Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures:
SCP-XXXX is to be locked in a 6m x 6m x 6m containment cell, with one small glass section, visible from the viewing area. SCP-XXXX is to be locked in it's containment cell at all times, under no circumstance. SCP-XXXX is to be monitored by two (2) armed security officers at all times, one should be armed with their main firearm and a tranquilizer dart.
The SCP is to be monitored via the camera placed on the viewing side of the pane every 30 minutes.
Description:
SCP-XXXX is a humanoid entity, measuring 2.1 meters in height. SCP-XXXX harbours all the capabilities to be classed humanoid, besides the fact of it's three heads. The central head is the only one that the SCP has been recorded speaking out of. X-Ray's have shown that the SCP has all the human organs within the central head. SCP-XXXX has no organs in any other head, however is able to move them.
SCP-XXXX harbours the ability to release a sort of saliva, which is enough to knock out (some cases the subject holds zero ability to work anything, and basic functions are failing) any human subject. When any human subject is unconscious to the saliva, SCP-XXXX approaches the unconscious subject, then retreats to it's "safe zone" (which has been observed as a flat surface to place the subject on). The reason for this behaviour is unknown, however approximately two and a half hours later, the human subject has regained conscious, and SCP-XXXX no longer has anything to do with said subject (Follow Addendum XXXX-2 for further knowledge behind said behaviour.)
Addendum XXXX-1:
The following is the actions after the first recorded speech of SCP-XXXX, recorded by Security Officers ███████ and ████████ and the on-scene camera. This is the first interview, conducted by Doctor ███.
Interviewed: SCP-XXXX
Interviewer: Doctor ███
Foreword: SCP-XXXX's speech ability is to be discovered further within this interview. Doctor ███ was alerted by Security Officer ███████'s supervisor, after the officer reported SCP-XXXX speaking fluent English. The interview was conducted via a microphone placed on the SCP's control panel, and a microphone placed secretly inside the cell via roof access.
<Begin Log>
Interviewer: Rifling through papers is heard over the footage. Hello, SCP-XXXX. Do you hear me?
SCP-XXXX: SCP-XXXX is visibly startled. I didn't invite a visitor. I can hear you, though.
Interviewer: You don't invite us. Good. A sudden pause is heard as Dr ███ takes a fast note, which read "Subject withholds perfect ability to speak." We invite you.
SCP-XXXX: You don't invite someone to their own.. hotel. Now. Where the hell is the cafeteria? I'm starved.
Interviewer: I.. We.. We weren't aware you required food and such. We thought you'd be like the rest-
SCP-XXXX: Is this because of my heads? I swear, if it is..
Interviewer: Wait. About your.. heads as you said. Do you know where they came from?
SCP-XXXX: Of course I do. It's just like me asking do you know where YOU came from. You'd say your [DATA EXPUNGED].
Interviewer: Honestly.. I'm surprised you know so much about the human skeleton.
SCP-XXXX: Well.. surprise? My heads. There's a.. poor reason for them. Care for me to, maybe start?
Interviewer: I'm all ears.
SCP-XXXX: Well.. it really started a while back. I liked to roam the land, exploring. Your kind were.. so grateful for me. I say your kind, except.. they didn't lock me up. They worshipped me. As if I was God. I felt so.. powerful. I felt like I had an entire race under my command. It was.. it was good. Each head, surprise, came at a different time to another. This one, SCP-XXXX points to it's left head, before continuing, came on ██/█/████. The other, came on █/██/████. They came after the race.. betrayed me. You see, a new group, arrived. Unlike the race I was God to. They blinded my heads.. then took them off and I was here. Now here I am.
Interviewer: I'm going to clear this up.. the heads you're currently.. harbouring.. came within two weeks of each other? What the fuck was happening?
SCP-XXXX: The race I.. was God to. They thought to.. decorate me with the heads of their enemies.
Interviewer: Each head though, look the same. What's the reasoning behind that?
SCP-XXXX: SCP-XXXX's attitude suddenly changes to a more aggressive one. Did anyone ever tell you that you ask too many fucking questions? I'm done for today.
A silence lasting 74 seconds ensues.
Interviewer: I see. Why are you.. agitated-
SCP-XXXX: I swear I said I'm done for today. Now get the fuck away!
<End Log.>Closing Statement: SCP-XXXX answered a few questions without growing suddenly agitated, forcing the interview off. Doctor ███ remarked the following. "I've never seen an attitude in an SCP just change so suddenly. I suggest further testing."
Addendum SCP-XXXX-2:
The following is a test log given by Doctor ███ and Researcher ███████. Four (4) Security Officers and Sergeant ████ were also present.
Test XXXX-1 - 13/1/████
Subject: SCP-XXXX's Anomalous & Dangerous Behaviour
Procedure: SCP-XXXX was given D-9191 on 13/1/████ at ██:51 PM. The subject was forced in by Security Officers, and about 6 seconds later, a scream is heard from the D-Class. Doctor ███ and the other people present wait two (2) hours and fifty-three (53) minutes, until knocking is heard from the door. During this time, security officers monitor the camera to see that SCP-XXXX was performing a sort of surgery, however it removed all organs except the heart and brain. It also placed an orange jacket over the D-Class, before placing the organs in a bag and storing it in the jacket. SCP-XXXX then proceeds to knock on the door before saying, "It's done. You can get the forgiven out."
