What could be an interesting plot for an Iron Man and Game of Thrones crossover fanfiction?

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.

One possible plot could be that the Winchesters from Supernatural end up in the world of Game of Thrones. They could be on a hunt for a demon that has somehow found its way into Westeros. Maybe this demon is influencing the actions of some of the power - hungry lords, like Littlefinger. The Winchesters would have to navigate the complex politics of the Seven Kingdoms while also trying to figure out how to exorcise the demon without getting caught up in the wars for the Iron Throne.

Perhaps Bella could be a key figure in a crossover. She could be a 'dragon rider' in a sense, using her connection with Edward (similar to the bond between a dragon and its rider in Game of Thrones). Her immunity to vampire powers could translate to some sort of immunity to the dark magic in Westeros. The werewolves from Twilight could be allies with the Stark direwolves, and together they fight against common enemies, like an army of the dead led by a Volturi - like figure.

Definitely Tyrion Lannister. Tyrion is known for his intelligence and sharp wit. Iron Man, with his technological genius, would have some great exchanges with Tyrion. They could both come up with clever plans and strategies. Maybe they'd work together to outwit their enemies, whether it's the other power - hungry houses in Westeros or some new threat that emerges.

One possible plot could be that Iron Man's technology somehow gets transported to the wizarding world. Harry Potter and his friends are intrigued by this strange new technology. Iron Man, on the other hand, is baffled by magic. They have to work together to stop a threat that combines dark magic and advanced technology. Maybe Voldemort gets his hands on some Stark Industries weapons and they need Iron Man's expertise to disarm them while Harry uses magic to counter Voldemort's spells.

One possible plot could be Merlin, with his magic, finding himself in the world of Game of Thrones. He might use his powers to try and influence the power struggles. For example, he could help Daenerys control her dragons better or assist Jon Snow in his fight against the White Walkers. Maybe he would be seen as a sorcerer from a far - off land and have to prove himself to the different factions in Westeros.

Imagine Iron Man arriving in Westeros during the White Walker invasion. His repulsor rays and energy shields could be extremely effective against the undead. He could also use his technology to communicate over long distances and coordinate the defense of the Seven Kingdoms. His presence would surely disrupt the existing political and military order in the Game of Thrones world.

A cool plot could be that the Justice League discovers a strange energy signature that turns out to be Iron Man's arc reactor. They track it down and find Iron Man. Iron Man is initially out of his depth in this new world of superpowers. But he uses his wits and technology. For example, he could upgrade the Flash's suit to make him even faster, and in return, the Flash helps him understand the new world he's in. Together, they all face off against Darkseid who has plans to invade both universes.

One unique feature is the clash of different universes. Iron Man's high - tech world meets the medieval, magic - filled world of 'Game of Thrones'. It creates a lot of possibilities for new storylines.
