It could be an older wizard who has turned his back on the traditional ways that the group in the fanfic adheres to. Maybe he has discovered a new form of magic that is considered taboo by the others, and so they see him as an outsider, not one of them. He might also be trying to bring about changes in the wizarding world that the group is not ready to accept, such as more integration with non - magical people in the fanfic's story.
It could mean that in a Harry Potter fanfic, there's a character who is not considered part of a particular group within the fanfic's story. Maybe he has different values or goals compared to the rest of the characters who are united by something specific in the fan - created story.
It could be Harry Potter himself. He's always been one to help others, especially those in need. He might see a new student being harassed by Slytherins and step in, saying 'one of us will help you'.
Hermione would be a great candidate. She's smart and could research all about space magic before they go.
Yes, in some fanfictions, Harry Potter discovers that his identity is more complex than he originally thought.
Well, without reading it, it's hard to say exactly. But generally, in a Harry Potter fanfic, it might be about a situation where one of the characters from the wizarding world offers to help someone. It could be a Hogwarts student, a teacher, or even a magical creature. Maybe it's related to a dangerous quest, like facing Voldemort or his Death Eaters, or perhaps it's about something more mundane in the wizarding world, like passing an exam at Hogwarts.
Harry Potter could survive in the Forbidden Forest by making allies. He could befriend the centaurs or the friendly spirits in the forest. They could help him find food, water, and warn him of any approaching danger.
In this fanfic, Harry as a Cocker Spaniel could have a different kind of Patronus. Instead of a stag, it could be something related to his dog nature, like a really powerful dog breed from the wizarding world. His adventures could include getting into all sorts of trouble in the Forbidden Forest because he's more likely to run off and explore. And he might befriend some of the forest creatures in a different way than he would as a human. For instance, he could play with the centaurs' foals in a friendly dog - like way.
He could meet new professors. These professors would have their own teaching styles and areas of expertise. They might introduce Harry to different aspects of American magic that he has never encountered before.
It could refer to Sirius Black. In some fanfictions, he might not have actually died during his encounter with Bellatrix. Maybe there was some sort of magic that protected him at the last moment and he's been in hiding ever since, waiting for the right time to come back to Harry and help him in his fight against the remaining dark forces.
He might hide it because he doesn't fully understand his own fascination. Harry has always been on the side of good, but perhaps there are elements of the dark side that seem alluring in a strange way. He could be afraid that exploring these feelings would lead him down a dangerous path, so he keeps it a secret.
