It could be Sasuke's sister, if there was one in the fanfiction world. She might share some of Sasuke's traits but also have her own unique personality that attracts Naruto.
Another possibility is Sakura. Although she has feelings for Sasuke in the original, in this fanfiction, the story could be rewritten so that she realizes her true connection with Naruto and they end up getting married at 12. Their dynamic would be quite different from the original, with Naruto having to prove himself in a new way to Sakura.
It could be a self - made queen from a far - off land. Maybe she is a powerful magic user who has united her land through her own strength and wisdom. When she meets Naruto, she is intrigued by his unique ninja abilities and they fall in love.
It could be an original character created specifically for the fanfiction. Maybe an empress from a far - off land that Naruto discovers during one of his adventures.
Maybe Tsukuyomi could be the goddess Naruto marries in fanfiction. Tsukuyomi is associated with the moon. Naruto, with his connection to the Nine - Tails, could have an interesting dynamic with a moon - related goddess. Her powers could help Naruto in controlling the Nine - Tails better or even give him new abilities related to the moon, like enhanced night - time combat skills.
Gaara, Temari's brother, would surely be a significant supporting character. He would be involved in the decision - making regarding Temari's marriage. Hinata could also be a part of it, maybe as a friend to Naruto, offering her gentle support and understanding throughout Naruto's relationship journey with Temari.
The princess might be from a land that was once at war with the Hidden Leaf. Her marriage to Naruto could be a symbol of peace and unity. She could be a strong ninja in her own right, with skills in stealth and combat, and her personality could be a mix of grace and fierceness.
Obviously, Naruto and Sakura are the main characters. Naruto, the energetic and determined ninja, and Sakura, the strong - willed and intelligent medic - ninja. Their relationship is the central focus of this type of fanfiction.
It could be a long - lost heir to a powerful, almost forgotten dynasty who resurfaces. This heir, being royalty, might have some special powers or knowledge. And Naruto, being the hero he is, could be drawn to her because of her unique qualities and the potential she holds for bringing about positive change in the world.
Any fanfic writer who enjoys exploring unique pairings could write a 'naruto marries artemis fanfiction'. It might be an experienced writer who has written many crossovers before and sees the potential in bringing Naruto and Artemis together. They would be able to play with the different character traits and create a whole new story.
