SCP - 5201
SCP Codename: Survivor.
Object Class: Unknown.
Special Containment Procedures: None at this time. SCP 5201 seems to be preoccupied with the pursuit of sight-seeing and refuses to stay in one place long. We are uncertain at this time if he is on any specific route or if he is simply on a walkabout. Regardless, due to the events at the Cortez Motel in Santa Cruz, NV. on 08/13/1993 (hereafter referred to as "'The new door' event"), it is highly unlikely containment of SCP 5201 would be both feasible and useful for the foundation.
Description: SCP 5201 is a caucasian male human standing approximately 2 meters or 6 foot, 7 inches in height and weighing between 175 and 200 lbs. His apparent age is that of 45 but personal tasked with finding any record of the subject have failed to corroborate his exact date of birth. The subject has auburn hair, cropped short, lite blue eyes, and a goatee. SCP 5201's clothing seems to consist of heavy-duty work apparel of the sort one would purchase from Duluth Trading co.
SCP 5201 exhibits anomalous properties of invulnerability to any physical attacks on a variety of levels. This isn't to say he doesn't sustain damage to accidents, but that he sustains none from actual assaults. He also seems immune to the effects of biological, nuclear, chemical, other anomalous and memetic hazards. Furthermore, Due to his actions in "The new door" event, it seems that SCP 5201 has at some time acquired substantial combat training of frightening nature from an unknown organization. Due to his shy nature, it is highly unlikely that anyone will encounter these facts. SCP 5201 has displayed a keen understanding and unmatched aptitude for use of all forms of weaponry and combat and is capable of unwavering creativity and ruthlessness when given no option to withdraw from conflict. To date, no one has successfully deescalated SCP 5201 back to stage 2 from stage 3 but will extricate himself to a location he deems safe and regress to the alpha state, usually by means of sleep or by consuming a substantial amount of alcohol.
SCP 5201 has four stages of being. First, there is the Alpha state which he maintains on a day to day basis. In this stage, SCP 5201 operates as normal person who hasn't a care in the world. While in this state, he is a shy but kind person who just wants to keep to himself and experience the world in peace. Foundation researchers have noted in this state, that SCP 5201 has cut himself shaving, bruised his thumb with a claw-backed hammer, and sustained a rash from a poison-ivy bush when he tripped on a log.
In the second stage which is referred to as the "Heightened State", SCP 5201 becomes agitated, bold, and slightly forceful. While in this stage, SCP 5201 will attempt to dissuade an aggressor from persisting to assaulting him or others in his vicinity. This state seems to be a defensive state and is the best time to activate Mobile Task Force Z-Gamma 47 (Shadow Wanderers) to extract the immediate target of the carnage that would ensue. Should Z-Gamma fail to intervene to stop SCP 5201 from entering stage three, they should focus on evacuating as many people as can be safely moved.
NOTE: The amount of damage to ensue is proportional to the threat.
Stage three is referred to as "Going to War". In this state, alongside his invulnerability to damage, SCP 5201 also demonstrates heightened strength, agility, stamina, speed, tactical aptitude, and awareness. He also loses any amount of empathy he showed for his opponents and his environment (save for any person he is defending). While in the "Going to War" stage, SCP 5201 has the capability to and willingness for totaling eradication of any opponent. See "The New Door" Event.
Stage four is at this time only hypothesized but is pre-emptivly referred to as the "Oh Hell No" state.
New Door Event
Location: Santa Cruze, NV. - The Cortez Motel- roughly 9:45 PM.
Foundation agents were stopping into the motel for the night on the way to a low-level sighting and decided they needed some liquid refreshments. While in the motel bar they witnessed a leather-clad townie harassing and on the verge of molesting a female patron. Being as the foundation has strict time frames for investigations, they chose to not get involved to avoid any potential trouble that getting involved may cause.
From the end of the bar, however, came a harsh yell which first drew attention to SCP 5201. He stood up and strode over, wedging himself between them. The agents couldn't hear what was said between the man and SCP 5201 but it ended when the man pulled a pistol from his side and shot around at SCP 5201. When SCP 5201 didn't so much as flinch as the bullet dropped to the floor, the agents bore witness the first recorded instance of Stage three. The man with the gun began to fire round after round to only have them all land on the floor, flattened. SCP 5201 grabbed the man and through him at one of the buildings inner walls. The man crashed through it and into the next building, creating a new door. Upon corinors investigation, it seems he had already died of a crushed neck before he hit the wall. SCP 5201 then ran out the back door, leading foundation on a three-week manhunt before going off the radar for another subsequent two months.
