A great plot twist could be that Daenerys Targaryen's dragons are not what they seem. Instead of being the powerful weapons she thought, they are actually the keys to awakening an ancient evil that has been sleeping beneath Westeros. This would put Daenerys in a difficult position, as she would have to decide whether to keep her dragons or try to find a way to stop the evil they are about to unleash.
Perhaps a character who was thought to be dead suddenly returns with new powers. For example, if Ned Stark came back as a warg, able to control animals and use that to his advantage in the power struggles of Westeros. It would completely change the dynamics as the other characters would have to deal with his unexpected resurrection and new abilities.
One interesting plot twist could be that the White Walkers and the humans form an alliance. In this fanfiction, it might start with a small encounter where a White Walker spares a human's life. As the story progresses, they realize they have a common enemy in a new, even more powerful and evil force emerging from the far east of Essos. This would force characters on both sides to reevaluate their beliefs and allegiances.
