Well, in certain fanfic, Harry could react with more caution. He might be constantly doubting the motives of those around him, even his closest friends. Maybe the author is exploring a 'what if' scenario where Harry has had some experiences that made him more paranoid. So instead of jumping into things like he did in the original story, he takes his time to assess every situation.
There are fanfics where Harry Potter reacts with a greater sense of world - weariness. He has been through so much in the original series, and in these fanfics, the authors might take that further. He could seem less enthusiastic about new adventures or challenges. Instead of being eager to face the next big threat, he might be more reluctant, thinking about all the sacrifices and hardships he has already endured.
In fanfic, Harry might react differently due to various reasons. For example, if the fanfic is an alternate universe story, he could be more confident or more hesitant compared to his original character. If the story focuses on a different aspect of his personality, like his sense of humor, he may react with more sarcasm or playfulness.
Well, Harry Potter is a rather humble character. He might initially feel a bit embarrassed to see himself as the center of so many fictional stories created by fans. If the fanfic portrays him as a hero in new adventures, he would probably be honored. However, if it misrepresents his friends or the values he holds dear, he could be a bit indignant. He would likely approach it with an open mind but also with a sense of protectiveness towards his own story and those he loves.
He may be confused at first. Fanfics can be very different from his real experiences. He might wonder why people write such things about him and his world.
Harry might initially be shocked and confused. He's used to Hogwarts being his safe haven, so when it turns against him, he'll be at a loss. He may try to prove his innocence by finding evidence or confronting those who are spreading lies.
Well, in some fanfics, Tom Riddle is portrayed as having a bit more humanity. Maybe he has a love interest that makes him question his dark ways. This is different from the books where he seems fully committed to the dark side from a young age.
In some Harry Potter fanfics, magical creatures like the werewolf might be portrayed more sympathetically. Instead of just being seen as dangerous during full moons, they could be shown as struggling with their condition. For example, a fanfic might focus on a werewolf trying to lead a normal life among wizards.
Heirs in Harry Potter fanfic are often shown as having a special mission or purpose. They might be the only ones who can unlock a certain mystery or power. For example, an heir to Ravenclaw could be the only one who can solve the riddle to access a hidden library. Descendants, on the other hand, are more about the family connection. They may be part of a large family and have normal lives within the wizarding world, like the numerous descendants of the Black family who have different personalities and magical abilities but not all are heirs with a specific task.
He could be initially shocked. Harry, who has trusted Ginny deeply, would find it hard to believe at first. He might go through a period of denial, trying to find excuses for Ginny's actions.
Harry might react with a sense of both curiosity and discomfort. The fanfic might have elements that are completely foreign to his understanding of his own story, yet he could also be intrigued by the creativity of it. He might start to wonder how much of his own life has been turned into something so different in the minds of others. He could also feel a bit protective of his own story and those of his friends, not wanting it to be misrepresented too much in the fanfic.
Remus might be a bit more reserved. He'd approach the fanfics with caution, but he'd also be touched by the stories that explored his struggle with being a werewolf in more detail. He might find comfort in knowing that fans understood his inner turmoil to some extent.
