Well, if Levi turns into a girl in the fanfiction, his fashion sense could be an interesting aspect. Maybe he would start wearing different types of gear. Instead of his usual plain style, he could end up with something more stylish yet practical. Also, his interactions with female characters would take on a whole new dimension. He might be able to better understand the struggles that female soldiers face in the Survey Corps. This could lead to him advocating for more equality within the military ranks.
Perhaps Levi, as a girl, would have a different emotional side. In the original, he was quite stoic, but now he could show more vulnerability. This could make his character more relatable to the other characters. His leadership style might also change. He could become more nurturing, while still maintaining his strict discipline. His transformation could also attract unwanted attention from some male characters, which could lead to some tense or comical situations within the story.
Well, one possibility is that he'd have to deal with all the social norms and expectations that come with being a girl in his world. Maybe he'd be shocked by how differently people treat him. For example, his male friends might be more protective or act differently around him. Also, he could discover new things about himself, like a different sense of fashion or a newfound interest in activities typically associated with girls.
One possible plot twist could be how his relationships change. For example, his friends might react with shock and confusion at first. Mikasa might have a whole new set of emotions to deal with, like a different kind of protectiveness. Also, the military might view him differently. They could be hesitant to send a 'female - Eren' into battle at first, or they might use his new form to their advantage in different ways, like using his appearance to deceive the Titans.
One possibility is that his relationships with other characters would change drastically. For example, his interactions with Saber might become more complex, perhaps evolving from a more traditional male - female dynamic to a more nuanced friendship or rivalry. His friends like Rin might also be very surprised at first but then gradually accept this new version of him. And in battles, his fighting style might be affected as well, since his physical form is different now.
In terms of the story's development, it could lead to a whole new arc. Naruto's transformation into a baby girl could be a sign of a greater threat to the ninja world. It might be related to some ancient curse or a new enemy's plot. And as he tries to figure out how to turn back, he would have to rely on his friends and his own inner strength in a different way than before.
His role in the Survey Corps might change in terms of the tasks he's assigned. He could be used more for intelligence - gathering missions that require a different kind of approach. Since he's now a girl, he might be able to infiltrate certain areas more easily where male soldiers would draw too much attention.
Well, it could involve a quiz where the reader has to make choices related to their interactions with Neko Levi in the Attack on Titan world. For example, choosing how to respond to Levi in a dangerous situation might lead to different story branches.
She might find herself in the middle of the battle against Titans. Maybe she uses her modern knowledge, like basic first aid or some scientific concepts, to help the characters in the fanfiction.
In a fanfiction where Luffy turns into a girl, the story could take an interesting turn. Luffy's dreams of becoming the Pirate King wouldn't change, but the way he approaches it might. As a girl, he could use his charm to get out of some tricky situations. For example, when dealing with some of the more traditional pirates or marines who might underestimate a girl. Also, the Straw Hat crew's dynamic would shift. Zoro might be more protective, not that he isn't already, but in a different way. And Chopper would be super curious about the sudden change and would constantly be checking if there are any medical reasons for it, even though it's a magical fanfiction change.
Well, one possibility is that Naruto, now as a girl, might face new challenges in the ninja world. People could underestimate her at first, but she would soon prove them wrong with her skills. Maybe she would also develop new relationships. For example, her friendships with Sasuke and Sakura could change in interesting ways. She might have to deal with different expectations from her peers and sensei.
Well, one thing that could happen is that Drake would have to deal with all the new social expectations. For example, he might be expected to act more demure or ladylike. His relationships with his friends, especially Josh, would also change. Josh might feel protective in a different way. Maybe Drake would start to notice how differently people treat him as a girl, like getting different reactions when trying to join in on all - boy activities. And he could use this new perspective to understand the girls around him better, leading to some really interesting and comical situations in the story.
