One great 'Game of Thrones Robb Stark OC fanfiction' is 'The Stark Heir'. It follows an original character who becomes an important ally to Robb Stark. The story has great character development and exciting battle scenes.
I recommend 'Robb Stark: The Lost Legacy'. This fanfiction focuses on an alternate timeline where Robb survives. It's interesting as it explores how he would have changed the course of the story. It has some great character development and interactions with other key characters from the series.
The relationship between Robb and Talisa in fanfiction can also be a source of great emotional drama. Their love could be tested by war, betrayal, and family obligations. Fanwriters might write about their private moments of joy and sorrow, how they comforted each other during difficult times, and how their love endured or, in some cases, tragically ended.
First, do your research on Robb Stark's character. Know his traits, his goals, and his relationships in the original series. Then, create your original character with a clear backstory, personality, and motivation. Make sure the OC's story can fit into the world of Game of Thrones. For example, if your OC is a warrior, think about where they learned their skills and why they would side with Robb Stark.
Another reason is that Robb Stark's story ended tragically in the original series. Fans are drawn to fanfiction as a way to rewrite his story, give him a better ending, or just see different interpretations of his character. It allows for a lot of creativity and speculation among fans.
One possible plot could be that Robb Stark manages to avoid the Red Wedding trap. Maybe he receives a tip - off from an unexpected source, like a disgruntled Frey servant. With this knowledge, he could turn the tables on his enemies. He might use his military strategy skills to ambush the Freys instead, and this could lead to a major shift in the power dynamics in the North, with Robb emerging as an even stronger leader.
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 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.
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.
It could change it a great deal. In the original story, Robb's actions regarding the Freys led to the Red Wedding. But if he married a Frey, it would mean no Red Wedding. This would keep Robb alive and his army intact. It could also change the power dynamics in Westeros as the Stark - Frey alliance would be very strong.
