Well, in terms of his relationships, if Peter is homeless, it can have a huge impact. His Aunt May, if she's still around in the fanfiction, would be extremely worried about him. But Peter, being the independent and self - sacrificing type, might not want to burden her. With his superhero friends, if he has any in the story, they might not understand at first why he's being so secretive about his living situation. This could lead to some friction until he finally opens up. And his enemies might try to use his homelessness against him, for example, by trying to expose his situation to the public to undermine his reputation as Spider - Man.
His homelessness can be a major factor in his relationships. His friends at school might start to notice that he's always tired, dirty or wearing the same clothes. This could lead to them being curious and asking questions that Peter is not ready to answer. His relationship with the police or other authorities could also be affected. They might suspect him of being up to no good because he's homeless. On the other hand, he might form new relationships with other homeless people. These relationships could be both a source of support and a complication, as he has to balance his newfound friendships with his secret identity as Spider - Man.
His relationship with his friends like Ned and MJ could become strained. They might not understand why he's so distant all of a sudden and why he always seems to be in a hurry. Peter would be constantly worried about them finding out he's homeless and might push them away to protect his secret.
It affects his ability to be Spider - Man. Without a stable home, he has no place to keep his suit or his web - shooters. He might have to carry them around all the time, which could be risky. Also, it can make him more vulnerable mentally. He's used to having a home and a family (even if his aunt may be struggling too), and now being homeless can be a huge blow to his confidence.
It could strengthen his relationship with Tony Stark. Since Tony already had a mentor - like relationship with Peter, this new level of honesty might make them even closer. Tony could become more protective of Peter, seeing him as not just a protege but also a true member of the Avengers.
His relationship with Aunt May could become more complex. She might be overly worried about him and his ability to cope with the prosthetic. There could be a lot of tender moments where she tries to take care of him more than before, which Peter might initially resist as he wants to be independent.
It could strain his relationship with Aunt May. If he starts to show strange symptoms after the bite, like growing extra arms or having a strange craving for bugs, Aunt May would be very worried. She might think he is sick or involved in something dangerous.
His relationship with Morgan herself could also be affected. He might not be as kind to her as he should be. Instead of seeing her as a little girl who just happens to be in a situation where she gets a lot of attention, he could start to resent her, which would make their interactions awkward and uncomfortable.
Peter's relationship with Flash could be a source of drama. Flash could be trying to upstage Peter at graduation, but then when trouble strikes, Peter has to save Flash without revealing his identity. And his relationship with the other Avengers (if it's set in that universe) could also play a part. They could send him a special message or gift for his graduation, showing their support for his civilian life as well as his superhero one.
His relationship with his aunt May could become more strained. She might be constantly worried about his safety now that his identity is known. There could be a lot of arguments about him continuing to be Spider - Man.
His relationship with MJ would likely become more protective. MJ might worry more about Peter and be more involved in his day - to - day life. She could also be his eyes in certain situations, like describing the layout of a new place or a new threat. With Ned, Ned would probably be more hands - on in helping Peter with technology. He might modify Peter's web - shooters to have more audio or tactile feedback.
Well, in some fanfictions, Peter Parker's spider - based powers could potentially give him an enhanced thermoregulation ability. His metabolism might be faster due to his powers, which could help him generate or dissipate heat more efficiently. For example, if he's in a cold environment, his body could quickly produce more heat to keep him warm, much like how a real spider can adjust its body temperature to some extent.
