In some fanfictions where Naruto is sick, a plotline could be that his illness is caused by a new and mysterious enemy's jutsu. His body is weakened and he has to rely on his inner strength and the Nine - Tails' chakra in a different way. His friends like Sakura would be desperate to find a cure. She might use her medical skills to research day and night. Meanwhile, Naruto could be in a state of semi - consciousness, having conversations with the Nine - Tails where the Nine - Tails gives him advice on how to fight the illness, not just physically but also mentally.
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.
A possible plotline is that Naruto gets sick from overusing his powers. He's always been so eager to protect the village and his friends that he pushed his body too far. His sickness makes him vulnerable, and this could lead to a situation where some of the village's secrets are at risk of being exposed. His mentor, Kakashi, might take this opportunity to teach Naruto about the importance of balance and self - care. Also, other ninja from different villages might hear about Naruto's illness and see it as an opportunity to either help (for diplomatic reasons) or to take advantage, which could create some interesting political and action - oriented sub - plots.
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 common plotline is that Naruto's friends take care of him. For example, Sakura might use her medical skills to nurse him back to health. Another could be Naruto having flashbacks or deep thoughts while sick, perhaps about his lonely childhood. And sometimes, enemies might take advantage of his weakened state, leading to some tense situations where his friends have to protect him.
A simple plotline could be that Bella's sickness is just a normal flu, but it makes her realize how much she depends on those around her. She might have a moment of self - reflection while lying in bed sick. She could also receive some unexpected help from a stranger who turns out to be an important character later in the story.
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.
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 Lorelai being sick and Rory having to take care of her, which would reverse their usual roles. Rory might struggle to balance her own life while looking after her mom, just like Lorelai had to do when Rory was growing up.
A third plotline might be that their sickness is caused by some sort of magical or alien virus. As they fight off the illness, they also have to figure out where it came from and how to stop it from spreading to the rest of the city. This could involve some detective work even in their weakened state.
One plotline could be that Wei Wuxian's sickness is a result of a dark spell that was cast on him during one of his adventures. His friends, like Lan Wangji, then have to search for a cure while protecting him from those who might take advantage of his weakened state.
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.
