SCP Foundation

All right Frayjais, gonna do a line by line here then give you my overall thoughts on the draft. These comments, aside from the overview, will be made as I'm reading.

SCP-XXXX is to be contained in a 1.8m x 2.4m room

These are some extremely specific dimensions, is there any reason for them to be this way? If not, they don't need to be included in the article. If so, what purpose does this serve?

SCP-XXXX can be used only in cases of extreme mental deterioration, and must be monitored by at least 3 other individuals.

Under what circumstances? Testing? What kind of testing is occurring here?

SCP-XXXX is a Caucasian male measuring approximately 1.8m tall and weighing 150Lb.

Lbs are not SI (metric) so you might want to fix this.

Specimen has often referred to himself as "Friend" or "Brother".

Use it rather than he/she/they when referring to SCP objects. Also, is it saying that it's a friend/brother or that its name is Friend/Brother? If it's the former option, it doesn't need to be capitalized and that could be specified.

SCP-XXXX shows extreme care and affection towards any sapient entity within its line of sight, often comforting them in times of stress, or through the use of compliments.

Why? What's the motive or the drive here? Why does it want to do these things? More importantly, how is this anomalous? Being overly friend is not anomalous.

SCP-XXXX is often used for comforting staff and agents who have frequently or recently dealt with dangerous specimens. It is important to note that SCP-XXXX seems to understand each individual on a very personal level the moment they are introduced.

Still not anomalous. I've met people and felt like I've known them my whole life right from the get go, that doesn't really explain what's going on here. Additionally, this seems very lolfoundation to me in the sense that the Foundation is allowing valuable personnel to come into contact with an anomalous entity. I don't see that happening at any point in time, especially not with a sapient humanoid.

Addendum XXXX-1 SCP-XXXX escaped captivity with the help of 3 foundation personnel. over █ confirmed dead, and ██ injured, with only half of these deaths caused directly by SCP-XXXX. It is currently unknown weather SCP-XXXX possesses memetic potential, however it is under testing.

weather -> whether

This also ties into why I don't see the Foundation doing what they did in the first place, it also doesn't explain why this entity was in containment to begin with. Also, I don't think memetic is the word you're going for here. Taken from Understanding Memetics:

Memetics deals with information transfer, specifically cultural information in society. The basic idea is to conflate the exchange of information between people with genetic material, to track the mutation of ideas as they are transmitted from one person to the next in the way you could track viral transmissions and mutations. However, a meme also provides benefits to the carrier if they spread it.

Meme : Memetics :: Gene : Genetics

Memetics does NOT refer to telepathy, ESP or any imaginary psychic mental magic. These words are memetic, and if you understand them then they are having a completely ordinary memetic effect on you.

Memetics in regards to SCP objects tends to focus on the impossible rather than the mundane, regarding effects that are transmitted via information. In general, the effects themselves should remain in the realm of information. A memetic SCP would be more likely to be a phrase that makes you think you have wings as opposed to a phrase that makes you actually grow a pair of wings. If you write up magic words that make people grow wings, it should be described as something other than memetic.

From what is provided here, I don't think this is what you're going for? If it is, can you explain why this hypothesis was reached (in the draft)? It's too vague otherwise.

Overall: Eh, I'm really not sure what's anomalous to begin with so I think that's something that would definitely need to be cleared up. A lot of the things written here don't really seem like things I could see the Foundation doing and the whole concept of "something the Foundation thought was nice, spent time with, then it all went poorly" has been done before many times, most notably by SCP-1048, and in more memorable ways.

If you're really set on making this idea work, I recommend you take it over to the Ideas and Brainstorming forum before you try to rework the article. Getting the concept fleshed out more and knowing which direction you want to take this from a narrative standpoint beforehand will make the writing process go a lot smoother.
