Fay is a human-like female cocker spaniel who along with Miyu, was to appear in the cancelled Star Fox 2 title for the Super Nintendo Entertainment System. As with Miyu, Fay pilots an Interceptor class Arwing which is far faster than the other Arwing models, but wasn't built with defense in mind. Her personality seems especially cheery and the "go-getter" type. She is characterized by her bubbly attitude, white fur, and a big red bow in her hair. No official artwork of Fay was ever released.
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 Bill Grey, an ally of Star Fox who was also a dog, may have been Fay's replacement.
