Alright let's give a critique:
Item Number: SCP-xxxx
This should be "Item #:" and "SCP-xxxx" doesn't need to be bold.
Object Class: Thaumial
It's spelt "Thaumiel" and again Thaumiel doesn't need to be bold.
SCP-xxxx is allowed to freely protect, be an interviewer, or help out at Site-█████.
Even for a Thaumiel scip, unless this is specifically related to what the SCP is Thaumiel for or related to its containment, this wouldn't happen.
SCP-xxxx must be given at least 2KG of any form of protein daily.
That is horrendously vague.
SCP-xxxx is always allowed into the on-site gym, but is to be asked to leave at 9:30 PM, so SCP-xxxx does not break any equipment.
See my point above the previous one.
SCP-xxxx lives in Site-█████. SCP-xxxx's apartment
Apartment? What apartment? Is this site just a tower block?
consists of a King sized bed, 2 medium sized lamps, 1 work desk, 1 desk lamp, work desk equipment, 1 armoury cabinet, 1 large refrigerator/ freezer, high quality A/C, 1 medium radiator, 1 medium strength roof light, 1 potted plant, 1 wardrobe and 1 large air freshener.
Again, unless this is specifically related to why this SCP is thaumiel or to its containment, wouldn't happen.
SCP-xxxx is a Caucasian male, 2 metres and 3" tall,
You're only supposed to use metric measurements, not imperial and just a side note, using both at the same time is never done anywhere. It's bizarre.
weighs 90 KG 1. 18.89 Stone or 264.55 Pounds
You don't need to convert how much this is into stone. You use metric measurements and only metric measurements.
SCP-xxxx is apart of the MTF Unit ULTRA-123
You are not using the correct MTF naming convention. Please see the guide here: http://www.scp-wiki.net/task-forces
Also don't put 2 footnotes right next to each other. This is never done, is confusing and jsut looks silly.
On the subject of these footnotes:
AKA Black Arrow, Black Arrow's symbol is here on http://oi67.tinypic.com/330tixv.jpg and the ultra symbol is here on http://img09.deviantart.net/d95f/i/2014/003/4/8/ultramarines_chapter_badge_by_drdraze-d70pslv.png
1. Why is this relevant information?
2. Again you're not using the correct MTF naming convention
3. It's unlikely you actually own these images but even if you did, the Foundation would not link to deviantart in a top secret scientific document
ULTRA ranking came from when SCP-xxxx said that none of the MTF units were up to his standards. First we had no idea what he could be apart of, until we SCP-xxxx proposed the idea of ULTRA-1.
Are you saying the SCP said no MTF units were to its liking? Well no shit, it's a Mobile Task Force, I can't imagine any SCP likes MTF's. I can't see in any situation the Foundation saying "well we better change it to a more likeable one then"
SCP-xxxx posses supernatural strength, being capable of lifting a minimum 5,000 tonnes. Speed of SCP-xxxx has be recorded at Mach 504 but SCP-xxxx has bragged that he can go up to Mach 2005, but no evidence shows that SCP-xxxx can reach that level speed. SCP-xxxx is also immune to all cognito hazards, because of scaring events that happened in his past. Cells of SCP-xxxx can not be replicated/copied by any means know, even SCPs that possess the ability.
This is boring. This is just a generic X-Man SCP.
Due to SCP-xxxx's incredible feats, some researchers think that SCP-xxxx is a descendant of a god or even a demi-god most noticeable Hercules/ Heracles, but no evidence supports the proposal.
Oh come on, this is taking the biscuit. No scientist would ever say "we think it's the descendant of a god" without actual evidence. Also you do realise Hercules wasn't real right?
If SCP-xxxx is to not consume 2KG or more of protein within 24 hours, it will become aggravated until the sufficient amount of protein is consumed by SCP-xxxx, it will become docile.
Why?
I don't think there's really any point in me going through what I assume is meant to be the Addendum.
This is really bad. It's a generic X-Man that for no reason whatsoever is Thaumiel and is allowed to do whatever it wants.
This shows a clear lack of understanding about what makes a Thaumiel SCP and in all honesty this draft shows a lack of understanding about SCP in general. There's grammar mistakes, formatting issues and tone issues.
This idea will not work, ever. My only advice here is that you should go back to the "how to write an SCP" guide (http://www.scp-wiki.net/how-to-write-an-scp) and also reading more SCP articles would help. I would also recommend running your ideas past the ideas and brainstorming forum before writing a draft.
The idea of an SCP article is to make something anomalous that is interesting. Not just a generic "Superman that is friend of the Foundation"
