Hayabusa is Shan-Yu's pet saker falcon, who acts as his master's eyes and ears from the distance. At the end of the first film, his feathers are burned down by a fireball from Mushu, who then taunts him as "Mongolian barbeque". Doing so tames him and he gives Mushu and Cri-kee a ride, but isn't seen afterwards.
In Kingdom Hearts 2, Hayabusa appears in the boss battle against Shan Yu. He can grab Sora, lift him into the air, and throw him.
