In a fanfiction based on Avengers Endgame and diapers, there could be a situation where Hulk, who has now merged his personalities more, finds a baby Hulk - like creature. He has to handle the little one, including all the diaper - related tasks. This could be a really funny and heartwarming story. Also, Black Widow could be brought back in a way where she has to take care of a baby that is crucial to the future of the universe. Diapers would be a part of this new adventure for her, as she tries to protect the baby from those who would do it harm.
Diapers can add humor when a big, tough Avenger like Thor is completely clueless about how to put one on a baby. His fumbling attempts and the look of confusion on his face would be really funny. Also, if Hulk accidentally rips a diaper while trying to be gentle with a baby, that would be a humorous moment.
Well, in some Avengers diapers fanfiction, there are storylines centered around time - travel gone wrong. An Avenger could end up in a time where they are a baby again, complete with diapers. This creates a whole new dynamic as the other Avengers have to figure out how to handle this situation. Maybe Iron Man tries to use his technology to age the baby - Avenger back up, but it just causes more problems. Or perhaps Captain America has to use his old - fashioned parenting skills to take care of the diaper - wearing Avenger. It's a really interesting concept that combines the superhero world with the chaos of baby - hood.
Maybe in the fanfiction, the reverse time heist goes wrong in a different way. Instead of getting the stones, they end up changing key events in the past that have unforeseen consequences in the present. For example, they prevent the birth of one of their own members, and then have to figure out how to fix it while still dealing with Thanos. It would be a complex and interesting storyline.
Sure, there are. They expand on the events and characters from the movie, offering additional depth and perspectives.
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.
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.
Maybe Black Panther gets transported to an alternate dimension where the Avengers have different personalities. He has to figure out how to work with them to get back to his own dimension. In this story, we could see how his leadership skills are tested in a very strange situation. It would also be interesting to explore how the other Avengers from the different dimension react to his presence and his unique abilities.

One common theme is self - discovery. Kraglin is often depicted as trying to figure out who he is without Yondu. For example, in many fanfictions, he has to learn new leadership skills or find new friends and allies.
