One idea could be a story where Kratos finds himself in the world of Westeros. Maybe he gets involved in the power struggles between the houses. He could use his combat skills to fight against the White Walkers, bringing a whole new level of action to the fight against the undead.
Another possibility is that a character from Game of Thrones, like Jon Snow, somehow travels to the realm of God of War. He might learn from Kratos about different forms of combat and magic, and then bring those skills back to Westeros to help in the fight against his enemies. This could lead to some interesting crossovers in terms of weaponry and fighting styles.
One idea could be a character who has the power of the Tailed Beasts from Naruto and uses it in the political intrigue of Westeros in 'Game of Thrones'. For example, they could use the power of the Nine - Tails to intimidate their enemies during a battle for the Iron Throne.
A 'God of War' and 'Game of Thrones' fanfiction might feature a crossover of their mythologies. The gods in 'God of War' could interact with the Seven in Westeros. For example, Zeus could have some sort of encounter with the High Sparrow. Kratos might also have a unique perspective on the power struggles in the Seven Kingdoms, having dealt with his own power - hungry gods in his world.
One idea could be to have Percy Jackson transported to the world of Game of Thrones. Maybe he arrives in Westeros and is mistaken for a powerful sorcerer because of his demigod powers. He could get involved in the power struggles between the different houses, using his skills in combat and his ability to control water to his advantage.
A third idea is to create a fanfiction where the backstories of the RWBY characters are intertwined with the lore of God of War. For instance, Weiss could have a connection to a long - lost civilization in the God of War world that was known for its ice - based magic. This discovery could lead her on a journey to uncover her family's past and also learn more about this new world she's connected to.
One idea could be to create a story where the ninjas from Naruto are inserted into the political intrigue of Westeros. For example, Naruto, with his strong sense of justice, could find himself in the middle of the power struggle for the Iron Throne. He might try to use his ninja skills to bring peace to the war - torn land, much like he did in the Hidden Leaf Village.
Another approach could be to merge the magic systems. In Dark Souls, there are different types of magic like pyromancy and sorcery. Imagine if these were introduced into the Game of Thrones world. Maybe a pyromancer could influence the outcome of battles in Westeros in a new and unexpected way, or a sorcerer could use their illusions to deceive the power - hungry lords and ladies.
In a 'God Naruto Game of Thrones' fanfiction, Naruto's character would bring a whole new dynamic. His journey to become Hokage in his own world has made him strong - willed and determined. In the Game of Thrones setting, he might view the Iron Throne as something similar to being Hokage. However, the complex web of relationships and betrayals in Westeros would be a huge challenge for him. He'd have to navigate through the schemes of Cersei, Littlefinger, and others while also dealing with the threat of the White Walkers if the story takes place during that time period.
One idea could be to have Kratos end up in the world of Westeros. He might be mistaken for a powerful warrior from a far - off land. Maybe he gets involved in the power struggles between the different houses, using his combat skills to either help or hinder certain factions. He could also encounter some of the magical creatures in the ASOIAF world, like the White Walkers, and his god - slaying abilities would surely make for an interesting showdown.
One idea could be a story where the political intrigue of the Roman Senate is mirrored in the power struggles of the Great Houses in Westeros. For example, the patrician families in Rome could be compared to the noble houses in Game of Thrones, with similar backstabbing and alliances for power.
In such a fanfiction, perhaps the concept of the Sharingan in Naruto could be related to some sort of immortality in the Game of Thrones universe. Characters with the Sharingan could see the future and avoid death, like they do in Naruto. They could then use this ability to manipulate the events in the Seven Kingdoms. They might side with different houses based on their own goals, all while trying to keep their immortality - related secret safe from those who would do them harm.
