I don't think it's a very popular theme in the fan community. Naruto's story is mainly about his journey to become a great ninja, protect his village and his friends. The idea of Naruto impregnating Kaguya is so far - fetched from the original plot. Most fans are more interested in fanfictions that expand on the existing relationships in the show or explore different power - up scenarios for the characters. So, in short, this theme doesn't really resonate with the mainstream fanfiction trends.
One possible plot could be in an alternate universe where Naruto and Kaguya are brought together by some sort of magic or time - travel anomaly. Instead of a physical relationship in the traditional sense, it could be more of a spiritual connection that results in a new form of power being born within Naruto that is symbolically like an 'impregnation' of sorts. For example, he could gain some of Kaguya's unique abilities which then change the course of his battles and his journey to protect the ninja world.
Well, Naruto could change Kaguya in the fanfiction by introducing her to the concept of redemption. Given his own journey of facing his inner demons and coming out stronger, he might convince Kaguya that she can atone for her past sins. He may take her on a journey through the ninja world, showing her how people have rebuilt and thrived despite the chaos she once caused. This could make her re - evaluate her actions and change her perspective on the world and her place in it.
Yes, there are likely some fanfictions that explore a special connection between Naruto and Kaguya. In some fanfictions, authors might create scenarios where Naruto, due to his unique abilities and kind - hearted nature, manages to reach out to Kaguya in a way others couldn't. This could involve him understanding her past and trying to bring some form of redemption or peace to her.
In the fanfiction, Naruto could enter Kaguya's mind. He might discover her past traumas that led her to become so power - hungry and vengeful. By understanding her pain, Naruto could offer her forgiveness and a new path. He could show her a vision of a future where she is part of a united world, not feared or hated, but respected and loved if she changes her ways. This could be a powerful incentive for Kaguya to change.
One consequence could be that Naruto has a constant struggle to keep Kaguya's power in check. He might experience internal battles within his mind as Kaguya tries to break free.
Well, it depends on the specific fanfiction. There are countless fanfictions out there, and some might indeed have the concept of Naruto being Kaguya's transmigrant. This could lead to some really strange and fascinating storylines. For example, it could change Naruto's relationship with other characters, his powers might be affected in new ways, and it could even rewrite the entire Naruto - Shippuden arc with this new premise.
One great Naruto fanfiction about Kaguya could be one where Naruto has to face Kaguya again in a new dimension. He uses his unique bond with the tailed beasts and his own growth in ninjutsu to outwit her. In this story, Naruto discovers a hidden weakness of Kaguya that was not known before, leading to an epic battle and a new era of peace in the ninja world.
Yes, there are likely some fanfictions with this concept. Fanfiction writers often come up with unique and creative ideas, and the idea of Naruto having some sort of special connection or relationship with Kaguya Otsutsuki in a fan - created story is not unheard of. It could involve Naruto exploring Kaguya's past, or perhaps having a role in her redemption in the fanfic's alternate universe.
I really like 'Kaguya's Unseen Journey'. It delves deep into Kaguya's backstory before she became the main antagonist in Naruto. It gives a more in - depth understanding of her motives and her relationship with the other characters. There are also some really creative fanfictions that involve Kaguya teaming up with Naruto and the gang to fight a new threat.
