Well, often in such fanfiction, the change might lead to new relationship dynamics. Sasuke as a girl could have different interactions with Naruto, for example. Maybe there would be more emotional and less combative exchanges at first. The story could explore how Sasuke deals with this new form and the reactions of other characters in the Naruto universe like Sakura, who might be jealous or more protective.
In these kinds of fanfictions, the plot might revolve around Sasuke trying to find a way to change back. Kyuubi's motives for turning Sasuke into a girl could also be a major part of the story. It could be a prank, or maybe there's some deeper, more mysterious reason. And Sasuke's new appearance might attract unwanted attention from villains who see her as an easier target or something more valuable in this new form.
Well, usually it starts with Naruto using some sort of jutsu or magic (in the fanfic world). Then Sasuke suddenly finds himself in a female body. At first, he might be really confused and angry. But as the story goes on, he starts to experience things differently as a girl. For example, he might notice how people treat him differently. Naruto might also start to see Sasuke in a new light, and there could be some really interesting character development and new relationships forming between them.
A common theme is identity crisis. Sasuke suddenly being a girl would make him/her question who they are now. Another theme could be acceptance, both from Sasuke herself and from the other characters. Also, there might be a theme of newfound friendship. As a girl, Sasuke might make new friends that he wouldn't have made before.
Well, in some versions, it might start with the fem Kyuubi having some sort of vendetta against Naruto. Maybe she blames him for something that happened in the Naruto universe. Then she uses her powers to torture him in various ways, like mental torture by showing him his worst fears or physical torture by using her chakra in a harmful way. However, this is all very dark and not in line with the general positive theme of the Naruto series.
In fanfictions where this happens, the development can vary widely. One common way is that Naruto's transformation into the Kyuubi causes a rift in the ninja world. Some villages might see it as an opportunity to attack Konoha while it's dealing with this internal crisis. Meanwhile, Naruto himself is trying to regain his humanity. His friends, especially those closest to him like Kakashi and Iruka, would be determined to help him. They might have to face their own fears and prejudices towards the Kyuubi as they try to reach Naruto. There could also be a sub - plot where other jinchuriki are involved, either to help or hinder Naruto's situation.
Well, first of all, there's the initial discovery of Snape as a baby. This causes a stir in the wizarding world. His enemies might see it as an opportunity to take advantage, while his friends (if he has any left in this state) will try to protect him. As the story progresses, there could be attempts to communicate with baby Snape, who may or may not retain some of his adult memories or magical abilities. The plot could then revolve around finding a cure, which could involve dangerous quests, ancient spells, or encounters with mysterious magical creatures. It's a really rich area for fanfiction writers to explore different aspects of the Harry Potter universe through this unique transformation.
Often, it starts with Sasuke realizing her feelings for Naruto in a new light because she's a girl. She might be more in touch with her emotions. Then, there could be a lot of blushing and shy moments between them. For example, Sasuke might struggle to hide her love while still trying to be a strong ninja. As the story progresses, they might start to work together more closely, and Sasuke's love could motivate her to protect Naruto even more.
Often, she might be turned back into a human. Maybe a kind wizard or a magical spell reverses the transformation.
Well, in some fanfictions, it often starts with Draco using a spell or a potion on Harry. Then, Harry has to deal with the sudden change. He might struggle with his new identity at first. For example, he could be confused about how to act as a girl in the wizarding world. There could be a lot of humorous situations, like when he tries on girl's robes for the first time and doesn't know how to walk in them properly. Also, his friends might have different reactions. Hermione could be more empathetic and try to help him adjust, while Ron might be completely bewildered.
She could also change in how she approaches relationships. Before, as a boy, Sasuke was more reserved in his interactions with others, especially with Naruto. But as a girl, she might be more forward in expressing her feelings towards Naruto, whether it's friendship or something more. This could lead to some really interesting character development arcs and new plot directions in the fanfiction.
Fanfiction usually develops Anakin's character by showing his relationships in a new light. His bond with Palpatine could be shown as more complex, with Palpatine slowly manipulating Anakin over a long period, preying on his weaknesses like his desire for power to save Padmé. This makes his turn seem more gradual and believable.
