Well, in such a fanfiction, Harry Potter being raised as a Winchester would likely mean a whole new set of adventures. The Winchesters are used to dealing with demons and monsters. Harry could bring his magical knowledge to that world. For example, he could use spells to track down creatures that the Winchesters usually hunt with their research and weapons. His upbringing in the Winchester way would make him more of a fighter, perhaps less reliant on the wizarding world's institutions.
Definitely Sam and Dean Winchester. They would be like his surrogate brothers or mentors. Then there's Castiel, the angel. He could have some interesting interactions with Harry, perhaps being intrigued by his magic. Bobby Singer could also be there, guiding Harry in the ways of hunting.
One possibility is that Harry would grow up with a very different set of skills. Jason Winchester is often associated with hunting and survival skills. So Harry might be trained in those areas instead of magic at first. He could be more physically adept and have a more hands - on approach to dealing with threats. For example, instead of using a wand to fight off dark wizards, he might use a weapon like a knife or a gun as Jason Winchester would. Also, his view of the world could be shaped by Jason's more gritty and down - to - earth perspective, rather than the magical world view he has in the original Harry Potter series.
Well, it might be hidden at first. Since the Winchester world is more about physical combat and hunting non - magical threats, Harry might have to keep his magic a secret. He could use it in a very discreet way when it's absolutely necessary, like when facing a magical creature that normal Winchester methods can't handle.
There could be. Fanfiction writers often come up with unique and creative crossovers. However, it also depends on how popular the concept of combining 'Harry Potter' with 'Winchester' is among the fanfiction writing community. It might take some digging through different fanfiction platforms to find it.
I'm not entirely sure specifically as I haven't read that exact fanfiction. But generally, it might be about a female version of Harry Potter being a fan of the Winchesters. It could involve her getting into the world of the Winchesters, maybe having adventures inspired by them or trying to meet them.
I'm not entirely sure specifically as there could be many different interpretations in fanfiction. It might involve a scenario where a character from the Winchester universe saves Harry Potter in some way, perhaps from a dark wizard or a dangerous situation within the magical world of Harry Potter.
A common theme is the clash and combination of different worlds. Harry's magical world with spells and potions meets the Winchester's world full of demons and angels. Another theme could be the idea of family. Both Harry, who has his own complex family history in the Potter series, and the Winchesters, with their strong brotherly bond, might explore family relationships in new ways in these fanfics.
One great fanfiction could be 'The Unlikely Alliance'. It's a story where female Harry Potter, who has her own set of magical skills, teams up with Dean Winchester in a world where the supernatural and magic collide. The author does a great job of developing their relationship and the plot is full of action and mystery.
