He could also play the role of a healer. In a world full of wars and diseases, a male OC with exceptional healing skills would be very valuable. He could be in a small town when a plague breaks out. He uses his knowledge of herbs and ancient healing techniques to save as many people as he can. This would make him a hero in the eyes of the common people, and perhaps catch the attention of a powerful noble who wants to use his skills for their own purposes.
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.
The OC Greenseer could act as a guide. They might use their visions to lead characters to hidden treasures or safe havens. For instance, they could show a group of refugees the way to a secret valley where they can survive the winter and the war.
He could play the role of a hero. In a fanfiction, he may be the one to save the Iron Islands from a great threat, like an impending invasion or a natural disaster. He uses his wits and courage, which might be different from the typical brute force associated with the Greyjoys. He could also be a diplomat, forging new alliances for the Iron Islands, like making a pact with the Lannisters to gain wealth and protection in exchange for naval support.
He could be a rebel. Tired of the Bolton family's traditional ways, he might try to change the family's reputation. He could be a force for good in the North, protecting the smallfolk from the usual Bolton brutality.
Petyr Baelish often plays a devious role in OC fanfiction. He might be the mastermind behind many plots. For example, he could be using an OC to gain more power in King's Landing.
A female Stark OC could play the role of a peacemaker. For instance, if there are disputes between different Stark siblings or between the Starks and other houses. She could use her diplomatic skills, which she might have learned from observing her father. Her calming presence and ability to see different perspectives would help in resolving conflicts.
He could play the role of a master strategist. Thrawn's ability to analyze his opponents and predict their moves would make him a valuable asset to any side in the 'Game of Thrones' power struggles. He could be the one to turn the tides in battles and sieges.
She could be a healer. With her knowledge of medical ninjutsu, she could save many lives in the war - torn Westeros. This would make her a valuable asset to any side she chooses to support.
Wolverine might be a disruptor in the Game of Thrones world. He doesn't follow the same rules as the Westerosi. His presence could change the way battles are fought. For example, in a large - scale battle like the Battle of the Bastards, his individual combat skills could turn the tide. He could cut through enemy lines with his claws and inspire the troops he's fighting alongside. He might also be a voice of reason among the power - hungry lords, as he has his own sense of right and wrong that is different from the political games in Westeros.
It can also be a place of magic and mystery. In many fanfictions, the Godswoods are the source of strange and powerful forces. Writers might create new creatures or powers that are linked to the ancient trees and the old gods worshiped there. For example, there could be a magical well in the Godswoods that has the power to heal any wound, but only if the person is pure of heart. This adds an element of fantasy and intrigue to the already rich world of Game of Thrones.
