With his friends like Ned and MJ, they could be a great source of support. Ned might be fascinated by the technology of the prosthetic and try to help Peter make improvements to it. MJ, on the other hand, would see Peter's struggle and be there for him emotionally, which could strengthen their relationship as she shows her more caring side.
In his superhero relationships, the Avengers or other heroes might view him differently. Some could underestimate him at first, thinking the prosthetic will hold him back. But Peter will prove them wrong by using his intelligence and adaptability. And he might even inspire other heroes who have disabilities or injuries in the future.
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.
One idea could be that Peter Parker gets a prosthetic after a particularly dangerous battle with a villain. Maybe his leg is severely injured and he has to adapt to the new prosthetic while still maintaining his superhero duties. He could struggle at first with the balance and movement, but with his determination, he eventually masters it and even modifies the prosthetic to have some special features like enhanced jumping ability.
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 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 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.
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.
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.
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.
The Power Cosmic would have a huge impact on Peter Parker's identity. He'd have to face new challenges that are far beyond what he's faced as Spider - Man. His moral compass would be put to the test as he gains the ability to do things that were previously unimaginable. For example, he could potentially destroy entire planets if he lost control of the Power Cosmic. This would make him question his own goodness and what it means to be a hero. His identity as a hero would expand from being a local hero to a universal one, and he'd have to find a way to keep his humanity in the face of such overwhelming power.
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 also make it difficult for him to be a reliable superhero. If he's sleepwalking at random times, he might not be able to respond to emergencies in a timely manner. His allies would start to worry about his ability to protect the city.
