Object Class: Euclid
Special Containment Procedures: SCP-XXXX is to be kept in a 6 meter by 6 meter by 2.5 meter steel containment cell kept within site-32. The containment cell is no longer to be installed with a ventilation system, see addendum SCP- XXXX-1. In case of containment breach site-32 is to go on lock down, all non-security personnel are to stay in the same room as they were at the time of breach and remain stationary, any person found to move towards an officer is to be immediately neutralized.
Description: SCP-XXXX is a hairless quadruped measuring about 112 centimeters at the shoulder, SCP-XXXX is capable of bipedal movement for short periods, while bipedal the creature reaches a height of about 1.7 meters tall. SCP-XXXX has enlarged teeth that are not covered by any form of lip, it has two eyes on either side of it's head that are capable of sight even through extremely dark environments. SCP-XXXX has three claws at the end of each of it's legs, the claws are extremely sharp, and are comparable to a surgical blade. SCP-XXXX is capable at running at 50 kilometers per hour, and is strong enough to easily tear through tough materials such as Kevlar.
SCP-XXXX will kill it's prey by disemboweling it via a quick incision along the spine, SCP-XXXX is capable of killing it's victim in a matter of seconds and seems to have no trouble suppressing the noise that it's makes during the attack. The creature will than remove all of the contents of the body leaving only the skin, it will quickly consume the organs and bones and proceed to push itself into the skin and stand up straight, mimicking the dead human. SCP-XXXX makes no attempt to cover up the incision in the back of the skin, and will simply walk through areas until it spots another human, it will than tear through the skin and kill the victim, after which it uses the new victims skin to repeat the process until it is discovered. In cases of their being two or more people at a given time, SCP-XXXX will eat the excess humans in their entirety and than use the last human to start the mimicking process.
SCP-XXXX does not seem to have a need for oxygen or food, during a containment breach researcher [REDACTED] attempted to lock the creature in the on site freezer, after forty days of the creature being isolated a security team was sent to re contain it, the security team opened the door and was immediately attacked by SCP-XXXX, leading to 22 deaths before containment was achieved. SCP-XXXX is not capable of permanent death, the death of the creature will cause it to remain unconscious for a period of about 50 hours, after which it will start to regenerate from it's injuries and return to its normal behavior in under 5 minutes.
Addendum SCP-XXXX-1: No sound was heard from SCP-XXXX's cell for 9 minutes before two janitorial staff were declared missing, a containment breach was declared and a sweep of the site was commenced, within an hour the creature was found in the body of doctor [REDACTED], and temporary termination of the creature was achieved. Inspection of SCP-XXXX's cell indicated the use of the ventilation system to sneak into the broom closet of site-32 and devour both on site janitorial staff, 8 staff died before re containment and a sealing of the air ducts was commenced immediately.
