Tony Stark would probably be flattered that people are so interested in creating stories about his adventures in Iron Man 2. He might even share some of the fanfiction on his social media if he likes it. As for the other Avengers, Steve Rogers might use it as a chance to understand modern pop culture better. He could see it as a window into how the public perceives them. Meanwhile, Thor would be constantly asking questions about the strange elements in the fanfiction, like why Iron Man's suit has some ridiculous new feature that doesn't seem practical at all.
They could be shocked. Some of the scenarios in fanfiction can be extreme. For instance, if it has Iron Man suddenly turning evil, it would be a big surprise to them.
Some of them might be really into it. Like Spider - Man (if he's considered part of the Avengers for this), he's a big fan of Iron Man in the first place, so he'd probably enjoy the fanfiction. He might even get some new ideas for his own tech - related projects from it. Dr. Strange, on the other hand, might be a bit dismissive at first. He's used to dealing with real magic and might not see the point in fictional stories about Iron Man, but then he might start to appreciate the creativity.
When it comes to the Avengers reading Spider - Man fanfiction, Tony would be the first to analyze the technology and innovation aspects. He might even start a discussion with Bruce about how the fan - written science could be improved. Steve would try to find the moral lessons in the stories, if any. Thor would be drawn to the heroic deeds described in the fanfiction, comparing them to his own. Natasha would study the character dynamics, especially those involving Spider - Man and his allies or enemies. Clint would simply enjoy the light - heartedness of it all, laughing at the comical parts and using it as a way to unwind from their usual superhero duties.
They might be quite surprised. Some might find it interesting to see how fans imagine different scenarios for Iron Man 3. For example, Thor could be amused by the creative interpretations of Stark's technology. Captain America might be a bit taken aback by some of the more out - there plot ideas in the fanfiction.
The Avengers' reactions would be diverse. Natasha Romanoff might be interested in the character dynamics shown in the fanfiction. She could analyze how the relationships between the characters are different from what she knows in real life. Bruce Banner would likely be cautious. He might worry that some of the fanfiction could mislead the public about the Hulk's nature. And Clint Barton would probably just laugh it off as a fun, fictional take on their lives, but also be a bit critical if it doesn't stay true to their essence as a team.
Well, Captain America might be a bit shocked at first. He's from a different era and fanfiction's modern concept could be strange to him. Thor would probably find it amusing and might even think it's some sort of Midgardian magic story about his friend Stark. Black Widow would analyze it carefully, looking for any insights it might give into Iron Man's character or the public's perception of him.
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.
Captain America would likely try to be the voice of reason. He'd approach Tony with empathy, trying to understand what's going on in his head and find a way to bring him back to his senses. He might also try to keep the other Avengers calm and focused on helping Tony rather than seeing him as a threat immediately.
Some might be confused. For instance, Hawkeye might not fully understand all the complex multiverse concepts in the fanfiction. But others like Scarlet Witch could find elements that resonate with her own experiences, especially those related to the multiverse. So she might be more empathetic towards the fanfiction.
Some would be curious. Hawkeye might pick up on the unique skills and abilities given to the Team Red characters in the fanfiction and compare them to his own. He could either be inspired or find it a bit far - fetched.
