What are some interesting ideas in 'Avengers Endgame Alternate Ending Fanfiction'?

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.

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.

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.

Well, in the original ending, Iron Man snaps his fingers to defeat Thanos and his army. But in the fanfiction, it could be someone else doing it. For example, Hulk could have found a different way to use the Infinity Stones that didn't require self - sacrifice.

One idea could be a crossover with the Doctor Who universe. The Avengers could team up with the Doctor to fight a common enemy that threatens both their universes. Maybe Thanos somehow gets access to Time Lord technology and the combined forces have to figure out how to stop him from using it to rewrite all of reality.

Imagine a fanfiction where Captain Marvel uses her energy - based powers in a completely new way during the final battle in Avengers: Endgame. Instead of just punching and flying around, she could manipulate the energy fields in a way that disrupts Thanos's entire army. This would be a creative take on her character and her abilities.

Perhaps a fanfiction where the Infinity Stones in the Endgame have an unexpected effect on certain anime characters. These characters start to develop new abilities or forms that are a blend of their anime selves and the power of the Stones. This could lead to a whole new dynamic in the fight against Thanos, as the Avengers have to figure out how to work with these newly - empowered anime allies.

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.

One interesting plot idea could be that in the alternate timeline, Tony Stark never becomes Iron Man. Instead, he devotes his life to clean energy research and Pepper Potts takes on a more superhero - like role, using Stark tech to fight crime. Another idea is that the Avengers lose the Battle of New York in this timeline, which leads to a dystopian world where the Chitauri rule, and the remaining heroes have to form an underground resistance.
