What Are the Most Popular Tropes in Highschool DxD Issei Crossover Fanfiction?

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.

The crossover element itself is a huge trope. Combining the unique worlds of Naruto, Highschool DxD, and the concept of ghouls allows for all kinds of interesting scenarios. Such as when the different magic systems and ninja techniques interact. For instance, a character might try to use a jutsu in the world of Highschool DxD or combine a devil's power with a ghoul's ability.

Another popular plot is Murayama getting involved in Issei's battles. Since Issei is often in the middle of dangerous fights against devils and other supernatural beings, Murayama might decide to jump in and help. This could be because she has a secret ability or just because she cares deeply about Issei. In these fanfictions, their relationship grows stronger as they fight side by side.

One interesting Issei crossover fanfiction could be where he crosses over into the world of 'Fate/stay night'. In this scenario, Issei's devil powers might interact in unique ways with the Servants and magic in the 'Fate' universe. Another could be a crossover with 'Naruto', where Issei has to face the shinobi world with his devil abilities. There are also some crossovers where he goes to the world of 'One Piece' and has to deal with pirates and Devil Fruits while still having his own devilish powers.

The 'Alternate Universe' trope is very much used. For example, an alternate universe where the events of Unlimited Blade Works and Highschool DxD are intertwined from the start. Maybe the Grail War is a regular occurrence in the Highschool DxD world. Another trope is 'Identity Reveal'. A character might be hiding their true identity from one universe while in the other, and when it's revealed, it causes a stir. Also, the 'Forbidden Love' trope can be interesting. If there are rules against a relationship between a character from Unlimited Blade Works and one from Highschool DxD, like a magical or social taboo, it can create a lot of drama and tension in the fanfiction.

Issei himself is obviously very popular as he is the central character. His growth from a perverted high school student to a powerful 'harem king' is a major draw. Rias Gremory is also highly popular. Her beauty, power, and her relationship with Issei make her a favorite in many fanfictions.

One popular alternate protagonist could be Kiba Yuuto. He has his own backstory and is quite popular among fans. In Issei - bashing fanfics, he could take the lead as he is strong, noble, and has his own set of values. Another could be Akeno Himejima. She has a complex personality and powerful abilities. Fans might be interested in seeing her in a more central role without Issei around.

Issei is a very interesting character. His growth throughout the series is something that many fans like to explore further in fanfiction. They can take his character in different directions, whether it's more power - up scenarios or different relationship developments.

The world of Highschool DxD that Issei is a part of is full of magic, demons, and other supernatural elements. Issei's character serves as a great entry point for readers into this world. Fanfiction writers can use his perspective to introduce new elements to the story, or take the existing elements and twist them in unique ways. His character is like a blank canvas in a way, where writers can paint their own versions of the Highschool DxD universe.

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.
