He could be an outsider who comes in and disrupts the normal flow of things. Maybe he arrives through some sort of magical portal. He'd then have to figure out the political landscape. He might first ally with the smartest characters like Tyrion, seeing potential in his intellect. And with his knowledge of advanced warfare, he could change the way battles are fought in Westeros.
Tony Stark would likely find himself in the middle of the power struggles. He could use his wealth (in whatever form that would take in Westeros) to buy influence. His engineering skills could be used to improve the defenses of a city, say King's Landing. He'd also be a target for those who fear change, like the Sparrows. But he'd use his charisma to try and win over the common people, much like he did with the public in the Marvel movies.
He might be adapted as a sort of foreign nobleman with strange powers. His Iron Man suit could be seen as a magical armor. He'd bring his sense of humor and quick - wittedness to the courtly intrigues of Westeros.
Imagine Tony Stark in Game of Thrones. He'd probably first be seen as a sorcerer or some sort of otherworldly being because of his high - tech gadgets. He could potentially form an alliance with Daenerys, offering her his technological prowess in exchange for her dragons. His presence would disrupt the traditional magic and warfare in the series. His suit could be a game - changer in battles against the White Walkers. And his sarcastic and confident personality would make for some great dialogues with the various characters in the GoT universe.
Tony Stark in a Star Wars fanfic might be a sort of outsider who brings new ideas. He could team up with some of the Jedi or the Rebels. He'd probably be really interested in the Force, trying to understand it from a scientific perspective. And he'd surely use his engineering skills to upgrade starships or build new defense systems for the good guys.
Well, he'd probably try to use his technology to outwit the political schemes in Westeros. Maybe he'd create some sort of high - tech armor to protect himself from the swords and arrows. He could also use his intelligence to manipulate the power struggles, like he did in the MCU.
Well, they could be new characters introduced in a small northern village. Maybe Ros, being a kind - hearted person, could help Daisy (the OC) who is lost and trying to find her way in the harsh world of Westeros. They could get involved with the Starks somehow, perhaps by providing some crucial information during a battle.
A 1930s 'Game of Thrones' fanfic would transform the storyline in multiple ways. Firstly, the role of women would be different. In the 1930s, there were women starting to break out of traditional roles. So, female characters in 'Game of Thrones' like Arya or Sansa might have more opportunities to be independent and fight for their own causes. Secondly, the concept of war would change. With the new military technologies of the 1930s, battles would be more mechanized. This would also affect how different houses strategize and fight for power. Also, the religious aspect would be different. The old gods and the new god might be less relevant, and new ideologies might emerge as a replacement, much like how new political and social ideologies emerged in the 1930s real - world.
One cool plot could be that Tony Stark is transported to Westeros right before the onset of the Long Night. He teams up with Bran Stark, using his technology to help Bran better understand the visions he has of the past and future. Stark also uses his suit to fight the White Walkers, creating a new type of weapon against the ice - based enemies. His presence also causes a stir among the various houses, who either want to use his power for their own gain or see him as a threat.
In a fanfic, Wonder Woman would be a game - changer in the politics of Game of Thrones. Her presence alone would make the power - hungry lords and ladies think twice. She could use her influence to promote peace treaties, as she believes in resolving conflicts without unnecessary bloodshed. And she would not tolerate the abuse of power, like Joffrey's tyrannical rule. She would be a symbol of hope for the common people who are often the victims of the political games in Westeros.
Aquaman could be a very powerful force. He has his own set of powers like super strength underwater and the ability to communicate with sea creatures. In the power dynamics of Game of Thrones, he could side with a particular house and give them an edge in naval battles. For example, if he sided with House Stark, he could prevent the Lannisters from getting supplies by sea.
He could fit in as a hero. For example, he might help Arya Stark in her quest for revenge. His combat skills and ability to strategize would be very useful to her. He could also protect the innocent villagers from the raids of the various warring factions.
