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.
Ezra would become more ruthless. His once kind and empathetic nature would be replaced with a cold, calculating demeanor. For example, he might not hesitate to sacrifice innocent lives if it served his purpose. His relationships would also change drastically. His friends would become either obstacles to be removed or pawns to be used.
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 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 Alfred would be severely strained. Alfred has always been Batman's moral compass and a source of support. If Batman joined the Dark Side, Alfred would be heartbroken and would try his best to bring Batman back to the light. There would likely be many arguments between them as Alfred tries to remind Batman of his true values.
His personality would become more aggressive. The once kind - hearted Ezra would be replaced by a more self - centered and power - hungry individual.
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 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 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.
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.
