In a fanfiction where Tony didn't die, he could continue to be a mentor to the new generation of Avengers. He would use his genius intellect to develop even more advanced technology to protect the Earth. Maybe he'd finally have the time to focus on his family life with Pepper and their daughter, while still being involved in superhero affairs on a more strategic level.
If Tony didn't die, the story would be drastically different. For one, the Avengers would still have his leadership and resources. His presence would change the dynamic during the post - Endgame events. They wouldn't be mourning his loss, but instead, be planning new strategies with him at the helm.
Sure does. The death of Iron Man in the Avengers: Endgame comic is a pivotal plot point. It changes the course of the story and leaves a lasting impression on readers.
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.
