Well, at the beginning of 'Game of Thrones', the King of Westeros is Robert Baratheon. He came to power after the Rebellion against the Targaryens. He was a bit of a hedonist, liked his wine and women a great deal. His claim to the throne was through his distant Targaryen bloodline on his mother's side. He was a big, strong man in his youth but had let himself go a bit by the start of the story, which was part of his downfall in a way.
At the start of 'Game of Thrones', the King was Robert Baratheon. He had won the throne through war, defeating the Targaryens. However, his court was full of political intrigue. His relationship with his queen, Cersei, was strained as she had her own Lannister family interests. Also, he was in debt to the Lannisters which gave them a lot of influence over him. His excessive drinking and womanizing were starting to take a toll on his health and his ability to rule effectively.
Percy would need to be smart. He could survive by aligning himself with a powerful house. For instance, if he were to pledge his loyalty to House Stark, he would gain protection. The Starks are known for their honor, and Percy could contribute his own skills, like his intelligence in managing resources or his ability to read people.
In a Game of Thrones fanfiction involving Ashura and Indra, they could be part of a prophecy. Indra could be seen as the one who has the knowledge to decipher ancient texts that point to a great threat coming to Westeros. Ashura, on the other hand, with his great strength, would be the one to lead the fight against this threat. They would face challenges from the Lannisters who see them as a threat to their power.
In a fanfiction scenario, Hulk could be a creation of the Children of the Forest. Long ago, they used their magic to create a being of great strength to protect them from the First Men. But as time passed, he was forgotten and buried. Then, with all the magic resurfacing in Westeros during the events of the series, Hulk is awakened. His presence would completely disrupt the power balance, as he doesn't care about the Iron Throne or the politics of the land, but just reacts to threats and challenges in his own brute - force way.
Achilles would be an out - of - place yet fascinating addition to the Game of Thrones universe. Given his near - invincibility in battle, he could potentially change the balance of power. For example, if he fought for the Unsullied, they would become an even more terrifying military force. However, his sense of honor and heroism might clash with the more cut - throat politics of Westeros.
If Arya gets pregnant in a fanfic set in Westeros, it would be quite a shock. However, it could fit in if it was part of some grander scheme. Maybe she was used as a pawn by an enemy, and the pregnancy was a way to control her or her family. Or perhaps it was a result of a brief moment of weakness during her travels, and now she has to deal with the consequences in a world that isn't very forgiving towards women in such situations.
Well, Aragorn is from a very different fictional universe than Game of Thrones. But if in a fanfic, he might bring his elvish connections which could be a huge advantage in the power - hungry world of Westeros. He could form alliances with the more honorable houses like the Tullys perhaps, based on his own code of ethics. And his experience in battles against great evils would give him an edge in the many wars that plague Westeros.
Kylo Ren's character is complex. In a Game of Thrones fanfiction, his Force abilities would be like a very rare and powerful magic in Westeros. He could be a feared figure, perhaps seen as a dark sorcerer. His internal struggle between the light and dark side could be translated into a struggle for power in the cut - throat world of Westeros. He might start as an outsider but quickly rise in power due to his unique skills, much like how some characters in Game of Thrones gain power unexpectedly.
If Wonder Woman were in a Game of Thrones fanfiction, she would bring a different dynamic to the power struggles. She has a strong sense of justice and equality. In Westeros, where power is often misused and the weak are oppressed, she could become a symbol of hope. Her abilities like flight and super speed would give her an edge in combat and in traveling across the vast lands of Westeros. She could also interact with the various magical elements in the world, such as the White Walkers, in unique ways.
