he 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 framework1. In addition to these areas, some parts of the metal structure seem have been made to intentionally protrude from the flesh.
