Mortem Ossa aka "Morty" is a grave digger classification of demon.

Grave diggers raid graves for bones either to expand their collection, for use in curse, or to feast upon. Those who feed on bones are able to repair their bodies should physical harm come upon them if they ingest the bones. Grave diggers travel alone from other Grave diggers but greed demons are often seen following Grave Diggers in hopes of plundering gold and items of value from the Diggers ventures in burial sites.

Mortem Ossa feeds on bones, thus he is able to heal his physical body if harm is done to him. He is often seem with a greed demon known as Grinning Dog, who follows Morty in search of gold, jewels, and valuables.

I hope to turn this into a scare/Halloween suit eventually.
