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.
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.
One possible scenario in such a fanfic could be that Itachi, seeing Naruto's potential and his pure heart, decides to entrust Naruto with his Sharingan. This could potentially give Naruto new abilities and a deeper understanding of the Uchiha clan's power. It might also create a unique bond between Naruto and the memory of Itachi, leading to new storylines where Naruto uses the Sharingan's powers in unexpected ways.
A good Naruto Sharingan Itachi fanfic should have a deep understanding of Itachi's character. His motives, like protecting Konoha at all costs, should be well - explored. Also, the power of the Sharingan should be accurately depicted, for example, showing how he could use genjutsu with it.
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.
One great 'Naruto Sharingan Itachi fanfiction' is 'The Redemption of Itachi'. It delves into Itachi's complex character, exploring his motives and the internal struggles he faced. Another interesting one is 'Itachi's Hidden Path' which shows an alternate timeline where Itachi makes different choices. There's also 'Sharingan's Legacy: Itachi' that focuses on how his Sharingan abilities impact the story in new and unexpected ways.
One way could be through a powerful jutsu gone wrong. Maybe a jutsu that was meant to transfer Itachi's memories to Naruto accidentally transferred his Sharingan as well. In the world of fanfiction, there are often many creative and out - of - the - box explanations.
