An engaging Persona and RWBY fanfic can be created by exploring the themes of both. Persona often deals with self - discovery and facing one's inner demons, while RWBY is about teamwork and fighting for a better world. You could create a story where the characters from both universes have to work together to overcome a common threat that embodies both these themes. For instance, a powerful Grimm that can only be defeated if the RWBY characters understand their inner selves like the Persona characters do. In terms of writing, make sure to give each character their own voice. Don't make the RWBY characters sound like Persona characters and vice versa. This will make the fanfic more believable and engaging.
One popular trope is the 'fish - out - of - water' situation. For example, a Persona character suddenly finding themselves in the RWBY world and having to adapt to the new rules, like dealing with Grimm instead of Shadows. Another is the power - exchange trope. The RWBY characters might gain the ability to summon personas, or the Persona characters could learn to use Dust. Also, the team - up trope is common. Characters from both universes joining forces to fight a greater evil, whether it's a powerful Grimm or a super - powerful Shadow.
One idea could be that the RWBY characters enter the Metaverse from Persona. They might have to face their Shadows, which could be related to their Grimm - fighting fears or personal insecurities. For example, Ruby could face a Shadow that represents her fear of not being able to protect everyone.
It could be a blend. RWBY characters have their weapon - based combat and Semblances. Persona characters have their Personas with various elemental attacks. Maybe the Personas could enhance the RWBY characters' weapons or Semblances. For instance, a Persona with fire abilities could make Yang's punches even hotter and more powerful.
Well, to start a RWBY Persona OC fanfic, you should begin with a strong concept for your OC. Decide on their weapon, for example. In RWBY, weapons are really important and unique. Then, you can start thinking about how your OC would fit into the different teams or groups in RWBY. Do they join an existing team? Or form their own? Once you have these basic elements, you can start writing the first scene. Maybe it's your OC arriving at Beacon Academy or encountering one of the main characters in a dangerous situation. Just let your creativity flow and don't be afraid to deviate from the canon a bit as long as it makes sense for your story.
A possible plot could be that there is a strange energy disturbance that starts to merge the three universes together. Characters like Ragna from Blazblue, the Persona users, and Team RWBY find themselves in a strange new world that is a mix of all three. They must figure out what is causing this and how to stop it. Maybe there are also new enemies that are created from the combination of the different mythologies and technologies of the three universes. For instance, Grimm with the ability to use Persona - like powers or Blazblue - style Ars Magus. It would be a great opportunity for character development as they learn to work together despite their differences.
One common mistake is making the OC too overpowered. In RWBY, all characters have their limits and weaknesses. If your OC can defeat every Grimm or character easily, it becomes less interesting. Another mistake is ignoring the existing RWBY lore. For example, the rules about Aura and Semblance. If your OC's abilities don't fit within these concepts, it can seem out of place. Also, poor character development is a big no - no. Just having a cool - looking OC isn't enough. You need to give them depth, like real - life people have emotions, motives, and flaws.
Ragna from Blazblue and Ruby from RWBY could be an interesting pairing. Ragna is a brooding anti - hero with a powerful combat ability, while Ruby is an optimistic and energetic young huntress. Their different personalities could lead to some great character interactions, like Ragna being a bit cynical at first but slowly being influenced by Ruby's positive attitude. Another interesting pairing could be a Persona user, say Yu from Persona 4, and Jin from Blazblue. Jin is a cold and reserved swordsman, and Yu could use his empathetic nature and Persona powers to try to break through Jin's icy exterior. And for a third pairing, Blake from RWBY and a Persona user like Akechi from Persona 5. Blake has her own secrets and a complex past, and Akechi's dual nature could create an interesting dynamic as they both have things they are hiding.
One possible plot could be that the characters from RWBY end up in the Persona universe and have to learn how to use Personas to fight the Shadows. For example, Ruby could discover her Persona is related to her speed and scythe skills, and she uses it to quickly dispatch enemies. The team would also have to deal with the social aspects of the Persona world, like building relationships to strengthen their Personas.
Ruby would be all wide - eyed and enthusiastic. She'd be like 'Whoa, this is so cool! The battles and the cool powers in this fanfiction are amazing!'.
