During the development of the original Star Fox, character designer Takaya Imamura originally wanted to make the characters generic humans and aliens, similar to his character designs from F-Zero. It was Shigeru Miyamoto who convinced him to instead make them anthropomorphic animals, as he wanted the game's aesthetic to stand out from every other science fiction property coming out at the time.

Fox in particular being a fox was inspired by the Fushimi Inari-taisha shrine located near Nintendo's offices.
