Kakuzu was the other half of the "Zombie Combo" and another immortal member of Akatsuki. Kakuzu was expelled from Takigakure village for failing in the assassination of Hashirama Senju. A lifetime of bounty hunting and clashes with various ninja villages granted Kakuzu access to a wealth of forbidden techniques, adding more to his intimidating aura. Motivated by money rather than ethics, Kakuzu used his skills to become a bounty hunter before working with Hidan. Though the two were often at odds, they did make a great team when it came to death and destruction. Kakazu developed his unique ability to steal other hearts and use them for his own use and is one of the oldest characters in the series, dwelling from the First Great Ninja War. Almost immortal, he can only be annihilated if he is slain for the fourth time, but with the combined efforts of Team Asuma, Kakashi Hatake, and Naruto's Rasenshuriken, Kakuzu was conquered.
