One main character that often interacts with 'madara as a girl' in fanfictions is Hashirama. Their relationship could be completely transformed. Instead of the male - to - male rivalry and friendship, it could be a more nuanced relationship. Hashirama might be more chivalrous towards her, or she could use her charm to manipulate him in some way. And other minor characters from the village might also interact with her, like the shopkeepers or the children, which could show different aspects of her character.
Well, it depends on the specific fanfiction. But it could be Naruto. Their interactions would be really different from the original. Maybe Naruto would be more protective of her or have a different kind of friendship. Another character could be Sasuke. They might have a more complex relationship, perhaps with some romantic undertones if the fanfiction takes that route.
In a fanfiction, Madara might initially be dismissive of Sakura. But as she shows her strength and intelligence, especially when it comes to the significance of the lemon (maybe it has some sort of magical or medicinal property), he starts to respect her. Sakura, on the other hand, would be cautious around Madara due to his reputation, but she also sees the potential in him to help with whatever task involves the lemon. The lemon could be a catalyst for their interactions, like they have to protect it together or figure out its secrets.
Sasuke could be a main character as well. Given his own experiences of being an outcast and having a thirst for power at times, he could relate to Madara in some ways. They might form an unexpected alliance or have a rivalry based on their shared experiences of feeling neglected or misunderstood in the ninja world.
Among the students, Hermione Granger - if we consider a scenario where this fanfiction has some sort of time - travel or alternate universe aspect - could interact with Severus. Hermione would be curious about Severus as a girl and might try to learn from her knowledge of potions. And Severus, in turn, could be both annoyed and impressed by Hermione's eagerness and intelligence.
Padmé could also be an important character. Their relationship would become very complex. It might turn into a different kind of friendship or even a rivalry. Padmé could offer advice to Anikin on how to handle being a girl in a male - dominated world like the Star Wars universe.
Obviously, the heir of Madara would be a main character. There might also be other characters from the original Naruto series, like Naruto himself. Naruto could be in opposition to the heir, seeing them as a threat to the peace he has worked so hard to achieve.
Obviously, Madara himself is a main character. He is the center of the story's legacy aspect. Naruto might also be a main character as he often represents the new generation and the hope for change in the Naruto universe. He could be the one to either oppose or understand Madara's legacy in the fanfiction.
Naruto himself could still be a main character. His relationship with Madara's reincarnation could be explored, like how he tries to understand this new version of an old enemy and whether he can trust him or not.
Sasuke would probably interact differently. As a girl, Naruto might be more of an enigma to him. He could be more protective or more conflicted in his feelings towards her. Instead of just seeing her as a rival, there could be a romantic undertone in their interactions.
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.
Astrid is likely to be one of the main characters to interact with Hiccup. She might be initially very confused or even a bit jealous depending on how she perceives Hiccup's new form. Stoick, Hiccup's father, would also have significant interactions. He would probably be shocked at first but then try to support his child in this strange situation. And of course, Toothless. Their bond is so strong that Toothless would surely be involved, perhaps trying to understand what has happened to his rider.
