One idea could be a story where Obito's mask holds a hidden power. For example, it could be a key to an ancient jutsu that was sealed away long ago. Another plot could involve a character trying to steal the mask for its significance in the ninja world.
One possible fanfiction could be about Naruto and Obito teaming up to face a new, powerful enemy. They could combine their unique skills, like Naruto's Rasengan and Obito's Kamui. Their relationship could start off rocky due to their past differences but gradually turn into a strong bond as they fight side by side.
In the 'naruto has a mask fanfiction', it might be that Naruto finds the mask himself. He could stumble upon it during one of his adventures, perhaps in an ancient ruin or a hidden cave. The mask could be enchanted or have some special property that draws Naruto to it, and he decides to keep it and figure out its secrets on his own.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
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.
One great 'Naruto and Obito Fanfiction' is 'The Redemption of Obito'. It explores Obito's journey towards redemption in a really interesting way, showing how his relationship with Naruto could potentially change his fate. Another one is 'Naruto and Obito: A New Bond' which focuses on them forming an unexpected alliance and facing new threats together. There's also 'Obito's Second Chance with Naruto' that delves into Obito getting a chance to make things right with Naruto's help.
Their friendship in fanfiction could be really interesting. Maybe they start as rivals but then realize they have a common goal. For example, protecting the Hidden Leaf. They could learn from each other's jutsu. Naruto could learn about space - time ninjutsu from Obito while Obito could learn about Naruto's positive attitude towards life.
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.
I really like 'Obito's New Path'. In this fanfiction, Obito gets a second chance in a different reality. His Sharingan abilities are explored in unique ways, like how he uses it to understand the true nature of the ninja world. The story also has great character development for Obito and other Naruto characters.
