One way to develop the personality of a RWBY Beowolf OC is to think about how it interacts with other Grimm. Does it lead the pack? If so, it might be more dominant and assertive. It could growl and snap at other Beowolfs to keep them in line. Also, consider how it reacts to humans and Huntsmen. Is it more curious than afraid? Maybe it has seen some Huntsmen in action before and is intrigued by their power, so it hesitates before attacking. This kind of personality trait would add depth to your OC in the fanfiction.
Let his experiences mold his personality. If he has had to fight for his survival from a young age, he might be tough and resourceful. On the other hand, if he was sheltered, he could be naive. His interactions with other characters in the RWBY universe can also develop his personality. If he meets a human who treats him with respect despite his Faunus features, it could change his view of humans and make him more open - minded and friendly towards them.
For a RWBY Beowolf OC fanfiction, you could focus on a Beowolf OC that has a connection to a particular location. Say it haunts an abandoned mine in Vale. It could have made the mine its lair and is territorial about it. The OC could have a backstory related to how the mine was once a place of great activity and the negative energy from its abandonment attracted it. The RWBY team stumbles upon this mine during a mission and has to face this territorial Beowolf OC. You could also play with the idea of the Beowolf OC evolving or changing its form as the story progresses, maybe due to absorbing some sort of powerful energy source in the mine.
Think about their values. A Kryptonian OC could value knowledge above all else, like a scholar. So they would be curious, always seeking to learn more, whether it's about Earth or their own Kryptonian heritage. Or perhaps they value family so much that when they come to Earth, they are constantly looking for a family - like group to belong to. This value - driven personality trait can make them stand out. Another aspect is their sense of humor. Maybe they have a very dry, Kryptonian - style humor that others don't quite understand at first, which adds to their uniqueness.
You can start by thinking about their background. If they come from a strict Quincy family, they might be more disciplined and traditional. For example, they would always follow the Quincy code of honor. Another aspect could be their experiences. If they've faced a lot of hardships, like losing their family to Hollows, they could be more reserved and have a strong sense of vengeance.
Think about their past experiences. If they had a traumatic event in their past, like losing their family in a shinobi war, it can shape their personality. They might be cold and distant as a result, or they could be overly protective of those they consider friends in the Akatsuki. You can also show their personality through their interactions with other Akatsuki members. Are they submissive, dominant, or more of a mediator? For instance, if your OC is always trying to stop arguments between members like Deidara and Sasori, it shows they have a peace - loving side.
Base his personality on a strong belief system. Maybe he firmly believes in justice and will go to great lengths to ensure fairness. So when he encounters the Shadows and the dark events in the story, he'll be the one to advocate for doing the right thing, even if it's difficult. His moral compass will be a key part of his personality.
A great way to develop a character is to give them a goal. In a RWBY Killer OC Fanfiction, the goal could be to become the most powerful fighter in the world. To achieve this, they train relentlessly and are constantly looking for stronger opponents. Their fighting style could be a mix of different martial arts they've learned from traveling around the RWBY world. They are also very resourceful, using their environment to their advantage during battles. This character would be interesting as they would constantly be pushing the limits of themselves and those around them.
When developing a RWBY OC for a fanfiction about fathers, you need to focus on multiple aspects. The father's character is crucial. If he was a cowardly figure, the OC might be determined to be brave to compensate. Regarding the OC's character, think about how their father's presence or absence affected them. If the father was absent, the OC could be constantly searching for a father - figure. Their Semblance can also be related to their father. For instance, if the father had a Semblance that could control fire, the OC's Semblance could be something like heat resistance. Also, think about the OC's social circle. Were they isolated because of their father's reputation? Or did they have a lot of friends due to their father's popularity? All these elements will help you create a well - rounded OC.
When developing an RWBY OC for a crossover, consider their culture. If they're from a highly - structured society, they might have different values than the RWBY characters. This can lead to interesting clashes or learning experiences. Also, think about how they adapt to the RWBY world. Are they in awe of the technology or do they find it primitive? Their attitude towards the new environment can say a lot about their character. You should also plan out their character arc. Will they start as a loner and learn to trust others? Or will they become corrupted by power? Mapping out this journey will make your OC more engaging.
You can also develop their relationship through shared secrets. Maybe the OC discovers something about Glynda's past that no one else knows. Instead of using it against her, the OC keeps it a secret. This act of trust makes Glynda more open to the OC. And then they can start to have deeper conversations, which in turn strengthens their relationship.
