A possible fanfiction plot could involve Naruto and Sai being brothers in a parallel universe. In this universe, they are both part of a special shinobi team from the start. Sai's artistic abilities combined with Naruto's determination make them an unbeatable duo. They face challenges together, like protecting their village from a new and powerful threat, all while exploring their newfound brotherly relationship.
A fanfiction could be about Sai trying to befriend Sasuke. Sai, who is often socially awkward, attempts to break through Sasuke's cold exterior. Meanwhile, Naruto is caught in the middle, trying to help Sai while also dealing with his own complex relationship with Sasuke. It could be a story full of humor and some tense moments.
One idea could be a story about their team training. Naruto's enthusiasm, Sasuke's intensity and Sai's unique combat style could lead to interesting training scenarios. They could learn from each other's strengths and overcome their weaknesses together.
Their relationship could develop slowly. At first, Sai might not understand Naruto's boisterous nature. But as they spend more time together, Sai would start to see the value in Naruto's loyalty and determination. Naruto, on the other hand, would help Sai open up emotionally.
One idea could be a story where Naruto and the Lee brothers team up for a special mission. They could face a powerful enemy that requires their combined skills. Naruto's jutsus and the Lee brothers' taijutsu would make for an exciting battle sequence.
One idea could be that they discover they are brothers in a hidden past plot twist. Maybe their parents were from different villages but fell in love secretly. As brothers, they could team up to face a new and powerful enemy that neither could defeat alone.
One plot idea could be Fem Naruto and Sai going on a mission together in a foreign land. They encounter strange new enemies and have to rely on each other's unique skills. Sai, with his art-based jutsu, and Fem Naruto with her strength and determination. Another idea is a story where they are both training under a new master who has a very different style of teaching compared to what they are used to. This could lead to a lot of character growth and new jutsu development for both of them.
Maybe they both have a common enemy that forces them to team up and during their journey, they start to feel a strong bond that makes them suspect they might be related. They could then start to explore their pasts and find out that they have the same father or mother who was involved in some sort of cross - dimensional love story.
One plot idea could be Sai trying to understand the deep bond between Naruto, Sakura and Sasuke. He might initially struggle as he has his own unique upbringing. For example, he could be assigned a mission with the three of them and slowly learn about their history, like Naruto's determination to bring Sasuke back and Sakura's unrequited love for Sasuke in the beginning. This could lead to Sai having a new perspective on friendship and loyalty.
There's a fanfic called 'Sai and the Art of Friendship'. In this story, Sai tries to form real friendships within the Naruto gang. It has some really heart - warming moments as he struggles to adapt to the group's dynamics.
One idea could be Naruto and Kurama going on a journey to discover Kurama's past before being sealed. Another could be them facing a new enemy together that only their combined strength as 'brothers' can defeat. Maybe a story where they have to switch places, with Naruto being in Kurama's mind -scape and Kurama having to live in Naruto's world for a while.
