Fox is a fast-rising name for boys, initially popularized by the character Fox Mulder on The X Files, and recently resurged by the TV show's revival.

It was reported that the TV character's first name was not a tribute to the Fox network which aired The X-Files, as often assumed; show creator Chris Carter said he had a childhood friend named Fox.

On a little girl, Fox would be a tailored and fiery choice.

Fox is one animal name backed by a longish tradition, and then popularized via the lead character Fox Mulder on X Files. Fox is simple, sleek, and a little bit wild, and could make an interesting middle name.
