The relationship in a child Shirou x Saber fanfiction would be much more about discovery and growth on Shirou's part. Since he's a child, he has a lot to learn about the world, and Saber can be a part of that learning process. Unlike in the original where Shirou has his own set of ideals already formed, as a child, Saber's presence can shape his ideals from the very beginning. Their bond would be based on Shirou's wide - eyed wonder and Saber's sense of duty to protect and guide him.
In the original, they're just friends and partners. In the fanfiction, with Judy being a vampire, there would be a new level of secrecy. Nick might be more protective of Judy, and their relationship could become more intense. There could be a lot more trust - building as Judy reveals her true self to Nick.
In fanfiction, their relationship could develop in a more friendly way. Instead of just being acquaintances in the original story, they could become true friends. They might start training together, sharing their knowledge of martial arts and life experiences.
In the high school fanfiction, their relationship could develop in a more light - hearted way. For example, they could be in the same art class. Naruto might draw some silly pictures that make Gaara crack a small smile. This is different from the original where their interactions were often more intense and centered around battles and the fate of their villages. Here, they could develop a friendship through shared hobbies and school events, like a school play where Naruto convinces Gaara to join in.
In fanfiction, their relationship could take a more romantic turn compared to the original. Maybe Gray Wing becomes more protective of Turtle Tail, and Turtle Tail starts to see Gray Wing as not just a friend but a potential mate. They could have moments where they exchange gifts, like Gray Wing bringing Turtle Tail a special flower, which is a sign of his growing affection. This is different from the original where their relationship was more platonic.
Well, in fanfiction, their relationship could develop more quickly. For example, during the Chunin Exams, Naruto might actually confess his feelings for Sakura in a moment of high stress. This would be different from the original where he was more shy about it.
In the original story, Sasuke was often cold towards Naruto. With Fem Sasuke in this fanfiction, Naruto's intelligence could break through her tough exterior more quickly. He might use his smarts to show her different perspectives, which could lead to a faster development of trust between them. For instance, Naruto could analyze her past traumas in a way that makes Fem Sasuke feel understood, and this would change the dynamic of their relationship significantly.
The original series has a certain pacing and development for their relationship. But in the fanfiction, the Arrancar aspect of Ichigo could speed things up. For example, Arrancar Ichigo might have a more primal, possessive side towards Rukia. This could lead to a more passionate and tumultuous relationship. Also, they would face different external threats and challenges because of Ichigo's new form, which would force them to rely on each other in new ways and thus change how their relationship develops.
In the original story, Luffy has a sort of idol - worship relationship with Shanks. But in a fanfiction with Female Luffy, there could be a more emotional and complex relationship. Maybe Female Luffy has a crush on Shanks when she's younger, which adds a different layer to their interactions. She might be more eager to prove herself to him not just as a great pirate but also as someone worthy of his attention.
In the fanfiction, their relationship might start with a sense of rivalry. Fem Naruto, being a strong - willed character, might initially see Haku as a competitor. However, as they get to know each other better, they realize they have more in common than they thought. This realization could lead to a more complex relationship. Haku could be more protective of fem Naruto, and fem Naruto could be more open - minded towards Haku's way of life, which is a big departure from the somewhat one - dimensional relationship they had in the original story.
Well, as Genin, they could start off as more competitive. Maybe in a sparring session, Hinata surprises Naruto with her new jutsu, and this makes Naruto more interested in her abilities rather than just her feelings for him. This could lead to a relationship based on mutual respect for skills first.
