Peter's relationships can also be developed. His friends could come to visit him when he's sick. He might be more open with them about his insecurities as Spider - Man. And his enemies might take advantage of his weakened state, which forces him to grow and find new ways to defend himself even when he's not at his best.
One common plot is that Peter's friends and family take care of him. For example, Aunt May might fuss over him, making him soup and ensuring he takes his medicine. Another plot could be Peter trying to hide his sickness while still being Spider - Man. He might struggle to keep up with his superhero duties while feeling unwell.
A sick Peter Parker fanfiction often has a different kind of pacing. Instead of the fast - paced action we usually associate with Spider - Man stories, it slows down. We get to see Peter's internal thoughts more. He might be frustrated with his body not cooperating. And the way the author writes about his attempts to get better, whether it's through rest or some super - sciencey solution, all contribute to making it an interesting read.
Perhaps Peter's sickness is a result of his overuse of his powers. The Avengers, especially Tony Stark, feel responsible. They start by quarantining Peter in the Avengers Tower. Then, they call in all their medical and scientific resources. They might discover that the only way to heal him is for Peter to temporarily give up his powers, which would be a huge struggle for him.
Some dedicated Spider - Man fan communities may also have a collection of such fanfictions. You can join these communities, introduce your search for Peter Parker sick fanfiction, and ask for recommendations from the members. They might be able to point you to some great reads that you may not find easily through general searches.
Peter could be really worried about his identity being revealed while he's sick. His weakened state might make it harder for him to control his powers. What if he accidentally shoots a web in the middle of the classroom? He'll have to be extra careful, and this internal struggle could add a lot of interesting drama to the fanfiction.
The Avengers would initially be in shock when they find out Peter is sick. Clint Barton would be the one to keep a calm head and start organizing things. Wanda Maximoff would try to use her powers to ease Peter's pain if possible. Vision would use his vast knowledge to try and find a solution. They would all be very concerned and do everything they can to make Peter better, from getting the best medical help to providing a safe and comfortable environment for him to recover.
Another idea is that Peter is sick and hallucinating. He starts seeing alternate versions of himself from different universes. These versions are trying to tell him something important about his powers or a future threat. But because he's sick, it's hard for him to distinguish between what's real and what's just a fever - induced dream.
There's a fanfiction called 'Sick Day for the Web - Slinger'. It shows Peter in a more human light when he's sick. He can't do all the amazing acrobatics and stunts he usually does. It focuses on his recovery process and how the people around him support him during this tough time.
There's a fanfiction titled 'Sickly Spidey' that's quite good. It delves into how Peter's sickness affects not only his physical abilities but also his mental state. It shows his vulnerability in a way that's different from when he's just facing villains. The author does a great job of portraying his struggle to get better while still being the friendly neighborhood Spider - Man.
