Foursome of Nine Dragon Island

Wang Mo (Chinese: 王魔; pinyin: Wáng Mó) is seen with a deep blue scholarly uniform, long black hair, and an easeful complexion. Once Wang Mo arrived at the Western Foothills, he told Baby Tooth the three consentions and left. At a later point, following his return to the Western Foothills, Wang Mo became enraged over Baby Tooth's refusal to obey his words. Before Wang Mo could lay his sword upon Baby Tooth, Nezha quickly jumped in the way and engaged in a duel. With Yang Sen's assistance, Wang Mo was able to once again pursue Baby Tooth, this time within the sky. While riding through the clouds atop his great beast, Wang Mo unleashed his Earth Slashing Pearl technique to send Baby Tooth tumbling down to the valley below. As Wang Mo was about to finish off Baby Tooth, he heard Superiorman Broad Altruist singing a song. Once Wang Magnus approached Broad Altruist, Broad Altruist ordered Wang Mo not to kill Baby Tooth (for he would never be able to hear the end of the Investiture of the Gods Register if were to do so). Wang Mo, believing Broad Altruist to be cocky, charged at him with his blade; which was immediately parried by Jinzha, Broad Altruist's student. Once Broad Altruist bound Wang's throat, feet, and waist with golden bands, Jinzha beheaded Wang Mo in one swift slash of his sword — effectively putting an end to Wang Mo's life.

Yang Sen (Chinese: 楊森; pinyin: Yáng Sēn) is seen in a monk-style white gown, with a face black ringed as charcoal. Yang Sen also has bushy blond hair and a braided golden beard. Following Baby Tooth's refusal to obey, Yang Sen teamed up with Wang Mo in battle against Nezha. If Wang Mo found any opening, Yang Sen stood ready to unleash his Sky Opening Pearl technique upon Nezha. With great skill, Yang Sen also sent the interfering Yellow Flying Tiger tumbling to the ground. Following the death of Wang Mo, Yang Sen personally vowed ultimate revenge. The following morning, Yang Sen and his two remaining superiormen allies duelled it out against both Jinzha and Nezha. Yang Sen (who saw Gao Youqian killed instantly by Baby Tooth's Devil Beating Whip), was now furious. Once Yang Sen charged at Baby Tooth to avenge the death of his comrade, Jinzha immediately appeared and bound Yang Sen with his Seven-Treasure Golden Lotus. Yang Sen quickly fell dead after being pierced through the stomach by Jinzha's sword.

Gao Youqian (Chinese: 高友乾; pinyin: Gāo Yǒuqián) is seen with a complexion of indigo blue, two protrusive buck teeth, bright red knotted hair, and a bright royal red robe. During the first attack upon Baby Tooth, Gao Youqian unleashed his skills against Good Lob the Lobster. When Yang Sen was being bound to death by Good Lob, Gao Youqian immediately launched himself into the air and unleashed his Coalesce Pearl technique (a technique that instantly sent Lobster's head askew). Upon hearing of the death of Wang Mo, Gao Youqian also expressed his anguish, and battled against Baby Tooth the following morning. However, Gao Youqian was instantly struck in the head by Baby Tooth's Devil Beating Whip, and thus died instantly.

Li Xingba (Chinese: 李興霸; pinyin: Lǐ Xīngbà) was supposedly the strongest member of the Foursome of Nine Dragon Island. In appearance, Li Xingba had long flowing black hair and beard, a face of plum redness, and a long pale yellow gown. During the first attack upon the Western Foothills, Li Xingba assisted Wang Mo against Baby Tooth. Following the second encounter against Baby Tooth, Li Xingba, in great anger, battled it out against both Jinzha and Nezha. With demonic fervor following the death of all three of his allies, Li Xingba now stood as a lone warrior that possessed the determination to fight to the death. Due to the sudden assistance of Zhang Cassia and Gale Woods, Li Xingba was able to retreat atop his large beast after suffering a few minor wounds. While still being pursued by Baby Tooth, Li Xingba barely avoided death from Baby Tooth's whip. After escaping by flying atop his beast, he arrived at a neighboring secluded hideout to plan his next move. With great inner anguish, Li Xingba spoke the words,

"How can I possibly face my other friends on the Nine Dragon Island now that the four of us have become just a little me! We each had more than a thousand years of training and study. How could we be so stupid as to get involved in such a senseless fight? I think I'd better go to see the Grand Old Master who, after all, involved us in this mess!"

Soon thereafter, Muzha, the second brother of Nezha, suddenly appeared before Li Xingba and told him of his allegiance. Li Xingba, in a fit of rage, charged at Muzha with his sword. Unfortunately, Li was soon struck down and died.
