Emperor Bairong is the ruler of the Biarong Empire and the father of Yue Bairong, Lee Bairong and Xing Bairong.
Emperor Bairong is eager to expand the Bairong Empire, as shown when he tells Yue that he and the 50 former emperors all wanted to recreate the Bairong Empire. When Lee attempts to assassinate Yue, Emperor Bairong appears and defeats them, and is about to kill Lee when Yue stops him.
It is shown that he is aware of the switch between Yue and Xing, and threatens to bring the real Yue back and torture them both.
After a long deduction made by Lee, it is revealed that Emperor Bairong had taken over Yue Bairong's body. He is shown favoring Lee, stating that he should have made Lee his heir, and that the White Dragon's choice was regretful.
