Often, a theme is the breakdown of the Naruto - Sasuke relationship. Since Naruto leaves Konoha, it's a huge shift. And the Sasuke bashing can stem from the idea that Sasuke didn't do enough to support Naruto or keep him in Konoha. Maybe Sasuke is shown as being too prideful or cold - hearted in these fanfics. Another theme could be Naruto's search for a new purpose outside of Konoha, away from Sasuke's shadow.
One possible fanfic could be 'Abandoned Bonds'. In this story, Naruto's departure from Konoha sets off a chain of events where Sasuke is seen in a negative light as he fails to understand Naruto's reasons for leaving. However, it's important to note that Sasuke - bashing can be a divisive concept among fans as Sasuke has his own complex backstory and motives.
This type of fanfiction concept is really out of the ordinary. Naruto's character is built on his values of friendship, loyalty, and his dream of becoming Hokage. Killing Sasuke would mean betraying all of that. However, in a fanfiction, the author might be exploring the 'what - if' scenario. For example, what if Sasuke's actions against Konoha were so heinous that Naruto felt he had no choice? But still, it's a far - fetched and very different view from the original Naruto we know.
Yes, there might be such fanfics out there. In the Naruto fandom, with a large number of fans creating various types of stories, it's possible that some would write a story where Naruto destroys Sasuke in a way that could be seen as Sasuke - bashing. However, these kinds of fanfics may not be in line with the overall spirit of the original work which focuses on their complex relationship and growth.
They're popular because they offer a different view. People like to see alternative takes on the well - known Naruto story. Konoha is always shown as a good place in the original, and these fanfics break that mold.
Perhaps they are forced to leave due to false accusations or being framed for something they didn't do. This could create a situation where they feel they have no choice but to leave Konoha in order to clear their names and also protect the village from the real threats that might be lurking in the shadows.
Well, it could go in many directions. Maybe Naruto starts a quest to find a way to bring peace to the ninja world on his own terms. Or perhaps he has to deal with the consequences of leaving Konoha and tries to prove his intentions were pure.
Well, it could be that Naruto leaves because he realizes that Konoha's ways don't align with his ideals anymore after that intense mission. Or perhaps there are hidden threats that force him to go away for the greater good.
They are often re - imagined as more independent. Without the full influence of Konoha, Naruto might not be as eager to seek approval from the village. Sasuke, too, could be seen as less consumed by his revenge against the village. Instead, they are more focused on each other and their own relationship.
One common theme could be the exploration of an alternate relationship between female Naruto and Sasuke that goes against the traditional narrative in the original series. Another theme might be the criticism of Konoha, perhaps highlighting its flaws through the eyes of the characters. Maybe it also involves a re - imagining of the power dynamics between the two main characters in a more romantic and less traditional way.
