There are definitely some out there. I've come across a few where Harry has some sort of connection to Cthulhu, like he discovers Cthulhu's power in the wizarding world or is somehow related to the ancient being. It's a really cool and different take on the Harry Potter universe.
Yes, there are some interesting 'Harry is Cthulhu' fanfictions. You can try searching on fanfiction - specific websites like Archive of Our Own. Some writers explore really unique concepts in these stories, combining the magical world of Harry Potter with the Lovecraftian horror of Cthulhu.
Well, it depends on your taste. There are 'Harry is Cthulhu' fanfictions that range from light - hearted mash - ups to really dark and horror - filled ones. If you like the idea of mixing the magic and mystery of Harry Potter with the terrifying and otherworldly elements of Cthulhu, you should be able to find some good reads. Just be prepared for some really strange and mind - bending concepts.
One of the things that make it unique is the contrast in the tone. Harry Potter has a relatively positive and hopeful tone most of the time, while Cthulhu is associated with dread and the destruction of sanity. In 'Harry is Cthulhu' fanfictions, writers have to balance these two tones, which often results in a very interesting and complex story. Also, the way the magic of Harry's world might interact with the eldritch powers of Cthulhu is something that can be explored in many different and exciting ways.
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.
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.
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.
They can combine in terms of magic systems. In some fanfictions, the powerful and often incomprehensible magic in the Cthulhu universe might blend with the more structured magic of Harry Potter. For example, a spell in Harry Potter might be corrupted by Cthulhu's influence and become a more dangerous and unpredictable force.
The themes blend by pitting the light - hearted and somewhat familiar magic of Harry Potter against the mind - bending, incomprehensible horror of Cthulhu. For instance, the concept of good vs. evil in Harry Potter takes on a new dimension when faced with the amorality of Cthulhu - like beings. The wizards' sense of order and their magical laws are challenged when these chaotic and eldritch forces enter their world.
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.
Hermione would be horrified. She's always by the book, and summoning Cthulhu is the most dangerous and unthinkable thing. She'd immediately start researching ways to send it back. Ron would be scared out of his wits but also a bit in awe of the power. Harry would be conflicted, realizing he's brought something extremely dangerous into their world.
The plot might involve Harry using his magic in an unorthodox way to summon Cthulhu. Maybe he stumbles upon an ancient spell in the restricted section of the library. Once summoned, Cthulhu could bring chaos to the wizarding world. The dark and eldritch powers of Cthulhu would be in stark contrast to the more traditional magic in Harry Potter. This could lead to a struggle between the forces of Hogwarts and the indescribable horror of Cthulhu.
Well, Harry would be much more aloof and menacing. He might not interact with Hermione and Ron in a friendly way at all. Instead, he could view them as potential sacrifices or just insignificant beings. Hermione, being the intelligent one, might be terrified of Harry's newfound powers and strange upbringing. Ron would probably be outright hostile towards Harry, seeing him as a threat to the normal wizarding way of life.
