Well, in some fanfictions, there's a scene where Peter gets injured during a battle. The Avengers then all rally around him to take care of him. Thor might use his powers to heal him a little, and Natasha would stay by his side, talking to him to keep him calm. This shows their love and care for Peter as if he was their own. Also, when Peter first moves into the Avengers compound, they all help him decorate his room. Each Avenger adds a personal touch, making it a really cozy and special place for Peter.
One heartwarming scene could be when the Avengers teach Peter how to use his powers more effectively. Tony Stark might be showing him new gadgets while Steve Rogers gives him advice on leadership. Another scene could be the Avengers celebrating Peter's birthday together. They could throw a big party at the Avengers compound with lots of presents and cake. It would show how they've become like a family to him.
A great heartwarming scene could be the Avengers taking Peter on a camping trip. They set up tents, cook over a campfire, and tell stories. Clint Barton could teach Peter how to shoot arrows, and Bruce Banner would share his knowledge about science in a more laid - back outdoor setting. Peter would feel like he truly belongs with them, and it would be a moment of bonding that's really sweet in the context of the fanfiction.
In some fanfictions, a really touching scene is when Peter Parker's kid gets into trouble at school. Instead of scolding, he sits down with the kid and talks about how to handle bullies, using his own experiences as a bullied kid. He gives his child the confidence to stand up for themselves in a positive way. This shows his growth from his own past traumas to being a great dad.
Perhaps Peter is feeling a bit homesick. The Avengers, noticing this, decide to recreate a part of Queens in the Avengers compound. They set up a small street fair with all the food and games that Peter loves from his neighborhood. Tony Stark even manages to get his hands on some of the best New York - style pizza. Peter is overjoyed and feels a strong sense of family among the Avengers.
In the fanfiction, Peter's character development is quite remarkable. Initially, he's a bit naive and inexperienced in the world of the Avengers. But as time goes on, he picks up on their combat strategies. He becomes more strategic in battles, not just relying on his spidey - sense. Socially, he grows too. He learns to communicate better with the other Avengers, understanding their different backgrounds. He also starts to mentor new, younger heroes, showing how far he's come from being the new kid on the block.
One heartwarming scene could be when Natasha first takes Peter in. She might show him his new room, filled with things she carefully picked out for him, like a warm comforter and posters of his favorite things. Another could be when Peter has a bad day at school, and Natasha bakes his favorite cookies and they sit and talk about it. Also, when Peter has a big accomplishment, like winning a science fair, Natasha is there beaming with pride and giving him a big hug.
One possible plotline could be the two Peters from different universes teaming up to fight a new threat that the Avengers can't handle alone. Maybe they use their combined spider - powers in unique ways.
One interesting story could be about Peter's first mission with the Avengers. He's nervous but tries to prove himself. Another might focus on Peter's relationship with Tony Stark within the Avengers, like how Tony mentors him. There could also be a fanfiction where Peter discovers a new power during an Avengers adventure and has to learn to control it quickly.
There are also fanfictions where the Avengers watch scenes from a parallel dimension where they have different powers or team dynamics. This can lead to a lot of character development as they compare and contrast themselves with their counterparts. They might learn new ways of using their powers or new ways of interacting with each other from what they see in those scenes.
One heartwarming toddler Peter Parker fanfiction could be about him using his newfound powers in innocent ways at a very young age. For example, he might use his super strength to help his aunt May carry heavy groceries without her even realizing it was him. Another could be him befriending a little lost animal in the park and using his spider - sense to find its owner. And there could be a story where he tries to make his neighborhood a better place by cleaning up the local playground all by himself, with his tiny hands and determination.
Peter would likely feel betrayed. He looks up to the Avengers, and for them to hurt him would shatter his trust. He might start to question his own judgment in idolizing them and could become more withdrawn.
Maybe when they have their first dinner party as a married couple. Tamaki is being the perfect host, and Haruhi is by his side, making sure everything runs smoothly. Their friends see how well they complement each other and it's just a really sweet moment.
