Flash would likely make a lot of jokes. He might say something like 'Hey, that Iron Man guy is like a high - tech version of Batman, but with a much bigger ego!' and make everyone laugh. Superman would try to keep the peace and encourage everyone to look at the positive aspects of the fanfiction. He'd say something like 'Even though it's different, we can learn a lot from their stories.'
Wonder Woman might share her thoughts on the female characters in the Avengers. She could say 'I admire how Black Widow uses her skills, but I also think she could use some more moral guidance like we have in the Justice League.' Aquaman might be a bit dismissive at first, but as the others discuss, he'd start to see the interesting parts of the fanfiction and contribute his own insights, like how the Avengers' underwater adventures compare to his own experiences in the ocean.
Batman would probably be the one to start a serious discussion. He'd point out the differences in the Avengers' operating style compared to the Justice League.
Yang and Ruby would likely have the most animated reactions. They'd be bouncing ideas off each other and getting really excited about certain parts of the fanfiction. Weiss would try to keep the conversation on a more intellectual level, perhaps discussing the writing style or the plausibility of the plot. Blake would be more in the background, but when she spoke, it would be something really thought - provoking, making the others stop and consider her point. The team would have a mix of reactions that would lead to some interesting discussions among them.
During the viewing, Natasha might be the one to start discussions about the fanfiction's plot and how it relates to the real Spider - Man. Tony would jump in with his own ideas and interpretations, often disagreeing with the others just for the fun of it. Thor would be constantly asking questions, like why Spider - Man doesn't have more god - like powers in the fanfiction. Steve would be listening attentively and chiming in when he thinks the story goes too far from the values he believes in. Clint would be using the opportunity to relax and just enjoy the chaos of the Avengers' reactions.
Sasuke's interaction with the Justice League would be complex. He might start off aloof, especially with the more 'cheerful' members like Flash. But he would be drawn to Wonder Woman's warrior spirit. They could have some interesting conversations about honor and combat. Aquaman, with his connection to the sea, might be a bit of an enigma to Sasuke at first. Overall, Sasuke would be constantly evaluating how these new allies or potential rivals fit into his view of the world.
When watching the WandaVision trailer in a fanfiction, the Avengers' interactions would be diverse. Bruce would be nervously fidgeting, and Clint would notice and give him a reassuring pat. Rhodey would be sharing his military - based insights with Tony, who would then counter with his more tech - savvy ideas. Steve would be trying to keep the peace and focus on the important aspects of the trailer, while Natasha would be dropping hints about her own theories, which would draw everyone's attention. Vision, if present, would be providing his unique perspective, which would make the others think deeper about what they're seeing.
They would probably have a lot of banter. Tony would be making snarky comments about his own actions in the movie, and Steve would roll his eyes at some of his more egotistical moments. Thor might be sharing his thoughts on the magic - like technology, which would be really interesting. Natasha and Clint would be sharing knowing looks during the more intense scenes.
During the movie, the Avengers' interactions could vary greatly. Thor might be munching on some popcorn and shouting encouragements to the heroes on screen. Wanda Maximoff could be relating to some of the characters' struggles with power and control. Vision, if he were there, would be processing everything very analytically and sharing his thoughts in a calm and collected manner. Rhodey would be making military - style observations about the battles and tactics. And the Hulk could be getting a bit excited during the action scenes, maybe even making some booming comments that shake the room a bit.
Batman would likely be very cautious around the Avengers at first. He'd be observing their tactics and technology. Thor, on the other hand, might be curious about the Justice League's powers, especially Superman's strength. He might challenge Superman to a friendly test of strength.
They might be confused at first. Since the Avengers are from a different universe in terms of the storylines. They could be intrigued by the different power combinations and relationships presented in the fanfiction.
The interactions would be complex. The Guardians are more of a ragtag group compared to the Avengers and Justice League. Star - Lord might try to charm Lois Lane, which could annoy Superman. Thor could have a friendly competition with Shazam over who has the better lightning - based powers. And Hawkeye could be in awe of Green Arrow's archery skills and ask for some tips.
When it comes to Flash, Ghost Rider's ability to ride his flaming motorcycle could be an interesting contrast. Flash could use his super - speed to lead enemies into Ghost Rider's path, where Ghost Rider could then use his hellfire and chains to subdue them. And in terms of Wonder Woman, her magic lasso and Ghost Rider's powers related to the supernatural could have some sort of synergy, like when dealing with magically - enhanced foes.
