SCP-XXXX
Item #: SCP-XXXX
Object Class: Keter Keter-Thaumiel
Special Containment Procedures:
SCP-XXXX is to be kept in a 6m x 6m spherical room, there is to be a hermetically sealed airlock outside the chamber, and no one is allowed to enter the chamber without wearing gear approved by Dr ████. Outside of testing the chamber is to always be depressurised unless overridden by [REDACTED]. Liquid nitrogen is to be refilled by D-class personnel biweekly
Description:
SCP-XXXX is a thick cloud of gas, it is dense, black and is composed of an unknown compound, any lab readings from the compound have come back in gibberish (See Addendum XXXX-1). When a living organism, anomalous or not, is placed within a 2m radius of it, SCP-XXXX will create an object to counteract the anomaly, on every testing occasion, the object has fatally wounded the organism. This can include many things as simple as a bullet or a complex as a [DATA EXPUNGED]. When exposed to liquid nitrogen SCP-XXXX enters a passive state, making it easier to transport and it has been observed that the effect of liquid nitrogen wears off after 2 hours.
SCP-0000 was discovered in ████ Iceland. MTF Sigma-2 “Cold Bonds” Were dispatched after the anomaly had [DATA EXPUNGED] and this was when the method of containment was discovered. It was then dispatched to Site-00 Where it is held today
Additional
SCP-XXXX is not allowed to be tested with any Keter class SCPs Rescinded O5-1, O5-2, O5-10.
Addendum XXXX-1: Note from Dr ████:
After multiple tests and lab readings there has been no conclusive evidence of the compound that SCP-XXXX is composed of. All equipment has either malfunctioned or read back contradictory information so in retrospect, we are unable to indentify what SCP-XXXX is made of.
Addendum XXXX-2: Any cross testing of SCP-0000 and any other scps must be approved by two O5 members.
SCP-0000’s containment chamber is pressurised, subject is D-8787 and the supervisor is Dr Serton. The airlock is cycled and D-8787 enters the room.
D-8787: Ok, i'm inside the room
Dr Serton: Please approach SCP-0000
D-8787: What the hell? Theres a weird fuckin cloud in the middle
Dr Serton: That is SCP-0000, please approach it
D-8787: Jesus christ, ok ok.
*He approaches the cloud, a loud swirling noise is heard*
D-8787: Is it supposed to do that?
Dr Serton: That is interesting, please go closer to it
D-8787: I really dont think-
At this moment a high speed projectile is observed to fire from SCP-0000 and enter D-8787 in his chest, later autopsy saw that it directly hit him in the heart and killed him instantly. Test was concluded and SCP-0000’s containment cell was depressurised.
