The original series is very Hogwarts - centric. But in a fanfic with Kyoya's fiance, the story could be set in different magical locations around the world. Her character could be the reason for exploring places like the wizarding schools in Japan or some hidden magical islands. It would give a whole new perspective to the Harry Potter universe, showing different cultures and magics that we haven't seen much in the original books.
The 'harry potter is royalty fanfic' will probably have a different social structure. The original series had a clear structure based on blood status in the wizarding world (pure - blood, half - blood, muggle - born). In the fanfic, there will be an added layer of royalty. This means that there could be new forms of discrimination or privilege based on royal blood as well as magic blood. There could also be new types of magic associated with royalty, like magic that is only accessible to those of royal bloodline, which is a significant departure from the original series.

The main difference is the concept of oath - breaking. In the original series, loyalty and oaths are important but not explored in this 'oathbreaker' way. In the fanfic, characters might take actions that go against their previous commitments, which is a big deviation.
It differs in many ways. In the original series, the story follows a set path, but in 'defiance harry potter fanfic', the author can take more liberties. For example, the fanfic might change the alliances or the motives of the characters. Maybe some characters who were enemies in the original become friends in the fanfic.
The main difference is her identity. In the original, Harry is a white male, but in this fanfiction, being a Black female completely changes her experiences. For example, she may face more prejudice in the wizarding world right from the start. In the original, Harry had to deal with the fact that he was an orphan and the chosen one, but here, on top of that, she has to deal with racial issues. Her relationships will be different too. The way she interacts with Draco Malfoy, for instance, might be more complex as he may be even more of a bully due to her race. And the way the teachers treat her could also vary. Some teachers might have unconscious biases that she has to overcome.
In the original Harry Potter series, Harry is mainly dealing with the threats from Voldemort and his followers. However, in Monster Harry fanfic, the focus shifts to his interactions with monsters. For example, he may have to form alliances with them or fight against them in ways that are not present in the original story.
The original 'Harry Potter' series mainly follows the established order of the wizarding world, with Harry and his friends fighting within the framework of Hogwarts and the Ministry. But 'Harry Potter vigilante fanfic' often break these rules. They might have the characters acting outside the law to achieve their goals.
Well, the original Harry Potter series is mainly about good versus evil, with Harry as the hero fighting for the greater good. However, in a mercenary fanfic, the focus is on Harry as a sort of lone wolf, using his magic skills for his own benefit. In the original, the magic is often used for defense and to uphold the values of the wizarding world. In a mercenary fanfic, magic can be a tool for Harry to gain an edge in his mercenary gigs. He might use spells in more unorthodox ways to complete tasks that are not related to the typical wizarding world problems. Also, the setting might expand beyond Hogwarts and the familiar wizarding locations as Harry takes on jobs all over the magical realm.
The 'harry potter revolution fanfic' differs mainly in the plot. While the original series focuses on Harry's fight against Voldemort, the fanfic may center around a revolution in the wizarding world. It could have different villains or challenges. Also, the character relationships might change. In the fanfic, some characters who were allies in the original might be at odds, and new alliances could be formed.
In the original series, Harry isn't a seer. So, this fanfic changes that fundamental aspect. It could lead to different interactions with characters like Trelawney, as he now shares a similar power.
