Perhaps Harry is disowned because his parents believe he has been corrupted by dark magic. So he has to prove his innocence and find a way to reverse their decision. Along the way, he meets a mentor who helps him master his magic in a new and unique way, different from what he would have learned from his parents.
In a fanfiction about Harry Potter and his parents, a great plot could be that Harry discovers a hidden diary of his mother. Through reading it, he gets to know her deepest thoughts, her fears, and her hopes. He also learns about the early days of the Order of the Phoenix through her eyes. This discovery could change his perspective on his own life and his place in the wizarding world. He might then be inspired to follow in his parents' footsteps more closely, perhaps by joining an organization that his parents were once part of.
One plotline could be Harry finding a new family among his friends at Hogwarts. They become his support system and help him grow in ways his biological parents couldn't. Another could be Harry's journey to discover why his parents disowned him and uncovering some dark family secret along the way.
One popular 'Fem Harry Potter Disowned by Parents' fanfiction is 'The Lost Potter'. It really delves into how a female Harry would cope with such a harsh situation. She has to find her own way in the wizarding world without the support of her family. Another great one could be 'Abandoned by Blood' which shows her journey of self - discovery while facing the challenges of being disowned. It's interesting to see how the author portrays her building new relationships and finding her true power.
She often then becomes determined. She realizes she has to rely on herself. So, she starts to explore her magic more independently. In some fanfictions, she might begin to study in secret or practice spells on her own to become stronger. She also might look for new allies, like other outcasts in the wizarding world. This could include befriending house - elves or half - bloods who have also faced discrimination. As she progresses, she can become a very strong and independent character, using her past pain as motivation to succeed.
One possible reason could be a misunderstanding. Maybe he discovers some secrets about his parents that he misinterprets. For example, if he finds out they were involved in some dangerous or morally ambiguous activities in their youth that he doesn't fully understand at first.
One possible plot could be that Harry, after years of feeling unappreciated or burdened by his fame in the wizarding world, decides to disown himself. He might leave Hogwarts and the wizarding community behind, perhaps to live as a Muggle. He could change his identity and start a new life, away from the constant danger and expectations that come with being Harry Potter.
In a fanfiction where Harry's parents are alive, it could be that they were secretly protected by a powerful ancient magic. They were transported to a different magical realm. When they return, they bring with them new magical knowledge and spells. They help Harry become an even more powerful wizard. For example, they teach him how to combine different types of magic in unique ways. They also work to improve the relations between the wizarding world and other magical creatures.
Well, a common concept is that Harry's real parents were actually involved in a prophecy that was much more complex than the one we know. Maybe they were trying to prevent a greater evil than Voldemort, and in the process, they had to make sacrifices that led to their seeming deaths. For example, they could have faked their deaths to go into hiding and protect Harry in a more covert way.
Well, it completely flips the typical relationship dynamic. Usually, Harry idolizes his parents. But in this fanfiction, by disowning them, it creates a sense of conflict and chaos. It might make the story darker as Harry is now sort of an outcast not just in the wizarding world in general but also from his own family legacy.
Harry would likely be more cynical. Without the love and support of his parents, he'd grow up feeling abandoned. He might be more distrustful of others, especially those who claim to be helping him. For example, he might not trust Dumbledore as easily as in the original story.
