The powers of the X - Men would have a huge impact. For instance, Jean Grey's telekinetic and telepathic powers. She could easily manipulate the minds of the lords and ladies, making them vote or act in a certain way. This would completely disrupt the normal political intrigue and power plays that are based on alliances and manipulation through words and gold. It could lead to a new form of rule where those with the most powerful mutants are in control.
Their union would likely cause a great deal of upheaval. Many of the existing power players would see them as a threat. For example, the Lannisters might feel even more threatened by Tyrion's newfound power through his marriage to Daenerys. It could also lead to new alliances forming as other houses try to either side with them or oppose them.
Well, Naruto's immortality would give him an edge in the X - Men universe. His ninja skills like shadow clones could be used in really creative ways during battles. For example, he could send out clones to distract enemies while the real Naruto sneaks up on them. Also, his chakra powers might be seen as a new form of energy in the X - Men world, and some mutants might be curious or even afraid of it.
If Sansa gives birth, it could solidify her claim to power in the North. A new heir means a continuation of her line, which would make it harder for any rival houses to try and usurp her position. Other regions might also view her differently. For instance, the Vale which has been an ally might become even more closely tied to the North. They could see the new heir as a way to further their own influence in the future of Westeros through marriage alliances.
The Lich King could be a major disruptor. He doesn't care about the normal politics of the Iron Throne or the houses. He would likely try to use the political chaos to his advantage. For example, he could support one side in a war just to create more death and destruction, which he can then use to raise more undead soldiers.
Well, imagine Storm in the world of Game of Thrones. Her ability to control the weather would make her a very powerful force, perhaps seen as a goddess by some in the superstitious Westeros. She could play a role similar to Melisandre, but with a more benevolent nature. Cyclops, on the other hand, with his powerful optic blasts, would be like a one - man army. He might be recruited by one of the kings or queens to fight in their wars, but his sense of justice would likely put him at odds with the more cut - throat political players in the Game of Thrones universe.
The plot could involve the X - Men being transported to the world of Westeros. They would initially be confused by the different rules and power dynamics. But soon they would realize that there are threats here too, like the White Walkers. They could team up with some of the more honorable characters in Game of Thrones, like Jon Snow, to fight against the common enemy. Meanwhile, some of the power - hungry characters in Westeros might see the X - Men as a new source of power to be exploited.
One interesting crossover could be the X - Men characters in the world of Westeros. For example, Magneto could use his powers to manipulate the iron in the weapons and armors of the various factions in Game of Thrones. He might side with a particular house, perhaps seeing an opportunity to gain power or protect mutants in this new and different world. Wolverine's healing factor and combat skills would make him a formidable fighter in the battles of Westeros. He could find himself involved in the power struggles, similar to how he gets involved in various conflicts in the X - Men universe.
If the X - Men were in the Frozen universe, they would bring a new dynamic. Wolverine's healing factor would make him a valuable asset in the cold and dangerous environment. He could withstand extreme cold and any injuries that might come from the ice. Storm could collaborate with Elsa to create more elaborate weather patterns. The X - Men's mutant status could also cause some interesting reactions among the people of Arendelle, who are not used to such extraordinary abilities. It could lead to a story about acceptance and cooperation between two very different groups.
Well, in many of these fanfictions, it can create a lot of shockwaves within the X - Men. Their relationship has always been a bit of a power struggle. If they share a kiss, it could lead to divided loyalties among the team members. Some might side with Wolverine, some with Cyclops, depending on their previous allegiances.
His powers could also be used for reconnaissance. Quicksilver could zip around and gather intel on Ultron's lair or his next move. This information would be crucial for the X - Men and the Avengers to plan their counter - attacks. He might find out about new types of Ultron drones being developed or a hidden weapon that Ultron plans to use against them.
