In the original Harry Potter series, the focus was more on Harry's battle against Voldemort and the overall wizarding world's fight against the dark forces. In the 'Harry gets Ginny pregnant' fanfiction, the focus shifts to their personal relationship and the implications of the pregnancy. This is a major shift from the main themes of the original books.
The original series doesn't have this plotline at all. In the books, Harry and Ginny get married later in life. So this fanfiction is a big deviation as it jumps to the pregnancy much earlier in their relationship. It's a completely different take on their story.
The original Harry Potter series is about friendship, love, and the fight against evil. Harry is portrayed as a hero who would never harm his loved ones. However, in this fanfiction, the very foundation of Harry's character is shaken. It also changes the overall tone of the story. Instead of a story of hope and heroism, it becomes a dark and tragic tale that subverts the expectations set by the original series.
In the original storyline, Harry and Ginny get married. So in this fanfiction, it's a complete divergence. It might change the whole future of the characters. For example, the Weasley family dynamics would be different without Ginny being Harry's wife. And Harry's own personal development and relationships with other characters would also take a different turn.
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.
Well, in the original series, Harry is a fighter. He always tries to stay alive to fulfill his destiny. But in this fanfiction, his desire to die is a huge deviation. It shows a much darker and more desperate side of him that we don't really see in the original.
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.
The 'Harry and Crookshanks' lemon fanfiction likely deviates from the original series in terms of the nature of the relationship. In the original, the relationship between Harry and Crookshanks was more of a normal pet - owner type. But in the fanfiction, especially with the 'lemon' aspect, it might involve more complex and perhaps inappropriate relationships. Also, the plot might take wilder turns as it's not bound by the original story's constraints.
Well, the original series focuses on themes like magic, friendship, and heroism. 'Dirty talk slash fanfiction' goes way off track as it involves inappropriate content. The original Harry Potter doesn't have any such vulgar elements. It's about the battle between good and evil, the growth of the characters in a magical world, not about dirty talk or non - canon sexualized relationships which are often in this type of fanfiction.
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.
It deviates mainly in the relationship aspect. In the original series, there's no romantic or such intense relationship between Harry and Pomfrey. But in the fanfiction, the 'lemon' element might introduce a romantic or at least a very close relationship. Also, the fanfiction might take Pomfrey out of her normal healer role more often. In the books, she's mostly just in the hospital wing, but here she could be involved in adventures with Harry.
