Item Number: SCP-XXXX

Object Class: Safe

Special Containment Procedure: SCP-XXXX is to be kept in a default anomalous human holding cell, 6 x 6 x 3 meters in size. SCP-XXXX is not to be moved unless authorized by a personnel of level 2 clearance or higher. While SCP-XXXX is docile and non-threatening, all personnel handling SCP-XXXX should wear full body hazmat suits that block any skin from sight, as to prevent SCP-XXXX from marking any personnel with SCP-XXXX-1.

As long as SCP-XXXX continues to show good behavior, it is to be given items potentially deemed "items of interest" by SCP-XXXX on a bi-weekly basis. Under no circumstances are personnel to attempt to remove SCP-XXXX's mask unless specifically authorized by Research Initiative XXXX Executive Head, Ryan Praken. If SCP-XXXX offers any personnel an item that had previously been marked by SCP-XXXX-1 and is no longer marked, said personnel is to accept the item and bring it directly to Research Initiative XXXX Research Head, Marly Henniga.

Update 11/1/19: SCP-XXXX was gifted a guinea pig as a potential item of interest, rewarding him for continued cooperation. SCP-XXXX immediately marked said guinea pig with SCP-XXXX-1, and has yet to remove it. SCP-XXXX has showed no signs of wanting to study the guinea pig, instead has appeared to become fond of the creature. SCP-XXXX is to be allowed to keep the guinea pig as it is the first instance of SCP-XXXX-1 being used out of liking rather than curiosity. As a result, SCP-XXXX is to be supplied with a 1.6 kilogram bag of pet food pellets on a weekly basis. SCP-XXXX's interactions with the guinea pig are to be tracked 24 hours a day, so that they may be further studied and understood.

Description: SCP-XXXX is an adult male of unknown ethnicity. SCP-XXXX stands at a height of 1.76 meters. He is seen always wearing a black [BRAND REDACTED] hoodie, and grey sweatpants that cover the majority of SCP-XXXX's body. SCP-XXXX wears a semi-spheroid, mirrored mask with no eye, nose, or mouth holes. The mask has no straps or any other fastening devices to keep it attached to SCP-XXXX's face. The current working theory is that the mask is made of a one way mirror, as SCP-XXXX does have the ability to use visual senses. As of the current date, SCP-XXXX has no need to consume any form of sustenance to continue functioning healthily. SCP-XXXX lacks the ability to speak or make any form of vocal noise. Whether this is due to inability or choice is yet to be determined.

SCP-XXXX has a constant drive to study and observe his surroundings. When SCP-XXXX finds a location, item, organism, etc. he deems interesting, SCP-XXXX will mark said location, item, organism, etc. with a symbol made of an unknown substance, henceforth designated as SCP-XXXX-1. SCP-XXXX-1 is not applied to a surface in any way by SCP-XXXX, rather just appears instantly on the surface of the location, item, organism, etc. the moment SCP-XXXX deems it a location, item, organism, etc. of interest. Likewise as soon as the location, item, organism, etc. is no longer of any interest to SCP-XXXX, SCP-XXXX-1 immediate disappears off of the surface is was on.

To date, no attempts to remove SCP-XXXX-1 from a surface have proven successful. The only known way to remove SCP-XXXX-1 is to allow SCP-XXXX to study the location, item, organism, etc. until he is satisfied and decides to remove SCP-XXXX-1 himself. Other than being irremovable, SCP-XXXX has also proven impenetrable, no matter the surface SCP-XXXX-1 is applied to. Once in place nothing is able to pierce SCP-XXXX-1. Multiple tests have been conducted trying to penetrate SCP-XXXX-1 while on multiple surfaces varying in strength and density, non of which have been successful (see testing logs below).

SCP-XXXX remains in a default docile state except under the following conditions:

1. an attempt is made to remove the mask from SCP-XXXX

2. SCP-XXXX-1 is attempted to be covered up by paint or any other coating-like substance.

When one or both of these conditions are broken, SCP-XXXX will go into a severe state of aggression in which he will gain inhuman levels of strength, speed and endurance. SCP-XXXX is somehow able to sense when an instance of SCP-XXXX-1 is being covered, even when many kilometers from the site of the SCP-XXXX-1. The current working theory is that SCP-XXXX-1 acts as a sort of tracking beacon that allows SCP-XXXX to find and return to marked locations, items, organisms, etc. of interest. When an SCP-XXXX-1 has begun to be covered up, an alarm-like system is triggered inside of SCP-XXXX, causing the state of aggression.

SCP-XXXX was discovered in [CITY REDACTED], Massachusetts, after a series of 87 similar vandalism reports were brought to police over the span of three months. All reported "graffiti vandalisms" were instances of SCP-XXXX-1, which was, at the time, thought to be the signature of a new up and coming graffiti artist. MTF ETA-10 was sent in on October 23, 2019 (SCP-XXXX was considered a "visual danger" at the time of discovery) after the reported death of a subway janitor who was "torn to shreds by a mask assailant" after attempting to paint over one of the SCP-XXXX-1s which had appeared on the wall of subway station B in [CITY REDACTED].
