Dragon King of the Western Ocean, Goujun is a character that appears in Saiyuki Gaiden manga.

Background Sole person responsible for Heaven’s Western Army, Tenpou and Kenren’s superior officer. He’s strict about discipline as an army officer should be, and undoubtedly takes heaven’s orders as absolute. He discards excess things and is very punctual. He values Tenpou highly, and from early on he rescued Goku and the others, who had begun to associate with Tenpou at some point, from danger. He got caught up in the fours’ rebellion, and even though he didn’t understand their thinking, he saw their paths with his own eyes. He has two horns growing from his silver hair. Scales dot his porcelain skin, and his eyes are red and gold. His strange appearance is closer to that of a youkai than a god. Source: Saiyuki.wikia
