In a 'Naruto adopted by Kyuubi' fanfiction, the plot could be really interesting. Since Naruto is adopted by the Kyuubi, he would be exposed to a whole new world of power and knowledge. The Kyuubi could teach Naruto how to harness his own chakra more effectively, as it is the source of Naruto's power. Naruto might also learn about the ancient secrets that the Kyuubi has been keeping for centuries. This could lead to him developing new jutsu that are a combination of his own Uzumaki heritage and the Kyuubi's power. He could then use these abilities to protect the village in a way that no one else could, and also change the relationship between humans and tailed beasts for the better.
One possible plot could be that Naruto, instead of being shunned in the village, is secretly taken in by the Kyuubi. The Kyuubi, seeing Naruto's loneliness, decides to raise him. Naruto would grow up learning unique skills from the Kyuubi, like advanced chakra control and perhaps some secret fox - related jutsu. This would make him a very different kind of ninja compared to the original Naruto in the series.
If Naruto was adopted by Kyuubi in fanfiction, it could lead to a completely different Naruto. He might be more confident earlier on. Since Kyuubi is a very powerful being, Naruto could be trained in unique ways. For example, he could learn how to harness Kyuubi's power more effectively without the need for the traditional methods of suppressing and drawing on the fox's chakra. This would change his relationships with his peers too. He might be seen as an oddity, but also as someone with great potential.
Well, one possibility could be a very creative and out - of - the - box plot where Naruto's unique bond with the Kyuubi leads to some sort of magical or spiritual connection that results in an unexpected pregnancy. But this is a very strange and far - fetched concept in the Naruto universe as it goes against the normal biological and story elements.
The plot of a 'naruto frees kyuubi fanfiction' might involve an external threat to the village. This threat is so great that Naruto realizes he needs the full power of the Kyuubi, not just the limited access he has through the seal. So, he starts to work on breaking the seal. Along the way, he has to face opposition from some in the village who fear the unleashed Kyuubi. But Naruto is determined. He finally frees the Kyuubi and together they defeat the external threat. After that, the Kyuubi decides to stay with Naruto as a friend and ally, seeing the true nature of the young ninja.
Well, perhaps in this fanfiction, the idea is that Naruto and the Kyuubi have a spiritual mating of sorts. It might mean that Naruto gains an even deeper understanding of the Kyuubi's nature. This could involve Naruto delving into the Kyuubi's memories and learning ancient secrets that help him not only in combat but also in his journey to bring peace to the ninja world. As a result, they become an even more formidable force combined.
In a 'naruto adopted by hiruzen fanfiction', the plot could involve Naruto having a closer bond with the older generation of shinobi. Hiruzen would surely introduce Naruto to his trusted comrades. Naruto could learn unique jutsu from them. Also, his growth as a ninja would be different. Instead of seeking attention through pranks, he might focus more on living up to Hiruzen's name. His relationship with Sasuke could also be affected. Maybe they would become rivals in a more positive way, with Naruto having a stronger sense of family and purpose because of Hiruzen's influence.
Well, perhaps in this 'naruto adopted by grayfia fanfiction', Naruto's own world is in chaos and he gets lost in a portal that leads him to Grayfia's realm. Grayfia sees Naruto's potential and loneliness. She adopts him and starts to train him in the ways of her world. Naruto could struggle at first, but his determination from his ninja training helps him. He might get involved in local disputes or power struggles in Grayfia's world and use his unique abilities to make a difference.
If Naruto was adopted by Tsunade in fanfiction, he would probably be exposed to a different set of values. Tsunade is a strong - willed and sometimes reckless woman. Naruto could pick up on her fearless attitude towards battle and also her more practical approach to leadership. Also, their relationship might change the power dynamics in the village a bit, as Naruto would be directly under Tsunade's wing.
Well, one possible plot could be that Naruto, being adopted by Yugito, would learn a lot about the Nibi (Two - Tails) from her.

Naruto might also gain a new family - like bond with Yugito, which could help him deal with his own feelings of loneliness from his past.
Well, one possible plot could be that Naruto is somehow transported to the Star Wars universe. The Jedi sense his strong force potential within him, which is similar to his chakra in his own world. They decide to adopt him and train him in the ways of the Jedi. He might struggle at first with the different concepts and rules, but his determination from his ninja training helps him adapt quickly.
The plot could involve the Mizukage adopting Naruto as a way to protect him from certain threats in Konoha. Naruto then grows up in the Hidden Mist village, making new friends and rivals. He could also have an influence on the village's view of Jinchuriki. Since he is a Jinchuriki himself, he might be able to change the negative perception that the Hidden Mist has towards those with tailed beasts inside them, and together they could work towards a more positive future for Jinchuriki in general.
