SCP-203, Tortured Iron Soul

Prevent all combat damage dealt to SCP, 203.
At one time have been a Caucasian human male of indeterminate age, now the subject’s entire skeletal structure has been removed and replaced with a mechanical framework made of cast iron that seems
to move on its own volition. This framework appears to
be the sole cause of SCP-203’s ambulation,
independent of its musculature. Several areas of skin
on the subject’s body have split, revealing a
section of the subcutaneous metal framework.
