Another plot might involve a main character like Jon Snow being mind - controlled. Imagine if he was made to fight against his own people. It would be a huge shock to the other characters and would completely change the direction of the story.
A 'Game of Thrones' mind - control fanfic can be really interesting. It often takes the complex world of Westeros and adds an extra layer of psychological drama. Some fanfics might explore how mind control could be used in the power struggles between the different houses. For example, a character like Littlefinger could potentially use mind control to further his own ambitions, manipulating lords and ladies to do his bidding.
One possible plot twist could be the introduction of gunpowder in a way that completely changes the power dynamics in Westeros. For example, if a small, previously unimportant house discovers a large stash of gunpowder and the knowledge to use it effectively. This could lead to them suddenly becoming a major player in the game of thrones, as they could use it to take over castles or defeat larger armies. Another twist might be if a character we thought was on one side is actually using gunpowder to secretly undermine their own faction for personal gain. Or perhaps a foreign power enters Westeros with advanced gunpowder weapons, forcing the local houses to adapt quickly or be wiped out.
A plot where Vikings raid the Iron Islands and form an alliance with Euron Greyjoy. They could then together plan to conquer the other kingdoms. The Vikings' seafaring skills combined with Euron's knowledge of Westeros would make for a very powerful force.
One of the most interesting relationships is between Daenerys Targaryen and her advisers. They form a sort of 'harem' of loyalty around her. Jorah Mormont, for example, is extremely loyal and his relationship with Daenerys is complex. He loves her in his own way, while also trying to guide her. Missandei is another important figure in her inner circle. Their bond is based on mutual respect and a shared goal of seeing Daenerys on the Iron Throne.
The reaction of the common people. In Game of Thrones, the common folk are often at the mercy of the nobles. Superman is a hero who stands for the common good. How would the common people of Westeros respond to him? Would they see him as a savior or just another powerful entity to fear? This could be a really engaging part of the fanfic.
Another intriguing crossover could be a love story between a 'Game of Thrones' character and Dracula. For instance, if a character like Sansa Stark, who has endured so much and grown strong, were to meet Dracula. It could be a story of her being both attracted to and repelled by his dark power. Or perhaps she tries to use his power to get revenge on her enemies. Their relationship could develop in complex ways as they come from very different worlds but share a thirst for power in different forms.
There could be a fanfic plot where a human scientist who has been living in Pandora for a long time discovers a way to enhance the connection between the Na'vi and their spirit trees. This causes a stir among the Na'vi as they are not sure if this new technology is a blessing or a curse. The story could explore the moral and ethical implications of this discovery.
One interesting plot twist could be the introduction of Ucbiha characters' unique powers into the Game of Thrones world. For example, if an Ucbiha character has the ability to control fire, it could change the power dynamics in Westeros, especially during battles or political struggles. Maybe they could form an alliance with Daenerys, adding a new element to her quest for the Iron Throne.
One of the most interesting plot twists could be a character who was thought to be a minor noble rising to a key power figure. Maybe they discover a long - lost heirloom that gives them some sort of magical or political advantage. For example, a small - time knight finds an ancient sword that was once used by a great conqueror. This sword gives him the respect of the people and he starts to amass an army.
Some fanfics might explore Nagini's connection to the other Horcruxes. Since she was the last Horcrux to be destroyed, perhaps there was some kind of communication or power exchange between her and the other Horcruxes that we didn't see in the books. This could add a whole new layer of mystery to the story.
