In these fanfictions, the idea of Naruto with the Sharingan opens up a whole new world of possibilities for his abilities. Kushina, on the other hand, has her own strong personality and backstory. When you mix these two elements, you get stories that can explore things like Naruto's growth in a different way. For example, how he uses his Sharingan - influenced powers to protect the things Kushina holds dear, like the village. It also allows for unique storylines about family bonds and the power of heritage.
One popular 'sharingan naruto x kushina fanfiction' might be 'The Hidden Bond'. In it, the unique relationship between Naruto with the Sharingan ability and Kushina is explored in a way that delves deep into their characters. It often shows Naruto's newfound powers and how Kushina reacts to this different side of him, adding a lot of emotional depth to their interactions.
Family and legacy are also common themes. These fanfictions could explore how Kushina's relationship with Naruto affects his understanding of the Sharingan if there are some unforeseen connections. It might also look at how the legacy of the Uzumaki and Uchiha clans are intertwined through Kushina and the Sharingan, perhaps showing how past events in the clans' histories are related to present - day situations in the story.
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.
Another aspect could be that the fanfiction delves into how Kushina's presence affects Naruto's relationships with others. For instance, his relationship with Sasuke could be different. With a strong maternal figure in his life, Naruto might be more stable emotionally and be able to approach Sasuke in a more understanding way, which could potentially change the whole dynamic of their rivalry and friendship.
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.
There's a fanfiction titled 'Kushina's Link to the Sharingan'. It could potentially show a backstory where Kushina had an encounter with an early Uchiha, and this led to some sort of bond or influence on the Sharingan. It might also include how her own abilities as a Jinchuriki affected the Sharingan's capabilities in the story.
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.
One drawback could be the strain on his body. The Sharingan is a powerful dojutsu, and Naruto's body, which is used to his own chakra system, might not be able to handle it well at first. This could lead to fatigue and over - exertion during battles.
In this fanfiction concept, Naruto and Sasuke as brothers could lead to a very different Naruto universe. With Sasuke having the Sharingan, he could potentially use it to protect Naruto more often. Maybe they would train together in new ways, combining Sasuke's Sharingan - related jutsu with Naruto's Uzumaki power. For example, Sasuke could use his Sharingan to analyze Naruto's chakra flow and help him master new forms of the Rasengan faster.
