To write a great Naruto banished married crossover fanfiction, start with a strong premise. Decide early on why Naruto is banished and who he is married to. Let's say he's married to Temari. The banishment could be because of a prophecy that some in Konoha misinterpret. For the crossover, if it's with a world of mythical creatures, research those creatures. Develop the relationship between Naruto and Temari. Maybe they have different views on how to deal with the new world they are in. Write engaging dialogue that shows their personalities and how they grow as a couple in this new and difficult situation.
A really interesting plot could be that Naruto is banished due to political reasons in Konoha. He's married to Ino (just as an example). Then, through some sort of magic or strange occurrence related to the crossover element, they are transported to a world full of magic users. Naruto has to learn how to use magic while still holding on to his ninja skills. His marriage to Ino is both a source of strength and a challenge as they face the new and often dangerous situations in this foreign land.
One common theme could be redemption. Maybe the banished character has to go through a journey to prove themselves worthy again, especially in the context of their marriage. Another theme might be the struggle against the stigma of being banished while trying to maintain a relationship.
One common theme is redemption. Naruto, being banished, often has to prove himself all over again in the new crossovers, seeking redemption for whatever led to his banishment in the first place.
He could marry Hinata. Even though he's banished, Hinata might follow him because of her deep love for him. Their relationship could develop further outside the village, and they could get married and start a family.
If Naruto is banished to the My Hero Academia universe, Deku could be his ally. Deku, with his determination to be a hero, would understand Naruto's drive to be recognized. They could share their experiences of being underestimated at first. Also, in a crossover with the Inuyasha world, Kagome could be an ally. She has a kind heart and could help Naruto understand the new world he's in. Her spiritual powers might also interact in an interesting way with Naruto's chakra.
