Jon Snow is always a memorable character in Battle of the Bastards fanfiction. His leadership and determination are often central to the stories. He is the one leading the fight against Ramsay Bolton, and his actions and decisions drive the plot forward. Another is Ramsay Bolton himself. His cruelty and cunning make him a very interesting character. In fanfiction, his devious plans and his attempts to outwit Jon are often explored in more detail.
In some fanfictions, a plot twist might be that a long - lost relative of Jon Snow shows up during the Battle of the Bastards. This relative could have a powerful army or some unique ability that changes the course of the battle completely. For example, if it was a Targaryen relative who had a dragon egg that hatched during the battle. The sudden appearance of a dragon would completely disrupt the battle and give Jon's side an unexpected advantage.
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.
There are fanfictions where the characters react to alternate endings. In some, they might react to a world where Daenerys doesn't go mad. The characters' responses to this different turn of events can offer new perspectives on their personalities and relationships.
One interesting plotline could be a bastard of Robert's rising to power in a unexpected way. Maybe he uses his knowledge of the Baratheon family secrets to gain influence. For example, he could expose some hidden affairs or deals that the main families were involved in, which would shake the power dynamics in Westeros.
One possible plot idea could be that Cersei's bastards grow up in secret and form an alliance to take revenge on those who wronged their mother. They might use their wits and hidden identities to manipulate the power dynamics in King's Landing.
In the 'Battle of the North' in the 'Game of Thrones' fanfic, it often showcases the epic struggle for survival and power in the North. The North is a harsh and unforgiving place, and battles there are filled with brutal combat. Different factions fight for control, resources, and honor. It's a great setting for intense character development as characters face extreme challenges and moral dilemmas.
Some characters might be shocked. For example, Tyrion Lannister would probably find it both amusing and a bit offensive at times. He has a sharp wit and would likely make sarcastic remarks about the fanfic's portrayal of him.
