Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-xxxx is to be contained in a standard humanoid containment cell. All furniture within the cell is to be constructed of corrosion-resistant materials. Meals (as specified by the on-site dietitian) are to be provided daily via delivery drone. Additional amenities, including leisure books and snack food, may be provided for good behavior as considered appropriate by the research team assigned to SCP-xxxx.

SCP-xxxx is to receive daily academic instruction for four hours each weekday, from a rotating roster of six Level-2 research personnel assigned to the case as short-term tutors. Curriculum and individual work assignments are to follow national grade level standards, with supplementary elective activities (e.g., music, creative writing, figure drawing) offered at researcher discretion. College-level material may be offered when SCP-xxxx exhibits willingness to proceed with higher level education.

A Foundation psychologist is to meet with SCP-xxxx once a week at minimum, to gauge personal development and trauma recovery progress. Outside of these meetings, access to SCP-xxxx's containment cell requires Level-3 authorization and written permission from the lead researcher of the SCP-xxxx project.

Protective clothing must be worn while within SCP-xxxx's containment area. A set of corrosion-resistant suits and masks has been placed in a cabinet near the entrance to SCP-xxxx's cell.

Description: SCP-xxxx is a human male of Asian descent, with apparent age at 17 years, standing 182cm in height. SCP-xxxx demonstrates a number of atypical behaviors, including preferring to sleep at a desk rather than a bed, and spending most of its time stationed in a corner of its cell reading while curled into a fetal position.

SCP-xxxx possesses a bodily composition similar to that of nonanomalous humans, with two primary anomalous traits: SCP-xxxx's body does not appear to age, and various bodily fluids produced by SCP-xxxx contain low amounts of acidic substances. When SCP-xxxx is frightened or injured by a visible stimulus, it will reflexively spray highly concentrated gastric acid1 from its mouth in the direction of said stimulus.

SCP-xxxx has been noted to possess a high level of environmental sensitivity and will often exhibit symptoms of anxiety; these traits lead to a high likelihood of everyday occurrences triggering its anomalous property. However, SCP-xxxx has frequently been observed attempting to redirect the acid it produces, to avoid harming other people in the vicinity.

The farthest recorded distance of acid sprayed by SCP-xxxx is 3 meters. The acid itself, while chemically identical to non-anomalous gastric acid, is strong enough to corrode most organic and inorganic matter. SCP-xxxx itself reports suffering pain when its anomaly is triggered, stating that the stomach and throat pain makes it feel "miserable". SCP-xxxx also has claimed many times that it hates its unusual nature.

Regular communication and psychotherapy are believed to improve SCP-xxxx's cooperation with Foundation research staff, though SCP-xxxx typically reacts with little enthusiasm to attempts to build conversational rapport. Currently, the primary requests made by SCP-xxxx for containment amenities have all been related to finishing its education; SCP-xxxx seems to respect its tutors the most compared to other staff it interacts with.

Addendum—Discovery: Upon initial Foundation acquisition, SCP-xxxx identified itself as an international (foreign exchange) student enrolled at ██████ High School of Melbourne, Australia. At the time, SCP-xxxx had also attended █ other high schools previously, never remaining at one site for more than three months. School behavioral records indicated that while a devoted student, SCP-xxxx found difficulty making friends and was frequently a target of bullying.

SCP-xxxx's history of school transfers was noted to correspond exactly to frequent incident reports of unusual injury occurring in several different Melbourne high schools from ██/██/████ to ██/██/████. All cases involved student victims with bodily injuries exhibiting corrosion of various degrees. The most recent incident involved the death of a female student, with the local media falsely attributing the accident to have been the result of an emotional dispute between SCP-xxxx and the victim.

During the location transfer from his host family's residence to a nearby Foundation site, SCP-xxxx was noticeably taciturn and refused to respond verbally to communication. The single exception was thanking personnel when provided food to eat during the journey.

Addendum—Interview logs: Due to SCP-xxxx's emotional state affecting the manifestation of its anomaly, regular interviews were implemented in lieu of experimental testing. SCP-xxxx is noted to prefer conversing in English, though that is not its native language.


As of ██/██/████, SCP-xxxx is rapidly becoming more fluent in English, and has completed study material for several university-tier science courses. Discussion is underway regarding allowing SCP-xxxx limited access to Foundation research pertaining to anomalous biology, in the hopes of it finding a means to neutralize its harmful effects.
