A really cool fanfiction could be about the Avengers watching Endgame and then realizing that the movie is some sort of prophecy or warning. They then start to take steps in their world to prevent similar tragedies from happening again, leading to a whole new set of adventures and challenges.
There might be a fanfiction where the Avengers watch Endgame, but in an alternate universe. In this version, some of the characters who died in the original movie are alive. Their reactions to seeing their potential fates are a mix of shock, determination to change things, and a newfound appreciation for life.
One interesting story could be where they watch it together in the rebuilt Avengers compound. They make comments and jokes throughout, like Tony Stark making snarky remarks about his own character's actions. It adds a humorous and self - reflective touch to the viewing experience.
One tip is to have a good understanding of the original Avengers Endgame movie first. This way, you can better appreciate the fanfiction that might be based on specific plot points, character arcs, or relationships from the movie. Another tip is to explore different platforms where fanfiction is hosted, like Archive of Our Own or FanFiction.net. They have a wide variety of works with different ratings and themes.
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.
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.
In some 'Avengers Endgame Fix It Fanfiction', there might be a concept of time travel without the glitches that occurred in the movie. Maybe they could have a more stable time - travel device which allows them to not only reverse the snap but also fix other events that led to Thanos' victory. This could involve changing things like Loki's escape with the Tesseract in a more beneficial way for the Avengers.
A post - Avengers Endgame fanfiction could center around the psychological impact on the survivors. Like Natasha's death still haunts the team. How does Steve Rogers' decision to go back in time and live his life with Peggy affect the others? It could also be about the search for new Infinity Stones. What if there are more Stones out there? And another idea is to write about the Avengers mentoring a new team of young heroes, passing on their skills and knowledge in a post - Endgame setting.
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.
In a rewrite fanfiction, perhaps Loki could have faked his death all along. He could then return during the events of Endgame, bringing with him an army of Asgardians he had secretly been gathering. His cunning and strategic mind could add a whole new layer to the battle plans against Thanos and his forces.
One popular type of fanfic might be where the Avengers are in the compound and they all gather to watch the Endgame trailer. They could have various reactions. For example, Tony Stark might make some sarcastic comments about how they made the trailer look so epic. Steve Rogers could be more solemn, thinking about the implications of what's shown in the trailer for their upcoming battle. And Thor might be a bit confused at first, but then get fired up as he realizes the importance of what they're about to do.
Some 'Avengers Watch Endgame' fanfictions focus on the reactions of the Avengers during the viewing. For example, Thor might have a more emotional breakdown seeing his past self struggle so much, or Tony Stark could be making sarcastic comments throughout the viewing, which both add humor and depth to the story.
There could be a fanfiction where the Avengers are forced to watch Loki's fan - created adventures in an alternate universe. In this, Loki might be a hero instead of a villain, and the Avengers have to come to terms with this new version of him. They may start to question their own perceptions of good and evil.
