They would be empathetic. Minato, as Naruto's father, would especially feel a deep sense of pain seeing his son struggle. He would want to reach out and comfort Naruto during his lonely times when the village shunned him because of the Nine - Tails.
Kakashi, being Naruto's teacher, would be proud of how Naruto overcame his struggles. He would see Naruto's tenacity in the face of difficulties, like when Naruto was trying to master new jutsus or when he was facing strong opponents. Kakashi would think that Naruto was truly living up to the spirit of a shinobi.
Obito might be inspired by Naruto. Obito had his own share of struggles and seeing Naruto fight through his, especially when Naruto was trying to bring Sasuke back to the right path, would make Obito reflect on his own journey. He might see in Naruto a chance for redemption that he once thought was lost.
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.
Well, in fanfiction, if Team Minato watches Obito's future, they might be shocked. For example, they would witness his alliance with Madara and all the destruction he causes. It would be a moment of self - reflection for them. Minato might blame himself for not being there for Obito when he needed it most. Kakashi would also have a hard time seeing his old friend turned into an enemy.
Minato would probably be very proud. He always saw potential in Kakashi, and seeing his future accomplishments in the fanfiction would confirm his belief in him. He might have a big smile on his face and feel a sense of accomplishment as if he had a part in shaping Kakashi into who he becomes in the future.
Minato would likely be extremely shocked. Naruto is his son, and the idea of Naruto attacking him would be completely unexpected. He would probably try to talk to Naruto first, to find out what is wrong and why he is being attacked.
There are many out there. A really good one might focus on the emotional reactions of Team Minato. For example, Minato might be proud of Naruto's strength and how he overcomes Pain. Kakashi could be in awe at Naruto's new techniques. Their reactions can enhance the overall viewing experience in the fanfiction.
Minato might gain new perspectives on the potential of his students. For example, he could see in fanfictions how Naruto or Sasuke could have developed in different ways. Kakashi might start to question some of his own beliefs about the ninja world if he reads some thought - provoking fanfictions. Obito and Rin could see different versions of their own fates and it might make them think about their roles in the original Naruto story.
Well, Naruto would be like a catalyst for change in the team dynamics. He'd bring his unique sense of humor and determination. This would rub off on the others. He could help Obito see the value in the team more clearly. With Kakashi, he could show him that it's okay to rely on others. And for Minato, Naruto could be a source of pride and motivation. His presence would create a more family - like atmosphere within the team, which would make them fight even harder for each other.
One possible story could be that Team Minato time travels to the future. They would be amazed by the technological advancements. Naruto might be excited to see how the village has grown. They could also learn new jutsu from the future ninjas and take that knowledge back to their own time to strengthen Konoha.
If Naruto joins Team Minato in fanfiction, his character growth would be significant. He'd learn about his father's values and ninja way. This would give him a deeper understanding of his heritage. Interacting with Obito and Rin would also teach him about friendship and sacrifice. Naruto would likely become more mature, as he'd be in a team with different personalities. He might also develop new aspects of his personality, like a more serious side when it comes to ninja missions.
