The original story has a strong theme of self - sacrifice and heroism. In the fanfiction where they are related, this could be altered. Harry might struggle more with the idea of having a connection to Voldemort. It could add a layer of internal conflict, as he wonders if he has some of Voldemort's darker tendencies within him. This could change the theme from a straightforward battle of good against evil to a more complex exploration of nature vs. nurture. Harry has to decide whether his relation to Voldemort defines him or if he can rise above it and still be the hero we know from the original story.
Well, it changes it drastically. In the original, Harry is the hero against Voldemort. But in this fanfiction, the dynamic is completely different. Harry's abuse gives him a different background and the revelation of his relation to Voldemort makes him an outcast in a new way.
Harry could become more powerful in a way that scares his friends. Voldemort's training might focus on the Dark Arts, which are powerful but dangerous. This could change Harry's magic style. He may become more solitary as his new skills and knowledge set him apart from his Hogwarts friends who follow a more traditional path of magic.
Well, it can change the themes of friendship. For example, if Harry was a girl, the way she interacts with Ron and Hermione might be different in terms of the traditional male - female friendship dynamics. It could also impact the theme of heroism. A female hero in the 'Harry Potter' universe might face different challenges compared to a male hero, like different expectations from society within the wizarding world.
Harry in this fanfiction is likely to be more ruthless. Voldemort's upbringing would make him less empathetic. He may value power above all else and be more willing to use dark magic to achieve his goals. His relationships would also be different. He wouldn't have the same close - knit group of friends as in the original story. Instead, he might be surrounded by Death Eaters or those who follow Voldemort's ideology.
It changes the canon by introducing a new form of interaction between Voldemort and Harry. Instead of just the typical battles and mind - reading attempts we see in the original books, the 'plugging' concept adds a more invasive and direct connection. For example, Voldemort could directly influence Harry's thoughts and actions in ways that were not possible in the canon.
Well, in such a fanfiction, it could completely flip their relationship. Maybe Harry realizes that Voldemort has some hidden motives that are not entirely about killing him. It might be that Voldemort sees some value in Harry that he wants to use for his own gain, rather than just destroying him like in the original story.
Well, it might make him more cynical at first. After all, he has just absorbed the essence of the most evil wizard. But then he could use this newfound darkness within him to better understand the bad in the wizarding world and fight it more effectively.
In these fanfictions, Harry's character transformation is quite drastic. He loses his sense of morality. His loyalty, which was once towards his friends and the good side, now shifts to Voldemort. He becomes more power - hungry, willing to do whatever it takes to gain more power, including using dark magic without hesitation. He also becomes more secretive and manipulative, using his former relationships to further Voldemort's goals.
In fanfiction, Harry Potter and Voldemort are related through the prophecy that ties their fates together. This often leads to scenarios where Harry has a unique understanding of Voldemort, like being able to see into his mind. Fanfic writers may also play with the idea of a shared past or some sort of magical bond that was created before they even knew of each other. They are two sides of a magical coin in many fanfictions, with Harry representing the good and Voldemort the evil, but their relationship is much more nuanced than just that.
If Harry Potter was Voldemort's son in fanfiction, it would completely change the story. Firstly, the relationship between Harry and Voldemort would be extremely complex. Instead of being arch - enemies, there would be a strange family bond. Harry might struggle with his identity more. He would have to deal with the fact that his father is the most evil wizard. The Hogwarts faculty might also treat him differently. They would be more suspicious of him and his motives, fearing that he might inherit Voldemort's evil ways. Also, his friends might have a hard time accepting this new truth about him.
