An OC who is a skilled assassin would be a good choice. They are hired to kill someone in King's Landing but cross paths with Cersei. Cersei, instead of having the OC killed, decides to use their skills for her own purposes. The assassin has their own code and ethics, which would constantly be at odds with Cersei's methods.
One idea could be that the OC is a healer from a far - off land who comes to King's Landing. Cersei initially distrusts the OC but as time passes, she realizes the OC's skills are invaluable, especially when it comes to treating her children's ailments. This could lead to a complex relationship where Cersei struggles between her pride and her need for the OC.
Sansa Stark could be an interesting pairing. It could be a story of two strong - willed women from opposing sides. They could either become bitter enemies or, in a more creative take, find common ground and form an unexpected alliance. Also, Margaery Tyrell is a great character to pair with Cersei. Their power struggle in the show was fascinating, and fanfiction could take it in new directions, like Margaery actually befriending Cersei and showing her a different way to rule.
Yes, there are quite a few out there. Some focus on how Cersei's pregnancy would change her power dynamics in King's Landing. For example, in some fanfictions, her pregnancy makes her more vulnerable to political attacks as her enemies see an opportunity to undermine her while she is in a physically weaker state due to pregnancy. However, the quality of these fanfictions can vary greatly.
Some of the more independent lords or ladies in Westeros could be allies. For instance, Lady Brienne of Tarth. She is a paragon of honor and if the bastard displays honorable intentions, she could offer her sword and protection. Also, the wildlings might see the bastard as a way to gain some influence in the south. If the bastard offers them something in return, like a place to settle or resources, they could form an alliance.
There's also a possibility of her allying with some of the more neutral houses. Houses that were tired of the constant fighting between the big players. Her daughter could offer them stability and protection in exchange for their loyalty. She could present herself as a new hope for a more peaceful Westeros, which might attract these houses to her side.
He could influence events by being a voice of reason in Cersei's court. If he's intelligent and perceptive, he might be able to persuade his mother to make more diplomatic decisions rather than always resorting to force.
In Cersei Lannister x OC fanfiction, the character dynamics can be very interesting. Cersei is a complex character with her own motives and desires. When paired with an Original Character (OC), it allows for new storylines. For example, the OC could be someone who challenges Cersei's power-hungry nature or perhaps becomes an unexpected ally. Their interactions might lead to power struggles, emotional turmoil, or even a strange sort of friendship. The key is how the author develops their relationship in the context of the 'Game of Thrones' universe.
Well, there would obviously be the bastards themselves. They could be given names like Joffrey Jr. (even if it's just a fan - given name), a son who has all of Cersei's cunning and a thirst for power. Then there could be a daughter named Myrcella - like, after the real Myrcella but with a different personality. She might be more fierce and independent, not willing to be a pawn in the political games like the original Myrcella.
Cersei herself is often well - written in fanfiction. Writers can explore her complex personality further, showing her vulnerability behind her cold and calculating exterior. They can also expand on her relationship with her children in ways that the show might not have fully explored.
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.
