Subject Number: XXXX
Class: Neutralized [Euclid]1
Special Containment Procedure: SCP-XXXX is to be contained at where it perished with any biological lifeforms forbidden from getting in 20km (twenty kilometers) range, any violation is to be neutralized and relocated or terminated. At least 5m (five meters) walls are to be erected just outside the 20km (twenty kilometers) no-man zone above ground to further prevent any and all possible entries. Underground entry are to be permanently contaminated with mercury water by pumping the liquid in sum of 1,000 gallons (one thousand gallons) through multiple 2m by 2m (two by two meters) pipes beneath the walls erected every two weeks. The walls are also outfitted with a recycling drain that reach out underground in the 20km (twenty kilometers) zone that slowly absorbs and filters the mercury in the ground to be reused for contamination. Additionally the sky above are to be blocked by waves of high density pressure no less than 100,000psi (one hundred thousand pounds per square inch) emitted from a cloaked satellite at height of 8km (eight kilometers) above the center of the containment zone. Anti ballistic missiles are to be kept in supply within the base to prevent the satellite from being destroyed by stray satellite or hostile actions.
Should SCP-XXXX manages to revive, all personnel are to evacuate more than 20m (twenty meters) distance away from the containment zone and await for the arrival of MTF Lambda-4 and MTF Eta-5, with permissions to use mercury ballistic weaponry present within the base.
If the two task forces are not enough to recontain SCP-XXXX for any reason, MTF TAU-5 is to be mobilized and captures the SCP-XXXX with O5 permitting possible assistance from SCP subjects deemed suitable for the mission.
Mercury poisoning proven to be most successful method at this present time and therefore MTF TAU-5 should not be deployed under any regular circumstances.
Upon succession, surviving members are to construct a new containment zone surrounding the SCP-XXXX and contain it with 100 (one hundred) arch-like 3m diameter (three meters) Tungsten steel pins sealing each of its heads to the ground. Two colossal titanium gauntlet cuffs 3.189m (3.189 meters) in length and width for each piece wrapping around the forearms of the SCP-XXXX. The hindlegs and the tails are to be pinned each by a long nail in titanium style at 5m (five meter) then heated and fused to the other nails.
It is to be additionally fed 1 gallon (one gallon) mercury waters each day through use of a specially designed water cannon.2
Upon confirmation of its death, proceed with the previous containment procedure.
Description: SCP-XXXX is a 15m (fifteen meters) mountain range going under the name of ███████ ████ in ██████ █████ ██ ███████ in the █████ ██ ███████ but in actuality is a black colossal dragon known as ██████, while records survived, few remains readable detailing how it first felled in the ancient time before homo sapiens thrived. ██████ became known to SCP Foundation after a spy from █████ who was living on the mountain became sick and ███████ sent several undercover agents to check on his condition only to disappear. SCP Foundation investigated this and recognized the mountain range as an object that should not have existed in ███████ and in midst of containing the zone, the SCP-XXXX came to life and attacked the Agents and staffs present. Although this took several days, but the hundred agents and staffs that had mercury pills ready to commit suicide in case of the mission failure were eaten by SCP-XXXX and it fell in agony before eventually dying again, thanks to this SCP Foundation were able to sketch up a containment procedure fairly quickly, then swiftly contained the zone, and erased all evidence of SCP-XXXX existence from satellites present at the scene.
First Incident
On █/██/████, reports of a ███████ intelligent operative arrives at a desk of O5-█.
On █/██/████ O5-█ authorizes mobilize of ███ Foundation agents to the █████ ██ ███████.
The next day appropriately ██ agents reported the mountain range ███████ ████'s existence to the Foundation.
On █/██/████ ███ staffs were deployed to the █████ ██ ███████ to prepare the containment of ███████ ████.
In mere █ hours of deployment, bio signals from ██ agents and staffs were lost, reports incoming from the surviving ███ members informing O5-█ of the existence of SCP-XXXX
MTF Eta-5 deployed after ██ hours of the final communication.
On █/██/████, SCP-XXXX is contained.
Sample Experiment
Several blood were drawn from SCP-XXXX on █/██/████ for testing. At least ███ vials ready to use.
Of ███ vials, 8 (eight) were used.
Out of 8 (eight) vials, two were contaminated with mercury. Lab report shows the blood cell sample being poisoned at profound speed greater than the speed our brain respond to pain reception within our body.
Of the remainder 6 (six), the blood sample were aggressively moving around attempting to consume the glass containers surrounding them.
Upon closer examination, the glass were ever so slightly melting and being corroded by the blood.
Testing of one vial being submerged in a pot of mercury, the blood inside attempted to escape to above the sea level of mercury successfully popping out the clog. Immediate action were taken to contain the blood within the mercury pot. No trace of blood remains after ██ minutes.
2 (two) vials are exposed to the Elephant's Foot in █████████ with assistance of a remote controlled drone, shows absolutely no reaction. Later footage are lost to the radiation, preparation were taken to ensure the vials are dropped into a pot of mercury beneath the vials via grip tension failure.
Additional tests pending approval.
Preliminary Report
Curiosity of how ██████ became known as ███████ ████ prompted Dr. Shawn ██████ to research SCP-XXXX.
Through use of satellite images from over ██ years of mapping, Dr. Shawn was able to pinpoint the exact date ███████ ████ appeared in ███████ ████████ ████ from ███████. The image date is [DATA EXPUNGED].
Dr. Shawn claims and proved the time of when the discovery of SCP-XXXX shows that until [DATA EXPUNGED] and as such should classify SCP-XXXX as [DATA EXPUNGED]
While the testing is unconfirmed, Dr. Shawn believes SCP-XXXX can be contained underwater. O5 members rejects the idea due to the fact one simply cannot move a mountain, nor that lifeforms underwater could be prevented from approaching SCP-XXXX.
Dr. Shawn's findings on how SCP-XXXX could camouflage itself as a mountain shows that its black scales cell structure are very similar to that of a chameleon, but attempts to confirm it have all failed due to the fact the scales cannot be pulled off, only pierced through. More details to be concluded regarding the body of SCP-XXXX at a later date.
