The original Highschool DxD series focuses mainly on the story of the main character's journey in the supernatural world, his growth in power, and his relationships in a more general sense. However, the smut fanfiction often delves deeper into the sexual aspects of the relationships, which are not as prominently featured in the original.
The SI Fanfiction often explores different relationships. In the original Highschool DxD, the relationships are mainly focused on the main characters' growth and their interactions within the set framework. However, in SI Fanfiction, the self - insert can create new love interests or different kinds of friendships that weren't there before. This can give a whole new perspective on the world of Highschool DxD.
The tone can also be different. The original Highschool DxD has elements of action, comedy, and fan service. The futanari fanfiction might add a more complex layer of themes like identity exploration and acceptance. This is because the futanari characters may face different challenges compared to the regular characters in the original series.
It may differ in terms of plot. The original series has its own set storyline, but the fanfiction can take a completely different turn. For instance, in 'A Devil's Heaven' fanfic, the focus could be on a different group of devils or a new threat to the devil world that wasn't in the original.
In a prematurely written fanfiction about Issei, the story might skip over some of the build - up that makes the original so engaging. His relationships with his friends and the other characters could be rushed. Instead of gradually getting to know the members of the Occult Research Club, he might be thrown into deep, meaningful relationships right away. Also, his battles and challenges might come before he's had a chance to fully train, making his victories or defeats seem less earned compared to the original.
In the original Naruto series, there are no elements from High School DxD. But in this fanfic, Naruto has 12 wings which is a completely new concept. Also, the power scale is different. In the Naruto world, the power is mainly based on chakra, while in this fanfic, with the addition of DxD elements, there are new types of powers like devil powers, angel powers etc. The characters' relationships also change. Naruto might interact with characters like Rias or Issei in ways that are not possible in the original Naruto series.
Well, in some fanfictions, the female Vali can be more in touch with her emotions. The original Vali is often portrayed as a bit more stoic and focused on power. As a female, she might show more vulnerability, while still maintaining her strong and competitive side.
The fanfiction often has the freedom to explore different scenarios. While the original Highschool of the Dead has its own narrative arc, the fanfiction can take it in various directions. It might explore what would happen if a certain character made a different decision during a zombie encounter. Or it could add elements like time - traveling or supernatural powers in the context of the zombie - filled high school, which are not part of the original work.
In fanfiction, the differences can be even more pronounced. A fanfic might exaggerate the serious and brooding nature of a Persona character when they are put into the more flamboyant and action - packed world of Highschool DxD. Or it could show how a Highschool DxD character's brashness clashes with the more methodical and calculated approach of a Persona character. For example, if a Persona character is trying to strategize in a battle, a Highschool DxD character might just rush in, creating an interesting dynamic.
In 'the other original vampire diaries fanfiction', there could be a change in the power balance among the characters. In the original series, there were certain power hierarchies, but the fanfiction might disrupt that. Maybe a weaker character becomes stronger in a unique way. The fanfiction might also have different themes. The original series had themes like love, loss, and power struggles. The fanfiction could introduce new themes such as redemption on a larger scale or the exploration of a different kind of magic. Moreover, the fanfiction can give more freedom to minor characters. They can have more significant roles and storylines that were not given much attention in the original show.
One popular theme could be the relationships between the characters. For example, exploring the romantic and sometimes more intense relationships between the main character and the various female characters in the series. Another theme might be the power dynamics within those relationships, as there are different levels of power among the characters in Highschool DxD.
