Shan-Yu (voiced by the late Miguel Ferrer) is the leader of the Hun army and the primary antagonist in Jaden meets Mulan. Shan-Yu and his army planned to conquer all of China. Jaden and Mulan managed to create an avalanche that buried most of his army (though Shan-Yu himself survived, along with a few elite Huns). When Shan-Yu attacked Mulan, Jaden helped her defeat him by using a giant rocket.
