He might be shocked at first. In many fanfictions, Adrien would feel a mix of disbelief, anger, and sadness. He has always known his father as a strict but loving parent, and finding out he's Hawk Moth, a supervillain, would completely shatter his view of him.
Some of his other friends might react differently too. Some may be more cautious around him, worried about the power of the jinchuuriki within him. But those who truly trust Naruto, like Shikamaru, might not change their attitude much. They would see that Naruto is still the same person he was before, just with this added aspect to his identity.
I like 'The Day Naruto Found Minato'. In this fanfic, it starts with Naruto accidentally stumbling upon a time - travel jutsu that takes him to meet Minato in the past. It's really interesting to see how Naruto interacts with his father in that different time period. There's also 'Naruto and Minato: A New Bond' which explores the psychological aspects of their relationship, like how Naruto overcomes his initial disbelief and then starts to build a strong bond with Minato.
Naruto might initially be confused. He has grown up with a certain view of himself, and this new information about his heritage completely shatters that. He may struggle with his identity for a while, but as he digests the information, he could start to feel a sense of pride. He might think that now he has a greater purpose, something that ties him more closely to his family and the ninja world in general. He may also become more confident in his abilities, knowing that he comes from a great lineage.
Well, in this fanfiction scenario, if Naruto discovers Tsunade is his mother, it could change his entire world view. He has always seen Tsunade as a strong and somewhat intimidating figure in the village. Now, as his mother, she could become a more nurturing presence. Naruto might also start to question his own identity more deeply. He's used to being the orphaned Naruto, but now he has a family connection to one of the most powerful people in the village. This could lead to new storylines about him learning more about his family history and what it means to be related to Tsunade.
His confidence would probably soar. Knowing he has his parents, who are likely strong ninjas, supporting him would make him feel more secure. He might become a bit less reckless as he now has people who care about him deeply and he wouldn't want to worry them.
Well, in these fanfics, the discovery of Minato by Naruto can have far - reaching consequences for the plot. It could lead to a faster resolution of some of the long - standing issues in the Naruto universe, like the feud between Konoha and other villages. Minato might be able to use his influence and knowledge to broker peace. Also, on a more personal level, Naruto's relationships with his friends and mentors could be altered. For instance, he might rely more on Minato's advice than on Kakashi's in certain situations, which would change the dynamics of their interactions.
It could start with Naruto shouting at Minato, expressing all his pent - up emotions. Minato would be taken aback at first, but then try to calmly explain his side. Naruto, however, might not be in the mood to listen and keep on ranting. Eventually, Minato might use his calm and wisdom to get Naruto to at least hear him out.
Naruto would probably want to introduce his parents to all his friends. It would be a big moment for him to show off his family, especially to Sasuke. His relationship with Sasuke could also be affected in a positive way as Naruto now has a more complete family.
Well, one thing that could happen is that Naruto would be overjoyed. He has always longed for a family, and to suddenly find out his parents are alive would be a dream come true. He'd probably have a million questions for them about his past, why they had to be away, and what their lives were like. And his relationship with his friends might change a bit too, as he now has this new family aspect to his life.
