Item #: SCP-8149
Object Class: Euclid
Special Containment Procedures:
SCP-8149 is currently uncontainable due to its ability to phase through all materials except concrete. Surveillance and monitoring equipment have been installed in a 2-kilometer radius around its original point of manifestation at Vasaros g. 5, Vilnius, Lithuania (a now-abandoned psychiatric hospital). All structures within this radius have been retrofitted with reinforced concrete walls to deter SCP-8149’s movements.
Inhabitants of the area are to be relocated, and a public cover story involving dangerous structural instabilities in the region has been disseminated. SCP-8149 sightings must be reported to Mobile Task Force Epsilon-8 (“Concrete Guardians”) for further tracking and analysis.
All experimental projects conducted at Vasaros g. 5 are suspended indefinitely, and records related to said experiments are under review by the Foundation for their connection to SCP-8149.
Description:
SCP-8149 is a humanoid entity approximately 130 cm tall. Its body exhibits an anomalous morphology, with a 1:4 body-to-legs ratio, giving it an unnaturally elongated lower body. SCP-8149 lacks hands, with its arms ending in rounded, stump-like appendages.
The entity manifests exclusively during nighttime hours, between 22:00 and 04:00 local time. It appears to phase effortlessly through all known materials except concrete, suggesting an unknown interaction between its molecular structure and the properties of concrete.
SCP-8149 is typically observed walking aimlessly or standing motionless for extended periods. It does not display overt hostility toward living organisms, but prolonged exposure to SCP-8149 has been linked to psychological distress, including paranoia, insomnia, and vivid hallucinations.
Efforts to capture SCP-8149 using bait or traps have proven ineffective. SCP-8149 has demonstrated an instinctual avoidance of fully concrete-enclosed spaces, suggesting a possible aversion or vulnerability.
Discovery:
SCP-8149 first manifested on 1990, February 14 following an experiment conducted at the abandoned psychiatric hospital located at Vasaros g. 5, Vilnius. The experiment, reportedly overseen by personnel unaffiliated with the SCP Foundation, involved an attempt to induce psychokinetic phenomena in test subjects. During the procedure, an unexpected surge of electromagnetic energy was detected, followed by the sudden appearance of SCP-8149.
Subsequent investigations into the hospital’s records uncovered evidence suggesting that SCP-8149 is the altered remains of a former resident named John Bread, who was admitted to the hospital in 1987 for severe schizophrenia and paranoid delusions. Staff notes describe John as claiming to “see creatures no one else could” and being obsessed with the concept of walking through walls. John was reportedly a participant in the psychokinetic experiment that caused SCP-8149’s manifestation.
Initial containment efforts were hindered by SCP-8149’s phasing abilities. The Foundation took control of the site, and surviving experiment participants were amnesticized and released. All anomalous equipment at the site was confiscated for analysis.
Addendum 8149-1:
Incident Report 8149-01
On 2016, July 4, SCP-8149 breached a Foundation observation post located 1.5 kilometers from Vasaros g. 5. Personnel reported experiencing disembodied whispers and flashes of distorted humanoid figures in their peripheral vision during the breach. One staff member was found in a catatonic state following the encounter. Psychological evaluations indicate severe trauma resembling symptoms of sleep paralysis.

Concrete reinforcements were installed at the observation post following the incident. SCP-8149 has not re-entered the location since.
Addendum 8149-2:
Research Notes
Analysis of SCP-8149’s phasing ability suggests a non-Euclidean interaction with space-time. The entity’s aversion to concrete remains unexplained, though hypotheses include:
1. Concrete’s unique molecular composition disrupts SCP-8149’s phase state.
2. SCP-8149 originated from an environment where concrete did not exist, resulting in an innate aversion.
Further testing in controlled environments is pending approval.
Addendum 8149-3:
Exploration Log 8149-A
A remote-controlled drone was deployed into the basement of Vasaros g. 5, where SCP-8149 was first observed. The drone captured footage of a sealed chamber with a scorched floor and scattered fragments of shattered equipment. On the walls, phrases written in Lithuanian appeared to read:
• “It sees us.”
• “We created it, but it is not ours.”
• “Do not follow the legs.”
The implications of these phrases remain under investigation.

Hi, I’m Stasys
I have been keen on the scp foundation for a while, but I have just now thought of joining the wiki, I already have an entity in mind. I will write it in the next month
https://scp-wiki.wikidot.com/forum/t-17011361/help (included the full draft of their coldpost, thread summary "My creation just got deleted and I would like to know what I can make better. I’m pretty new. My idea is a creature that appeared out of an experiment in a mental asylum. It has long legs and no arms")
