If Hidan were to be captured and tortured, Kakuzu would be enraged. After rescuing Hidan, Kakuzu would stay by his side during his recovery. He'd be uncharacteristically gentle, making sure Hidan had food and water. Hidan would be touched by this side of Kakuzu that he rarely sees, and it would strengthen their relationship.
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 theme of forbidden love can also be present. Since they are both members of a somewhat sinister organization like the Akatsuki, their relationship might be seen as something that goes against the norms or rules of the group. This can add an element of drama and tension to the fanfictions, making them more engaging for the readers.
One possible angle in the 'Hidan and Kakuzu Hurt' fanfiction could be the consequences of their actions on themselves when they are in a vulnerable state. Hidan's immortality and Kakuzu's unique body structure could be explored in relation to how they experience and recover from harm. The fanfiction could also explore the reactions of other characters in the Naruto world to seeing these two usually tough characters in a hurt state, which could lead to some interesting character development for all involved.
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.
In a hurt/comfort fanfic, perhaps Kakuzu has some emotional turmoil. Hidan, despite his crazy nature, tries to comfort him. Hidan might sit down with Kakuzu and just listen to him talk about his past traumas. Hidan's presence, even without saying much of the 'right' things, could be a source of comfort for Kakuzu as he realizes he's not alone.

It also expands on their abilities. Maybe in fanfiction, Hidan discovers a new way to use his immortality in combat, or Kakuzu figures out a better way to manage his different hearts. This not only makes the characters more interesting but also adds new twists to the story.
Well, in fanfiction, one interesting aspect could be their unique relationship dynamic. Hidan's wild and impulsive nature contrasts with Kakuzu's more calculating and money - hungry side.
