Scariest SCPs Ever Found

The SCP Foundation is an organization dedicated to protecting humanity. Not from wars or disease, but from supernatural entities and anomalies called SCPs! Though some are harmless, others are so terrifying that locking them away from the rest of the world is the only way to protect mankind from their existence. From killer creatures to cursed objects, the vaults of the Foundation are filled to the brim with nightmare-inducing entities. Let's take a tour of the most terrifying of them all.

SCP-173: The Sculpture

If you’re ever unfortunate enough to be left in a room with SCP-173, its utterly bizarre appearance might make you look twice. But whatever you do, don’t take your eyes off it.

Even though it’s made from a simple mix of reinforced steel, concrete, and spray paint, this SCP is somehow animate! Not only that, it displays a vicious resentment towards anything that moves, providing they’re not looking straight at it. Even a quick blink gives it the opportunity to rush forward and attack, meaning the last thing you’d ever see is that unnervingly painted face suddenly looming over you. But after seeing that thing up close, death would almost certainly be preferable!

SCP-087: The Stairwell

When you were a kid, was there anything more terrifying than walking down an unlit staircase? The steps felt like they went down forever, and you could have sworn there was something lurking in the dark. Your parents probably told you it was just your imagination, but the existence of SCP – 087 will make you wish they were right!

In the building of an undisclosed college campus, SCP-087 manifests as a never-ending, shadowy platform staircase. Test subjects sent down to explore the stairwell report that it goes down far beyond the structure of the building, or any geological surroundings.

However, they’re never alone in the darkness. Subjects have reported hearing the pleading cries of a young child echoing from the shadows around them. But no matter how far down they go, they’re never able to reach its source. In one final exploration, subjects documented their descent using a video camera, hoping to capture some evidence of the source on film. Instead, one still frame revealed the haunting face below peering out of the shadows at them.

It follows anyone who tries to descend, remaining just out of reach while shadowing their every move. Although some test subjects have re-emerged from the endless depths, others haven’t been so lucky. It’s unknown if they’re still alive down there, or if they’ve been lost to the haunting cries and infinite darkness of SCP-087 forever.

SCP-149: The Mosquito

The common mosquito is, arguably, the worst animal on the planet. The blood-sucking menace can transmit hundreds of diseases, killing countless people and leaving many others covered in infuriatingly itchy bite marks. But as terrible as they are, they’re nothing compared to SCP-149.

It’s an unnatural breed of mosquito that carries a truly repulsive retrovirus. While a regular mosquito might leave you with malaria, one bite from SCP-149 will warp your DNA and leave you riddled with hundreds, sometimes thousands of mosquito eggs! They typically line the sinuses or esophagus, resembling unimaginably creepy clusters of cysts. But the real horror show starts when they begin to hatch.

After just a few hours, the cysts burst revealing swathes of brand-new baby mosquitos, all of which clamber out of the nearest orifice. This means the mouth, nose and even eyes of the poor victim are chokingly overrun by the insidious swarm! The event is often fatal, and considering how horrendous having thousands of mosquitos climbing out of your face must feel, that’s probably a good thing!

SCP-049: The Plague Doctor

At first sight, you’d be forgiven for thinking SCP-049 was just someone messing around in a “Plague Doctor” Halloween costume, minus the spandex and pantyhose! But this creepy get up is part of its identity, quite literally! The thick, hide-like robes and beaked, bone-white mask grow out of its face and body, almost like a second skin!

But despite its monstrous exterior, SCP-049 acts surprisingly human. It speaks a comprehensive mix of languages including English and medieval French. And while it usually acts politely, it will turn terrifyingly hostile if it senses, what it calls, “The Pestilence”. Should it detect this mystery disease, SCP-049 will spare no opportunity to kill whoever is carrying it. But not with a gun, or even a knife, but with its skin!

The briefest of physical contact with SCP-049 causes a living creature to instantly drop dead, after which this doctor of death will demand to “cure” them. However, this doctor’s “cure” actually involves the gruesome reanimation of the corpse! In its zombified state, the creature is then bound to the will of SCP-049, allowing it to create an aggressive army of undead minions! Fortunately, it’s securely contained. But if the world is suddenly over-run by a zombie apocalypse, you know exactly who to blame!

