Test Subject: A male tabby kitten with the same apparent age as SCP-247.
Control Test A: Subject played with the control in the manner expected of kittens.
Control Test B: Subject climbed a tree and attempted to hide itself from the control, displaying visible signs of terror.
Results (test i): Subject approached SCP-247 and mewed. SCP-247 responded in kind and played with the tabby kitten. The resulting footage is extremely odd; at one point SCP-247 lifts the subject (which appears to be the same size as SCP-247) with a single forepaw, while at another point SCP-247 lifts the subject with its mouth, clearly showing that its mouth is much larger than it appears to be. The leading researcher characterized this as adorable but remarked that it gave him β€œa headache.” Due to a faulty recorder, this test had to be repeated.
Results (test ii): Subject approached SCP-247 as above. SCP-247 made a deep purring sound, analogous to a growl. Subject reacted as in control test B.
Notes: This seems to indicate 247 has some degree of conscious control over its apparent appearance. - Researcher Sβ–ˆβ–ˆβ–ˆβ–ˆ
Experiment Log 247a-03
Date: β–ˆβ–ˆ/β–ˆβ–ˆ/2010
Test Subject: An adult male deer, a normal prey animal for a Bengal Tiger. (Control B and SCP-247 were not fed for 3 days prior to this experiment.)
Control Test A: Subject grazed. Control fell asleep two minutes into the experiment.
Control Test B: Control attacked, killed and devoured subject, which behaved normally for a deer trapped in an enclosed space with a large predator.
Results: Subject began grazing as in control test A. SCP-247 approached it calmly and killed it with a single bite to the neck, then proceeded to devour the subject. (Test was repeated without SCP-247 being forced to fast. SCP-247 completely ignored the subject for over a day before apparently becoming hungry and killing it, again with a single bite to the neck.)
Notes: SCP-247 seems to prefer humans, both as food and for entertainment. Other prey animals presented to SCP-247 were all killed in a single strike, while humans are invariably allowed to pet the SCP for some time before being killed and are sometimes mauled and β€˜played’ with the way a cat will play with a mouse. Furthermore, the SCP has killed every human it has had the opportunity to kill, regardless of hunger. - Researcher Sβ–ˆβ–ˆβ–ˆβ–ˆ
Experiment Log 247a-08
Date: β–ˆβ–ˆ/β–ˆβ–ˆ/2010
Test Subject: An adult female chimpanzee.
Control Test A: Subject and control ignored one another.
Control Test B: Subject retreated to a tree, showing some signs of unease. Control displayed some curiosity towards the subject but did not attack.
Results: Subject approached SCP-247, made noises identified as signs of affection, and began to groom SCP-247. SCP-247 allowed the subject to groom it for over an hour, then messily killed and devoured it.
Notes: This seems to be its typical reaction to unfamiliar prey animals. It seems to prefer to prey on apes with advanced social behaviour. Experiments with gorillas and other social apes have shown similar results. Essentially, SCP-247 is a large predator that has somehow adapted to take advantage of the largest available food source β€” humans. We should investigate all future reports of man-eating tigers in case there are more of these things. - Researcher Sβ–ˆβ–ˆβ–ˆβ–ˆ
Experiment Log 247a-12
Date: β–ˆβ–ˆ/β–ˆβ–ˆ/2010
Test Subject: An adult female grizzly bear.
Control Test A: Control fled up a tree in terror. Subject ignored it.
Control Test B: Subject and control acted nervously and gave one another as large a berth as possible.
Results: Initially subject and SCP-247 ignored one another. At one point subject came very close to SCP-247, resulting in SCP-247 giving a warning growl. Subject responded with hostility. Test aborted due to possible harm to SCP-247; subject tranquilized by Foundation personnel and subsequently killed by SCP-247.
Notes: Future tests involving animals potentially capable of killing or injuring a Bengal Tiger are cancelled. - Researcher Sβ–ˆβ–ˆβ–ˆβ–ˆ
Experiment Log 247a-13
Date: β–ˆβ–ˆ/β–ˆβ–ˆ/2010
Test Subject: An adult female Bengal Tiger
Control Test A: Control fled up a tree in terror. Subject ignored it.
Control Test B: Subject and control greeted one another, established the order of social dominance, then both fell asleep.
Results: Identical to control test B.
Notes: Interestingly, SCP-247 was the beta animal in this interaction. - Researcher Sβ–ˆβ–ˆβ–ˆβ–ˆ
Experiment Log 247a-14
Date: β–ˆβ–ˆ/β–ˆβ–ˆ/2010
Test Subject: An adult male Bengal Tiger
Control Test A: Control fled up a tree in terror. Subject ignored it.
Control Test B: Omitted, record of normal Bengal tiger mating behaviour substituted.
Results: As expected based on control B. [DATA EXPUNGED].
