He was a legendary ruler of the Oni of Japan, and makes a good model for a very powerful Oni lord for Rokugan or other Japanese themed 5e fantasy. He was 50 feet in height, had a red body and a five-horned head, with fifteen eyes; one leg was white and the other black, while his arms were yellow and blue. He was, according to the myth, gotten drunk on rare sake, restrained, and beheaded, but still managed to bite his attacker, who only survived due to wearing multiple helmets.
