One possible plotline could be that Naruto is transported to the Highschool DxD world and immediately notices Rias's overbearing attitude. He decides to oppose her and starts to gather allies among the other students and characters who are also fed up with her ways. As a result, a power struggle ensues between Naruto and Rias.
Well, it could involve Naruto characters being thrown into the Highschool DxD universe and having some sort of conflict with Rias. Maybe Naruto's skills and values clash with Rias's actions or leadership in the story. For example, Naruto might see her as too power - hungry or not treating her underlings fairly.
I'm not sure specifically about 'naruto rias bashing fanfiction' being popular. There are so many fanfictions out there that it's hard to single out ones that are bashing a particular character as being popular. However, in general, if a fan has a strong opinion about a character like Rias, they might write a story that gets some attention within their niche community, but it may not be widely known outside of that.
Well, 'naruto rias bashing fanfiction' could be stories where the writer doesn't like Rias for some reason and decides to create a narrative that shows her in a bad light. It might be that the writer thinks Rias' actions or personality traits don't fit well with their view of how a character should be. And when combined with Naruto, perhaps they are using elements from Naruto's world to further emphasize the flaws in Rias as they see them. Maybe they are comparing her unfavorably to Naruto's values or the way Naruto's world works.
In such a fanfiction, it could be that Issei is bashed because he represents a different kind of hero compared to what Naruto stands for. Naruto is all about self - sacrifice and believing in others no matter what, while Issei is more about his own desires and power - seeking in a way. So when these two worlds collide in the fanfic, Issei might be made to look bad in comparison. Maybe the story has Naruto characters like Sasuke or Kakashi giving Issei a hard time because they don't approve of his behavior.
Some people might write such bashing fanfiction because they prefer other characters or storylines over Naruto, Rias, and Issei. Maybe they want to create a different narrative where these characters don't overshadow their favorites. It could also be a form of creative expression to explore how a story would be different without them.
In this type of fanfiction, the author might be trying to create a new narrative by bashing Kiba. It could be that they have a particular vision for how the Naruto and High School DxD worlds blend together. Maybe they think Kiba's character doesn't fit well in their idea of the crossover, so they use him as a sort of 'villain' or an obstacle for the other characters to overcome. This can add drama and a new layer of storytelling to the fan - made universe.
One common plotline could be Naruto being extremely powerful, like a god, and outshining Rias in various challenges or battles. For example, in a tournament setting where Naruto's unique abilities completely overshadow Rias' powers. Another could be Naruto using his godlike status to reform or change the world in which Rias exists, causing her to be in a position where she has to adapt or face difficulties.
For the Naruto fandom, bashing fanfiction could potentially turn some fans away from the overall fanfiction community if they feel that their beloved character is being unfairly targeted. In the case of Rias and Issei's fandoms from High School DxD, it could create a stir as well. Some fans might engage in debates with the writers of the bashing fanfiction, trying to defend the characters. This can lead to both positive and negative interactions within the fandoms. On one hand, it can spark discussions about the characters' qualities, but on the other, it can also lead to a hostile environment if not handled properly.
One possible idea for this fanfiction could be Naruto being transported to the world of High School DxD. He might end up attending the same school as Rias. Given Naruto's strong sense of justice and his combat skills, he could quickly become involved in the supernatural battles and power struggles in that world. He might also form an interesting relationship with Rias, perhaps starting as friends and gradually developing into something more as they face various challenges together.
