Perhaps an ancient evil that was sealed away long ago is awakened when Minato is revived. This entity could be a powerful demon or a dark ninja from the past.

Minato, with his skills and knowledge, has to figure out how to defeat this ancient evil with the help of Naruto and the other Leaf Village ninjas.
Perhaps a new and original antagonist could be created for this fanfiction. This antagonist could be a rogue ninja who has mastered a forbidden jutsu that allows him to manipulate time as well. He could be the one who sets up the events that lead to Minato's endangerment, and Naruto has to figure out his motives and stop him while also saving Minato.
Maybe an old enemy who was thought to be defeated but has somehow returned stronger. Orochimaru could be a possibility. He was always obsessed with power and immortality. If Naruto is revived, Orochimaru might see it as an opportunity to study Naruto's new state of being (since he was revived) and use that knowledge for his own dark purposes.
A 'Naruto Minato Revived' fanfiction could have a plot where Minato is revived in a time of relative peace. He has to adjust to the new world where his son is a hero.

He might also be involved in some political intrigue within the village as some might fear his power or see him as a threat to the new order.
Yes, there are several fanfictions where Minato is revived. In many of these stories, it often changes the course of the Naruto universe significantly.

Minato's revival could also have a big impact on the political situation in the ninja world. He was a respected figure and his return might lead to a re - evaluation of alliances and treaties.

One possible plot could be that Naruto discovers a powerful jutsu that can bring back the dead. He decides to use it on Minato to seek his father's guidance in a difficult situation, like dealing with a new and powerful enemy threatening the Hidden Leaf. Then, Minato could use his skills and knowledge, which are different from the current generation, to help Naruto and the village in new ways.
The Akatsuki would still likely be the main antagonists. They have their own goals that often conflict with the well - being of the ninja world. Even with Minato alive, they are a powerful and organized group that would pose a great threat.
