Jugo is a mentally unstable, sporadically fluctuating individual who seeks confinement and solitude from others. He is also the final member to be recruited into Hawk. Jugo first sought out Orochimaru in hope that he could find a cure for his impulses. Orochimaru had found and extracted certain enzymes in Jugo's blood and refined them into a more controllable form. With this, Jugo is able to change his form in order to compliment certain situations, and can even isolate the transformation to a single body part.
