Interviewed: AO-1504

Interviewer: Dr. Loyd

Foreword: AO-1504 is being questioned on its background.


We didn’t know his true anomaly. We didn’t know what he could really do. [DATA CORRUPT]

[DATA CORRUPT]. I guess he affects computers too. Our automatic security system began to have “hiccups”. A breach here, a breach there. But nothing that surprised us. But then, our Keter got out. Only about half of the staff here realized it. The other half? All died. We managed to contain it.

We sent a request for more staff, but they never responded. Our supplies were dwindling, so we asked for more. Nothing. They didn’t even acknowledge our existence. We had more breaches, more deaths, yet we never questioned these breaches or these deaths. I don’t know why we didn’t question those deaths.


Earlier today, we had a site-wide containment breach. All the doors opened because of those “hiccups” I mentioned earlier. Most of the remaining staff members are dead. Those who are still alive are few and far between. We can’t contain a breach of this magnitude. And the other Foundation sites will probably ignore it. They’ll cite it as completely normal and ignore it.

I’m going to put this in the Vault, then set off the on-site nuke. I’m already badly hurt, and the blast would save more lives than it will end. If anyone ever finds this, tell my wife that I love her and that I’m sorry for spending so much time in my job. Tell her that I said goodbye and that I am thinking of her as I die.

Addendum-1504-3: The Site ███ nuclear warhead was detonated on ██/██/████ to counteract a Class-7 Containment Breach. A total of █ anomalies were destroyed in the blast, █ anomalies were recovered, and █ anomalies are missing, including AO-1504. ███ Foundation personnel died in Site ███.


Item #: SCP-1504

Object Class: Keter

Special Containment Procedures: SCP-1504 is not currently contained. If any Foundation personnel see the subject, they are to contact the current project head. In the event SCP-1504 is found, it is to be brought to Area 1141 and contained in a 3m X 3m X 3m containment chamber.

To enter the subject’s containment chamber, a total of four Level 3 staff members are needed. Two staff members must remain inside the control room to remotely enact the failsafe should a containment breach occur. The failsafe consists of flooding the containment chamber and surrounding areas with Halothane vapor, which has proven to be the only viable method to incapacitate SCP-1504. Extensive research has shown that SCP-1504 can be incapacitated by blunt force trauma to the head. The subject is to be kept fully confined and incapacitated at all times through the use of restraints and Halothane vapor.

The other staff members must release multiple locks simultaneously. A minimum of four guards are to be protecting them at this time. After all locks are released, one staff member may enter the containment chamber. The guards must be ready for a containment breach at all times the containment chamber is open.

No automatic systems may be used in Area 114. All doors and containers must be locked using simple combination locks or simple padlocks. All personnel working at Area 114 must have a high aptitude for parapsychology or a strong resilience to perception shifts.

Description: SCP-1504 is a Caucasian male, standing at 1.95 meters tall. The subject’s appearance is unremarkable, aside from a small birthmark on its right shoulder. SCP-1504’s anomalous traits include its inability to be harmed or killed.

All actions carried out by SCP-1504 will be perceived by surrounding individuals as being within expectations for the situation. SCP-1504 has been known to attack personnel who will then believe circumstance or their own doing has hurt them. The subject is able to affect electronic and automatic systems.

SCP-1504 was brought to the attention of the Foundation because of its inability to be harmed and was classified as an Anomalous Object after initial testing. The subject was held at Site ███ in the Anomalous Object wing of the facility. On ██/██/████, a site-wide security failure and subsequent containment breach resulted in the on-site nuclear warhead being detonated.

SCP-1504 was declared missing after a search of the site did not reveal a confirmed death. A low priority search was issued, but was soon raised to high priority after the above document was found. MTF-Eta-6 (aka. Awareness Filters) was formed to find SCP-1504.

Addendum-1504-1: After being further analyzed and sent through multiple filters, it was discovered that SCP-1504’s responses were different from what was previously recorded. The document has been updated to include these responses.
