The exploration of their abilities in new ways. Fem Naruto might have different ways of using her powers compared to male Naruto. When paired with Killer B, they can come up with innovative combat strategies.

Well, in such a fanfiction, there could be various hints. Maybe Zoro's behavior might be more in line with typical female characteristics described in that specific fictional world, like being more empathetic or having different social interactions compared to the original male - character version.
