In 'Game of Thrones Crossover Fanfiction', a cool concept would be crossing it with 'Alice in Wonderland'. Alice could wander into Westeros and disrupt the power balance with her strange and magical ways. Another idea is to cross it with 'The Hunger Games'.

And a crossover with 'Supernatural' where the Winchester brothers hunt down the supernatural threats in Westeros.

Well, for a 'a game of thrones crossover fanfiction', a crossover with 'Star Wars' would be cool. Picture the Nights Watch using lightsabers to fight the White Walkers. Or a crossover with 'The Matrix'. What if characters from Game of Thrones were trapped in the Matrix? Also, a crossover with 'Sherlock Holmes'. The detective skills of Sherlock could be used to solve the mysteries in Westeros.

One idea could be that the Night King from 'Game of Thrones' somehow travels to Middle - earth. There, he might team up with the forces of Sauron, creating a double threat to the free peoples. The characters from both universes would have to find a way to work together, like Arya Stark using her skills to infiltrate Sauron's ranks while Legolas and Jon Snow lead the combined forces in battle.

One idea could be a fanfic that focuses on the backstory of a minor character, like Gendry. Explore his life before he met Arya, how he survived on his own in King's Landing, and his early days as an apprentice to the blacksmith. Another could be a story set in a different part of Westeros during the events of the main series, perhaps in Dorne, and show how the political unrest there affected the common people. A third idea would be to create a fanfic where the White Walkers are not the main villains, but instead there is a new, more insidious threat emerging from within the Seven Kingdoms itself.

One idea could be to write a fanfic about a character who was thought to be dead but actually survived and is secretly plotting revenge. For example, a Stark family member who everyone believed perished in the Red Wedding.

One idea could be to explore the backstories of minor characters in Yi Ti. For example, a young servant in a noble house who has dreams of rising above his station. He could get involved in political intrigues that mirror the larger power struggles in Westeros.

In a Halo - Game of Thrones crossover fanfiction, the Forerunners' technology could be a huge factor. What if some of the Forerunner artifacts ended up in Westeros? Different houses might try to claim them, thinking they hold great power. The characters in Game of Thrones would be in awe of the advanced technology, and there could be a race to unlock the secrets of these artifacts, all while the political drama and power plays of Westeros continue.

One idea could be a scenario where the Vikings' raiding parties encounter the Night's Watch from Game of Thrones. Maybe they initially see each other as threats, but then realize they could be useful allies against the White Walkers. Another could be a story about a character from Vikings, like Ragnar Lothbrok, being magically transported to Westeros and having to navigate the complex politics there, similar to how he did in his own land.

One idea could be a character from 'Dishonored' getting transported to the world of 'Game of Thrones'. Maybe Corvo could use his powers to navigate the dangerous political landscape of Westeros. He could use his blink ability to quickly move through the Red Keep, unseen by guards, and gather information that could change the balance of power among the houses.

One idea could be exploring the breeding of dragons in a different way. Maybe a fanfic where characters try to breed dragons with unique traits by using magical or scientific means in the 'Game of Thrones' world. Another could be about the breeding of horses with special abilities for the knights to ride into battle. For example, horses that are faster or more resistant to the cold of the North.
