For Steve and Bucky, if Bucky starts speaking his native language more often in the fanfic, it could strengthen their bond as it harks back to their old days. However, it might also make it harder for new members of the Avengers to fully understand their dynamic. Natasha and Clint might use their respective first languages (Russian and American English) to communicate in a more covert way during missions, which could make their relationship seem more exclusive to the rest of the team.
In a fanfic where Avengers speak their first languages, we could see some great character development. Wanda Maximoff, with her Sokovian background, speaking her native language could bring out her emotions more vividly. It could be used to show her connection to her past and her family. Vision, being created by Stark and others, would likely communicate in English, but perhaps with a more robotic and precise tone. And Hawkeye, as an American, would speak American English. But in a team - up with Black Widow, their language differences could create some interesting moments of miscommunication and then understanding as they work together on a mission.
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.
Thor's relationship with Loki would likely become more complex. He'd be glad his brother is being cared for but also worried about Loki's true intentions. The Avengers, like Tony, might start to see Loki as more than just a villain. They could develop a begrudging respect for his intelligence. For Loki, he might start to feel a sense of belonging, which is something he's never really had. This could soften his attitude towards the Avengers.
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.
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.
With the Avengers finding out Steve is gay, his relationships would evolve. For instance, Sam Wilson would be extremely supportive. He and Steve already have a great friendship, and this would only add another layer to it. Steve's relationship with Bruce Banner might also change. Bruce, who often feels like an outcast himself, could relate to Steve on a different level. They might have more in - depth conversations about acceptance and self - identity. And Steve's connection with Rhodey could strengthen as Rhodey is a man of honor and would respect Steve no matter what. Overall, Steve's relationships with the Avengers would become more multifaceted and based on a deeper understanding of one another.
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.
They might become closer as they share a laugh over the fanfiction. Tony could be more open about his feelings after seeing how fans view him in the Iron Man 3 story.
