Jūgo

Jūgo (重吾, Jūgo) is a shinobi from an unknown clan, who was being held at Orochimaru's Northern Hideout which was also where most of Orochimaru's secret human research was conducted. Jūgo was said to have gone to Orochimaru of his own free will, hoping that Orochimaru would cure him from his rages. He was later recruited as a member of Sasuke Uchiha's group Taka, which was initially called "Hebi" at the time of its creation.
