One interesting aspect could be the character development of Sakura. In the original series, she might not have had as much interaction with Haku and Zabuza. In the fanfiction, she could show new skills and a more assertive personality while saving them. For example, she might use her medical ninjutsu in creative ways to heal their wounds.
The plot twists are often a highlight. In the fanfiction, the situations that lead to Sakura having to save them could be very different from the main storyline. It could involve new villains or challenges that weren't present in the original anime, making for a fresh and exciting read.
One possible plot could be that Sakura, being a skilled medic in the Naruto universe, comes across Zabuza and Haku who are severely injured. She decides to use her medical jutsu to save them. Maybe she's on a solo mission and her sense of morality makes her help them, despite them being former enemies. This could then lead to an interesting alliance or at least a mutual respect between them.
One interesting aspect could be the exploration of their relationship in different scenarios. For example, how they might interact in a modern - day AU (alternate universe). Another aspect could be delving deeper into their backstories and how it shapes their bond. It could also be fascinating to see how fanfiction writers develop their characters further, perhaps giving Haku more agency or exploring Zabuza's softer side.
Sakura's character could develop in terms of her understanding of the grey areas in the ninja world. Saving Zabuza and Haku, who were once considered villains, might make her realize that not everything is black and white. She may become more open - minded and less judgmental.
Well, in the original, Haku and Zabuza die. But in this fanfiction, Sakura's actions change that fate. This is a huge deviation as it completely alters the expected outcomes for those characters.
The relationship between Zabuza and Haku as mentor and student is also a great area to explore. How Zabuza taught Haku his skills, and how Haku learned not only the physical skills but also the mental and emotional aspects of being an assassin can be the focus of a fanfiction. It could also show how their relationship evolved from a strict teacher - student one to a more equal and deep - rooted bond.
His confidence could grow significantly. By being able to save two powerful ninjas, Naruto would prove to himself that he is capable of great things. He may start to believe more in his own abilities and take on more challenging tasks without hesitation. For example, he might be more willing to take on stronger opponents in future battles.
The relationship between Zabuza and Haku is complex and full of depth. In fanfics, it can be explored further. Zabuza is a tough and feared ninja, while Haku is gentle yet deadly. Their contrast makes for an interesting dynamic, and fanfics can play around with how they interact and support each other.
I'm sorry, but I can't recommend lemon (adult - themed) fanfiction as it goes against ethical and appropriate content guidelines.
Naruto might develop a deeper understanding of the power of friendship and how it can cross enemy lines. His act of saving Haku could make him more determined to see the good in everyone. For Haku, he could start to question his loyalty to Zabuza and consider a different way of life, which is a significant character development.
One interesting aspect is the different relationships she can have. For example, she could have a unique friendship with Naruto or other characters. Her character can be developed in ways that explore her femininity in the context of the Naruto world, which might include different clothing styles or social interactions compared to the male Haku in the original story.
