If Harry Potter is the wife in the story, his relationship with Ginny would be very different. Ginny could be the main breadwinner or the one more involved in the outside world of magic, like fighting dark wizards. Harry would be at home, taking care of their family. His relationship with Dumbledore might also change. Dumbledore could see Harry in a more nurturing role, and perhaps rely on Harry to bring a sense of family and stability to the wizarding community. And his relationship with the other Hogwarts students would be different too. They might view him as a more domestic figure, someone who is there to support them in a different way than in the original story.
Well, with Harry being the son of Set, his connection to Hagrid could be an interesting one. Hagrid might see him as even more special and perhaps be a bit more protective. As for Snape, Snape would likely be very suspicious of Harry's new origin. His relationships with his classmates would be altered too. Some might idolize him for his link to a powerful god, while others might be jealous. And when it comes to Voldemort, Voldemort might see Harry as an even greater threat and try to find ways to use or destroy his connection to Set.
There could be a relationship with the Devil's Snare. Usually a dangerous plant, but if Harry can talk to it, he might be able to negotiate with it. He could ask it not to attack his friends or himself. And the Devil's Snare could provide him with information about other dangerous areas in Hogwarts where similar dark plants or creatures lurk.
Perhaps he'd have a tattoo of a phoenix, symbolizing his connection to Dumbledore and the idea of rebirth. Or a tattoo of a stag, which was his father's animagus form. This could be a way to carry a part of his family heritage with him at all times. In some darker fanfictions, he might have a tattoo that is a mark of the dark forces he has fought against, like a Death Eater symbol that he has defaced or modified to show his victory over them.
Hermione would probably be devastated. She was Harry's closest friend and ally. She might be filled with rage towards Vernon and vow to seek justice. Ron would also be heartbroken and might want to take matters into his own hands against Vernon.
It could be a character from a different wizarding school that we haven't heard of before. Maybe a student from a school in a far - off land like the Americas or Asia. They would bring in different magical traditions and skills.
Another aspect could be the never - ending battle against Voldemort. The fear, the stress, and the constant danger might have taken a toll on his mental health. He might think that dying would end this cycle of fear and uncertainty.
A Thestral could also be a familiar for Harry. Since he can see Thestrals, it makes sense in the context of fanfiction. Thestrals could provide a unique form of transportation for Harry and also have some special abilities related to the afterlife or death magic that could be explored in the story.
He could meet the Dalton students. They might be very different from his Hogwarts friends, maybe more focused on academic magic in a different way.
Well, in fanfiction, anything can happen. Maybe in this particular fic, there's some sort of magical cross - over event. Perhaps the author has created a new world where the rules of the Potterverse and the world Clint is from (like the Marvel universe) collide. It could be that some powerful magic or a strange experiment made it so that Fem Harry Potter and Clint end up together and get married.
In fanfiction, anything can be possible. Magic could be used in a way that alters time or memories. Maybe a spell gone wrong made Harry Potter Draco's father. It could also be a result of some dark magic or a powerful charm that changed the family ties in a very unexpected way.
