In many fanfictions, the Fem Bijuus act as catalysts for Naruto's growth. They may introduce new challenges that require Naruto to develop new skills or strategies. For instance, if a Fem Bijuus has a unique power, Naruto might have to learn how to work with or against that power, which in turn helps him become a more versatile ninja. Also, their presence can make Naruto more aware of the importance of relationships, as he may form different kinds of bonds with the Fem Bijuus compared to his male friends.
