Well, in a 'Harry Potter raised DC crossover fanfiction', perhaps Harry is raised by Wonder Woman. He could grow up learning about Amazonian values along with his own magical heritage. His magic might be seen as a new form of power in the DC world. For example, he could use magic to create protective shields during battles against the forces of Ares. Or he could be raised by the Flash, and use his magic to help the Flash with time - related problems, like creating a time - freezing spell to stop a time - traveling villain.
I think Darkseid would be the most unexpected. Imagine Harry Potter being raised in Apokolips. He would have to adapt his magic to survive in such a harsh and evil - dominated place. His magic could potentially be a threat to Darkseid's rule, or he could learn some dark magic - like powers from Darkseid's regime, which would completely change his character and the way he uses magic.
A very common one is Sherlock Holmes. Imagine Harry being raised by the brilliant detective. He would grow up with a sharp mind for deduction, which could be very useful in solving the mysteries within the wizarding world. Another is Gandalf from 'The Lord of the Rings'. Gandalf could teach Harry a different kind of magic and wisdom, which would shape Harry into a very different kind of wizard.
It would be a wild and chaotic story. Harry would grow up in a very different moral environment. He might learn some devious tactics from the DC villains. His magic could be used in ways that are more self - serving rather than for the greater good like in the original Potter stories.
One common theme is the clash of different power systems. In Harry Potter, there's magic, and in DC, there are super - powers. Fanfictions often explore how these two types of powers interact, whether they complement each other or cause conflict.
In this fanfiction, Harry's powers would likely be shaped by the cutthroat nature of the DC villains. He might learn to use magic more aggressively, perhaps even using it to intimidate or control others. For instance, instead of using a simple stunning spell in self - defense, he could use it to subdue someone for his own purposes. His magical development would be less about following the rules of the wizarding world and more about achieving his own, possibly villainous, goals.
One possible plotline could be Harry being raised by characters from a different magical universe, like the Narnia characters. This might lead to him having a very different understanding of magic and his role in the wizarding world. Another could be if he was raised by characters from a superhero universe, which would likely result in him having some unique combat skills in addition to his wizardry.
It could be really exciting. Maybe Harry Potter characters could visit Gotham City. Harry could use his magic to help Batman fight crime in a way that normal gadgets can't. For example, he could use spells to disarm villains from a distance or create magical barriers to protect civilians.
One idea could be that Harry Potter and his friends are transported to the DC Comics universe. They could team up with the Justice League to fight a common enemy like Voldemort who has somehow gained powers from a DC Comics villain. For example, Voldemort could have made a deal with Darkseid to gain more power in exchange for helping him conquer the wizarding world first. Then, Harry and the likes of Superman, Batman, and Wonder Woman would have to combine their magical and super powers to stop them.
There's 'Magic and Metahumans'. This fanfiction has a great plot where the Death Eaters from Harry Potter somehow end up in Metropolis. Superman has to deal with their dark magic while Harry and his friends try to find a way back to their world. It's full of action and interesting character dynamics.
