Horror is a common theme. Since 'Evil Dead' is a horror franchise, the crossovers often maintain that spooky atmosphere. The presence of the Deadites, for example, brings in the horror element.
One great 'evil dead crossover fanfic' is the one where it crosses with 'Evil Dead' and 'Army of Darkness'. It combines the horror elements of 'Evil Dead' with the dark humor and action of 'Army of Darkness' in a really unique way. The fanfic does a great job of making the characters interact in a believable and exciting setting.
The theme of the unknown also prevails. When two different fictional universes collide in these crossovers, there are a lot of unknowns for the characters. They don't know the rules of this new combined world, like how the magic or creatures from 'evil dead' will interact with the elements of the other story. This sense of the unknown adds to the overall atmosphere of the fanfiction.
A great 'evil dead crossover fanfiction' could be the one that crosses it with 'Resident Evil'. Picture the survivors in 'Resident Evil' having to deal with the Kandarian demons from 'evil dead' on top of the zombies and bio - weapons they already face. It's a wild concept that many fanfiction writers have explored, with some really creative takes on how the two universes' horror elements can interact.
Another interesting concept for an Ash vs Evil Dead crossover fanfiction is to introduce a new villain that is a combination of different evil forces from both the movies and the show. This super - villain could be immune to some of Ash's usual tactics, forcing him to team up with unlikely allies. The fanfiction could explore how they figure out the villain's weaknesses and ultimately defeat it. It could also include some comical moments, like Ash's one - liners in the face of danger.
Survival is a very common theme. Whether it's characters from different shows trying to survive in The Walking Dead's post - apocalyptic world or vice versa.
The combination of different powers and abilities. RWBY characters have their unique semblances and weaponry, and Resident Evil has its own set of weapons and mutated creatures. In a crossover fanfic, seeing how these elements interact, such as a RWBY character using their semblance to fight a Resident Evil boss, can be very exciting. For instance, Blake's shadow clones could be used to confuse a Tyrant. Also, the exploration of how the two different storylines and settings merge. Whether it's the Umbrella Corporation getting involved in RWBY's world or RWBY characters stumbling into a Resident Evil - like scenario in their own world, it creates a whole new set of possibilities for the story.
Another one is 'Resident Remnant'. In this fanfic, the writers do a great job of integrating the lore of both series. They create a scenario where the bioweapons from Resident Evil are introduced to RWBY's world, and the story follows how the characters adapt and fight back. It has some really cool action scenes that are a blend of RWBY's fast - paced combat and Resident Evil's survival horror elements.
Survival is also a big theme. Just like in Resident Evil, characters from both universes have to find ways to survive in a new and dangerous situation. For instance, Naruto characters may have to deal with the bio - weapons and traps of the Resident Evil world. Inversely, Resident Evil characters might struggle to survive in a world full of ninjas with superhuman abilities.
It allows for character development in new contexts. If Resident Evil characters are put into a post - apocalyptic world of a different kind, they have to adapt and grow in different ways. Also, different settings can enhance the existing traits of the characters. For instance, in a steampunk crossover, their skills and personalities are explored in a whole new light with new challenges.
