Like, he could inform them about certain enemies they should be more cautious of, or secrets about the ninja world that they are yet to discover.
Well, one possibility is that they see Kakashi achieving great things in the future. Maybe he becomes an even more respected ninja, leading important missions and training a new generation of powerful shinobi. They might be proud to see how he overcomes his past traumas and grows into a more confident and capable leader.
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.
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.
The 'team minato reads the future fanfiction' could potentially be about Team Minato being thrust into situations where they have to rely on their new - found ability to read the future. This might lead to them making different decisions in battles or in their daily lives. They could be faced with moral dilemmas too. For instance, if they see a future where they win a battle but at a great cost to innocent lives, they would have to decide whether to change that future or not. It could also explore how this ability affects their growth as ninjas and as individuals.
In a fanfiction where Team Minato meets future Obito, it could be a very emotional encounter. Minato might be shocked to see how Obito has changed. Obito, having experienced so much in the future, could bring warnings about future disasters. For example, he might warn about the upcoming threats to Konoha. Team Minato would have to grapple with the knowledge that Obito is no longer the person they once knew.
At first, Kakashi might try to distance himself from Team 7's possessiveness. He values his independence and doesn't want to feel smothered. However, as he realizes that their actions are coming from a place of deep love and loyalty, he starts to accept it more. He may even start to rely on them a little bit, for example, allowing them to help him with his paperwork or other small tasks that he usually does alone. This shows a new level of trust and closeness between them.
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.
Minato would react with concern and a sense of responsibility. He'd try to figure out the root of the problem. Kakashi would be reserved but still show empathy. Obito would be more upfront and vocal about his desire to help. Rin would be very gentle and motherly. For example, Minato might ask the reader about her family or dreams that have been shattered. Kakashi could share his thoughts on how he coped when he felt lost. Obito might offer to take the reader on adventures to show her the good in the world, and Rin would make sure she has something to eat and a place to rest.
Obviously, Kakashi is one of the main characters since it's about his time travel. Minato is also a central figure as he is part of Team Minato that Kakashi travels back to be with. And of course, the other members of Team Minato like Obito and Rin are likely to be important characters as well.
