A great fanfiction might involve a crossover where some of the Cthulhu Mythos creatures are brought into the wizarding world by accident. Say, a wizard experimenting with time - turners and dark magic accidentally opens a portal to a dimension full of these Lovecraftian horrors. Harry and his friends then have to quickly learn about these new threats, which are not like the normal dark wizards or magical beasts they're used to. They might need to seek help from some of the more reclusive and knowledgeable wizards, like Dumbledore, who might have some inkling about these otherworldly entities.
One interesting story could be about how the magic in the Harry Potter world intersects with the dark and eldritch horrors of Cthulhu. Maybe the wizards have to face an ancient Cthulhu - inspired threat that their normal spells can't easily handle. For example, a dark cult within the wizarding world might be trying to summon a Cthulhu - like being, and Harry and his friends have to find a way to stop it using both their magical knowledge and some new, unorthodox methods.
There could be a fanfiction where the Hogwarts castle itself becomes a battleground between the forces of magic and the creeping influence of Cthulhu. The portraits on the walls start to show signs of madness, and the secret passages lead to places filled with strange, otherworldly entities. The students might have to team up across houses to figure out what's going on and drive back the Cthulhu - related menace. It could involve a lot of exploration and discovery of forgotten magic that can counter the Cthulhu - style threats.
One interesting Cthulhu Harry Potter fanfiction could be where the dark and Lovecraftian elements of Cthulhu are introduced into the magical world of Harry Potter. For example, there might be a story where an ancient, Cthulhu - like entity is awakened beneath Hogwarts, and the students have to use both magic and their wits to deal with it. The magic in Harry Potter could be used in new and creative ways to combat the otherworldly horror of Cthulhu.
Well, one interesting aspect could be the unique crossover. Combining the dark and eldritch elements of Cthulhu with the magical world of Harry Potter can create some really strange and fascinating scenarios. For example, how would the Hogwarts students react to the presence of Cthulhu - like entities? Would the magic they know be enough to combat such otherworldly threats? It's also interesting to think about how the different mythologies and magic systems would interact.
The combination of two very different universes. Harry Potter is all about magic, friendship, and fighting against dark wizards. Cthulhu, on the other hand, is about cosmic horror and the insignificance of humanity in the face of great and ancient evils. When you put them together, it creates a whole new set of possibilities. For example, how would Harry deal with the mind - breaking horror of Cthulhu's existence? It's a clash of concepts that makes for great reading.
One interesting cthulhu mythos fanfiction could be about a modern - day detective who stumbles upon an ancient cult related to Cthulhu. He slowly uncovers the dark secrets of the cult as he delves deeper into the mystery, with each discovery leading him closer to the brink of madness.
In this kind of fanfiction, perhaps a group of young wizards are exploring the concept of Animagus transformation when they accidentally open a portal to a realm related to Cthulhu. They then have to use their Animagus forms in unexpected ways to survive and close the portal. Their Animagus forms might start to take on some Cthulhu - like features as they are exposed to the strange energy from that realm. This could lead to a lot of internal struggle as they try to keep their sanity and their wizarding identity while dealing with these new and terrifying changes.
Well, it would probably be a very strange and dark take on the Harry Potter story. Harry might grow up with a sense of the eldritch and the unknown. His magic could be influenced by Cthulhu's power, perhaps having a more chaotic and uncontrollable aspect to it. His values and view of the wizarding world would be very different from the original Harry, as he'd be raised in a cult - like environment centered around Cthulhu.
A possible plot in such a fanfiction could be that a dark wizard discovers the existence of Cthulhu through some ancient and forbidden magic. He then tries to use Animagus forms to channel Cthulhu's power. This would likely cause chaos in the wizarding world as the power of Cthulhu is not meant to be tampered with. Other characters in the story, like Harry Potter and his friends, would have to figure out how to stop this dark wizard before the world is plunged into a nightmarish state.
One interesting Harry Potter fanfiction could be about an alternate universe where Harry is sorted into Slytherin. This changes his whole dynamic as he has to navigate the house known for its cunning while still having his moral compass intact.

There are also those that explore the backstories of minor characters, like Neville's grandmother and her adventures during her time at Hogwarts.
There are many great 'Harry Potter' fanfiction stories. For example, some focus on alternative universes where the characters have different destinies. There are fanfictions that explore what would happen if Harry was sorted into Slytherin instead of Gryffindor. It could lead to a whole new set of friendships and rivalries, and a different path in his fight against Voldemort.
