The possible misunderstanding could stem from a very loose understanding of both 'Harry Potter' and 'One Piece'. If someone only has a superficial knowledge of the two, they might think that since both have elements of adventure and a central character with special abilities (Harry's magic and Shanks' strength), they can be related in the form of fanfiction. Also, in the era of the internet where a lot of mash - ups and fan - made crossovers exist, they might have misconstrued the difference between a legitimate fan - created work within a single universe and this completely inappropriate connection between two separate universes.
One possible misunderstanding could be a lack of knowledge about the two different fictional worlds. Someone who is not well - versed in either 'Harry Potter' or 'One Piece' might randomly combine elements from both. Another reason could be a misinterpretation of the concept of fanfiction. They might think that just because they can imagine some crossover in their head, it means one can be considered fanfiction of the other, without understanding the proper boundaries of different fictional IPs.
Maybe some people who are not familiar with the real 'Harry Potter' story misinterpret it. They might have heard some false rumors or misread some fan - made parodies and thought it was related to archdemons.
Perhaps it's a very strange and misinformed idea. It could be someone's warped view of trying to connect two completely different things. Maybe they think there are some hidden or symbolic similarities, but it's really hard to fathom any real connection.
This statement is not valid in the traditional sense. 'Harry Potter' is a well - established and original fictional universe created by J.K. Rowling. It has its own unique storylines, characters, magic system, etc. Shanks is from 'One Piece', an entirely different fictional work. Fanfiction usually involves using the existing elements of a particular work to create new stories, but these two come from completely different IPs and there's no real connection to say that 'Harry Potter' is Shanks fanfiction.
This statement is completely untrue. 'Harry Potter' is a unique and original fantasy series created by J.K. Rowling. It has its own independent world - building, including Hogwarts School of Witchcraft and Wizardry, the Ministry of Magic, and a host of unique characters like Harry, Hermione, and Ron. There is no relation to 'Lucifer' fanfiction at all.
It could be a really out - there attempt at finding a dark and historical parallel. Maybe someone thought about the dark aspects of both characters, like the idea of Harry facing Voldemort being compared to Vlad the Impaler's battles. But really, it's a very far - fetched connection.
Maybe the author just wants to add some humorous or unexpected elements to the story. In fanfiction, authors often take creative liberties and might portray Harry in this way to show his inexperience or awkwardness in romantic situations.
The origin might be from extreme religious groups. They may see the magic elements in Harry Potter as going against their religious dogma and thus label it as devil - related. They might not understand that it's just a fictional story.
One possible plotline could be that as a female Harry Potter, she discovers the world of One Piece and becomes a huge fan of Shanks. Maybe she tries to incorporate some of the values she admires in Shanks, like his loyalty and courage, into her fight against Voldemort. For example, she might be inspired by Shanks' selfless act of sacrificing his arm to save Luffy and be more willing to put herself in danger to protect her friends at Hogwarts.
Maybe it's just pure creativity gone wild. Some fans might want to see how the two different mythologies interact.
It could be that the author was trying to break the boundaries of traditional fanfiction. They wanted to create something completely different by merging two very popular and distinct fictional worlds. They might have been inspired by the idea of exploring new narrative possibilities that come from combining such different concepts as the wizarding world of Harry Potter and the superhero world of Wonder Woman.
