Bull Demon King

He is a demon king originally-based in the "Palm leaf Cave/Grotto" (棕櫚葉洞; Zōnglǘyèdòng), up on "Jade Cloud Mountain" (玉雲山' Yùyúnshān), with his wife, before betraying his wife for a younger demoness, Princess Jade-Countenance, a female Huli jing, of the "Sky-Scraping Cave" (摩雲洞; Móyún-dòng) on "Accumulated-Thunder Mountain" (積雷山; Jīléi-shān/积雷山; Jīléi-shān).

He is one of the most popular Journey to the West villains, alongside his wife Princess Iron Fan, his son the Red Boy, the Six-Eared Macaque, and the Baigujing.

"72 Terrestrial Killers"), he attaches one of his flaming wheels to the Bull Demon King's horns--horrifically burning him and causing him great pain--whilst Devaraja Li uses an "imp-reflecting mirror" (照妖镜; Zhàoyāojìng) to prevent the Bull Demon King from shapeshifting and escaping.

Princess Jade-Countenance would then later--2-years prior to her appearance in Journey to the West--after having learned of King Powerful's (the Bull Demon King's) reputation for enormous magic powers, used her equally-enormous inheritance as a dowry to lure him away from his first wife, Princess Iron Fan/Rākṣasī, becoming his second wife/concubine and he (to her mind) her consort over her late father's domain.

Her fate is later revealed by Zhu Bajie who killed her--after Sun Wukong first gave chase after the fleeing Bull Demon King--with one swing of his rake, before burning-out the Sky-Scraping Cave/Grotto.

The statues of the Bull Demon King and Princess Iron Fan have been established at the Flaming Mountains Scenic Area in Xinjiang and have become a popular tourist destination.
