What could be the plot of a 'naruto joins sasuke fanfiction'?

It could be an old enemy who has resurfaced, like Orochimaru again. Since Naruto and Sasuke are together now, Orochimaru might see them as a threat to his own plans for power and immortality.

One possible plot could be Sasuke initially being a bit of an outcast in Fairy Tail because of his brooding nature. But as he goes on quests with the guild members, he starts to open up. For example, he might team up with Natsu for a mission where they have to fight a powerful dark wizard. Through their battles and interactions, Sasuke learns about the power of friendship in Fairy Tail, which is very different from his past experiences in Naruto's world.

Well, in this fanfiction, Naruto could join Esdeath in her military campaigns. Since Naruto has his own set of powerful jutsu, he could be a great asset. The plot could revolve around how Naruto adapts to the new world's rules and politics. He might be shocked by the harshness of Esdeath's world but still tries to bring some of his positive values. They could form an unlikely alliance, and Naruto's presence could start to change the power dynamics in Esdeath's territory.

One possibility is that Naruto joins Akatsuki to change it from within. He might think he can stop their more evil plans while also learning more about his own powers and the secrets of the ninja world that Akatsuki seems to be involved in.

Well, if Naruto joins Akatsuki in fanfiction, perhaps it's because he's disillusioned with the Hidden Leaf Village for some reason. Maybe he feels betrayed by them. In Akatsuki, he could form unexpected alliances. For example, he might bond with Hidan over their shared brashness in a way, and together they could influence the direction of Akatsuki's actions.

Maybe Naruto joins the Akatsuki with the intention of spying on them for Konoha. He could pretend to be on their side while secretly sending information back to his village. This would add a lot of tension and secrecy to the story as he has to constantly be careful not to be discovered.

Well, it could be about Naruto finding a new group to belong to. Maybe he's lost in a strange world and the horde takes him in. He might bring his ninja skills and unique values to the horde, causing all kinds of changes in their way of life.

In this fanfiction, Naruto could bring his sense of justice to the mafia. He may try to reform it from the inside, facing a lot of resistance from the traditional mafia members who are used to their old ways. His shadow clone jutsu could be used for things like gathering intelligence or creating diversions during mafia operations.

One possibility could be that Naruto goes to Suna to help them with a new threat. Maybe there's a powerful enemy that only Naruto's skills, like his Rasengan and shadow clone jutsu, can deal with. He then starts training some of the Suna ninjas in new techniques, leading to stronger bonds between Konoha and Suna.

One possible plot could be that Naruto goes to the Hidden Rain Village (Ame) seeking refuge or on a diplomatic mission. There, he discovers a new side of the ninja world, with different fighting styles and political intrigues. He might form alliances with some of the local ninjas and help them face a common enemy, perhaps an old foe that is threatening both Konoha and Ame.
