Jugo

Jugo (重吾, Jūgo?) is the final character to be recruited for Taka. He is mentally unstable, sporadically fluctuating between a bloodthirsty and a docile personality. While in the former mindset, Jugo kills anyone around him without remorse until he somehow returns to his senses, at which point he seeks confinement or solitude to protect others from himself.[112] It is only through Sasuke Uchiha's promise to keep him in check and the fact that Sasuke reminds him of Kimimaro that Jugo agrees to join Taka.[101] Sometime in the past, Jugo sought out Orochimaru in the hopes that he could find a cure for his impulses. While examining him, Orochimaru isolated enzymes in Jugo's blood that caused him to radically transform the appearance and capabilities of his body. By extracting these enzymes, Orochimaru was able to reproduce the transformation in his own subordinates, making the cursed seal.[113] Though Orochimaru's refined transformations are more controllable, his subordinates are limited to using only one form. Jugo is able to alter his transformed state to suit the situation, and can even isolate the transformation to a single part of his body.[112] He can also fuse some of his own flesh to someone who has, or has had, the cursed seal in order to heal their injuries, but he regresses to a younger age as a side-effect. He and Suigetsu are captured by samurai of the Land of Iron after a botched attempt to assassinate Danzo during the Kage summit. He is voiced by Shūhei Sakaguchi in the Japanese version.
