Well, it could be a story full of cultural clashes. Harry, coming from the wizarding world in the 'Harry Potter' universe, being adopted by Shikaku from the 'Naruto' world. Shikaku might be really strict about ninja training and values, while Harry has his own set of magical skills and ethics. Maybe Harry would struggle to adapt to the physical and combat - oriented ninja training at first, but then use his magic in unique ways during their missions.
A plot twist might be that Harry's past enemies from the wizarding world somehow find a way to cross over into the Naruto world. This would force Shikaku and Harry to team up not only with the ninjas but also with some of Harry's old friends from Hogwarts. It would create a really chaotic and interesting situation where two different worlds' powers and skills collide.
In this fanfiction, Naruto might grow up with a different set of values and skills. Shikaku is a strategic thinker, so Naruto could become more tactically minded. He may also form closer bonds with the Nara clan.
In a 'harry adopted by euryale fanfiction', it could start with Harry being lost or on the run. Euryale, seeing his potential or feeling a connection, decides to adopt him. She could introduce him to a whole new world of magic that is different from what he has known in Hogwarts. For example, a magic more related to the ancient Greek mythology which she is a part of. And Harry would have to adapt to this new life and learn from Euryale while also dealing with any threats that might come from his past in the wizarding world.
Well, perhaps in this fanfiction, Zeltech could be a powerful wizarding family or organization. The plot might involve Harry being adopted by them due to some special circumstances, like they saw his great potential and wanted to protect him from the Dursleys. They could then train him in unique forms of magic that are different from what he would learn at Hogwarts.
Well, in such a fanfiction, Harry might be given a very different education. The Malfoys could try to indoctrinate him with pure - blood supremacist ideas at first. But as he grows, he might rebel against it. He could also be exposed to a different social circle within the wizarding world. Maybe he would have more interactions with other Slytherin families and this would change how he views things like House rivalries. And his relationship with Dumbledore would be very strained as the Malfoys are not on good terms with Dumbledore.
One possible plot could be that Harry, who might be from the Harry Potter universe, is suddenly adopted by Batman in a crossover world. Batman could see Harry's potential and take him under his wing. Harry would then be trained in Batman's ways, learning combat and detective skills. He might also use his own magic in a new way to help Batman fight crime in Gotham, like using magic to disarm villains or solve mysteries that normal means can't.
In such a fanfiction, Harry might gain access to Flamel's vast knowledge of alchemy. Maybe he would learn how to create powerful potions and magical items much earlier. Flamel could also protect Harry from Voldemort more effectively with his ancient magic and connections.
In this fanfiction scenario, since Zelretch is a very powerful and mysterious figure, Harry's life would likely take a very different turn. He could be exposed to time - traveling or multi - dimensional magic. Zelretch might also protect Harry from Voldemort in a way that no one else could, using his extraordinary powers. Harry would grow up in an environment full of ancient and arcane knowledge, which would shape him into a very different wizard compared to the original series.
If Harry Potter was adopted by Batman in fanfiction, it would be a wild blend of two very different universes. Batman's Gotham City is a dark and gritty place, full of crime and corruption. Harry, coming from the magical world of Hogwarts, would be in for a shock. However, Batman would likely see the potential in Harry's magic and use it to his advantage. For example, Harry could use magic to help Batman solve cases more quickly or to protect Gotham in ways that normal technology couldn't. At the same time, Harry would be exposed to Batman's no - nonsense approach to fighting evil, which could make him a more formidable wizard in the long run.
Well, it could be a really wild story. Constantine is a very different character from the Potterverse. Maybe he'd teach Harry some dark magic defense skills that are way more unorthodox than Hogwarts teachings. Harry might also get involved in Constantine's battles against demons and other supernatural threats, which would be a huge change from his normal Hogwarts life of dealing with Voldemort and Death Eaters.
