Olsat was a minor demon from the original Devilman manga.


Olsat was a demon that seemed to be either be reptilian or amphibious based while resembling a kappa. He had a large blunt beak, with flat omnivorous teeth, deeply sunken eyes and a large crest atop his head. Placed in the center of the crest was a small crocodile like head. He had long wavy hair aside his head.


Olsat is one of the many demons seen in the visions of Akira Fudo after he had donned the Demon Mask. It was seen among a large crowd of demons, smiling malevolently near the back.
