This right hereKakuzu no contest. Hidan may have his curse, however Kakuzu doesnt even need to fight personally. He would simply let his mask/heart/things disassemble Hidan like a 3d jigsaw and be done with it.
Hidan isn'tWell hidan can't die kakuzu is a long range fighter.
This here makes sense.Kakuzu wont get cut because of his earth armour.... which is hard as diamond..... Kakuzu knows taking off hidans head is the way to beat him.. he can maybe pull something off with the tentacles hands of his, and a kunai
The post before yours was five years ago.Kakuzu will cut off his head and play soccer.
