There's also a chance that Harry is a re - imagined version of an existing character within the same universe as LexCorp. The author might have given him a new backstory and set of circumstances that led to him owning LexCorp. For instance, he could be a former employee who had a grudge and through a series of events, ended up as the owner.
It might signify that Harry is a central figure in this fan - made story who has acquired LexCorp. This could lead to all sorts of plot developments, like changing the power dynamics in the superhero - related universe of the fanfiction. He could use LexCorp's resources to fight against other villains or even heroes, depending on his motives.
I'm not sure who 'he' specifically is without more context. It could be a fan, a collector, or someone with a particular interest in the Harry Potter fandom who has managed to acquire a collection of fanfiction.
Dumbledore could be a character in the fanfiction. Maybe he knew about the island all along and left it to Harry in his will. Or he could be a guiding spirit for Harry as he figures out what to do with the island.
There could be many possibilities. It might be an original character created specifically for the fanfiction. However, it could also be a well - known house - elf from the original series, like Dobby, who in the fanfiction somehow comes to be owned by Harry Potter in a different set of circumstances. Maybe Harry saves Dobby in a more complex way in this fanfiction and as a result, Dobby becomes his house - elf.
Hermione would probably be a regular. She'd come to the cafe to study while enjoying a warm cup of Butterbeer latte. She might even bring some books from the Hogwarts library to read there.
I don't know who the author of that fanfic is. There are so many fanfic writers out there and without more information it's hard to tell.
It might imply that within the context of a fanfiction community, Harry is the one who has the rights or is seen as the originator of the Luna - related fanfiction. For example, he could have written it or commissioned it, thus 'owning' it in that sense.
Most official and well - respected fanfiction platforms would not allow such a 'Harry Potter owns Hermione' lemon fanfiction due to their content policies. Fanfiction should be about exploring the world of 'Harry Potter' in a creative yet appropriate way, like developing new magical adventures or deepening the friendships in the story.
I'm not sure specifically as there could be many different interpretations of such a fanfiction. It might be about Harry having some sort of unique relationship with Fleur in a fictional scenario created by the fanfiction writer.
It could mean that in the realm of fan - created stories, a character named Harry is in possession of fanfiction related to Nymphadora. Maybe it's part of a story where Harry has found or been given this fanfiction, perhaps for some sort of research or just out of curiosity in the fan - made narrative world.
