Meng Huo is the king of the Nanman tribe and is highly protective of both his people and his wife. He seeks to defend them from threats and live in harmony. This occurs in various orders and locations throughout each game, but usually culminates in a final face-off with Zhuge Liang. In Shu's version of his home stage, he resists the Prime Minister seven times before he formerly surrenders.
Meng Huo is portrayed as a sweet but short tempered man who frustratedly attempts to outwit Zhuge Liang at every turn, but fails dismally each time. He has a very strong relationship with his troops and officers, and all consider themselves a close family with an unbreakable spirit. Although Meng Huo is the "Great King" and technically the leader of the Nan Zhong people, he is shown to be completely submissive to his wife, Zhu Rong, who is far more intelligent and aggressive than Meng Huo. He is depicted as being slightly short-witted, but very loyal, and is a modest and kind ruler. He is a fun-loving but sincere man who loves his wife dearly.
