Miyu is a character from the formerly canceled game Star Fox 2.
She is a beautiful female human-like lynx with a tomboyish personality.
As with Fay, Miyu pilots a faster Arwing model type called the Interceptor, which lacks in hull armor compared to the other Arwing models. However, an upgrade found later in the game can make up for this loss of defense.
Given that so many elements of Star Fox 2 were carried over to Star Fox 64 (such as the Star Wolf team) it could be considered that Katt Monroe, an ally of Star Fox who was also a cat, may have been Miyu's replacement.
