One of the things I love about the FF series, is the variety of its females. You can have everything: the weak ones and the strong ones. The dependent ones and the independent ones. The fighters and the healers. The shy ones and the flirty ones.
Their roles may vary, too. We have love interests and comic reliefs. We have goddesses and villains. We have mothers and sisters and daughters.
The central female may be strong or weak, a princess of a peasant, joyful or worrisome.
I have been writing a huge FF crossover where the females meet and I know that each and every one have their own voices.
