One idea could be to have the characters from RWBY encounter the Beasts in a shared realm. For example, Ruby could be intrigued by the unique abilities of the Beasts and try to learn from them while also teaching them about her own world's Dust magic. Weiss might initially be cautious but then find common ground in the Beasts' sense of honor. Blake could relate to the Beasts' more wild and primal nature, and Yang would be eager to test her strength against them.
In a fanfic, the crossover could start with a strange portal opening up and sucking some of the RWBY characters into the Beast world. They would be disoriented at first but quickly adapt. They could meet different types of Beasts, some friendly and some hostile. The RWBY characters would have to figure out how to get back home while also dealing with the various challenges in this new world. Ruby's leadership would be put to the test as she tries to keep everyone together and find a way back.
First, understand the lore of both RWBY and the Beasts. This will help you create a more believable crossover. For example, know the Semblances in RWBY and the powers of the Beasts. Second, focus on character development. Show how the RWBY characters change when interacting with the Beasts and vice versa. Third, create an engaging plot. It could be a simple adventure or a more complex mystery involving both worlds.
Perhaps in the fanfic, there's a human who is a collector of rare weapons. When he hears about Crescent Rose, he becomes obsessed with adding it to his collection. He tries all sorts of devious methods to get his hands on it, like tricking Ruby or stealing it during a battle. However, his actions have consequences as the other RWBY characters come after him to retrieve the weapon.
Ruby could interact with the main characters from Red vs. Blue. Maybe she tries to teach them some of her scythe - fighting techniques, and in return, they show her some of their military - style combat strategies. It would be an interesting exchange of skills.
One idea could be to have the keyblade wielder from the original Keyblade world end up in a high - fantasy world like Middle - earth. The keyblade could be seen as a powerful and mysterious weapon, and the wielder might have to team up with characters like Aragorn to fight against Sauron. Maybe the keyblade has unique powers that can help turn the tide in battles against the orcs.
It's inappropriate because it combines the RWBY franchise with hentai, which goes against the family - friendly and positive image that RWBY usually promotes. Hentai content is not something that should be associated with mainstream or even most fan - created works.
A cool plot for a Rosario Vampire crossovers fanfic could be a time - travel scenario. The characters go back in time to the era when vampires were first created. They could meet the original vampire lords and learn about the true origins of their kind. This could also lead to a conflict as they might accidentally change the course of vampire history. Or perhaps there could be a crossover with a magical girl series. The Rosario Vampire girls could learn some new magical powers from the magical girls and use them to fight off a new threat that is immune to their normal vampire and monster abilities.
One idea could be exploring the Beast's past more in - depth. Maybe show his life before the curse and how it affected his personality. Another could be a modern - day retelling where Belle is a scientist trying to find a cure for the Beast's curse.
A common 'rwby crossovers fanfic' is the crossover with the world of Pokémon. RWBY characters could be trainers, and their semblances could have unique interactions with Pokémon abilities. For instance, Blake's shadow clones could be used in Pokémon battles in an interesting way. These crossovers often explore how the RWBY characters would adapt to the new world they are in and how their relationships would develop within that new context.
In RWBY Naruto crossovers, often you'll find fics that focus on the training aspects. Since both series have a strong emphasis on character growth through training. Naruto's intense training regimens could be introduced to the RWBY characters, and they could learn new ways to improve their combat skills. Maybe Weiss could learn some chakra control techniques to enhance her Glyphs. Another aspect is the teamwork. The RWBY teams and Naruto's squads have different dynamics, and when combined in a fanfic, it can lead to some great character development and exciting plot twists.
You can start by studying how the characters in RWBY interact in the original show. Then, when role - playing in the fanfic, try to mimic those styles while also adding your own twists. For instance, Weiss is often formal and a bit uptight at first. If your character is interacting with her, they could initially clash due to different personalities but then gradually find common ground. Additionally, consider the different weaponry and semblances of the characters. These can be used to create unique and exciting action - based interactions during the role - playing.
