His relationship with Aunt May would be heart - breaking. Aunt May would be in denial and would constantly try to remind Peter of who he really is. She would be the voice of his humanity, trying to pull him back from the brink of becoming a full - on Carnage - like monster.
His relationship with MJ would be severely strained. She would be terrified of this new, violent - looking Peter. She might try to distance herself at first, but then later try to bring back the old Peter.
His relationship with MJ would become very different. Instead of a romantic partner, she might become more of a protective caretaker. She would have to deal with a baby - like Peter, which could be both challenging and endearing.
His relationship with MJ would be completely shattered. Instead of being the loving boyfriend, he could become possessive or even abusive. His friends at school would be terrified of him. Ned, who was once his closest friend, would probably try to avoid him or even try to find a way to stop him. And his relationship with the Avengers would turn into enmity. They would see him as a threat and would try to contain or stop him.
Inuyasha's relationship with his enemies would also change. Some enemies might underestimate him in his baby form, not seeing him as a threat. However, some might see it as an opportunity to get rid of him once and for all. His friends would have to be extra vigilant in protecting him. And as Inuyasha grows up again in the story, his relationships with his friends would be different because of this experience. They would have a shared memory of taking care of him when he was at his most vulnerable, which could deepen their loyalty and friendship.
His relationship with Kagome would change significantly. Kagome might see Inuyasha in a new light, perhaps more as a sister - like figure at first, but then as she gets used to the new form, there could be a shift in their romantic undertones. With Miroku, Miroku would be more respectful in a different way. He might be less likely to tease Inuyasha in the same way he did before. Sesshomaru, on the other hand, might initially be disgusted or confused by his half - brother's new form, but it could also lead to some interesting developments in their rivalry as Sesshomaru tries to figure out if this new Inuyasha is still a worthy opponent.
In a fanfiction where Issei turns into a dragon, his relationships would be in flux. His relationship with his mentors or those he looks up to might change as they now see him as a different kind of being. They might treat him with more caution or more respect depending on how they view dragons. His friendships with his peers would also be altered. Some might see him as a weapon to be used in their battles or struggles, while others would see him as a friend in need of support. Romantically, if he had feelings for someone, that person would have to deal with the fact that Issei is no longer fully human. There could be jealousy from others who might want to be with the powerful dragon - Issei, or there could be newfound admiration from those who previously overlooked him.
His relationship with MJ would likely become more protective. MJ might worry more about Peter and be more involved in his day - to - day life. She could also be his eyes in certain situations, like describing the layout of a new place or a new threat. With Ned, Ned would probably be more hands - on in helping Peter with technology. He might modify Peter's web - shooters to have more audio or tactile feedback.
His Pokémon might be really confused at first. They're used to Ash as a human, so seeing him as a Pikachu would be quite a shock. But some of them, like Pikachu himself, might feel a closer bond since Ash is now in a similar form.
His relationship with his parents would likely change. His mom might start treating him more like a daughter, perhaps with different rules or expectations. His dad might be a bit more protective. With his friends, the boys might be a bit more shy or awkward around him at first. And the girls might be more accepting and include him in their girl - only activities.
His relationship with himself would also change drastically. He would have to grapple with his new identity as a dark side user. There would be inner turmoil as he might still have some remnants of his former self. He could struggle with the moral implications of his actions and the new powers he has. This internal conflict could also affect how he interacts with others, making him more unpredictable and volatile in his relationships.
His relationship with his uncle Iroh would be deeply affected. Iroh has always been a guiding figure for Zuko. If Zuko turns into a dragon, Iroh would be worried but also proud in a way. He would search for ways to help Zuko, and their relationship would become more about Iroh protecting and guiding Zuko in this new and strange form. Zuko, in turn, would rely more on his uncle's wisdom during this time.
