There could be. Fanfiction often takes creative liberties with the original characters and storylines. While the Naruto series itself doesn't have this plotline for Kiba, in the world of fanfiction, where different interpretations and ideas are explored, it's possible that some writers have created stories where Kiba cheats. But it's important to note that not all fanfictions are of the same standard, and some might not be well - written or in line with the general spirit of the Naruto universe.
I'm not sure if there is a particularly popular 'hinata cheats on naruto with kiba fanfiction'. Fanfiction varies greatly in popularity and quality. Some might find such a plotline unappealing as it goes against the original relationships in the Naruto series. However, in the vast world of fanfiction, there could be some out there, but it's not something that is mainstream or widely known to be super popular.
Naruto would be extremely hurt. He loves Hinata deeply and to find out she cheated with Kiba would be a huge blow to him. He might go into a state of shock and disbelief at first.
Most fanfics with such a premise are not likely to have a positive message as cheating is an unethical behavior. However, some might use it as a starting point to explore complex relationships and redemption arcs, but that's rare.
I'm not sure of specific titles off - hand. But generally, such fanfictions might involve Kiba cheating on a relationship with another character from the Naruto world, perhaps someone like Hinata or another female character. It could be due to misunderstandings, or the writer might be exploring a darker side of Kiba's character.
In a fanfic like this, it might start with Hinata feeling neglected by Naruto due to his busy Hokage duties. Kiba, being an old friend, is always around to offer support. But this is a very uncharacteristic plot as Hinata is deeply in love with Naruto in the original series. It would likely cause a lot of drama and conflict within the Konoha community.
It's a rather strange concept. In the original Naruto story, Hinata has deep feelings for Naruto. The idea of her cheating with Kiba seems to go against the established character traits. It might be an interesting and controversial take in fanfiction, but it's not something that would be expected based on the canon.
One reason could be for the sake of creating drama. Fanfic writers often like to explore extreme scenarios that deviate from the original story to generate intense emotions and reactions from readers.
There's also 'The Female Ninja and Kiba'. In this fanfiction, a female ninja with unique abilities teams up with Kiba. It delves into how their different personalities complement each other. For example, her calmness balances out Kiba's sometimes over - enthusiastic nature, making for an interesting dynamic.
There are various scenarios that could play out in such a fanfiction. Maybe Naruto was injured during a mission and Kiba stumbles upon him in the forest. Kiba would then likely try to help Naruto, either by getting medical help or using his own skills if he has some knowledge of healing. This could lead to a deeper bond between them as Kiba shows his concern and Naruto is grateful for the assistance.