Notes: Researcher Sβ–ˆβ–ˆβ–ˆβ–ˆ has been removed from this project for lax security in his experiments, although in light of his injuries, further disciplinary measures have been deemed unnecessary. [DATA EXPUNGED], which seems to have benefited from a form of β€˜hybrid vigor’, has been designated SCP-247-1. Considering that SCP-247 is likely to have bred naturally in the wild, Mobile Task Force Iota-5 ("Tiger Bait") has been formed and assigned to hunt down and contain or destroy all incidences of the hybrid SCP-247-1. - O5-β–ˆ

[ Title: SCP-252 is a sub-species of Dosidicus gigas.; Genre: Scientific; Tags: 3rdperson; Style: Dark ]
***
Item #: SCP-252
Object Class: Euclid Safe
Special Containment Procedures: SCP-252 is to be contained in a 150Β m3 aquarium, reinforced with high tensile steel plating. Guards are to be specially trained in water-borne combat techniques and armed with model-B74H harpoon rifles with high-capacity electrical discharge shafts. The tank is fitted with 15 remotely-activated depth charges, which are to be detonated simultaneously if a containment breach is imminent A breeding pair is maintained under the direction of marine biologist Dr. β–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆ. Personnel should not approach the containment tank unless they have been previously prepared for the anomalous effects of the animals.
Additional specimens of SCP-252 may exist in the wild. Due to their destructive capabilities, capture is deemed a high priority. Given the difficulties inherent in the size of specimens, termination is authorized if a breach of secrecy is imminent. Current specimens are considered sufficient and further acquisitions are not a priority. Containment of information regarding encounters will consist of Standard Cover Story 53 "Drunken Sailor" and administration of amnestics as necessary.
Description: SCP-252 is a sub-species of Dosidicus gigas. Mature specimens are noticeably smaller than average, reaching no more than 1Β m in length and weighing a maximum of 40Β kg. Dissection shows the absence of an ink sac and an increased density of chromatophores (approx. 20 times the normal adult average).
Behavior is identical in most ways to mundane specimens, except when hunting or threatened. When a member of SCP-252 detects prey, they exhibit aggressive behavior and move towards the target at maximum speed while rapidly cycling their chromatophores. This color shifting has a hypnotic effect on prey animals that make visual contact, causing them to cease all defensive behavior and attempts to flee until grappled.
When threatened by a predator or otherwise agitated, SCP-252 rapidly metamorphs into an unidentified aquatic life form of extreme size with an indeterminate physiology and extremely destructive demeanor. Physical attributes in this state are in a constant state of change. Size fluctuates between 50 and 75 meters in length with no fewer than 50 and occasionally as many as 200 appendages of various natures. Appendages shift constantly between suckered tentacles averaging 5Β m in length, insectoid limbs terminating in barbed pincers, and humanoid arms and legs ending in sharpened talons. Details and positions of appendages on the body also vary randomly, with the only constant being a cluster of tentacles around the head obscuring the mouth area. It is not currently known how this rapid growth is achieved. Due to the potential for a containment breach no research on the matter is currently authorized. All animal life excluding other SCP-252 and mundane squid species will attempt to escape the vicinity by the most direct route possible. This fear response can cause the targets to harm themselves as they flee into hazardous conditions or ram repeatedly into container walls. Roughly 95% of subjects encountering an enraged SCP-252 develop a phobia of cephalopods. It is not known if this is an additional anomalous effect or a normal behavioral reaction to traumatic experiences.
Upon review of security footage during containment, Dr. β–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆ has determined that SCP-252's "metamorphosis" is in fact an advanced hallucination induced by the shifting pattern of chromatophores. These hallucinations cause the victim to see SCP-252 as a titanic sea creature with an excessively large number of tentacles. Specific details vary greatly from subject to subject, but the hallucinatory creature consistently presents as a greatly exaggerated cephalopod with tentacles clustered around the mouth area, additional appendages with talons or pincers, and the general impression that all features are fluid and randomly shifting. Subjects removed from visual contact with SCP-252 will remain convinced that their hallucinations were a real "sea monster" and will attempt to rationalize any logical contradictions inherent in their delusion, such as a 100Β m monster swimming in a 10Β m enclosed tank. This rationalization and the lingering phobia is thought to be a form of post-hypnotic suggestion.
Subjects viewing video of agitated SCP-252 who have never been exposed directly experience a much less severe fear reaction and are able to perceive the squid despite the hallucinations. Subjects describe the illusory monster as "fake-looking" and "nonsensical" but still find it moderately frightening. After second-hand exposure, subjects develop a partial immunity to the full effects of direct exposure. Repeated direct contact after "inoculation" by video further lessens the effects. Acclimatized subjects can develop a complete immunity to the fear effect and experience only the vaguest awareness of the hallucinations.
Addendum: SCP-252 came to Foundation attention after numerous reports of "sea monster" sightings by commercial fishermen off the coast of β–ˆβ–ˆβ–ˆβ–ˆβ–ˆ. Agent β–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆ secured a specimen at greater than usual personal danger. Commendation for performance above and beyond the call of duty recommended. Agent β–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆ allowed himself to be exposed to SCP-252's effects during first contact. Initial containment procedures were based on his reports of the specimen's size and physical capabilities, resulting in an excessive expenditure of resources. Disciplinary action recommended, pending oversight review.

