A really cool plot could be that in a strange turn of events, Boruto and Sasuke end up in an alternate dimension. They must find their way back while facing the challenges of that dimension, which has different rules and powerful beings. This would test their adaptability and their relationship.
One interesting plot could be Sasuke taking Boruto on a special training journey across different hidden villages. This would not only strengthen Boruto's skills but also give them a chance to bond like master and apprentice.
Perhaps a plot where Boruto and Sasuke are on a mission to stop a new and powerful enemy that threatens the entire ninja world. They have to combine their unique abilities, with Boruto's new-age techniques and Sasuke's experience and Sharingan powers.
Naruto is likely to be popular too. Even though it's a Boruto x Sasuke fanfic, Naruto's relationship with both of them is so important. He could play a role in supporting them from the sidelines or even getting involved in a crucial part of the story.
Well, a cool plotline could be Boruto having to deal with the combined enemies of his father and Sasuke. Enemies from Naruto's past might target Boruto to get revenge on Naruto, and at the same time, there could be remnants of Sasuke's old foes as well. Also, in the fanfic, it would be interesting to see how Boruto's training is different. Maybe he has both Naruto and Sasuke as his mentors, and they constantly bicker about the best training methods, which adds a bit of humor to the story.
Another idea is a 'what - if' scenario. For example, what if Boruto was raised in a world where Naruto had failed to become Hokage? This could lead to a very different Boruto, perhaps more cynical or desperate to change the world on his own. The fanfic could explore how he would grow up and try to fix the situation his father couldn't.
In Boruto x Naruto fanfic, often the character development can be quite fascinating. For example, we could see how Boruto deals with the legacy of his father, Naruto. Writers might create scenarios where Boruto has to face challenges that test his understanding of his father's ideals and his own path. It also allows for a deeper look into Naruto's role as a father and how he imparts his values to Boruto.
One interesting plot could be that Naruto and female Sasuke team up in a different way than in the original story. Maybe they go on a journey to discover a new chakra source together. They face challenges that test their bond and skills, and along the way, they start to see each other in a new light.
Some fanfics have the OC being from a different clan that has a long - standing feud with the Uchiha. But Sasuke and the OC break the cycle of hatred. They have to overcome the objections of their respective clans while trying to understand their feelings for each other. It's a story of love defying old grudges.
A story could be set in a future where Boruto has become a great ninja and Himawari is training hard. Boruto takes on the role of a mentor to Himawari for a while. They embark on a mission together to stop a powerful enemy who is threatening the peace of the ninja world. Along the way, they learn more about each other's strengths and weaknesses and their relationship evolves.
A plot where Naruto and Boruto have to team up to fight a new, powerful enemy that neither could defeat alone. This would allow for some great father - son bonding moments and also show how their skills complement each other. For example, Naruto's brute strength combined with Boruto's unique ninja techniques. It could also explore how Naruto imparts his wisdom about the ninja way to Boruto during the battle.
Perhaps a plot where Sakura discovers a long - hidden secret about Sasuke's past during their travels together in the Naruto Gaiden fanfic. This could lead to a deeper understanding between them and some emotional moments.
One interesting plot could be that Naruto and Sasuke travel back to their childhood days. They use their knowledge of the future to prevent certain tragedies, like the Uchiha massacre. They might also try to change how they first interacted, making their bond stronger from the start.
