His wife could be an original character created specifically for the fanfiction. She could be a strong - willed healer who helps Naruto when he first arrives in the new place. Their child could inherit Naruto's blond hair and blue eyes, and have a unique combination of Naruto's ninjutsu skills and the mother's healing abilities.
Maybe his family consists of a wife who was also banished from her own village for some reason. They bond over their shared experiences of being outcasts. Their family could also include an adopted child. This child could be from a war - torn area, and Naruto and his wife take the child in and raise it as their own, teaching the child about love and family in the process.
It's possible that Naruto's family includes his old friends who decide to leave Konoha with him when he is banished. For example, Shikamaru could be like an uncle figure to Naruto's children. And his wife could be a foreign ninja he meets during his travels. She has a different set of skills and a unique culture, which enriches their family life.
Perhaps his family consists of a group of fellow banished ninjas who become his surrogate family. There could be a strong - willed female ninja who becomes his partner, and together they have a child. And also an old sage - like figure who acts as the family's wise elder, guiding them through the difficulties of living in exile.
Perhaps a family of magical scholars. They would expose Harry to all kinds of ancient magic texts and theories. This would make Harry not only a better wizard in terms of practical magic but also in understanding the deeper roots of magic. They could be the ones to finally unlock the full potential of Harry's magic, which was stunted by his difficult upbringing at the Dursleys.
One possible plot could be that Naruto, after being banished, discovers a new place where he starts his own family. He might meet a kind-hearted woman who accepts him for who he is. They could have a child together, and Naruto would be determined to protect his new family from any threats, including those who might still hold a grudge against him from his past in Konoha.
In the 'banished naruto has a family fanfiction', Naruto might be banished and end up on an island. There he meets a group of outcasts like himself. Among them, he finds a partner and they start a family. Their family grows up learning Naruto's ninja ways and they all strive to create a better life on the island, away from the politics and judgment of the ninja world that banished Naruto.
One possible reason could be fear. The villagers have always feared the Nine - Tails within Naruto. His family might banish him out of this same fear, not wanting to be associated with the potential danger he represents. Maybe they think that by banishing him, they can keep the village safe from the Nine - Tails' power getting out of control.
Hinata could be a likely member. She has always had feelings for Naruto. Sakura might also be part of it, as she is an important female character in the Naruto series. And perhaps Tenten, who is strong and independent and could be attracted to Naruto's new winged form.
Well, it could be some of the younger generation characters who have shown great potential. For example, Boruto could be one of them, as he has his own unique set of skills and abilities. Another could be Sarada, with her Sharingan and growing ninja skills. And maybe Mitsuki, with his snake - like abilities.
It could be the Malfoy family. Imagine Hermione being switched with a Malfoy child. Draco would be in for a huge shock when he realizes that the sister or brother he thought he had is completely different. And Hermione would have to deal with Lucius and Narcissa's pure - blood mania.
Potential members could include Tenten from Naruto's world. She might be interested in Naruto's adventures in a different universe and become part of the harem. In Starfire's world, there could be a scientist - type character who is fascinated by Naruto's ninja abilities and the concept of chakra. This character could start to develop feelings for Naruto as she studies him more closely, thus joining the harem.
Sakura could be a potential member. She has a long - standing relationship with Naruto and her skills as a medical ninja could be an asset to the group. Ino might also be part of it. Her mind - control jutsu and her strong personality could add an interesting dynamic. Tenten could be there too, with her weapon expertise. These characters already have connections to Naruto in the original story, and in a harem fanfiction, they could form a unique relationship with both Naruto and Kurenai.
