Well, it could be about Naruto as a sennin and his connection with the Kyuubi. Todd might be a new character introduced into the Naruto universe. Maybe Todd has some special ability that can either help or hinder Naruto's control over the Kyuubi. For example, Todd could be from a far - off land where they have different ways of dealing with powerful entities like the Kyuubi, and he tries to share his knowledge with Naruto to make him a stronger sennin.
Perhaps Todd is a normal villager who has always been fascinated by Naruto. One day, he discovers that he has some latent ability that is related to the Kyuubi's power. Naruto, as a sennin, takes notice of Todd and decides to train him. So, Todd could be an underdog character who is thrust into the world of ninjas and the Kyuubi's mystery.
In a fanfiction scenario where Naruto has Rikudou Sennin's powers, Kyuubi's chakra, and the Rinnegan, his power level would skyrocket. The Rikudou Sennin powers would enhance his understanding of chakra and life itself. The Kyuubi's chakra would boost his physical and chakra - based abilities even more. And the Rinnegan? That would open up a world of new jutsu possibilities. He could potentially reshape the Naruto world as we know it, perhaps even finding new ways to bring peace between the villages.
One interesting plot could be that Rikudou Sennin is reborn into a time when the ninja world is on the verge of a new, unknown threat. He has to quickly regain his powers and knowledge to guide the new generation of ninjas, like Naruto and his friends, to face this threat. Maybe he has lost some of his memories in the rebirth process, adding an element of mystery and self - discovery to the story.
One interesting plot could be that Rikudo Sennin from the Naruto universe gets accidentally transported to another dimension where he meets characters from a different story. He then has to use his powerful jutsu and wisdom to find a way back home while also getting involved in the affairs of that new world, like helping the local heroes fight against a powerful villain.
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.
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.
One possible fanfic could be about a young ninja who discovers he has a connection to both the Rikudou Sennin and the power of the Kyuubi. He then begins to develop the Rinnegan in a journey of self - discovery. This could involve him facing off against powerful foes who are also interested in these powers.
One possible plot could be that Rikudou Sennin somehow gets transported to the world of Highschool DxD. Maybe his powers disrupt the balance there. For example, his chakra could be mistaken for some kind of new and strange power in the DxD world. The characters in DxD might initially be wary of him but then start to see the potential of his abilities and try to recruit him for their own purposes.
