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.
A third concept could be to have the jutsu in Naruto replace the magic in Game of Thrones. The Sharingan could be seen as a rare and powerful form of 'magic' in Westeros. Characters like Sasuke, with his Sharingan, would be highly sought after or feared, similar to how those with powerful magic are in Game of Thrones.
Another possibility is to have the shinobi clans in Naruto be similar to the houses in Game of Thrones. So, the Uchiha clan could be like the Lannisters - powerful, with a dark side. And just as in Game of Thrones, there could be battles for supremacy between the different ninja clans, with alliances being made and broken.
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.
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.
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.
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.
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.
One idea could be that Naruto is transported to the Godzilla universe. He could use his ninja skills to try and communicate with Godzilla or other kaiju. Maybe he'd attempt to use his shadow clone jutsu to confuse the monsters during a battle.
One idea could be that Naruto characters are summoned as Servants in FGO. For example, Naruto himself could be a Berserker with his never - give - up attitude and powerful chakra being translated into high - level stats. Sasuke could be an Assassin, using his Sharingan to detect and strike enemies stealthily.
A more serious fanfic could be set in a post - apocalyptic world that was destroyed by a combined force of villains from both Naruto and Bleach universes. Naruto and Ichigo are the last hopes. They meet and initially clash due to their different ways of fighting and beliefs. But they gradually learn from each other and combine their powers in a unique way to take on the remaining villains and try to restore their worlds.
One idea could be that Venom somehow ends up in the Naruto universe. Maybe a strange rift in dimensions brings Venom to Konoha. He could initially be seen as a threat, but Naruto, with his ability to see the good in people (or in this case, symbiotes), tries to befriend Venom. This could lead to some really interesting battles and storylines, like Venom helping Naruto against powerful enemies using his unique powers.
A fanfic could be written where Alita is reincarnated in the Naruto universe as a ninja. She retains her combat skills but has to learn how to use chakra. Naruto becomes her friend and helps her adapt. They go on adventures together, facing off against powerful enemies. Alita's unique fighting style would make her stand out among the ninjas, and together they could become a formidable team.
