If Peter was adopted by the Avengers, his relationship with Wanda Maximoff could be quite special. Wanda could help Peter understand and control his emotions better, especially when he's under stress during battles. Peter could also befriend Vision, and together they could explore the boundaries of science and magic. The Avengers would start to see Peter as a full - fledged member of the family. They would be more protective of him, and Peter would feel a stronger sense of belonging. His relationships would no longer be just about superhero partnerships but would be about real family connections. For example, they would celebrate holidays together and have family - style dinners, which would strengthen their bonds even more.
They could become closer. Sharing a laugh over some of the wilder fanfiction plots would create a new bond. For example, if there was a really out - there story about Hawkeye and Black Widow having secret superpowers, they could joke about it together.
Some relationships might become stronger. If they read fanfiction that shows deep friendships between them, they could be more aware of their bond. For example, if there are stories about Iron Man and Captain America's friendship overcoming differences, they might be more likely to work together better.
The living situation could also create some new tensions. Clint might get annoyed with Thor's loud and boisterous behavior. But at the same time, they could also learn to understand and respect each other better. Maybe Clint would start to appreciate Thor's warrior spirit, and Thor would see Clint's skills in a new light. Natasha, being the observant one, would probably play a role in smoothing out any rough patches in the relationships among the team members.
Peter would likely have a closer relationship with the Avengers. He'd be like a little brother to some of them. For example, Thor might take him under his wing and teach him about Asgardian lore. And Captain America would be a great role model for Peter in terms of leadership and moral values.
With Natasha, she might become more protective of Steve. In his de - aged state, she could see him as someone who needs more safeguarding, and their friendship could deepen as she shares her own experiences to help him adapt.
Percy's relationship with the Avengers would be complex. He comes from a different world, the world of demigods. With Tony Stark, there could be some friction at first as Stark is all about technology and Percy is more about his natural powers. But eventually, they would learn from each other. With Natasha, he would develop a deep friendship as she helps him understand the human side of being a hero. Thor would be like an older brother figure, guiding him in the ways of the gods. And Bruce Banner would be someone he could confide in about the difficulties of having powers that are not always easy to control.
It might not change much for some. For example, Bruce would probably still see Bucky as the same person he knows. But for others, like Sam, if he reads some fanfiction where Bucky is painted in a bad light, he might be more on guard around Bucky at first, until he realizes it's just fictional nonsense.
If the Avengers adopted Harry Potter, their lifestyle would transform in numerous ways. Firstly, their communication methods could change. Harry might introduce them to magical ways of sending messages like the Patronus message. In terms of daily activities, they would need to factor in Harry's need to study magic. So, they might set up a special area for him to practice spells and study his textbooks. Their mission planning would also be different. Harry's knowledge of different kinds of magic could provide new strategies for taking on enemies. For instance, he could use the Invisibility Spell to gather intelligence or use magical traps to capture villains. And the Avengers would have to learn about the wizarding laws and customs to ensure Harry doesn't get into trouble with his own world while living with them.
In an alternate timeline, Steve Rogers and Tony Stark might be closer friends from the start. Maybe they met during a different event and bonded over a shared love for some old - fashioned values. Their relationship could be less strained, which would also affect how the Avengers as a whole operate. Without their initial bickering, the team could be more united earlier on.
If they watched 'Iron Man 1' in a fanfiction, their relationships could shift. Tony's early struggles shown in the movie could make the others more protective of him. Thor might offer his friendship more openly. Natasha could start to trust Tony more, as she sees how he overcame difficult situations in the movie. And Clint might stop making some of the sarcastic comments he usually makes towards Tony.
