One possible plot could be that Naruto is resurrected by a powerful and mysterious jutsu. He then has to deal with a new threat that emerged while he was gone. He reunites with his old friends and they train together to face this new enemy.
Perhaps Kaguya Otsutsuki is resurrected again, but this time with a stronger will and more dangerous plans. Since Naruto was the one who played a major role in defeating her before, she targets him first in this fanfiction.
If Naruto is resurrected by Edo Tensei in the fanfiction, he could have a different perspective on life and death. Since he's come back from the dead, he might be more determined to achieve certain goals that he didn't fully accomplish when he was alive. He could also interact with characters who have passed away in a very different way. For instance, he could meet his father again and have some deep conversations about the future of the ninja world. This would add a lot of emotional depth to the story.
There's also a possibility that it could be an unknown villain. A new character created by the fanfiction author who has a vendetta against Konoha or the ninja world in general and believes that resurrecting Naruto through Edo Tensei would be a way to start some sort of revolution or destruction.
Maybe Naruto is resurrected by an unexpected force, like an ancient and forgotten jutsu that was thought to be lost. This could lead to a whole new arc where he has to figure out who resurrected him and why, while also dealing with the fact that the world has changed since his death.
It would be a very emotional change. Naruto has always longed for his parents, so their resurrection would be like a dream come true. However, Minato and Kushina would have to catch up on all the years they missed. They would see Naruto as not only their son but also as a hero in the ninja world. Their relationship would be about rebuilding family bonds and learning to trust and rely on each other again. There could also be some cultural differences as Naruto has been influenced by the current ninja society, while his parents come from an older time.
Naruto's relationship with the new generation of ninjas would be interesting. They've only heard stories about him. His resurrection would make him a sort of legend come to life. Some might idolize him immediately, while others might be skeptical. He would have to earn their trust and respect all over again, and in the process, he could form new and unique relationships with these young ninjas.
Well, a plot twist might be that Naruto's resurrection is part of a grander scheme by an old enemy. This enemy brought him back not out of kindness but to use him as a weapon. Naruto, being Naruto, would then have to fight against this control while also dealing with the changes in the ninja world since his death.
His friends would be overjoyed at first. But then they might start to feel a bit of unease. They've moved on in some ways since his death, and Naruto's resurrection could disrupt that. For example, Sasuke might have to re - evaluate his feelings towards Naruto and their rivalry.
One possible plot twist could be that Naruto's parents, Minato and Kushina, are resurrected but they have lost their memories. This would create a whole new dynamic as Naruto has to help them regain their past while also dealing with his own emotions of having them back. Another twist could be that their resurrection is part of a larger, darker scheme by an old enemy who wants to use them against Naruto. For example, the enemy might be able to control them to some extent and make them fight Naruto, which would be a heart - wrenching situation for Naruto as he has to face his beloved parents in combat.
