Well, characters like Dr. Strange might be a bit critical. He'd notice the inaccuracies in the use of magic in some fanfictions. However, he might also appreciate the efforts of fans to incorporate his character into different and exciting scenarios. The more down - to - earth characters like Falcon might be more accepting and just enjoy seeing their world expanded in new and different ways through the fanfiction.
Characters' responses could be mixed. Scarlet Witch could be intrigued by how fans explore her powers and her emotional state in fanfiction. She might see it as a way to understand how she's perceived by the public. War Machine, on the other hand, might be a bit dismissive at first, but as he reads more, he could start to see the charm in the fan - created stories about the Avengers.
Some characters would likely be entertained. For instance, Loki might enjoy seeing the various ways fans write him as a more complex anti - hero. He'd probably find the creativity in the fanfiction quite appealing.
They react differently. Stark might immediately start thinking about how to improve the tech in the movies. Cap is likely to be more focused on the story and the characters' motives.
Some would be intrigued. Captain America, being an open - minded person, might be interested in seeing different interpretations of their team dynamics. He could even gain new insights about his relationships with his fellow Avengers through the fanfiction.
The Avengers would likely have a range of reactions. Captain America would respect the Incredibles' sense of justice. And the Hulk might just be confused at first but then find it cool.
Tony Stark might use his quick wit and technology. He could immediately scan Peter to make sure there's no physical danger causing the hyperventilation. Then he'd probably crack a joke to try and calm Peter down, like 'Kid, you breathe any faster and you'll fly away like a human jetpack.'
The characters might also get confused. Fanfictions often have their own unique plotlines that can be quite different from the official story. So when they see these strange twists and turns, like Thanos suddenly becoming good in the fanfiction, they'd be scratching their heads and trying to figure out what's going on.
Some of them might be shocked. Tony Stark, for instance, might immediately start thinking of ways to use technology to change what he saw. Steve Rogers would probably be more concerned about the moral implications of interfering with the future.
They might be confused at first. Fanfiction can be wild and different from their real experiences.
Thor could be angry. He's a proud warrior and being kicked out like that might be seen as an insult. He might even challenge Tony in some way, either verbally or physically. However, he also has a sense of honor and might listen to Tony's reasons if given the chance.
The Avengers' reactions can vary greatly. Some might be intrigued, while others might find it odd or amusing.
They would probably be very surprised. Some might laugh at the creative ideas in the fanfiction.
