What are some interesting Captain Marvel crossover fanfiction ideas?

One idea could be a crossover between the X - Men and the Avengers. Imagine Wolverine teaming up with Captain America in a battle against a common enemy like Ultron. Another could be a Spider - Man and Doctor Strange crossover, where Spider - Man's quick thinking and agility combine with Doctor Strange's magic to solve a multiverse - level threat.

One great idea could be a story where Percy Jackson's world is in danger and Captain Marvel is somehow drawn into it. Maybe a powerful ancient Greek monster has powers that start to affect other dimensions, and Captain Marvel comes to help. She could use her super strength and energy blasts to fight alongside Percy and his friends against the monster. Percy, with his control over water, could also be useful in a fight, like creating a giant wave to distract the enemy while Captain Marvel attacks.

One idea could be a time - travel fanfic where Captain Marvel and Captain America team up in a different era. Maybe they end up in the 1920s and have to deal with a Hydra - like threat that's starting to form early. Another could be a fanfic where they swap powers for a day and have to learn to adapt to each other's abilities. For example, Captain America trying to control Captain Marvel's photon blasts and Captain Marvel having to rely on just her combat skills like Cap usually does.

A crossover with Arrow would also be cool. Maybe Captain Cold gets involved in Star City's problems and has to work with Oliver Queen. They could have some great fight scenes together and share their different views on justice.

One idea could be Captain Marvel bringing back some alien tech that the Avengers have to figure out how to use. It could lead to new powers for some of the members or a new way to defend Earth.

Imagine a fanfiction where Captain Marvel uses her energy - based powers in a completely new way during the final battle in Avengers: Endgame. Instead of just punching and flying around, she could manipulate the energy fields in a way that disrupts Thanos's entire army. This would be a creative take on her character and her abilities.

How about a story where the Avengers are pitted against Dio? The Avengers would have to deal with Dio's time - stopping ability with their own powers. Iron Man could try to create a device to counteract Dio's time stop, while Captain America uses his strategic skills to lead the fight against Dio's minions.

One idea could be that Batman finds himself in the Marvel universe due to a strange multiverse rift. He teams up with Iron Man to stop a tech - based villain who is stealing advanced technology from both their worlds. Another could be Batman and Spider - Man working together in Gotham. Spider - Man's acrobatics and sense would be a great addition to Batman's detective skills.

A cool dc marvel crossover fanfiction might involve Batman and Iron Man. Picture Batman being intrigued by Iron Man's high - tech gadgets and the two of them collaborating to create an even more advanced piece of technology to defeat a new breed of super - criminals that are using alien and advanced Earth - based tech.

A great concept for Marvel Avengers crossover fanfiction is to have the Avengers cross paths with the Fantastic Four. The two teams could collaborate on a scientific project that goes awry, creating a new threat that only their combined powers can defeat. Another possibility is a crossover with the Eternals. Since the Eternals have been on Earth for a long time but hidden, their discovery by the Avengers could lead to a complex relationship. They might initially be at odds, but then realize they need to work together to stop a greater evil that is awakening on Earth. Also, an Avengers crossover with Blade would be interesting. Blade could seek the Avengers' help in fighting a new breed of vampires that are more powerful than ever and have ties to some dark magic that the Avengers have to figure out.
