One possible fanfiction could be about Petunia discovering her latent witch powers later in life. Maybe she stumbles upon an old family heirloom that unlocks her magical abilities. This could lead to a whole new dynamic in her relationship with Harry, as she now understands the world he belongs to on a deeper level.
One possible fanfiction could be about Aunt Petunia discovering her latent witch powers late in life. Maybe she starts having strange dreams that lead her to an old family heirloom that unlocks her magical abilities. She then has to deal with the shock of it all while also trying to keep it a secret from the Muggle world around her.
One possibility is that Petunia could use her witch powers to protect Harry secretly. Maybe she has a change of heart after years of resentment. She could have been in contact with the wizarding world all along, but hid it from everyone. This would add a whole new layer of mystery and family drama to the Harry Potter universe.
The plot could involve Petunia using her witch powers to protect Harry from the Dursleys' abuse. She realizes that she has a responsibility towards her sister's son and uses her magic to create a safe haven for him within the Dursley household. This would be a big change from her original character who was so against magic.
If Petunia was a witch, it would completely change Harry's upbringing. He might have learned magic from her instead of being in the dark until he received his Hogwarts letter. This would make him more confident and perhaps less of an outcast in the Muggle world.
Perhaps Aunt Petunia is a witch who was cursed long ago. The curse made her forget her magic and act like a Muggle. When Harry unknowingly breaks the curse, she suddenly has her powers back. She then has to face the wizarding world again and deal with all the changes that have occurred since she last remembered her true self. She might even have some unique powers that are different from the norm because of the curse.
One great Petunia fanfiction could be one where she has a moment of self - realization. Maybe she discovers some of Lily's old magic things and starts to understand the wizarding world better. It could show her in a more sympathetic light, perhaps she even tries to protect Harry in her own way.
In the world of 'Harry Potter' fanfiction, most writers tend to stay within the boundaries of the original story's spirit. The concept of Harry Potter impregnating Petunia is so far - fetched and inappropriate that it is highly unlikely to be a part of any well - regarded fanfiction. Fanfiction usually focuses on exploring relationships that are more in line with the potential of the characters as presented in the original, like friendships, romantic relationships among peers, or the growth of the characters within the magical world.
Well, it depends on your definition of 'good'. Some might focus on the complex relationship between Petunia and the magical world in the context of Harry Potter, while others might take a more creative or off - beat approach. You really have to dig through different works to find one that suits your taste. There could be some that explore Petunia's character in depth, perhaps showing her envy of the wizarding world in a new light, or creating a scenario where she has a more positive interaction with the magical elements, which could be quite interesting to read.
It's inappropriate. The Harry Potter series is mainly aimed at a wide range of audiences, including young readers. Lemon fanfiction strays far from the family - friendly and magical essence of the original. Petunia, as part of the Muggle world related to the story, should uphold a certain standard, and using such fanfiction is not in line with that.
