One great fanfiction about Obito being revealed in Naruto could be one where his true motives are slowly uncovered not just by Kakashi, but by the entire ninja world. It could start with small hints that the Akatsuki's actions are somehow related to Obito's past and his broken dreams. As the story unfolds, characters like Naruto start to put the pieces together, realizing that Obito is not just a random enemy but a product of the shinobi world's failures. This type of fanfiction often delves deep into Obito's psyche, exploring his love for Rin and how it was twisted into hatred after her death.
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 plot twist could be that Obito was actually being controlled by a more powerful force all along. When his identity is revealed, it seems like he's the mastermind, but later it's discovered that he was just a puppet. Another twist could be that Obito has a secret alliance with a character that no one expected, like a member of the Leaf Village elders. This alliance was formed for a reason that is only revealed later in the story.
Perhaps in the fanfiction, Obito's identity is revealed to be a double agent for a group that was thought to be extinct. This changes the way other characters view him and the overall power dynamics in the story. He could have been working towards a different goal than what was initially assumed.
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.
There could also be interactions with the new generation of ninjas. They might view Obito as a sort of legend or a cautionary tale. Their fresh perspectives could either inspire Obito to change further or make him feel even more out of place in this new post - war ninja world.
Well, the reborn character could explore Obito's Sharingan powers in new ways. Instead of using them mainly for combat like Obito did in the original story, they could focus on using the Sharingan to understand the emotions of others. For example, they could use it to detect lies and hidden motives, which would be a unique twist on the power.
Besides Obito, Sasuke could be a main character in this fanfiction. Sasuke, with his own journey of redemption and his understanding of power and the ninja world, could have an interesting dynamic with the reincarnated Obito. Also, Sakura might play a role. She could be the one who tries to heal the reincarnated Obito, both physically if he is injured during his new adventures and emotionally from the traumas of his past life.
Often, Obito is attracted to Kushina's strength and kindness. He might try to impress her with his own abilities. Their interactions could involve Obito being a bit clumsy in his attempts at first. Kushina, on the other hand, might find his eagerness endearing and start to open up to him more. They could share stories about their pasts, their dreams, which deepens their bond.
