Sovient Assassin

First sighting of SCP-XXXX retrieved from Texas state police.

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Subject is to be kept locked in a 510 centimeter thick steel-reinforced concrete container with the internal space of the container to be at the parameters of 5 m x 5 m x 20 m with small vents at the top of the container ready to pump sedative gas into the container in the case of an attempt of a containment breach. Two of these containers should be built in the case one is damaged or requires maintenance. These containers should be used in a weekly rotor to house SCP-XXXX. When a container is not in use it is mandatory that the container be checked for signs of damage on the walls or furniture within. Vibration sensors will be placed on the external walls of the container in the case that SCP-XXXX attempts to break out of it's container. Observation is to be made through a reinforced window on the ceiling of container to view down within the container in the case where visual confirmation is required or that observation is required by a researcher.

SCP-XXXX is to have 24/7 monitoring by at least two guards with a loaded anti-tank rifle nearby in case of a containment breach. To keep SCP-XXXX calm, personal stationed at SCP-XXXX's monitering post are free to make conversation in an effort to gather passive intelligence about the subject and to keep the subject at peace. SCP-XXX is to have no contact with personal, any attempts of communication by SCP-XXX should be ignored. SCP-XXX is permitted furniture at the approval of Dr ██████ Dr █████████ Dr █████ or by 04 personal or higher.

Description: SCP-XXXX is a sentient, humanoid anomaly measuring approximately 1.9 meters in height with a varying mass from approximately 70 - 185240 kg kept in Site-88Area-██. Visual depiction shows that the subject is completely covered by black, scale-like crystals which cover the entire body of SCP-XXXX whilst giving the visual outline of a first-world military soldier. During interviews, SCP-XXX has been noted to be able to speak German, Spanish and French but prefers to speak English. When speaking English, the subject is heard to have the tone of male, refers to being a male and goes by the name "Tiger". SCP-XXXX also has the accent of a US Citizen. SCP-XXXX has also shown during containment breaches that it is capable of handling foundation weapons very effectively with the estimated reflex time and precision of a veteran MTF Operative which has added to a number of casualties by it's hand during containment breaches.

Any damage SCP-XXXX receives in vain as it is able to self-regenerate lost matter, the speed of this effect varies (See paragraph below). In the case a limb is dismembered, it is classed as SCP-XXXX-1 and will remain inanimate however, if SCP-XXXX-1 is retrieved by SCP-XXXX then it can absorb SCP-XXXX-1 and can help speed up the regenerative speed for a short moment. This time can vary depending on the volume of the absorbed limb. What little sightings have been seen of SCP-XXXX losing a limb have been considered opportunities to observe SCP-XXXX's internal biology which has seen to be a purely crimson tissue substance within the black exterior of XXXX. Within the center of an exposed limb their is a white material which was at first presumed to be bone before it was confirmed to be true by X-ray's. In the case that SCP-XXXX-1 is unable to be retrieved by SCP-XXXX then the limb's internal tissue and bone will decay at a rapid rate (Which is unaffected by alternating factors) leaving the black crystal substance behind, designated as SCP-XXXX-2. Any traces of SCP-XXXX-2 are to be found and bagged before being sent of to Dr █████'s lab for analysis. SCP-XXXX doesn't require any basic human requirements such as food and water, however the subject will feel the full effects of being in an environment however in most cases won't receive any clear physical damage.

Subject's alternating mass remains a mystery to Foundation researchers as the the subjects physical exterior seems to increase in density whilst increasing the speed of the self-regenerating ability. This varying effect is theoretically controlled by either sheer mental will or by emotions felt by the subject (See Test-E) however, we do know that the subject's movement is unaffected by the alternating mass.

If a containment breach does occur, alert the Site Director immediately. Researchers should not attempt to engage or get in the line of sight of SCP-XXXX and should evacuate the areas near it's containment area immediately and either follow security personal or head to an evacuation shelter. Security personal equipped with small arms or light firearms are advised to only engage SCP-XXXX if necessary, security personal are also advised to seek the nearest heavy armament and attempt to work with other security forces to ambush and decimate the subject for it to be able to be sedated. SCP-XXXX is vulnerable to certain gases, if it senses or see's an oncoming gas attack it will attempt to break free from the area it is trapped in. In the case it breaks out then it will be required to be blown apart or "Decimated" to be able to fire tranquility darts containing sedatives into exposed tissue substances.

