What are some interesting plot ideas for Naruto and Sasuke as blood brothers in fanfiction?

One idea could be that they grow up with a new sense of family loyalty. They might support each other in ways different from the original story. For example, Sasuke could be more open about his feelings because he has Naruto as a true brother. Another plot could be them facing challenges together that are specifically related to their adopted family status, like dealing with the expectations of their new family or protecting their new family from threats.

One idea could be exploring the backstories of the characters more deeply. Maybe delving into their childhoods and how those experiences shaped them into the people they are in the story. Another could be creating an alternate universe where the main characters have different occupations or abilities.

One plot idea could be that they discover their brotherhood early on and train together more closely. They might combine their unique abilities, like Naruto's Rasengan and Sasuke's Chidori, to create new and powerful jutsus. This could change the whole dynamic of the story, with them facing challenges as a united front instead of rivals.

One idea could be that the Kurama brothers have a secret mission to protect Naruto from an ancient evil that only they know about. They use their unique powers and knowledge to train Naruto in ways that no one else can.

Perhaps they could start off not knowing they are brothers. Naruto is in his ninja world and Goku is in his. Then, a strange rift in the dimensions brings them together. They realize their connection when they notice similar powers or markings. After that, they train together and combine their unique skills, like Naruto's shadow clones with Goku's ki attacks, to face challenges in both worlds.

One idea could be that Naruto and Sasuke are transported to the DxD world and they have to learn the new rules and powers there. They might team up with some of the DxD characters to face a common enemy.

One idea could be a fanfiction where Naruto and Sasuke have to team up again to face a new threat from an ancient evil that has been awakened. They have to put aside their past differences completely and combine their powers in a new way. For example, Naruto could use his Sage Mode along with Sasuke's Rinnegan to perform a super - powerful jutsu.

Well, a cool plot could be Fem Naruto and Sasuke are both entered into a ninja tournament. They start off as rivals but as the tournament progresses, they start to respect each other's skills more. And perhaps there's a mystery behind the tournament that they end up uncovering together. Or maybe Fem Naruto has a special power that only Sasuke can help her control, and in the process of training together, they form a deep bond. Another one is that they are both transported to a modern world and have to adapt while still relying on their ninja skills, and during this time, their relationship evolves in unexpected ways.

One plot idea could be that Naruto and Sasuke discover a new power related to the Rinnegan that can only be accessed when they combine their chakra. Another could be a time - travel plot where they go back in time to prevent the creation of the Rinnegan in the wrong hands. Maybe they have to face an enemy who has a corrupted version of the Rinnegan powers and they must use their own understanding of the power to defeat them.

One idea could be Naruto and Sasuke teaming up to face a new, powerful and ancient threat that even the combined might of the Hidden Villages can't handle easily. They have to use their unique skills and the bond they've reforged as Hokage and his equal.
