In this fanfiction, a great storyline could be that Naruto and Joramun are seen as prophets or saviors by a small group of people in Westeros who are tired of the constant war and power struggles. They try to spread their message of peace and cooperation, but are opposed by the major houses who see them as a threat to their power. As they journey through Westeros, they also discover secrets about the land that could change everything. Maybe there are ancient powers that Naruto's chakra can interact with, and Joramun has some knowledge about these from his own world. This would create a complex and exciting story full of twists and turns.
There could be a storyline where Naruto and Joramun form a sort of mercenary group in Westeros. They offer their services to the highest bidder, but they also have a code of ethics that they follow. This causes conflict when they are hired by a less - than - honorable house. Naruto's desire to do the right thing clashes with the expectations of his employer. Joramun, on the other hand, might be more practical and try to find a middle ground. This could lead to a split in their group and they would have to face the consequences, both in terms of the ire of the house they were working for and the power struggles in Westeros at large.
Well, if Naruto was in a Game of Thrones fanfic with Joramun, Naruto's ninja skills could give him an edge in the cut - throat world of Westeros. He could use his shadow clone jutsu to deceive his enemies, much like how characters in Game of Thrones use misinformation. Joramun, on the other hand, might bring in his own brand of leadership and knowledge of the North. Their combined forces could potentially change the power dynamics in Westeros, especially if they were to side with a particular house.
In a Naruto, Ghost Rider, High School DxD fanfiction, a great storyline could be that the High School DxD world is in danger of being destroyed by an ancient evil. Naruto and Ghost Rider are brought in as the last hope. Naruto uses his friendship - building skills to gather allies among the students and factions, while Ghost Rider uses his power to fight off the minions of the ancient evil. As they progress, they discover that there are secrets in this world related to their own powers, and they must unlock them to save the day.
One possibility could be the rebuilding of Westeros. After all the destruction and power struggles, the remaining kingdoms might focus on restoring their lands, economies, and populations. New leaders could emerge who are more interested in peace and cooperation rather than conquest.
One possible alternate storyline could be that Robert manages to uncover the truth about Cersei's infidelity earlier. This would lead to a major political upheaval in King's Landing. He might exile Cersei and her children, which would change the power dynamics completely. With no Lannister influence at court, Ned Stark might have more sway, and the events leading to the War of the Five Kings could be averted.
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.
The merging could happen with a common enemy. Suppose there's an alien - like threat that starts to invade Westeros. Master Chief, being a hero used to fighting off extraterrestrial foes, steps in to help. His military tactics and combat skills would be a huge asset. He could train the soldiers in Westeros in new forms of warfare, and in the process, he'd have to navigate the complex political and cultural landscape of the Seven Kingdoms.
Game of Thrones fanfiction featuring Howland Reed could have him solving long-standing riddles, influencing major battles, or even starting a new chapter in the history of the Seven Kingdoms. The possibilities are endless, depending on the author's imagination!
Some fanfictions focus on the backstories of minor characters. For example, a story about the life of a Night's Watch member before he joined. It could explore his reasons for joining, his family, and how he coped with the harsh life at the Wall. There are also fanfictions that rewrite the end of the series in a more satisfactory way for fans, like Jon Snow actually ruling the Seven Kingdoms in a more just and prosperous manner.
He could form some really interesting relationships. He might befriend the underdogs, like the Starks, and use his powers to help them. Or he could have a mentor - like relationship with someone like Tyrion, sharing his wisdom from his own world. He could also have an adversarial relationship with the more power - hungry characters, like Cersei, as his values would likely clash with hers.
It could be a wild mix. Imagine Naruto's ninjutsu in the world of Westeros. Maybe Naruto would be like a super - powered knight, using his shadow clones to fight off White Walkers. His chakra could be seen as a sort of magic in that world.
