One possible scenario in such a fanfiction could be that Kushina's revival has a profound impact on Naruto. She could help him understand more about his Uzumaki heritage and perhaps teach him some long - lost Uzumaki jutsus. Her presence might also change the political situation in the Hidden Leaf, as she was an important figure before her death.
Maybe the plot is centered around Kushina's relationships. She gets to meet her son Naruto as an adult and is proud of the man he has become. She also reconnects with old friends and allies. But then, there are those who are not happy about her return, fearing that she might disrupt the current power balance in the village, and Naruto has to defend her.
On a personal level, for Naruto, it would mean having his parents around. He could finally experience a real family life. Kushina could teach him more about the Uzumaki clan's techniques and traditions. Minato could train Naruto further in his unique jutsu. Emotionally, it would be a great comfort for Naruto and many of his friends who knew about his longing for his parents.
In some fanfictions, Naruto might use some super powerful jutsu he created or mastered. Maybe it's a new form of Sage Mode that can reverse time on a small scale. Another possibility is that he found some ancient forbidden technique hidden in the Uzumaki clan's secrets.
If they are revived, Naruto's relationship with his parents would be much more complex. He has grown up without them, and now he has to adjust to having them around. Minato and Kushina would also have to get used to the fact that Naruto is no longer the little boy they left behind. Their relationship would be filled with a mix of catching up and learning about each other all over again.
There could be a plot twist where they are revived in a different time period. Maybe they are brought back during the era of the Sage of Six Paths. This would mean they have to adapt to a very different world with different rules and powers. Another plot twist could be that when they are revived, they are linked to an ancient evil. They have to fight this internal connection while also trying to figure out what has happened to the ninja world in their absence. Additionally, it could be that their revival was actually a test by the gods of the ninja world to see if they can bring about a new era of peace.
I haven't actually read this fanfiction yet. But if Naruto is revived in it, there could be so many interesting plot twists. Maybe he comes back with new powers or a different perspective on the ninja world. It might also explore how his return affects his relationships with his friends and the village.
Another aspect could be that the fanfiction delves into how Kushina's presence affects Naruto's relationships with others. For instance, his relationship with Sasuke could be different. With a strong maternal figure in his life, Naruto might be more stable emotionally and be able to approach Sasuke in a more understanding way, which could potentially change the whole dynamic of their rivalry and friendship.
Yes, there are several fanfictions where Minato is revived. In many of these stories, it often changes the course of the Naruto universe significantly. His revival can lead to different interactions with Naruto, and he might use his skills and knowledge to help Naruto in new ways, such as teaching him more about the Uzumaki clan secrets or providing unique combat strategies against new enemies.
One can expect a lot of emotional moments. His friends would be overjoyed to see Naruto back. And Naruto himself would probably be a bit disoriented at first, having to come to terms with being alive again. It could also involve some sort of quest that only Naruto can undertake now that he's revived.
