Hua Mulan is a legend of China. She took her father's place in the army, for twelve years. After the war, she refused any rewards and retired in her hometown.
While the merciless Shan-Yu leads invading Huns over the Great Wall, young Fa Mulan sees a matchmaker about her matrimonial future. Mulan's views on accepted marriage traditions prompt the ballad, "Reflection," as she hopes for recognition of her true self. To repel the Huns, a man from each family is required to join the Imperial Army. When Mulan's elderly father Fa Zhou volunteers, she objects. He warns, "I know my place. It is time you learned yours." Mulan, however, cuts her hair, dresses as a man, and is ready for military camp so her father can rest at home without entering war, prompting the concern of her First Ancestor, who converts an inanimate incense burner into the 18-inch high comedic dragon Mushu. With Mushu hidden in her clothing, she joins a group of raw recruits under the command of Captain Shang. During an ambush by the Huns in a mountain pass, Mulan steps in to turn defeat into a victory.
Mulan's first appearance was in Kingdom hearts 2, she helps Sora, Donald and goofy fight Shan Yu leader of the Huns to save the Land Of the Dragons. In their second meeting Mulan helps Sora take down a gigantic dragon. Sora can use Mushu as a summon in this game after the Mulan levels are beaten.
