Supernatural and Harry Potter Castiel Fanfiction: Who could be Castiel's best friend in the Harry Potter universe?

Yes, there are quite a few. You can start by looking on fanfiction websites like Archive of Our Own. Just search for 'Harry Potter Castiel' and you'll find various stories that blend the magical world of Harry Potter with the character of Castiel. Some might be about Castiel somehow ending up in the Harry Potter universe, or vice versa.

Well, one possibility could be that Harry has some sort of angelic powers inherited from Castiel. He might use these powers to fight Voldemort in ways that are different from the original story. For example, he could heal the injured more effectively during the battles.

Well, a frequent theme is the exploration of different power structures. In Harry Potter, there's the hierarchy in the wizarding world, and in Castiel's world, there are hierarchies among angels. Fanfiction might look at how these different power systems compare and contrast. Also, friendship across different universes is a common theme. Characters from Harry Potter and Castiel's world forming bonds despite their differences.

One idea could be Castiel getting transported to the Harry Potter world. Maybe he tries to understand the magic there using his angelic knowledge. Another plot could involve Castiel teaming up with Harry Potter to fight a common dark force that is threatening both the wizarding world and the Supernatural world.

Some might focus on Castiel being a new kind of wizard in the Harry Potter universe, or Harry Potter characters interacting with Castiel in a unique way.

The uniqueness lies in the combination of two distinct fictional universes. Harry Potter has its own magic system, characters, and storylines set in a wizarding world. Castiel comes from the Supernatural universe with angels, demons, and a different kind of supernatural lore. When combined in slash fanfiction, it creates a whole new set of relationships and scenarios that you wouldn't find in the original works.

One common trope is the 'fish out of water' situation where Castiel is suddenly in the Harry Potter world and has to figure out how things work. Another is the 'powerful ally' trope where he becomes a crucial help to Harry and his friends.

Definitely. There are fanfictions that blend the two universes in unique ways. For example, some might have Castiel interacting with the Hogwarts professors, sharing his otherworldly knowledge. It's a great way to see two beloved fictional worlds collide.

The presence of Castiel makes it unique. Castiel is from a completely different fictional universe with his own set of powers and characteristics. When combined with Harry Potter's world, it creates a whole new set of story possibilities. For example, his angelic powers can interact with magic in unexpected ways.

He would probably be more otherworldly. Harry might have an air of mystery around him that the original Harry didn't have. His actions could be more guided by a sense of divine purpose.
