Object Class: Safe
Special containment procedures:SCP-████ is to be kept in a standard humanoid containment cell. Only level 3 or higher personnel are permitted to enter SCP-████’s containment cell.
Description: SCP-████ is a bipedal humanoid being with long thin arms and sharp metal claws. It does not resist containment and behaves like a wild animal attacking only when it feels threatened or when it is hungry. SCP-████ is roughly 7’8’’ tall. SCP-████’s mouth is folded on the lower half of its face and can open to reveal hundreds of "teeth" that are made of a variety of sharp iron nails including a few unique ring-shank nails with barbs. The space where SCP-████’s jaws fold out from has a small mouth that has only a top row of sharp teeth. SCP-████ does not use these teeth to attack their only purpose being to help it tear and eat its food. 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. One of SCP-████’s eyes seems damaged leaving only bloody webbed flesh hanging in the left eye socket its other eye is misty grey and bloodshot.
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 unpredictable with only one consistency, SCP-████ will wrapp it’s jaws around it's victim's head or shoulders. During this enraged state it is best to attempt to hide from SCP-████ and remain hidden until it has been pacified with a tranquilizer or sleeping gas.
SCP-████ is able to speak english but only has once. SCP-████ stated it was at one point was a polish child but was captured by German forces during the Holocaust and was an experimental patient in attempts find ways to produce immunities to hazardous materials for the benefits of their own soldiers. Tests included exposing patients to ██████ ████ and then to small amounts nuclear radiation, and large amounts of many types of deadly bioweapons used in chemical warfare. The results were not what the Germans had expected. The attempted immunities had only amplified the mutative effects. German forces then modified SCP-████ by inserting nails into its jaws in attempts to weaponize SCP-████. The Germans were not able to control SCP-████ and it began attacking the German forces. SCP-████ escaped German custody and remained hidden in abandoned mines where many prisoners had been forced to work in. Years later SCP-████ allegedly latched onto the bottom of a train that was on its way to ██████████ where it was first discovered.
