In the original series, Harry is an only child, so the very concept of a sister is a huge deviation. This changes the family dynamics completely. Instead of just having the Dursleys as his only family situation outside of Hogwarts, now there is this sister factor.
The character development in the original series is centered around Harry growing up without his parents and his journey in the wizarding world. In the fanfiction, the presence of a sister would likely change how he develops. For instance, he might become more bitter or more protective depending on the nature of their relationship, which is a departure from the growth we see in the original series.
In the original books, Harry is seen as a symbol of hope and acceptance. He fights against Voldemort who believes in pure - blood supremacy. But in the 'harry hates muggleborns fanfiction', Harry is on the wrong side of this equality issue. This fanfiction takes the character of Harry in a direction that is completely at odds with what we know from the original series. It also likely changes the relationships between characters. For example, his friendship with Hermione would not exist in the same way or might be completely broken in this fanfiction's universe.
Well, in the original series, the bond between Harry and the Weasleys is one of the central elements that make the story so heartwarming. They support each other through thick and thin. In the 'harry potter hates the weasleys fanfiction', this is turned on its head. The fanfiction might change the way we see Harry's character development. In the original, the Weasleys play a big role in shaping Harry into the person he becomes. But in this fanfic, with the hate relationship, it would mean a completely different path for Harry's growth and his understanding of family, friendship, and the wizarding world.
The original Harry Potter story has a strong family - love - centered theme. Harry's parents' love for him was so strong that it protected him even after their death. In the 'Harry Potter hates his parents' fanfic, this central theme is completely changed. It's a deviation that changes the whole dynamic of the relationships in the story. It's like changing the core of a flower, everything else about the story will be affected, such as Harry's relationship with his friends who also respected his parents.
In the original Harry Potter storyline, Dumbledore is seen as a wise and benevolent figure who is always looking out for Harry's best interests. However, in the 'harry hates dunbledore fanfiction', this perception is changed. It might show Dumbledore in a more negative light, perhaps making him seem more self - serving or having ulterior motives, which is a huge departure from the original where he is a symbol of good and guidance.
In the original story, Harry and Hermione are friends. But in the 'harry hates hermione fanfiction', it completely changes their relationship dynamic. It's a huge deviation as it goes against the foundation of their friendship that was built on mutual respect and support throughout the books.
The original story builds Harry as a hero who honors his parents' legacy. In the 'harry potter hates his parents fanfiction', his development takes a different path. He may not strive to be the hero that his parents would have wanted him to be. Instead, he could be on a journey to break away from their shadow, which is the opposite of the growth we see in the original story where he embraces his heritage and uses it as a strength.
In the original series, there is no indication of Harry hating Susan Bones. So this fanfiction completely changes the potential relationship dynamic. It adds a new layer of conflict that was not present in the original, which can attract readers who are interested in exploring different character interactions.
The original story builds on family love and loyalty. Lily's sacrifice is a cornerstone of the story. However, in the 'harry hates lily' fanfic, this concept is thrown out the window. It changes the way we view the Potter family relationships and the overall moral fabric of the wizarding world as presented in the original books.
The most obvious deviation is the gender change of the main character to female. And then, of course, the whole werewolf fandom aspect. In the original series, Harry Potter doesn't have such a specific focus on werewolves. This fanfiction creates a whole new dimension to the character's interests and potentially changes the way she interacts with the wizarding world.
The plot would also be different. Instead of the usual battles against Voldemort and his minions, the focus could be on Harry's interactions with dark creatures. He might be involved in things like trying to improve the living conditions of these creatures in the wizarding world, or trying to integrate them into the wizarding society in a more harmonious way. This is a big departure from the original series' plot which was centered around the fight between good and evil in a more traditional sense.
