Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX is to be contained in a standard humanoid containment cell withing site-17. It is able to request entertainment in the form of music, art supplies and fiction books if his current physician deems the media non-harmful. Under no circumstances should SCP-XXXX have access to sharp objects outside of supervised testing.
Description: SCP-XXXX is a caucasian male of British decent appearing approximately 17 years old. It has black hair, dark eyes and exceptionally pale skin. The subject stands at 160cm and weighs approx. 72.6kg.
Heavy scarring has been recorded on XXXX's forearms, torso, and legs. Due to the nature of its anomaly, it is assumed that they are self-inflicted. Subject refuses to answer questions regarding the scars and will become agitated if the subject is further mentioned.
SCP-XXXX's mental capabilities are in line with what is expected of its age group while its physical capabilities are above average, being exceptionally strong and having high stamina.
SCP-XXXX has an extremely choleric temperament towards anyone over the mental age of 19. It will often refuse to cooperate with researchers unless a reward is offered, usually in the form of restricted food or entertainment. When it does cooperate, it will most likely do so while threatening, complaining about and/or insulting the closest adult figure.
When it is not being tested, SCP-XXXX will engage in mundane activities in its cell, such as drawing, reading, listening to music or otherwise engaging in whatever forms of entertainment that have been provided. It has expressed its intense dislike of captivity but has not attempted a breach since 19██ when he was first brought to the foundation.
SCP-XXXX is seemingly resistant to all forms of outside harm, be it natural causes or premeditated harm. This includes but is not limited to: Sharp objects, blunt force trauma, poisons, crushing, burning etc.
Any harmful action towards XXXX will glance off its skin, which is reported to cause a slight tingling sensation and mild pressure at worst while ingested or inhaled poisons are passed through its system the same way as regular food or gas. The only currently known exception to this anomaly is when harm is directly administered by XXXX's own hand, be it accidentally or with intent. In this situation, the damage is administered as it would be on a non-anomalous subject. Aside from physical resistance to harm, the specimen also seems at least partially resistant to mental effects from other SCPs.
It is currently unknown the full extent of the anomaly's full effect on the ageing process, though from observations thus far, biological functions seem to be considerably slowed. It's first reported sighting was 19██, which would place it far older than its assumed age. When asked about its age, SCP-XXXX will only ever say 17, no matter the year.
SCP-XXX's temperament changes dramatically in the presence of one or more children or child-like creatures with a mental age of 15 or below. SCP-XXXX will instantly become nurturing, friendly and extremely defensive of them. A bond of trust is formed very quickly, with even notably depressed or anxious children having a noticeable improvement in mood. It is unknown whether this effect is anomalous or rather a result of the subject's pleasant demeanour. SCP-XXXX will take part in games and activities with the children, even with an adult present.
At this stage, if any harm was to be directed at the children it was interacting with, it would go to extreme lengths to protect them, often shielding them with its own body, or charging at whatever was attempting to cause harm. One the perpetrator has either ceased their attack or has been rendered unable to move, SCP-XXXX will attempt to calm and reassure the children until they have returned to their regular activities.
Additional Notes: SCP-XXXX was brought to the foundation's attention on 24/0█/19██ after it protected a group of students at █████ Elementary School,████, United States. He was picked up by agents and taken to a local branch of the foundation but refused to answer any questions. After being transferred to Site-17 it breached containment on its first night and escaped the grounds. Searches of the nearby area revealed no sign of the subject.
Several years later in 20██ it revealed itself again when it was seen shielding two children from a car crash. It was again taken into custody with further precautions. It was noticeably more cooperative than it was in its first containment.
Addendum: As of 1█/██/20██ surveillance is to increase for SCP-XXXX. He has been showing signs of severe depression in our sessions. Due to his past signs of self-harm, we need to keep vigilant and make sure he doesn't do anything stupid.-Dr.S█████
Foreword: Soon after SCP-XXXX was returned to containment after its breach, it was questioned again by Dr. ████████ with much better results than the first round of questioning.
<Begin Log>
Dr.████████: For our first interview, this is common courtesy. Do you have a name?
SCP-XXXX: Yeah. Who doesn't? I'm Dominic.
Dr.████████: Nice to meet you, Dominic. Now then. I'm noticing that that isn't an American accent. It's more cockney than anything. How did you arrive here?
SCP-XXXX: Why would I tell you that? This is the second time you wankers have locked me up.
Dr.████████: It would help us get a grasp of your situation. We may be able to help you.
SCP-XXXX: Well I doubt that I'm getting out of here any time soon. You may as well hear it from the source.
Dr.████████: That would be very helpful, Dominic, thank you.
SCP-XXXX: Well then. Me and about 50 other tykes were shoved in a shipping container. I was probably about 7 at the time?. Sounds about right. Anyway, bout 10 of us made it to the US.
Dr.████████: I'm sorry that happened to you.
SCP-XXXX: Why? That was decades ago.
Dr.████████: How old are you, exactly?
SCP-XXXX: 17
Dr.████████: Anyway… What happened when you got to America?
SCP-XXXX: Well, by the end of it I was the only one left, and I was invincible. Look, I may be playing nice but that doesn't mean that I'm divulging all of my trauma to you, old man.
Dr.████████: Very well. If I may make one more assumption. Is that why you saved the children?
SCP-XXXX: Wow. What a guess. Look, they're kids. I can't let anyone else go through what I did. I'm not letting anyone else end up like this.
Dr.████████: A noble cause. Now then, guards, can you take SCP-XXXX to its cell?
<End Log>
Closing statement: SCP-XXXX attempted to resist containment, but was successfully locked in his cell. Footage showed him pacing the cell for the next several hours and scratching at his arms before going to bed.
Foreword: An accident during an experiment led to a child being mildly injured in the proximity of SCP-XXXX. His primary physician recorded their conversation during his check-up after the fact.

Dr.S█████: How are you feeling after yesterday, XXX? Any aches or pains?
SCP-XXXX: Take a guess.
Dr.S█████: If you answer my questions we can get you back to your room quicker, XXXX.
SCP-XXXX: And if you lot did your fucking job I wouldn't need to be here in the first place. Maybe if this place wasn't such a fucking joke neither of us would have to be here in the first place. If it wasn't such a joke an innocent kid wouldn't have gotten hurt.
Dr.S█████: I see where you're coming from, bud, but I really need to check that you're-
SCP-XXXX: I'm fine. I'll always be fine. Happy? Let me go back to my cell, dipshit.
<End Log>
Closing Statement: SCP-XXXX Was escorted back to its cell. It seemed agitated until it fell asleep, having been recorded pacing and frantically drawing the injured child along with several other images and notes.
Foreword: A day after the incident with the injured child, SCP-XXXX requested to meet with him under supervision and to give the child the drawings he had made. The request was granted.
<Begin Log>
SCP-XXXX: Hi there, buddy. How're you holding up?
███: I'm doing real good! They gave me a cool cast!"
SCP-XXXX: That makes you look very strong ███. Look, I drew something for you, to say sorry for not being able to keep you safe. I hope you like it.
███: It's me! Thank you"
SCP-XXXX: Now then. It's time to go now. You need to promise me that when you get home you'll rest and eat all your veggies so that arm heals up nicely, okay?
███: I will! I'll be as strong as you!
<Eng Log>
Closing statement: After the child left, SCP-XXXX went back to its cell without struggle and was visibly calmer than he was at the start of the day. Once in his cell, he resumed his usual activities.
