Black Zetsu (GD)

, was created from the will of Kaguya Ōtsutsuki to secure her revival. In addition to that, it was also the mastermind that instigated many of the events that shaped shinobi history.

Most recently in the past, he was responsible for manipulating Madara Uchiha, and through him, Obito and Nagato to bring back Kaguya his mistress, to reestablish Ōtsutsuki rule. These plans however, were cut short by Naruto and Sasuke, with the help of their friends, past Kage and Hagoromo Ōtsutsuki himself. Also, he was responsible for corrupting Toneri on the moon, through a "doppelganger" to cause him to drop the moon down on the world, eradicating it and avenging his master. This too, was thwarted by Naruto and friends, leaving Wicked Tongue with little options left.

This forced Black Zetsu's countless doppelgangers into hiding far from Naruto or Sasuke, amassing an army in secret. Even though his main body was sealed within Kaguya, Kaguya's will was able to use his doppelgangers to complete his plan and wait out the two legends until they died, along with a few other powerful shinobi. With his chance at hand, he seized control of the world with his underground army. Few nations have survived his initial conquest to unify the world under a single regime.

Taking a human host, Black Zetsu's wicked and negative emotions, amplified by his whole army, led to the creation of another Zero Tails, one that he has become the embodiment of, and by extension, its jinchūriki. With his large army and newfound Dark power, only a few strongholds stand in his way before his revolution is complete and Kaguya can come back to a quelled world. This makes him a main antagonist in Naruto: The Golden Darkness.
