What are some interesting plot ideas for an RWBY Ancient Kingdom fanfic?

Well, a plot could be centered around an ancient tech that was hidden away because it was too powerful. The characters accidentally stumble upon it. For example, it could be a technology that can open portals to other dimensions. They then have to deal with the consequences of opening these portals, like new and dangerous enemies coming through. Also, the fanfic could explore how this ancient technology was created in the first place. Was it made by the same people who created the Dust? Or was it from an even more ancient civilization?

Perhaps there could be a plot where the Organization XIII members from Kingdom Hearts have an interest in the Relics from RWBY. They start to manipulate events in the RWBY world to try and get their hands on these powerful artifacts. The RWBY characters, suspecting something is amiss, team up with Donald and Goofy who have also arrived in their world. Together, they have to figure out the Organization XIII's plan and stop them before they can steal the Relics.

A cool plot for 'the last kingdom fanfic' might be to have a character be transported back in time to a crucial moment in the kingdom's history. They would have the knowledge of what's to come but struggle to convince others to believe them. This could lead to all sorts of interesting twists. Or you could write about a character who is secretly training a group of women to be warriors in a society that doesn't really accept that. It would be about breaking gender norms and the challenges they face in a war - torn world.

Another interesting approach is to have a character bond with an ancient weapon in a unique way. For example, a character might find an ancient weapon that seems to have a mind of its own. As they interact, the weapon reveals its powers and secrets only to that character, and they form a special alliance to face a great threat in the RWBY universe.

One idea could be exploring a new character's journey in the RWBY world. Maybe a character from a different kingdom who has unique abilities and must team up with the main RWBY characters to face a new threat. Another plot could involve time travel, where a character goes back in time to change a crucial event in RWBY's history. A third idea is a story focused on the Grimm's origin and how to potentially find a way to permanently stop their creation.

Maybe in the RWBY Future Fanfic, the characters could explore new kingdoms. They might discover hidden secrets about the origin of Dust and how it can be harnessed in more powerful ways. This could lead to new power-ups for the characters and also introduce new allies and enemies.

A plot could revolve around a new threat that affects both universes. So, the RWBY characters and the Titanfall pilots have to team up. The RWBY characters' creativity in combat combined with the Titanfall pilots' skills in mech combat could make for an epic battle against the common enemy. There could be some cultural clashes and misunderstandings at first, but as they get to know each other, they become a formidable force.

One idea could be exploring an alternate universe where the characters' roles are reversed. For example, the villains are the heroes and vice versa. Another plot could involve a new Grimm threat that is unique to the Mirrorverse, forcing the RWBY characters to adapt their fighting styles. Or perhaps a story about a character getting lost in the Mirrorverse and having to find their way back while facing mirror versions of their friends and foes.

One plot idea could be that a character from RWBY gets transported to the world of Overlord. They might have to navigate the power - hungry and often dangerous world, trying to find a way back home while also dealing with the various powerful beings in Overlord. For example, Ruby could end up in the Tomb of Nazarick and have to figure out how to interact with the Floor Guardians without getting killed.

One idea could be exploring a different backstory for one of the main characters. For example, Ruby could have grown up in a more isolated part of Remnant and had to learn combat skills in a very different way. Another could be a time - travel plot where a character goes back in time to change a major event in the RWBY universe. Maybe they try to prevent the fall of Beacon earlier in the story, which would have a huge impact on all the characters and their relationships.
