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.
Another aspect could be isolation. Peter often keeps his identity a secret, and this can lead to a great sense of loneliness. If in a fanfiction he feels like he has no one to truly talk to or connect with about his dual life, he might sink into despair and consider taking his own life. He's constantly juggling normal life and superhero duties, and if he feels he can't handle it anymore, that could be a trigger.
Well, one reason could be that he's on a secret mission for S.H.I.E.L.D. that requires him to go undercover and cut off all contact. Maybe he's investigating a new super - villain threat that's too dangerous to let anyone know about.
He might think it's not in line with the real Steve. Fanfiction can be quite far - fetched sometimes.
Well, it might be an exploration of the psychological toll of being a superhero. Peter Parker constantly faces danger, loss, and has to keep his identity a secret. Writers may create 'suicidal peter parker fanfiction' to show how all these factors could potentially break him. Also, in the context of fanfiction, it could be a way to subvert the typical heroic narrative and show a more vulnerable and broken side of the character. However, it's a very heavy and potentially triggering topic.
It could also be a way to subvert the typical superhero narrative. Usually, superheroes are invincible and always triumph. By writing about Peter Parker committing suicide, it challenges the norm and makes readers think about the fragility of even the most iconic characters. It forces the audience to consider the toll that being a hero can take on a person's mental and emotional state.
Some writers might do it for shock value. They want to create a very different and extreme take on the character to get a strong reaction from readers.
Maybe it's due to a new and powerful enemy's attack. In fanfiction, authors might create unique villains with abilities that specifically target Peter's weaknesses. For example, if the villain has the power to disrupt Spider - Man's enhanced senses, it could cause Peter to be disoriented and ultimately collapse. Another aspect could be that Peter overuses his powers without proper rest, which exhausts his body and causes him to collapse.
There are several possible reasons. Firstly, it could be a way to add a new layer of complexity to Peter's character. If Pepper is his mom, it might change his relationship with the Stark family and the Avengers in different ways. Secondly, it could be a creative way to rewrite the Spider - Man origin story. With Pepper as his mother, Peter might have access to different resources and knowledge earlier. And finally, it could be a form of wish - fulfillment for the writer, who wants to see these two beloved Marvel characters connected in a family - like way.
One possible reason could be extreme exhaustion. Peter Parker has a double life as a student and Spider - Man. He might be overworked, not getting enough sleep, and his body just gives out. For example, he could have been fighting multiple villains in a row without a break.
Maybe in the fanfiction's universe, the rules for obtaining the Soul Stone are different. It could be that the Stone demands a sacrifice of someone with a pure heart like Peter, and Tony, in his desperation to stop an even greater evil, makes the ultimate sacrifice. Another reason could be that Tony is being manipulated by some dark force. This force convinces him that killing Peter for the Soul Stone is the right thing to do, and Tony, believing he is doing the greater good, goes through with it.
One possible reason could be a difference in ideology. Maybe Peter Parker feels that Stark's methods are too extreme or not in line with his own moral compass. For example, Stark might be involved in some projects that Peter doesn't agree with, such as using certain unethical technologies in the pursuit of justice.
