One possible development is that Naruto becomes a more vengeful character. The neglect from his family combined with the power of the Sharingan could make him angry and determined to show them up. Another is that he could become a loner, relying only on his own skills and the Sharingan. He might be hesitant to trust others at first. But as time goes on, he could learn to open up and form strong bonds with those who accept him for who he is.
For Naruto, he could become more self - reliant. Since he's being neglected by Yugao, he might start to focus more on his own growth as a ninja and as a person. He could learn to not rely on others for emotional support as much.
The fact that Naruto has Sharingan in this fanfic and is neglected by his family can greatly impact the plot. It could lead to Naruto being more self - reliant and having a darker, more brooding personality. He might be more driven to prove himself not just to the village but also to his family who shunned him. This could also change his relationships with other characters. For example, his bond with Sasuke might be different as they both have Sharingan and Sasuke could either be a rival or a reluctant ally. The plot could then focus on Naruto's journey to master the Sharingan and use it to gain the respect and love he never had from his family.
One possible plot development could be Naruto exploring his new bloodthirsty nature and how it affects his relationships with his friends. Maybe at first they are scared, but then they try to understand him. Another could be Naruto seeking revenge on his family for neglecting him, which might lead to some intense confrontations. And finally, he could find a new family among his comrades who accept him for who he is.
Well, one possibility is that Naruto's new Sharingan power could give him an edge in battles against stronger foes. He might be able to quickly analyze their moves and counter them more effectively.
A plot development could be that Kakashi discovers the root cause of Naruto's neglect. It might be related to some hidden secrets in the village. Then Kakashi has to fight against those who are behind Naruto's neglect while still training Naruto. Another development could be that Naruto and Kakashi form a very strong bond. Naruto then uses the skills and confidence he gained from Kakashi to face his enemies and also to try and change the village's attitude towards him.
Another aspect could be the relationship between Naruto and his sister. If she is the favored one, she might initially be oblivious to Naruto's pain. But as the story progresses, she could realize how wrong it is and try to make it up to him. This could lead to a complex family dynamic exploration in the fanfiction.
Anna could develop more patience as a mother. She was always a bit headstrong, but now she has to be more patient with her kids. Kristoff might become more open about his feelings as he is in a family environment. He used to be a bit of a loner, but now he has to communicate better with his family.
For Naruto, he would further develop his understanding and compassion. He would see that even the most seemingly evil characters have a backstory and reasons for their actions. This would make him even more determined to save everyone he can. For Tobi, his development would be huge. He could go from a revenge - driven, shadowy figure to someone who realizes the error of his ways and wants to make things right. He might learn about the value of life and friendship from Naruto.
He could develop a more serious and brooding personality. The white hair might be a constant reminder of a difficult event, causing him to be less carefree. For example, if he got the white hair from a near - death experience, he might be more cautious in battles and less likely to rush into things like he used to.
For Naruto, he could develop more patience and understanding. Usually he's quick to act, but being around Hana Inuzuka, he might learn to think things through more. Hana, on the other hand, could become more open - minded. She's from the Inuzuka clan which has its own set of traditions. Interacting with Naruto, who is quite different, could make her more accepting of new ideas. For example, Naruto's belief in never giving up on anyone could influence her to be more inclusive towards others in the village.
