In the fanfic, it might be set in an alternate universe where Sakura has a different personality. She could be more aggressive and competitive with Naruto. During a sparring match, she goes too far and seriously hurts Naruto. This could then be the starting point of a story about Naruto having to forgive her and them rebuilding their friendship.
A plot could involve Sarada getting hurt in a trap set by a villain. The villain might be targeting the new generation of ninja in the village. As she gets injured, it sets off a chain of events where her friends start to investigate the incident. Sarada, while hurt, could provide some crucial clues from what she saw before getting injured. This would not only be about her physical injury but also about her mental strength as she tries to contribute to the solution while in pain.
One possible plotline could be that Naruto gets an eye transplanted from an Uchiha. This new eye might give him the ability to use Sharingan techniques. He could struggle at first to control it, like Sasuke did when he first awakened his Sharingan. It might also change his perception of the ninja world, as he now has a power that was once exclusive to the Uchiha clan.
One possible plotline could be that Sakura, perhaps under the influence of some dark force or a misunderstanding, physically attacks Naruto. This could be due to a false belief that Naruto has done something terrible to their village or friends. Another plotline might involve Sakura's words hurting Naruto deeply. For example, if she tells him that he will never be good enough or that she doesn't really consider him a true friend after all. It could also be that Sakura's actions in pursuit of Sasuke end up causing Naruto pain indirectly, like if she constantly ignores Naruto's feelings for her while she chases Sasuke, making Naruto feel unimportant and hurt.
One possible plotline could be that Naruto leaves the village due to some sort of political unrest. He meets a girl from another land during his travels. They bond over their shared experiences of being outsiders in a way. As they travel together, they face various challenges like bandits and natural disasters. Their relationship deepens through these hardships and they eventually decide to get married. It could also involve Naruto teaching his new partner about the ninja way.
One common plotline could be Naruto facing a powerful enemy alone to safeguard Sakura. For example, in a fight against a rogue ninja who has a vendetta against Sakura's medical skills, Naruto jumps in front of an attack meant for her. This could lead to him getting seriously injured and Sakura having to use her medical ninjutsu to save him while also realizing her true feelings for Naruto.
A plotline could revolve around Sakura trying to understand Tsunade's past more deeply. Tsunade might be reluctant at first, but as they work together more closely, she starts to open up. This could lead to Sakura learning important life lessons from Tsunade's experiences, like how to deal with loss and keep going. They could also get into a situation where they have to use their combined medical and combat skills to save a group of injured ninjas.
In a fanfic where Dawson gets hurt in Chicago Fire, it could start with a routine call that turns dangerous. Let's say there's a gas leak explosion and Dawson is caught in the blast. Her colleagues would be in a state of shock and panic. They'd quickly try to assess her injuries and get her to the hospital. At the hospital, there could be a waiting game as they all hope for her recovery. Her injury might also make her question her future in the firefighting profession. Some of her friends might encourage her to keep going while others might be more hesitant, thinking she's been through enough. This conflict among her friends and her own internal struggle could form the basis of the fanfic.
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.
One possible plotline could be that Naruto is granted wings as a result of some ancient and powerful jutsu he accidentally activates. With the wings, he could gain new abilities like enhanced speed in the air and new combat techniques. For example, he might be able to use the wind generated by his flying to create more powerful Rasengan attacks. Another plotline could be that the wings are a gift from a mysterious being who sees Naruto's pure heart and wants to help him in his fight against evil. He then has to learn to control the wings and use them to his advantage in battles against stronger opponents.
One possible plotline could be that Harry gets hurt during a Quidditch match. Maybe a Bludger hits him hard and he has to deal with a serious injury like a broken bone. He then has to struggle with not being able to play for a while and the fear of not being as good when he recovers.
