One great 'Naruto gets sick' fanfic is 'Ailing Naruto' on FanFiction.net. It shows how the village comes together to take care of him when he falls ill from a mysterious disease. Another one is 'Sick Day for Naruto' on Archive of Our Own. In this fic, Naruto's friends, like Sakura and Sasuke, try their best to nurse him back to health. And there's also 'When Naruto is Under the Weather' which focuses on how Naruto's illness affects his training and his relationship with his sensei, Kakashi.
I really like 'Naruto's Sick Struggle'. In this fanfic, Naruto gets a really bad cold that he caught during a mission in a rain - soaked forest. His chakra is all messed up because of the illness, and he can't perform his usual jutsus. His friends are super worried, especially Hinata who brings him special herbal teas to help him get better. It's a really heart - warming story about friendship and care. There are also other fanfics where Naruto gets sick due to some poisoned food he ate at a local inn during his travels.
Well, 'Naruto's Sick Adventure' is an interesting one. Naruto gets sick from over - exerting himself during a major battle. He has a high fever and is delirious. The story then shows how the medical ninjas in the village, led by Tsunade, try different remedies to cure him. Some of the remedies are based on ancient ninja medicine that has been passed down for generations. Meanwhile, Naruto's friends keep him company and tell him stories to keep his spirits up while he recovers.
One great fanfiction could be 'Damian's Sick Day'. It focuses on how the Bat - family takes care of Damian when he falls ill. They show their love and concern in different ways, like Alfred preparing special soups and Bruce staying by his side when he has nightmares due to the fever.
There's a fanfic titled 'When Hermione Falls Ill'. In this story, it focuses on Hermione's internal struggle while being sick. She's not used to being incapacitated and it delves into her thoughts and how she copes. It's really interesting as it gives a deep look into her character even when she's not at her best. For example, she tries to continue her studies while sick but her body just won't allow it.
The fanfic could explore how Sasuke deals with his emotions when Naruto is sick. He might be conflicted between his old rivalry feelings and his newfound, deeper feelings for Naruto. Sasuke could also be the one to stay by Naruto's side when everyone else is busy. He'd watch over Naruto while he sleeps, and when Naruto wakes up, there could be a moment of intense eye - contact that shows the unspoken bond between them.
One idea could be that Sasuke, despite his usually stoic nature, feels a sense of worry when he hears Naruto is sick on his birthday. He could visit Naruto and bring him some traditional Uchiha herbal medicine that he secretly prepared. This would show a soft side of Sasuke and also deepen their bond in the fanfic.
One great 'Hermione gets hurt' fanfic is 'Bruised but Not Broken'. It shows Hermione getting injured during a battle at Hogwarts. The author does a wonderful job of portraying her pain and the concern of her friends. Another is 'Injured in the Line of Magic' which focuses on how Hermione's injury affects her studies and relationships. It's a really interesting take on the concept.
One plot could be Naruto getting a mysterious illness that no one in the village can figure out. His friends, like Sakura and Sasuke, start to search for a cure. They might go on a journey to find a rare herb or seek the help of an old sage. Another could be that the illness is a result of a new enemy's jutsu. As he gets sicker, the village starts to worry about their future without their hero.
One possible plot could be that Naruto's friends have to take on his missions while he is sick. They struggle at first because they realize how much Naruto usually does. Another could be that Naruto tries to hide his sickness from everyone, but his body keeps giving him away, like fainting during training. And a third plot might be that a new enemy takes advantage of Naruto's weakened state to attack the village.
His teammates, Sasuke and Sakura, would surely be involved. Sasuke, although he may not show it as much, still cares about Naruto. He would keep an eye on Naruto's condition, and if there was any sign of danger, he would be ready to protect him. Sakura would be more hands - on with the medical care, checking his temperature, giving him medicine, and making sure he rests properly.
One great 'Harry gets sick' fanfiction could be 'Under the Weather'. In it, Harry catches a strange magical illness that has everyone worried. It's a really interesting take on how the Hogwarts staff and his friends react to his weakened state.
One interesting Naruto gets Ice Release fanfiction could be where Naruto discovers this power during a hidden mission in a frozen land. Maybe he meets an ancient spirit that grants him this ability as a way to survive the harsh cold and then he has to learn to control it quickly to fend off enemies. Another could be a story where he inherits the Ice Release from an unknown bloodline within the Uzumaki clan that has been dormant for generations.
