I'm not entirely sure as I haven't read it specifically. But generally, a fanfiction related to 'DxD' (presumably 'High School DxD') that focuses on something before the events in the main series could be about the backstories of the characters, perhaps how the world of DxD was set up before the main story's timeline started, like the relationships between different factions before the start of the main narrative.
Since it's a fanfiction about 'the one before DxD', it could be centered around the predecessors of the main characters. For example, if the main story has a powerful devil character, this fanfiction might tell the story of an ancestor of that devil. It could also show how the political or social structure of the supernatural world in 'DxD' was formed in the time before the main story took place. This might include how different races interacted, treaties were made or broken, and how power dynamics were established.
I don't know for sure since I haven't read it. But it could feature the ancestors or predecessors of the main characters from 'High School DxD'. For example, if Issei is a main character in the original, it might have someone related to his family line in the past.
If 'dxd' is indeed related to 'High School DxD', it has a world full of demons, angels, and other supernatural beings. Fanfiction often takes the existing setting and expands on it. 'Si' fanfiction might introduce a new character, usually the self - inserted one, who could interact with the known characters like Issei Hyoudou. This could lead to various plot twists, such as changing the power dynamics, or exploring different romantic relationships within the 'dxd' world.
DxD fanfiction is often about the world of 'High School DxD'. It can include various stories that expand on the original plot, such as different relationships between the characters. Maybe there are new adventures for Issei and his friends, or alternative scenarios for the battles they face.
In 'naruto reborn dxd fanfiction', it may explore how Naruto's character develops in a completely new and different environment. Since the DxD world has a different power system and different kinds of relationships, Naruto would have to face new challenges. He might have to learn about the Rating Games in DxD and participate in them using his ninja strategies. Also, his values from the Naruto world like friendship and perseverance would be put to the test in this new world filled with different temptations and dangers.
I'm not entirely sure specifically as it could be a very niche or even a made - up concept within a particular fan community. It might involve some sort of story in the 'High School DxD' universe where there's a concept of 'annihilation' and a'maker' which could be a character or a force that causes annihilation. But without more context, it's hard to say for sure.
In the case of 'dxd rias bashing fanfiction', it could be centered around different aspects. It might be that the author has a different vision for the 'dxd' world and Rias doesn't fit into that vision as she is in the original. So they create a fanfiction to bash her character. It could also be due to personal preference of the author. They might prefer other characters over Rias and use the fanfiction as a platform to show why they think Rias has negative qualities. Another possibility is that they want to explore how the story would change if Rias was not the 'perfect' character as she seems in the original, so they write a bashing fanfiction to break her down and see what new stories can emerge.
Since the term contains 'adult', it's likely that this type of fanfiction might involve themes not suitable for all audiences. It could be that fans are exploring more mature or risqué storylines within the 'DxD' universe. But this kind of content is often not in line with ethical or family - friendly standards.
It could be a wide range of things. Since 'dxd' likely refers to High School DxD, the 'dragon fanfiction' part means that the stories in this fanfiction probably focus on the dragon characters or elements in the series. It might include things like a dragon's origin story in the DxD universe, or how a character interacts with a dragon in a new and unique way.
One idea could be a crossover where the Straw Hats end up in the DxD world and have to deal with the Devils and Angels there. They might use their unique abilities like Luffy's stretching powers to face off against supernatural foes.
Yes, there might be. You can start by checking some popular fanfiction websites like FanFiction.net or Archive of Our Own. They often have a wide range of fan - made translations, but the availability of a complete English translation of a One Piece DxD fanfiction depends on how popular it is among the fan translation community.
