Author note: Big SCP, always wanted to contribute but never had a decent idea until now, as far as my research shows there's no SCP like this other than SCP-1499 in which the only similarity they share is the fact they're gas masks. Other than that i think this is a very original idea. I'm open to critique but hoping for a green light this is my fist draft. I'd also like to add interactions with other SCPs and this one in the future. Thanks for your time.)
SCP-???? (to be numbered)
Object Class: Safe
Special Containment Procedures:
SCP-???? is to be contained in a standard safe-class, anomalous object storage vault.
Removal from storage will only be granted for testing purposes by level-4 personal.
All personal subject to testing/use of SCP-???? will receive a full physical exam (including optical and audiometry testing) before testing/use of SCP-???? and immediately following SCP-????s removal from the subject.
Records of all results to be copied, documented and stored.
Description:
SCP-???? appears as a regular [REDACTED] brand, full facial respirator mask.
SCP-???? holds unique properties than all other respirators sharing its batch number and model.
SCP-???? appears to self clean and self repair damage sustained over time eg. broken straps, scratched/cracked visor, ect.
SCP-???? appears and functions as a regular respiratory mask until its user comes into contact with another SCP. Be they an object, humanoid, inter-dimensional or otherwise, other SCPs become highlighted by a slight glow through the lens of SCP-????s visor whether regularly visible or not.
The wearer will also experience a form of immunity from all other SCPs (see addendum list for further details).
Forms of immunity to other SCPs have in summery manifested in ways such as:
- Complete invisibility, deafness and general lack of awareness of users presence. (This includes photographic, video and audio recordings of a subject wearing SCP-???? at the time of recording, while remaining plainly visible to human eyes through all mediums including the naked eye)
- Immunity to unique effects of skin-contact, visual contact, audio contact.
- A numbness to pain/injury received while wearing SCP-???? (Though these effects still manifest upon removal of the mask and lethal damage may kill a subject while wearing SCP-????).
[SCP-???? would be a perfect research tool for the Foundation if not for its draw backs.]
SCPs are capable of awareness of both SCP-???? and its user if a user attempts to put on or remove SCP-???? while in a sight or audible range.
SCP-????s real danger is limited to its user who suffers a heavy cost for the protection SCP-???? provides.
Subjects have suffered deterioration/loss of sight, hearing, movement and ability to smell, that is directly proportionate to the level (time/degree) of exposure to other SCPs and the level of protection offered to the user. If no exposure to other SCPs is present during use, minor deterioration of the senses will occur after an hours use and worsening with fifteen minute intervals from then on.
Sensory deterioration occurs only once SCP-???? is removed.
Sensory deterioration due to prolonged use begins barely noticeable to the user and they may not even voice complaints or concerns. All subjects have complained after a personal collective time of use of one hour fifteen minutes be it any singular or combination of their senses.
It appears even prolonged breaks will not reset your clock with SCP-????
Curiously, all deteriorated/lost senses return to the state they were originally in upon first contact with SCP-????, upon the subjects re-donning of SCP-????.
It is suspected this is SCP-????s way to secure its use in the future. While not sentient, SCP-???? appears to have a desire to be used, hence its useful nature and reimbursement of stolen senses upon re-use, enticing subjects desire to live in the world they once knew, while being protected from more sinister SCPs and pain.
It is for this reason, research purposes of SCP-????s use has been denied until further testing is conducted.
Addendum listings of notice (summarized):
001: Discovery of SCP-???? occurred during a early reaction to a report of a possible SCP-020 infestation.
Upon confirmation of SCP-020s presence, a team was sent in to contain the spread of SCP-020.
[REDACTED], a level 3 personal member of the team, kitted with a standard issue [REDACTED] respiratory mask claimed to see SCP-020 with his naked eye.
Shortly afterward, unable to explain the phenomena, another foundation member was called in and asked to identify the places SCP-020 had infected without any prior knowledge of infected materials.
Once given [REDACTED] respirator mask, the subject was able to identify all presence of SCP-020 with his naked eye. Upon [REDACTED] removal of his mask, he complained of blurred vision, its most recent user made no such remarks.
Confirmation of the masks unique properties quickly caused a worldwide recall of all [REDACTED] brand model respirators only to find none matched the capability of SCP-???? and the mask (now branded SCP-????) was brought back to the foundation for testing.
