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.
If Naruto had a Sharingan in fanfiction, it would drastically change the story. He could quickly copy enemy jutsus like Sasuke. His combat ability would skyrocket as he could predict movements better. Also, his relationships might change. For example, his bond with Sasuke could be different as they'd both have the Sharingan. It would also make his training with Kakashi more interesting as Kakashi could teach him unique Sharingan - related techniques.
Well, it could make Naruto more cautious. Losing an eye is a huge deal. He might be less reckless in battles as he now has a physical vulnerability. He could also become more determined to prove himself despite the setback.
Well, if Naruto had the Sharingan and Byakugan, his combat abilities would skyrocket. The Sharingan could help him copy enemy jutsus more effectively, and the Byakugan would give him near - 360 - degree vision. This would make him even more of a force to be reckoned with in battles against the Akatsuki. He could anticipate attacks better and counter with his own powerful jutsus. It would also change his relationships, as his new powers might make some characters jealous or more eager to team up with him.
In a fanfiction scenario where Naruto has throat cancer, the story could take a very different turn. Firstly, his training methods would need to be adjusted. Since he couldn't use his voice effectively, he might focus more on silent or less vocal forms of combat. His social interactions within the village would change too. People might pity him or look at him differently. His role as a ninja might shift from being a front - line fighter to more of a strategist, as his physical condition restricts his combat capabilities. His fight against the illness could also become a parallel battle to his fight against the villains in the Naruto universe.
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.
One possible plot could be that Naruto discovers he has a Byakugan eye through some strange encounter or experiment gone wrong. This new power could initially be a source of confusion for him as he tries to figure out how to control it. He might seek out the Hyuga clan for help, and there could be a whole arc about him learning the ways of the Byakugan while still maintaining his own unique ninja style.
In a fanfiction, if Naruto has the Jagan Eye, it could change his relationships with his enemies too. For example, Orochimaru might be more interested in Naruto now. He could try to manipulate Naruto into using the Jagan Eye for his own evil purposes. Naruto, on the other hand, would be determined not to let the power corrupt him and would use it to protect the Hidden Leaf Village and the whole ninja world from new threats that are emerging because of his new power.
One possible storyline could be that Naruto somehow gains a Hyuuga eye through a unique experiment gone wrong. This new power could initially be difficult for him to control, as the Hyuuga eye has its own set of abilities like the Byakugan. He might struggle to adapt to the sudden change in his vision and the new skills it brings, such as seeing the chakra points clearly. This could lead to some comical moments as he accidentally activates the eye at inappropriate times, but also some intense battles where he slowly learns to master this new power and use it in combination with his existing Rasengan and other techniques.
Well, in a fanfiction where Naruto has Sans eye, it could start with Naruto finding himself in a dimension where he's given this strange power. The Sans eye might give him a new perspective on the concept of chakra, perhaps seeing it in a different form or being able to manipulate it in ways he couldn't before. He could use this new power to better understand his enemies and their motives, and it could also create some interesting interactions with his friends who would be both amazed and a bit wary of this new power.
