Description
Scp-4000 appears to be a 1500square foot trailer appearing to match the models of smiliar trailers made in the 1960s. The outside of scp-4000 is rusted and worn down looking. Only coming into the foundations radar after mutiple missing persons reports led to a trailer, with doors and windows which would not break or open. From the outside , scp-4000 appears to have an old emptied interior. Showing no signs of being occupied in years. Scp-4000 will open. But this only happens when one personnel is entering. Heavy statick covers any sound or video collected from inside scp-4000. But after an hour or so, the electronics used to record scp-4000 are returned, fully able to show what happened to the personnel that entered. After entering, personnel video shows the interior of scp-4000 to be nearly fully furnished, furnished as a 2010 home, plumbing and even lighting still working. But any attempt at contacting the outside world appears to be useless. After 24 hours, the video taken from inside the scp, now shows the fate of the personnel, unlike before. When which it did not. After 12 hours of being inside scp-4000 , personnel start to run around the trailer, trying to break windows and escape. Then, all panic stops, as a seemlessly innocent kitten walks over to the personnel, and after playing with the kitten, now known as scp-4000 b. It will cuddle the personnel, causing the person to sleep. And as soon as sleep occurs, scp-4000 b turns into a much more grotesque looking feline. Puss coming from it's oraphises and sharp knife like claws and teeth, this is when scp-4000 b proceeds to kill the human. Taking the corpse to one of scp-4000s rooms. Doctors who have studied this believe that scp-4000 uses scp b in a symbiotic relationship. Scp b calms the victims then kills them, while scp-4000 despises, and supposedly consumed the organic matter of the corpses
Scp-4000 and scp-4000 b are not allowed to interact with any other scps. As with cases, safe class scps have been reported to be killed or destroyed by scp-4000. Anyone within 20 feet of the scp have had a strong compulsion to explore the trailer, which would lead to their death. No experiments with scps higher than safe class have been done. And no more scps are allowed near 4000, the scp seems to have somewhat intelligence. Able to communicate using the video that is taken of it, scp appears to relish in showing others what it has done to the mental states of it's victims, put into simple terms. Scp 4000 and scp-4000 b both have the personality traits of physchopaths
