In RWBY Wizard of Oz fanfiction, the semblances of the RWBY characters might interact in unique ways with the magic of Oz. Weiss's glyphs could combine with Oz's magic spells, creating new and powerful effects. And Blake's shadow clones could be used to outwit the tricky situations in Oz, like fooling the flying monkeys.
Ruby is an obvious choice as she has that lead - character feel. Her naivete and determination are traits that can be paralleled to Dorothy. She would be the one to lead the group through the strange world of Oz.
In a RWBY OC God of Creation fanfiction, the design of the character is crucial. They could be depicted as a benevolent deity, using their powers for the good of Remnant. For example, they might create new safe havens for the people. Or they could be more of a neutral force, simply observing and occasionally intervening in the affairs of the world. The possibilities are endless when it comes to exploring their relationships with the main RWBY characters like Ruby, Weiss, Blake, and Yang.
Make your OC's appearance distinct. It could be something as simple as a unique color scheme for their clothing or a very unusual hairstyle. Also, think about their fighting style. If it's a combination of different martial arts styles or if they use an unconventional weapon, that will make them stand out. For instance, an OC that fights with a whip - sword and combines acrobatic moves from parkour with martial arts would be quite eye - catching in the RWBY universe of 'rwby oc slvr fanfiction'.
A common element is often the merging of the two distinct worlds. For example, the unique weapons from RWBY might be combined with the dark and gothic atmosphere of Bloodborne. Also, the characters' abilities could be a mix. The OC (original character) might have traits from both universes, like a RWBY character with a Bloodborne - inspired power.
One common theme is power and its control. Since Saiyans are known for their great power in the Dragon Ball series, in RWBY OC Saiyan fanfiction, the OC often has to learn to control their Saiyan strength in the RWBY world. For example, they might accidentally cause destruction when they first arrive and then have to learn to tone it down.
One common theme is friendship. Often, the OC and Neo start off as strangers or even enemies and gradually develop a friendship. For example, in some stories, they learn to trust each other through shared battles or experiences.
Character development could also involve the OC learning to control their semblance better. Maybe at first, they can only create small bolts of lightning, but through training and experience, they can summon powerful lightning storms. This growth can be tied to their emotional state as well, becoming more powerful when they are determined or angry.
In a fanfiction, you could explore the origin of the lightning semblance. Maybe it was passed down through generations in the OC's family, but with a curse. The OC has to figure out how to break the curse while using their semblance for good. For example, every time they use the lightning, it weakens their physical health, so they need to find a balance.
Another theme is identity. Faunus OCs usually struggle to define themselves, especially when they have unique abilities or features. They may question their place in society or among their own kind. It's a theme that adds depth to the characters.
