In fanfiction where Goku keeps his memory, how does it affect his relationships with other characters?

For Goku's relationship with the other Z - Fighters, it could be a mixed bag. Some, like Piccolo, might see the tail as a potential weakness that enemies could target. So he might be constantly on Goku to protect it. On the other hand, Yamcha might be jealous that Goku has this unique feature that makes him stand out even more. However, overall, Goku's tail could also be a unifying factor. It could remind them all of Goku's alien origin and make them more aware of the vastness of the universe and the different species within it, which could strengthen their bond as a group.

In such a fanfiction, Naruto keeping to himself might make others initially find it hard to approach him. For example, his friends like Sasuke and Sakura might be a bit confused at first. Sasuke, who is also a bit of a loner in his own way, might not know how to deal with this new Naruto. Sakura, on the other hand, might try harder to break through his shell. This could lead to some strained relationships at the start, but as the story progresses, those who truly care about Naruto would try to understand him better and build deeper, more meaningful relationships with him.

It changes his relationships in many ways. Percy's memories would give him an edge in understanding the overall demigod world better than the Romans around him. This could lead to some admiration from the younger or less experienced demigods, but also some envy from the more prideful ones. In terms of his relationship with the gods, he might be more skeptical or demanding since he remembers all the times they've let him down in the past. And when it comes to potential love interests among the Romans, his heart would still be with Annabeth, which could cause some romantic tension and confusion.

In certain fanfictions, the izuku system is a secret. This secrecy can strain his relationships as he has to constantly lie or be evasive about his sudden improvements. But when the truth comes out, it can either lead to a huge rift or a deeper understanding among his friends, depending on how the writer chooses to portray it.

His relationship with his sensei, like Kakashi, could become more complex. Kakashi would feel guilty for not being able to protect Naruto from the experiments. And Naruto might start to question Kakashi's ability to keep him safe. This could lead to a strain in their relationship at first, but later they could grow closer as Kakashi helps Naruto recover from the trauma of the experiments.

His relationship with Ron and Hermione could be severely strained. They might be caught between their loyalty to Gryffindor and their friendship with Harry. Ron, who is very proud of being a Gryffindor, might struggle to understand Harry's situation and this could lead to arguments between them.

With his friends in Konoha, they would be worried and perhaps a bit afraid. They know Orochimaru's reputation as a villain. Naruto's friends like Shikamaru might start to keep a closer eye on him, which Naruto could resent. He would feel like they don't trust him anymore, and this could strain their friendships.

Well, it might make his relationships more intense. His Saiyan nature often means he's more aggressive and competitive. So, his friends like Krillin might be a bit more cautious around him. And his enemies would feel even more threatened. It could also lead to some friction with Vegeta as they both have Saiyan pride and might butt heads more often.

With the teachers, like Dumbledore, he might be treated differently. Dumbledore might see this transformation as an opportunity for Harry to learn new things about the wizarding world from a different perspective. And some of the more traditional teachers might have different expectations of Harry's behavior in class now that he is a girl.

If Naruto has a physical disability like a broken arm that doesn't heal properly in fanfiction, his friends like Sasuke and Sakura would need to step in and help him more. Sasuke might be more protective, which could change their dynamic from a competitive one to a more collaborative one. Sakura could use her medical skills to try and find a way to heal him, which would bring them closer. His relationship with his teachers, like Kakashi, would also change as they'd have to adjust their training methods.
