A great plotline in Naruto - is - revived fanfiction could be that Naruto returns not just as himself but as a vessel for an ancient and powerful spirit. This spirit has its own goals and agenda, which may or may not align with Naruto's original values. He then has to struggle between his own identity and the will of the spirit within him. His friends initially don't know what to make of this new Naruto and he has to prove that he's still the same person at heart.
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.
Another plot could involve Naruto being revived due to the strong will of the people. In the Naruto universe, the will of the people can have a strong influence. So, all the people who Naruto has helped and inspired over the years unconsciously create a kind of spiritual energy. This energy is noticed by a sage or some other powerful being who uses it to bring Naruto back. Once revived, Naruto uses his new - found spiritual connection with the people to fight an even greater evil.
Another plotline could involve a new character who befriends Sasuke. Naruto, being the competitive and close friend that he is, might get jealous of their budding friendship. This could lead to Naruto trying to insert himself into their activities and causing some comical or tense situations.
One possible plotline could be Naruto protecting his younger sibling from the threats of rogue ninjas. He would use his skills and influence in the ninja world to keep them safe, perhaps even training them secretly to ensure they can defend themselves. Another plotline might involve Naruto dealing with a political situation where his sibling is in danger due to their relation to him. He has to navigate the complex world of ninja politics to safeguard his family.
One interesting plotline could be their journey of understanding each other's past traumas. Gaara was once alone and feared, while Naruto was ostracized. They could bond over how they overcame those difficult times and became stronger. Their relationship as mates could be shown through their mutual support in battles and in dealing with the politics of the ninja world. For example, when facing threats from other villages, they stand side by side, using their combined skills to protect their own village and the new bond they share.
Perhaps there's a plot where Naruto is framed for a crime that could lead to his expulsion from the ninja world. Gaara, believing in Naruto's innocence, launches an investigation on his own. He uncovers the real culprits and presents the evidence to the ninja council, all while protecting Naruto from any harm that might come his way during the process. Gaara's protective nature also extends to Naruto's emotional well - being. When Naruto is feeling down about not being able to achieve a certain goal, Gaara is there to offer words of encouragement and support.
Maybe in the fanfiction, Naruto is found by Tsunade while he's on a secret mission. Tsunade helps him complete the mission and in the process, discovers a hidden power within Naruto that he didn't know he had. This new power could be related to the Uzumaki clan's sealing techniques, and Tsunade helps him master it, changing the course of Naruto's battles in the future.
In a fanfiction, Naruto and Hinata as friends could go on a journey to find a rare flower that has the power to heal serious injuries. They encounter various obstacles like dangerous terrains and wild animals. Hinata might use her tracking skills with the Byakugan to find the right path, and Naruto would protect them from any immediate threats. As they travel, they talk about their dreams and fears, deepening their bond of friendship.
One interesting plot could be Naruto coming back with new and enhanced powers. Maybe he has a special connection to a new chakra source that was unknown before his revival. This would make him even more powerful and able to face new threats that emerged during his absence.
One consequence could be that Naruto has some strange side - effects. Since Orochimaru's methods are often unorthodox, Naruto might have trouble controlling his chakra properly. For example, his chakra could be tainted with some of Orochimaru's dark chakra, making his jutsu less stable.
