Fanfiction ideas combining Harry Potter and Gabriel from Supernatural

One idea could be that Loki, being the mischievous character he is, finds his way into the world of Harry Potter and Supernatural. He could start causing chaos in Hogwarts by disguising himself as various characters. In the Supernatural world, he might team up with the Winchester brothers for a short time, but then double - cross them for his own amusement.

One idea could be that Harry Potter, as an Animagus, somehow gets transported to the Marvel universe. He could team up with the Avengers in his animal form, perhaps using his unique abilities to gather intelligence. For example, as a stag, he could move quickly and unnoticed in certain terrains, providing valuable information to the Avengers before a battle.

Well, Gabriel could be a key figure in helping Harry Potter understand some of the deeper mysteries of magic. Since Gabriel has a different kind of power in the Supernatural world, he could show Harry that there are other ways to use magic that are not taught at Hogwarts. For instance, he could teach Harry how to use magic to manipulate time on a small scale, which could be useful in Harry's fight against the Dark Arts. And Harry, in turn, could introduce Gabriel to the rich magical culture and history of the wizarding world, like the story of the four founders of Hogwarts or the origin of the Hallows.

Maybe in a fanfiction, Harry Potter and his friends accidentally stumble upon a hidden Cybertronian relic. This relic has some sort of power that attracts Megatron. Harry and his friends then have to defend the relic from Megatron while also trying to figure out what it does and how to use it to their advantage in the fight against Voldemort.

One idea could be a crossover where Harry Potter accidentally travels to the One Piece world and meets Whitebeard. He could learn about their different forms of magic and power, and together they face a new threat that combines the dark magic from his world and the powerful pirates in the One Piece world.

One idea could be a crossover where Harry Potter accidentally ends up in the world of Ranma 1/2. Maybe he's on a magical experiment gone wrong and lands in Nerima. He could use his magic to help Ranma deal with his curse, like creating a spell to keep him from changing into a girl when splashed with cold water.

Another concept could be a crossover where the magic in the Harry Potter universe has an unexpected effect on Android 18. For example, it could start to interact with her android systems in strange ways, giving her new powers or abilities that are a combination of magic and her android technology. This would lead to a whole new set of adventures as she tries to figure out what's happening to her.

One idea could be that Gandalf somehow gets transported to the Harry Potter universe. He could become a mentor to Harry, using his vast magical knowledge and wisdom from Middle - earth. Maybe he helps Harry understand some ancient magic that even Dumbledore wasn't fully aware of.

One idea could be that Hawkgirl somehow gets transported to the Harry Potter universe. Maybe she arrives during a Quidditch match and her flying skills astound everyone. She could then join forces with Harry and his friends to fight against the dark forces in Hogwarts, using her Nth metal mace and flight abilities in unique ways.

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.
