His friends' relationship with baby Sora would change significantly. Riku might feel a stronger sense of responsibility towards him. Kairi, on the other hand, could be more motherly. They would have to communicate differently with Sora since he's in a baby state, and they might have to be more patient when trying to understand his needs or what he's trying to convey.
Well, his friends would probably become more protective. They might see him as a vulnerable little being that needs constant care. Donald and Goofy, for example, would likely be extra vigilant in keeping him safe from any danger in the different worlds they visit.
With Kairi, they could become closer as girlfriends in a sense. They might share more girl - talk, like about their feelings for the boys in their lives. Kairi could also help Sora get used to her new female body, teaching her things like how to style her hair or choose the right clothes. But at the same time, there could be a bit of jealousy if other boys start showing interest in Sora.
One way could be through the power of friendship. If Donald, Goofy and Kairi were to combine their strength and positive emotions towards Sora, it might be enough to draw his heart back. Another possibility is that there could be some kind of magical artifact or power within the fanfiction's world that has the ability to restore lost hearts. Or perhaps Sora himself has some latent power that he can tap into even without his heart, which could help him in the process of regaining it.
As a baby in the fanfiction, Sora has several challenges. He has to rely on others for survival, which is a big change from his independent self. His lack of physical strength means he can't defend himself or explore freely. Moreover, his friends might not always understand what he wants or needs. He may also have trouble adapting to the sudden change in his body and abilities. In the complex and often hostile 'Kingdom Hearts' universe, this could lead to many dangerous situations for him.
It could become more protective. Shiro might feel the need to look out for Sora more, since Sora in a female form might seem more vulnerable. For example, in dangerous game situations, Shiro would be more likely to step in front of Sora.
Well, it depends on how you look at it. Technically, in official Kingdom Hearts content, Sora is a key character. But in the realm of fanfiction, many writers take the essence of Sora and create their own unique stories that are not part of the official canon but are still inspired by the Kingdom Hearts universe. So, in that sense, he can be considered as a major element in Kingdom Hearts fanfiction.
Well, his relationship with Sasuke could be very interesting. Sasuke might see Naruto's fox form as a new level of power to either compete with or respect. Naruto, on the other hand, might be more protective of his friends in his fox form, which could make Sasuke question his own motives. And for his other friends like Shikamaru, he would have to come up with new strategies to work with Naruto in this new form.
His friends would be both amazed and a bit scared at first. Hermione would immediately start researching ways to turn him back. Ron might be more in awe of Harry's new form, but also worried about how dangerous it could be. Their dynamic would shift as they now have to protect Harry in a different way. They might also have to hide his transformation from others who could misunderstand and try to harm Harry.
Well, it depends on how the fanfiction portrays it. In some cases, his friends could turn against him completely. They might see him as a danger to the wizarding world. But in more positive portrayals, they would see this as just another challenge for Harry to overcome. They would be there for him, but it would be different. For instance, they might have to help him find new ways to do magic since the vampire bite could potentially affect his magic in some ways. Their relationship would be a mix of loyalty and a new kind of understanding as they all deal with this unexpected change in Harry.
The plot might involve Sora trying to find a way to turn back into his original form. In the process, he discovers new powers that are unique to his female form. For example, she might have a stronger connection to a certain type of magic. Along the way, she also has to deal with the reactions of the different characters in the Kingdom Hearts universe, some of whom are confused, while others are intrigued by this transformation.
Their relationship can be developed through shared battles. When they fight side by side against strong enemies, they'll learn to trust each other more.
