Some of them could be in denial at first. They might think it was some sort of trick or false vision. But as they watched more and more of Infinity War, they'd have to accept the reality. Then, they'd start to think about how to use this knowledge. Maybe they'd try to find a way to go back in time like Dr. Strange did in the real movie, or find a weakness in Thanos that they didn't notice before.
They might be shocked. Some Avengers could be amused to see different takes on their Infinity War experiences. For example, Thor might be surprised to see how fanfiction writers portray his journey to get Stormbreaker. Others like Iron Man could be either irritated or impressed by the creativity in how his character is used in these fictional stories.
Well, they might be shocked and full of regret. They would see all the mistakes that led to Thanos' victory in Infinity War. Maybe they'd start arguing about who was responsible for what went wrong, like Stark might blame Steve for not being there with them earlier, and Steve would counter about Stark's overconfidence with the whole Ultron situation which might have weakened their position against Thanos in the first place.
They would be shocked. The trailer might show new and powerful enemies that they haven't faced before. For example, Thanos looks really menacing. Some of them would be excited to see their new powers or weapons on display. Captain America might be thinking about how to lead the team better against these threats. And Black Widow would be sizing up the potential new allies or enemies in the trailer.
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.
The Avengers would likely have mixed reactions. Captain America might be very protective, seeing it as his duty to safeguard Black Widow and her unborn child. Tony Stark, on the other hand, might initially be more concerned about how this would affect their battle strategies.
Well, Tony Stark would probably be making sarcastic comments throughout the reading. He might say something like 'This is quite the creative take, but really, do they think I'd act that way?' Steve Rogers would be more serious, perhaps thinking about how the fanfic version compares to the real events. And Thor? He'd probably be a bit confused at first and then start laughing at some of the more outlandish parts.
Well, Naruto characters have unique abilities. For example, Naruto's shadow clones could be used for various strategies. Sasuke's Sharingan could detect hidden threats. They could join the Avengers to fight against Thanos. Maybe Naruto's Rasengan combined with Iron Man's repulsor technology could create a super - powerful attack.
They would be amazed. The Justice League is used to their own brand of super - powered battles, but Infinity War would show them a whole new level of cosmic warfare. Superman might be the first to jump into action, mentally preparing himself to take on Thanos if he was in that universe.
Tony would roll his eyes and say 'This is just someone's wild imagination gone too far'. Steve would read it carefully and think about the moral implications of the different scenarios in the fanfic. Thor would laugh out loud at some of the over - the - top parts.
One possible plot could be the Avengers watching the events unfold in Infinity War and constantly making comments about their own actions. For example, Thor might be yelling at his past self for not going for the head when he had the chance against Thanos. They could also be strategizing on how they could have changed the outcome, leading to some interesting in - group debates and revelations about their relationships with each other.
