Item #: SCP-XXXX

Object Class: Keter Thaumiel

Special Containment Procedures: SCP-XXXX is to be contained in a standard humanoid cell in Site-██, on the lowest level of the facility. Armed Guards must be stationed outside of SCP-XXXX's cell at all times. Cameras and surveillance will be active at all times while the entity is contained. Hydraulic locks are required in the containment of SCP-XXXX. During transportation via truck convoy or aircraft only. SCP-XXXX must be sedated via IV and restrained by handcuffs on the arms and legs. Four armed guards wielding stun sticks must be present at all four sides of SCP-XXXX whilst in transport.

Description: SCP-XXXX is a dark crystalized humanoid figure, with a height of 1.9 meters. The entity is capable of mass homicide due to his enhanced strength, speed, agility, excellent use of weapons, and tactical advancement. The SCP has also been found on multiple occasions to change his skin material, though the science behind this is unknown. The SCP frequently talks about various wars he has fought in throughout history including but not limited to WW2, WW1, Revolutionary War, and the Crusades. SCP-XXXX has occurred in the modern world and has been apart of the downfall of major world leaderships, organizations, and governments.

The dark figure's past motives in terms of killing have been found invalid by interviewers. The entity has not stated any reason for mass murder of multiple MTF units and countless Foundation personnel. SCP-XXXX has not committed mass genocide on Foundation personnel since 2017, due to being conscripted for Foundation and Mobile Task Force use, therefore classifying the SCP as Thaumiel and removed from the Keter-Class.

The SCP has and is willing to cooperate with Mobile Task Forces, in aiding MTF in combat and recontainment operations. Failure to comply with the guidelines O5-██ set whilst SCP-XXXX was being conscripted, will result in SCP-XXXX's permanent containment at Site-██. If SCP-XXXX has complied with the operations and order from O5-██, will result in more benefits and leisurely activities around Foundation facilities and Operation Centers.

Discovery Log: SCP-XXXX was first discovered in a dense forest in Eastern Romania when the Foundation detected anomalous activity via satellite. When Mobile Task Force: Omega-12; was dispatched to the scene, the SCP had already vacated the area and the Foundation lost track of the dark figure. The Foundation caught and contained SCP-XXXX at a cabin, in Northern Utah. Mobile Task Force Teams transferred SCP-XXXX to Site-19 for questioning then moved to Site-██ for containment.

Interview 4587-1A

Interviewer: Dr. ████████

Interviewee: SCP-XXXX

Foreword: First interview ever conducted on SCP-XXXX, at Site-19.

<Begin Log, 09/09/2006 at 04:25>

Dr ████████: Hello, my name is Dr. ████████. What should I call you?

SCP-XXXX: Echo is fine, Doctor.

Dr. ████████: Very well then, Echo. Do you mind if I ask you a couple of questions?

SCP-XXXX: Considering you captured me in this filthy facility of yours, we might as well make use of this time.

Dr. ████████: Who exactly are you? We detected you on our satellites a couple of months ago and weren't able to contain you until now.

SCP-XXXX: I don't understand the question, Doctor.

Dr. ████████: Why be contained now? We're you waiting to be contained by us?

SCP-XXXX: Doctor, I have been evading your organization for a lifetime or two now. I have come to understand throughout the decades how your agents operate and the tactics that they use. How do you think I evaded you in Romania so quickly? Because you and your group of pansies were predictable.

Dr. ████████: Do you know why you are here?

SCP-XXXX: Because you don't want me out and about, all over the world. You are afraid of me, and you don't want the rest of the world to do the same.

Dr. ████████: Why did you kill those men in ████?

SCP-XXXX: Next question…

Dr. ████████: I need you to answer the question, Echo.

SCP-XXXX: I will not be answering that question, Doctor. I would suggest you mind your words, as your words can and will be twisted against you. (chuckles)

<End Log, 04:45>

Closing Statement: Dr. ████████ was unable to discover much about SCP-XXXX and therefore recommended the entity be labeled as a Keter-Class SCP and moved to Site-██ for further containment.

Medical Post-Op Checkup 013-1A

Medical Personnel: Dr. Steven Nelson,

Patient: SCP-XXXX "Echo"

Beginning Doctor's Notes: In the past, SCP-XXXX, has exhibited no abnormal mental or physical behavior. I have read his post-op report and he stated he entered a "rage emotional state that seemed to last forever".

Post Doctor Notes: I was unable to diagnose SCP-XXXX's mental or physical condition that causes him to enter his rage episode. Further research and possible testing may be necessary to come to a solid conclusion and to prevent any future incidents ]within Foundation facilities or operations where SCP-XXXX may be a danger to Foundation personnel. If any further research is inconclusive, I recommend that SCP-XXXX is moved into permanent containment and moved back to Object Class-Keter.