[ Title: SCP-253 is a cluster of undifferentiated human cells, matching the physiological traits of cancer.; Genre: Scientific; Tags: 3rdperson; Style: Dark ]
***
Item #: SCP-253
Object Class: Euclid
Special Containment Procedures: At this time, SCP-253 poses a substantial threat to humanity. SCP-253 is to be kept under Biosafety Level-4 protocols at all times. All research is to be conducted at a site where incineration and irradiation protocols can be swiftly enacted, that is geographically isolated, and does not possess a diverse biosphere. The sterilization protocols shall be enacted following the occurrence of any event on this list:
Communications blackout lasting longer than forty-eight (48) hours.
Power disruption lasting longer than one (1) minute during any active experiments involving SCP-253.
Abnormal rise in average temperatures beyond a change of 6 degrees Celsius (11 degrees Fahrenheit) or rise in humidity levels to 90% relative humidity.
Manifestations of unusual electromagnetic phenomena during testing of SCP-253.
At the conclusion of testing, any subjects exposed to SCP-253 are to be disposed of, and their remains are subject to the sterilization protocol.
Any researcher leaving the facility is to undergo two weeks of mandatory chemotherapy, followed by a 15-day quarantine.
Description: SCP-253 is a cluster of undifferentiated human cells, matching the physiological traits of cancer. As per cancerous cells, cultured samples of SCP-253 will grow indefinitely if given an adequate source of nutrition. SCP-253 is contagious, able to pass from human to human, as well as to some animal species. SCP-253 is not an airborne contagion, but physical contact with surface neoplasms on infected subjects will spread the plague.
The first sign of SCP-253 infection is the emergence of skin lesions, typically dime-sized (2Β cm in diameter) in groups of three to five, at the site of infection. Within twelve (12) hours after the appearance of the lesions, MRI scans show the development of neoplasms within the brain. At this time, the neoplasms do not induce neurological symptoms.
Over the next twenty-four to forty-eight (24 to 48) hours, numerous skin lesions start to emerge and grow in size. These lesions often induce substantial swelling in surrounding tissue, which can be quite painful for the subject. Often, the pain, if left untreated, leaves many subjects unable to move. Towards the end of the forty-eight (48) hour period, neoplasms start to emerge in the lymphatic system and neurological symptoms start to manifest.
The neurological symptoms of SCP-253 are different for each patient, depending on which part of the brain the invasive cells have contaminated, with one exception. Each human patient heretofore exposed to SCP-253 has felt a complete cessation of pain forty-seven to forty-nine (47 to 49) hours after infection. Other neurological symptoms include:
Inability to focus attention
Disorganized speech
Memory loss
Hallucinations
Euphoria
Megalomania
Inappropriate emotional responses
Sociopathy
Catatonia
The neoplasms do not seem to respond to radiation, and chemotherapy with high-dose mitoxantrone, irinotecan, and dacarbazine has only minimal effects. Chemotherapy was observed to kill some cells and markedly slow the growth of others, and therefore might be useful for post-exposure prophylaxis, but is ineffective in established disease.
If the mass of cancerous cells within a population does not reach a biomass threshold of approximately one-thousand four-hundred kilograms (1400Β kg/3100 lbs), the cells will overwhelm the host within five (5) days, resulting in death. If not transferred to a new host, the cancer cells will consume any remaining usable biomass of the host's corpse before finally running out of resources and dying.
However, if the mass of cancer cells within a population reaches the threshold, electromagnetic phenomena will start to manifest. The sources of these phenomena appear to be the infected hosts, but the mechanism of the EM manipulation is not understood at this time.
Furthermore, it appears the EM emanations facilitate some sort of communication between the hosts. Coordinated in some fashion by the neoplasms, the hosts start to act as one entity spread through many bodies. The intelligence of this entity is initially animalistic and reactive. As the intelligence of the gestalt entity is believed to be based on the remaining brain tissue within the hosts, it is hypothesized that the entity may be able to achieve human-like intelligence. The events from Incident I.J77.82 appear to support this hypothesis, and research suggests that some of the more unsettling things seen at β–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆβ–ˆ Hospital are manifestations of this intellect.
Until suitable methods can be created to jam the EM transmissions of the end-stage infection entity, and until efficacious treatment alternatives for the diseases known as cancer enters common usage, the utmost care must be taken with samples of SCP-253.
Addenda:
253a: Proposal that SCP-253 be classified as Euclid is pending review of Incident I.J77.82 by the Overseers.
253b: SCP-253 has been given provisional Euclid classification. Final report on Incident I.J77.82 has been released. Research into the events of Incident I.J77.82 has been approved.
253c: Research involving approaching the threshold biomass in human subjects has been denied. Decision on request to test threshold biomass in cultured samples pending.
253d: Use of SCP-500 in experiments with SCP-253 has been denied.
253e: Use of SCP-427 in experiments with SCP-253 have been approved. Early results are not encouraging. Despite success using 427 to treat other forms of cancer, in this instance, 427 appears to induce accelerated growth in both tumorous growths as well as in the patient. Subjects were terminated as they neared the critical threshold for use with 427. Request to take patients beyond the critical threshold is pending.
