Sasuke might initially be indifferent on the surface, but deep down he would feel a sense of loss. He has always had a rivalry with Naruto, and Naruto's departure would mean an end to that dynamic. Sakura would be devastated. She has grown to care about Naruto as a friend and teammate, and his leaving would leave a big hole in the team.
For Kakashi, he would be disappointed. He has been training Naruto and seeing his potential. Naruto leaving would mean losing a student he has high hopes for. Sasuke might start to question his own actions and place in the team without Naruto there as a sort of counterbalance. Sakura, on the other hand, might try to convince Naruto to come back, going to great lengths to find him and persuade him.
Sasuke could also see Naruto's leaving as a sign of weakness at first. But as time goes on, he might realize how much Naruto actually contributed to the team's balance. Sakura would likely be angry as well as sad. Angry at Naruto for leaving without proper explanation and sad because she misses him. Kakashi would try to keep the remaining team members together and might also try to find out the real reason behind Naruto's departure.
Sasuke would likely be devastated. Despite their past differences, Naruto was his rival and in a way, his closest friend. He might go into a deep state of regret and isolation. Sakura would be heart - broken. She loved Naruto, and his death would be a huge blow to her. She might become more withdrawn and focus all her energy on her medical ninjutsu. Kakashi would be filled with a sense of failure. He was Naruto's teacher, and he would feel responsible for not being able to protect him.
Sakura's reactions can vary. Sometimes she tries to get revenge on Naruto for his pranks. If he plays a prank that makes her look silly in front of Sasuke, like the fake love letter prank, she'll be really mad and try to think of a way to make Naruto pay. Sasuke might pretend not to care, but if the prank affects his image too much, like the hair product switch, he'll give Naruto a cold stare. Kakashi is more laid - back and just watches the whole thing unfold like it's entertainment.
Sakura would be heartbroken. She'd likely spend hours upon hours by Naruto's side, trying to jog his memory with stories of their adventures together. She might even get a bit overbearing in her attempts. Sasuke, who has his own complex relationship with Naruto, would be conflicted. He'd see Naruto's forgetfulness as a sign of weakness at first but then realize the importance of their bond. Kakashi, being the experienced leader, would start by observing Naruto carefully to see exactly how much he has forgotten and then start a systematic process of helping him remember.
Well, Sasuke might initially be a bit shocked but then he'd try to hide his concern. Sakura would be very empathetic and might immediately want to do something to help Naruto. Kakashi, being the experienced one, would take a more calm and strategic approach to deal with Naruto's situation and protect him from further abuse.
After the initial shock, Naruto could become determined to prove his innocence if that was the case. He's a fighter, and he wouldn't just let this false accusation or betrayal stand. He might set out on a journey to find the truth and clear his name, all while struggling with the pain of his friends' actions.
Well, Turles' relationship with Goku could start off on a bad foot. Goku is all about protecting the Earth and its people, while Turles has been more about self - gain. But as they fight side by side, Turles might see Goku's way of life as something to aspire to. With Vegeta, it would be like two bulls in a china shop. They'd constantly be trying to outdo each other in terms of power and Saiyan pride. However, with the Earthlings on the team, Turles would have to learn to work with them. He might be surprised at how resourceful Krillin can be in a fight or how Bulma's inventions can be useful in their battles. And over time, these relationships could evolve into something more positive and collaborative.
Naruto and Shikamaru would have an interesting relationship. Shikamaru might find Naruto's impulsiveness annoying at first but would later learn to appreciate his determination. Naruto, on the other hand, would respect Shikamaru's intelligence and might try to learn some strategic thinking from him. With Choji, Naruto would bond over food very quickly. They could have eating contests and in the process, become really good friends. As for Ino, Naruto would probably have a bit of a rocky start. Ino might see Naruto as a bit of a nuisance, but as they go on missions together, she would see his good heart and they would become friends too.
It could be some of the younger ninjas from the village who look up to Naruto. Maybe a young genin who has a special ability with earth jutsu, and another who is really good at stealth but lacks confidence. Naruto would then help them grow.
They would be shocked at first. Minato would be filled with pride and joy seeing his son all grown up. Kakashi would respect Naruto's strength. Obito might be a bit envious of Naruto's popularity but also admire his spirit. Rin would be very friendly towards Naruto.
When Team Minato meets Hokage Naruto in a fanfiction, their reactions would depend on their individual personalities. Minato would be overjoyed and would immediately start asking Naruto about his achievements and how he has led the village. Kakashi would be his usual calm self but would show his admiration through his words and actions. Obito, who has had a difficult journey, might initially be hesitant but then would be inspired by Naruto. Rin would be the most excited, perhaps jumping up and down and saying how wonderful it is that Naruto is the Hokage. This encounter could also lead to a deeper understanding between them all and a strengthening of the bonds between generations.
