Well, in some of the fanfictions, there are characters showing shock and disbelief. For example, some characters might be seen crying as they watch the trailer, realizing the enormity of what's to come in Endgame. It really adds an emotional depth to the pre - Endgame scenario.
In the 'Avengers Watch Endgame Trailer Fanfiction', there could be intense discussions among the Avengers. They might be speculating about different strategies based on what they see in the trailer. Like Thor could be thinking about how to better use his new axe after seeing some of the battle scenes in the trailer.
There could also be some analytical reactions. Fans in the fanfiction might be dissecting every frame of the trailer, trying to figure out how the story will unfold. They could be speculating about new suits, new alliances, and what the final battle will look like. They might be discussing whether certain characters will die or not based on the trailer's hints.
One interesting reaction in fanfiction could be the exploration of how different characters coped with the aftermath. For example, a fanfic might show how Hawkeye dealt with the loss of his family in more depth. He could have moments of extreme grief that were not fully shown in the movie, like breaking down alone in the forest.
Captain America could have a more determined look. In fanfiction, he would likely see the trailer as a call to action, a chance to rally the team even more. He'd probably think about how to boost the morale of the Avengers and the rest of the world. His reaction would be about inspiring hope in the face of such a seemingly hopeless preview.
Some might be amazed. For example, Hawkeye would be impressed by Iron Man's new flying maneuvers. Others like Falcon could be taking mental notes on Iron Man's technology for his own gear. And Tony Stark himself would probably be enjoying the attention and bragging a bit about his new suit's features.
The Avengers' reactions to Endgame fanfiction would vary greatly. Natasha Romanoff might be intrigued by the different relationships and storylines presented in the fanfiction. Bruce Banner would probably approach it from a scientific and analytical perspective, trying to understand the logic (or lack thereof) in the fictional scenarios. Clint Barton might be more focused on how his character is depicted, especially in relation to his family.
Captain America is also a key focus. His leadership qualities are highlighted. He could be seen rallying the other Avengers as they watch the trailer, giving inspiring speeches about not giving up and fighting for the universe.
Well, one interesting thing could be the characters' reactions. They might have different emotional responses seeing the events of Endgame unfold in the fanfiction compared to the movie. For example, Iron Man could show more internal struggle as he witnesses his sacrifice again.
A really cool plot idea could be that the Avengers are watching Endgame in a sort of 'alternate reality cinema' where the events in the movie start to bleed into their real world. So they have to stop the movie from fully playing out to prevent chaos in their own universe. This would involve a lot of action and strategic thinking as they try to stop things like Thanos from emerging from the screen while also trying to understand the significance of what they're seeing in the movie.
The Avengers' reactions would vary greatly. Natasha would likely be intrigued by the characterizations in the fanfic. If the writer got her personality right, she'd be impressed. Bruce, on the other hand, might be a bit more analytical. He'd be looking at how the science in the fanfic was portrayed. Clint would probably be more interested in how the relationships between the characters were written, especially those involving his family.
In some fanfictions, the Avengers might watch the deaths in Endgame as a form of training or preparation for future battles. This could lead to them developing new strategies to avoid similar losses. For example, they might focus on improving their teamwork or finding new ways to protect each other. They could also be haunted by the deaths they saw, which could affect their mental state during subsequent missions.
