SCP-████
Object Class: Euclid
Special containment procedures: SCP-████ does not show signs of resisting containment and even seems to prefer to be isolated in a small cell. SCP-████ is to be held in a 3m by 3m by 3.5m containment cell made of reinforced concrete. Only level 3 or higher personnel are permitted to enter SCP-████’s containment cell.
Description: SCP-████ is a bipedal humanoid being that has abnormal physical qualities. SCP-████ is braced by rods coiled with wires that are held with pipe clamps keeping the wires in place these rods run on top of where some human bones would be including the humerus, radius, femur, and fibula and are held in place by steel cuffs approximately 7 cm away from all joints . All of these rods meet up to a large mechanical system that covers SCP-████’s spine and it is speculated the wires connect to SCP-████’s spinal cord. There are also pivot points that hook up to its joints with hydraulic systems that allow SCP-████ to move at rapid speeds SCP-████ tends to walk on its two legs but when it starts to gain speed it will run on all fours.
SCP-████’s face is also disfigured. It has only one eye (right) that opens horizontally to reveal complete darkness filling the whole eye other than the pupil witch is a beam of bright white light. Below its eye is a set of two artificial fleshy jaws. These jaws fold open at rapid speed to reveal a set of randomly placed razor sharp "teeth" that are made of a different types of iron nails (mostly being cut nails) including a few unique ring-shank nail with barbs.
The space where SCP-████’s jaws fold out from has a small mouth that has only a top row of sharp teeth that seem similar to wolf fangs. SCP-████ does not use these teeth when it attacks their only purpose being to help it tear and eat its food. The remainder of the space is taken up by human gum tissue filled with puncture wounds presumably from whenever SCP-████’s jaws are closed and it’s "teeth" stab onto its face. This process causes extreme pain for SCP-████. When SCP-████ closes its mouth it reveals a series of cage-nuts on the back of its jaws that hold its artificial teeth in place.
SCP-████ is not typically hostile unless it feels threatened or hungary. If/when SCP-████ grows hostile it will enter an enraged state and will attack anything it sees. SCP-████ attack pattern is mostly random and unpredictable but normally rapps it’s unusual jaws around it's victim's head or shoulders. During this state it is best to attempt to hide from SCP-████ and remain hidden until it has been pacified with tranquilizer or sleeping gas.
When SCP-████ attacks its “teeth” release from it’s mouth and stay in its victim the nails then bury themselves further and further in the victim’s flesh but the only damage done to the victim is to its flesh and muscle tissue, organs seem unaffected. Regardless the nails cause severe pain and intense blood loss. When SCP-████ dose this it regrows its “teeth” almost instantly repetitive attempts to research this process have turned up unfruitful. SCP-████ will also lose teeth over long periods of time and when this happens it takes nearly a minute for the lost “tooth” reappear. There is no information on how this process works. So far the only teeth to fall out are five cut nails and one ring-shank nail with barbs.
SCP-████ at one point was a polish male child but was captured by German forces during the Holocaust and was an experimental patient in attempts to ████████████ but the results were not what the Germans had expected SCP-████ later revealed that the German forces attempted to lethelise him but SCP-████ attacked the German forces. SCP-████ was then imprisoned and had his jaws one eye stitched closed. After the Holocaust had ended SCP-████ remained in the abandoned mines where many prisoners had been forced to work in. Years later SCP-████ latched onto the bottom of a train that was on its way to ██████████ where it was first discovered.
