Item #: SCP-1275
Object Class: Keter
Laconic Containment Procedures: Keep SCP-1275 in a tungsten cube filled with molten lead and an electrified wire lattice. Watch it from a distance. Capture it if it escapes, but don't get too close.
Laconic Description: SCP-1275 is a fluid blob that can move on its own, shows signs of intelligence, can change in size from as small as a marble to larger than a house, and can change in shape and appearance to look like anything.
It can't be felt, doesn't weigh anything, doesn't react chemically, and overall can't be measured, as if it doesn't really exist. But if it envelops anything it will shrink rapidly and the thing enveloped disappears from inside it. It also can make things come out of it, usually as an attempt to breach containment.
Additional Context: It stole dozens of SCP objects and personnel over the years. It repeatedly tried to breach containment by producing bombs, paranormal objects, and enemy agents from inside itself. A group was intercepted trying to recover it.
It's owned and operated by the Chaos Insurgency, but the Foundation doesn't know that yet.
