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.
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.
It changes the Naruto universe by introducing a new dynamic. Usually, Kaguya was seen as an ultimate villain. But if she falls in love with Naruto, it turns the whole concept of good and evil on its head. It could lead to a more united ninja world as they have to accept Kaguya in a new light. Also, Naruto's influence on Kaguya might change how she uses her powers. Instead of being a source of destruction, her powers could be used for the betterment of the ninja world.
In many fanfictions, Naruto might defeat Kaguya by unlocking a new form or power. For example, he could master a more advanced version of Sage Mode or combine his Nine - Tails chakra in a completely new way. This new power could give him the edge needed to outmatch Kaguya's abilities.
The training by Kaguya could strengthen their relationship. They would be sharing a unique experience, facing the challenges of Kaguya's training together. This would likely create a deeper bond between them as they support and encourage each other through the difficult training.
Well, if Naruto absorbs Kaguya in a crossover fanfiction, it could drastically change the power balance. Naruto already has a lot of power, and adding Kaguya's abilities would make him nearly invincible. It might also change his relationships. His friends could be in awe or a bit scared of his newfound power. And it would surely change the way he faces future enemies. Instead of just fighting, he could potentially just overpower them with his new combined abilities.
The Naruto world would be turned upside down. With Naruto being raised by Kaguya, his understanding of chakra and the ninja way would be completely different. He might introduce new forms of jutsu based on Kaguya's ancient knowledge. The balance of power among the ninja clans would be disrupted. His upbringing by Kaguya could also lead to a change in the social structure of the ninja villages. For example, he might promote a more hierarchical system similar to what Kaguya might have been used to, instead of the more democratic - ish system that was in place in the original story.
The power dynamics would shift significantly. Naruto already being very powerful, with the connection to Kaguya, he might be seen as an even greater threat or asset. Allies and enemies would likely reevaluate their relationships with him.
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 some versions of fanfiction, Naruto might use a new and powerful sealing jutsu that he has either created or learned specifically for this purpose. It could be a jutsu that combines his Uzumaki heritage's sealing knowledge with his own unique chakra control.
It would change it completely. A godlike Naruto would have more power than Kaguya, so she would be in a position of relative weakness for once. This could make her more defensive or even fearful at first.
