In Highschool DxD fanfiction, a common trope regarding Issei is his growth as a character. He often starts as a pervy and weak character but gradually becomes stronger and more noble. Another aspect is his relationships, like his complex interactions with the various female characters in the series.
One of the things that stands out in Issei - related fanfiction is how his powers are explored differently. Sometimes, authors give him new abilities or enhance his existing ones in unique ways. For example, his Boosted Gear could be modified to have additional functions that are not in the original series. Also, his role in the Devil - Angel - Fallen Angel politics might be expanded, making him a key player in new power struggles.
Often in these fanfictions, Issei's backstory is delved into more deeply. His family life, his early experiences with the supernatural before the start of the main story, and his insecurities are all explored. This helps to flesh out his character even more and makes the reader understand his actions and decisions in the fan - created scenarios better.
A less common but still interesting trope is the 'reversal of roles'. In some fanfictions, Issei might find himself in a world where his devil powers are seen as something different or even feared in a new way. Maybe in a world of pure angels, he is the outcast and has to prove himself not to be an evil entity. This trope allows for a lot of character exploration and development for Issei.
The theme of self - discovery is also common. Issei in many fanfictions is on a journey to find out more about himself, his place in the world, and his true potential. And of course, the theme of the supernatural world and all its elements like magic, different species, and ancient secrets is often a big part of these fanfictions as it was in the original Highschool DxD.
One common trope is the 'rival - turned - lover'. In Highschool DxD, there are often strong female characters who start off as rivals but then develop romantic feelings for each other in yuri fanfictions. Another trope is the 'forbidden love' aspect, considering the complex relationships and power dynamics in the original series. This adds an extra layer of tension and drama to the yuri relationships.
Romance is also a big theme. Just like in the original Highschool DxD, his son usually has his own love interests. These relationships can be complicated by his status as Issei's son. Sometimes, potential partners are attracted to him because of his family name, and he has to figure out if their feelings are genuine.
Power - up themes are also quite common. Issei often gets new powers or abilities, and Rias may play a role in that. For example, in some fanfictions, Rias helps Issei to master a new form of his Sacred Gear. This not only strengthens Issei but also deepens their bond as they train together. Another aspect is the exploration of the supernatural world in the context of their relationship. Since Highschool DxD has a rich supernatural setting, fanfictions may expand on this, like how Issei and Rias face new threats from the underworld or other dimensions together, which further cements their relationship and showcases their individual growth.
Another theme is adventure. Since Highschool DxD has a lot of action and supernatural elements, fanfictions might have Issei and Akeno going on adventures together, facing powerful enemies and overcoming challenges as a team. They could be fighting against other devils, angels or fallen angels in these stories. And often, these adventures also contribute to the growth of their relationship.
Well, often in Highschool DxD Issei bashing fanfiction, a common theme is power redistribution. Since Issei is a central figure in the original in terms of power - up and his role in battles, these fanfictions might shift the focus to other characters getting stronger or more important in different ways. It could also be about changing the overall tone of the story. Instead of Issei's more comical and pervy attitude driving parts of the plot, the fanfiction might have a more serious or different comical approach by removing or reducing his presence.
One common theme is power escalation. Since Issei is OP in these fanfictions, the story often focuses on how he continues to gain and control his ever - increasing power. Another theme is harem - related, as in the original Highschool DxD, Issei has a harem. In the fanfictions, his OP status might attract even more characters to his harem, and the dynamics within the harem change because of his new power level.
Yes, there might be. There are a vast number of fanfictions out there for various combinations of popular culture elements. Since Highschool DxD has a large fan base and Godzilla is an iconic figure, it's not unlikely that some creative fans have combined the two in a fanfiction. You can try searching on popular fanfiction websites to find such works.
There could be. Fanfiction writers are known for their wild and creative crossovers. Given the popularity of Highschool DxD and the unique concept of Guyver, it's entirely possible that an Issei - Guyver fanfiction exists. You might want to check popular fanfiction websites like Archive of Our Own or FanFiction.net. Just search for relevant keywords like 'Highschool DxD Issei Guyver' and see if any relevant stories pop up.
