The plot implications are numerous. For starters, Naruto's training would take a different turn. He would have to learn how to control and master the Sharingan, which could involve seeking out Uchiha - related knowledge or training from someone like Kakashi. This could lead to new story arcs. Additionally, the village's perception of Naruto would change. Some might see him as a threat due to the Sharingan's power and the Uchiha's past. This could create internal conflicts within the village. Moreover, Naruto's enemies would have to re - evaluate their strategies against him, leading to more intense battles and power - up races in the fanfiction.
Well, Naruto's abilities would change drastically. The Sharingan gives the user enhanced perception, which would make Naruto even more formidable in combat. He could potentially predict his opponents' moves better. Also, with the Sharingan's ability to copy jutsu, Naruto might be able to learn and use new techniques more quickly. However, he would also have to deal with the potential negative effects of the Sharingan, like overusing it and straining his eyes.
In some fanfictions, it could be through a special jutsu or ritual. Maybe Itachi, before his death, transferred his Sharingan to Naruto in a unique way, perhaps using a forbidden technique that was known only to a few in the Uchiha clan.
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 possible fanfiction could be that Itachi, on his deathbed, decides to transfer his Sharingan to Naruto. He sees in Naruto the potential to change the Uchiha's fate and the ninja world. Naruto, with the Sharingan, gains new abilities like enhanced perception and the ability to copy some jutsus more easily. He uses this new power to better understand the Uchiha and bridge the gap between them and the rest of the village.
They could develop a mentor - mentee relationship. Itachi uses his knowledge of the Sharingan to teach Naruto new combat techniques. As they train together, they bond over their shared experiences of loss and their desire to protect the people they care about. Naruto might also help Itachi come to terms with his past actions and find some peace within himself.
Well, in a fanfiction where Naruto is trained by Itachi in Sharingan, Naruto would first have to adapt to the new power. Itachi would probably start with the basics of how to activate and control the Sharingan. Since Naruto is used to his own physical and chakra - based training, this would be a challenge. However, with Itachi's guidance, he could master it. Once he does, he could use the Sharingan to analyze his opponents' fighting styles better. For example, he could quickly figure out the weaknesses in an enemy's jutsu and counter them effectively. He could also use the Sharingan's visual prowess to enhance his reaction time during battles.
Itachi is such an interesting character in the Naruto series. His Sharingan abilities are cool and powerful. In fanfiction, writers can expand on his story, his relationships, and his inner thoughts. For example, they can explore his relationship with Sasuke in new ways or show how he developed his Sharingan skills. Also, the idea of Itachi as a tragic hero makes people want to read more about him in fanfiction.
I really liked 'Itachi's Hidden Truths'. In this fanfic, the author gives a different perspective on Itachi's actions. It shows how his Sharingan abilities were not just for combat but also for protecting those he cared about in his own, often misunderstood, way.
