The outcome of the fight in the 'naruto fights the kyubi fanfiction' is quite uncertain. Naruto has his own set of skills, like his Rasengan and his ability to use shadow clones effectively. On the other hand, the Kyubi has raw power that is almost unrivaled. If Naruto is able to find a weakness in the Kyubi, perhaps something related to its past or its connection to the ninja world, he could win. But if the Kyubi manages to break Naruto's spirit, then the Kyubi would be the victor.
In this kind of fanfiction, Naruto might face a great challenge. He could use his new jutsu that he has learned over time to combat the Kyubi's powerful attacks. Maybe he'd have to tap into some hidden reserves of his chakra.
One great Naruto fanfic about him controlling Kyubi power is often centered around his growth as a ninja. It shows how he overcomes the initial struggle of harnessing such a powerful force within him. As he gradually gains more control, his abilities in combat and his standing in the ninja world improve significantly.
Another theme is acceptance. Naruto has to accept the female Kyuubi as she is, with her own personality and motives. And the female Kyuubi has to accept Naruto's way of life and his values. This mutual acceptance is often a key part of the story. For instance, in some fanfictions, the female Kyuubi initially doesn't understand Naruto's desire to protect the village, but gradually comes to accept it.

One possible plot twist could be that Naruto, while in his Kyubi form, loses control completely and starts to attack his friends. This would create a huge internal conflict for him when he comes back to his senses. Another could be that his transformation into the Kyubi gives him new abilities that are not related to just brute strength, like the power to communicate with other ancient beasts. Also, perhaps the transformation is not permanent, but rather fluctuates based on his emotions, leading to some really tense moments during battles or important interactions.
