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.
Power is a common theme. Since the Sharingan gives its wielder special abilities, many fanfics explore how characters gain, control, and use that power. Another theme is redemption. Given the Uchiha clan's history in Naruto, some fanfics focus on characters redeeming themselves or their clan through the use of the Sharingan.
In a fanfiction, an OC Uchiha born with an activated Sharingan could face unique challenges. The Sharingan drains chakra, and being born with it activated might mean they have to learn early on how to manage their chakra levels more effectively. Also, they could attract unwanted attention, either from jealous clan members or from enemies who see them as a threat due to their special ability.
One great fem Naruto with Uchiha Sharingan fanfiction is 'The New Path of a Female Naruto'. It explores how a female Naruto, who somehow obtains the Sharingan, changes the Naruto universe. The story has really interesting character developments and unique plot twists.
Imagine a ninja from another land who met Sasuke during a battle. She was a strong and independent fighter. After the battle, she was intrigued by Sasuke's skills and his complex personality. She started to seek him out, and they had many encounters. At first, Sasuke was dismissive, but her persistence and the unique bond they formed over time led to love. Their relationship was not easy, with Sasuke's past always looming, but their love prevailed in the end.
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.
Yes, there are many. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Naruto Eternal Sharingan Sasuke' and you'll find a bunch of them, but the quality may vary.
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.
Another theme is self - discovery. As Sasuke travels and faces various challenges, he gradually discovers more about himself, his powers, and his place in the ninja world. This is shown through his internal monologues and his reactions to different situations in the novels.
In Sasuke Uchiha lemon fanfics, he may be depicted with a more passionate side when it comes to love and relationships. His usual cold exterior might be softened to show his vulnerability in the context of these often - romantic and physical interactions. However, this is a deviation from his traditional character in the Naruto series where his main goals are related to power and vengeance. These fanfics often explore his character in a more romantic and sometimes sexually - charged way that is not part of the original story.
