Well, one possibility is that his loved ones might be in danger. The bad guys could target them to get to Spider - Man. For example, Mary Jane could be kidnapped. Another thing that could occur is that the public's perception of him changes. Some might see him as a hero, but others could fear his power. Also, his friends might feel betrayed that he kept this big secret from them all this time.
Perhaps in this fanfiction, Spider - Man's revelation of his identity leads to a new wave of self - discovery. He no longer has to hide who he is, so he can explore different aspects of his life. He might use his real name, Peter Parker, to start a new scientific project that could help the city in a different way than just fighting crime as Spider - Man. His relationships with his colleagues at work or school could also change drastically. Some might idolize him, while others might be jealous of his dual life.
Well, one possibility is that Mary Jane is initially shocked but then realizes she can use her own skills, like her acting abilities, to help Spider Man in his fight against villains. For example, she could pretend to be in danger to lure out bad guys. Another aspect could be that their relationship becomes more public, which might have both positive and negative impacts on Spider Man's secret identity.
Another thing that could occur is that the public's perception of him would change drastically. Some might see him as a hero, but others could fear him or be angry that he's been hiding his identity all this time. There could be protests or demands for him to be regulated in some way.
The story could develop in many ways. For instance, his enemies might become more cautious. Since they know who he is, they might plan more elaborate traps. On the other hand, Spider - Man could use his new - found openness to his advantage. He could start a public campaign to fight crime, inspiring others to join him. This would make the city a more united front against evil. Also, his family might get involved in his superhero activities more directly, either to support him or to try and stop him for fear of his safety.
The villains in the fanfiction would surely take advantage of this situation. They could target Spider - Man's loved ones, like Aunt May. Maybe the Green Goblin would plan a big attack on Spider - Man's home, knowing that he now has the upper hand with Spider - Man's identity out in the open. And Spider - Man himself would have to be extra cautious and might even consider leaving the Avengers to protect them.
Well, one thing that could happen is that Peter Parker's friends might be in shock. They could feel betrayed that he didn't tell them earlier. Some might be scared for his safety as they now know he's constantly in danger as Spider - Man. And the school might become a target for his enemies who find out where he spends a lot of his time.
Well, the public's reaction would be a huge factor. Some might see him as a hero, but there would also be those who fear his powers. Maybe the media would start hounding him, like they did with Superman in some stories, constantly asking for interviews and trying to dig up dirt on his personal life.
One possibility is that Merlin's revelation of his magic could lead to a change in his relationships. For example, his friends who were previously unaware might react with shock, some with fear and some with acceptance. His enemies, on the other hand, would likely see him as an even greater threat and might plot more vigorously against him.
Another possibility is that a new member of the Avengers might suspect Spider - Man's identity and start investigating. This could create a lot of tension within the team as Spider - Man tries to keep his secret while the other member gets closer to the truth. It could also lead to a sub - plot where the Avengers are divided on whether to respect his privacy or force him to reveal his identity if they think it's a threat to the team.
In fanfiction, if Scarecrow reveals Batman's identity, it could shatter the public's perception of Bruce Wayne. People might see him as a vigilante who has been deceiving them all along. This could lead to a division in Gotham, with some seeing him as a hero still and others believing he's a menace. Batman's allies, like Commissioner Gordon, would have to decide whether to continue supporting him or distance themselves to protect their own reputations.
If the Avengers find out Spider - Man's identity in fanfiction, they could use his civilian life to their advantage. For example, they might ask Ned Leeds, Peter's friend, to help them out with some tech - related stuff since he's good at that. Or they could station some Avengers near his school or his home to keep a closer eye on him. However, this might also put Peter's loved ones in danger as his enemies could figure out where he lives and who he cares about.
