 is impossible to "splash" due to its shape, though portions of the water may be drawn out via the hands or mouth. 791 reacts to non-biological materials as if it were a sphere of solid concrete. 791 may be lifted, rolled, or otherwise manipulated in this way, but acquiring samples with materials such as stone or metal is extremely difficult due to the extreme weight and durability of 791.

SCP-792 - The Body Farm

SCP-792 is a wooded area measuring 4 square kilometers. At any given time, 792 contains between 37 and 4,500 human corpses, designated SCP-792-1. Instances of 792-1 emerge from the ground at random intervals at a rate of roughly 10 per day. After emergence, decomposition will proceed as expected in 792's environment. Once a year, between the dates of September 2nd and October 31st, 90 to 130 humanoid figures in hazmat suits (hereby referred to as SCP-792-2) will climb out of a pond in the center of the area. 792-2 are sapient and capable of communication in English, and will place instances of 792-1 in the pond.

SCP-793 - The Ghost Sickness

https://static.tvtropes.org/pmwiki/pub/images/793_1.jpg
793 in a drop of blood.
SCP-793 is described as a hyper-reproductive variant of Congo trypanosomiasis (the protozoa known for spreading "African Sleeping Sickness") which inhabits an abandoned medicinal center. When a human subject enters the zone of denial, 793 will spontaneously manifest inside the circulatory system. The symptoms appear to be dissimilar to those of normal Congo trypanosomiasis, with a notable increase in hysteria and swelling of the lymph nodes. The opposite effect occurs if the subject leaves the zone of denial, wherein the protozoa will spontaneously disappear and the subject will heal.

SCP-794 - Desert Shipwreck

https://static.tvtropes.org/pmwiki/pub/images/scp794.png
SCP-794.
SCP-794 is the derelict remains of an oceangoing vessel located in the Sahara Desert. SCP-794-02 is an enormous mass of living nervous tissue integrated into the cargo hold of 794, currently estimated at approximately 167 kg in weight. Living human subjects that approach within 1400m of 794 report feeling an increasing compulsion to enter the vessel. At this point, affected subjects will attempt to enter by any means possible, and must be terminated in order to prevent them from approaching the wreck. Once within the vessel, affected subjects will enter the ship's cargo hold, whereupon they will immediately collapse and cease all life signs. 794-02 will then absorb the deceased subject into itself to increase its mass.
  • 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.
  • Exactly What It Says on the Tin: SCP-794-01 is a shipwreck in the middle of the Sahara Desert.
  • "Instant Death" Radius: Anyone who enters the ship's cargo hold (which contains SCP-794-02) dies immediately.
  • Telepathy: Anyone within 1400 meters of the shipwreck is compelled to enter it.

SCP-795 - Reality-Bending Cat

https://static.tvtropes.org/pmwiki/pub/images/cat_45.jpg
Junior in a pet cage.
SCP-795 is a large, black, long-haired domestic cat of indeterminate breed given the name "Junior" before official discovery. Junior is known to exhibit two major anomalous abilities: he can change the physical form of any living creature he is able to observe within a range of 30m, and he can make telepathic suggestions to humans within the above range of effect. Junior can also transfer his abilities to other cats within his abilities' range of effect, but the effects are temporary on other cats, and will dissipate within three hours of separation from Junior.
  • 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.
  • Cats Are Mean: Played with. He's only mean to people he considers unfriendly or dangerous; he'll play with people he does like (after turning them into cats).
    • Although it's played 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.
  • Forced Transformation: He turns creatures into prey animals if he thinks they're dangerous or enemies; luckily, it wears off an hour after leaving his presence.
  • 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-796 - River Cat

SCP-796 is a condition where affected individuals begin to perceive a large feline entity in their peripheral vision. While the majority of subjects have described the entity as unusually large and dark-coloured, separate accounts of its shape, size, and overall body structure have been inconsistent. Subjects affected by 796 will often experience a strong sense of paranoia and dread, largely assumed to be a result of the entity's consistent presence. Visual hallucinations experienced by affected subjects notably correspond with manifestations of 796's physical effects. All affected individuals will experience an event that will place them in mortal danger within a month of first experiencing 796's effects.
  • Hidden Harasser: SCP-796 stalks one specific person at a time. It is completely visible to that person, but is not seen by most other people. People who are very perceptive or have psychic abilities may be able to spot it.

SCP-797 is an ovaloid object attracted to dying or freshly deceased humans. 797 is almost always seen with SCP-797-01, a collection of human flesh accumulated from various cadavers. 797 will use its collection of dead material to fashion itself a crude body, after which the object will attempt to interact with any living human entering its containment cell.

SCP-798 - Cortex Rat

SCP-798 is an adult gray/beige rat that has been seen to engage in behaviors usually associated with corvids or higher mammals. Among these behaviors are self-awareness, problem-solving skills, and the limited use of tools, suggesting the rat possesses heightened intelligence. 798 also possesses the ability to influence other animals from a distance, and is able to outright control them if allowed to establish physical contact. Recent tests imply that 798 demonstrates different behaviours when interacting with other rats, driving them to a murderous, primal rage by its mere presence.

SCP-799 - Carnivorous Blanket

SCP-799 is a species of organism that varies in size, shape, and superficial appearance per instance, but they always retain the appearance of a knit or woven item of bedding, made from an unfamiliar but very soft natural fiber. 799 are living organisms primarily hypothesized to be fungal in origin. They are usually torpid and incapable of movement, drawing the little nutrition they need from the organic detritus in household dust. If forced to go for long periods without sufficient exposure to dust, 799 is capable of metamorphosing into a predatory form, growing a large mouth filled with teeth and biting of chunks of warm-blooded animals who wrap themselves with it.
