There are also fanfictions where his attempt is not successful, but it has consequences. He might end up in a hospital, and then have to deal with the fallout of his actions. People around him might be angry, sad, or confused, and he has to face their reactions while also trying to figure out how to move forward and get better.
One reason could be extreme guilt. Maybe he failed to save someone important and can't bear the burden of that failure. In some fanfictions, if he accidentally caused harm to his loved ones, like Aunt May getting hurt because of his superhero activities, the guilt might be overwhelming.
Peter Parker doesn't kill MJ in the comics. This is a misconception.
Typically, a Peter Parker identity reveal fanfiction starts with the moment of the reveal itself. It could be due to an accident, like his mask getting ripped off in a big battle. Then, it often shows the immediate reactions of the people around him, like shock from his friends or anger from his enemies. After that, it may explore how Peter has to adapt to this new situation, such as dealing with the media or new threats that come his way because his identity is known.
In the fanfiction, Peter Quill Parker might have some new powers or gadgets that give him the edge. He could have studied Thanos' fighting patterns and found a way to counter them. Also, his quick thinking and ability to improvise in tough situations would play a big role. He might even use his charm to get close to Thanos and then strike when he least expects it.
Often, it shows his growth in terms of technical skills. With the resources and mentorship at Stark Industries, Peter becomes more proficient in building and modifying his gear.
It might handle it by showing the psychological state of Paul very clearly. Through his internal monologues, the readers can understand his pain and desperation. For example, it could describe how he looks at his Pokemon team and feels like he has let them down, which adds to his sense of failure.
His friends would likely be in shock. Sasuke, for instance, might be deeply affected as Naruto is his closest rival and friend. He could initially be angry at Naruto for being so reckless, but then feel a deep sense of loss.
Peter could also respond with guilt. If the accusations hit close to home, like being a liar, he might feel bad and start to question his own actions. This could lead to him trying to be more open or finding a better way to balance his two lives.
Often, his friends start to search for him. His best friend Ned might use his tech - savvy skills to try and track him down. They might follow some leads that Peter left behind, like a special code or a hidden message.
It could end with Peter realizing his mistake and apologizing sincerely to MJ. He might open up about everything and they reconcile, with MJ forgiving him.
