What are some interesting plot ideas for a 'Game of Thrones' OC time travel fanfic?

One idea could be Sansa traveling back to the very beginning of the series and using her knowledge to prevent Ned Stark's death. She could subtly manipulate events, like warning her father about Littlefinger's true nature. Another could be her going back to the time of the Mad King and trying to find a way to end his reign more peacefully, which would change the entire future of Westeros. Or perhaps she travels to a time during the War of the Five Kings and allies with different houses in a new way to secure the North's future.

One idea could be an original character who is a bastard from a minor noble house in the North. They grow up with a unique skill, like being an expert tracker. They could get involved in the events related to the White Walkers early on, perhaps by accidentally stumbling upon one of their lairs. Their journey could then be about warning the other houses and trying to find a way to stop the threat before it reaches the major kingdoms.

One interesting plot idea could be exploring what would happen if a minor character, like Gendry, had secretly been trained in magic all along. He could use his newfound powers to try and claim the Iron Throne in a different way than the main characters. Another idea is a fanfic set in the past, showing how the relationship between the Starks and the Lannisters first started to sour. Maybe a long - forgotten event that set the stage for all their future conflicts.

One plot idea could be an OC who is pregnant and trying to hide it from powerful enemies in King's Landing. She has to navigate the dangerous political intrigue while protecting her unborn child.

One idea could be an OC who is pregnant and is trying to hide it from the warring factions in King's Landing. She might be a servant in the Red Keep and is afraid of what will happen if her pregnancy is discovered, as she doesn't know who the father is among the many lords and knights who frequent the castle.

One idea could be an OC Baratheon who is a long - lost cousin. This OC could come to King's Landing with a claim to the throne, causing political unrest among the existing Baratheon claimants. He or she might have unique skills, like being an expert in naval warfare, which was important for the Baratheons. Another plot could involve an OC Baratheon woman who disguises herself as a man to fight in the wars, and along the way, she discovers secrets about her family's past that could change the course of the Baratheon legacy in Westeros.

Perhaps the OC Dragonlord is a bastard of a Targaryen. They grow up in Essos, learning the ways of dragon - taming from an old sorcerer. When they hear of the chaos in Westeros, they decide to cross the Narrow Sea with their dragon, planning to claim a throne for themselves. Along the way, they form an unlikely alliance with a group of outcasts, who help them navigate the political intrigues of Westeros.

A plot idea could involve the Direwolf OC being an outcast among its own kind. It then forms an alliance with a group of outcasts in Westeros, like a band of thieves or a small, forgotten clan. They all work together to change their fates. Another interesting plot would be if the Direwolf has the ability to communicate with other animals. It uses this power to gather information for its human companion, and they use this knowledge to outwit their enemies in the game of thrones. You could also have a plot where the Direwolf OC is the last of its kind and it's on a mission to find a way to repopulate its species.

Well, an interesting plot for a God OC in Game of Thrones fanfiction could be that the God OC is the true heir to the Iron Throne. This God OC has been hidden away for centuries and now returns to claim what is rightfully theirs. They have powers that no one has ever seen before, like the ability to transform into any creature. This could lead to some really cool battle scenes where the God OC takes on the form of a dragon to fight against the other claimants to the throne. They could also use their powers to unite the different kingdoms under their rule, but not without facing a lot of resistance from the power - hungry lords and ladies of Westeros.

Another interesting OC for a 'Game of Thrones' fanfic could be a sellsword from Essos who has a mysterious past. Maybe they were once part of a noble family but were exiled. Their journey in Westeros could involve getting involved with different factions, like the Brotherhood without Banners, and their skills with the sword could change the tides in small skirmishes.
