From the Tsukune side, Tsukune would be there as the character being bashed. His friends from his own story might also make an appearance, but mainly to be overshadowed by the Naruto characters. For example, Moka could be in it, but the focus would be on how Naruto characters are better in various aspects compared to her and Tsukune.
One common theme could be power dynamics. Maybe in these fanfics, characters from Naruto are shown to have more power compared to Tsukune. For example, Naruto's ninja abilities might overshadow Tsukune's skills.
Not really. Most Naruto fans love the original characters and their relationships. Bashing a character like Rin might not sit well with a large portion of the fan base. So, these types of fanfics are likely not as popular as those that stay true to the positive aspects of the Naruto characters.
In a way, it is ethical. Writing a bashing Naruto fanfic can be seen as a critique. Just like in real - life literature, authors can analyze and dissect characters. However, the key is to not cross the line into harassment or excessive negativity. You have the right to your opinion about the character, but you should also be prepared for others who may not agree with your bashing.
Another theme might be his relationships. Maybe in these bashing fanfictions, his relationships with the female characters are misconstrued or made to seem one - sided in a negative way. For example, his bond with Moka could be portrayed as him being clingy or unworthy. Also, his attempts to fit into the monster school could be shown as him being incompetent rather than the plucky underdog he is in the original story.
In the Naruto fan community, 'naruto bashing fanfic' is not very popular. The majority of fans have a positive view of Naruto and are attracted to the story because of his journey from an outcast to a hero. Fanfics that bash him can be seen as a bit of an oddity. However, there could be a niche group of fans who, for various reasons like wanting to explore different power dynamics or having a different view on character development, might be interested in such fanfics. But compared to fanfics that are more in line with the positive view of Naruto, they are definitely in the minority.
There are 'naruto deception sasuke bashing fanfic' because the Naruto universe has a lot of room for different interpretations. Fans who are more fond of Naruto might create stories where Sasuke is deceived to show Naruto in a more favorable position. Also, it could be a way to explore different moral and ethical situations within the Naruto world. For instance, if Sasuke is deceived into doing something bad, it can start a discussion about whether he is truly at fault or if the deceiver is the real villain. This adds depth to the fanfic community's exploration of the Naruto world.
I'm not really sure of specific 'rosario vampire tsukune bashing fanfiction' titles off - hand. You could try searching on popular fanfiction websites like Fanfiction.net or Archive of Our Own and use those keywords in the search bar.
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.
One reason is the difference in interpretation. Some fans have a very set idea of what Naruto should be, and when a fanfic goes against that, they bash it.
