Kakuzu is a member/Accountant of Akatsuki and partner of Hidan , Kakuzu is from Takigakure, the Village Hidden in a Waterfall. Kakuzu is a very powerful shinobi, he posses five hearts which allow him to posses five lives. Kakuzu is able to replace these hearts if they are destroyed by removing them from a defeated opponent. Kakuzu is also able to use his hearts as weapons, the heart can be released from his body and take control of the string and build a body to use to fight with.

Another technique is that he is able to shield his body from any attack if he is able too.

Fire

Using a bull like mask this monster is the same as the rest using Kakuzu's string to form a body to use. It can release lighting bolt's at an unlimited pace.

Wind

An eagle styled mask that has a four legged body with wings, it releases huge tornado style attacks at an unlimited pace. Fusing its technique with the fire makes it almost unstoppable.

Water
