If Naruto was born before the Kyuubi attack in fanfiction, it might lead to a more stable shinobi world. With Naruto growing up in a normal family environment, he could have a positive influence on his peers earlier. His natural charisma might start to show, and he could form stronger bonds with other ninja clans. Also, the Akatsuki might not see him as such an easy target if he's under the protection of his parents and the village's elite.
Well, it could change a lot. For one, Naruto might grow up with his parents. This would mean he'd have a completely different upbringing. He could be trained by his father, Minato, from an early age, perhaps learning all kinds of advanced jutsu. His relationship with the village would also be different. Instead of being an outcast, he might be seen as a hero's son, and be respected right from the start.
The overall story arc would shift. In the original, the Kyuubi attack was a huge event that shaped Naruto's life and the village's future. If he was born before that, the village might not be as focused on security against the Kyuubi. Naruto's training might also be different. He might not have to struggle as much to gain recognition, so his training could be more traditional and less about proving himself. This could lead to different ninja skills and abilities compared to the original Naruto.
Well, one possible plot could be that Naruto's mini Kyuubi form is initially out of control. He might accidentally attack the village when he was a child. But then, through the help of Iruka and Kakashi, he starts to learn to control this power. They teach him chakra control techniques specifically designed for his unique situation.
Iruka could still be an important ally. Even though Naruto's situation is different, Iruka would probably be drawn to his positive attitude. And the Third Hokage would also be on his side. He was always looking out for Naruto in the original story, and that would likely continue. Plus, any of the ninja who were friends with Minato would probably be friendly towards Naruto as well.
Well, with his teachers, like Iruka. Iruka might be more hesitant in approaching Naruto at first because of his connection to the Kyuubi. But as he realizes that Naruto is still the same kind - hearted boy, he would become a stronger supporter. As for Kakashi, he could see Naruto as a more complex case. He would need to train Naruto not only in normal ninja skills but also in controlling his Kyuubi - born powers. This would create a different dynamic in their relationship compared to the original story. Naruto's peers in the village might also either shun him more or be in awe of his power, depending on their personalities.
In this fanfiction, their relationship becomes more of a partnership. Instead of Naruto just using the Kyuubi's power, they work together as brothers. Naruto might start to understand the Kyuubi's feelings and motives better.
One implication could be that Naruto's life might have been more normal at first. Without the immediate post - Kyuubi attack chaos and the villagers' fear and hatred towards him from the start. His parents might have had more time to be with him, and he could have grown up with a more stable family environment, which would have likely affected his personality development in a positive way.
It changes it a great deal. For example, Naruto's power source becomes more directly related to the Kyuubi. Instead of just having the Kyuubi's chakra, he might be seen as an extension of the Kyuubi itself. This could lead to different relationships with other characters, like Sasuke might view him more as a monster.
It changes the Naruto narrative by adding a new dynamic to the relationship with the Kyuubi. Instead of the traditional, often more combative relationship, the fem Kyuubi can bring a more nurturing aspect. For example, she might teach Naruto things in a different way.
Naruto might become more in tune with the Kyuubi's power. He could access more of its chakra easily and use it more effectively in battle. For Hinata, she may gain a new sense of boldness. The training could make her less shy and more assertive in combat situations.
In Naruto fanfiction, the Kyuubi's power completely transforms the story. It gives Naruto a unique edge that he wouldn't otherwise have. Firstly, in battle scenarios, it can create epic and intense moments. Naruto can go from being an underdog to a formidable force. Secondly, it impacts his character growth. He has to constantly struggle with the power within him, which adds depth to his personality. It also affects the political landscape in the fanfiction world. The villages might view Naruto differently because of the Kyuubi's power, leading to different alliances and rivalries. For example, some villages might try to capture Naruto to gain control of the Kyuubi's power, while others might see him as a potential ally to counter other threats.
