This change in Naruto having one eye could lead to a whole new character arc. Maybe he'd be more self - conscious about his appearance, which could affect his relationships. He might also develop new jutsu that are more suitable for his one - eyed state, like a jutsu that uses his remaining eye's chakra in a more focused way.
In a fanfiction where Naruto has the Rinnegan, it might change his relationships too. His friends could be both in awe and a bit scared of his new power. The villages might see him as an even greater threat or a more reliable protector. Also, his training would have to be different. He'd need to learn how to control and master the Rinnegan's abilities, which are very different from the chakra nature he was used to.
In terms of his romantic relationships, if there were any potential love interests, they might be more hesitant. However, Naruto's determination and positive attitude could still win them over. His relationships with his teammates from Team 7 would likely shift. They would need to adjust their battle strategies to account for his one - eyed state. His bond with Hinata could also be tested as she might worry more about his safety and his ability to protect himself and the village.
Having Naruto with a Hyuga eye in fanfiction would completely transform his ninja abilities. The Byakugan allows for seeing the chakra points in the body, so Naruto could potentially use this to his advantage in combat by targeting those points more precisely. In the story, it could also affect his character development. He might become more perceptive and less impulsive because of the insights the Byakugan gives him. Moreover, it could lead to some cool crossovers within the Naruto universe. For example, he could team up with Hinata in a more unique way, using their combined Hyuga - related powers to take on stronger enemies. It would be a really exciting twist to the original Naruto storyline.
It could be due to a battle injury. Maybe he got into a really tough fight with a powerful enemy, and in the process, lost an eye. For instance, a fight against a rogue Akatsuki member who has a very dangerous eye - related jutsu.
It might be due to some sort of bloodline fusion. Naruto is known for his Uzumaki heritage, but perhaps there was an unexpected encounter with another clan's power that merged with his own, and as a result, one of his eyes turned red as a new and unique ability emerged.
This change could bring them closer in a strange way. Naruto, with Sasuke's eye, might start to see the world more like Sasuke does. He could understand the reasons behind Sasuke's actions better. Sasuke, on the other hand, might be a bit shocked at first but then realize that Naruto is now even more intertwined with his being. This could lead to them having more in - depth conversations and a rebuilding of their trust.
His relationships could change quite a bit. His friends might be a bit intimidated at first. For example, Sakura might be worried about this new, unknown power. But over time, they would probably come to accept it. His enemies, on the other hand, would be more cautious around him.
Well, it could make Naruto extremely powerful right from the start. With the Rinnegan, he might be able to master all types of jutsu more quickly. He could also have an edge in battles against powerful foes like Madara or Kaguya. Maybe he'd be able to use the six paths techniques with more ease and less training.
In a fanfiction where Naruto has leukemia, the plot could take a very different turn. Naruto's usual exuberance and energy would be dampened by his illness. His fights would be more difficult as he would have to deal with the physical weakness brought on by leukemia. The story could focus more on his internal struggle, his fear of dying before achieving his dreams. His friends like Sasuke might have a change of heart seeing Naruto so vulnerable. It could also lead to new alliances in the ninja world as different clans might come together to try and find a cure for Naruto's condition.
If Naruto had a third eye in fanfiction, it could greatly enhance his perception abilities. He might be able to detect hidden enemies or traps more easily. For example, in battles, he could see chakra movements from all directions without having to rely so much on his regular senses. This could make him even more formidable in combat and change the dynamics of his fights against powerful foes like Sasuke or Pain.
