Well, there could be a story where Naruto lands on Earth and is mistaken for a superhero. People see his cool ninja moves and think he's some kind of new, amazing hero. He then has to deal with the fame and also the responsibility that comes with it. He might use his new - found popularity to spread the message of friendship and hard work, just like he did in his own world.
There are fanfictions where Naruto teams up with Earth's superheroes in the 'Naruto Earth Fanfiction' genre. Imagine Naruto joining forces with Iron Man. Naruto's chakra - based attacks combined with Iron Man's high - tech suits would make for some really cool battle scenes. They could fight against a common enemy like an alien invasion or a powerful villain who has both technological and mystical powers.
Obviously Naruto himself is the main character. But often, he'll interact with local Earth characters. Sometimes it could be a group of teenagers who befriend him and help him navigate the strange new world. They might learn from Naruto and Naruto will learn from them too.
One possible plot could be Naruto exploring the modern technology on Earth. He'd be amazed by things like cars and phones which are completely different from what he has in his own world. He might use his ninja skills in unexpected ways, like using his speed to compete in track races and becoming a local celebrity.
In some fanfictions, an Earth Dragon Slayer from another dimension enters the Naruto world. This character brings a whole new set of powers and a different perspective. They might teach the Naruto characters about the magic of dragon slaying, and together they face threats that neither could have faced alone. The Earth Dragon Slayer's ability to manipulate earth on a large scale could be a game - changer in battles against powerful ninja or new threats emerging in the Naruto world.
One interesting Naruto grown up fanfiction could be about Naruto becoming a great Hokage and how he manages international relations. Another might focus on his family life with Hinata and how they raise their children in a post - war Konoha.
One interesting plotline could be Ash having to adapt to the unique political system in Westeros. Maybe Ash gets involved in the power struggles between the great houses. Another could be Ash forming unexpected alliances, like with the wildlings. And Ash might also bring some new skills or knowledge from their original world that gives them an edge in Westeros.
One interesting Middle Earth fanfiction could be about a new adventure of Legolas outside of the main events of the original books. He might encounter a lost tribe of elves and have to help them solve a mystery related to an ancient magic that's starting to go awry.
One possible scenario could be that all of Naruto's friends are killed in a great battle. He survives but is left alone, haunted by the memories of his lost comrades. He might then wander the world, a solitary figure, with his only company being the memories of the past.
Well, he might join a magic guild. Since Naruto is strong and has his own set of skills like ninjutsu, he could easily adapt to the magic battles in Fiore. Maybe he'd learn some magic too, combining it with his ninja abilities to become an even more formidable fighter.
He might use his ninja skills to survive in Westeros. His ability to move stealthily and his combat skills could make him a formidable figure. He could also form alliances with some of the characters in Westeros, perhaps teaching them some of his ninja techniques in return for knowledge about the land.
