Already designed my SCP, but am here looking for second opinions.
SCP is a humanoid entity, a former Foundation Security guard in full uniform, that has been afflicted by a black, oily substance coating his body. Because of this, he has been altered at the molecular level. The SCP lacks a skeleton and all vital organs, and despite retaining the man's identity, memories, and voice, it seems to be now entirely made of this substance. It has been able to liquify into the viscous substance before reverting back to a humanoid form and when losing sections of its body, has been able to regenerate severed limbs and missing sections.
SCP is kept contained in an airtight sealed containment unit kept at a minimum constant temperature of -100 degrees Celsius. SCP is completely frozen at this temperature, rendering containment breach impossible. SCP is only allowed to thaw for interview purposes.
What do you think?
