One idea could be a crossover with Resident Evil. The main character from Dead Rising could find themselves in a Resident Evil - like scenario, dealing with different types of zombies and bioterror threats. They could team up with Resident Evil characters like Leon or Claire to fight against a common enemy.
A crossover with The Walking Dead might also be cool. Imagine the more comical and over - the - top elements of Dead Rising mixing with the grittier, survival - based world of The Walking Dead. Characters from Dead Rising could introduce some of their wacky weapons to the survivors in The Walking Dead universe, changing the way they fight the undead.
One idea could be an OC who is a skilled hacker. They use their skills to manipulate the mall's security systems during the zombie outbreak in Dead Rising. This could add an interesting dynamic as they not only have to fight zombies but also deal with the consequences of their hacking, like accidentally releasing more zombies or getting hunted by the military for interfering with their operations.
One idea could be a crossover with the Alien franchise. Picture Isaac Clarke in a derelict Alien ship, facing both Necromorphs and Xenomorphs. The different types of terrifying creatures could create a really intense and unique horror scenario.
You could do a crossover with 'Castlevania'. The gothic horror elements of 'Castlevania' would blend well. Dracula could be a powerful killer, and the heroes from 'Castlevania' could be survivors. The survivors might have new abilities like using holy water or magic spells against the killers. It would also be interesting to see how the 'Dead by Daylight' maps would be transformed with the addition of 'Castlevania' - like architecture and elements.
One idea could be a story where characters from 'Dead or Alive' cross over into a post - apocalyptic world. They could use their fighting skills to survive against new and dangerous enemies. Another idea is a crossover with a fantasy realm, and the 'Dead or Alive' characters have to adapt to magic and mythical creatures. For example, Kasumi might learn to use magic spells while still relying on her ninja skills.
A cool 'Walking Dead Crossover Fanfiction' idea is to cross it with 'The X - Files'. Mulder and Scully could be investigating the zombie outbreak. They might find out that it's not just a normal virus but some kind of government experiment gone wrong, which ties in with the conspiracy theories they usually deal with. And the characters from 'The Walking Dead' would be skeptical at first but then realize they need Mulder and Scully's help to figure out the real cause of the zombies.
One plot idea could be that Naruto finds himself in a post - apocalyptic world of Dead Rising. He starts to gather survivors and among them are a group of girls who develop feelings for him. Maybe they have to fight off hordes of zombies together while Naruto tries to keep everyone safe. Another idea is that Naruto has some unique abilities in this new world that draw the attention of different female characters, and they form a harem as they rely on him for survival.
In this Naruto - Dead Rising fanfiction, Naruto could team up with some of the survivors in the Dead Rising world. They would be initially skeptical of his strange powers but soon realize his value. Naruto could teach them some of his ninja training techniques to help them better defend themselves against the zombies. And in turn, they could teach him about the unique aspects of the Dead Rising world, like how to find and use the best weapons against the undead.
A cool 'fear the walking dead crossover fanfiction' idea would be a crossover with 'Stranger Things'. The Upside Down could be connected to the zombie outbreak in some way. The kids from Hawkins could team up with the survivors of 'Fear the Walking Dead' to fight both the zombies and the strange creatures from the Upside Down. It would be interesting to see how their different skills and knowledge would work together.
Well, a cool crossover fanfiction idea could be with 'The Witcher'. Geralt could find himself in the world of Red Dead Redemption, hunting monsters in the American frontier. Or, for a more comical crossover, think about a crossover with 'SpongeBob SquarePants'. SpongeBob and Patrick end up in the wild west and their naivete causes all sorts of chaos among the outlaws. Also, a crossover with 'Harry Potter' could be interesting, with wizards and witches showing up in the world of Red Dead Redemption and causing a stir with their magic.
One idea could be that the Winchesters somehow end up in the world of The Walking Dead. They might use their hunting skills to fight the walkers in a different way than the survivors are used to. Maybe they try to find a supernatural cause behind the zombie apocalypse.
