In a fanfiction, the Hulk could form an unexpected alliance. For instance, he might team up with Tyrion Lannister. Tyrion is used to being an outcast, and he could see the potential in the Hulk. They could both be a force against the more tyrannical rulers. And the Hulk's raw power combined with Tyrion's wits could make for a very interesting duo.
The dynamic between the Hulk and the dragons would be fascinating. Dragons are the most powerful creatures in Game of Thrones, but the Hulk has his own kind of indomitable strength. They could be rivals, or in some cases, they might end up working together. Maybe the Hulk could ride a dragon in some wild turn of events, creating a truly unique and powerful combination in the world of Westeros.
The Hulk would probably have a very different dynamic with the various characters. With the more honorable characters like Ned Stark, they might initially be cautious but then try to reason with the Hulk or at least figure out how to co - exist with him. However, with more power - hungry characters like Cersei, she might see the Hulk as a threat to her rule and try to eliminate him.
The Hulk might be seen as a sort of monster in the context of Game of Thrones. Just like how they have direwolves and dragons, the Hulk could be another mythical - but in this case, suddenly very real - creature. He could be shunned by some and perhaps worshipped as a god by others, depending on how different regions of Westeros react to his existence.
With Arya Stark, Achilles could be a mentor - like figure. Arya is on her journey to become a great fighter, and Achilles, with all his battle experience, could teach her new techniques and a different perspective on combat. However, their cultural differences, Achilles from Greek mythology and Arya from Westeros, could also create some interesting clashes and learning opportunities for both characters.
Hulk could be a protector of the Wall. Instead of the Night's Watch, he stands guard against the White Walkers. His strength would be a great asset against the undead hordes. He might not understand the politics of the Seven Kingdoms, but he knows when something is a threat. And the sight of a giant green monster fighting off the White Walkers would be an amazing addition to the Game of Thrones lore. He could also form an unlikely friendship with some of the members of the Night's Watch, like Jon Snow, who would respect his power and his simple sense of right and wrong.
Jaune Arc would likely be an outsider at first, but his unique skills could quickly make him a player in the power dynamics. If he has his combat abilities from his own world, he could become a valuable asset to a particular house or faction. His sense of honor and justice might also set him apart, as the Game of Thrones world is often filled with self - serving characters. This could attract followers, including women who see his potential for positive change, and thus start to form his harem within the power structure.
Daenerys in Winterfell would disrupt the existing power dynamics in multiple ways. For one, her very presence as a Targaryen with a claim to the throne challenges the Stark's authority in the North. Her dragons are a huge factor; they could be used to intimidate or be seen as a great asset. This might lead to some characters trying to manipulate her for their own gain. For example, Littlefinger (if he were still alive) might try to play both sides, using Daenerys against the Starks or vice versa. Also, the common people in Winterfell would be divided in their opinions of her, some seeing her as a savior and others as a foreign invader.
A professional army in a Game of Thrones fanfiction would change power dynamics in many ways. Firstly, their presence might make certain regions more stable if they are under the control of a just leader. However, it could also create more tension. Other kingdoms or factions might see this as a threat and start to build up their own forces or form coalitions against the one with the professional army. It could also influence the politics at court, as diplomats would have to consider this new military strength when making deals or treaties.
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.
Well, Kagome would be quite out of place at first in the Game of Thrones setting. But her adaptability would soon come into play. She might be initially shocked by the brutality and lack of honor in some of the characters' actions. However, she could use her intelligence to navigate the dangerous court politics. She could also introduce new concepts like respect for nature and spirits, which are not as prominent in the Westerosi culture. And if she had her shards of the Sacred Jewel, they could potentially have some strange and powerful effects in the Game of Thrones world.
He could be a wild card. Since he's the son of Drogo, the Dothraki would respect his lineage. He could potentially side with Daenerys if he sees her as a means to achieve his own goals, like bringing glory to the Dothraki name. Or he could oppose her if he thinks she's leading the Dothraki astray from their traditional ways.
For a 'Game of Thrones' fanfiction mercenary, consider Aeron. He's a former sellsword who has seen the horrors of war. Aeron is an archer with exceptional aim. He's a bit of a loner but is drawn to causes that seem just. He has a distrust of nobles after being double - crossed by one in the past, and his armor is a patchwork of different pieces he's collected over the years.
