Well, it could be that Sparda takes Harry under his wing after seeing the boy's potential and the difficult situation he's in at the Dursleys. Sparda might train Harry in some unique ways, combining magic with his own demon - slaying skills. Harry could learn to be more self - reliant and gain a new perspective on his power.
In a 'Harry Potter adopted by Sparda' fanfiction, the plot could involve Sparda sensing the great power within Harry that is being misused or at risk in the wizarding world. He adopts Harry and takes him to a place where he can grow and learn without the interference of Voldemort or the corrupt elements of the wizarding society. Harry would then start to learn about Sparda's family, their history, and how to use his magic in a more efficient and different way. He might also get some sort of weapon or tool from Sparda's world that aids him in his battles against the dark forces in both worlds.
One possible main antagonist could be Voldemort still. Even though Harry is now under Sparda's protection, Voldemort would see Harry as a threat and would try to get rid of him. Another could be some of the demons from Sparda's world who see Harry as an intruder or a threat to their plans in the new world order that Sparda is trying to create with Harry by his side.
In a 'Harry Potter Heir of Sparda' fanfiction, the plot might involve a mysterious connection between the wizarding world and the world of Sparda. Harry could be led to an ancient prophecy that links him to the Heir of Sparda. As he delves deeper, he meets characters from the Sparda universe who teach him how to harness his new powers. He then uses these powers not only to defeat Voldemort but also to protect the entire magical world from threats that were previously unknown.
Well, it could involve Harry having some of Dante's devil - slaying abilities. Maybe he uses them to fight the dark forces in the wizarding world that Voldemort represents in a more unique way than just magic. For example, he could have enhanced speed and strength like Dante to take on Death Eaters.
One possibility is that Harry Potter, in this fanfiction, might be exposed to a whole new set of dark magic and powers that demons possess. The demons could see his potential and decide to raise him in a way that is completely different from the wizarding world he knew. Maybe they would teach him to use his magic more aggressively or in ways that are considered unethical in the normal wizarding community.
Well, perhaps Crowley would use his dark powers to protect Harry in a rather unorthodox way. He might introduce Harry to a world of magic that has a more demonic or morally grey tint compared to the traditional Hogwarts magic. Maybe he'd train Harry to be more self - reliant and less bound by the rules of the wizarding world.
In this fanfiction, it could start with Ahsoka sensing a great power within the wizarding world. She investigates and finds Harry Potter, a young boy with a tragic past. Ahsoka, being a protector, adopts him. As Harry grows, Ahsoka trains him not only in magic but also in the ways of the Jedi. He might learn to use a lightsaber along with his wand, and they could face threats from both the Star Wars and Harry Potter universes together, like the Sith and Voldemort's followers.
Well, one possible plot could be that after Harry's difficult life at the Dursleys, Fleur Delacour discovers his situation. She decides to adopt him out of pity and a sense of justice. Harry then gets to experience the wizarding world from the perspective of the Delacour family. He might learn different magic techniques that are more common in the French wizarding community. He could also form new friendships with Fleur's younger sister or other relatives. And perhaps he'll have a different role in the fight against Voldemort, with the support and resources of the Delacour family.
Well, one possibility is that Harry grows up with the Inuzuka clan's values of loyalty and a strong bond with their ninken. He might learn their unique fighting styles and become a very different kind of wizard. For example, he could incorporate the Inuzuka's agility and teamwork into his dueling skills.
Well, perhaps Harry Potter, instead of growing up with the Dursleys, is adopted by Saitama. Saitama might teach Harry some of his simple yet effective fighting techniques. Harry could then use these in the wizarding world, adding a whole new dimension to his battles against dark wizards. Maybe he'd also introduce Saitama to the magical world, and Saitama would be super nonchalant about all the magic around him.
The plot could involve the occultist using his adoption of Harry as a way to gain power within the wizarding world. He might use Harry as a symbol or a tool. Harry, on the other hand, could start to learn about different forms of magic from the occultist that make him question the traditional magic he has known. He could face challenges from the Ministry of Magic who might be suspicious of the occultist's motives. Harry would then be in a difficult position, having to choose between his loyalty to the occultist who has taken him in and his loyalty to the wizarding world that has been his home in a sense.
