Well, if Naruto had the Sharigan in a fanfiction, it could completely change the power dynamics. He'd have access to powerful jutsu like Amaterasu or Tsukuyomi. This would make him even more of a force to be reckoned with against his enemies. Maybe it could also lead to some interesting interactions with Sasuke, who already has the Sharigan. It could also open up new storylines where Naruto has to learn to control this new power, and how it might affect his relationships with his friends and the Hidden Leaf Village.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
Maybe Itachi saw Naruto as a potential force for good in the ninja world. He might have thought that giving Naruto the Sharingan would make him strong enough to protect the village and bring peace.
The fanfiction could explore how Obito's identity revelation affects his relationship with the Akatsuki. Some members may feel used or deceived, while others might see it as an opportunity. It could also show how Obito's true self starts to form new bonds or break old ones within the organization, depending on how his true intentions are perceived.
One possible motive could be to use Sakura as a bargaining chip. If he has some sort of plan against Naruto or the Hidden Leaf Village, Sakura, being a close comrade of Naruto, could be very useful. He might think that by restraining her, he can force Naruto to come to a certain location or make concessions.
Well, initially, Naruto might be confused by the Sharigan. It's a power he didn't grow up with. But as he starts to explore it, he could become more strategic in battles. His character would develop a new sense of caution. He'd also have to deal with the envy or fear from others, which would force him to mature in different ways. For example, he might have to be more diplomatic to ease the concerns of the Hidden Leaf villagers who are wary of the Sharigan's power.
One popular sakura and obito fanfiction is 'The Unseen Bond'. It delves into a world where Sakura discovers Obito's hidden past and tries to help him find redemption. Another great one could be 'Sakura's Encounter with Obito', which focuses on their chance meetings and how it gradually changes their relationship. And there's also 'A New Path for Sakura and Obito' that shows them working together to face challenges in the ninja world.
The sad story of Obito and Rin is a key part of the Naruto narrative. Obito was a young ninja with big dreams and a huge crush on Rin. When Rin was seemingly killed in front of him, it shattered his world. He thought that the ninja world was full of pain and betrayal. This led him to be influenced by Madara. He became one of the main antagonists, all because of his love for Rin and the unbearable pain of losing her. His journey from a hopeful young ninja to a vengeful villain is a tragic consequence of Rin's death.
Well, it could be about Sakura somehow being related to Obito in a reincarnation context. Maybe it involves Sakura having memories or powers that are linked to Obito from a past life. It might explore how this new connection changes their relationship in the Naruto universe, like if Sakura starts to understand Obito's past actions better or if she gains new abilities because of this reincarnation bond.
