Teamwork is also a very common theme. In these crossovers, the characters have to learn to work together quickly. They come from different backgrounds and have different ways of doing things. In a 'Avenger crossover fanfic' where they cross with the Guardians of the Galaxy, the Avengers' more structured approach has to mesh with the Guardians' more free - wheeling style. This theme of finding common ground and working towards a common goal is often explored in great detail. It usually involves a lot of character development as they overcome their initial differences and start to trust and rely on each other.
One great Avenger crossover fanfiction is 'Avengers and the Justice League'. It's really exciting as it imagines what would happen if the Avengers from the Marvel universe met the powerful heroes of the DC Justice League. The story is filled with epic battles and interesting character interactions, like Iron Man and Batman sizing each other up, and Thor and Superman having a friendly competition of strength.
A popular 'Avenger crossover fanfic' is the one that has the Avengers cross paths with the Fantastic Four. The scientific minds of the Fantastic Four and the combat skills of the Avengers blend well in this fanfic. There are cool battles and strategic planning as they deal with a new threat that requires both their unique abilities.
It could be Captain America. He has a strong sense of justice and kindness. So, if he found a dog, he would surely take it under his wing and protect it. Maybe he'd even train the dog to be a mascot for the Avengers.
Percy could also be a big fan of Hulk. Just like Percy has his own 'inner beast' that he sometimes has to control (his demigod powers), Hulk has his own anger issues. Percy might see a bit of himself in Hulk and also be in awe of Hulk's raw strength. He would probably be interested in seeing if there's a way to help Hulk better control his rage, using his own experiences of self - control.
The fanfic 'Avengers meets the Fantastic Four' is also good. It plays on the similarities and differences between the two groups. The scientific genius of Reed Richards in the Fantastic Four is contrasted with Tony Stark's in the Avengers. And there are some hilarious exchanges between the more humorous characters like the Thing and Hulk. They also team up to face a threat that neither group could handle alone.
One idea could be to cross the Avengers with the characters from Harry Potter. Imagine Iron Man trying to figure out how to use a magic wand, or Thor comparing his hammer to a magic broomstick. Another idea is to crossover with the Star Wars universe. Captain America leading the Rebel Alliance against the Empire would be really cool.
Unique features include combining different fictional universes. For example, in some, characters from other superhero franchises enter the Avenger Civil War plot, creating new alliances and rivalries.
To start an 'Avenger Crossover Fanfiction', begin by brainstorming the plot. Decide if it's going to be a full - on team - up or more of a conflict between the two universes. If you're crossing with the Power Rangers, think about how the Avengers would react to the Rangers' colorful and energetic fighting style. Also, create a character - driven plot. Maybe one of the Avengers has a personal connection to a character in the other universe that drives the story forward. This could lead to some interesting character development and relationships.
One great 'Avenger fanfic' could be the one where Spider - Man has to team up with Doctor Strange to defeat a new magical villain in New York. It's exciting as it shows Spider - Man's quick - wittedness against Strange's powerful magic.
