Mushu is a red dragon, and the deuteragonist and comic relief of both Disney's 1998 feature film Mulan and its sequel. He is the titular character's closest companion throughout the Mulan series, acting as Mulan's guardian and protector.
He was voiced by Eddie Murphy in his first appearance and currently by Mark Moseley.
Mushu was once a guardian spirit of Mulan's family, but he had been demoted to the humiliating position of an incense burner and gong-ringer for the deceased Fa ancestors ever since he failed to protect a family member, a soldier named Fa Deng, resulting in the soldier's demise by decapitation (he's seen carrying his own head as a spirit).
In contrast to Mulan, Mushu is in most situations more comical, overconfident, funny and impulsive. He strives to be one of the family guardians again and selfishly decides to convince Mulan to join the army to turn her into a war hero, believing this will get him back on the "top shelf." However, he comes to realize how selfish he has been, admitting to Mulan that he risked her life to further his own goals. He then intends to take her home to face the consequences of his actions, but when she insists on stopping the Huns, Mushu loyally follows her, showing that underneath, he has a good heart. Mushu is rather sensitive about his size.
He's also always paired with Cri-Kee, a supposedly lucky cricket originally belonging to Grandmother Fa. He serves as Mushu's polar opposite and sidekick. Together, the two are often at odds, with Cri-Kee, unlike Mushu, being incredibly selfless and cautious, whilst Mushu is often self-centered and impulsive. Even so, despite usually bickering whenever they're together, the two are apparently best friends deep down, and do appreciate each other, as well as save one another on various occasions, especially on Mushu's end, as Cri-Kee is usually too small to take care of himself.
