The Unnamed Flesh demon was one of the many present at the Black Sabbath seen at the end of the animated film, Devilman: The Birth.
As the name suggests, the demon resembled an inside out human with their exposed flesh covering his body. He seemed to have webbed fingers, bulging yellow eyes and misshapen teeth.
The Flesh Demon was one of the many who was present at the birth of the Devilman.
He was seen in several group shots before he was eventually grabbed by Akira and thrown down onto Wagreb's spikes spearing the demons body in half.
