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.
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.
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.
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.
One possible plot could be a training session. Team 7, consisting of Naruto, Sasuke, Sakura and Kakashi, might meet Team Minato, which includes Minato, Obito, Rin and Kakashi in his younger days. They could engage in friendly sparring matches. Naruto would be excited to meet his father Minato and learn some new jutsu from him. The two teams could also exchange stories about their adventures, like Team 7 talking about their battles against the Akatsuki, and Team Minato sharing their experiences during the Third Great Ninja War.
In this fanfiction, there could be an epic battle of skills. Team Minato, with their unique abilities from their time, could test the mettle of Team 7. Maybe Minato's lightning - fast speed would be pitted against Naruto's new - found powers. It would be a clash of different generations of shinobi.
Well, if Team Minato meets Team Kakashi in a fanfiction, it could lead to some epic battles or friendly competitions. Maybe they would have a sparring match to see which team is stronger. Team Minato with their speed and unique jutsus, and Team Kakashi with their diverse skills. Or they could collaborate on a mission, with Minato's leadership guiding both teams. It would be exciting to see how the different personalities interact, like Obito from Team Minato and Kakashi from Team Kakashi. They have a complex history that could be explored further in such a meeting.
Minato would be in awe of the new ninja world. He'd notice the changes in the village's infrastructure and the way ninjas are trained. He might be a bit taken aback by the more complex political situations. However, being the quick - thinking ninja he is, he would start to analyze everything. He'd work with Naruto to understand the new power dynamics and use his old - school wisdom along with Naruto's modern knowledge to make the village even stronger.
