Well, when the Sharingan is neglected in fanfiction, it can lead to a less diverse range of powers and abilities being represented. The Sharingan has unique abilities like predicting movements and copying jutsu, and without it, stories may lack that kind of strategic and combat - related depth. Also, it can make the Uchiha clan seem less important in the fan - created Naruto universe, which goes against the significance they have in the original series.
If the Sharingan is neglected in Naruto fanfiction, the stories might lose out on some of the most iconic and visually appealing elements of the Naruto world. The design of the Sharingan itself is quite cool, and not using it means not being able to take advantage of that in terms of creating exciting fight scenes or moments of revelation. Moreover, it can limit the exploration of the relationship between the Uchiha clan and other ninja clans, as the Sharingan is a big part of what makes the Uchiha unique.
One consequence is that the richness of the Naruto universe isn't fully explored. The Rinnegan has unique abilities and a deep backstory, so neglecting it means missing out on those aspects. It can also lead to less diverse storylines, as the Rinnegan could have introduced new plot twists and power dynamics.
He might have increased visual abilities. For example, he could see chakra flow more clearly, which would be a great advantage in battle.
The consequences could be far - reaching in the fanfiction. Naruto's relationship with Kakashi might change. There could be a deeper sense of respect and a new kind of bond formed because of this transfer. In terms of power, Naruto could unlock new jutsus or abilities that are related to the Sharingan. He might be able to combine his existing Rasengan techniques with the Sharingan - enhanced perception. This could make him an even more formidable opponent. However, it could also put a strain on his body. The Sharingan is known to consume a lot of chakra, and Naruto's body might need to adapt to this new power drain. If he overuses it, it could lead to exhaustion or even long - term damage.
He would gain new visual abilities. Naruto could now use the Sharingan's powers like predicting movements, copying jutsus more easily. But it might also come with some drawbacks. For example, the Sharingan consumes a lot of chakra, so Naruto would have to manage his energy better.
In a fanfiction, if Naruto gets Shisui's Sharingan, he might face consequences in his training. He would need to learn how to control and master this new power, which could take time away from his normal training. This could potentially slow down his progress in other areas, like his Rasengan training or his control over the Nine - Tails' chakra. Also, his relationships with his non - Uchiha friends might be affected. They could feel left out or less important to Naruto now that he has this powerful Uchiha ability.
One possible consequence is that Naruto would gain enhanced visual abilities. The Sharingan can see chakra flow clearly, which would be a great asset in battle for Naruto. He could better analyze his opponents' moves and weaknesses.
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.
One reason could be the realisation of the strong bond they could have had. Kushina might understand in the fanfiction that Naruto has been through so much alone, and she missed out on being there for him. She may regret not being able to protect him from the hardships and bullying he faced as a child.
Minato fanfiction can avoid neglecting Naruto by making sure to connect their stories. For example, Minato's actions could be shown to have a direct impact on Naruto's life. Maybe Minato made a choice that later affected the village Naruto grew up in.
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.
