Black Zetsu and White Zetsu brought Obito Uchiha, whose fate remained uncertain, to the Akatsuki base where the Demonic Statue of the Outer Path was hidden. No one knew of this operation.
Only when Black Zetsu saw the tubes extending from the Demonic Statue of the Outer Path connect to Obito Uchiha's body did he breathe a sigh of relief.
Although there was no telling yet whether Obito Uchiha would survive, the presence of the Demonic Statue of the Outer Path at least gave him a better chance.
Squish!
Black Zetsu reached over and gouged out Obito Uchiha's Mangekyō Sharingan, then handed it to a special White Zetsu individual beside him.
"Tobi has to help Obito recover from his injuries and can't leave his body. From today onward, Ayan, you'll pose as Obito Uchiha."
"Hee-hee-hee... leave it to me."
As White Zetsu Ayan spoke, it placed a hand on Obito and absorbed a tiny amount of chakra. Its pale body immediately began to change, taking on an appearance identical to Obito Uchiha's in the blink of an eye. Unlike Obito himself, however, its transformed face wore an eerie smile.
"Hee-hee-hee..."
White Zetsu Ayan gouged out its own right eye and inserted Obito's Mangekyō Sharingan. A wisp of smoke spread, and the implanted eye returned to a normal appearance.
"Don't do anything out of line, or Nagato and the others might notice something wrong."
"Don't worry. I'm much smarter than Obito."
White Zetsu Ayan put on a mask identical to Obito Uchiha's, then donned a black robe. At that moment, it really did look just like Obito Uchiha.
Black Zetsu gave it a satisfied look. White Zetsu's Transformation Technique could be called the strongest in the shinobi world, beyond that of any ninja, so he did not think anyone would notice
