Mushu

Mushu is a dragon and one of the main protagonists from Disney's 1998 hit Mulan and its sequel. He is the titular character's closest companion throughout the Mulan series, acting as Mulan's guardian and protector. He is voiced by Eddie Murphy in his first appearance and Mark Moseley afterwards.

Development
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. Around the time when the music of the film was to be created, the songwriters had written a piece for Mushu for him to sing to assure Mulan that he'll be there to help her. However, after Eddie Murphy came to voice the character, the character and his dynamic changed, and the animators canceled the piece, although it was a favorite among the filmmakers.
