SCP-NUMBERS

Item #: SCP-N

Object Class: Keter

Special Containment Procedures: [This SCP can be contained only if there is nothing related to numbers around, this includes amount of things around him, to contain it we use a completely hollow universe and has no oxygen molecules or any other type of molecule.]

Description: When it is contained it acts as a void, but, if its NOT contained it can warp reality in a way that it will multiplicate the amount of matter around it, so, if not contained, it could erase you, clone you, slice you in half or even delete reality.
It doesn't need any oxygen to survive.

Addendum: The entity choose not to delete reality, but it could.
