One interesting 'mcu snap crossover fanfic' could be one where characters from different MCU phases interact post - Snap in unexpected ways. For example, a fanfic where Doctor Strange teams up with the Guardians of the Galaxy to reverse the Snap's effects in a dimension - hopping adventure.
A really cool 'mcu snap crossover fanfic' could involve the Snap creating alternate timelines. So, we might see Captain America from an earlier timeline having to team up with the post - Snap heroes like Captain Marvel. They would have to figure out how to merge the timelines and undo the Snap, all while dealing with their different ideologies and experiences from their respective timelines.
When writing an 'mcu snap crossover fanfic', consider the rules of the MCU universe but also feel free to bend them a bit for the sake of your story. Research is key. Look at how different characters' powers work and how they might interact in a post - Snap world. You can start by writing a short scene where two characters meet after the Snap, like Spider - Man meeting Doctor Strange. Build from there, adding more characters and plotlines as you go. Write in a way that shows the readers the impact of the Snap on the MCU and how your crossover is going to change things, whether it's on a small scale for a group of characters or on a large scale for the entire universe.
One idea could be that a Sith Lord somehow gets transported to the MCU universe and tries to take over Hydra. They could use their dark side powers to manipulate the already corrupt organization. Another could be a story where a young Jedi in training from the Star Wars universe ends up in the MCU and teams up with the Avengers to fight a Sith who has also made their way there. Maybe they have to combine the Force with the superpowers of the Avengers to defeat the Sith.
Maybe the Flash could visit the MCU. He could race against Quicksilver. It would be a really cool showdown of speedsters from different universes. And then the Flash could get involved in an MCU - level threat, like Thanos' invasion but in a different timeline. He could use his speed to try and steal the Infinity Gauntlet from Thanos, creating a whole new plotline for a fanfiction.
In a MCU Monsterverse crossover fanfiction, perhaps the Infinity Stones could be involved. Let's say the Time Stone gets lost and ends up in the Monsterverse. Doctor Strange and some of the other Avengers follow it. There they find that the Titans are somehow connected to the power of the Infinity Stones. They need to work with the Titans to retrieve the Time Stone. Godzilla, being a powerful force of nature, could be the key to accessing the area where the Time Stone is hidden.
A great plot could involve Spider - Man from the MCU getting lost in the DCAU and teaming up with the Teen Titans. He could teach them some of his acrobatic fighting moves while they could introduce him to some of their more out - there villains. This would be a fun way to combine the more light - hearted Teen Titans with the street - level heroics of Spider - Man.
Well, in winx mcu crossover fanfiction, a cool idea is the fusion of magic and superpowers. The Winx's magical transformations could be compared to the Hulk's transformation, in terms of a physical and power - based change. Also, the idea of the Winx attending a school like the Xavier Institute in the MCU could be really fun. They could learn about both their magic and how to coexist with mutants and superheroes.
A popular one is 'Heroes United'. It's a more light - hearted take on the crossover. Flash and Quicksilver have a friendly race that turns into a mission to stop a time - traveling villain. It's full of humor and great action sequences that show off the speedsters' abilities.
One interesting concept could be the magic of Harry Potter's world interacting with the high - tech gadgets of the MCU. For example, imagine Hermione trying to figure out how Tony Stark's arc reactor works using magic. Or perhaps the Avengers having to deal with a Dementor attack. Another concept might be characters from each universe teaming up. Harry, Ron and Hermione joining forces with the Avengers to fight a common enemy like Thanos who has somehow harnessed magic as well.
An interesting MCU OC fanfic idea could be an OC who is a journalist. They are always on the hunt for the next big story about the superheroes. This could lead them into all sorts of dangerous situations as they try to get exclusive interviews or expose secrets. Another could be an OC who is a mutant in the MCU (even though mutants are not as prominent yet). This OC would have to deal with being different and feared, while also trying to use their powers for good. And a third idea is an OC who is a reformed villain. They were once on the wrong side but now want to make amends and help the heroes in their fight.
Thor and Godzilla would be an interesting pair. Thor, with his god - like powers and his hammer Mjolnir, could potentially have a showdown with Godzilla. It would be a clash of different kinds of power - Thor's lightning and brute strength against Godzilla's atomic breath and massive size.
