How does the character of Harry Potter change in 'Harry Potter raised by Voldemort' fanfiction?

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.

He becomes more humble. Elves are used to serving and being in a subservient position. Growing up with them, Harry would learn the value of every being, no matter their status. He'd be less likely to show off his magical abilities like he might have in the original story.

He might become more confident in his pure - blood heritage. Since Dorea Black is from an old pure - blood family, she could instill in Harry a sense of pride and belonging that he didn't have in the original story. This could change his attitude towards other pure - bloods and half - bloods.

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.

He becomes more conflicted. Knowing he's Voldemort's son, he's constantly in turmoil about his true nature. His confidence might waver as he wonders if he's capable of the same evil as his father.

Harry would probably be more attuned to dark magic. His upbringing by Satan would expose him to different forms of magic and he would have a different understanding of power. He might be more ruthless in achieving his goals and less concerned about the consequences for others. For example, in the original series, Harry was always worried about the safety of his friends, but in this fanfiction, he might use his friends as pawns if it served his purpose.

His character becomes more confident. Since he was raised by a god, he has a certain level of self - assurance that normal Harry might not have. He may not be as easily intimidated by Voldemort or other threats.

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.

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.

He'd be more adaptable. Quarians live in a different way than wizards, so Harry would learn to be flexible in new situations.
