One interesting story could be the ones where the characters from Dragon Ball Z end up in the High School DxD universe and have to adapt to its rules. For example, Goku trying to understand the whole devil - angel - human dynamic in the High School DxD world would be quite fascinating.
Stories that involve power - level crossovers can be really cool. Imagine Vegeta competing in the Rating Games in High School DxD. His Saiyan pride and combat skills would make for an exciting read. Also, fanfictions that explore the relationships between the characters of both series, like how Gohan and Issei might interact as classmates or allies, are often very engaging.
You can try some popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). They usually have a large collection of fanfictions including those related to Dragon Ball Z and High School DxD.
One possible plot could be that the characters from Dragon Ball Z end up in the High School DxD world and have to deal with the different power dynamics and social hierarchies there. For example, Goku could be intrigued by the way the devils and angels in High School DxD have their own unique powers and politics. He might try to learn from them while also showing off his Saiyan strength.
A possible storyline is the characters forming a high school club related to martial arts or self - defense. They could teach other students and at the same time learn more about human relationships and teamwork. This would be a great way to see how they adapt to normal high school life while still having their unique powers and abilities.
One interesting plot could be Gohan trying to balance his Saiyan powers with high school life. For example, he might accidentally use his super strength during gym class and have to cover it up.
Another idea is a fusion of the power systems. Maybe in the fanfiction, the Sacred Gears from Highschool DxD could be enhanced by the Dragon Balls. The Dragon Balls' wishes could be used to unlock new forms or powers in the Sacred Gears. This would create a whole new level of power - ups for the characters in Highschool DxD.
Yes, there are many. You can find them on various fanfiction websites. Some might focus on crossovers between the two universes, like having characters from Dragon Ball attend the high school in DxD. Others could explore unique power combinations or relationships between the characters from both series.
A third storyline could be about the high school students discovering the Dragon Balls. They might start off thinking they're just some cool artifacts, not realizing their true power. As they start to figure it out, they could get into all sorts of adventures, with the Z - fighters having to step in to protect them from those who would misuse the Dragon Balls.
Goku would be really interesting. His pure - hearted and naive nature would contrast greatly with the more complex and often morally ambiguous characters in High School DxD. He would see the battles and power struggles in a different light, probably just wanting to test his strength and have a good fight without getting too involved in the politics.
