Kakuzu



Kakuzu (角都) was a member of Akatsuki and the partner of Hidan. Despite their mutual dislike of each other, their teamwork was almost flawless, because they complemented each other's abilities extremely well. Kisame laughingly referred to Hidan and Kakuzu as the "Zombie Brothers" due to the fact that they could not die in a sense.

Background
When he was still a loyal elite ninja to Takigakure, Kakuzu took on a mission to assassinate Hashirama Senju, the First Hokage. This mission, however, ended in failure due to the might of Hashirama's Mokuton jutsu. Despite the insurmountable danger faced in the mission, what awaited his return to his village was the stigma and harsh punishment associated with the failure of his objective. In response to this treatment, a wrong levied against a shinobi who had put life and limb on the line for his village, Kakuzu came to hold a violent hatred to his village as he escaped from imprisonment. In his flight from the village, Kakuzu killed the village elders, took their hearts, and fled with knowledge of the village's most prized forbidden techniques. He eventually joined Akatsuki, and was given a number of partners, most of whom he killed, due to his short temper. This is why he has eventually partnered with Hidan, whom he could not kill. Pain stated that his reason for joining Akatsuki was "resources".

Appearance
Kakuzu was a tall, muscular man, second in height in Akatsuki (after Kisame Hoshigaki). He wore a white hood and a black mask on his face with his eyes being the only visible part. Underneath, his mouth was stitched together at the edges, and his hair was long and untidy. His eyes have an unusual coloring: green pupils and red scleras. His clothing included the traditional Akatsuki cloak and the forehead protector of his home village with a scratch in the middle which symbolized that he was no longer loyal to it. He also had dark green nail polish and his Akatsuki ring with the kanji for North (北, hoku) was placed on his left middle finger. His entire body was covered with stitches and appeared to be sewed together. This was a result of the unique jutsu that he possessed - Earth Grudge Fear. On his back were four masks each resembling those of ANBU where he stored his additional hearts.