Notable logs:

Test-B - ██/██/████
Subject: SCP-XXXX
Procedure: Expose SCP-XXXX to different chemical gases to see the effectiveness against the subject and what can be used in future in the case of a containment breach. These would be gases you could find yourself in a AR-600 procedure.
Results: SCP-XXX cannot be terminated by exposure to lethal gases but can be used to hinder or sedate SCP-XXXX
Analysis by Dr ██████: Subject is unable to be wounded or killed by chemical weapons that would kill your average person, instead, SCP-XXXX will presumably feel the effects of these chemical weapons. Surprisingly, when exposed to sulfur mustard the subject will recover almost immediately however when exposed to fluothane the subject remained sedated. I think it's safe to assume that SCP-XXXX's sub-conscious can control it's regenerative abilities and that when put to sleep will stop itself from cancelling out the effects of the sedative gas and allows the subject to react as a human would to the same gas.
Audio transcript: 40:56-47:01

Dr: Alright, one more to go and we'll call it a day lads, yeah?
XXXX: Please- (Pause) -just stop, I've had enough, you can't kill-
Dr: Quiet down now, last one and then we can put you to sleep, better get it down than postpone it.
XXXX: Fuck you! I swear to god if you even try to gas me one more-
<SCP-XXXX exposed to lethal gas, loud screams of XXXX can before choking is heard and the sound of XXX struggling to be breath could be heard>
Dr: Okay okay, enough, shut it off and let him be, prep the sedatives and contact Liam to get down here with his boys to move it.
<Sound of fans turning on and XXXX struggling turns to deep breaths>
Dr: SCP-XXXX, are you still alive?
XXXX: You damn bitch! I swear to god if you keep this shit up i'm gonna-
<Dr ██████ turns off audio output from test chamber>
Dr: Okay, seems were all done, we'll continue testing tomorrow, Dr ██████ out.
<End of audio transmission segment>

Test-E - ██/██/████
Subject: SCP-XXXX
Procedure: Test foundation firearms that can be moved into a test chamber and discharge weapons against it to seem how it will react to foundation small arms and heavy weapons whilst SCP-XXX is restrained and unable to escape. Operators of the weapons will be under strict orders by Dr ██████ to only target the head or the inner chest.
Results: Test 90% completed before SCP-XXXX broke through restraints and escaped.
Analysis by Dr █████████: Progress at first was smooth, foundation weaponry proved to be capable of penetrating the subjects exterior however, when moving onto a heavy machine gun, operators managed to dismember the right arm from the subject by hitting the shoulder of the subject with a fifty caliber round and popping the shoulder, separating the arm from the main body. This enraged the subject and it re-positioned it's arm for it to regrow clear from it's predecessor before regrowing the entire arm in approximately 7 seconds which it then used to increase it's density and break through it's restraints. SCP-XXXX soon killed Dr ██████, SGT ████████, CPL █████ and 8 other security personal before being sedated. Dr █████████ is now in charge overseeing research upon SCP-XXXX.

Audio transition log: 00:00:00-00:04:34

Doctor █████████ will be interviewing XXXX, addressing it as "Tiger" due to the SCP's preference of name rather than it's number.
Dr: Good morning Tiger, can you hear me well?
<Silence for a moment>
Dr: Tiger, can you hear me?
<SCP-XXXX can be heard disgruntled>
Dr: I'll take that as a yes, i just wish to talk to you so i myself can get to know you better.
XXXX: Well what is there to talk about?
Dr: Well, maybe we could talk a bit about your personal life before the foundation found you in (Redacted).
XXXX: I don't wish to talk about that.
Dr: But, i wished to learn more about you personally-
XXXX: Then ask something else then.
Dr: Well- (Slight pause) -how did you get your current name, "Tiger" that is.
<SCP-XXXX takes a small pause before speaking up>
XXXX: I earn't the name in the Army.
Dr: The United States Army i presume?
XXXX: Correct.
Dr: Well, i presume you have a file then which i could read-
XXXX: No!
Dr: I'm sorry?
XXXX: You won't find a file on me.
Dr: And why's that?
<No response from SCP-XXXX>
Dr: Tiger, please tell me why i wouldn't find a file on you?
<No response from SCP-XXXX>
Dr: XXXX, i can easily have your radio privileges revoked and stop conversations with personal on duty to make your containment here as bleak as possible.
XXXX: ███████ ███ ██████████ ███████ ██.
Dr: Oh, this took an unexpected turn. Very well, good day Tiger.

<No response from SCP-XXXX>
Dr: XXXX, i can easily have your radio privileges revoked and stop conversations with personal on duty to make your containment here as bleak as possible.
XXXX: Because the Foundation destroyed it.
Dr: Oh, this took an unexpected turn. Very well, good day Tiger.
<End log>

Analysis by 05:Subject is presumed to have previous connections with the foundation, requesting that a higher authority search the archive for articles related to SCP-XXXX. Dr Valentine and security officers present during the interview have been administered class A amnestics in order to contain this information.

