With his other classmates, they might become closer. For example, if Bakugou gets hurt in a heroic act, his classmates will respect him more and be more eager to be his friend. They'll also be there to support him during his recovery, which could strengthen their bonds.
His relationship with Deku might change significantly. Usually, Deku is seen as someone Bakugou has a complex relationship with. When Bakugou gets hurt, Deku could become more protective or Bakugou might finally start to see Deku in a new light, as someone who truly cares about him.
His relationship with Sasuke might change. If he gets a very powerful gift, Sasuke might see him in a new light, either as a greater rival or as someone he can truly rely on. For example, if Naruto gets the gift of seeing the future, he could prevent Sasuke from making some bad decisions.
His relationship with Sasuke could change significantly. With the new doujutsu, Naruto might be able to understand Sasuke's motives better or even be able to sense when Sasuke is in danger from afar, leading to more protective or empathetic interactions.
Naruto's relationship with his friends in the Hidden Leaf Village would also change. Some might be in awe of his new power, while others might be a bit afraid. For example, Sakura might be worried that the Mangekyou Sharingan could change Naruto's personality. Naruto would have to reassure them that he's still the same person. And he might also use his new power to protect them more effectively, strengthening their bond.
Well, with Dipper becoming a girl in the fanfiction, his relationship with Mabel would have a new dynamic. Mabel would be all about embracing Dipper's new form. She'd be planning slumber parties and trying to give Dipper a new 'girly' identity. As for Wendy, Dipper might find himself more in tune with Wendy's interests on an emotional level now that he's a girl. Wendy might be more open to sharing her feelings with Dipper - girl. His relationship with the townspeople could also change. Some might be more accepting, while others might be a bit more judgmental. And his relationship with the supernatural elements in Gravity Falls could be different too. Maybe some entities are more attracted to his new form, while others are repelled, which would lead to a whole host of new adventures and challenges in their relationships.
Well, if Kara gets hurt, Lena might become more protective of her. She could start to be more involved in Supergirl's battles, not just as a scientist providing tech support but as someone who is truly invested in Kara's safety. This would make their relationship closer and more interdependent.
He might become more responsible. Since One for All is such a significant power, he'd have to step up. He couldn't just be as reckless as he used to be.
His relationship with Midoriya would become more complex. Since Midoriya originally had One for All, there could be some tension as Shoto now has the power. But they could also bond over sharing this special ability, training together to figure out new ways to use it.
His relationship with Sasuke would likely be affected. Sasuke might initially be suspicious of Naruto's new form, thinking it could be a trick by an enemy. But as time goes on, they could find new ways to work together. Naruto's new Kitsune powers could complement Sasuke's skills. For example, Naruto could use his enhanced speed as a Kitsune to keep up with Sasuke in combat.
His relationship with Sakura might change. Sakura would be even more impressed with Naruto having this new power. She might see him as an even greater ninja and could potentially develop stronger feelings for him. Naruto, on the other hand, might use his telekinesis to do small things for Sakura, like picking flowers for her without having to touch them.
As for his relationship with the rest of the village, some might be suspicious at first. The Sharingan has been associated with the Uchiha clan, which has had some dark moments. But as Naruto shows that he can use the power for good, they would gradually accept it. However, there would always be some who are wary, which could create some interesting social dynamics in the village.
