Power struggle is a very common theme. Just like in the original series, the OC lords in these fanfictions often strive for more power, whether it's over a particular region or in the whole of Westeros.
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.
Sure. One interesting 'OC Lord Game of Thrones fanfiction' is 'The Rise of Lord Blackwood'. It focuses on an original character who becomes a powerful lord in the complex world of Westeros. He has to navigate through the political intrigues, much like the main characters in the original series.
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.
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.
One great male OC bastard fanfiction is 'The Bastard of Winterfell's Rise'. It follows an original character who is a bastard in the North. The story is engaging as it shows his struggle to gain acceptance in a society that looks down on bastards. He uses his wits and combat skills to make a name for himself.
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.
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.
Another approach is to have the male OC Targaryen be a bastard son. He struggles with his identity throughout the fanfiction. He is initially shunned by both Targaryen loyalists and those who oppose the old regime. However, through his own strength, intelligence, and a bit of luck, he rises in the ranks. He might form an alliance with a powerful house not typically associated with the Targaryens, like the Mormonts. His journey could be about proving himself worthy of the Targaryen name and heritage, all while navigating the complex politics of Westeros.