C-XXXX-3
Case: B-XXXX-9: Level 5 personal have planned a interview with SCP-XXXX to be conducted at 2/07/2019 due to the events of interview-9 (B-XXXX-9). Dr Valentine will be exempt from the interview with a D-class to take his place as the interviewer. Facility guards will be required to not be in the same room as the D-class when the interview takes place however will be required to be on standby in the case the subject attempts to breach containment. When interview is completed D-class is to be taken into isolated custody and to have zero contact with any personal. Audio log and audio transition log is to be reviewed by 05 personal only to seek approval before being archived for 03 access.

B-XXXX-10

D-9845 (D) will be interviewing SCP-XXXX (XXXX) in an attempt to learn what knowledge SCP-XXXX has with the foundation.

D: Uh, h-hello?
XXXX: Hello, you sound different.
D: Y-yes well that is because i am your temporary interviewer.
XXXX: Why did the previous egghead lose the will to live?
D: I don't know, I've been told to ask your questions regarding information about the SCP Foundation-
XXXX: All i know is that they burned my military file.
D: -and in exchange for your compliance, the foundation is willing to grant a request of your personal choice as a reward for your efforts.
XXXX: And if i refuse to comply?
D: Uh- (D-9845 goes through notes) -uh it says that if you fail to comply then your privileges will be revoked, this means your radio access, loss of furniture within your container and-
XXXX: Yeah yeah i get it, make my existence a bore. (Subject pauses to think for a moment) Okay, what's the first question?
D: Okay well, how did you come into first contact with the SCP Foundation?
XXXX: One of your agents approached me and offered me a role at the foundation, i accepted and become part of a MTF unit to which i was later transferred to a different MTF unit.
D: Oh uh- (D-9845 goes through notes again) -okay thanks um, i'm not sure how to respond to that. I think we'll go onto the next quest-
XXXX: Tell me, what clothes are you wearing?
D: W-what?
XXXX: Your clothes, tell me, are you wearing by any chance a orange jumpsuit?
D: Y-yes?
XXXX: (Laughs) Oh you poor bastard, i guess the shadowy pricks figured something out, eh?
D: I'm sorry i don't understand what you mean, can you uh, clarify for me what you-
XXXX: I'm sorry kid, your going to die after this interview.
D: W-what do you mean? Your going to kill me?
XXXX: Not me, the Council.
D: W-why?
XXXX: It doesn't matter, best make your death not be in vain and let me explain-
D: Hey, guys, let me out- (D-9845 stands and attempts to leave the monitoring room above subjects container) -this isn't funny! Let me-
<Audio input for SCP-XXXX's monitoring room disabled. Encrypted line accepted, code name "Secret">
XXXX: Kid? You there?
Secret: The D-class will, as you said, die after this interview, however i am most interested as to how you know of us.
XXXX: What the fuck are you?
Secret: I asked a question SCP-XXXX, answer it!
XXXX: Your- (Slight pause) -one of them, i helped you people! I trusted you! And you betrayed me! (SCP-XXXX now angered) I helped you do your dirty work! I did whatever you told me and then you-
Secret: At ease Sergeant Tiger or should i address you by your designation Alpha one twelve? (A-1-12)
XXXX: So you know who i am-
Secret: And what happened, it seems a warhead wasn't enough to take you down with Area-11 and all the other anomalies within.
XXXX: You bastards fucked me up! You turned me into a monster!
Secret: Accidents happen Sergeant, it seems you were just one of the many others that happen. However, you may prove to be of other use to us through the benefits of science, how exciting is that?
XXXX: I'll kill anyone who-
<Audio input within SCP-XXXX's container disabled by encrypted line>
Secret: I apologize on behalf of the Foundation for the potential suffering you will endure however you are now on the their side which simply doesn't work for us, task force wise that is. In the meantime SCP-XXXX, i am a man of my word and will grant you a request, at my approved permission of cause. Goodbye Sergeant, it has been nice talking to you again.

C-XXXX-4:
Case: B-XXXX-10: Subject breached containment by increasing mass beyond previously recorded data. SCP-XXXX smashed it's way out of it's container and proceeded to cause damage to Site-88's underground section and proceeded to make it's way to the surface. When it reached the surface it was then able to be targeted by Site-88's 4 APC's which caused enough damage for exposed segments of SCP-XXXX to be visible which allowed security personal to sedate SCP-XXXX by tranquilize darts. SCP-XXXX was re-contained and kept it in it's secondary container under constant sedation before being moved to Area-50 for further experimentation and for more capable security forces to prevent SCP-XXXX from escaping the area in the case of another containment breach.
