You can start by thinking about their backstory. If your OC has a tragic past, like being abandoned by their Gem group, they might be more guarded and cautious. For example, they could be slow to trust others, especially new Gems or humans they meet. Another way is to consider their role. If they're a warrior - type Gem, they could be bold and fearless in battle but a bit clumsy when it comes to expressing emotions outside of combat. You can also give them quirks, like always humming a particular tune when they're nervous or having a fascination with human objects like paper airplanes.
To develop a unique personality for your Steven Universe OC, consider their goals and dreams. If your OC dreams of reuniting all the scattered Gems from their former colony, they'll be determined and focused. They might be a bit single - minded at times, which could cause friction with other characters who have different priorities. Their personality can also be influenced by their appearance. For instance, if they have a very bright and colorful Gemstone, they could be outgoing and energetic, always trying to spread positive vibes. But if their Gemstone is dull or cracked, they might have an underlying sense of insecurity that they try to hide with bravado.
You can start by thinking about their home planet's culture. If their planet is highly competitive, the OC might be ambitious and always striving to be the best. For instance, if they're from a planet where music is the most important aspect of society, they could be very melodramatic and express themselves through song and rhythm.
Start with their appearance. Give them a distinct color scheme that sets them apart from the other Diamonds. For instance, a purple - blue Diamond. Then think about their personality. Maybe they're more introverted and prefer to observe rather than directly control like the other Diamonds.
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.
First, give each character a distinct personality trait. For example, if one of the characters in the harem is a gem, maybe she's overly confident but has a soft heart deep down. For the OC, think about their backstory. If they're from another planet, how does that affect their view of Earth and the gems here? Also, consider their relationships with each other. Do they have inside jokes or shared memories? These things can help develop the characters.
Start by giving your giant OC a distinct personality. For example, if they are gentle - natured, show how they interact with the smaller beings in the Steven Universe in a careful and kind way. If they are more brash, show how their actions might cause some initial conflict. Also, think about their backstory. Were they always a giant? Or did something happen to make them this way? This will help shape their character.
First, think about their origin. It could be something completely different from Superman's. For example, instead of being born with powers, they could gain them through a magical encounter. Then, focus on their personality. Maybe they're more cynical than Superman because of their experiences. Also, consider their appearance. They could have a distinct costume or physical features that set them apart.
Start with their appearance. Decide if they have a unique gem placement or color that sets them apart. For example, if they're a new type of gem, maybe their gem is a different shape. Then, think about their personality. Are they shy like Lapis was at first? Or are they outgoing and adventurous? Their backstory is also crucial. Maybe they were created for a special purpose but that purpose was lost over time. This could lead to them having a sense of being lost which Lapis can relate to.
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.
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.
Their relationship could develop in a unique way if Lars starts to learn about Steven's gem heritage more deeply. For instance, Lars could become interested in the history of the gems and start to study it with Steven. This shared interest could bring them closer together.
