White Zetsu (Biological Weapon)

was a living weapon that resided in the Mountains' Graveyard ruins.

Appearance
While the nature of its form is essentially the same as the other White Zetsu, this version is massive, appearing as a random amalgamation. It has two extra arms that have scythes for hands and three Zetsu heads, two of which are located on the chest.

Abilities
Its physical strength was regarded as being off the charts, being capable of overpowering shinobi. Despite its intellect being seeming low, it could regenerate itself, and simultaneously utilise lightning, fire and wind nature transformations.

Versus Momoshiki Arc
After four robbers entered the abandoned mine it was residing in, it killed three of them, leading to the fourth criminal fleeing and the village informing the Konohagakure shinobi.
