Often, in such fanfictions, Naruto is trained in special forms of chakra control. This could involve things like using chakra to enhance his senses far beyond normal levels. It might also include training in stealth and infiltration, skills he didn't focus much on before. So, the plot could revolve around him becoming a more well - rounded ninja in these aspects.
One common plotline could be Naruto's friends rallying around him. For example, Sasuke might put aside their differences and visit Naruto while he's sick. He could bring some special herbs or medicine that he found during his travels. Another plotline could involve Naruto having a fever and having strange dreams about his past and future. In these dreams, he might see visions of his parents or get premonitions about threats to the village. And sometimes, the story could focus on how the village itself copes with Naruto being sick. The villagers who once shunned him might now realize his importance and come together to support him in his time of need.
Often, in these fanfictions, Naruto is betrayed by Sasuke again in a different way. Sasuke might side with a new group that has a vendetta against Naruto or Konoha. This could lead to some epic battles where Naruto is not only fighting his former friend but also trying to understand why he has been betrayed. It also gives room for Naruto to grow and develop new powers as he faces this new challenge alone.
Another plotline might involve Naruto's friends betraying him. Suppose Sasuke, out of his thirst for power and a twisted sense of rivalry, teams up with some dark forces against Naruto. This would create a lot of emotional turmoil for Naruto as he has always considered Sasuke a brother.
Another plotline could involve Naruto being injured as a result of a trap. Maybe he's exploring an ancient ruin in search of some power to help protect the village and he triggers a hidden mechanism. This could lead to him being severely wounded, and his friends would need to come rescue him while also trying to figure out how to disarm any other potential threats in the area.
Some fanfictions might show Naruto's mental state while sick. He could be feeling down and doubting his ability to protect the village. However, the villagers, who once shunned him, now come together to support him. This change in the villagers' attitude could be a key part of the plot, as Naruto realizes that he has truly become an important part of the village even in his weakened state.
One possible plotline could be that Itachi sees Naruto's potential even at a young age. He might start teaching Naruto basic ninja skills like stealth. For example, Itachi could show Naruto how to move quietly in the forest without making a sound. This early training could give Naruto an edge when he later enters the academy, as he would already have a foundation in some ninja arts.
One common plotline could be Hermione using her skills as a trained soldier to defend Hogwarts. She might lead a group of students in a battle against dark forces, using her strategic knowledge. Another could be her being sent on secret missions outside of Hogwarts to gather intelligence or rescue captured allies. For example, she could use her intelligence and combat training to infiltrate a Death Eater stronghold.
Well, in fanfiction, Naruto being trained in different ways can bring more variety to his character. He can be trained in unique fighting styles or gain knowledge that was not available in the original story. This can make him more versatile in different storylines. Also, it can attract more readers who are looking for new and exciting takes on Naruto's development.
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 plotline could be Naruto's struggle to keep up in his ninja training due to malnourishment. His body might not be as strong as his peers', so he has to find ways to overcome this, like secretly foraging for food or relying on the kindness of some villagers who see his plight. Another could be that his malnourishment is a result of being ostracized, and as he tries to improve his situation, he also starts to question the village's treatment of him.