SCP-1562: The Slide

Do you remember how awesome playground slides used to be? Before the world had ever heard of health and safety, you could slide down them at breakneck speeds with the guarantee of a scraped knee or two at the end. But not if you ever slid down SCP – 1562, because shockingly you’d never make it to the end!

The slide was requisitioned by the SCP Foundation after several children in its area went missing. They later discovered that anyone who slid down this metal death trap head-first inexplicably vanished a few inches before the end.

To find out where it led, they sent down test subjects with safety lines and radios to report back. They emerged in a small, cramped tunnel with no light, surrounded on all sides by rock and dirt. But while the radios worked, the lines were severed, meaning there was no way to get them back out.

Before the panic fully set in, they briefly squeezed their arms up to feel around the tunnel. Then, they reported they’d found something. It was a shoe; a very small, unmistakably child-sized shoe. To date, no one has been rescued from this unimaginably claustrophobic dimension, and with all testing reportedly suspended, there’s no light at the end of this tunnel.

SCP-2170: The Clown Vaccine

Having an irrational fear of clowns is no laughing matter. Their garishly bright smiles, over-painted features, and goofy laughs can completely paralyze people with panic! And if that description alone had you feeling slightly uncomfortable, be sure to stay away from Tonopah, Nevada. Because it’s here, in a hideously triggering motel, that the SCP-2170 are currently contained.

They’re memetic entities, which spawn during a kind of infected thought process. In that way, they live in your mind and feed off your thoughts, which in this case is triggered only in those who have a fear of clowns.

While they don’t actually resemble the freakish fools themselves, they constantly perch on the edge of the sufferer’s vision, whispering streams of ominous nonsense until they go mad! Eventually, prologued exposure to SCP-2170 results in crippling paranoia and hostility, before leading to their death. So, if the thought of oversized shoes and big red noses sets you on edge, maybe take Nevada off your list of places to visit!

SCP-303: The Doorman

Sometimes, it’s not what an anomaly can do, but what it looks like, that can paralyze you with fear. And the perfect case in point to prove that is SCP 303.

This emaciated humanoid haunts the shadowy corners of darkened windows, baring its most terrifying feature; that massive, grinning mouth. With no other discernible facial features, its oversized, humanoid teeth take up more than half of its head, accompanied only by a skin-crawling, wheezing noise.

Though the malicious sight has full grown men cowering in fear and crying for their mommies, SCP 303 never attacks. And if someone gathers the courage to try and view it without a pane of glass in the way, it quickly dematerializes. Though it reappears later, constantly haunting the doorways of unlucky humans, it’s never made any attempt to communicate. Instead, it chooses to eternally lurk in the shadows, scaring people witless with that monstrous mouth whenever it can.

SCP-3199: Humans, Refuted

During a blackout, the last thing you want to stumble across is the large, bow-legged bulk of SCP-3199. Standing at a gigantic 9.5 ft tall and weighing over 1,700 lbs, the huge body of this spine-chilling entity resembles a freshly plucked chicken with an impossibly human face. But, horrifyingly, it is!

Tests revealed that SCP-3199 is comprised of at least 6 types of DNA, including silkie chicken and human. This unnatural combination means that instead of hard bone, its spine consists of cartilage, allowing it to hellishly dislocate its neck and twist its head 340 degrees around! So, you can forget trying to sneak up on this thing from behind though god knows why you’d want to! Because despite its chicken genes, it’s a terrifyingly opportunistic predator.

When it comes into contact with living prey, it somehow dissolves their internal organs and bones, turning them into a liquid-filled skin sack. It then drags the pre-digested meal to its nest, where its hideous young slurp it up like a kind of sickening meat soup!

It can have multiple nests, some of which are filled with 800 lb hatchlings, meaning most of the adult’s time is spent hunting for their next meal! But when it does have the opportunity, it lays a new egg. Not by squatting, but by passing it through its digestive tract and out through its mouth, screaming excruciatingly the entire time!

SCP-096: The Crying Man

Some of these awful anomalies make you want to scrunch your eyes shut, cover your ears, and cry for your mommy. And if you want to avoid the wrath of SCP - 096, that’s exactly what you should do! Unnervingly nicknamed “The Crying Man”, this SCP is a pale, gangly, humanoid creature that has a face not even its mother could love. That’s because its jaw can open 4 times as long as an average human’s, giving it a void-like mouth that distends to the bottom of its neck.

