One common plotline is Naruto's slow recovery from a severe injury. He has to overcome physical pain and weakness, all while trying to keep his spirits up. Another is that he discovers a new power or ability while in the hospital, maybe something related to his chakra that he can only access when he's in a weakened state.
Often, in fanfiction, Naruto in the hospital can be the center of a mystery. For example, there could be strange disappearances or events happening in the hospital that only he seems to notice. He then takes it upon himself to solve the mystery, even though he's supposed to be resting. Also, there could be a love interest that comes to visit him regularly, and their relationship develops during his hospital stay.
A popular plotline is that Naruto is in the hospital due to the after - effects of a powerful jutsu he used. The fanfiction could explore how he copes with the unexpected consequences. His friends and mentors might come to give him advice on how to better control his powers in the future. And there could be a sub - plot about the hospital staff learning from Naruto's unique case to improve their medical knowledge for other ninjas.
One common plotline is the recovery of a major character. For instance, Naruto might be seriously injured in a battle and his friends gather at the hospital, waiting anxiously for his recovery. Another is the introduction of new medical techniques or characters who are medical experts.
Some fanfictions explore the idea of Naruto being betrayed by a new character introduced into the story. This new character could be secretly working for an enemy and manages to turn Naruto's closest allies against him by using their insecurities. This creates a complex web of relationships where Naruto has to fight not only the external threats but also the internal ones within his group.
Often, there's the theme of Naruto using his ninja skills for good in the hospital. For example, his ability to sense danger could help in predicting a patient's sudden decline. And his strong willpower could be an inspiration for patients to fight their illnesses. Another theme could be the relationships he forms with the other hospital employees, some might be initially skeptical of him but later come to respect his abilities.
Another theme is friendship. Naruto is a very friendly and outgoing character. In these fanfictions, he usually forms strong bonds with some of the hospital characters. For example, he might become friends with a doctor who is intrigued by his ninja abilities or a patient who he helps in a unique way.
Another theme is friendship and teamwork. Just as in Naruto where the characters rely on each other, in these fanfictions, the Naruto characters team up with the General Hospital staff. They work together to solve problems, whether it's a medical emergency or dealing with a difficult patient. It shows that no matter the universe, the power of friendship is important.
One common plotline could be Kurenai trying to keep Naruto away from certain dangerous missions. She might think he's not ready yet and be overly protective in the fanfiction.
One common plotline could be Hinata choosing someone else over Naruto, which deeply wounds him. Another might be Hinata lying to Naruto about something important, causing him emotional distress. There could also be a plot where Hinata physically harms Naruto in a moment of being controlled or influenced by some external force.
In some Naruto break - up fanfictions, the break - up might occur because of a third party. For instance, a new character enters the picture and causes a rift between Naruto and his partner. It could also be that Naruto's own personal growth and change in values lead to the break - up. As he becomes more in - tune with his inner self and his goals as a ninja, he may find that his relationship no longer aligns with his new vision of life.
Many fanfictions focus on the power - up of the characters. Naruto, Sai and Sasuke might go on a training journey together. During this journey, they face various challenges that test their skills and their relationships. There could also be a plotline where an old enemy resurfaces and targets the three of them specifically. They then have to put aside their differences and combine their abilities to defeat the enemy. This often leads to character growth for all three, especially for Sasuke who may have to finally accept his place among his comrades.
One common plotline could be a family member being influenced by an enemy. For example, a relative might be controlled by Orochimaru and turn against the family. Another could be a misunderstanding within the family. Maybe Naruto is wrongly accused of something by his family and they turn their backs on him. There could also be a power - hungry family member who betrays the family to gain more power or status in the ninja world.
