The storyline could be quite interesting. Inuyasha might introduce a whole new way of fighting dark magic with his combat skills. He could train Harry in a more physical and aggressive style compared to the normal wizard dueling. Also, the relationship between Harry and his friends might change as they try to understand his half - demon heritage.
Well, first of all, it would probably involve a lot of secrecy at the beginning. Harry might find some strange artifacts or clues that lead him to suspect that his father is not who he thought. Once he discovers the truth, Tony Stark would probably want to protect Harry in his own way, which could be very different from how the wizarding world does it. He might introduce Harry to new forms of combat using his Iron Man suits. And there would be a whole subplot about how the wizarding community reacts to having an outsider like Tony Stark be related to one of their most famous wizards. There could be jealousy, suspicion, and also a lot of excitement as they see the potential of combining magic and technology.
Well, it's a really strange crossover concept. Inuyasha is from a very different universe than Harry Potter. But if he were to be Harry's father in fanfiction, it could involve some time - travel or interdimensional magic. Maybe some dark wizard used a spell to bring Inuyasha to the wizarding world and he had a relationship with a witch. However, it would be a huge stretch of both universes' lore.
In a 'Harry Potter raised by Inuyasha' fanfiction, there are so many possibilities. Harry could be exposed to a whole new set of magical creatures that are more like the demons in Inuyasha's world. His magic might develop in a different way, perhaps being more physical and less reliant on wands. His personality would probably be a blend of Harry's original kindness and Inuyasha's brashness. He might also have a different set of friends, maybe some half - demon or spirit friends. And the story could involve him using his knowledge of both worlds to solve problems that neither world could handle alone.
Well, in this fanfiction scenario, Lily raising Harry would mean he'd be protected in a different way. Instead of the Dursleys' neglect, he'd have a nurturing environment. Lily could teach him about his father in a more personal way. Maybe he'd grow up with a stronger sense of family and heritage. Also, he might not have the same sort of scar - or it could be a mark of a different kind of magic, since the circumstances of his survival would be different.
In this fanfiction concept, the story could start with Toriel finding baby Harry on her doorstep, much like how she might take in a lost child in Undertale. She would raise him with love and care, teaching him about the world in a very different way than Hogwarts. Harry would grow up with a strong sense of right and wrong, based on Toriel's moral compass. His adventures would be different too. Instead of facing Voldemort in the traditional Hogwarts setting, he might have to deal with threats to both the wizarding world and Toriel's world. And his friends could be a mix of wizards and characters from Toriel's realm, leading to some very unique interactions and story arcs.
The storyline might involve Serena bringing a whole new set of values and skills to Harry's upbringing. Maybe she'd teach him a different kind of magic, or perhaps she'd instill in him a great sense of determination and independence from a young age. It could also be that Harry would grow up with a more athletic and competitive edge, given Serena's own nature in her original context.
One possible storyline could be that Harry discovers his true parentage. He has always felt a bit of an outcast in the wizarding world, and when he finds out he's Harley Quinn's son, he decides to explore the DC universe. There, he has to deal with all the chaos and villains while also trying to figure out his place. Maybe he teams up with Harley to take on the Joker or other threats, using his magic in ways no one in the DC world has ever seen.
A possible storyline could be that the wizarding world is in danger not just from Voldemort but from some sort of threat from the Marvel universe as well. As the son of Bucky Barnes, Harry is seen as a link between the two worlds. He has to bring together the magic of Hogwarts and the skills he has from his father to save both worlds. He might form an alliance with some Marvel characters who find their way into the wizarding world. This would create a really unique and exciting adventure, full of magic, action, and unexpected twists.
Well, in this fanfiction scenario, Harry would be raised in a different family environment. The Longbottoms, having their own history of struggle against the Dark Arts, would instill in Harry a sense of determination and a different perspective on the fight against Voldemort. His relationship with Neville would be complex yet interesting, as they would share a family bond. And perhaps, his magical education would have a different slant, influenced by the Longbottoms' way of doing things.
The storyline could start with a strange magical accident that creates a portal between the Harry Potter universe and the Marvel universe where Black Widow exists. Harry stumbles through this portal and meets Natasha. At first, they are suspicious of each other but soon realize they have a common goal of fighting evil. As they work together, they develop feelings for each other and eventually decide to get married.
