They could also develop together in terms of their worldviews. Naruto's belief in never giving up and protecting his friends could inspire Tigress to be more involved in the affairs of her own world. Meanwhile, Tigress's respect for authority and tradition could teach Naruto the importance of structure and hierarchy in the ninja world. This mutual development would make their relationship more interesting and dynamic in the fanfiction.
Tigress, on the other hand, could develop a softer side. Being around Naruto's positive and energetic personality might make her more open and expressive. She could start to show more emotions and learn to trust others more easily. In a fight, she could incorporate some of Naruto's quick - thinking and adaptability into her own combat style, making her an even more formidable fighter.
For Naruto, his growth could be shown in relation to Tigress's no - nonsense attitude. He might become more disciplined in his training. For example, he could learn to control his rasengan better by observing Tigress's precision in her attacks. His character could also become more introspective as he tries to understand Tigress's more reserved personality.
The tigress can be developed by showing her softer side through her love for lemons. For example, she might be fierce in the wild but when she comes across a lemon grove, she becomes gentle and almost child - like in her excitement. The viper could be developed as a misunderstood character. Maybe he uses his venom not for harm but to protect the lemon trees from those who would destroy them. His slithering and stealthy nature can be used to show how he carefully guards the lemons.
For Tai Lung, in fanfictions, his character could be developed by exploring his backstory more deeply. Maybe there were events in his childhood that made him so desperate for the Dragon Scroll. This could make readers sympathize with him more. Tigress could be developed in terms of her relationships with other characters. For example, how her relationship with Tai Lung affects her relationship with the Furious Five. She might become more independent from the group as she spends more time with Tai Lung. And Tai Lung could be developed to be more adaptable. He could learn new ways of thinking and being from Tigress, and Tigress could learn to be more assertive from Tai Lung's boldness.
They could also develop their relationship through training. Instead of just training separately, they start training together as a couple. This would involve creating new combat techniques that combine their different fighting styles. It would not only strengthen their bond but also make them a more formidable team in case of any threats to the Valley of Peace.
For Naruto, you can focus on his growth in a different aspect. Since he already has his ninja skills, in a story with Aplessia, he could develop his emotional intelligence further. For example, learning how to better understand Aplessia's more complex and perhaps different emotional range compared to his friends in Konoha. For Aplessia, you can start by giving her a backstory. Maybe she has a troubled past that made her the way she is, and as she interacts with Naruto, she starts to open up and become more confident.
For Naruto, you could focus on his growth in a new environment. Since he's in a different world with Natsuhi, he might have to adapt his ninja skills. Maybe he starts to learn some new techniques from Natsuhi's world. For Natsuhi, you could show her becoming more confident. Naruto's presence and his can - do attitude might inspire her to be bolder. For example, if she was shy about using her powers before, she could start to use them more freely.
In fanfiction, Naruto could be developed by having him face new moral dilemmas when interacting with Yubel. His character could grow by learning about different forms of power that Yubel represents.
Towa could be developed by exploring her past. Maybe she has some traumas from her own world. Meeting Naruto and seeing his determination could inspire her to face her past. Also, her relationship with Naruto could soften her hard - edged personality as she becomes more involved with the kind - hearted people in the Naruto universe.
To develop Naruto's character in relation to Anko, he could be put in situations where he has to rely on her. This would make him realize that he doesn't always have to be the one in the lead. Anko could also introduce him to different parts of the ninja world that he hasn't explored yet. For Anko, Naruto could be the catalyst for her to change her somewhat aloof and solitary nature. His friendship could make her more sociable and collaborative, and she could start to see the value in teamwork, which is something Naruto highly values.
Naruto's character in Anbu could be developed by exploring his relationships with his Anbu teammates. He might learn new ways of thinking and fighting from them, and this could affect how he interacts with Ayame. Ayame, on the other hand, could be developed by having her face some sort of danger that forces her to become stronger. Naruto could then be the one to help her train and gain confidence. This would not only strengthen their relationship but also develop her character into a more independent and capable person.
For Naruto, he could develop by learning more about leadership from Tsunade. He already has his own unique style, but Tsunade's wisdom in leading the village could give him new insights. Sakura could develop her medical ninjutsu further under Tsunade's guidance and also become more confident in her combat abilities. Tsunade herself could develop by seeing the new generation, Naruto and Sakura, grow and be inspired to take on new challenges for the village.
