Naruto 665 Trivia and Technique Highlight

Black Zetsu When Madara was on the verge of death, he manifested his will and covered one half of White Zetsu with it, creating Black Zetsu. This in turn made the complete Zetsu partially a clone of Madara, albeit weaker. Both halves later accompanied Obito to Amegakure to locate Nagato, who had unknowingly been given Madara's Rinnegan as a child. Zetsu then accompanied Obito as he approached the orphans, introducing himself as Madara Uchiha. Black Zetsu has demonstrated the ability to "record" the things he sees, as he has stated that he recorded the battles between Sasuke and Itachi, and between Kisame and Killer B. He is also capable of showing these "recordings" through unknown means. Black Zetsu is also a very powerful sensor, as he was able to sense Naruto Uzumaki and Killer B as soon as they touched the ground upon leaving the Island Turtle, which was some distance away. As a manifestation of Madara's will, Black Zetsu is able to telepathically communicate with Madara. Upon being bisected and immobilised, Black Zetsu separated from the white portion of his body by seeping the black matter in his lower half into the ground and subsequently forming it into a new upper body. This new body was then able to meld with and control a weakened Obito's body, forcing him to perform the Outer Path: Samsara of Heavenly Life Technique, as well as keeping him alive while melded, as otherwise Obito would have died as a result of using the technique.

With Obito weakened after the tailed beasts were extracted from him, Madara enacted his trump card. With this, Black Zetsu suddenly emerged from underground and restrained him. As he began to meld with half of Obito's body, Madara was able to force Obito into using the Outer Path: Samsara of Heavenly Life Technique. Apologising as this all unfolded, Black Zetsu noted that from the start, this was his sole purpose for existing. With Madara's revival a success, Black Zetsu attempts to retrieve Madara's Rinnegan eye from Obito until Minato and Kakashi intervene. Black Zetsu once more melds with Obito's body, using the Uchiha's body to battle his former team and noting that his merger was the only thing keeping Obito alive. While both sides were at a stalemate, the Demonic Statue of the Outer Path emerged from Obito's artificial body, quickly being teleported. Afterwards, Black Zetsu again attempted to take the left Rinnegan. Obito, managing to resist Black Zetsu's control of his hand, told Kakashi to destroy the Rinnegan. Black Zetsu, realising what the summoning of the Demonic Statue meant, informed his enemies that Madara has regained his right Rinnegan. Standing to face Minato and Kakashi in battle, Zetsu complained about the duo's stubbornness before Gaara arrived along with Sakura and a dying Naruto to Minato and Kakashi's location, Black Zetsu managed to steal Kurama's Yin half when Minato tried to transfer it into his son, thus becoming its jinchūriki. Soon afterwards Zetsu was joined by Madara who complained about having to come all the way there.
