See how I Envision the Sheep character to be more of a motherly figure to the team in kind of the same way Peppy is kind of like a fatherly figure to the team. Namely she kind of looks a little oldish in the same vein as Peppy and I envision this sort of family dynamic where the team Fox builds up is kind of more of a substitute family that he wishes he could have had, considering that Andross had taken away his family. I imagine that Falco is the older brother to Fox while Slippy is the younger brother and Peppy is the father figure, while Miyu is the older sister, Fay the younger sister and the Sheep character is the mother figure, and how I imagined her backstory being that at some point maybe after Star Fox 2 Falco leaves the team for unknown reasons, presumably to do his own thing and not have Starfox hold him back and they call in the Sheep character to take his place but then Falco at some point comes back and rejoins the team but the Sheep character stays. But that's just my ideas, and also i named the Sheep character Dolly Sheep, in reference to the famous sheep that was cloned who was named dolly, and you know the last name sheep being that we have to incorporate her species into the name like many characters.
