Yes, it is possible in fanfiction. The key is to re - imagine the backstories of Albus, Minerva and Hermione. For example, the author could write that Albus and Minerva were young lovers before they became the well - known Hogwarts professors. And then Hermione could be their magically gifted daughter. It would require a lot of creativity to blend their different personalities and the existing 'Harry Potter' lore.
In fanfiction, the author has the liberty to create all kinds of relationships. It could be that the fanfiction is set in an alternate universe where the normal rules of the Harry Potter series don't apply. So, Hermione could be Albus's daughter due to some new magical laws or circumstances created by the author. For example, a new magic that allows for the creation of family bonds in unusual ways.
Well, in such fanfiction, a common theme is the re - imagining of the wizarding world's social norms. Since Albus and Minerva having a daughter like Hermione is not part of the original story, it challenges the existing social order in the wizarding community. Another theme could be Hermione's journey to discover her true self. She may face discrimination or disbelief from others due to her unique parentage. And of course, there could be a theme of family bonds, how Albus, Minerva and Hermione support and love each other despite the odds.
One possible main plotline could be how Albus and Minerva adjust their lives to take in Hermione. They might face challenges from the wizarding community who question their decision. For example, some might think Hermione is too Muggle - born for such a prominent magical family. But Albus and Minerva would be determined to give her a loving home. They would help her grow not only in her magical abilities but also in her confidence and understanding of the wizarding world at a deeper level.
In fanfiction, it's possible through creative interpretations. Writers might use magic as a means. For example, they could create a unique spell that allows two female characters to have a child. It could also be a result of some magical artifact that has the power to make this happen. Another way could be through a magical bond that transcends normal biological limitations.
One interesting plot could be how Hermione adjusts to her new family life with Minerva and Albus. Maybe she starts to learn different magical skills from them in a more personalized way compared to at Hogwarts.
Hermione would likely develop more confidence in her magical abilities. With Albus and Minerva as her guardians, she would have access to a wealth of knowledge and guidance. This could make her less hesitant in using magic in new and untested ways. For example, she might be more willing to experiment with spells she reads about in old books, knowing she has the support of two of the most powerful wizards at Hogwarts.
Minerva would be a strict but loving mother - figure. She would be very protective of Hermione and would use her wisdom to guide Hermione in her magical studies and in life. She might be a bit more relaxed in her personal interactions with Hermione compared to how she is with students at Hogwarts.
Well, it could change a great deal. For one, Hermione might have had access to more knowledge and magic earlier. Minerva could have secretly trained her, giving her an edge in her studies. This could also change her relationship with Harry and Ron. Maybe she would be more cautious about getting into dangerous situations as she wouldn't want to disappoint her mother.
In this type of fanfiction, it could be possible through some dark magic or a hidden plot twist. Maybe a spell was cast long ago that altered the truth about Hermione's parentage. However, it goes completely against the original story's lore.
In fanfiction, anything can be possible. Maybe the author created a unique backstory where Hermione is the Doctor's daughter through some sort of time - travel or alternate universe scenario. For example, in a time - warped dimension, the Doctor could have had a relationship that led to Hermione's birth. It's all about the creativity of the fanfiction writer.
