Item #: SCP-XXXX
Object Class: Euclid-provisi
Special Containment Procedures: SCP-XXXX is to be housed in a well-furnished chamber equipped with standard audio and video surveillance tools within Site-17, as well as provided books and electronics for the purpose of entertainment. Per the orders of Doctor Alvin Greaves, SCP-XXXX is to be addressed as Dennis and treated respectfully by all staff. The approval of at least 2 personnel with Level 4 clearance or higher is required for authorized removal of SCP-XXXX from its designated chamber. Although not necessary for SCP-XXXX to consume conventional food items, it often requests and may be granted Dum Dums brand lollipops and Life Savers brand mints if behavior and cooperation remains satisfactory.
Once per day, at precisely 7:05 a.m. UTC, 1 heavily anaesthetized D-Class Personnel approved for termination (an instance of SCP-1680 is recommended) is to be introduced into SCP-XXXX's chamber. On-duty security officers monitoring the surveillance feed are to oversee the feeding process and confirm that the current understanding of the craving phase remains consistent with the behavior of SCP-XXXX. Authorization for testing SCP-XXXX's abilities and behavior while in the craving phase has been granted exclusively to Dr. Greaves by the O5 Council on account of his expertise in manipulative cajolery and psychological profiling.
Should SCP-XXXX remain in the craving phase for a prolonged period for any reason, SCP-999 is to be supplied to it for the purpose of aiding in emotional recovery upon its conclusion.
Description: SCP-XXXX is an athletic Caucasian male of unknown origin, appearing to be 18 years of age, and has shown no signs of growing older or experiencing a change in body complexion despite being in Foundation custody since 2016. All available public records have yielded no prior documentation of its existence. SCP-XXXX is normally complacent and exceptionally jovial around foundation staff, displaying a fondness for Dr. Greaves. As of its acquisition by the Foundation, it has only been able to recall semantic memories from its educational experiences and the fact that its parents gave it the first name Dennis.
When the period of anomalous activity colloquially dubbed "the craving phase" is not in effect, SCP-XXXX exhibits no immediately apparent anomalous traits besides a complete disinterest in eating or drinking, claiming that it is never hungry or thirsty. As such, no waste materials are excreted. Examination of the digestive tract reveals that all organs of the digestive system below the esophagus are inert, failing to produce or absorb any fluids. The urinary system displays an apposite stasis. Contrarily, blood sample analysis has shown that a healthy and constant concentration of nutrients, vitamins, and minerals is present at all times, as well as an unusually high concentration of stem cells. The source of these components is unclear, bearing the implication that SCP-XXXX has an unlimited supply of energy to draw from.
An additional anomalous property of SCP-XXXX's blood is evident through close observation: no foreign liquid, gaseous, or solid particle can disseminate into its volume by any means, inside or outside of SCP-XXXX's circulatory system; they are instead repelled to its surface, preventing the blood cells and stem cells within it from being harmed or otherwise influenced by external forces. It is not fully understood how SCP-XXXX respires under these conditions, yet it has been demonstrated that it does require oxygen intake to survive outside of the craving phase and consistently exhales carbon dioxide and water vapor. Similarly, all electricity channeled toward the blood is redirected toward the most available conductive surface. When exposed to a source of extreme heat or radiation, an exterior layer of the blood instantly coagulates1 to protect the cells in the main volume of blood. The platelets that compose this layer seem to possess the ability to absorb impossibly high quantities of kinetic energy and radiant particles, and the Foundation's efforts have yet to discover a means of damaging them. Interestingly, the impervious nature of SCP-XXXX's blood is not reflected in the tissue, which holds no anomalous traits and is easily damaged. This poses a severe health concern to SCP-XXXX since hemophilia is inherent to the anomalous nature of SCP-XXXX's blood.
At exactly 7:06 a.m. UTC every 24 hours, SCP-XXXX enters the craving phase, indicated by a swipe of the tongue across the upper lip from right to left and a dilation of the pupils. In this phase, SCP-XXXX becomes unresponsive to attempts at communication2 and anomalously procures massively increased physical ability. Dr. Greaves has confirmed that 10 times its normal strength and durability are achieved.
Entering the craving phase invariably causes SCP-XXXX to seek and pursue living, sentient creatures, with humans as the preferred target3. Upon capturing a target, SCP-XXXX will begin to tear flesh from the victim and swallow portions of the body until it has ingested all of the solid remains. Attempts to sedate or immobilize SCP-XXXX with psychoactive drugs, toxins, and even SCP-061 have proven ineffective. The organic matter that enters SCP-XXXX appears to vanish completely, as it has never experienced a detectable change in mass.
The craving phase will only end when SCP-XXXX has consumed an entire human body, at which point all of the anomalous activity it brought about will cease. For every 24 hours that this criterion is not met, another human consumption is required for the expiration of the craving phase and SCP-XXXX's physical capacity will once again be magnified tenfold, making the prospect of indefinite containment of SCP-XXXX without a supply of living humans unreasonable, as it could potentially surpass the destructive power of Keter-class anomalies.
