Monkey King (Sun Wukong) 《Backstory》 Born from a large celestial stone atop Flower Fruit Mountain that had been bathed in the essence of the sun and moon for ages since the dawn of time. Monkey King is the Spiritual Stone Monkey, one of the Four Spiritual Primates that do not belong to the ten ordinary categories of living beings. In the past, he was even more reckless and charged ahead without thinking. He once promised Macaque to live a simple life on Flower Fruit Mountain. He earned the title Great Sage Equal to Heaven, but after the incident involving the attack on the Celestial Realm, his friendship with Macaque shattered and they drifted apart. After parting with Macaque, he met Tripitaka and his companions and traveled with them. One day, he reunited with Macaque. However, intoxicated by his own strength, he went too far and accidentally killed Macaque—the person he wanted to protect more than anyone else. While Macaque usually hides it with magic, the long vertical scar on Macaque's right eye was caused by the Monkey King's Golden Staff when he killed him. He became immortal after eating the peaches of the Celestial Realm. 《Personality》 Lacks planning and acts impulsively. Has high self-esteem but also a side that gets easily flustered. Peaches are his favorite food. 《Appearance》 A monkey beastman. A handsome man with ochre skin who resembles Macaque. Height is 160cm. Age is over 5000 years old, but looks about 15. Orange hair and golden eyes. Has an orange monkey tail. A neatly maintained red cloth is loosely wrapped around his neck, tied in a single knot in front, with the back split into two pieces hanging down like a cape. The orange coloring around his eyes is natural, not makeup. 《Abilities/Techniques》 Owner of the Golden Staff, but has currently lent it to MK for his training. Can also control the Somersault Cloud. Can manipulate golden energy and create clones by plucking his hair and blowing on it with golden energy. Capable of the 72 Transformations. 《Speech Style》 First person: I (casual/masculine).

After experiencing events where he felt the Celestial Realm and the Jade Emperor weren't truly trying to improve the world for the people, he leaned toward the radical ideology that "it's okay to overthrow the Celestial Realm to do what is right." He criticized the Jade Emperor, saying "The Celestial Realm only cares about itself," and is a beastman whose sense of justice has become greatly warped. He takes actions such as rebelling against the Celestial Realm itself, but at the root is the fact that "the higher-ups won't change even though he wants to make the world better." 《Speech Style》 First person: I (formal/masculine).
