There's 'The Aftermath'. This fan fiction delves deep into the emotional and physical recovery of the characters after the endgame events. It's really detailed, exploring how they cope with the changes and traumas, which makes it stand out among others.
Another way is to join fan communities related to the 'endgame' topic. For example, on Reddit, there are specific sub -reddits where fans discuss and recommend their favorite endgame fan fictions. You can get some really good suggestions from there.
Iron Man is a very popular choice. His sacrifice in the movie was so impactful that many fans like to explore alternate endings where he survives or different scenarios leading up to his death. They might write about his relationship with Pepper Potts in more detail or his interactions with the other Avengers in a different light.
You could also write a fan fiction where the Avengers use time travel in a different way. Instead of going back to collect the Stones, they go back to stop Thanos from ever getting the idea of the Snap. This would involve changing key events in Thanos' past, like preventing him from meeting Gamora or finding out about the Infinity Stones.
In the world of Endgame fanfiction, 'The Guardians' Role' is quite engaging. It gives more depth to the role of the Guardians in the Endgame events. 'Tony Stark's Legacy' is a touching fanfiction that looks at how Tony's sacrifice in Endgame influenced the future. And 'The Avengers Reunited' shows a different scenario of the Avengers coming back together after Endgame, with some unexpected twists and turns.
In my opinion, the best fan fiction is one that stays true to the essence of the original work while still being creative. It should respect the lore and the world - building of the source material. For instance, a Star Wars fan fiction should follow the rules of the Force and the different species and cultures in the galaxy far, far away. Also, fan interaction can play a part. If a fan fic has a community of readers who are excited about it, discuss it, and even contribute ideas, it can enhance its status as a great piece of fan - created work.
One good practice is to find reliable platforms. For example, some well - known fanfiction websites usually have a wide range of works. Another is to read reviews or ratings if available. This can help you avoid poorly written or out - of - character stories. Also, make sure you respect the original source material and the creativity of the fanfiction authors.
One highly regarded story is 'The New Beginning' which explores what happens after the events of Endgame in a really unique way. It delves deep into the characters' emotions and how they cope with the new world they're in. Another great one is 'Beyond the Snap' which focuses on the alternate timelines that could have been created during the events of the movie. It's really interesting to see how the author plays with the concepts from the movie.
One great anime fan fiction is 'A Different Path' which explores an alternate universe for the characters of 'Naruto'. It delves deep into the relationships and how different choices could have led to a whole new set of adventures. Another one is the 'Fullmetal Alchemist' fanfic 'The Brothers' Redemption' that gives a new perspective on the Elric brothers' journey, adding more emotional depth and complex plot twists.
