If Naruto takes Nagato's eyes in fanfiction, the development could be quite dramatic. Naruto would need to train to master the powers of the eyes. This could lead to him going on a journey to secluded places to practice without endangering others. His friends might try to help him, but they may also be in over their heads. Enemies could band together to try and take the eyes from Naruto, seeing it as an opportunity to gain ultimate power for themselves. This would create a lot of action - packed and tense situations in the story.
If Naruto were to take Nagato's eyes in fanfiction, it would be a game - changer. Naruto is known for his strong will and determination. With the addition of Nagato's eyes, he could potentially use the Rinnegan's powers in ways that Nagato never did. He could combine his own Uzumaki chakra with the power of the eyes to perform new and unheard - of jutsu. This could also create a new dynamic in the story, as Naruto would now have to face new enemies who are interested in his newfound power, while also trying to uphold his values of friendship and peace.
It can greatly affect the plot. It might lead to Naruto becoming a more powerful force against the remaining threats in the ninja world. His new power could change the balance of power, making some villains more cautious or more desperate to stop him. It could also lead to new alliances being formed as other villages might see Naruto as an even greater asset or threat.
Naruto's character could become more conflicted. He has always been about hope and friendship, but being related to Nagato might make him question his own beliefs. He might start to see the world in a more nuanced way, understanding that there are reasons behind Nagato's actions that he previously didn't fully consider.
The storyline could start with the discovery of their brotherhood. This would shock both of them as they have been on opposite sides. Then, Naruto would try to convince Nagato to change his ways. Nagato might resist at first, but as he sees Naruto's determination, he would start to question his own actions. Along the way, they might face challenges from other shinobi who don't trust Nagato. But Naruto would protect his brother and they would gradually gain allies. Eventually, they could work towards a new future for the shinobi world, one based on understanding and cooperation.
In a fanfic where Naruto takes Nagato's eyes, he might gain new and powerful abilities. For example, he could potentially access the Rinnegan's powers more directly. This could make him even stronger in combat, perhaps allowing him to use abilities like the Six Paths Techniques with greater ease. It could also change his relationships with other characters. Some might be in awe of his new power, while others could be afraid or jealous.
The story would become much more intense. Naruto would suddenly have access to powers that were previously exclusive to the Uchiha. This would shift the power balance in the ninja world.
Well, if Naruto was the son of Serafall and Nagato in this fanfiction, the story could start with Naruto having a very different upbringing. He might inherit some of Serafall's magical abilities and Nagato's rinnegan - like powers. This could make him an even more powerful ninja. Maybe he would be shunned at first in the Hidden Leaf Village because of his strange origin, but as he grows, he uses his unique powers to protect the village and gain acceptance.
It might develop with Naruto being initially confused and a bit angry at being taken away. But as Minato starts to show him new techniques or tell him stories about his past, Naruto would gradually come to understand. For example, Minato could show Naruto how to better control his chakra, which would be a major development in the fanfiction. And as they spend more time together, their father - son relationship would strengthen, which would be a central part of the story's development.
At first, it could be a bit rocky. Nagato has been through a lot and his views are quite different from Naruto's. But as they start to communicate and learn about their family tie, they might gradually build trust. Naruto would probably be the more open - minded one at the start, trying to reach out to Nagato. Nagato, on the other hand, would be more hesitant but slowly be drawn in by Naruto's sincerity.
His character would become more complex. Naruto has always been about hard work and believing in oneself, but with the Rinnegan training, he'd have to grapple with new levels of power. He might become more cautious as he realizes the potential destruction the Rinnegan can cause if misused.
