Li Shang
Li Shang is the captain of the Chinese army sent out to defeat Shan Yu as well as the love interest of Fa Mulan.
He doesn't appear in the first two games, but makes an appearance in the third game as captain of the Chinese army to protect the Land of Dragons from falling into the hands of Shan Yu.
He initially despised Ping (who is Mulan in disguise) because of "his" incapability of fighting, but learned to trust "him" after "he" causes a mountain of snow to fall down on Shan Yu and his army. However, Mushu accidentally spills the truth out of his mouth and Shang realizes that Ping is actually Fa Mulan. She was supposed to be sentenced for death, but he spared her life.
When Shan Yu is found out to be alive and heading for the Imperial City, Mulan tries to warn him, but he refuses to listen until he sees it himself. He then rescues the Emperor and thanks Mulan, Sora, Donald and Goofy for their help of protecting their country.
Upon Sora's second visit, a black hooded man (who is actually Riku) visited the Emperor and easily defeated the Captain. After Mulan, Sora, Donald and Goofy defeat the Storm Rider Heartless, Mulan becomes Shang's partner in protecting their world and the Emperor, much to their pleasure.
