One interesting fanfiction could be about the surviving heroes trying to reverse the effects of the Snap in creative ways. For example, they might discover an ancient magic that can bring back the vanished ones without the Infinity Stones.
A cool after Infinity War fanfiction might focus on the new relationships that form among the heroes. With so many gone, the ones left have to rely on each other more. They might develop stronger bonds, like a friendship between Rocket and Doctor Strange as they search for a solution together.
There could be a fanfiction where Thanos' motives are explored more deeply. Maybe in this story, he had a change of heart after seeing the chaos he caused and tries to help the remaining heroes put the universe back together. It would be a really different take on his character.
One interesting plot could be that Tony Stark survives the snap and he and Peter Parker have to deal with the post - Infinity War chaos together. They might work on rebuilding the world and in the process, their relationship deepens as they rely on each other more than ever.
One idea could be the remaining Avengers finding a way to reverse the Snap in a completely unexpected way, like traveling to a different dimension where Thanos never got the Stones. Another could be the rise of new heroes among the survivors, who have unique powers that can help in the fight against Thanos' legacy. And perhaps some of the snapped heroes are actually alive in a sort of pocket universe and the Avengers have to figure out how to bring them back from there.
There might be a fanfiction where the Avengers, instead of fighting Thanos in the way we saw in the movie, they actually manage to outwit him before he can even start collecting the Infinity Stones. They form an alliance with some unexpected allies from other galaxies, and together they foil Thanos' plan. This shows a different side of the Avengers' strategic thinking.
One idea could be exploring how the remaining heroes deal with the loss of half the population on a personal level. For example, Iron Man could struggle with survivor's guilt and pour all his energy into finding a way to reverse it. Another could be about the new friendships formed among the survivors as they realize they have to rely on each other more than ever.
One possible fanfiction could be where Tony, after the events of Infinity War, tries to find a way to reverse the snap on his own. He uses his genius intellect to explore different dimensions and discovers a new form of energy that might be the key to bringing everyone back.

One interesting reaction in fanfiction could be the characters dealing with the shock of losing so many comrades. For example, the remaining Avengers might struggle with survivor's guilt. Another could be the exploration of how different characters' powers interact in the face of such a massive threat. Some fanfictions might also focus on the emotional toll on characters like Thor, who has already lost so much and then faces this new catastrophe.
The internal conflicts within the Avengers themselves are quite interesting. Some characters have different views on how to deal with Thanos. For instance, Captain America and Iron Man have their own ideas, which creates tension among the team. This not only adds depth to the characters but also makes the story more complex and engaging.
One idea could be exploring the backstories of the characters in more depth before the events of the trailer. For example, you could write about Thor's journey after losing his eye and how it led him to where he is in the trailer. Another idea is to create a different perspective on the villain, Thanos. Maybe show his internal struggle or his reasons for wanting the Infinity Stones that are a bit more complex than just pure evil. You could also focus on the relationships between the Avengers, like how Iron Man and Captain America might have reconciled off - screen before coming together to face Thanos.
