Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: As of 10/11/19██, SCP-XXXX is uncontainable, due to its effects on probability, but has shown to prefer to stay near Site-███, ████████, USA and ███████, Japan. SCP-XXXX is now successfully contained at Site-███. SCP-XXXX is locked in an empty storage (henceforth SCP-XXXX’s containment cell) locker in Site-███. (see Addendum XXXX-3) No personnel are to unlock the door to the SCP-XXXX’s containment cell except to clean it, but once unlocked, the cell must be relocked as soon as possible.
SCP-XXXX’s cell’s cleaning should be done by two (2) C class personnel, and they shall not acknowledge SCP-XXXX’s existence, as it can cause an SCP-XXXX-1 event, even if she attacks them. In the event of hostility from SCP-XXXX, personnel shall both take the cyanide tablet that command gives them.
Description: SCP-XXXX is an ordinary looking humanoid female, with a height of five (5) feet, three (3) inches, and a weight of ninety seven (97) pounds, five (5) ounces. SCP-XXXX will only respond to the name “Samantha”, though it is unclear if this is from anomalous effects, or her being stubborn.
SCP-XXXX’s anomalous effects manifest when it encounters anything with a probability. (regardless of how high of a probability) (see Addendum XXXX-1)
When met with any a valid probability, SCP-XXXX will spontaneously create several localized timelines that show what could happen in the localized area. (from now on called SCP-XXXX-1 events) SCP-XXXX-1 events are viewable from the outside, though mainstream science says this should be impossible.. SCP-XXXX then will choose (the process for this is unknown, as SCP-XXXX, and anyone in the localized timeline, is in a warp in space-time that will leave affected subjects with no memory of the event) a specified timeline, usually beneficial to SCP-XXXX, and it will occur, and as outside changes can change what occurs, there is no way to stop it from picking a beneficial (that is relative to events, as it could mean that she gets away, (from us in most cases) or she gains control of classified documents) timeline, and any effects from outside will cause another SCP-XXXX-1 event.
Addendum XXXX-1: Testing SCP-XXXX’s anomalous effects has shown that SCP-XXXX-1 events will not occur with probabilities under a .1% chance of occurance
Addendum XXXX-2: Further testing SCP-XXXX's anomalous effects on itself and other people has determined that all probabilities that activate SCP-XXXX's effects do not come from SCP-XXXX, but SCP-XXXX's probabilities are then transferred to each possibility to make the anomaly. (3/19/20██)
Addendum XXXX-3: (6/25/201█) Dr. ███████ decided to try a theory that extended what research found on 3/19/20██, by locking SCP-XXXX in an abandoned storage locker in Site-██'s Sub Level 3 storage. After telling her to fetch him a box from there, (as she was very helpful to the researchers, though she always had an assigned member of Security with her) and when she walked in, Security Member, █████ locked the door behind SCP-XXXX. SCP-XXXX, is a normal human as long as probability does not touch her, so she is effectively contained.
