Another pair Naruto could focus on is Kiba and Hinata's sister, Hanabi. Kiba has a bold and straightforward personality, while Hanabi is strong - willed. Naruto might think they would make an interesting couple and start by getting them to work together on a small mission for the village.
He could pair up Shikamaru and Temari. They already have a bit of a connection and Naruto, seeing their potential, could nudge them further into a relationship. He might arrange for them to have more diplomatic meetings that turn into personal get - togethers.
One possible plot could be that Naruto, with his energetic and determined nature, decides to play Cupid in the Hidden Leaf Village. He might start by trying to set up his friends like Sakura and Sasuke. He could use his ninja skills to create 'coincidental' meetings between them. For example, he arranges for them to be in the same training area at the same time. Naruto, believing in true love, thinks he can make their relationship work.
A great pairing could be Naruto and Samus. Naruto's energetic and determined nature combined with Samus's cool and calculated approach would create an interesting dynamic. Another good pair could be Sasuke and Samus. Sasuke's brooding and powerful ninja skills could contrast well with Samus's high - tech combat abilities. Also, Kakashi and Samus could be an interesting pair as Kakashi's wisdom and experience as a ninja could complement Samus's combat knowledge.
Another character could be Kakashi. Kakashi's wisdom combined with Byakuya's combat skills and Naruto's determination would make for a really engaging story. Kakashi could study Byakuya's techniques and try to incorporate some of that into Naruto's training, while also trying to understand Byakuya's motives in the Naruto world.
Naruto and Hermione would be an interesting pair. Hermione's intelligence combined with Naruto's determination could lead to some great adventures. They could study magic and ninjutsu together, with Hermione helping Naruto understand the more complex magical theories, and Naruto showing Hermione how to be more physically tough.
Sasuke could be one. Given their complex relationship, there could be a situation where Sasuke's newfound power or different ideology leads him to fight and beat Naruto in a fan - made story.
Naruto might end up teaming with some of the more sane inmates who have a sense of right and wrong. For example, he could form an alliance with a reformed criminal who wants to help Naruto navigate the complex and dangerous world of Arkham. Together, they could try to expose the corrupt elements within the asylum.
Shikamaru would also be an interesting choice. He's very intelligent, and a female Naruto could learn a lot from him in terms of strategy. Their friendship could develop into something more as they spend time together planning how to deal with threats to the village. Shikamaru's laid - back attitude could also balance out a female Naruto's more energetic and impulsive nature.
A former friend or teammate who has turned to the dark side could be an antagonist. For example, if someone like Sasuke had completely given in to the dark side and decided to attack Naruto for some reason. Or it could be a new and mysterious character who has a vendetta against the Uzumaki clan and sees Naruto as the prime target to take revenge on the clan. This character could be very powerful and use their abilities to beat Naruto up.
Sasuke would be a great character to pair with Naruto in this type of fanfiction. Their rivalry could be enhanced with the addition of the Boosted Gear. Sasuke might be initially jealous of Naruto's new power but then see the potential of working together to defeat a common enemy.
Naruto and Tsukune would be an interesting pair. Naruto's energetic and determined nature combined with Tsukune's kind heart and his own growth as a character in the Rosario world could lead to some great interactions. They could learn from each other's ways of dealing with challenges and protecting their friends.