While the craving phase is in effect, SCP-XXXX's blood accumulates yet another anomalous property: all blood that is forcibly separated from SCP-4195's body gravitates toward the main volume of blood. It is possible for blood to be extracted and contained in a separate location(s), but the attraction between bodies of blood becomes stronger with each passing day of the craving phase, presumably in correlation to SCP-XXXX's power.
SCP-XXXX's regenerative abilities during the craving phase are not restricted to closing wounds, but can regrow limbs and vital organs, including the brain and heart. As a result, injuries that would normally be fatal can be recovered from, given time. This effectively makes SCP-XXXX an immortal entity during the craving phase, with its incorruptible blood granting it limitless energy reserves to fuel and regenerate tissues, even when reduced to nothing except blood. The rate of regeneration is additionally accelerated by a factor of 10 with each day that the craving phase has lasted, although the manner of tissue restoration that SCP-XXXX is subject to cannot be meaningfully compared to normal human regenerative patterns due to the lack of hemorrhaging and scabbing involved, among other factors.
If the craving phase is not in effect, SCP-XXXX is entirely capable of perishing, as found in Incident XXXX-A. However, upon the time of activation for the craving phase, SCP-XXXX's blood will proceed to exhibit its scheduled anomalous behavior, gradually spawning flesh to reanimate it in a fresh body.
Hume readings of SCP-XXXX's blood fluctuate drastically during the craving phase. [DATA EXPUNGED]
SCP-XXXX claims that it has no memory of the actions it performs during the craving phase. By its accounts, its consciousness is transported to what it perceives to be a lake of fire, with excruciating pain being perpetually inflicted upon it and other nondescript beings within the swathe of flames in the time that it is not in control of its body. SCP-XXXX also reports this phenomenon occurring to it while it is dead. Dr. Greaves has verified that SCP-XXXX's brainwave patterns are dramatically altered once the craving phase has begun, interestingly resembling a state of sleep paralysis.
Addendum XXXX-01: SCP-XXXX was initially discovered and reported ██/██/2016 as an unidentified decedent approximately 115 meters outside of Area-02, having fallen from an estimated height of 45 meters by unknown means, casually dressed. A recovery team was sent to retrieve the body for autopsy, which yielded inconclusive results. Following Incident XXXX-A, Dr. Greaves appealed for authorization to question and evaluate SCP-XXXX, relocating it to Site-17.
Incident XXXX-A: At 7:06 a.m. UTC on the date of ██/██/2016, as SCP-XXXX's autopsy was being performed at Area-02, the first known craving phase took effect. The blood that had been spilled at the site of impact amassed into a single aggregation, which began to generate tissue. The remaining blood in SCP-XXXX's cadaver flowed towards the newly forming body only to be stopped by the wall of the autopsy theater. Security personnel were notified of this anomalous activity and the aggregation of blood producing new flesh was identified as an anomaly. A standard humanoid containment chamber was prepared for SCP-XXXX and the biomass was relocated to the facility, with researchers monitoring its growth until it was completely reborn after a 60-hour reconstruction process. An attempt to engage in conversation was made to no avail. The power amplifications accumulated during the recovery period enabled SCP-XXXX to dismantle the entrance door of the containment chamber in a single blow4, sending Foundation staff into panic. A squadron of 6 armed security officers quickly confronted SCP-XXXX, only to have their tracheae avulsed before a round was even fired. None of the group members survived the attack. SCP-XXXX then hastily devoured 3 of the corpses before reinforcements could arrive, ending the craving phase. Exiting the craving phase left SCP-XXXX in a state of severe emotional distress, having spent so much time in constant suffering. Following inspection and relocation to a heavy containment facility, Foundation personnel deemed SCP-XXXX no longer an immediate threat. After SCP-XXXX's anomalous properties were ascertained, special containment procedures were established.
Exposure to SCP-999 paired with intimate consolation is currently the only known viable remedy for the psychological trauma caused by an instance of the craving phase lasting for a significant duration. Dr. Greaves has speculated that SCP-294 may be able to produce beverages with a profound psychological effect and serve as an additional countermeasure, but this has yet to be tested.
Addendum XXXX-02: Dr. Greaves has suggested SCP-XXXX be reclassified as Thaumiel and utilized as a means of neutralizing SCP-4910 and/or SCP-682. Pending review of the O5 Council and Ethics Committee. Should this measure be approved, a specialized task force is to be assigned to SCP-XXXX under the direction of Dr. Greaves.
Addendum XXXX-03: Tried feeding clones of D-Class personnel from SCP-038 to SCP-XXXX. They are acknowledged as living beings and appropriately consumed, but apparently they don't qualify as real humans. Damn shame. I guess some clones are worth more than others. Or maybe all D-Class are clones. Something to think about, eh? In other news, to those of you asking about the possibility of continuously removing flesh from SCP-XXXX to supply individuals in need with meat, the answer is no. Besides the highly questionable (to put it lightly) ethics of such a practice, it would take an enormous amount of force just to penetrate his skin once the craving phase had persisted long enough for the rate of regeneration to render the operation viable. Stop trying to pitch the idea to me. I'm getting bored of hearing it. - Dr. Greaves
