File 4: The Thing

SCP#: AAD

Code Name: The Perfect Imitation

Object Class: Keter

Special Containment Procedures: remaining cells of SCP-AAD are frozen and contained in storage freezer unit at Site-XX. because of foundations advancing technology, it is with hope that testing on SCP-AAD will eventually be possible. However, until the proper gear is constructed, and every safety measure is considered SCP-AAD will remain in its containment unit. no testing is allowed as of the moment. Any personal that come into contact with SCP-AAD freezer unit must be checked with the updated anomalous biological scanner and incinerated at the slightest results of SCP-AAD infection. there are no exceptions.

Description: SCP-AAD is a hostile and violent biological shifting organism of great intelligence and power. SCP-AAD cells seem to be supercells and each one acts as a whole with the only limitation being size. SCP-AAD has the ability to mimic any biological organism it consumes or comes into contact with. SCP-AAD prefers to violently infect its prey however SCP-AAD is able to spread cells to the intended prey through physical contact without the victim noticing they've been infected. The chances of infection via this method is 75%.

SCP-AAD is extremely infectious and can only be destroyed by incendiary, explosive, or electrical methods. SCP-AAD is not immune to other forms of damage however in order to suppress/ kill SCP-AAD is to destroy the cells directly; any other damage just angers SCP-AAD or causes it to slit into smaller instances of itself.

SCP-AAD psychology is entirely unknown. Even with the reports form [data expunged] and [data expunged] it is confusing to understand SCP-AAD. When SCP-AAD consumes and imitates a human being it is able to recall all of their memories and even enact their personalities with perfect accuracy. Though even then the personality, psychology, and ideology of SCP-AAD itself is entirely unknown. All that is known is that SCP-AAD desires to infect and consume all forms of life by any means necessary.

SCP-AAD mostly prefers to infect by stealth and careful contact with its prey. Only until all or most prey have been consumed and/ or imitated will SCP-AAD start its true plan. SCP-AAD will use its vast intelligence to construct a ship that to have easy interstellar and planetary location access. SCP-AAD will also start creating lesser versions of itself to spread around and find any additional prey in the area and surrounding areas.

SCP-AAD is extremely intelligent and is able to retain memories even from the smallest functioning cell. As such testing might never be permitted as to prevent SCP-AAD from adapting to containment and learning secrets and weaknesses of the Foundation.

SCP-AAD was discovered at a US research station at Antartica in 1982, after a tip off report form [data expunged] who survived the first encounter of SCP-AAD. [data expunged] and [data expunged] were the only survivors of both encounters with SCP-AAD. Both of which ended up being recruited into the Foundation with [data expunged] working as a Feild Researcher and [data expunged] as the newest Epsilon-9 MTF unit.

"SCP-AAD might just be the most dangerous SCP we have ever encountered. Sure, we got the thing contained but that doesn't deny the fact that if it ever got out it has the power to wipe out the entire world. even SCP-682 doesn't have the same destructive potential this thing has. It lives and infects by the cellular level! even a flamethrower won't kill it! not permanently at least! We need to ensure that SCP-AAD never breaks out of containment. If SCP-682, SCP-610, SCP-096 and over dangerous organic based SCPs got into contact with SCP-AAD it would lead to an unstoppable killing machine. Worst off if the Sarkic cult or worse the [data expunged] were to find SCP-AAD... then that would mean the end of the world... let me repeat myself, SCP-AAD must NEVER be allowed to breach containment... and if the O5 is willing to hear me out... destroy it." - Director Brian.

The O5 council has rejected Director Brian's request to destroy the remaining animated cells of SCP-AAD.
