One reason could be that some fanfiction authors might focus more on other aspects like new jutsu or character relationships outside of the Uchiha clan. They may not fully understand the potential of Sharingan, which has a wide range of abilities from basic perception enhancement to powerful genjutsu. Another factor could be the over - popularity of some other elements in the Naruto universe, like the tailed beasts, which overshadow the Sharingan in their stories.
Well, one idea could be exploring a scenario where Sasuke's Sharingan is overlooked by the village in a different way than in the original story. Maybe they see it as more of a curse than a power and try to suppress it, which could lead to a whole new set of conflicts for Sasuke.
Sometimes Naruto can also be a main character in these fanfictions. He might be the one who notices the neglect of Sasuke's Sharingan and tries to help him in some way. Their friendship could be explored in a new light, with Naruto being more proactive in understanding and supporting Sasuke's power.
One good 'Naruto Rinne Sharingan Neglected' fanfiction could be 'The Forgotten Power'. It delves into the potential of the Rinne Sharingan that was overlooked in the original series. It might explore how a character discovers new abilities related to it and how it changes the Naruto universe's power dynamics.
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.
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.
Well, one reason could be that it's a very powerful and complex ability. Writers might be intimidated by trying to incorporate it into their stories without making it overpowered or without fully understanding its mechanics. So, they tend to focus on more well - known and easier - to - write - about powers in Naruto.
In fanfiction, Naruto could get the Sharingan through a blood - related connection that is revealed later. For example, it could be discovered that he has some distant Uchiha ancestry that gets activated somehow. Maybe a powerful enemy's attack awakens this dormant Uchiha blood in him, and as a result, he develops the Sharingan. It could also be that a powerful sage or a new character uses their own unique powers to bestow the Sharingan upon Naruto for a specific purpose.
If Naruto had the Sharingan in fanfiction, it would likely lead to some interesting power - up scenarios. He could combine the power of the Sharingan with his own massive chakra reserves. This might make him an even more formidable opponent. His training would also take a new turn as he'd have to learn to control and master the Sharingan's abilities, like the different levels of the Sharingan and their unique powers.
Naruto might adapt by first trying to understand the basic functions of the Sharingan. He could start with the simple ability to see chakra flow more clearly. Since he has always been perceptive about people's emotions, he could use the Sharingan to read the emotions of his enemies through their chakra, which would help him in battles.
