Hermione would be a very likely character to support Harry. She's his best friend and is always there for him in the original story. Ron too, as they are a trio. Neville could also step up, as he has his own growth arc and could understand Harry's feeling of being alone to some extent.
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 possible plotline could be Harry feeling extremely lost and alone at first. He might have to find a new place to live, perhaps with the help of his friends like Ron and Hermione. He could struggle with self - worth, constantly wondering what he did wrong to make his parents disown him.
Well, it could be that Harry ends up in a new magical community that accepts him for who he is, away from the shadow of his disowning parents. He might learn new types of magic that were not taught in his previous life with his family. He could also meet a mentor figure who helps him through the tough times. And then, he might use his new - found knowledge and skills to face his parents again, but this time with confidence and self - assurance.
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.
Harry would likely become more self - reliant. Without the support of his parents, he'd have to learn to take care of himself. He might grow more cautious and distrustful, especially if he doesn't know the real reason for the disownment.
They might rely on their friends a great deal. Harry has a strong group of friends like Ron and Hermione, and Ginny also has her own friends. These friends could provide emotional support, a place to stay, and help them get back on their feet. They may also focus on their own careers or magical studies to distract themselves from the pain of being disowned.
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 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.
Definitely Hermione. She would be the one to encourage Harry to keep going and not let his parents' disowning define him. Neville could also be a great support. He has his own experiences of being underestimated, and he could share his strength with Harry. And Luna. Her unique perspective on life and magic could give Harry new ways to think about his situation, and she would offer him her unwavering friendship.
