Well, he would change a great deal. In his normal form, Star Lord is confident and somewhat cocky. But as a raccoon, he could become more timid. He'd have to rely on his new physical abilities, such as climbing and squeezing into small spaces. This might make him more resourceful in a different way. Also, his communication would change. Instead of using words, he might have to rely on body language and simple vocalizations, which could lead to some misunderstandings with his friends at first.
His character would experience a shift in his perspective. As a raccoon, he'd be at the mercy of larger creatures and the environment in a new way. He might develop a new sense of empathy for smaller and more vulnerable beings. His sense of humor could also change. Instead of making sarcastic remarks, he might find humor in things like chasing his own tail or stealing shiny objects. And when he eventually turns back into his human form, these experiences as a raccoon could make him a more well - rounded and humble character.
One possible plot could be that Star Lord, while on a mission, encounters some strange alien technology or magic that accidentally turns him into a raccoon. His team would then have to figure out how to reverse the transformation. They might go on a journey to find a rare artifact or a wise alien being who has the knowledge to change him back. Along the way, there could be a lot of comical situations as Star Lord tries to adapt to his new raccoon form, like trying to use his tools and weapons with paws instead of hands.
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 personality might not change completely. He'd still be the intelligent and laid - back person he was. But he might become more empathetic. Since he's now in a female body, he could better understand the struggles that girls face, which could make him more sensitive to others' feelings.
Dipper's personality change could be quite complex. Since he's now a girl, he might feel more pressured to conform to certain standards. This could make him initially more reserved. But as he gets used to it, his adventurous spirit could shine through in new ways. He might start to approach mysteries from a different perspective, one that combines his old way of thinking with the new insights he has from being a girl. He could also become more protective of those he loves, as he now has a different understanding of vulnerability.
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.
For Naruto, he might become more protective of Sasuke as a girl. Their friendship could take on a different dynamic, with Naruto being more chivalrous perhaps. Sakura might initially be jealous but then they could form a stronger bond as girls sharing common experiences. Kakashi would probably have to adjust his mentoring style to account for Sasuke's new situation.
I think Zoro's core personality of being tough and fearless would remain. However, being in a female body might make him a bit more aware of certain things, like how he's treated differently by some people. But overall, he'd still be the same Zoro who doesn't back down from a fight and is always looking to improve his skills.
Well, it would become a more equal relationship at first. Since Hiccup is now a dragon, he can understand Toothless on a whole new level. They might compete in dragon activities like flying races or hunting together. However, Toothless might also be a bit confused at first, not sure how to act around his once - human friend who is now a dragon.
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.
