Don’t look down on the Dragon King-sama, fox lady! I am very amazing!

–Yu-Long to the brainwashed Yasaka, Volume 9, Life.4 Showdown, Gremory Group VS Hero Faction! In Kyoto.


Yu-Long is one of the Five Great Dragon Kings, he is known as the Mischievous Dragon[1], or the Jade Dragon. He is the partner of Sun Wukong. Like Sun Wukong, he is also a character featured in the Chinese novel Journey to the West.


Yu-Long has the appearance of a large green Asian Dragon.[2] It had red eyes, and a lime, scaly underbelly, while the rest of it was shrouded in jade. Near its arms, where his body laid, were bronze curving shards.


A lazy but enthusiastic Dragon, self proclaiming himself as "The Liveliest Dragon" and is shown to love good food.[2] Unlike his fellow Dragon Kings, Yu-Long displayed a cowardly side as he runs away from opponents more powerful than him like Fenrir and Gogmagog, and later begging Sun Wukong to finish his fight to help him against his opponents.


Yu-Long is a Dragon King that transformed into Monk Xuanzang's horse after eating his horse and helped in Xuanzang's travels. He then went missing along with Sun Wukong after the two of them completed their task of accompanying Xuanzang to retrieve Buddhist sutras from India.