This hideous feature is one that it’s acutely aware of, and it goes to great lengths to hide its face from any morbidly curious onlookers. But in the event that someone does catch a glimpse of its freaky façade, then all hell suddenly breaks loose. This long-limbed anomaly will desperately shield its face before letting out a stream of blood-curdling wails and screeches. After a heart-stopping minute, its distress turns into pure, unadulterated rage, and it’ll begin hunting after whoever saw its face.

According to Foundation reports, there’s no known material or method that can stop it advancing, even anti-tank weapons can’t put a dent in it! But finally, once this SCP finds its unfortunate victim, it destroys them with an ungodly ferocity. So much so, that when it’s finished, not a single trace of its victim’s body remains.

SCP-682: The Hard to Destroy Reptile

Just the idea of dunking a living thing into flesh-eating acid is enough to make most decent people feel uneasy. But in the case of SCP-682, I bet no-one would give a second thought to pulling that lever. Also known as the Hard to Destroy Reptile, this terrifyingly large and vastly intelligent creature has the unique ability to regenerate and shed different parts of its body.

With this miraculous ability, it can move and communicate with as much as 87% of its horrifying body either rotted or destroyed! Although it could provide a scientific goldmine of information, there’s one blood-curdling fact about the creature that has most researchers cowering in fear; It despises all life on Earth!

So, given the opportunity, SCP-682 will try to kill absolutely everything and anything in its path! It’s for this reason that the Foundation has tried, on multiple occasions, to destroy it. But despite being torn apart, blow to pieces, dropped in acid, and even forced to engage with other deadly SCPs, it cannot be neutralized. The complexity and speed of its regeneration process allows it to heal fatal wounds in a matter of seconds!

So, for the sake of humanity, it’s kept contained in that vat of previously mentioned flesh-eating acid. There, it’s forced to constantly regenerate, until its researchers find a way to destroy it, once and for all.

SCP-957: Bait

The way that some of these SCPs kill, maim, or devour their victims makes you wonder if they’re completely empty inside. However, that’s quite literally the case with SCP – 957. This thin, hollow, humanoid creature has a distorted torso that sports an unnaturally large tear, showing that its body is completely devoid of any internal organs.

Gut-wrenching as that is, the way it hunts down its victims is even more disturbing. Firstly, it seeks out a house occupied by a single human being. Before it can be restrained, it forces the victim into the hollow of its chest, which leads to its own pocket dimension. When the poor, unfortunate soul re-emerges hours later, it’s missing its eyes and its memory. Inexplicably, the individual is now convinced they have been blind all their life, and, more disturbingly, that SCP-957 is a close family member who they care for.

SCP-1471: The Application

The world we live in seems to have a mobile app for just about everything, including one that serves as a home for one of the most unnerving SCPs ever discovered.

Before it was erased from the web, the seemingly harmless application could be downloaded as the innocently named MalO ver1.0.0. The curious little app had no listed developer, enticing risk takers to download it and see what would happen. At first, none of the downloads seemed to work. But then, after about 6 hours, users started receiving messages with photos of places they had recently been, each containing the unfathomably perturbing SCP-1471-A.

The anomaly manifests as a large canid skull with long, matted hair. This hulking monster slowly begins to appear closer and closer in each image, almost as if it’s stalking its prey. But then, after 90 hours, individuals exposed to this anomaly will start to see SCP-1471-A wherever they look! Though it’ not aggressive, it will constantly lurk in their vision, never leaving them alone or giving them a moment’s rest! Could you imagine waking up in the middle of the night to see this thing watching over you?

SCP-2521: Unspeakable

Of all the terrifying SCPs I’ve described so far, there’s one that’s quite literally unspeakable. SCP-2521 is an ominous, humanoid creature that’s made up of strange black tentacles. It uses these, along with some reality shifting abilities, to phase itself through walls and envelope its prey before disappearing into the darkness.

Aside from this, not much is known about SCP-2521, because all records about it are kept as a series of pictograms and photographs. This is because it can track down and immediately consume any written information produced about it.

I hope you were amazed and not just utterly terrified at these scary SCPs! If you want to explore the topic further, you might want to read about the SCP Foundation explained. Thanks for reading.
