One idea could be an OC who has the power to time - travel in a unique way, not like the Avengers' method. They could accidentally disrupt the events of 'Endgame' further while trying to help. For example, they might create alternate timelines where different villains gain power. Another plot could involve an OC who is a long - lost relative of one of the Avengers. They show up during the final battle and use their hidden powers to turn the tide. And a third idea is an OC who is from a different dimension entirely and has knowledge of how to defeat Thanos more easily, but they have to convince the Avengers to trust them first.
To create a believable character for 'Avengers Endgame' OC fanfiction, first, give them a clear backstory. For example, if they have powers, explain how they got them. Were they born with it, or was it the result of an experiment? Second, give them flaws. A character without flaws is not believable. Maybe they're too impulsive or have a fear that holds them back. Third, give them relationships. They could be friends with some of the minor characters in the 'Avengers' universe. This will help them fit into the world of '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.
