Well, in fanfiction, one way could be that some Kumo ninjas are given the Sharingan as a gift or a curse from an ancient being. They then start to form a special group within the village dedicated to understanding and mastering the Sharingan. This group would share their knowledge with others, and over time, the Sharingan becomes an important part of Kumo's ninja heritage, with its own set of training methods and traditions.
One interesting storyline could be a character from Kumo who obtains the Sharingan through some mysterious means. Maybe they were part of a secret experiment that combined the powers of different ninja villages. This character then has to struggle with the new power, as it comes with a price, like a constant battle against the dark urges that the Sharingan can bring. They might also face discrimination from their own village who fear their new, unknown power.

In a Young Justice fanfiction, the Sharingan could be a power that a new character discovers. This character might be an experiment or have some sort of ancient heritage related to a hidden world.

They could use it to analyze the weaknesses of the villains they face, much like how it's used in Naruto.
In a fanfiction, the Sharingan could be a power - up for a Justice League member. For example, The Flash gets hit by a strange energy during a battle that gives him the Sharingan. With it, he can now not only run super - fast but also predict his opponents' moves better. This would make him an even more formidable opponent. The Sharingan's ability to copy techniques could also be translated into the Flash being able to quickly analyze and counter his enemies' fighting styles.
One way could be through a crossover character. Imagine a character from Naruto's world ending up in the Highschool DxD universe with their Sharingan. They could use it in battles against the devils and fallen angels in the Highschool DxD world. For example, the Sharingan's ability to predict movements would give them an edge in combat.

In a Sharingan Naruto Highschool DxD fanfiction, the Sharingan could also play a role in terms of illusions. Imagine a scenario where the character uses Sharingan - based illusions to deceive the enemies from both worlds. They could make a Highschool DxD devil believe they are in a completely different environment like a dangerous Naruto - style forest filled with traps. And for Naruto characters, they could be made to see illusions of their worst nightmares or false threats from the Highschool DxD world, which would make for some really intense and engaging storylines.
One way to incorporate Naruto's Rinne Sharingan in a Highschool DxD fanfiction could be through a crossover event.

For example, they could use the Rinne Sharingan's abilities to see through illusions in the Highschool DxD world which is full of magic and deception.
The Sharingan could be used to see through illusions created by the vampires in Rosario Vampire. Since vampires often have powers related to charm and mind - control, the Sharingan's ability to break illusions would be very useful.
