One popular idea could be a crossover with 'The Simpsons'. Imagine the Futurama characters visiting Springfield. Another could be a crossover with 'Star Trek', where the Planet Express crew teams up with the Starfleet for some intergalactic adventure. And there might be crossovers with other sci - fi shows like 'Doctor Who', with the Doctor and Fry perhaps sharing some time - traveling experiences.
One idea could be creating an OC who is a brilliant alien scientist from a far - off planet. This OC could come to Earth to study the unique mix of species on the Planet Express crew. Another idea is an OC that is a time - traveling bounty hunter who gets involved in the crew's adventures, causing all sorts of chaos and unexpected twists. Maybe an OC that is a half - human, half - robot who struggles with identity issues, similar to some of the existing characters in Futurama.
One possible plot could be that Naruto and his friends somehow get transported to the Futurama universe. Maybe they're chasing after a rogue ninja who has a device that can open portals to different dimensions. In the Futurama world, they team up with Fry, Bender and the rest. Naruto could teach them some ninja skills, like how to stealthily move around, and in return, the Futurama crew could introduce Naruto to some of their advanced technology, like the Planet Express ship. It would be a really fun mix of the two very different universes.
A cool crossover would be with the One Piece universe. Rin could be on a pirate ship, using his powers during sea battles and exploring the Grand Line. Another idea is a crossover with the My Hero Academia world. He could attend U.A. High and learn about different quirks while also showing off his own unique abilities. A crossover with the Inuyasha world would also be great. He and Inuyasha could team up to fight demons together.
Another popular crossover is with the Pokémon world. Samus exploring the Pokémon regions, perhaps using her skills to help or hinder trainers. She could encounter powerful Pokémon and have to use her own abilities to get out of tricky situations. It's an interesting contrast between her high - tech world and the more natural, creature - based world of Pokémon.
Well, a really interesting madara crossover fanfiction idea could be a crossover with the Bleach universe. Picture Madara in the Soul Society, interacting with the Soul Reapers. He could be mistaken for an extremely powerful Hollow at first, and then the story could unfold as he tries to find his way back to his own world or decides to explore this new realm of existence. It would be full of action and interesting character interactions.
One popular idea could be an Airwolf crossover with another military - themed show. For example, a crossover with 'MacGyver' where MacGyver uses his skills to help fix some high - tech issue on Airwolf. Another could be a crossover with a science - fiction show like 'Stargate SG - 1', where the advanced technology of Airwolf is compared or integrated with the alien tech in Stargate. A third idea might be a crossover with a post - apocalyptic show, and Airwolf is used to patrol and protect the remaining survivors in a desolate world.
One popular idea is an Erza crossover with the Harry Potter universe. Imagine Erza attending Hogwarts and using her combat skills in magical duels. Another is a crossover with the Avatar: The Last Airbender world. Erza could learn bending techniques and fight alongside the Avatar. A third could be a crossover with the Naruto universe, where she might interact with ninja and use her magic in the shinobi world.
One popular idea is a Vergil crossover with Dante from the same Devil May Cry series. It could explore their complex relationship in new scenarios. Another is a crossover with characters from other action - oriented games like Bayonetta. They could team up to fight a common, powerful enemy. Also, a crossover with a character from a fantasy series, such as Geralt from The Witcher, might be interesting. Vergil's skills and personality could create some great interactions with Geralt.
One popular idea is a crossover between 'Naruto' and 'One Piece'. Imagine Naruto characters on a pirate ship or Luffy trying to master chakra. Another is 'Sailor Moon' and 'Cardcaptor Sakura'. The magical girls could team up to fight a common evil. And a 'Fullmetal Alchemist' and 'Attack on Titan' crossover, where the alchemists use their skills to combat the Titans.
Well, an MK crossover with the Witcher could be really cool. Geralt could find himself in the MK world, having to use his monster - hunting skills against the likes of Mileena and Baraka. The Witcher's magic and swordsmanship combined with the brutal and magical world of MK would offer a lot of creative potential for a fanfiction writer.
