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.
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.
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.
Hot Pie could be the unexpected hero. He might use his baking skills in an unexpected way. For instance, he creates a special type of bread that has some sort of magical property. This bread could be used to heal the wounded or even give the soldiers who eat it superhuman strength during a battle against a powerful enemy.
One interesting plot could be the mages from Fairy Tail being transported to the world of Game of Thrones. They might use their magic to deal with the political intrigue and battles there. For example, Natsu could use his fire magic to fight against the White Walkers, adding a new element to the fight against the undead.
Well, it could revolve around a particular event in the 'Game of Thrones' universe where someone uses their wits or skills just in time. Maybe it's a story about a character who seizes an opportunity at the right moment to gain power or save someone they care about. For example, a character might step in to stop a betrayal just before it's too late, similar to how a stitch in time saves nine in real - life situations. It could also be a more fantastical take, like using magic at a crucial moment.
The idea of Aslan taming the dragons is a fascinating plot point. Dragons are symbols of power in Game of Thrones, and Aslan's gentle yet powerful nature could potentially change the way the dragons are perceived and used in the story. For example, in some fanfictions, Aslan forms a bond with Drogon, which then leads to a series of events that change the power balance in Westeros.
A really interesting plot twist could be when Godzilla actually turns out to be a creation of the Three - Eyed Raven to fight the Night King. It completely changes the perception of Godzilla's role in the fanfiction.
In some 'Game of Thrones' Phoenix fanfiction, a common plot twist is that the phoenix has the ability to resurrect dead characters. This completely changes the course of the story as characters who were thought to be gone forever return. For example, in one fic, Ned Stark is brought back by the phoenix's magic, which then sets off a whole new chain of events as he tries to reclaim his honor and seek revenge on those who wronged him.
A plot where Deadpool somehow becomes a king would be really interesting. He'd probably run the kingdom in the most unorthodox way, making strange laws and having his own brand of 'justice'. For example, instead of beheading traitors, he might make them do stand - up comedy about their crimes.
One idea could be a new lord who is a long - lost heir to a powerful but fallen house. He starts from nothing, gathering a small group of loyal followers, some outcasts and misfits. He uses his wits and new - found knowledge of forgotten battle tactics to slowly rise in power. He might form an alliance with a group of local peasants who are tired of being oppressed by the existing lords. Through their combined efforts, they start to build a new, more just community which catches the attention of the greater powers in Westeros.
Imagine that the Tesseract accidentally opens a portal between the Marvel universe and Westeros. The Avengers come through and are immediately caught in the middle of the War of the Five Kings. Tony Stark might befriend Tyrion Lannister, both being intelligent and a bit of an outcast in their own worlds. Thor could find common ground with the Red Priests who worship the Lord of Light, as it has some similarities to his own beliefs. The Avengers would then have to choose sides in the war while also preparing for the greater threat of the Others, which they learn about from the Night's Watch.
One interesting plot could be that AOC (assuming it's a character from another source) somehow gets transported to the world of Game of Thrones. She could use her modern - day knowledge and ideals to try and change the political landscape. For example, she might introduce concepts of equality and democracy to the feudal system of Westeros, which would surely stir up a lot of conflict among the different houses and power - hungry individuals.
