##He has no other name.

From his [biography][1],

> Shan Yu is the main villain from the Disney animated movie "Mulan". He is the leader of the Huns.

> He appears in "Kingdom Hearts II". There, he tries to use the Heartless to take over China, but Mulan, Sora, Goofy and Donald defeat him.

There are many other characters without a specific name in [Mulan][2], such as [The Emperor][3] and [The Matchmaker][4]. Maybe Disney didn't think the eastern names were that easy to memorize by western audiences?

Anyway, if Shan Yu is meant to represent the leader of the Huns, Disney might have been referencing [Attila, the Hun][5] (who in fact [invaded Europe, not China][6]), or some undisclosed leader of the [Xiongnu][7] (the [alleged predecessors of the Huns who did invade China][8]). Another source of inspiration, according to [this][9], is [Genghis Khan][10], leader of the Mongol armies (who also [invaded China][11]).

## His falcon is known as [Hayabusa][12].

> Hayabusa is Shan Yu's pet falcon and sidekick. The bird often acts as a warning signal, alerting China's victims that Shan Yu is near. He appears to be similar to his master: strict, ruthless and vicious. He latches onto his prey or whatever he needs to carry with his steely talons (as he did with Shan Yu's sword when Shang handed it to the Emperor).
