What could be the possible plot in 'steve leaves tony and peter fanfiction'?

It could be a new villain who has the ability to manipulate minds. This villain could make Steve believe that he is a danger to Tony and Peter, causing him to leave. For instance, the villain might implant false memories or thoughts in Steve's head, making him think that his actions might accidentally harm them in the future.

The plot might revolve around how Tony and Steve adjust their lives to fit Peter in. For instance, they have to learn how to be proper guardians. They could struggle with things like setting rules for Peter. On the other hand, Peter might introduce them to a more youthful and modern side of life. Maybe they all bond over building some high - tech gadget together in Tony's lab.

Maybe Peter punches Steve because of a misunderstanding. For example, Steve might have been wrongly accused of something that Peter holds dear, like endangering his family or friends. In his anger, Peter decides to take matters into his own fists.

Maybe Peter inherits Tony's high - tech gadgets. For example, he could get access to some of Tony's Iron Man tech, which would be a huge deal. This could set him on a new path in his superhero journey, perhaps allowing him to upgrade his own suit or develop new abilities.

One reason could be Steve's long - standing friendship with Bucky. They have a deep history together, and in the fanfiction, that bond might be portrayed as stronger than his relationship with Tony. Maybe Steve feels a sense of loyalty to Bucky that he can't ignore.

One possibility is that there could be a huge ideological rift between them. Maybe Steve discovers some dark secret of Tony's that he believes endangers the world in a way that can't be resolved through normal means, leading to the extreme act of killing him.

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.

One possible plot could be that Peter has continuously disobeyed Tony's safety instructions while working in the lab or on some high - tech projects. Tony, out of frustration and a sense of responsibility, resorts to this rather extreme form of discipline. However, this kind of plot would be quite controversial and not in line with the general positive and heroic image of their relationship in the mainstream stories. It would also be a very different take on their characters, showing a more authoritarian side of Tony.

Another characteristic is the exploration of their different powers and skills within the story. Steve's super - strength, Tony's high - tech gadgets and Peter's spider - like abilities are often used in creative ways to overcome obstacles. This can lead to really exciting action sequences.

One reason could be a difference in ideology. Steve might have very traditional views and Peter's more modern or reckless approach could clash with that, leading to Steve's outburst.
