Well, if Spider - Man is amnesiac, he may accidentally reveal his identity. Since he doesn't remember who he is, he might do things that expose his secret. For example, he could be in his Spider - Man suit and not know why, and then be careless around people. His relationships would also be affected. He might not recognize his friends and push them away. This would cause emotional distress for both him and his friends. Plus, the villains could use his amnesia to create chaos in the city. They could frame him for crimes he didn't commit while he was in a confused state.
One consequence could be that the city he protects would be in more danger. Without his memory, Spider - Man might not respond to crimes quickly or at all. Another consequence is that his loved ones would be worried and confused. They would have to try to figure out how to help him regain his memory. Also, his enemies could take advantage of his amnesia to launch more attacks or manipulate him.
The consequences are quite serious. Firstly, Spider - Man's sense of purpose would be lost. He has always been about protecting the weak and fighting crime. Without his memory, he may not feel that drive. This could lead to a rise in crime rates in New York City. Secondly, his personal life would be in shambles. His relationships with Mary Jane, Aunt May, and his friends would be strained. They would be constantly trying to help him, but he might resist or be confused by their efforts. Thirdly, the superhero community would be affected. Other heroes might have to step in to cover for him, and there could be a power vacuum that villains would try to exploit.
Once, Spider - Man got hit on the head during a battle with a powerful villain. When he woke up, he had no memory of who he was. He wandered the streets, confused. He didn't remember his powers or his responsibility to protect the city. As he walked, he saw a little boy in trouble, being bullied by some thugs. Instinctively, his body moved to protect the boy, and he found himself using some of his powers without realizing it. This small incident started to trigger little memories, and slowly he began to piece together his identity as Spider - Man.
The experiment could also make him an outcast. If the changes are too extreme, his friends and the public might be afraid of him. He would have to deal with the loneliness and the struggle to prove that he is still the same Spider Man at heart, just with some new abilities or features.
The possible consequences of the Spider - Man: No Way Home story being leaked are numerous. For the fans, it can really dampen the excitement of the movie - going experience. Imagine looking forward to a big blockbuster like this and then finding out key plot points before you even step into the theater. It takes away the element of surprise. For the studio, as mentioned before, it can mess with their marketing. They might have planned a big reveal for a certain plot twist, but if it's already leaked, that surprise is ruined. And in terms of the overall perception of the movie, if the leaked story is negative, it can create a pre - conceived notion in the minds of the audience that might be hard to shake off, even if the actual movie is great.
There could be a redemption arc in the fanfiction. Spider - Man might work hard to prove himself and clear his name. He could start by taking on smaller threats and gradually build his reputation back up. This might involve him saving the day in a very public way, which catches the attention of the Avengers again. Eventually, he could be reinstated into the team, but with a new - found respect for the importance of trust and loyalty within the group.
One reason could be that he gets tired of the constant danger and the toll it takes on his personal life. He might have lost too many loved ones due to his superhero identity, and he just can't bear the pain anymore.
There could be a new villain emerging in Spider Man 4 story. Maybe it's someone from Peter Parker's past, like an old classmate who got exposed to some strange experiment and turned into a super - powered foe. Spider - Man would then have to figure out how to defeat this new threat while also dealing with his normal life issues, like his job at the Daily Bugle and his relationships.
There could be Spider - Man saving a Santa Claus who got into trouble. Maybe Santa's sleigh crashed in the city and Spider - Man had to use his webs to fix it and help Santa deliver the remaining presents.
It could involve Spider-Man fighting off a powerful villain to save the city. Maybe a new threat emerges that challenges his powers and his determination to protect the people.
He could become more withdrawn. Losing Aunt May, who was like a mother to him, would be a huge blow. He might isolate himself from his friends and even from his crime - fighting duties for a while as he deals with his grief.
One possible consequence could be a change in self - perception. Just like in the previous stories, the person might start to view themselves in a different way, which could last even after the hypnosis ends. For example, they might be more open to activities or interests that are typically associated with girls.
