Yes, there might be some out there. Fanfiction often combines different fictional universes in creative ways. However, it's important to note that such fanfiction may not be officially endorsed by the creators of either Harry Potter or Highschool DxD.
Yes, there are likely many non - sexual crossovers. Fans often create crossovers to explore how the magic of Harry Potter might interact with the supernatural elements of Highschool DxD in a more family - friendly or plot - driven way. They might imagine characters from both universes teaming up to face a common enemy or sharing knowledge about their respective worlds.
Yes, there are likely some crossover fanfics out there. Writers often like to combine different popular universes to create unique stories. In such a crossover, you might see characters from Harry Potter interacting with those from High School DxD in all sorts of interesting ways, like Hogwarts students using magic in the world of High School DxD or the devils in High School DxD being introduced to the wizarding world.
It's unique because it allows for a lot of creative crossovers. For example, Harry Potter's magic system can interact with the power - based society of DxD in ways that are unexpected. The Nephilim aspect can change the power balance. It also gives an opportunity to explore different character relationships. Like, how would Harry, as a Nephilim, interact with the devils or angels in DxD? There are so many possibilities for character growth and plot development.
One possible plotline could be that a character from Harry Potter accidentally ends up in the world of High School DxD. For example, Ron could be transported there and have to figure out how to get back while dealing with the devils and angels in that world.
Well, Vampire Harry in DxD fanfiction often has a great deal of magical resistance. Since he was already a wizard, and now a vampire, his body and magic are combined in a way that makes it difficult for other magic - users to affect him with spells. His blood also has certain properties. It might be able to heal others to some extent, or it could have a corrupting influence if it gets into the wrong hands. And his vampiric powers can be enhanced over time. He can train and become stronger, faster, and more in control of his compulsion abilities. This makes him a very formidable character in the DxD fanfiction world.
In such fanfictions, Harry Potter as a vampire often has a very different character development. His experiences as a wizard in the Harry Potter world already shape him, but becoming a vampire adds new layers. For example, he may have to struggle with new instincts and powers. His moral compass might also shift as he has to deal with the vampiric nature of needing blood. He could become more solitary at first, trying to figure out his new self, and then gradually learn to use his vampire abilities in the context of the DxD world, which is full of different races and power dynamics.
One interesting 'Harry Potter Nephilim DxD Fanfiction' is 'The Nephilim Potter in DxD World'. It combines the magical elements of Harry Potter with the unique setting of DxD. The character development is quite engaging as Harry, with his Nephilim powers, navigates the complex and often dangerous world of DxD.
It's really hard to say. Harry Potter has his powerful magic from Hogwarts and his connection to Voldemort which gives him a certain power boost. But in the DxD world, characters like Great Red are extremely powerful. If Harry was able to combine his magic with the power of a Sacred Gear, he could potentially be a very strong force. However, characters like Sirzechs Lucifer also have a vast amount of power. So it could be a toss - up depending on how the crossover is written.
One idea could be that Harry Potter, while exploring some new magic, accidentally opens a portal to the DxD world. He then has to adapt to the new rules and powers there. Maybe he teams up with Issei and they use a combination of Hogwarts magic and Sacred Gears to fight off a common enemy.
