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.
By focusing on the key moments from the trailer. For instance, if the trailer showed a powerful new weapon, the fanfiction might have characters speculating about its power and how it will be used in the movie. It could also show characters' reactions to the new looks of the heroes, like Thor's new physique, which was quite different in Endgame.
Another fanfiction idea could be a prequel to her role in Avengers: Endgame. It could show what she was doing in the cosmos just before she received the call to return to Earth. Maybe she was facing a different threat that was related to Thanos in some way, and this backstory could add more depth to her character in the movie.
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.
In Endgame, the Avengers try to reverse the Snap. They come up with a time - heist plan to get the Infinity Stones from different points in the past. There are many emotional reunions and sacrifices. In the end, they are able to bring back those who were snapped, and Iron Man sacrifices himself to defeat Thanos once and for all.
Avengers: Endgame's backstory encompasses a lot. It ties together the loose ends from previous installments, showing how the heroes were affected by past battles and how they prepared for the ultimate showdown with Thanos.
Sure is. The movie draws inspiration and elements from the rich world of Marvel Comics, specifically those related to the Avengers and their adventures.
