They then get involved in some sort of mystery that is related to the aftermath of Infinity War and end up helping the remaining Avengers in an unexpected way.
A plot might also revolve around the villains. Some villains might see the chaos as an opportunity to take over. The Avengers would then have to deal with new threats while still recovering from the events of Infinity War. The fanfic could show how they come up with new strategies and alliances to face these challenges.
