What are the Belu? Belu are Burmese rakshaka (Hindu term for ogres, think "orcs" since 4000 BC) who appear in humanoid form, but are capable of shape shifting. There are two types of belu: pan-kike belu, and panswe belu.
Pan-kike (flower biter) belu have straight fangs and are malevolent man-eaters.
Panswe belu, on the other hand, are benevolent beings that feast on flowers and fruit,
and are distinguished from pan-kike belu by curved or hooked fangs.
Nan Belu - palace ogre - (garuda bird) singular
Taw Belu - forest belu - Looks like a green ape ape with buck top teeth and curling upward tusks from the upper canines. The forest Belu are renowned for eating raw meat and wearing a large plume on top of their headdresses. In puppet shows, one always stands on the right of the stage and always enters and exits from the right.
Roundabout the end of August, a little-known spirit worship festival called Yadanagu which could be loosely translated as “Cave of Treasures” is held just outside of the town of Amarapura, near Mandalay on the way to the Irrawaddy Bridge. The festival is dedicated to a flower-eating belu ( ogre ) mother who supposedly died at Yadangu after hearing of the execution of her two sons and became a nat or spirit. Others say it is a festival started in the Ava period ( about 200 years ago ) to take the people’s attention away from politics and the scandals of the royal court of Ava, the ruins of which are not too far away from where this event is. Anyways, it is here that nat-kadaw (nat? wives / spirit mediums), nat-devotees and day visitors taking a break from the daily grind come to pay their respects to the belu mother with dancing and feasting with some shopping thrown in between.

Methinks he never made up orcs, ever. Was he inspired, mayhaps? Or since was it simple stealing and taking full credit?
