Unfortunately, I can't name a specific 'harry potter is a cosmic entity fanfiction' right away. But it could be that in this type of fanfic, Harry is a cosmic entity who has to deal with the consequences of his newfound status. He might be hunted by other powerful entities in the cosmos or have to make difficult choices that affect the fate of all magical and non - magical beings across the universe. It could also involve a lot of world - building where the rules of the cosmos are defined and how Harry fits into this new and vast setting.
Sorry, I'm not sure of specific fanfictions with this exact title. But generally, it might have Harry Potter using his new cosmic powers to save different planets or dimensions from some sort of threat.
It could mean that the fanfiction reimagines Harry Potter as a cosmic entity. Maybe it gives him powers and a role that are related to the cosmos, like being able to control cosmic forces or having a connection to the entire universe.
One example could be a story where a group of space explorers discover a hidden civilization in a nebula in the cosmic sky. Another might be a fanfic about a star that has a consciousness and can communicate with a young astronomer on Earth. A third example could be a story of a battle between good and evil forces taking place among the constellations in the cosmic sky.
One good example could be 'The Darkness Beyond Hogwarts' in which an ancient cosmic entity begins to seep into the wizarding world, causing strange and terrifying phenomena. The characters have to deal with not only their regular magical threats but also this new, otherworldly horror.
Another example could be if the 'aunty entity' has some special powers. In the fan fiction, she could use those powers to protect a small town from an approaching storm or some other danger. Maybe she has the power to control the weather a bit, and she uses it to divert the storm away from the town, while also teaching the townspeople about the importance of being prepared for such disasters.
Some fanfictions that are overly long - winded and full of filler content can be considered the worst. They might have pages and pages of a character just thinking about nothing important or going through mundane daily activities that have no real connection to the main plot of the Harry Potter world.
One example could be a fanfic where Harry has the ability to control time without any limits, which is much more powerful than the time - turning devices in the original series. Another might be a story where Voldemort is made invincible and can defeat any opponent with a single spell, completely overpowering the other characters.
One example could be 'The Dominant Potter' where Harry discovers a new and extremely powerful form of magic early on and uses it to take charge in the fight against Voldemort. He is shown as being dominant in strategic planning and combat situations.
One example could be fanfiction that protests the lack of LGBT+ representation in the original Harry Potter series. Writers might create stories where characters are openly LGBT+, exploring their relationships and identities within the Hogwarts setting. Another could be about protesting the way house - elves were depicted. Fanfic authors may write stories where house - elves have more agency and rights, in contrast to their rather subservient portrayal in the books.
Some 'ace' Harry Potter fanfictions include time - travel scenarios. For example, a story where Harry travels back in time to meet the founders of Hogwarts. There are also fanfictions that blend the Harry Potter world with other fictional universes, like a crossover with the world of Narnia. Additionally, fanfictions that delve into the magical creatures in more depth, such as exploring the lives and cultures of the centaurs or the house - elves more thoroughly, are also great examples of the amazing and 'ace' Harry Potter fanfiction out there.
A fanfiction could have Harry Potter accidentally opening a portal to a parallel wizarding world. This regenerates the idea of the wizarding world as we know it by introducing new rules, new magical abilities, and new relationships. The author can then explore how Harry adapts to this new world and how it impacts his understanding of magic and his own identity. It's a great way for fans to expand on the original story in a creative and unexpected way.
