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.
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.
Well, in such a fanfiction, one possibility is that Naruto would inherit some of the Sharingan's powers through their brotherly bond. Since they are so close, Sasuke's Sharingan might react differently to Naruto. It could give Naruto an ability to see chakra in a new way, similar to how the Sharingan works. This would be a really cool addition to Naruto's existing powers and would make their battles more interesting.
One great fanfiction could be about Naruto and Sasuke growing up as brothers and discovering the power of the Sharingan together. They might face challenges like protecting their village from a new and powerful enemy. The Sharingan could give them an edge in battle, and their brotherly bond could be a source of strength for both of them.
Yes, in some fanfictions, Naruto might end up having Sasuke's Sharingan through various creative plot devices. For example, in a story where there's a powerful jutsu gone wrong that transfers Sasuke's abilities, including his Sharingan, to Naruto. This can lead to really interesting character developments as Naruto has to learn to control and use this new power.
One common theme is the power struggle. Since the Sharingan is a very powerful ability, many fanfictions explore how Naruto and Sasuke deal with the power that comes with it. For example, they might struggle with the temptation to misuse it or have to learn to control it.
One idea could be a story where Sasuke, with his Sharingan, discovers a new power related to the Rinnegan that was hidden within Naruto all along. Maybe Naruto has some dormant Sage of Six Paths energy that when combined with Sasuke's powers, they can unlock a new level of strength to fight a powerful, unknown enemy.
Another theme is the bond between Naruto and Sasuke. Since the Sharingan can be a connection between them in some fanfictions, it's often used to explore their relationship. It could be about how they understand each other better through the Sharingan, or how it helps them to forgive and trust each other again. For instance, in some stories, the Sharingan reveals hidden emotions and memories that strengthen their bond.
One way could be through a kekkei genkai transfer jutsu. If a powerful ninja, perhaps an old hermit with knowledge of ancient jutsus, decides to transfer Sasuke's Sharingan to Naruto for the greater good of the village. This jutsu might be risky but in the world of fanfiction, anything is possible.
One possible fanfiction could be where Naruto, through some strange and unforeseen circumstances, like a powerful jutsu gone wrong that somehow transfers Sasuke's Sharingan to him. Naruto then uses this new - found power in ways that make Sasuke respect him more. For example, Naruto might use the Sharingan's ability to predict movements to counter an enemy's attack and save Sasuke, leading to a stronger bond between them.
