Background / History
Yu Xiaogang is a direct-line descendant of the Blue Lightning Tyrant Dragon Clan and the grandson of its current clan head, Yu Yuanzhen. His external martial soul, Luo Sanpao, became a defining part of both his identity and his research into martial souls. 4 29
In his younger years, he formed the Golden Iron Triangle with Flender and Liu Erlong: Flender was the Flying Corner, Yu Xiaogang the Wisdom Corner, and Liu Erlong the Slaughter Corner. Both men loved Liu Erlong, but she chose Yu Xiaogang. Their relationship ended after they discovered they were cousins, after which Yu Xiaogang fled rather than confront the situation. 36
Yu Xiaogang was personally granted the title “Grandmaster” by the Pope of Spirit Hall for his martial-soul theory, particularly the Ten Core Spirit Competencies. Bibi Dong regarded him as her lost love, and her attachment to him affected how she viewed Qian Ren Shuang. 21 22
After arriving at Shrek Academy, Yu Xiaogang sought to study Qian Ren Shuang and Guilmon as a research subject. Qian Ren Shuang rejected him violently, kicking him from his room after being awakened. 21 22 Yu Xiaogang later became one of Shrek's newly introduced teachers and organized practical training for Tang San's group. 22
Personality
Yu Xiaogang is highly proud of his scholarly reputation and frequently presents himself through his titles, theory, and connection to the Blue Lightning Tyrant Dragon Clan. He considers the Ten Core Spirit Competencies his defining achievement and reacts stubbornly when its principles are challenged. 21 29 30
Despite his authoritative manner, he is fearful in direct danger. He hides behind Flender during the battle between Liu Erlong and WarGrowlmon, fears confronting Liu Erlong because of their past, and submits to Qian Ren Shuang's demands when physically overpowered. 30 36 40
He remains devoted to Tang San as a teacher, arranging training, defending Tang San's potential, and accepting Tang Hao's instruction to keep Qian Ren Shuang close for Tang San's future benefit. 22 45
