Tobi (Zetsu)

This Zetsu is an unnamed clone and subordinate of Madara Uchiha and was one of Obito's bodyguards alongside White Zetsu.

Background
He was one of many Zetsu clones created using the Demonic Statue of the Outer Path. It was created from the Demonic Statue of the Outer Path and Hashirama's living clone where it served as one of Madara Uchiha's loyal minions and spies. He met and befriended Obito shortly after the latter was saved by Madara. He along with White Zetsu enjoyed annoying and teasing Obito about things such as what he murmured in his sleep. Over time, the duo became friends with the young Uchiha.

Months into Obito's rehabilitation, White Zetsu urgently alerted Obito that Kakashi and Rin, whose names Obito would constantly murmur while asleep, were outside and were being attacked by Kirigakure shinobi. Resolved to save his friends, Obito tried to break a wall to get outside, but destroyed his artificial arm. Seeing how desperate Obito was, the Zetsu attached himself to the former to replace his limb. Although Obito was sceptical about whether they had permission to help, White Zetsu said that Madara would allow them to do this.

Personality
When first meeting Obito, "Swirl" Zetsu was playful and enjoyed teasing him about things. Although Obito was initially hostile, the two befriended each other during the formers rehabilitation. He believes that the Eye of the Moon Plan is good for mankind. He also believes that Madara is a good guy at heart, as shown when he and White Zetsu decide to help Obito without Madara's permission.

Appearance
"Swirl" Zetsu is easily distinguished by the swirl-pattern of his face that only shows the hole in the place of his right eye. Though it has a swirl pattern running from his head down to his waist. These swirls are shown to be able to open in a similar manner to the fly-trap extensions. It's body overall is the most unique body produced out of any other Zetsu Clone. The Zetsu shows no visible orifices at all and lacks the venus flytrap-like extensions.
