The personality of a male Stark OC can be developed in multiple ways. First, look at the environment he grows up in. If he grows up in the cold North, he might be more stoic and resilient. His family's influence is crucial too. If his father was a strict disciplinarian, he could be very respectful and obedient, but also have a rebellious streak deep down. He could also be influenced by the magic and superstition in the Game of Thrones world. Maybe he has a connection to the old gods and is more spiritual than other Starks. This could affect his decision - making and how he views the world around him. For example, he might see signs from the gods in everyday events and base his actions on those interpretations.
Think about his experiences. If he has witnessed the fall of his family or has been persecuted for being a Targaryen, it could make him either vengeful or more cautious. He could be a brooding type, constantly thinking about how to restore his family's honor. Or he could be more of a diplomat, trying to win over his enemies through charm and negotiation rather than brute force, seeing the futility of constant war. All these aspects can be developed based on the events you plan for him in the fanfiction.
Consider their upbringing. If they were raised away from the main Lannister stronghold, they might have a different set of values. Maybe they were raised by a kind - hearted servant who taught them to be more empathetic. So their personality could be a mix of Lannister pride and this new - found empathy. They could be conflicted between loyalty to their family and doing what is right according to their own conscience.
To develop a male OC Baratheon, start with his physical appearance. Maybe he has the typical Baratheon black hair and blue eyes, but with a scar on his face from a battle. Then think about his personality. He could be proud like most Baratheons, but also have a sense of humor.
You can start by considering the nature of dragons in the Game of Thrones universe. Dragons are powerful, proud, and often have a bit of a wild streak. For your OC, you could make it more curious than the average dragon. Maybe it's interested in exploring new places, which leads it to interact with different characters. For example, it might fly off on its own to check out a strange smell or a shiny object in a far - off land.
One idea for a male OC in the Stark family could be a long - lost cousin. He could have been sent away as a child for some reason, perhaps due to a political intrigue within the family. He might be a skilled swordsman, trained in secret by an old knight who knew his true identity. His personality could be a mix of the traditional Stark honor and a bit of a roguish charm, which he developed during his time away from the family. This would make him an interesting addition to the Stark family dynamics in a fanfiction.
An OC Stark might be more politically astute than the original characters. They could form different alliances, like making a deal with the Iron Bank that gives the North more financial power and influence. This would shift the power dynamics not only in the North but also across Westeros. The original plot of various houses vying for the Iron Throne would be affected as the North becomes a stronger and more independent force.
One way to develop his personality is by his reactions to different situations. If he loses a fight, does he get angry and vow revenge or does he take it as a learning experience? Another aspect is his interaction with other characters. If he meets Ken, does he show respect or is he competitive? Also, his values can shape his personality. If he values honor above all, he might refuse to fight dirty.
Robb Stark would likely become more cautious. After narrowly escaping death at the Red Wedding, he would know that his enemies are ruthless. This would make him more calculating in his military campaigns and political moves. He might be less trusting, especially of those who have shown signs of betrayal in the past.
Another option is to make him a really quiet and brooding type. Maybe he has a dark past that has made him closed - off. His OP powers are a burden to him because he's afraid of hurting others. So he keeps to himself most of the time. As the story unfolds, he slowly opens up to his squad mates as they prove themselves trustworthy and he realizes he can't face his problems alone.
Often in fanfiction, Jon Stark is given more emotional depth. He may struggle with the weight of his name and the expectations that come with it. This internal struggle can lead to him making different choices. He could decide to abandon the Stark name for a while to find his own identity, and then come back to it with a new understanding of what it means to be a Stark. This journey of self - discovery is a major aspect of his character development in many fanfictions.
