It could also be due to a rift in their relationship over Boruto's ninja path. If Boruto decides to take a very different and unorthodox approach to being a ninja that Naruto doesn't approve of, such as using forbidden jutsu without proper understanding, Naruto might disown him in the fanfiction.
The disowning could also have an impact on the other characters. For instance, Hinata might be caught in the middle, trying to reconcile Naruto and Boruto. The other villagers might have different opinions about the situation. Some might side with Naruto, believing he had a good reason, while others might think Naruto is being too harsh on Boruto. This can add layers of complexity to the fanfiction's plot.
Naruto might be extremely heartbroken. He has always looked up to his mother, and being disowned by her would be a huge blow. He could become withdrawn and start to question his own worth.
Physically, Naruto can use his Rasengan or other powerful jutsus to fend off enemies attacking Boruto. His combat skills are top - notch, and he won't hesitate to engage in battle to keep Boruto safe.
It could be due to a perceived betrayal. Suppose Naruto discovers some dark secrets within his family that he can't overlook. In his 'godlike' state, he might be more morally rigid and thus decides to disown them. For instance, if he finds out that his family was involved in some unethical ninja practices in the past, he would feel compelled to distance himself.
It could also be due to some external influence. Perhaps an enemy used some kind of mind - control or manipulation on Kushina. They made her think that Naruto was a threat, so she decided to disown him. In the Naruto universe, there are many powerful villains who could potentially do this kind of thing.
One great 'Boruto and Naruto Fanfiction' is 'A New Era of Shinobi'. It really delves into how Boruto and Naruto's relationship could evolve further, with Boruto learning new jutsus from his father in a more in - depth way than in the canon story. It also explores the political unrest in the shinobi world that wasn't fully covered in the anime or manga.
Not really. Naruto has always been interested in the stories of the ninja world. Fanfiction is just another form of those stories, just more fan - created. So it's not that strange for him to be curious about what fans think about his son's story.
It's not that strange. Naruto is a curious person. Since Boruto is his son, he would be curious about how others imagine Boruto's story in fanfiction. He might even find some new perspectives on his son's character and the ninja world that Boruto is growing up in. Also, Naruto has always been open - minded, so the idea of exploring fan - created stories about his family wouldn't be too out of the ordinary for him.
I don't think there would be a lot of fanfiction like that. Hinata has always been loyal to Naruto. In the Naruto universe, their relationship is based on a lot of development and mutual understanding. So it's hard to imagine a scenario where Hinata would cheat on Naruto with Boruto in a legitimate fanfiction.
