In demonology, Vapula is a powerful Great Duke of Hell that commands thirty-six legions of demons. He teaches philosophy, mechanics and sciences.
He is described in the Ars Goetia as "a lion with griffin wings", and is usually in this manner how he's portrayed.
Vapula is depicted as a lion with feathered wings and purple fur. It has a long, thick mane and red fur at the joints on the legs. Vapula closely resembles its original description. It has a similar attack pattern as Glasya Labolas and attacks by spewing two long lines of waving runes that cause Curse status on contact. This is perhaps based off its high level of knowledge, as described in the Ars Goetia.