During this time, foundation operatives struggle to ascertain the scope of the subject by scouring its vast databases for an uncontained humanoid with heightened strength. Below is a Foundation communication transcript from 09/03/1993 in which the extent of the agent's knowledge is revealed.
Speaking parties are Agent Dosn'tMatter Redacted 1 (referred to as Agent A), Agent Stilltobe Redacted 2 (referred to as Agent B), Foundation Researcher, Doctor Khan-Romariz (referred to as Doctor), and briefly Foundation Switchboard Operator.
Foundation Switchboard: Your communication is being put through now. Remember, your's is not a secure line and as such, OpSec protocols must be maintained. Please wait.
Agent A: Yeah, yeah. Thanks. Can't wait for them to upgrade the system. Seems like this switchboard people always listening.
Doctor: Do you have any idea how much trouble you and your partner are in for going off the reservation like this?! You missed your rendezvous with our eyes in Vegas, blew off the collection altogether, and have decided to do what? Play grab-ass in the desert?! You better have a damned good reason for why your not D-Class as of three days ago!
Agent A: Doc, listen. Bambi is out of the VCR. I repeat, Bambi is out of the VCR. There's a new star shining. Bambi got two thumbs, new star is 6 thumbs. Rated NC 17, permission to fast forward?
Doctor: Really?! Movie references? Where are they getting you guys! So you want me to OK your ditching the collection mission in Vegas on account that you found bigger, more dangerous prey? I need more to go on here.
Agent B: (From background) tell the dick, they wouldn't like him angry.
Agent A: (pauses for a second) You wouldn't like him when hes angry… Anyway, Jeckle turned Hyde out here at the STD farm. Gave a new A/C to the watering hole and put a cold one in the fridge before pulling a ditch job. Pumps maga iron or wear it. Left washers on the floor We've been trying to deliver his mail since without success.
Doctor: Strong enough to kill and punch holes in walls do not an SCP make. He could have been wearing body armor for all you know. What makes this guy so much more important?
Agent A: This is getting difficult to phrase here doc, so to hell with the OpSec shit. The guy got shot in the unarmored by an S&W 500 of the target and he didn't spill his drink let alone any blood. then the target grabs the guy buy his throat, crushing it I might add before he fully lobs the guy through two sets of 1-foot thick rebar reinforced masonry into the building next door. This guy is some kind of a monster and he's loose. we need reinforcements pronto, but we will settle right now for foundation blessing.
Agent B: This guy's like the god damned Hulk and all your asking for is their blessing? The hell is wrong with you?! We're not rated for the level this guy is, have them sent a task force after him and let us get back to the mission. Unless you're trying to get D-Class'ed!
Doctor: Agent B is correct. You two have wasted enough time. proceed to the original target. I will have a task force contact you for the details shortly. And boys?
Agent A: yeah?
Doctor: Read a fucking book some time. (Doctor terminates communication)
Foundation Switchboard Operator: Your current Portal of communication will receive an electrical burst in one minute. Please place the handset back on the cradle and stand back.
After this communication, Task Force Z-Gamma 47 (Shadow Wanderers) were activated to track SCP 5201 down and capture it if possible. Destroy it if necessary. On 10/12/1993, the forward team from Task Force Z-Gamma 47 encountered SCP 5201 in a storage facility in Reno, NV. They opted to engage the target before Task Force command could give orders. The forward team consisted of six highly trained soldiers bearing advanced military-grade weaponry and practiced in close quarters tactics. Upon contact with SCP 5201, Forward team chose to attempt to overpower him by numbers and intimidation. This appeared to succeed in stunning him for a moment until one of the team jammed the but of his rifle in the side of SCP 5201. Once contact was made, SCP 5201 ripped the gun from the offending soldier and rammed the barrel through his neck before he beginning firing at the other team members, using the first as a shield. He then pulled a pin on a grenade suspended from the belt of the dead soldier before kicking him into one of his squadmates.
The resulting explosion destroyed the building and killed the three of the remaining four forward team members. The only soldier who managed to get cover reported that the target was standing almost on top of the explosion but when he managed to look after the explosion he stood undamaged, wearing rags that were his clothing.
