In this type of fanfiction, the emotional impact on the characters is crucial. For Peter, his relationship with Tony was like a father - son bond. With Tony's death, he might isolate himself from his friends at school, feeling like he doesn't belong in the normal world anymore. In the superhero community, there could be a power vacuum. Characters like Doctor Strange or Captain Marvel might step in to help Peter fill that void. And Peter's journey to come to terms with Tony's sacrifice could involve him traveling to different dimensions or timelines to find a way to bring Tony back, even if it ultimately fails.
One possible plot development could be that Peter is left with a huge sense of guilt. He might struggle with survivor's guilt, constantly thinking that it should have been him. He could then become overly reckless in his superhero activities, trying to prove that he was worthy of being saved. Another aspect could be how the other Avengers deal with Tony's death. They may turn to Peter as a symbol of hope, since Tony sacrificed himself for Peter. This added pressure on Peter could lead to him either rising to the occasion or crumbling under it.
Well, in such a fanfiction, perhaps the technology that Tony left behind would be a major plot point. Peter, being the tech - savvy kid he is, might try to inherit and further develop Tony's tech. He could face challenges from villains who see this as an opportunity to steal the tech. Also, Pepper could play an important role. She might take Peter under her wing, seeing him as a connection to Tony. This could lead to a really interesting dynamic between them, with Pepper guiding Peter not just in the superhero world but also in dealing with the loss of Tony.
One possible scenario in such a fanfiction could be that Peter, in a self - sacrificing move, takes on a powerful enemy that was originally meant to target Tony. Maybe Peter's inexperience and pure heart lead him to misjudge the danger, and he ends up giving his life to save others, while Tony is left to grapple with the guilt.
In this fanfiction, it could be that Peter snaps after Tony makes a decision that Peter strongly disagrees with. Let's say Tony decides to sacrifice a certain group of people to save the majority in a moral dilemma. Peter, who has a stronger sense of justice for the individual, snaps and decides to go against Tony's plan. He then has to fight not only the external threat but also deal with the rift he has created within the team.
The other demigods at Camp Half - Blood would also be in chaos. Percy was like a leader to many of them. His death could lead to a lack of confidence among the younger demigods. Some might even start to question the protection of the gods. Zoe's survival could also lead to her taking on a more prominent role in guiding and protecting the demigods, which is a big change from her previous situation.
A possible plot development could be that Peter is initially shocked by Tony's confession. He might not know how to respond at first, leading to some awkward moments between them. Then, they could gradually grow closer and form an even stronger alliance.
Peter's character arc would take a very dark turn. He'd likely be consumed by grief and a sense of obligation. His once - carefree and enthusiastic approach to being a superhero would be replaced with a more solemn and determined one. He might become more secretive, not wanting to let others in on his pain.
The story could focus on Tony's downward spiral into guilt and self - blame. He might isolate himself from the other Avengers, feeling that he should have been the one to die. His technological advancements could take a dark turn as he tries to find a way to bring Peter back, perhaps even dabbling in dangerous and unethical science.
One possible plot development could be that Voldemort fully regains his power without Harry as an obstacle. The wizarding world would be plunged into complete darkness. His friends, like Hermione and Ron, might go into a deep state of despair and then form a resistance group. They would try to find other ways to defeat Voldemort, perhaps by seeking out more powerful magical artifacts or uniting with some previously neutral magical creatures.
One possible plot development could be how the wizarding world reacts to the loss of the so - called 'Chosen One' even as a baby. There might be widespread grief and fear among those who opposed Voldemort, as they had placed so many hopes on Harry. Another aspect could be how Voldemort's reign of terror continues without the threat of Harry Potter. He might become even more powerful and tyrannical, with no one to oppose him in the way Harry was prophesied to.
One possible plot development could be that his death shatters the Straw Hat crew. They might disband in grief, each going their own way. Zoro could become consumed with revenge, vowing to take on the Marines who were responsible.
One possible plot development is that Tsunade could step up her efforts in uniting the other villages. Since Naruto was a symbol of hope and unity, his death might prompt Tsunade to work even harder to prevent further chaos among the ninja villages. She could initiate more diplomatic meetings and treaties to ensure peace in Naruto's memory.
