It could create really complex and thought - provoking storylines where characters have to navigate different ethical and power - related situations.
Another concept might be the exploration of different environments. Maybe a crossover where the 'rain world' setting is merged with a post - apocalyptic cityscape from another story. This could lead to new challenges and survival scenarios for the characters.
One interesting concept could be the crossover of different species from 'rain world' with characters from other universes. For example, the slugcat interacting with a magical creature from a fantasy world.
One interesting concept could be exploring different endings for the characters in Rain World. For example, what if the slugcat found a way to completely change the ecosystem? Another could be delving deeper into the backstories of the various creatures. Maybe there's a fanfic that shows how the lizards evolved to be such fierce predators. And some fanfics might focus on alternative relationships between the different species, like a symbiotic relationship that doesn't exist in the original game.
The character interactions can be really engaging. Characters from 'world trigger' might form unexpected alliances or rivalries with characters from the crossover universe. This can lead to new story arcs and development for all the characters involved.
One interesting concept could be the combination of different character abilities from the original 'danmachi' and the crossed - over universe. For example, if it's a crossover with a magic - heavy world, seeing how the 'danmachi' characters adapt to and use new forms of magic would be really cool. Another concept might be the cultural clashes. Characters from 'danmachi' might have different values and social norms compared to the characters from the other world in the crossover, and exploring how they interact and deal with these differences can make for an engaging story. Also, the new relationships that form between characters from both universes, whether it's friendship, rivalry or even romance, add depth to the fanfic.
One interesting concept could be a crossover with other Victorian - era related works.

For example, a crossover with Star Trek might involve the Voltron team having to navigate the complex politics and technology of the Federation. Another concept could be a crossover with a more fantasy - based universe like Lord of the Rings, where the Voltron lions could be seen as powerful magical beasts in Middle - earth. And in a crossover with a superhero universe like the Marvel Cinematic Universe, the Voltron pilots could team up with the Avengers to fight a common enemy.
One interesting concept could be the interaction between BlackWarGreymon and characters from different universes. For example, how he would react to meeting characters with very different moral compasses or powers. Another concept might be his journey in a new world created by the crossover, facing new challenges and making new alliances or enemies.
Well, in 'jojo crossover fanfic', a common concept is the fusion of stands. Imagine if Star Platinum and Gold Experience combined their powers in some way. This would lead to really creative battles and problem - solving within the fanfic's plot. Also, crossovers might include Jojo characters in different settings like modern day New York instead of their original locations, which is super cool.
One interesting concept could be the crossover with other popular anime. For example, crossing over with 'Your Lie in April' might bring a unique blend of the two stories' emotional tones.
