A plot device that is often used is the discovery of new powers or abilities. When Nightwing turns into a girl, she might find that she has some unexpected powers or enhanced senses that come with this new form. This could be related to a more feminine energy or something unique to the female body in the context of this fictional world. Also, the plot could involve Nightwing's struggle with her own identity. She has to figure out if she's still the same hero or if this new form means she needs to redefine herself, both as a person and as a superhero.
Another is the struggle to maintain the disguise. This can involve things like trying to imitate male behavior, speech patterns, and physical mannerisms. In some fanfictions, the character has to constantly be on guard against accidental reveals, like when changing clothes or during physical activities that could expose their true identity.
One common plot device is the modern girl being a fish out of water in Middle - earth. For example, she might struggle with the different cultural norms and technologies. Another is her forming an unexpected bond with a hobbit or other character. Maybe she shares modern knowledge that helps in a difficult situation, like knowledge of basic first aid that is different from Middle - earth's healing methods. Also, there could be a plot device where she has to hide her true origin to avoid causing chaos or being seen as a sorceress because her modern ways seem so strange to the people of Middle - earth.
One common plot twist could be Zuko, as a girl, having to navigate the same political challenges but with new gender - based obstacles. For example, she might face different expectations in the Fire Nation's patriarchal society. Another could be a romantic sub - plot where characters who previously interacted with male Zuko now have different dynamics with her as a female. Also, Zuko might use her new form to her advantage in disguise, perhaps infiltrating an all - female group to gain information for her cause.
Many 'danny turns into a girl' fanfictions also include a journey of self - discovery. As Danny adjusts to his new form, he starts to learn more about himself and the concept of gender. He might start to question traditional gender norms and find new aspects of his personality that were suppressed before. This could involve things like trying out new hobbies or styles that he was previously hesitant to explore because of his male identity.
Often, Hermione's injury serves as a catalyst for character development. Her own strength and intelligence are put to the test as she has to deal with being injured. She might have to rely on her knowledge of magic in new ways while being incapacitated. And there could be a sub - plot about her relationship with other characters. Maybe she and Ron grow closer as he takes care of her, or she and Harry have deeper conversations about the risks they all face. This all makes for an engaging story.
A really interesting plot twist could be related to Kenny's family. Since his family situation is already quite complex in the show. As a girl, his family might treat him completely differently. His father could become overly protective, or his mother might try to live out her own unfulfilled dreams through Kenny as a girl.
One common theme is friendship. They often start as colleagues or allies and their friendship deepens as they face various challenges together. For example, in many fanfics, they rely on each other's skills during battles.
A frequently used plot device is the protection of the timeline. Hermione, as a Time Lady, has to safeguard the integrity of the wizarding world's timeline from those who would try to change it for their own gain. Also, the idea of alternate timelines can be explored. For example, what if Voldemort won in a different timeline? Hermione might have to travel there and fix things. There could also be plot devices related to her newfound powers clashing with the existing magical order in the wizarding world.
Well, one possible plot could be that Goku, as a girl, has to face different challenges in the martial arts world.
