Well, a Kakuzu and Hidan fanfic can be really interesting. Kakuzu is all about money and his unique abilities, while Hidan is this crazy religious fanatic. In a fanfic, they might be on a mission together. Maybe the author would explore their relationship in the Akatsuki more deeply, like how they tolerate each other's quirks. It could also show their growth as characters within the context of the story.
A good Kakuzu x Hidan fanfic has to capture their unique personalities. Kakuzu's greed for money and his calm, calculating nature, and Hidan's fanaticism and wild behavior. It should also have an engaging plot. Maybe a plot where they are forced to work together against a common enemy stronger than them. This would make them put aside their differences and show their loyalty to the Akatsuki.
The plot could involve Kakuzu being controlled by a more powerful and evil force. Naruto, after trying to reason with him and failing, has no choice but to kill him. This could also be a part of Naruto's growth, where he realizes that sometimes, in the face of extreme evil, killing is the only option to protect others.
In fanfiction, the emotional relationship between Kakuzu and Hidan can be complex. They are partners in the Akatsuki, and their bond might start from just being comrades in the organization. Hidan's wild and unpredictable nature could be both annoying and endearing to Kakuzu. Kakuzu, being more practical and money - loving, might initially tolerate Hidan but gradually develop a deeper connection as they face various missions together.
The emotional development between them is significant as it adds depth to their characters. It shows that even in a group like the Akatsuki, which is full of outcasts and killers, there can be relationships that are more than just alliances for power. Their evolving emotions can also be a way to explore different themes such as loyalty, friendship, and acceptance.
Kakashi could be a significant supporting character. He could provide Naruto with some advice or even join the battle alongside Naruto for a while. Another possible supporting character could be Hinata. Her gentle presence and belief in Naruto could give Naruto the extra motivation he needs during the fight.
In a Wattpad fanfiction where Naruto is trained by Kakuzu, Naruto might learn some unique and unorthodox ninja techniques. Kakuzu is known for his combat skills and his ability to use multiple elements. So Naruto could gain a more diverse combat style, perhaps incorporating some of Kakuzu's stealth and efficient killing moves. However, this would also be a very different kind of training from what he got in the original series, which might change his character development in unexpected ways.
Well, it could be about Kakuzu using his tendrils to capture Sakura for some unknown and perhaps dark purpose. Maybe he's under the control of an enemy who wants Sakura for her unique abilities. Or it could be a more complex story where the tendrils are not just for capturing but also for some sort of connection between Kakuzu and Sakura, like a strange form of communication.
Obviously, Kakuzu could be the main antagonist as he is the one using the tendrils to wrap around Sakura. His motives for doing so, whether it's for power, revenge or some other reason, would make him the force that Sakura has to oppose.
Often, Gai is paired with Kakashi in Hurt Kakashi fanfiction. Gai, with his unwavering belief in friendship and his eternal rivalry with Kakashi, can be a great character to interact with a hurt Kakashi. He might try to pull Kakashi out of his slump through their friendly competition. Also, Rin is sometimes included. Since she has a significant past with Kakashi, her presence in the fanfiction can either be a source of comfort or more pain, depending on how the story is written.
