containment specifications
SCP unknown must be kept in a 10 foot by 10 foot room make from 5 inch or greater thickness copper. Any other material will prove ineffective against the unknown man. The unknown man is capable of passing through walls and structures. No personnel are to enter this cell, therefore no doors shall be placed
in the chamber. There should be no computers within 100 yards of the chamber(Reasons explained in description)
description
SCP unknown is a humanoid figure made of an unknown substance. This material seems to be liquid but is held by an unknown force in the form of a middle aged man with a baseball cap on. SCP unknown is intelligent and speaks English. He is content with the form he is in and strongly resisted when capture was attempted. SCP unknown claims to be several hundred years old, but there is no evidence to prove this. Any attemp to communicate is difficult because of the muffled sound sounding like he is talking from underwater, only certain things are heard originally thought to be random but on further inspection are selected by the SCP thought to be a protection of his identity.
A strange property of SCP unknown is any computer within a certain range of SCP unknown will be turned on and used to redact information on SCP unknown with no regard to clearance or firewall seemingly telepathically. One more thing on this subject is anyone within the same range as the cube will be affected. Two things can happen to you, one is you will suddenly lose all memory of SCP unknown and walk away. The second thing that can happen is when talking about SCP unknown you will begin talking about something random but usually involving another SCP. This can cause minor headaches, dizziness, extreme confusion, and in some rare cases loud ringing in ears and hallucinations.
SCP unknown has escaped containment 5 times. If SCP unknown escapes a team of 20 D class personnel will be sent to the location with a small copper cube. This cube will be dropped from a height of 15 or less feet. At this time the team of D class will exit a transportation truck and begin to carry the container into the truck. If SCP unknown is not captured within 24 hours the ground and all life around it will begin to turn into the black liquid that makes up SCP unknown. If touched by the liquid the limb will immediately have to be amputated to save the rest of the body from getting infected. The liquid spreads at 1 yard per minute. If the liquid reaches 1000 yards, the liquid will begin to spread by itself even if SCP unknown is captured. This means world termination is imminent. There is no method we know of to kill SCP unknown. This and it’s danger to the human race causes it to be classified with SCP 682. Neutralize immediately.
