One idea could be a crossover where the vampires from 'Vampire Diaries' find themselves in the political intrigue of 'Game of Thrones'. Maybe Damon Salvatore tries to charm his way through the courts of King's Landing, causing all sorts of chaos as his vampire nature is revealed bit by bit. Another plot could involve the White Walkers being related to some ancient vampire curse in the 'Vampire Diaries' lore, and the characters from both universes have to team up to stop the impending doom.
A possible plot for this fanfiction is that Elena Gilbert is transported to Westeros. She has to use her knowledge of the supernatural from Mystic Falls to survive in the cut - throat world of 'Game of Thrones'. She might form an alliance with Daenerys Targaryen, with Elena's ability to resist compulsion being seen as a form of magic in Westeros. Their combined forces could then take on common enemies, like the Lannisters who see them as a threat to their power.
One plot idea could be that Naruto is somehow transported to the Vampire Diaries world. He teams up with the Salvatore brothers to fight a common enemy, like a powerful vampire - witch hybrid that is causing chaos in the town. Naruto uses his ninja techniques, like shadow clones, to confuse the enemy, while the Salvatores use their vampire strength and charm.
One idea could be being reborn as a long - lost relative of the Salvatore brothers. Maybe you have some hidden power that was lost in the family history and now you have to navigate the vampire - filled world of Mystic Falls while trying to figure out your new abilities. Another plot could involve being reborn as a witch in the fanfiction world. You could use your magic to either help or hinder the vampires and other supernatural beings in town. You might also be reborn as a human with a special gift of seeing the future, which would put you in a dangerous position as everyone in the Vampire Diaries world would want to use your power for their own ends.
One idea could be being reborn as a long - lost relative of one of the main characters. For example, a long - lost sister of Elena. This could stir up a whole new dynamic in the Mystic Falls gang. You could bring in new powers or a different perspective on the vampire - werewolf - witch drama.
One idea could be exploring what would happen if a minor character like Gendry had been secretly trained in magic. He could use his newfound powers to unite the smallfolk against the warring nobles. Another plot could revolve around a female knight from the North who disguises herself as a man to fight in the wars, and along the way, she discovers secrets about the White Walkers that no one else knows. Or perhaps a fanfiction where Daenerys and Sansa form an alliance much earlier and together they reshape the power dynamics of Westeros.
One common theme is survival. In Vampire Diaries, the vampires and other supernatural beings are constantly in a fight for survival, and this is often explored more deeply in fanfiction. In Game of Thrones, with all the wars and political intrigue, survival is also a key theme. Also, family loyalty is a theme. In Vampire Diaries, the Salvatore brothers' loyalty to each other is a big part of fanfiction, and in Game of Thrones, the loyalty within the houses like the Starks is often written about.
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.
Perhaps a story where a character discovers a long - forgotten magic that has been dormant since the very beginning of the vampire lore in this universe. This magic could be the key to solving a major problem like a new, more powerful type of enemy that is threatening both the vampires and the humans in Mystic Falls. The character then has to embark on a journey to fully understand and master this magic.
One idea could be a story where Elena discovers a long - lost relative who is also a powerful vampire hunter. This relative tries to turn Elena against her vampire friends, creating a lot of internal conflict for her.
