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.
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.
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.
The shared history they have from the events of Resident Evil 4. All the near - death experiences, the trust they had to build in each other in a world full of bio - threats. Fanfics can explore how that shared history affects their relationship in new and different ways. For instance, they might have nightmares about the events and find comfort in each other's arms. There are also the different cultures and backgrounds they come from that can add depth to their relationship as it develops. Leon's more military - style upbringing compared to Ashley's privileged life before the horror started.
One interesting Resident Evil RWBY fanfiction could be where the characters from RWBY face the bio - horror threats of Resident Evil. For example, Ruby could use her scythe skills to fight off zombies or mutated creatures. Another might involve the Resident Evil characters getting some of RWBY's powers, like Leon Kennedy having some semblance of super speed.
The combination of different universes. In a Destiny RWBY crossover, you get to see the high - tech and space - faring elements of Destiny meet the more medieval - like, yet also magical world of RWBY. For example, Destiny's guns and supers against RWBY's weapons and semblances.
A good Resident Evil OC fanfic often has a well - developed original character. For example, the character should have a unique backstory, like being a survivor of a previous Umbrella experiment. This makes the character more interesting and relatable.
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.
Well, it could be the unique pairing of Claire and Annette. Their different personalities and roles in the Resident Evil universe can create interesting dynamics in the fanfic.
The female tyrant's mystery is a big draw. We don't know much about her origin in the official lore, so fanfic writers can create their own unique backstories. For example, they can explore if she was once a normal human before being turned into a tyrant.
One interesting storyline could be an alternate take on Claire's adventure. Maybe she teams up with an unlikely ally, like a surviving Umbrella scientist who has a change of heart and helps her fight the zombies. This could add a new dynamic to the story.
