Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX-1 is allowed level 3 security clearance and can walk around the facility, but a D class personnel is to follow it around anytime it is not in its container. The D class personnel will monitor it and make sure it is contained in case of emergence of SCP-XXXX-2. If SCP-XXXX-2 emerges or is about to emerge, it should be contained in its box, a large metal briefcase that has a clear window for study of SCP-XXXX while contained. The box locks to form an air tight seal to prevent escape of SCP-XXXX-2.
If SCP-XXXX-2 isn't contained, the area it is in (even ventilation) will be locked so no air can get in or get out. A team of agents required to wear gas masks will be dispatched to keep SCP-XXXX-2 in the area it is in and try to force it into containment.
Description: SCP-XXXX in its dormant form is a rough, jagged, crystalline object about six inches long that is black in color. The crystal as far as current research shows, cannot be damaged by any physical means and has an unusual wight for an object of its size, weighing in at 11 kg. The crystal object has the ability to project two different physical forms, SCP-XXXX-1 and SCP-XXXX-2.
SCP-XXXX-1 starts out as black smoke projected around the crystal, but it congeals into a humanoid shape if left out in a large enough space. The humanoid shape solidifies after half a minute but continues to emanate black smoke. The humanoid is wearing a common SCP scientist's uniform and lab coat, they have light brown hair and slight stubble. SCP-XXXX-1 is the form of SCP scientist Dr. Matt Edwards, recently thought to be dead in a lab incident.
The appearance of SCP-XXXX-2 is implied by the SCP-XXXX crystal turning red, after a minute or two projected by the crystal is SCP-XXXX-2, a blood red, swirling, cloud-like mass that moves in shaky movements. SCP-XXXX-2 as far as can be discerned, is hostile to all living creatures meaning it attacks anything that comes near it. While SCP-XXXX-2's body is a gaseous cloud, it had been observed to form spikes/ blades to attack things it sees, though it doesn't seem to be able to attack materials like steel or concrete. SCP-XXXX-2 seems to prioritize escape over attack, it will attempt to escape and only attacks those who get in its way.
