One common theme is power comparison. Since 'The God of High School' has a unique power system, when it crosses over with other series, fans like to see how the powers stack up. For instance, if it crosses with 'Dragon Ball', how would Mori Jin's power compare to Goku's ki.
The theme of friendship is quite common. For example, in a crossover with 'My Hero Academia', the characters from both series form new friendships and alliances. They learn from each other's strengths and weaknesses. Also, the theme of adaptation is present. Characters from Highschool DxD have to adapt to the new rules and environments of the crossover world. Say, if they cross over with a post - apocalyptic world, they need to figure out how to survive and use their powers in that new context.

There's also a bit of a cultural clash theme sometimes, as the two series have different settings and norms.
Power - up themes are common. When characters from different animes cross over, they often gain new powers or find ways to enhance their existing ones. For instance, if a character from a magic - based anime crosses with Highschool DxD, they might learn about the Sacred Gears and incorporate that into their own power set.
Power. Since it involves dragon gods, a common theme is the acquisition and control of great power. Characters often struggle with newfound dragon god - like abilities.
One common theme is the clash of different worlds. Since it's a crossover, there's always the idea of how the rules and cultures of one world interact with another. For example, in a God Eater and Final Fantasy crossover, the high - tech weaponry of God Eater might seem strange in the more magic - based Final Fantasy world.
Power - up is a common theme. Since Issei becomes a Dragon God, the fanfictions often explore his new powers and how he uses them to overcome challenges. Another theme is relationships. His relationships with other characters, like Rias and his friends, might change due to his new status.

One great 'god of highschool crossover fanfiction' is 'The God of High School Meets Naruto'. It combines the action - packed world of 'The God of High School' with the ninja universe of 'Naruto'. The characters from both worlds interact in really interesting ways, like Mori Jin using his power against Naruto's shadow clones.
Survival is a very common theme. Given the zombie apocalypse setting, characters are constantly fighting for their lives, looking for food, shelter, and ways to avoid being bitten. Another theme is friendship. In these fanfictions, friends stick together through thick and thin. They support each other and often have to make sacrifices for one another.
Romance is a huge theme as well. It could be between a Shinto - inspired character and one of the main characters from Highschool DxD. For example, a love story between a kitsune (a common Shinto - related creature in fanfictions) and Issei. The cultural differences between Shinto and the other elements in the story can add an interesting dynamic to the romantic relationships.
