Mushu is the deuteragonist of Disney's Mulan. He was the small red dragon to help Mulan. At first, Mulan's companions were to be 2 reptilian creatures; the idea of the creatures being dragons had not been established. However, feeling that two sidekicks would overcrowd the story, the animators then decided on a two-headed dragon, though they were green and grotesque. After the animators decided on a single-headed dragon, they established Mushu's physical concept. For better use, the animators shrunk Mushu to a smaller size.

He is voiced by Eddie Murphy, who later voiced Donkey in the Shrek films and Mark Moseley in the sequel and later appearances.
