Item #: IT
Object Class: Keter
Special Containment Procedures: IT is to be contained within a reinforced titanium 100 x 100 square meter room (as IT does not settle on any particular form the room must be large for it to change forms) filled with a nerve gas that proceeds to weaken IT's strength/power.
Whilst cleaning IT's room, D-Class must stay as far away from IT as possible. Usually IT lets D-Class live while they clean the room from blood spilt by some of IT's forms. Unfortunately, IT does not let the D-Class leave, as the D-Class walk to the exit of the containment, IT reaches out a tentacle from the form of an odd mutation of an octopus, crushes the D-Class's ribcage and drops it on the floor. Guards report that the next day there is no proof that the body of the D-Class was ever there, there is no footage, no body, no blood.
Description: There currently is not much description of the physical appearance of IT for it rapidly changes forms and appearances. IT seems to be able to take form of anything, even unknown species, mutations, objects, liquids, animals, people TRUST NOTHING. IT's most common appearance is a young boy with a lack of ears, nose, wrinkles, fingerprints and instead of eyes it only has red iris's.
IT can edit any information about itself, either physically or online. IT is seemingly impenetrable, the SCP foundation has tried thousands of methods including: lasers; other SCP's; explosions and extremely sharp objects. All of these attempts have proven a waste of time. IT hates being called by it's SCP name and constantly says "If you wish to call me something, call me by my name." To this day we have no clue what IT's name is. When IT edits information of itself it will always remove it's SCP name and replace it with 'IT', if there is any proof of IT changing information of itself then please do nothing for your own good :-). If any foundation personnel call IT by it's SCP name then it will promptly breach containment and BRUTALLY MURDER the staff that call it that name.
IT has breached containment than any other SCP at site-621 and has killed more than any other SCP at its current site. During it's breaches IT has killed foundation personnel in many ways including: evaporation; no known reason of death; stabbing, disintegration; hunger; thirst; burning; freezing and missing body parts. Some guards have randomly disappeared during IT's containment breaches and are presumed to be killed as they have never been seen since.
Discovery: IT was discovered at a sports field in the appearance of a knife wielding runner. The runner IT appeared as was a [REDACTED]2 who was supposed to be running the 800 meter at the very same sports field that day. It is presumed that [REDACTED] was killed by IT earlier that day and that IT stole the runner's appearance to be disguised but upon the police arriving at the scene, IT then transformed into a pale, humanoid creature with a mouth filled with an estimated total of 17 rows of bloodied teeth, IT proceeded to devour almost every single person at the field until it was later detained and brought into containment.
Behaviour: The behaviour of IT is random, it does not have a daily pattern or routine. IT is not fed for it does not need to eat yet it will happily eat what it can, the same is with drinking. IT does not enjoy talking to foundation personnel yet it does occasionally mutters a phrase that is estimated to be ""Death Lives". The foundation has tried to add a microphone to containment but to no avail, IT refuses to talk or be interviewed by foundation personnel.
