Doku (毒 - Litterally meaning "Venom")
Doku is an Orginization started by Kabuto Yakushi, in order to assure the downfall of Madara's Imposter. Kabuto originally used Edo Tensei to revive the Shinobi involved, however he enhanced the jutsu by taking more dead bodies and merging them with the Edo-Tensei awakened shinobi, making them fully living once again. He called this technique Fujun'na, Shinsei, meaning 'Impure Rebirth'.
