I'm not entirely sure as it could mean many things. It might be a fanfiction where Harry Potter is portrayed as an unimportant or overlooked character, perhaps in a new or alternative storyline.
The idea of focusing on a 'nobody' is interesting because it gives a fresh perspective. Instead of the usual main characters, we get to see the wizarding world through the eyes of someone who is usually in the background. It can also introduce new plotlines and relationships that we wouldn't have thought of in the original series.
You could start by looking on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just search for the title or related keywords on their search bars.
It might exist because the author was writing more for themselves than for an audience. Some people write fanfiction just to explore their own ideas and don't really focus on making it appealing to others.
It could imply that the Harry Potter fanfiction in question was not getting any attention. Maybe it was poorly written, or perhaps it was in a very niche area that few people were interested in.
Well, this title might imply a crossover where Harry Potter, who is usually a hero in his own world, is now just a 'nobody' in the Kingdom Hearts world. It could be about how he has to adapt to a new set of rules and magic systems. For example, he may have to deal with the Heartless and Nobodies in Kingdom Hearts, which are very different from the threats he faces in Hogwarts. It could also be a story about him finding his place and purpose in this new and strange world.
There are many 'a nobody harry potter fanfiction' out there. A great way to find good ones is to join Harry Potter fan groups on social media platforms like Facebook or Reddit. People in these groups often share and recommend their favorite fanfictions. They can point you to some hidden gems that deal with the concept of 'a nobody' in the magical world. These stories can add new dimensions to the already rich Harry Potter universe.
Well, it might be about Harry Potter going through his Hogwarts years but all his friends and professors are indifferent to his adventures. For example, when he faces Voldemort, no one really shows any concern or offers help. It could be a really dark and lonely take on the story.
The plot could involve Harry Potter arriving in the Kingdom Hearts world and having his magic not work as expected, making him seem like a nobody. As he explores this new world, he might encounter characters who help him understand the nature of the Heartless and Nobodies. He could then discover a connection between his own world's magic and the power of the Keyblades. There could be a struggle within him as he tries to adapt to this new world while also trying to find a way to return home, all while being seen as a nobody by most of the Kingdom Hearts inhabitants.
Maybe a new character emerges who takes advantage of the fact that nobody cares about Harry. This character could be a dark wizard who sees Harry as an easy target because no one will come to his aid. He could constantly undermine Harry's efforts and try to turn him to the dark side.
