Item #: SCP-XXXX
Object Class: Euclid Neutralized/Safe1
Special Containment Procedures: Site-XXXX has been constructed around SCP-XXXX.
Description: SCP-XXXX is the collective designation given to an apartment in ████, Idaho and its sole inhabitant, SCP-XXXX-1. Matter within SCP-XXXX is designated SCP-XXXX-A. SCP-XXXX-1 is a humanoid Type-Green "Reality Bender" entity, genetically identical to Gregory █████. Gregory █████ has not exhibited any anomalous activity and has not shown abnormal Hume levels, but is monitored daily by Foundation agents.
The primary anomaly of all SCP-XXXX components is an inability to be affected by Hume-based reality alterations. Other than this property, SCP-XXXX-A is indistinguishable from non-anomalous matter. Scranton Reality Anchors fail to stabilize Hume levels of SCP-XXXX-A, and Kant counters cease to display Hume level readings of the anomaly. Through testing with SCP-████, it was confirmed that other reality benders cannot affect SCP-XXXX-A. Conversely, SCP-XXXX-1 cannot influence any matter that is not composed of SCP-XXXX-A. Although SCP-XXXX-A can spread if not properly contained, thus expanding SCP-XXXX-1's field of influence, baseline matter cannot be converted into SCP-XXXX-A, nor can SCP-XXXX-A be converted into non-anomalous matter.
Addendum A: Discovery Log:
SCP-XXXX was originally discovered in ██/██/████, after reports of a building spontaneously appearing in the middle of an uninhabited area. After a failure to remotely observe the inside of the building, (later learned to be SCP-XXXX-1 unsuccessfully attempting to hide the building) Agents Jennifer S████ and David D█████ were deployed to investigate the inside.
D█████: Maybe we should ring the doorbell?
There is a pause.
D█████: Sorry, bad joke.
S████: Let's just get this over and done with, okay? Once we isolate the anomaly, we can go.
Agent S████ opens the door, and the two quietly step inside SCP-XXXX. When viewed from inside, the building's interior is visible. An angry voice is heard from a higher floor.
D█████(very quietly): Okay, let's go up on my signal. Three, two, one, go.
Agent D█████ leads the way up the stairs, as the voice becomes more clear.
Unidentified Voice: -aren't they working? No, no, no, this can't be permanent, I'll get my powers working again, and I'll take back my world!
The agents reach the second floor. SCP-XXXX-1 can be seen holding its head in its hands, spatial distortions rippling around the entity.
Agent S████ fires a tranquilizer dart into SCP-XXXX-1's neck.
Note: Due to an error in management, Agents S████ and D█████ were not equipped with the correct ammunition.
The entity grunts in pain, then stands, turning to face Agent S████ with a smirk.
SCP-XXXX-1: Really? You're even stupider than the others. This is my world. That dart is mine. Its poison is mine.. And… (SCP-XXXX-1 shrugs.) I don't want it here anymore.
SCP-XXXX-1 makes a gesture with its hand.
There is no discernible change in reality.
SCP-XXXX-1: I- the- dart- my- (stutters) you-
SCP-XXXX-1 collapses into unconsciousness.
Subsequently, Site-XXXX was built around the anomaly, and once SCP-XXXX's anomalous properties were confirmed, the current containment procedures were implemented.
In interviews, SCP-XXXX-1 has exhibited megalomania and sociopathic tendencies. SCP-XXXX-1 has a particular obsession with holding power over others, and is continually frustrated by its own inability to influence matter outside of its field of influence. These traits appear to be absent in the non-anomalous Gregory █████. This behavior has impeded efforts to study the anomaly.
Addendum B: Interview XXXX-1-01:
After initial containment was achieved, interviews were conducted through speakers placed in the walls, to prevent breach of SCP-XXXX-A.
Researcher Y███: Excuse me
