This often leads to epic adventures and new alliances. It gives the writers a chance to explore different magical or scientific solutions.
Captain Marvel is also very popular. Since she's so powerful, fanfiction often has her playing a major role in the fight against the remaining threats and in the restoration of the universe.
Definitely Captain America. He's always been a leader and in the aftermath of Infinity War, his leadership would be crucial in keeping the remaining heroes together. Also, Thor, who has lost so much, would be a great focus. His journey of dealing with his losses and finding a new purpose could be really interesting.
One of the most common tropes is the 'fish - out - of - water' story. For example, when a character from Earth is suddenly thrust into the strange and often dangerous world of the Stargate planets. It creates a lot of opportunity for character growth and discovery.
The team - up trope is also quite common. Kratos joining forces with the RWBY team to take on a powerful foe. This allows for interesting battles and strategies as they combine their different fighting styles. Also, the 'lost in a new world' trope is popular. A character from either universe finding themselves alone in the other universe and having to figure out how to survive and get back home.
One great 'After Infinity War' fanfic is 'Surviving the Snap'. It focuses on the remaining heroes trying to pick up the pieces. It has really well - written characters and an engaging plot that keeps you hooked from start to finish.
The trope of alternate universes is also quite popular. In these fanfics, the world of the Stormlight Archive could be completely different. Maybe the Voidbringers are the heroes and the Knights Radiant are the villains. It gives a fresh perspective on the existing characters and the overall lore of the series. It also allows for a great deal of creativity on the part of the fanfic authors.
One popular trope is 'Ahsoka as a Mentor'. In many fanfics, she takes on the role of guiding a young, inexperienced character. It's a great way to show her growth and wisdom.
A common trope in 'Konan Naruto Fanfic' is the 'Power - Up' trope. For example, Konan might gain new abilities or Naruto might learn to use his powers in a new way because of their interaction. There's also the 'Alliance Against a Greater Evil' trope. They join forces to fight a powerful enemy that neither could face alone. And the 'Character Exploration' trope is popular.
