Maybe in the fanfiction, Naruto and Sasuke enter a tournament together. They support each other throughout the battles, with Sasuke using his sharingan to analyze opponents' moves and Naruto using his shadow clones to create diversions. Their combined efforts and the way they cheer each other on is like real brothers.
A great plot could be that Naruto and Sasuke discover they have a long - lost family connection. They start to investigate it together, facing many challenges along the way. During this journey, they bicker like brothers sometimes, but also show great loyalty and protectiveness towards each other. For example, when one is injured, the other goes into a rage to defend him.
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.
A really interesting plot could be that Naruto and Sasuke, as brothers, are on a quest to find the origin of the Sharingan. Along the way, they meet different characters who have different views on the Sharingan. Some see it as a curse, while others see it as a gift. This journey makes them question their own beliefs about power and family. As they get closer to the truth, they also face challenges from those who want to keep the origin of the Sharingan a secret.
One idea could be that they discover they are blood brothers during a dangerous mission. This revelation then changes their entire dynamic and they start to fight side - by - side with a new level of unity. Another could be that there is a hidden prophecy about the two of them as blood brothers saving the ninja world in a unique way that no one else could.
One plot idea could be that they discover their relation early on. Naruto, being his usual positive self, tries to get closer to Sasuke right away. Sasuke, on the other hand, is initially in denial but gradually warms up as they start to train together more often. They could team up against stronger enemies earlier in the story, using their combined skills and the new - found bond of being half - brothers to their advantage.
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.
Perhaps in the fanfiction, as brothers, they have to face a common enemy that is specifically targeting their family line. This would make them rely on each other's unique abilities. Naruto's never - give - up attitude combined with Neji's precision could lead to some epic battles.
Well, a great plot could be that Kakashi, being Naruto's brother, decides to train Naruto in some super - secret jutsu that only their family knew. This would give Naruto an edge in battles and also strengthen their bond. Or perhaps they get into an argument over their different views on the village's future, but in the end, their brotherly love prevails. It could also be interesting if they both have to protect a precious family heirloom from villains who want to use it for evil.
One plot idea could be that Naruto uses his determination and new jutsu to impress Sasuke. He shows Sasuke how much he has grown and tries to convince him to come back to Konoha through his strength and loyalty. Another could be Naruto sharing his dreams of a future where they are friends again and they can protect the village together, appealing to Sasuke's sense of belonging.
One interesting plot could be a mission where Naruto, Hinata and Sasuke have to work together. During the mission, Hinata's shy nature starts to break as she has to communicate clearly with both Naruto and Sasuke. Maybe there's a powerful enemy that only their combined skills can defeat. Naruto uses his Rasengan, Sasuke his Chidori, and Hinata her Byakugan - based techniques in a coordinated attack.
Another idea is that baby Sasuke and Naruto are found together by a third party, like a wandering ninja who decides to train them both from a very young age. This would create a different dynamic as they grow up together with a unique set of skills taught by this unknown mentor. They would probably have a stronger bond from the start compared to in the original story.
