A plot twist could be that the transformation into a girl makes Spiderman lose some of his traditional powers but gain new ones. For instance, instead of his usual web - slinging ability, he could have the power to manipulate plant life to his advantage. This would completely change the way he approaches fighting crime and protecting the city.
A plot twist could be that Midoriya's transformation into a girl is not permanent, but she doesn't know how long it will last. This uncertainty could create a lot of internal conflict for her. She might be worried about how long she'll be in this form and how it will impact her long - term goals as a hero. Also, it could be that in this form, she discovers new aspects of her quirk that she was previously unaware of, but these new abilities come with a price. Maybe using them in this female form drains her energy faster or has some other negative side - effects.
One possible plot twist could be Percy's struggle to adapt to the new gender. For example, she might face challenges in how society now treats her. Maybe she was used to certain privileges as a boy that are now different. Another twist could be in her relationships. Her friends might react in various ways, some being very accepting while others are confused or even distant at first. And she could also discover new aspects of herself, like different interests or ways of expressing emotions that were suppressed before.
In the fanfic, perhaps Goku's transformation into a girl is the result of a magical spell. As a girl, she might start to see the world from a different perspective. She could be more in touch with her emotions and this could either enhance or hinder her fighting abilities. For instance, she might be more empathetic towards her enemies, which could lead to some interesting moral dilemmas during fights. Her training regime might also change as she adapts to her new body.
One possible plot twist could be that Sasuke, now as a girl, has a different perspective on his past actions. Maybe he becomes more empathetic towards Naruto's ideals of peace.

Also, it could lead to some interesting romantic sub - plots, perhaps with Naruto or other characters having new feelings for Sasuke in this new form.
One possible plot twist could be that Naruto, while in his Kyubi form, loses control completely and starts to attack his friends. This would create a huge internal conflict for him when he comes back to his senses. Another could be that his transformation into the Kyubi gives him new abilities that are not related to just brute strength, like the power to communicate with other ancient beasts. Also, perhaps the transformation is not permanent, but rather fluctuates based on his emotions, leading to some really tense moments during battles or important interactions.
One possible plot twist could be that as Spider - Man turns into a girl, he (now she) has to deal with different social expectations. For example, the male - dominated superhero world might react differently to a female version of Spider - Man. Maybe she would face more scrutiny or different types of challenges from the media or other superheroes. Another aspect could be her relationships. Peter Parker's friends and family might have a hard time adjusting to the change, and his romantic interests could take a whole new turn. For instance, his previous female friends might see him in a new light, or he might attract different kinds of admirers as a girl. Also, the way she uses her powers could change. Maybe she would be more graceful or use her femininity in combat in a way that's different from the traditional male Spider - Man.
Well, perhaps the plot could involve Luffy having to navigate a world where he is suddenly a girl. He might face challenges in how his friends perceive him now. Maybe he has to deal with different social expectations while still maintaining his goal of finding the One Piece. For example, some of his male friends might be overly protective or act a bit differently around him, and he has to figure out how to handle those new dynamics all while being in a female body.
Well, one possibility is that John, as a girl, might have a whole new perspective on his relationships. He could see his friends in a different light, especially his male friends. Maybe there would be some comical moments as he adjusts to his new body, like trying to figure out new clothing styles. He might also face some challenges in terms of how others perceive him now. For example, some characters might initially be confused or act differently towards him.
Well, in a 'freed turns into a girl' fanfic, the plot might start with an experiment gone wrong. Freed was perhaps trying to enhance his magic power and something in the experiment caused his physical form to change to that of a girl. He would have to deal with the reactions of his guildmates. Some might tease him, while others would be more understanding. And he would also face challenges like how to adapt to the new body's physical limitations while still being able to participate in guild activities.
Well, one possible plot could be that Deku accidentally drinks a strange potion created by a villain. This potion has the side - effect of changing his gender to female. At first, he's shocked and confused. But then, he realizes that he can use this new form to his advantage in hero work. For example, he might be able to infiltrate a female - only villain group more easily. He also has to deal with his friends' reactions, some are surprised while others are supportive and help him adjust to his new body while still being a hero.
