In such a fanfiction, Shirou - turned - Avenger could be on a path of vengeance against those he believes have wronged him or his loved ones in the past. This could lead to a series of intense battles where he uses his new - found powers in a more brutal way compared to when he was just Shirou. And his relationships with other characters would also change drastically, like with Rin or Saber, who might be initially shocked and then try to bring him back to his former self.
A possible plot development could be that Naruto's connection to the Nine - Tailed Fox gives him an advantage in a situation where Shirou was at a disadvantage. For example, if there was a powerful dark force in the story, Naruto could use the Nine - Tailed Fox's power to fight it off, while Shirou might have struggled more. Also, Naruto's charisma could attract different allies compared to Shirou, and these new allies could bring in their own sub - plots and story arcs.
Another aspect could be the way Shirou's relationships change. His friends, like Rin or Sakura, would be shocked and confused by his transformation. They might try to bring him back to his old self, which could lead to a lot of emotional and tense moments. The fanfiction could explore how far they are willing to go to save Shirou from his new Avenger self.
Well, it could start with Jasper's reasons for turning Bella. Maybe he sees a potential in her that no one else does. After the transformation, Bella might go through a phase of self - discovery. She could be exploring the new world of vampires, learning about their history and culture. And there would be the inevitable love triangle or quadrangle situation. With her new vampire allure, she might attract other vampires, causing some jealousy or competition among them, especially if Edward is still in the picture.
Perhaps Shirou becomes an Avenger due to a misinterpretation of his ideals. He always wanted to be a hero who saved everyone, but in a world where his actions are constantly misconstrued and lead to more harm than good. He could be driven to the point where he believes that only by taking revenge on those who wronged him and his loved ones can he set things right. This would be a very complex and angsty storyline.
Shirou might develop better teamwork skills. In multiplayer games, he'll need to cooperate with others. This could be a big change for him as he's often used to working alone. He'll learn to trust his teammates and communicate effectively, which will in turn make him a more well - rounded person in both the gaming and real - world scenarios.
Shirou as Avenger would probably lose some of his idealism. He was always about saving everyone, but as Avenger, he might focus more on retribution. His relationships would also be affected. He might push away those who care about him because he feels they can't understand his new state. For example, he could become more aloof towards Rin, who was once an important person to him. And he'd be more secretive, hiding his new - found dark side from others.
Albedo might become more empathetic. As a girl, he could experience different social interactions and emotions. He might also become more aware of his appearance and how others perceive him. For example, he could start to care more about his clothing and grooming.
A plot possibility could be that Shirou has to keep his transformation a secret at first. He's afraid of how others will react, especially those he cares about. So he tries to act as normal as possible while dealing with the physical and emotional changes privately. Another could be that some sort of magic gone wrong caused the transformation, and he has to find a way to reverse it while also using his new form to his advantage in battles or other situations.
A plotline could involve Zelretch having a specific reason for turning Shirou female. It could be part of a grand plan to save the world or to correct some imbalance in the magical realm. And as Shirou is now female, she may discover new magical abilities or limitations that come with her new form. This could lead to a whole new adventure as she tries to master these changes while dealing with the overarching plot.
Well, a likely plot development would be that Sasuke's new female form causes a stir in the village. Some people might be suspicious or even hostile towards her change. Naruto would then be in a position to defend Sasuke and prove that she is still the same person deep down. Also, Sasuke might start to explore different aspects of her personality that were suppressed when she was male. This could lead to her having different goals and ambitions, which would then drive the story forward as Naruto tries to support her new - found self. There could also be a plotline where an enemy takes advantage of Sasuke's transformation, and Naruto and Sasuke have to work together to defeat them.
