In many fanfictions, Fem Naruto might show kindness towards the Kyuubi. This kindness could be something the Kyuubi has never experienced before. For example, instead of just seeing it as a source of power, Fem Naruto might try to understand the Kyuubi's past and pain. This could lead to the Kyuubi gradually opening up to her and them developing a deeper bond.
It could be an original character created by the fanfiction author. This character might be a descendant of the original Kyuubi, but with a female form and her own distinct personality.
In this fanfiction, perhaps Naruto meets the fem Kyuubi in a different dimension. The fem Kyuubi might be a more gentle and intelligent version compared to the traditional Kyuubi. She could teach Naruto some ancient ninja techniques that were lost long ago. They might also form an alliance to fight against a new common enemy that is threatening the Hidden Leaf Village.
In this fanfiction, perhaps Naruto discovers a new side of the female Kyuubi. She could have a more gentle and caring nature beneath her powerful exterior. Naruto, being the kind - hearted person he is, helps her to adapt to the human world. They could start a journey to find a way to coexist peacefully, not just for themselves but for the whole ninja world that has long feared the Kyuubi's power.
The idea of Naruto and a female Kyuubi in fanfiction has a lot of potential. It can give a fresh take on the Naruto story. For example, in some fanfictions, the female Kyuubi might have a different backstory compared to the original Kyuubi. This can lead to new emotional arcs for Naruto as he gets to know her. Their relationship could start off as rocky, with Naruto being a bit wary of her, but as time goes on, they could grow to trust and rely on each other, creating a heartwarming story.
Their relationship could start with mutual understanding. Naruto, who has always had a connection to the Kyuubi, now with a female form, could start to see her as more than just the beast inside him. They could have conversations about his dreams and her past.
It could be an evil ninja who wants to capture the fem Kyuubi for her power. He might see the unique bond between Naruto and the fem Kyuubi as a threat to his plans of world domination.
In some fanfictions, a possible plot is that Fem Naruto uses her femininity to her advantage when dealing with the Kyuubi. She could charm or trick the Kyuubi in some way that Naruto in the original couldn't. Like, she might offer the Kyuubi something it really wants in exchange for its power, but in a more cunning way.
At first, Naruto might be a bit scared or hesitant. But as the female Kyuubi shows her care and concern for him, he would start to trust her. They would gradually develop a mother - son type of relationship. The female Kyuubi could be strict at times to make Naruto a better shinobi, but also very loving.
In the fanfiction, the female Kyuubi could be a key factor in Naruto's growth as a ninja. She might challenge him to become stronger, not just physically but also mentally. For example, she could set up difficult tasks for him to complete, which would help him to master new skills. Their friendship would be based on mutual respect and the desire to see each other grow.
