Gyumao

Gyumao is based on Niúmówáng ("Ox-Demon-King", "Ox Devil Lord" or "Ox Tyrant") a character from the Chinese novel Journey to the West.

Despite his threatening name, he is really quite harmless and fun-loving; given that gyū is the crest on his helmet, it is incorrectly assumed by fans that Gyū is his surname and Maō is his first. He was somewhat demonic and frightening when his castle became engulfed in flames on Frypan Mountain.
