What are some interesting concepts in highschool dxd fanfic?

In some Highschool DxD SI Fanfiction, the self - insert might come from a different world or time period. This brings in elements of cultural shock and different knowledge systems. They could introduce new technologies or fighting styles to the world of Highschool DxD, which can lead to very creative and engaging storylines.

One interesting concept could be the combination of Pokemon powers with the abilities of the characters in Highschool DxD. For example, a character might be able to use a Pikachu's electricity - based attacks in combat situations within the Highschool DxD universe. Another concept could be the idea of Pokemon existing in the same world as the devils, angels, and fallen angels in Highschool DxD. This could lead to some really unique interactions, like a Pokemon being tamed by a devil and used as a sort of familiar or ally in battles against other factions.

Another concept could be the exploration of different power systems. Hellsing has its own set of rules regarding vampire powers, holy weapons, etc., while Highschool DxD has the Rating Game system and the various devil powers. Fanfiction might play around with how these power systems interact, like if a character from Hellsing were to participate in a Rating Game or how a devil from Highschool DxD would fare against a Hellsing vampire.

One interesting concept could be the exploration of different character relationships in a more subdued or 'silent' way. For example, how the main character might form unexpected friendships without the typical high - energy drama. Another could be the re - imagining of the story's settings in a more peaceful or reflective manner.

One interesting concept could be a crossover where the characters from Highschool DxD encounter Slenderman. Maybe the devils in Highschool DxD are intrigued by Slenderman's otherworldly and spooky nature. They might try to either recruit him or fight him, depending on their motives.

One interesting concept could be the crossover of the Highschool DxD world with the eerie and mysterious Slender Man.

Maybe the devils in Highschool DxD would try to make a deal with the Slender Man or fight against him to protect their territory.

Another concept is the exploration of different relationships. In highschool dxd system fanfiction, characters might form new alliances or romances that weren't as prominent in the official story. This can lead to some really engaging character development.

In Gilgamesh Highschool DxD fanfiction, there might be concepts like Gilgamesh forming alliances or rivalries with the devils, angels, and fallen angels in the Highschool DxD world.
