Item #: SCP-[][][]]

Object Class: Euclid

Special Containment Procedures:
SCP-[][][]] is to be contained within a circular containment unit made of 10cm thick ballistic glass about 10 meters in diameter. with an access airlock made with high-grade steel doors. Four guards are to patrol around the container at any given time. In the event of SCP-[][][]] becoming violent, the containment unit can release a powerful neurotoxin which will knock SCP-[][][]] out. SCP-[][][]] is provided with bedding, workout equipment, and 3 standard meals a day. In the event of a lockdown, steel panels will be lowered around the containment, to prevent both SCP-[][][]] from breaking out and anything else from breaking in.

Description:
SCP-[][][]] appears to be a male human in his mid to late twenties of European descent. His eyes and hair are faded gray in color. SCP-[][][]] is capable of understanding most speech, but will not or cannot speak. The reason for his muteness is unknown. It stands 1.78 meters tall and weighs about 75 kilograms. Oddly, SCP-[][][]] possesses no genitalia of any kind and gets rid of any waste through his feces. Aside from these traits, SCP-[][][]] appears to be physically human.

SCP-[][][]] possesses inhuman strength and speed. It is capable of lifting over 1000 kilograms and can keep up with some ground vehicles. It seems to possess enhanced senses, like smell and hearing. SCP-[][][]] can regenerate from mild injuries. It has been shown to heal from cuts in a matter of seconds and mend bones in a matter of hours. By far, SCP-[][][]]’s most intriguing ability is his ability to manifest bone-like armor around his entire body. While the armor looks like bone, it is hundreds of times tougher, capable of resisting explosions and high caliber weapon fire. Combine this with his regeneration and it is extremely difficult to kill. When SCP-[][][]] activates its ‘mask,' it seems to make a low, growl-like hum. This is the only vocalization SCP-[][][]] has ever made.

Despite these abilities, SCP-[][][]] is not hostile towards unarmed or helpless individuals. It will, however, react hostilely to anything it perceives as threatening or a threat to the helpless, seeming to indicate that SCP-[][][]] is a protector. Early in his containment, SCP-[][][]] broke out of containment to grab and shield a researcher because it thought that the guards escorting him were threatening the researcher. SCP-[][][]] has since learned that the guards in the Site are not a threat to others and will not attack unless they are acting hostilely. When in this ‘protective rage,’ SCP-[][][]] seems to prioritize women, children, the weakened, and the elderly for protection, but will more likely attack and hold the attention of the perceived threat.

Additional:
SCP-[][][]] was discovered while a containment team was responding to a sighting of previously unknown instances of SCP-939. By the time the team had arrived on the scene, SCP-[][][]] had already killed 5 instances of 939 and was in the process of killing the 6th and final one. When SCP-[][][]] saw the team, it did not initially act hostilely but was clearly ready to. The team’s leader, Sergeant [][][][][] [][][][][][][], holstered his weapon in an attempt to interact peacefully with SCP-[][][]]. However, SCP-[][][]] saw the weapons being carried by the rest of the containment team as a threat to Sergeant [][][][][][][], and proceeded to take down each member in a nonlethal manner before retreating to protect Sergeant [][][][][][][]. The secondary team moved in and managed to land multiple high powered tranquilizers designed for SCP-939 into SCP-[][][]], rendering him immobile.

Upon further inspection of the area, the teams also found a woman and her child. According to her account, they had followed the voices of SCP-939, believing it to be her husband, only to be cornered by them. SCP-[][][]] appeared out of nowhere and immediately killed two of the instances. The woman stated that before SCP-[][][]] went to kill more of SCP-939, it turned and looked at them, seemingly to see if they were alright. The woman and her child were taken to a foundation facility, debriefed, given amnestics, and returned to their home.

SCP-[][][]] was then transferred to Site-[][] and restrained with military-grade steel chains. After the incident with the researcher mentioned earlier, it was transferred to his current holding cell. After the guards reported seeing him doing various exercises to pass the time, Dr. J[][][][] S[][][][][], the researcher in charge of SCP-[][][]]’s containment and observation, requested a few pieces of exercise equipment for him, including a treadmill, some weights, and a punching bag.

Despite his animalistic tendencies, SCP-[][][]] seems to actually be a skilled fighter, showing proficiency in multiple martial arts including Boxing, Judo, Kendo, Krav Maga, and Brazilian Jiu-Jitsu. It seems to prefer techniques that grapple and incapacitate. During a test, SCP-[][][]] took down four highly trained agents in only a few seconds. When asked where it learned such skills, SCP-[][][]] did not give an answer. Whether or not this was simply because it seems physically incapable of speaking is unknown.

Addendum [][][]]-A:
Further testing of SCP-[][][]] has been permitted to test the full extent of his durability. Thermite grenades, M829a4 tank shells, and anti-tank ammunition have been permitted. SCP-[][][]] has given his consent to be tested.

• Thermite Grenades: The extreme temperatures generated by the thermite did no visible damage to SCP-[][][]]’s armor and SCP-[][][]]’s regeneration countered any damage done to his tissue.
• M829a4 Tank Shells: While fully armored, the most that the explosive shells did nothing more than push SCP-[][][]] back. It took nine direct hits before any damage was visible on SCP-[][][]] ‘s armor. Testing was paused until the next day to allow SCP-[][][]]’s armor to fully regenerate.
• Anti-tank Ammunition: Proved slightly more effective than the tank shells. Six shots to the same area managed to pierce through SCP-[][][]]’s left pectoral armor. SCP-[][][]] managed to pull the bullet out of his body and fully regenerated.

Additional Notes: SCP-[][][]]’s feats of durability continue to impress the staff at Site-[][]. Further testing has been proposed to test any resistances that SCP-[][][]] may possess, such as electricity and cold. Many have proposed fully utilizing SCP-[][][]] as a Thaumiel class entity, similar to the utilization of SCP-076-2. This request is to be brought forward to the 05 Council.

Addendum [][][]]-B:
The testing of SCP-[][][]]’s durability and resistances has continued. Testing for SCP-[][][]]’s resistance to electricity, cold, acid, and poisoning.

• Electricity: Over 400 amps were sent through SCP-[][][]], more than 2000 times the lethal level, with no negative effects. Amps increased continually until the generator being used was shorted out. Aside from a few muscle spasms, no side effects.
• Cold: Temperature in the test chamber was dropped to -300 degrees centigrade. While SCP- [][][]] was too frozen to move and his regenerative abilities were slowed, it did recover fully when thawed. No other negative effects. The possibility of using cold as an emergency containment method for SCP-[][][]] is being discussed.
• Acid: SCP-[][][]] was exposed to numerous powerful acids. His armor remained completely unaffected and while it seemed able to eat through his skin faster than it could regenerate, like his armor, his bones were completely immune, suggesting that the substance his armor is made of is, in fact, the same as his bones.
• Poisoning: SCP-[][][]] was injected with a small amount of Tetrodotoxin, the deadliest neurotoxin in the natural world. SCP-[][][]] went through all of the symptoms at a normal pace before seeming to be terminated. However, after a few minutes, SCP-[][][]] regained consciousness and stood up. It vomited up what little it had left in his stomach and was checked by medical staff. The neurotoxin left behind no negative effects save for headache and occasional muscle spasms which lasted 2 days after the conclusion of testing.

Additional notes: It is easy to see how powerful SCP-[][][]]’s regenerative abilities are. The demonstration that it can recover from even things as deadly as sub-zero temperatures and neurotoxins shows his usefulness as a securing and containment tool. Additionally, it was decided to use neurotoxins for the emergency containment of SCP-[][][]].
