Itachi also features prominently. His powerful Sharingan and his complex character make him a favorite for fanfiction writers. They might write about his past and how his Sharingan abilities influenced his actions in ways not fully explored in the original series.
Some fanfictions might introduce new or original characters with the Sharingan. These characters could be hybrids or have a unique backstory that ties into the power of the Sharingan. They then interact with the well - known Naruto characters, adding new dynamics to the story.
Sasuke is often a popular character in such fanfictions. Since he already has the Sharingan in the original Naruto series, it's easy to expand on his powers and make him even more powerful with a godlike Sharingan. Fans love to see how he would handle this new level of power and how it would change his relationships with other characters.
Itachi is also a popular choice. Even though he was initially portrayed as a complex character with his own moral code in the original series, fanfiction writers might explore a scenario where he fully embraces the 'evil' side of the Sharingan. This could involve him using it for more malevolent purposes than what was shown in the anime or manga, perhaps using it to manipulate events on a grander scale for his own ends.
Sasuke is often very popular. His Sharingan abilities are quite powerful and his brooding personality makes for interesting crossovers. Writers can put him in different situations where he has to use his Sharingan in new ways.
Sasuke is often a popular character in such fanfictions. His natural Sharingan abilities make it interesting to explore how he would interact with the Rinnegan powers. Fans like to write about him achieving new levels of power by combining or evolving his Sharingan in relation to the Rinnegan.
Madara Uchiha is another popular character in Naruto Rinne Sharingan fanfiction. Since he was one of the first characters to be associated with the Rinnegan (a precursor to the Rinne Sharingan in some ways), fans are interested in seeing how his character would be even more powerful or how his motives might change if he had the Rinne Sharingan. There are often stories that revolve around his further rise to power or his redemption with the help of this powerful eye ability.
Sasuke is often a very popular character in such fanfiction. His original connection to the Sharingan in the Naruto series makes him a natural fit for stories centered around the Mangekyou Sharingan. Another popular character could be Itachi, as his use of the Mangekyou Sharingan was quite significant in the original story, and fanfiction writers like to explore more of his untold stories or alternate scenarios.
One interesting concept could be unique Sharingan abilities not seen in the original Naruto series. For example, a Sharingan that can not only predict movements but also manipulate time on a small scale.
Itachi Uchiha is also extremely popular. His tragic backstory and his powerful use of the Sharingan make him a prime candidate for fanfic exploration. Writers might create stories that expand on his time in the Akatsuki or his relationship with Sasuke before his death.
In many Naruto fanfictions, Itachi is often depicted as an extremely powerful Mangekyou Sharingan user. His original abilities in the canon, like Amaterasu, are further enhanced in fan works. Sasuke is also a common focus. His Mangekyou Sharingan's powers can vary greatly from one fanfiction to another, sometimes with new and unique jutsu created by the authors. Another character could be Madara. Fanfiction writers love to explore the full potential of his Mangekyou Sharingan, often giving him abilities that were only hinted at in the original series.
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.
