Well, a cool concept in RWBY and RVB crossover fanfic is the technology exchange. RVB has advanced military tech, and RWBY has Dust - based technology. Imagine a situation where the teams in RWBY start using some of RVB's weapon systems or vice versa. Also, the different team dynamics could lead to some interesting storylines. The tight - knit teams in RWBY might learn from the more chaotic but effective teamwork in RVB.
A great idea for an RVB RWBY crossover fanfic could be a tournament - style story. Characters from both universes are forced to participate in a huge tournament. This would allow for a lot of different match - ups between the characters. The Reds and Blues' comical and sometimes unorthodox fighting styles would contrast with the more refined and trained fighting styles of RWBY characters. It could also lead to some interesting friendships or rivalries forming during the tournament.
For the RVB characters in the RWBY world, you can have them develop new skills related to Aura and Semblances. For example, Tucker could discover his Semblance is something like enhanced swordsmanship. And they could also develop in terms of their understanding of the RWBY universe's values.
One challenge is character integration. The characters from RVB and RWBY have very different personalities and backstories. For example, the Reds and Blues are often comical and more laid - back compared to the RWBY characters who are more on a mission to save their world. So, making them interact in a believable way can be tough.
There's a crossover fic called 'Colors of Combat'. In this story, the Reds and Blues find themselves in the RWBY universe and have to adapt to the new rules and powers there. It has great character development as they learn from the RWBY characters and vice versa. The story also has some really cool fight scenes that blend the combat styles of both series.
Ruby and Church could be an interesting pairing. Ruby is young and idealistic, while Church is often sarcastic and has a more jaded view. Their interactions could be really fun to read. Another would be Weiss and Tucker. Weiss is from a high - society background and Tucker is, well, Tucker. The contrast in their personalities and upbringing would make for an engaging story.
They'd likely be confused at first. The settings and characters of RVB are so different from their own. But Ruby might get excited about new combat ideas. She loves new ways to fight. Yang would probably laugh at any funny dialogues. Weiss might be a bit dismissive as it's not the high - class literature she prefers. Blake could be the most open - minded, seeing potential in the different storytelling.
Well, they might find it really strange at first. RWBY has its own unique world and story, and Red vs Blue (RVB) fanfic would be quite different. Ruby might be really interested in the action parts if there are cool battles described in the fanfic. Weiss could be critical of the writing style compared to the literature she's used to. Blake might see some parallels or differences in the character relationships, and Yang would probably enjoy any parts with humor or sass.
One main theme is often cooperation. Since it involves two different groups of characters, they usually have to learn to work together despite their differences. For example, the RWBY characters with their unique semblances and the RVB characters with their military tactics need to combine their strengths.
There might be a fanfic where the technology from RVB is introduced to the world of RWBY. Like, Caboose could accidentally bring some of the Freelancer's advanced weaponry to Remnant. This would cause a stir as the RWBY characters try to figure out how to use or counter this new technology. It could lead to some humorous moments as the RVB characters try to explain the functions in their own, often-confusing ways.
