Another theme is the exploration of new abilities. When the characters cross over, they might learn new skills from the other world. For example, a Resident Evil character could learn some basic ninja techniques, or a Naruto character could figure out how to use some of the Resident Evil weapons or technology.
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.
Survival is a very common theme. Since Resident Evil is about surviving in a world full of bio - horrors, when crossed over with other universes, the characters often have to adapt and survive in new and even more dangerous situations.
Survival is a very common theme. Just like in the original 'Resident Evil 2', when characters from different universes cross over, they still have to fight to survive the zombie - infested Raccoon City or deal with the bio - weapons.
The theme of redemption often pops up too. Maybe a character from another franchise who has made mistakes in their own world gets a chance to redeem themselves in the Resident Evil 6 crossover. Or a Resident Evil character has a chance to make up for past failures by working with new allies from the crossover. It adds depth to the characters and the overall story.
Survival is a common theme. Whether it's crossing over with another survival - horror franchise or a more action - oriented one, the characters are often faced with new threats and have to find ways to stay alive in the Resident Evil 5 crossover fanfiction. For example, when crossed with a post - apocalyptic world like in Fallout, they need to find resources and shelter while fighting off the Resident Evil enemies.
Survival is a very common theme. Just like in the original Resident Evil 7, characters in crossovers are often faced with life - threatening situations. They have to find ways to stay alive in the face of the various horrors, whether it's the Molded or the threats from the other franchise in the crossover.
A common theme is the clash of different universes. Since it's a crossover, you often see Nemesis from Resident Evil entering a world with different rules, creatures, and characters. Another theme is power struggle. Nemesis is a powerful entity, and when put in a new environment, there's often a struggle for dominance.
Character development is also a big theme. Writers often use the crossover situation to explore different aspects of Leon's character. For example, how he copes with being in a completely different world. And of course, there's the theme of combat. Leon is a skilled fighter, and in crossovers, his combat skills are put to the test against new and unexpected foes.
Another theme is the exploration of different worlds. Fanfictions might take Naruto characters into the Resident Evil world or vice versa. This allows for a lot of world - building and exploration of how the two very different universes would interact with each other. For instance, how would Naruto's Konoha village function in a world full of bio - hazards? Or how would the Umbrella Corporation react to the presence of ninjas?
Another theme is the relationship between characters. The 'bodyheat' can be a metaphor for the closeness and intimacy (not necessarily in a romantic way) that develops between survivors. They are forced to be close to each other, and this can lead to complex relationships.
One common theme is the clash of two different universes. The bright and colorful world of Pokemon colliding with the dark and dangerous Resident Evil world. Another theme could be survival, just like in Resident Evil, but now with the added element of Pokemon. For example, trainers and their Pokemon having to fight for their lives against bio - threats.
