Peter could be a character with some heroic or special qualities. He might be a young man with a big heart. Morgan could be a young girl, perhaps a student at the school. They could have a special bond, like an older brother - like figure (Peter) and a younger sister - like figure (Morgan).
Well, it could be that Peter picks Morgan up on his skateboard, which Morgan is super excited about. As they travel through the neighborhood, Peter points out different things like a new puppy he saw the other day or a cool treehouse some kids are building. Then, when they get home, they play a fun game together in the yard.
Perhaps it develops as they face challenges together. For example, if some villains target Peter at school, Natasha is there to protect him. This act of protection makes Peter trust her more deeply, and Natasha starts to see Peter as someone she wants to mentor and protect in the long run. They become closer as they rely on each other in difficult situations.
Well, maybe they'll go for ice cream on the way home. Peter could start chatting about his day at school, like how he aced a science test or had an interesting discussion in history class. And Natasha would be all ears, giving him some advice here and there based on her own experiences.
Perhaps when Tony picks up Peter, there's some sort of danger lurking nearby. So they end up having an impromptu adventure on the way back. Tony could show off some new gadgets to Peter to deal with the threat.
One possibility is that they could stop at a diner on the way home. Tony might give Peter some advice about his schoolwork or his superhero training. They could also discuss the latest events in the superhero world.
This simple act of picking Peter up from school can strengthen their bond. It shows that Tony cares about Peter on a personal level, not just as a fellow superhero. Peter would feel special and more connected to Tony.
Their relationship could develop through shared experiences. For example, on the drive home from school, they start to open up more to each other. Tony might share some of his own childhood stories with Peter, which makes Peter feel closer to him.
In the fanfiction, Peter might gain new powers. Since Mjolnir can only be lifted by those worthy, if Peter picks it up, he could have Thor - like abilities. Maybe he'd be able to control lightning and have enhanced strength. He could also use Mjolnir in combat against powerful villains in a really cool way.
In this fanfiction, Peter Parker is the central figure as he's the one who has the extraordinary event of picking up Mjolnir. Thor is bound to be a main character too. His presence could add a lot of depth to the story. Maybe he could be a mentor - like figure to Peter, teaching him about the power of Mjolnir. Then there could be other characters like Aunt May. She might be worried about Peter having this new and extremely powerful object. And villains such as Doctor Octopus or Green Goblin could be main characters as well if they try to get their hands on Mjolnir when they find out Peter has it.
