Black Salamander

The was a creature native to Amegakure that was famous for the deadly poison its body produced. After its death, Hanzō during his childhood, had its venom sac implanted into his own body, thus granting him the ability to create the same poison, as well as allowing him to develop a resistance to this particular poison. Due to the consequence that even his own breathing would release the toxin, Hanzō quickly became feared as "Hanzō of the Salamander".
