One common theme is the clash of art styles. Since Cuphead has its distinct 1930s - style animation look, when it crosses over with other franchises like modern - day 'Adventure Time' or 'My Little Pony', the contrast in art and design becomes a central focus. Another theme is the adaptation of gameplay elements. For example, in a crossover with 'Mega Man', the platforming and shooting mechanics from both universes are combined in new and interesting ways.
One idea could be a Cuphead crossover with Super Mario. Cuphead and Mugman could find themselves in the Mushroom Kingdom, facing off against Bowser's minions alongside Mario and Luigi. They could use their unique shooting skills to help in battles.
Sure. One popular Cuphead crossover fanfiction is the one where Cuphead and Mugman cross over into the world of 'The Nightmare Before Christmas'. It's really interesting to see how their cartoonish styles blend with the spooky yet festive world of Jack Skellington. Another one is the crossover with 'Super Mario Bros.', imagining Cuphead and Mario having an adventure together, perhaps in a casino - like level full of Cuphead - style challenges.
One idea could be that the characters from Cuphead end up in the world of Batim. Cuphead and Mugman might be mistaken for new ink creations in the studio. They could then have to deal with the strange and often menacing creatures in the Batim world while trying to find a way back to their own.
Maybe in the fanfiction, there's a powerful villain who has stolen an important item from both Bendy's world and Cuphead's world. Bendy and Cuphead meet by chance and realize they have a common enemy. They start their journey together. Cuphead teaches Bendy some of his acrobatic moves, and Bendy shows Cuphead how to use the environment to his advantage with his ink.
Think about the characters' personalities and how they will interact. In a crossover with the Looney Tunes, Bugs Bunny's slyness would contrast with Cuphead's more naïve and adventurous nature. Develop their dialogue and actions based on this. Start with a strong opening that grabs the reader's attention, like Cuphead suddenly finding himself in the middle of a Looney Tunes cartoon chase.
The art styles could be combined by having the characters keep their distinct looks but interact with environments that blend both styles. For example, Cuphead and Mugman could be running through a hall in the Batim studio that has the dark, inky look of Batim but with Cuphead - style geometric patterns on the walls.
The Devil from Cuphead could be really interesting. Imagine him showing up in Bendy's world. His menacing presence and powers would be a huge threat. Bendy and his friends would have to figure out how to deal with this new and powerful foe. And the Devil could also be interested in Bendy's world for some dark purpose, like trying to corrupt it further.
A crossover between Cuphead and Pulp Fiction would be really wild. Imagine Cuphead characters in the seedy underworld of Pulp Fiction. The cute Cuphead and Mugman might be completely out of place but in an interesting way. They could interact with the tough guys like Vincent and Jules. Maybe they would be on a mission to get back some special item from the bad guys in the Pulp Fiction world, and their cartoony abilities would be put to the test in this much more adult - themed and dangerous setting.
It can make the game seem darker. Since the fanfiction involves abuse, it might change how fans view the otherwise relatively light - hearted Cuphead game. They may start to look for hidden signs of potential abuse or darker undertones in the game's story and characters.
