A plot idea could be that a powerful Pokemon is discovered in Westeros and all the houses start to fight over it, believing it will give them an edge in the war for the Iron Throne. This Pokemon could have abilities that are crucial for ruling, like mind - control or the power to create unlimited resources. Another idea is that a Pokemon trainer from the Pokemon world gets lost in Westeros and has to use their Pokemon skills and knowledge to survive the political and violent environment. They might form alliances with certain houses by offering the use of their Pokemon in battles.
Here's a plot idea. In the world of Pokemon, there are ancient legends about a parallel world similar to Westeros. A group of Pokemon trainers, led by an experienced trainer, manage to open a portal to this world. Once in Westeros, they find that the people there are in awe of their Pokemon. But they also get caught up in the power struggles. The trainers have to decide whether to side with certain houses or try to stay neutral. Meanwhile, some of the houses start to see the Pokemon as a new form of military might and try to capture and train them for their own purposes. This leads to a complex web of relationships and conflicts between the Pokemon trainers and the people of Westeros.
A really cool 'Game of Thrones fanfiction' plot could involve the resurrection of some of the dead characters in a different way. For example, what if Ned Stark was brought back not as a vengeful wraith but as a wise advisor to a new king or queen? His honor and wisdom could shape the future of Westeros in a completely new direction. And it would be interesting to see how the other characters react to his return.
Perhaps a fanfiction where Daenerys Targaryen lands in Westeros earlier and forms an alliance with the Starks before the events of the main series. This would completely shift the political landscape and the fight for the Iron Throne. She could bring her dragons to help fight the White Walkers from the start.
One idea could be exploring what would happen if a minor character, like Gendry, had a more central role in the fight against the White Walkers. He could lead a group of common folk and prove that the power doesn't always lie with the nobles.
A really interesting plot would be if the Night King from Game of Thrones was actually a dark bender from the Avatar world who was banished there long ago. And the only way to defeat him is for the Avatar to travel to Westeros and use all four elements against him. Along the way, the Avatar has to deal with the different kingdoms and their power struggles, just like in the original Game of Thrones story. This would bring in a whole new dynamic of having an outsider with strange powers trying to save a world that is foreign to them.
One idea could be reincarnating as a minor character, like a servant in King's Landing. You could use your modern knowledge to avoid the chaos of the city and slowly rise in power by befriending key players. Maybe you know of some herbal remedies that could save a noble from a deadly illness and gain their favor.
One idea could be a story where the Starks form an unexpected alliance with the Greyjoys to take on the Lannisters. They could use the Iron Islands' naval power and the Stark's knowledge of the North's terrain to launch surprise attacks.
One interesting plot idea could be a character who was thought to be dead actually surviving and secretly plotting revenge. For example, a minor character who was presumed killed in a battle but managed to escape and now is working with an unexpected ally to change the power dynamics in Westeros.
A cool plot might be an avatar from a different world being brought into the Game of Thrones world and having to adapt to its politics and power struggles. This avatar could have unique abilities that make them a valuable asset or a feared enemy. For example, they could have the ability to read minds, which would give them an edge in the cut - throat world of Westerosi politics. They could either side with a noble house or try to create their own power base.
One idea could be a modern-day person transmigrating into a minor character in Westeros and using their knowledge of the future to gain power. For example, they might introduce new fighting techniques or diplomatic strategies.
Well, for a genderbend fanfiction, you could have a genderbent Tyrion. As a female, she might face even more discrimination due to her appearance and dwarfism in a society that values beauty in women. Her intelligence would still be her greatest asset, but she would have to navigate different social norms. Also, think about a genderbent Brienne. As a male, he might not face the same level of ridicule for his looks and his pursuit of chivalry could be seen in a different light. He could be more easily accepted in male - only orders or groups. And a genderbent Sansa could be interesting. As a male, he would have different opportunities and challenges in the political game of Westeros. Instead of being used as a pawn in marriages, he might be the one making strategic marriage alliances for power.
