Well, in such a fanfic, perhaps Sasuke, now a girl, decides to use this new form to his advantage in espionage. He could infiltrate an enemy group more easily as a female. Also, there could be a really interesting sub - plot where he has to deal with his own self - image and acceptance of this new body. He might initially be in denial but then gradually come to terms with it.
In addition to the obvious ones like Naruto and Sakura, other characters from Sasuke's clan might interact with him. For instance, if there are any remaining Uchiha members, they might have mixed reactions. Some could be shocked and try to figure out what happened, while others might be more accepting. Also, characters like Shikamaru, who is very observant, would surely notice the change in Sasuke and might have some unique interactions, perhaps trying to figure out how this change could affect their team dynamics or the overall situation in the village.
His character development would likely be more focused on emotional aspects. As a girl, he might be more in touch with his feelings and less likely to bottle them up. For example, instead of being so stoic all the time, he could show more vulnerability.
Maybe Naruto was trying to protect Sasuke from a certain danger. There could be a curse or a powerful enemy that targets male shinobi. So, Naruto uses a risky jutsu to transform Sasuke into a girl to keep him safe. Or it could be that Naruto found a strange ancient scroll with a transformation technique that he thought was something else and when he used it on Sasuke, it turned him into a girl.
Well, perhaps a plotline could involve Sasuke turning into a girl and using this new form to his advantage in some undercover mission. He could infiltrate an enemy group more easily as a girl. Also, there could be a love triangle where some of the characters who previously saw Sasuke as a male now have different feelings towards him as a girl, which would create a lot of drama and conflict.
No. Writing such content involving underage characters in sexual situations is completely inappropriate and unethical. It violates moral and ethical standards as well as many laws regarding the protection of minors.
Well, it has multiple negative impacts. Firstly, it goes against the moral obligation to protect minors from being sexualized. Secondly, it can damage the reputation of the original work and its fandom. People who come across such inappropriate fanfic may form a negative view of the whole franchise. Thirdly, it can have a negative influence on the mental health of those who are exposed to it, especially young and impressionable fans.
Sasuke would be completely shattered. His world would be turned upside down. He had always seen Naruto as a rival, but also as someone important. Naruto sacrificing himself for him would make Sasuke reevaluate his entire life. He would feel an overwhelming sense of guilt and would likely isolate himself from others. However, over time, he would start to use Naruto's sacrifice as a motivation to become a better person and to protect the things Naruto held dear. He would start to follow in Naruto's footsteps in terms of values like friendship and loyalty, and would try to make amends for his past mistakes.
I don't think it's a common trope. Naruto has a large and diverse fan base, and most of the fanfics are centered around the core themes of the series, such as the ninja world, the power struggles, and the bonds between the characters. While there are some fanfics that might explore the romantic and sexual aspects of the characters' relationships, this particular scenario seems rather out of place and not in line with the general tone of most Naruto fanfics.
Well, the plot could start with the twins finding some sort of magical object or spell that they think would be hilarious to use on Harry. Once they turn him into a girl, Harry might be initially shocked and confused. He could then have to deal with the reactions of his friends like Ron and Hermione. Ron might be really surprised and a bit clumsy in his interactions at first. Hermione could be more practical, trying to find a way to reverse the spell. And all the while, Harry (as a girl) might discover new things about himself and the way others perceive him.
