Maybe they are completely misinformed. They might have heard some wrong rumors or got confused with some other works that might have some loose connection to Bermuda but are not related to 'Harry Potter' at all.
Perhaps they have a very muddled understanding of the concepts of original works and fanfiction. They might be under the impression that any fictional work that has elements of mystery or magic can be related to other such works in a fanfiction - like way. But 'Harry Potter' is an independent creation with no relation to Bermuda in the context of being fanfiction. It's also possible that they are just trying to create a strange and untrue statement for the sake of getting attention.
Some people might be misinformed. They could be confusing the popularity and the large amount of fan - created content around 'Harry Potter' with it being fanfiction itself. Just because there are a lot of fans making their own stories in the 'Harry Potter' universe doesn't mean the original work is fanfiction. The original is a creative masterpiece by J.K. Rowling.
The misunderstanding could be that they don't understand the origin of the 'Harry Potter' series. It was created by an author as an original work, not something based on other fan - created ideas.
The main misunderstanding could be a lack of understanding of what each entity is. Harry Potter is a complex and well - established fictional world, while Oryx is something else entirely. Maybe the person making the claim has misinterpreted some crossover concept in a very wrong way or has a fundamental confusion about the nature of fanfiction.
It could be that they've seen some really out - there fan theories or crossovers that made them misinterpret things. Some people like to create wild combinations of different fictional elements, and this might have led them to this strange idea. However, in reality, the two are completely separate entities with their own identities and storylines.
Well, maybe someone who doesn't really understand the essence of either could make such a strange claim. They might be confusing the elements of magic in both concepts. But really, it's a very far - fetched idea.
Maybe it's just a really out - there and misinformed idea. Some people might be so used to mashing up different concepts in their minds that they make this odd connection, but it has no basis in fact.
Well, it might be a very strange and misinformed idea. Maybe someone who doesn't really understand either franchise very well just made a wild connection in their head. But as we know, Harry Potter is about magic and wizards, and Sonic is about a speedy hedgehog. There's no logical basis for such a claim.
They might be very confused. Maybe they haven't actually read either the Harry Potter books or Greek goddess fanfiction properly.
It could be due to a misinterpretation of some common elements that they think are shared but are actually not. For example, both series have characters with special powers. But the nature of those powers is completely different. In Harry Potter, magic is more about spells and potions, while in Naruto, the Uchiha's power like the Sharingan is a ninja - related ability. People who don't fully understand these differences might wrongly think Harry Potter is an Uchiha fanfiction.
Maybe someone who is very creative and looks at the broad concept of magic in both. They could see the heroic aspects of Harry Potter and compare them to Arthur Pendragon's heroism. But really, it's a stretch. Harry Potter has a very different set of rules for magic and a different kind of society compared to the Arthurian world.
