Fanfiction ideas involving Harry Potter, Fenrir, and Loki

In the fanfiction, Fenrir could be a part of an ancient prophecy that involves both the Harry Potter world and Loki's domain. Harry Potter, as the chosen one in his world, is destined to face Fenrir. But Loki has his own plans regarding the prophecy. He tries to manipulate the situation so that he can control the outcome. This would create a complex web of power struggles and alliances.

One idea could be that Loki, being the mischievous character he is, finds his way into the wizarding world of Harry Potter. He could start causing chaos in Hogwarts, perhaps by disguising himself as a student or a professor and playing pranks that are far more elaborate than those of the Weasley twins. For example, he might turn the entire Great Hall into an ice rink during breakfast time.

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.

Maybe in a fanfiction, Medusa is a distant relative of one of the magical creatures in the Harry Potter universe. Harry, Ron and Hermione discover this connection during their research for a class project. They then go on an adventure to find out more about Medusa and how her powers could be related to some of the dark magic they've encountered.

One idea could be a story where Rose, who might be a new student at Hogwarts, befriends Dobby. Harry Potter could then play a role as a mentor to Rose, guiding her through the magical world. Dobby could use his unique magic skills to help Rose in various tasks around the school, like finding hidden passages.

Perhaps a fanfiction where the Basilisk is not a solitary monster but part of a larger, more complex ecosystem in the Chamber of Secrets. There could be other magical creatures that depend on the Basilisk in some way, and when the Basilisk is in danger, these other creatures come to its aid. This would change the whole dynamic of how the characters interact with the Basilisk and the Chamber of Secrets.

One idea could be a story where Hermione and Draco are paired up for a special project at Hogwarts. They start off hating each other as usual, but as they work together, they begin to understand each other better. Harry could be suspicious at first, but then realizes that their newfound friendship could be beneficial for the wizarding world. For example, Draco might share some Slytherin secrets that help in a battle against the dark forces.

One idea could be that Lilith Lemon is a new student at Hogwarts who has a mysterious past. She meets Harry Potter and they end up on an adventure together to uncover a hidden magic within the school. Maybe she has a special ability related to divination and helps Harry foresee some upcoming danger.

One idea could be a story where Dudley and Piers start to see Harry in a new light after he saves them from a magical threat in the Muggle world. They then become sort of secret allies to Harry, helping him out when he's in the Muggle neighborhood.

One idea could be a time - travel fanfiction where Hermione goes back in time and has to face Bellatrix in a magical duel. Harry could be caught in the middle, trying to protect Hermione. Maybe Bellatrix has a secret that could change the course of the wizarding war, and Hermione discovers it.
