Kandachi

is a missing-nin from Amegakure who was Hanzō's right hand man. Sometime after Pain killed Hanzō, Kandachi and a group of Ame ninja fled the country and went into hiding by taking over a village surrounded by a magnetic force that affects a person's chakra flow to the brain similar to genjutsu.

Abilities
Like his superior Hanzō, he fights mainly using the Summoning Technique. He can command the Conch King with hand seals. All of the hand seals performed also give the Conch King a signal to use a specified technique. One of the techniques are Ninja Art: Conch Whip, and another is Ninja Art: Conch Spear. Kandachi has shown a rare ability to cast a genjutsu on his opponent though the Conch King. The magnetic field caused by the tree strengthens this genjutsu, as the magnetism disrupts a person's chakra flow, similar to a genjutsu. Kandachi can also command the Conch King to propel above water using Wind Release.

Konoha History Arc
When Jiraiya brought Naruto Uzumaki to the forest for training, they encounter Tanishi who tells them of Kandachi's takeover. Naruto (disguised as Tanishi) and Jiraiya, pretending to be captured, meet with Kandachi, surprised to see Jiraiya again. Naruto's cover is blown when the real Tanishi arrives and Kandashi decides to feed the villagers to the Conch King. Naruto fights against Kandachi and the Conch King but their techniques knocks Naruto down every time. In the end, Naruto defeats them both with his first Great Ball Rasengan. It can be assumed that Pain eventually found and killed Kandachi and the other Ame ninja as Pain killed all friends, family and associates of Hanzō.
