One reason could be the pressure on Boruto. In fanfiction, if Boruto fails to meet the high expectations set by Naruto's legacy, Naruto might show disappointment which could be misinterpreted as hatred. Also, there could be external forces in the fanfic world, like an enemy influencing their relationship, making Naruto seem like he hates Boruto.
It could be that the fanfiction simply doesn't meet Boruto's standards for what the Naruto universe should be like. He has grown up in that world and has his own ideas about how things should be. Fanfiction can be very hit - or - miss in terms of quality and faithfulness to the source material. If it's of poor quality or changes things too much, Boruto might hate it.
It could lead to a shift in the types of fanfiction created. Fans might start to be more cautious about what they write to avoid the idea of Boruto hating it. This could result in less creative and more restricted fanfiction, as people are trying to adhere to what they think Boruto would approve of. On the other hand, some fans might rebel and create even more out - there fanfiction just to make a point.
One great 'Boruto and Naruto fanfic' is 'A New Generation's Bond'. It beautifully shows the relationship between Boruto and Naruto as they face new threats together. The characterizations are on point and the story has a good flow.
Boruto's reaction would be complex. He'd be heartbroken, for sure. He might start to question his own worth and purpose. But over time, he'd realize that he has to carry on Naruto's legacy. He'd become more serious and focused. He'd also become more empathetic towards others, understanding the weight of sacrifice. He might even start to study Naruto's techniques and leadership style more closely, trying to emulate the things that made Naruto such a great Hokage and hero.
Well, Naruto could show Boruto his Sage Mode power. Sage Mode gives Naruto enhanced strength, speed, and the ability to sense chakra more acutely. It's a very powerful form that Naruto has mastered over time. By revealing it to Boruto, he might be teaching Boruto about the different levels of power and the hard work required to achieve such power.
A fanfic that stands out is 'Boruto's Path to Hokage'. It imagines Boruto's journey to becoming the Hokage in a very unique way. It includes elements from both Naruto's and Boruto's eras, like new villains inspired by the past ones and the development of new jutsu. The story also focuses on Boruto's relationships with his family and friends, which adds a lot of depth.
A Boruto time adventure in a Naruto fanfic can be really interesting. It might start with Boruto finding some sort of time - traveling device or jutsu. Once he's in Naruto's time, he may face challenges not just in the battles but also in fitting in. He could interact with characters like Sasuke, Sakura, and Kakashi. His presence might also cause some changes in the timeline, leading to unexpected events that both he and the original characters have to deal with.
In some fanfics, Boruto might be depicted as hating Naruto because of the lack of attention he gets from his father. Naruto is often busy with Hokage duties, leaving Boruto feeling neglected.
In some fanfics, the idea of Naruto hating Hinata might be a plot device to create drama. Maybe the writer wants to explore a different kind of relationship dynamic than the canon one. It could also be that the writer has a unique interpretation of the characters' personalities and how they might clash in certain situations.
