One possible plot is that Tony begins to set up a trust or some sort of legal arrangement to ensure Peter inherits his assets and responsibilities. Along the way, Peter might struggle with the weight of this new role. He's still a young kid, after all, trying to balance school, his normal life, and now this huge expectation of being Tony's heir. There could be conflicts with other characters who either envy Peter or think he's not ready for such a big role.
Obviously, Tony Stark and Peter Parker are the main characters. Tony is the one making Peter his heir, so he'll be a central figure in guiding Peter and setting things up for him.
Well, it could be that Tony, seeing Peter as a son - like figure, leaves him something very special in his will. Maybe it's his high - tech suit technology, which would help Peter continue his superhero journey in a more advanced way.
The plot could start with Tony noticing Peter's potential but also his limitations with his current gear. So, he decides to make Peter an Iron Suit. Peter is initially in awe of the new suit and has to learn how to use all its functions. There could be a scene where he accidentally activates a wrong feature and gets into a bit of trouble.
Maybe Tony scolds Peter for disobeying a safety protocol during a mission. Peter, who looks up to Tony, is deeply hurt by the scolding and starts to cry.
Well, perhaps Peter decides to make his suit because he wants to add some unique features to it. Maybe he's tired of the standard design. He could start by gathering special materials, like some super - durable fabric from a far - off planet. Then, he spends hours in his workshop, carefully stitching and adjusting every detail to make it fit perfectly and also be more functional in his superhero activities.
Well, perhaps in the fanfiction, Tony kidnaps Peter because he believes Peter has some sort of secret that could endanger the world if it gets out. He might be trying to protect the world in his own, extreme way. And Peter is left confused and scared, having to figure out how to convince Tony he's on the right side.
Well, perhaps Tony has some sort of misunderstanding. Maybe he thinks Peter has betrayed him in some way, so he kidnaps Peter. But later, as he realizes his mistake, he tries to make it up to Peter.
Well, one possibility is that Tony could replace Peter in a mission. Maybe Peter gets injured and Tony steps in to finish what Peter started. It could also be about Tony taking over Peter's role in a social or school setting within the fanfiction world.
It could also be that Tony buys Peter some things for his personal life. Such as some nice clothes or tickets to a cool event. This would be a way to show their bond outside of the superhero world. Tony might see Peter as a son - like figure and want to give him experiences that he missed out on in his own youth.
Well, perhaps it could be about Tony and Peter having some sort of adventure where hiccups play a strange role. Maybe they are in a world where hiccups are a sign of a special power, and they have to figure out how to control it while dealing with some sort of villain. It could also involve them learning about the origin of these hiccup - related powers in their universe.