Results: SCP-XXXX's saliva origin is theorised by the Researcher. ███████ quotes, "That thing's spit. It comes from the.. the.. the saliva he found from the subject he did that on.. Doctor.. I think I'll let you discover the rest.." It is also discovered why the SCP lets some people go without saying a word.
Analysis: Doctor ███ reviewed the tape with Researcher ███████ that night. Doctor ███ realises that D-9191 harbours the ability to move around, but not the ability to speak. He turns the recording off directly before D-9191's termination.
Addendum XXXX-3:
On 16/1/████, Doctor ███ is found dead by other personnel. His sudden death is startling, and a cause cannot be certain. An investigation is launched.
Addendum XXXX-4:
Date: 17/1/████. Researcher ███████ is escorted away from his duties by Agent ████████. The Researcher is to be interviewed by the Agent.
Interviewed: Researcher ███████ (Hereby referred to as "Max")
Interviewer: Agent ████████
Foreword: Researcher ███████ is being interviewed by the [REDACTED] Agent to discover a possible cause of death, and what possibly could've happened within the three days.
<Begin Log>
Agent ████████: Alright, ███████. Would you like a cup of water or anything?
"Max": No.. thank you.
Agent: Alright. Interview has begun, █:15 PM, 17th of January, ████. Mr. ████████, or do you wish us to call you your codename?
"Max": Codename, please..
Agent: Alright, "Max". What happened on the 16th of January?
"Max": N-nothing out of the ordinary.. We didn't see eachother that day. The last contact I had with Doctor ███ was on the thirteenth. Test day.
Agent: What happened after the test up to your last contact.
"Max": Well, it was like █ o'clock in the evening so we had our own duties to finish. I had something in the science bay, Doctor ███ had to write up his report. Then, that night. We went to our bunk. Me and him share one, damn bunk beds are shit. Anyways. We reviewed the tape that he copied. He had Sergeant ████'s permission. After reviewing it, we went to sleep. I saw him each morning and night after that, but no direct speech. We had our own duties.
Agent: Alright, "Max". I'm just going to clear this up before I finish the interview. When you woke up on the sixteenth, you woke up and the doctor was dead?
"Max": Yes, sir.
Agent: Alright then. We're done here. You may leave.
"Max" slipped the chair back and left the room. Agent ████████ quoted the following before leaving.
Agent: I request [REDACTED] Agents disguise as personnel and follow the Researcher for the next seven days. I have a suspicion he was involved.. that or the SCP. With that in mind, I request all tests on SCP-XXXX be halted until further notice under the order of the [REDCATED]. Interview over.
<End Log>Closing Statement: Agent ████████'s request was acknowledged by O5-█, and permission for both was granted. Scientific personnel were alerted of the halt, including "Max". Agent ████ has disguised as a scientific researcher with the same clearance and such of "Max" after agreement with the Director of Scientific Operations.
Addendum XXXX-5:
On 20/1/████, Researcher "Max" ███████ was found dead by personnel. Quotes of him being found dead in the same position as Doctor ███ were relayed by personnel. A test was decided to occur under the orders of Agent ████████ and the [REDACTED].
Test XXXX-2 - 22/1/████
Subject: Second test of SCP-XXXX. This test is to receive information about the death.
Procedure: D-9213, D-8712 and D-8713 were given to Doctor Hevy █████████. Doctor Hevy's test was supervised by Agent ████████, and 'Researcher' "Alf" (Agent ████). D-9213 enters the containment zone, and SCP-XXXX behaves similar to what happened in Test XXXX-1 on 13/1/████. A new wait time is recorded, of three (3) hours and fifteen (15) minutes. D-9213 exits the containment cell, and SCP-XXXX returns to the table supplied by Foundation Personnel, and immediately says. "I sense two more. Show them." The test is concluded at ██:04. D-9213 is terminated under view of Agent ████. D-8712 and 8713 are given a tape recording and told to watch the whole thing through. Doctor Hevy ensures they watch the three and a quarter hour footage.
Results: The D-Class, when watching, are given the quote that Researcher ███████ gave to Doctor ███ on the thirteenth of January. D-8713 remarks, "Th-the guy that died.. his theory is.. is true. Will we die now..?" Doctor Hevy assures them the opposite to death, and a three-five day wait is established.
Analysis: Doctor Hevy reports to his 'colleague', 'Researcher Alf'. The Agent acknowledges what was said from the Doctor, and reports to Agent ████████. Both agents begin to theorise what happened, and a "temporary" cause of death. It is determined SCP-XXXX harbours ability to cause mental difficulties to those who review it. This temporary cause will be turned to definite in three-five days.
Addendum XXXX-6:
D-8712 dies on 26/1/████ in early hours. D-8712 is found in the same death position as Researcher ███████ and Doctor ███. A cause of death for all three (3) victims is established as "mental hazard upon SCP-XXXX." SCP-XXXX's testing remains halted until a bypass to this issue can be found.
Addendum XXXX-6-B:
D-8713 is found dead on 30/1/████. The cause of death is SCP-XXXX's mental anomalous behaviour. Agent ████ and Doctor Hevy is monitored by health staff for the next 14 days.
