Naruto battle: Kakuzu vs Hidan x2

Still Kakuzu. Far more versatile, has the experience and already knows how Hidan's main technique/techniques work and his fighting style.

Kakuzu

Kakuzu low-mid difficulty.

Kakuzu.

Kakuzu

Kakuzu.

Pretty much what SAR said and because Hidan doesnt have a good enough AoE attack (He doesnt even have 1) to even make a dent in Kakuzu

.

Without knowledge it's a 50/50 match-up.

But with it there isn't really anything Hidan could do that Kakuzu hasn't already planned for. Although I don't think it would be an easy fight either way. We did see Hidan tank one of Kakuzu's strongest attacks while not transformed with no injuries. Also Kakuzu was confident that Hidan was actually going to kill Shikamaru despite seeing what he was capable of beforehand while backing Asuma up. So even Kakuzu doesn't think Hidan is weak enough to low or mid dif if he could beat him.

Kakuzu still wins

No, it isn't.

Kakuzu for a healthy majority.

Superior versatility & ranged attacks to counter Hidan who needs to get close to get any work done. And is already more than familiar with his partner(s) whole shtick. So good luck getting any blood.

And while he can't put them down, he can win by destroying the body of the Hidans and calling it a day.

Hidans win. Kakazu was getting cornered by him when puppeted.

Kakuzo wins with some difficulty
