Another great option could be a new character, like Thoren. He was born into a family of blacksmiths, so he had easy access to different types of swords. He experimented with different blade weights and lengths, which gave him an edge in combat. He has a reputation for being able to use any sword effectively and can switch between different styles mid - fight. This adaptability makes him a formidable swordsman in the fanfiction world.
One possibility could be a character named Ser Aric. He was trained by an old, reclusive master swordsman in the mountains. He combines speed and precision in his swordplay, and his unorthodox style often catches his opponents off - guard.
In a Game of Thrones OC swordsman fanfiction, there are several contenders for the most formidable opponent. One could be the Mountain. His brute strength and combat experience would pose a great challenge. He's known for his brutality in battle and his large size gives him an advantage in close - quarters combat.
One great 'Game of Thrones OC Male Fanfiction' is 'The North's New Son'. It has a well - developed male character who is thrust into the complex politics of the North. He has to navigate the loyalties and rivalries, which makes for an exciting read.
Perhaps a curved sword similar to what the Dothraki use. This type of sword allows for quick slashing attacks, which could be effective in a more fluid and mobile fighting style. The OC swordsman could have learned this style from traveling and fighting with the Dothraki or from a Dothraki - trained mentor.
Margaery can also be a symbol of hope or change in fanfictions with a male OC. If the male OC is disillusioned with the current state of Westeros, Margaery could represent a new way forward. Her charm and intelligence can inspire the male OC to support her in her plans to reform the kingdom. Their relationship then becomes a driving force for the plot, as they strive to make Westeros a better place while also dealing with their own personal feelings for each other.
I think it could be the blacksmith OC who has a strong moral code. For instance, an OC who refuses to make weapons for evil lords or sells his work only to those who he believes will use it for good. This type of character adds depth to the fanfiction and can be very appealing to readers who like complex and morally upright characters.
He can have a unique weapon. For instance, a weapon that has some magical property or a very strange design that no one has seen before. This would make him instantly recognizable on the battlefield.
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.
First, you need to have a clear understanding of the 'Game of Thrones' universe. Know the politics, the different houses, and the cultural norms. For your male OC, give him a unique backstory. Maybe he's from a small village affected by the wars or he has a special skill passed down in his family. Then, create interesting relationships for him. He could be an ally or a rival to the main characters.
