Well, Naruto himself could have a whole new perspective on life after being resurrected. He might be more cautious or more determined than before. For example, if he died protecting the village, he could be even more dedicated to its safety when he returns.
One idea could be that Naruto is resurrected in a world where all his friends have forgotten him. He has to re - establish his relationships while also dealing with a new threat that emerged in his absence.
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.
One way could be through some sort of advanced alien technology. In many super fanfics, aliens have technologies far beyond human understanding. They might be able to manipulate cells at a molecular level and bring a dead cell back to life.
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.
In this kind of fanfic, the cell could be resurrected by a magical force. Picture a world where magic and science coexist. The cell was destroyed in a normal scientific experiment gone wrong. However, a magical spellcaster senses the potential in this cell and uses magic to bring it back. Once resurrected, the cell becomes a key element in a battle between the forces of magic and science. It could hold the secret to a new form of energy that both sides want to control, and the story could revolve around the race to either protect or use the resurrected cell for their own purposes.
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.
It could be the scientist who discovers the resurrected cell. They might be a young, ambitious researcher who sees this as a once - in - a - lifetime opportunity to make a huge discovery. They have to deal with the ethical implications of the resurrected cell as well as the scientific mystery. For example, they might struggle with whether to share their discovery with the scientific community right away or keep it a secret until they understand it better.
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.
According to the plot introduction of "I Have a Lifestone", the members of the organization would have consciousness after they were resurrected. They would also provide their knowledge and strength to the protagonist. It could be said that they were very powerful. As for the other books, it was not clear if there were any members of the Akatsuki organization who were resurrected. The readers had to find out for themselves. I hope you like my answer. Muah ~
