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.
If Peter turned evil, his relationship with his community would be ruined. The people who once saw him as a hero would now fear him. His interactions with the police would change from a somewhat friendly cooperation to a hostile stand - off. As for his enemies, they might initially be happy to see him on their side, but they would soon realize that an evil Peter Parker is a very unpredictable and dangerous ally. He could turn on them just as easily as he turned on his former friends. And his relationship with his teachers at school would be non - existent as he would likely abandon his normal life and any pretense of being a regular student.
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 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 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 relationship with Aunt May could become strained. Since becoming a Savitar fan, Peter might be more reckless in his pursuit of power. Aunt May, who is used to the more cautious Peter, would be worried. His friends like Ned and MJ would also be concerned. Ned might try to talk him out of it, fearing that Peter is getting in over his head. MJ, on the other hand, might be intrigued but also worried about the changes in Peter.
His relationship with Aunt May would be more complicated. She'd be even more worried about him. With super soldier abilities added to his spider - powers, he might be getting into more dangerous situations. She could start to suspect something is different about him when he shows even greater strength or endurance around the house.
His relationship with Mary Jane would likely change a great deal. She might be in awe of him, but also a bit intimidated. Peter, now a god, would have to struggle to maintain the same level of intimacy they once had. With his friends like Ned, they might see him more as a protector. Ned would probably be excited about Peter's new powers at first, but then realize that their friendship has become more complex. And his enemies? They would either be terrified of him or try to find a way to bring him down.
In his relationship with MJ, it could add a new layer of complexity. MJ might be more empathetic towards Peter's situation. There could be some really sweet moments where she learns sign language just to communicate with him better, and they develop a stronger emotional connection through this shared effort of understanding each other in a different way.
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.
