Another common character might be Superman. If it's a crossover with the DC universe, Superman's sense of justice and his acceptance in his new world (Earth) could contrast with Naruto's banishment. Naruto could learn a lot from Superman about using his powers for good and also about being a symbol of hope, which could inspire him to find his own way to be a positive force even after being banished from his clan.
Often, in such fanfictions, Naruto's banishment from the clan forces him to re - evaluate his own values and goals. He might start to question the whole ninja way that he was taught in his original world. In a crossover with a post - apocalyptic world, for instance, he could learn that survival doesn't always depend on the traditional ninja skills but on things like cooperation, resourcefulness, and adaptability. This realization could then shape his character in a new and interesting way as he navigates through both the crossover world and his relationship with his former clan.
Naruto's character often becomes more jaded at first. Being banished makes him question his loyalty to Konoha. He starts to see the world in a different light and realizes that not everything is as it seems. He becomes more self - reliant as he has to fend for himself in unfamiliar places. In crossovers, he might learn new values from the other world he enters. For example, if it's a world where honor is highly prized, he might adapt and incorporate that into his own code.
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.
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.
One common plot twist is that Naruto discovers he has a hidden power that makes him a target in other villages. For example, he might find out he has a special bloodline that was kept secret. Another twist could be that the reason for his banishment was a false accusation set up by a hidden enemy within Konoha. This enemy might be working with an outside force to get rid of Naruto. Also, in a crossover aspect, he could end up in a different world or dimension where the rules are completely different, and he has to learn new skills to survive and potentially clear his name.
One popular 'Naruto banished crossover fanfiction' is 'Naruto in Another World'. In this fic, Naruto is banished from Konoha and ends up in a different universe where he has to adapt to new powers and challenges. It's a really exciting read.
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.
One common theme could be the clash of cultures. Naruto's ninja culture and the Pokemon trainer culture are very different. So exploring how characters adapt to this new culture they're exposed to is a theme.
One plot idea could be Naruto being banished to the world of One Piece. He could join the Straw Hat Pirates and use his ninja skills in new and exciting ways. For example, his shadow clone jutsu could be used for various tasks on the ship. Another idea is that he gets banished to the Bleach universe. He might learn about Soul Reapers and Hollows, and his chakra could be seen as a unique form of spiritual energy there. Maybe he could even train with the Soul Society to become stronger.
