One way is to give him a moral code that is different from the other vampires. Maybe he refuses to feed on the innocent, which sets him apart. This moral stance will lead to conflicts and decisions that show his strength of character. His reaction to stress or danger is also key. Does he remain calm and calculating, or does he become impulsive? And don't forget about his emotional side. If he is a very passionate character, it will show in his actions and how he interacts with others. For example, if he falls in love, his all - consuming passion could lead him to take great risks or make sacrifices.
First, consider giving him a clear goal or motivation. For example, if he wants to gain power within the vampire hierarchy, it will shape his actions and decisions. Also, think about his past experiences. If he had a traumatic event in his past, like losing a loved one to a vampire hunter, it could make him more guarded or vengeful. His values are important too. If he values loyalty above all else, he'll act differently than a character who values freedom more.
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.
First, decide on her main motivation. For example, if she's driven by a desire for knowledge, she might be constantly seen reading books in the library or asking the smartest characters lots of questions. This will make her seem inquisitive and determined.
First, consider her backstory. If she grew up in a difficult situation, like losing her family at a young age, it could shape her into a tough and independent character. Her relationships with other characters are also important. If she constantly challenges Simba's leadership in a respectful way, it shows she's confident. You can also show her personality through her actions. For instance, if she's the first to volunteer for a dangerous mission to save the pride, it shows her courage. And don't forget about her sense of humor. A lioness who can crack jokes even in tough situations can be really endearing.
Show their differences and how they complement each other. The female OC might be more bold and outspoken, while Yui is more reserved. The OC can encourage Yui to stand up for herself more, and Yui can teach the OC about the subtleties of dealing with the vampires. Their different personalities can create an interesting dynamic in the fanfic and help develop their relationship.
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 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.
Think about his backstory. If he grew up in a rough part of the Isle of the Lost, he might be street - smart and a bit cynical. For example, if he had to steal to survive, he would be very resourceful. Another aspect is his relationships. If he has a best friend who is always getting into trouble, he might be the more level - headed one. Also, consider his hobbies. If he likes to draw, he could be more of an observer and have a creative side that sets him apart from the more action - oriented characters.
Give him some contradictions. For example, he could be really strong and confident in battle but very shy and awkward in social situations outside of combat. Maybe he has a fear of heights even though he can fly with his magic. This creates depth and makes him more interesting.
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.
