Well, it could be about Harry Potter having a very different origin as the son of Crowley. Maybe he'd inherit some dark and mysterious powers from Crowley. He might struggle with the conflict between the wizarding world's values and the more unorthodox ways he was brought up with. He could also face challenges within Hogwarts as students and teachers alike might be wary of his newfound connection to a rather dark figure.
He'd probably be more morally ambiguous. Growing up as Crowley's son, he might not have the same clear - cut sense of right and wrong as the original Harry. He could be more cunning and less hesitant to use underhanded tactics if necessary.
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.
Another option is to join relevant fan communities or forums. For example, there might be specific Harry Potter - Supernatural crossover forums where fans discuss and share their fanfiction. Reddit could be a great place to look for such communities. By interacting with other fans, you can get direct recommendations for fanfics that incorporate Harry Potter and Crowley from Supernatural.
In such a fanfiction, Harry's upbringing by Crowley would likely lead to a very different Hogwarts experience. His magic might be influenced by Crowley's teachings, making it more unorthodox. He might also have a different group of friends or allies, perhaps those on the fringes of the wizarding world who are more in tune with Crowley's ways.
Fanfiction.net also has a good collection. There are many Harry Potter Crowley fanfictions there. It has been around for a long time, so there is a large archive of works. However, the interface is not as modern as AO3, but it still offers a lot of great stories if you're willing to dig a bit.
One popular trope is the 'character crossover' where characters from Harry Potter and Supernatural interact in unexpected ways. For instance, Harry might team up with Crowley to fight a common enemy. Another trope could be the 'fish - out - of - water' situation, like when a Harry Potter character is suddenly thrust into the Supernatural universe and has to adapt.
A fanfiction could also feature Crowley as a teacher at Hogwarts. He would be a very unorthodox teacher, teaching spells and magic that are on the fringes of what is considered acceptable in the wizarding world. His classes would be full of chaos and surprises, but the students would also learn a great deal about magic they never knew existed.
Yes, there are likely to be such fanfictions in the vast world of fan-created content. Fanfiction often takes well - known characters from different universes and combines them in unique ways, so it's not surprising that someone might write a story where Harry Potter is the son of Athena.
Yes, there might be such a fanfiction in the vast world of fan - created works. However, this is a very non - canonical and often extreme interpretation. The 'Harry Potter' series by J.K. Rowling has its own well - established lore and character relationships, and this fanfiction idea goes against the original spirit in a major way.
