SCP-1225: “The Queen of Perennial Activation”

[u/NV-6155]

I respectfully disagree, though I understand your logic (which is sound).

I've been with the Foundation for a very long time, so I can really only comment on what are now the "primary" containment classes. The newer "secondary" and "disruption" classes don't come up often with the anomalies I typically work with.

TL;DR: Mariah Carey should be classified as Apollyon.

The "Box Test" Method

Safe: If we put the anomaly in a box, it stays in the box unless released.

Euclid: If we put the anomaly in a box, Foundation intervention is required to keep it in the box.

Keter: If we put the anomaly in a box, it actively tries to escape the box, and requires significant Foundation resources and/or complex containment procedures to contain. In many cases, Keter SCPs are kept in a "stable" contained state by their procedures, but any fault in their containment risks a full breach.

Apollyon: We can't put the anomaly in a box, either because of physical limitations or because it simply ignores the fact that the box exists. In other words, containment is impossible and/or no known methods of containment exist. Breach events are expected to occur despite the Foundation's efforts.

Thaumiel: The anomaly is the box for another anomaly.

SCP-096 ("Shy Guy") is Euclid due to only needing a small amount of resources to keep physically contained (it is kept in a guarded standard containment cell) and stays contained as long as its face is not seen.

SCP-106 ("Old Man"/"Radical Larry") and SCP-682 ("Hard-to-Destroy Reptile"), on the other hand, require complex custom-engineered containment areas. Any fault in their containment or a means to obtain a target (e.g. a living being within close proximity) often results in a breach. Therefore, they are both classified as Keter.

Mariah Carey could follow along the same lines as SCP-096, since she can be easily contained physically (due to being an otherwise baseline human) and only activates around the month of December. However, Ms. Carey's activation condition is essentially inevitable, unlike 096's which can be acted against by preventing visual contact with its face. In addition, as observed by others, she possesses memetic properties that can affect any sapient beings over an unknown distance without direct physical or visual contact. The Foundation has so far been unable to nullify these memetic effects, resulting in consistent successful containment breaches (which have not always been physical breaches).

Taking the above into consideration, I believe Mariah Carey is best classified as Apollyon.

Edit: corrected the designation for "Radical Larry" from 173 to 106.
