Hua Xiong is Dong Zhuo's most trusted general. Unlike Lu Bu, Hua Xiong is only powerful and not smart. His strength is incredible, though. He discovers Huang Gai and the rest of the Sun soldiers in Luoyang, and he kills many of them. Huang Gai escapes, but the two are evenly matched. Later Hua Xiong ambushes Yuan Fang's group, but he was tricked; his army had to travel around the city walls, so the horses got tired. Dong Zhuo then appeared, and he revealed the strategy that Hua Xiong didn't know about. Because of this, it can be said that Hua Xiong is either not trusted enough, or is not smart. Either way, he follows Dong Zhuo with blind loyalty.
At Sishui Pass, Hua Xiong's army ambushes what is left of the warlord alliance. Hua Xiong successfully kills 13 generals in succession in duels. At the scene is Lu Bu and Zhang Liao, and they immediately plan to kill Hua Xiong. Hua Xiong loses against Guan Yu in a duel, and leaves with one arm chopped off. Lu Bu moves in to save Hua Xiong, and Hua Xiong can only regret his life. Then Zhang Liao kills Hua Xiong to further Lu Bu's plans.
Personally, Hua Xiong is a minor character, but he is talented. His only problem was that he was placed between the ambition of Lu Bu and Dong Zhuo. He didn't stay alive very long, so I cared little for him.
