If the fanfiction has a more magical or fantasy element, it could be the magical creatures or spirits that Davis was associated with. Sakura Motomiya, when she replaces him, would start interacting with these beings. For instance, if Davis had a special bond with a certain forest spirit, Sakura would now have to build her own relationship with it. Her different personality might make the spirit react differently, either being more friendly or more cautious towards her.
Well, perhaps in this fanfiction, Sakura Motomiya replaces Davis in a love story. Davis might have had a certain relationship or potential relationship, and when Sakura takes his place, she interacts with the other characters in a completely different way. She could charm the love interest with her own charm, which is different from Davis's, and create a whole new love triangle or just a different kind of romantic story altogether. Also, her backstory and her own set of values might influence how she approaches the relationship, unlike Davis.
Well, it's hard to say who the 'best' is as it depends on personal taste. But some authors who are quite popular in the Sakura Motomiya fanfiction community might be those who really capture her personality well. For example, there's an author named Lily who writes very detailed stories about Sakura's daily life with a touch of magic, making her seem like a real person.
One interesting Sakura Motomiya fanfiction could be about her going on a magical adventure in a new, uncharted realm. She might discover new powers and meet unique characters along the way.
Naruto, of course. Since they are in the same team in the original story, it's very likely that Sakura will interact with Naruto. She might try to change his fate or help him in a different way. Sasuke is also a main character she'll interact with. Maybe she'll try to prevent Sasuke from going down his dark path. And Kakashi, as their teacher, will also be involved in their interactions.
Naruto could also be involved in interactions with evil Sakura. Naruto, being the protagonist, would likely try to understand why she has turned evil and might attempt to bring her back to the good side. Their interactions could be full of tension and emotional moments.
Definitely some of the Akatsuki members. Itachi could be one. He is a complex character with his own motives. His presence could add a lot of mystery to the story as Sakura might try to figure out his true intentions. Another could be Deidara. His explosive personality and love for destruction could create some intense confrontations with Sakura.
Obviously, Sakura would be one of the main characters. And the members of the Akatsuki would also be important. For example, characters like Itachi or Pain might play significant roles as they are key figures in the Akatsuki. They could be mentors or antagonists to Sakura depending on how the story is written.
Obviously, Naruto and Sakura would be the main characters. Naruto is the one who is 'over' Sakura, so his transformation in terms of his feelings towards her would be a central aspect. Sakura, too, would play a crucial role as the object of his former affections and as someone who might react to his new stance.
Well, Karin is for sure a main character as she is taking over Sakura's position. Sakura, although being replaced, still has an important role as the benchmark for Karin's replacement. Then, other characters in their shared universe who interact with either of them could be main characters too. For instance, Naruto could be involved, seeing as he is friends with Sakura and may have some sort of reaction to Karin replacing her. Also, characters from their respective teams or groups might be main characters as they would be affected by this replacement.
Obviously, Tony and Peter are the main characters. Tony, with his genius intellect and wealth, and Peter, the young and spry superhero. There could also be other characters like Pepper Potts who might be involved in the story, perhaps trying to mediate between Tony and Peter or having an opinion on Tony replacing Peter.
