One interesting concept could be how the OC from our world adapts to the unique rules and powers in RWBY's universe. For example, dealing with the Grimm and understanding Dust.
Well, perhaps the way the OC's real - world skills translate into the RWBY world. Like if they were a great athlete in our world, they might use those physical abilities in combat in RWBY, but also have to learn how to incorporate things like Aura and Semblance into their fighting style. It's really about the clash and combination of two different worlds' characteristics.
The way OCs are integrated into the fanfiction's world is also fascinating. Sometimes they start as outsiders and gradually become an important part of the story. They can change the power dynamics or relationships within the story. For instance, an OC might befriend a character who was previously isolated, thus altering the character's arc.
One interesting concept could be the unique character interactions. In a harem - style fanfiction set in the RWBY world, the original characters (OCs) might have different dynamics with the RWBY cast. For example, an OC with a special power could form various relationships, like a friendship - turned - romance with a particular RWBY character.
One interesting concept could be unique semblances for original characters. For example, an OC with a semblance that allows them to manipulate time in a limited way, like slowing down opponents' movements for a short period. This can add a new dynamic to fight scenes.
One interesting concept could be the unique powers that a god OC might possess. For example, they could have the power to manipulate time, which would add a whole new dynamic to the RWBY universe. Maybe they can freeze time to prevent a disaster or reverse time to correct a wrong decision.
One interesting concept could be the unique powers that a dragon OC might possess. For example, it could have the ability to breathe different types of elemental attacks like ice, fire, or lightning, which is not common among the regular RWBY characters. Another concept might be the backstory of the dragon OC. Maybe it was once a part of an ancient race of dragons that had a special connection to the world of Remnant before the events of RWBY. Also, the interaction between the dragon OC and the main RWBY characters can be really engaging. How would Ruby, Weiss, Blake, and Yang react to a dragon in their midst? Would they see it as a threat or a potential ally?
Well, a cool concept is the transformation of the OC's personality over time in the reincarnation fanfiction. Since they have memories from another life, they might start off as a bit of an outcast, being different from the others in the RWBY world. But as they interact more and more, they gradually change. Another aspect is the power evolution. Their powers from the past life could merge or transform in this new world. For instance, if they had the power of elemental control in their past life, it could manifest in a new and unique way in RWBY, like being able to control Dust in a way no one else can.
Another idea is an OC gamer who discovers a hidden, game - like dimension within the RWBY universe. This dimension could have its own set of rules and challenges, similar to a video game level, and the OC has to navigate through it using their gaming knowledge.
One interesting concept could be the reincarnation aspect. It allows for the OC (Original Character) to have a new start in the RWBY universe, perhaps with knowledge from their past life that gives them an edge. Another concept might be the harem part, which could lead to various relationship dynamics and character interactions within the story.
In RWBY Star Wars OC fanfiction, an interesting concept is the idea of RWBY characters in Star Wars - style starships. Imagine Ruby Rose flying a ship through an asteroid field, using her speed semblance to quickly dodge obstacles. Also, the concept of combining Dust from RWBY with the technology in Star Wars could lead to some really cool weapon designs. For instance, a blaster that uses Dust to enhance its power or change the type of shot it fires.
Well, of course, the Original Character (OC) from our world is a main character. They are the one who brings the unique perspective from our world into the RWBY universe.
