If Harry is a centaur, it adds a whole new layer of wisdom and a different perspective on magic. Centaurs in the Potter world are known for their knowledge of astronomy and prophecy. So Harry as a centaur would bring in that knowledge and perhaps be able to foresee events more accurately. It also changes his physical form and how he interacts with other characters. He might be more at home in the Forbidden Forest rather than the Gryffindor common room.
These fanfictions can change the relationships between characters. If a character is made into a goddess, the way other characters interact with her will be different. For instance, if Harry has to seek help from a goddess - like Hermione, their friendship might take on a more formal or reverential tone. Also, new magical concepts are introduced. A goddess might have the power to manipulate time in a way that's not in the original books, which then creates new plot possibilities.
In 'Harry Potter travels fanfiction', new locations are often added. For example, Harry might travel to a hidden valley full of ancient magic that was never mentioned in the original books. It also adds new magical creatures. He could encounter a species that's unique to the place he travels to. New spells and magic systems can be introduced too. When he travels to a different wizarding culture, their way of using magic might be completely different from what he's used to at Hogwarts.
It adds the element of a medical condition. Narcolepsy makes Harry more vulnerable and gives him a different kind of challenge compared to the usual ones in the original story like fighting Voldemort. It can also change the dynamics of his relationships. For instance, some fanfictions show that his teachers might be more lenient or more strict because of his narcolepsy.
The 'dominant creature' concept adds a new layer of excitement. It can introduce new powers and abilities. For example, if Harry has a dominant magical creature by his side, like a griffin, it can change the way battles are fought. It makes the story more unpredictable.
The concept of pestilence adds a new level of danger and drama. In the normal Harry Potter world, there are already threats like Voldemort and dark wizards. But pestilence is something that can affect everyone, regardless of their magical abilities or allegiances. It can create a sense of panic and chaos, which is different from the more targeted attacks in the original series.
In this kind of fanfiction, creature inheritance often works through family bloodlines. If a family has a long - ago connection to a certain creature, like an ancestor who made a pact with a unicorn, that connection might be passed down generations. It could also be triggered by a magical event. For instance, if a character is in a place where a powerful magical creature once lived and a magical energy is released, it could awaken the inheritance.
It adds a new cultural aspect. The original series is mainly set in a Western European - inspired wizarding world. 'Harry Potter Jewish fanfiction' brings in Jewish culture, which has a rich history and traditions. This can include different values, like the importance of family and community in Judaism, which can be reflected in the relationships between characters in the fanfiction.
It adds variety. The different creatures make the world of Harry Potter more diverse. For example, the presence of house - elves gives a different perspective on the social structure in the wizarding world. They are not just there for decoration but play important roles in the story, like Dobby who helps Harry at crucial times.
If the creature is a gentle and wise one like a unicorn, it could enhance Harry Potter's sense of purity and goodness. The unicorn's grace and magical essence might inspire her to be more in tune with the positive aspects of magic. For example, she might become more empathetic towards other magical creatures.
In Harry Potter fanfiction, creature inheritance often varies. Sometimes it can be a hidden trait passed down through families. For example, a character might inherit werewolf genes from a distant relative. It could also be related to magical abilities that are specific to certain magical creatures, like the ability to communicate with snakes if there's some sort of serpent - related inheritance. Usually, it adds an extra layer of mystery and power to the characters in the fanfiction.
