The villagers would likely be in shock. Naruto is a beloved figure, but killing his own son would be a very controversial act. Some might turn against Naruto, believing he has gone too far. Others might understand his reasons if they knew the full story, but still struggle with the morality of it.
One idea could be a story where Kabuto, after his redemption arc, teams up with Naruto on a special mission. They could face an unknown enemy that requires both their skills. For example, an ancient evil that has knowledge of both medical ninjutsu (which Kabuto is good at) and Naruto's powerful chakra.
The Akatsuki as a whole could be the main antagonist. They might target Naruto as usual, but now with Kabuto on Naruto's side, they have to deal with both of them. The Akatsuki's various members with their unique abilities would pose a great challenge for Kabuto and Naruto to overcome.
One great 'Naruto x Ninja Gaiden' fanfiction is 'The Ninja Alliance'. It combines the unique ninja skills from both universes in an exciting way. The story follows Naruto as he teams up with Ryu Hayabusa to face a new, powerful enemy that threatens both their worlds. The fight scenes are well - written, making it a thrilling read.
To develop Fem Kabuto's character, give her a personal goal that is separate from Orochimaru's. In the fanfiction, she might strive to find a cure for a certain ninja - world disease using her medical knowledge. This not only shows her as more than just a sidekick to Orochimaru but also gives her a positive and independent identity. As she pursues this goal, she can grow and change, and her interactions with Naruto can be shaped by this new - found purpose.
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.
In the 'kabuto sad story', Kabuto could be anyone really. He could be a character from a small - town folktale, where he was known for his kindness but was wronged by the people in the town. Maybe he was framed for a crime he didn't commit, and as a result, he lost his reputation and had to live in isolation. This would be a very sad situation for him indeed.
One popular Boruto x Naruto yaoi time travel fanfic is 'A New Chance'. It takes Naruto back in time and explores his relationship with Boruto in a different timeline. The story has great character development and an interesting plot that keeps you hooked.
I've also heard good things about 'Naruto and Boruto: A New Adventure'. In this fanfic, they go on an adventure outside of the Hidden Leaf village to face a new and powerful enemy. The story does a great job of highlighting both Naruto's experience and Boruto's fresh perspective, and how they complement each other during the battle.
A good fanfic would stay true to the characters' personalities. In the case of Naruto, he should be shown as the determined and somewhat goofy hero. Hinata should be her shy yet strong - willed self. For example, if Naruto is in a tough situation, he would never give up easily. And Hinata, even when she's scared, would find the courage within her.
