What are some interesting plot ideas for a 'Blazblue x Persona x RWBY' fanfic?

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.

A more action - oriented plot could involve Yu and Naoto being targeted by a new enemy that is related to the Shadows. They have to use their Personas together to fight this new threat. During their battles and the time they spend preparing for them, they grow closer. Yu might use his natural leadership skills to protect Naoto, and Naoto's intelligence could help them strategize. This shared danger could bring out their feelings for each other.

Maybe Elizabeth discovers a prophecy about Minato and she becomes determined to protect him at all costs. This could lead to a lot of action - packed scenes as well as some really tender moments between them. For example, when she has to shield him from a powerful enemy attack.

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.

Maybe the Forerunners in the Halo universe somehow cross paths with the Dust - the energy source in RWBY. This could lead to a power struggle or an alliance based on the unique properties of Dust. The characters from RWBY might use their Semblances in combination with Halo technology for some really cool battles.

Well, a 'naruto x rwby fanfic' could center around a training arc. Imagine Naruto training the RWBY team. He could help Ruby improve her speed and combat skills by teaching her some of his ninja movement techniques. Yang could learn from Naruto how to better control her temper during battles, similar to how Naruto had to control his Nine - Tails' chakra. Meanwhile, the Naruto characters could also be learning about the Grimm and how to fight them. They could incorporate their ninja tools and jutsu to combat these new and strange enemies from the RWBY world.

Well, an interesting plot could involve an OC that is a transfer student, just like the protagonist. But this OC has a hidden past related to the Metaverse. Maybe they were experimented on by a shadowy organization in their home country, and this gives them a different perspective on the Metaverse compared to the Phantom Thieves. Their goal could be to find out who was behind those experiments and get revenge. Along the way, they form a bond with the group and learn new ways of using their powers.

Perhaps there could be a situation where the Grimm from RWBY start to invade the world of Genlock. The Genlock team, with their diverse skills and abilities, would have to learn about the Grimm from the RWBY characters in order to fight them effectively. And in return, the RWBY characters could learn about Genlock's technology and combat strategies. For example, they could figure out how to use the Genlock's mech - like suits in their battles against the Grimm. It would be a great opportunity for character development as they interact and adapt to each other's ways.

One idea could be that Terumi and Trinity are forced to team up against a common enemy. Maybe a new, powerful force emerges in the BlazBlue universe that threatens both of their interests. They start off distrusting each other but gradually learn to work together and in the process, develop an unexpected bond.

Well, a cool concept in RWBY x Undertale fanfic could be the exploration of the different worlds. RWBY has its own complex world with Grimm, Huntsmen, and Kingdoms. Undertale has the Underground with its distinct areas and monsters. A fanfic could involve characters traveling between these two worlds and the culture shock they experience. Also, the magic systems in both could be merged in interesting ways. The Dust in RWBY and the magic in Undertale might interact in ways that create new powers or abilities for the characters.
