One possible plot could be that Peter Parker, now as a girl, struggles to adapt to the new physical form while still trying to keep up with her superhero duties. She might face different challenges in terms of how society perceives her new identity and how she interacts with her friends and enemies. For example, her male friends might initially be confused or act differently around her. And she could discover new powers or abilities related to her new form as well.
In a Peter Parker turned into a girl fanfic, the plot might center around her trying to hide her new form from certain people like Aunt May at first. As she continues to be Spider - Girl, she could face unique challenges in school. For instance, she might have to deal with different kinds of bullying or jealousy from other students.

One plot development could be the reaction of the Avengers or other superheroes to Peter's transformation. They might be initially confused or even skeptical about whether it's really Peter. And Peter, as a girl, would have to prove herself all over again in the superhero community. There could also be a plot where she discovers new powers or abilities that come with her new form. This could lead to her being more of an enigma in the superhero world and having to figure out how to control these new powers while still maintaining her identity as Peter Parker at heart.
Her powers might not change much in terms of strength and agility. However, the way she uses them could be different. For example, she might be more flexible in her movements as a girl, which could enhance her acrobatic abilities while swinging from building to building. Also, her spider - sense could be more attuned to different threats, like threats that are more specific to female superheroes such as certain types of harassment or discrimination.
In a fanfic plot, perhaps there is a scientific experiment gone wrong that affects both Ava Ayala and Peter Parker.

There could be some romantic undertones as they rely on each other more and more, and they might have to make sacrifices to save the day and each other.
In a Peter Parker Hunger Games fanfic, perhaps the Capitol has a special interest in him because of his powers. They might want to see how a super - powered individual fares in the Hunger Games.

Well, perhaps Peter Parker teaches Harry about the value of secrecy. Since Peter has to keep his identity as Spider - Man a secret, he could pass on that wisdom to Harry. Also, he could teach Harry some acrobatic skills which are useful in combat situations. Peter might use his own life experiences to mentor Harry in making moral choices.
His personality might become more in touch with his emotions. As a girl, Peter could be more empathetic and sensitive. He might also be more cautious in some situations, as society often treats girls differently. For example, he might not be as quick to jump into a fight without thinking about the consequences more carefully.
Well, perhaps in the fanfic, a magic spell gone wrong turns Harry into a girl. He then discovers that being a girl in the wizarding world gives him a whole new perspective.

For example, his relationship with Ginny could become more of a sisterly bond at first as he adjusts to his new form.
