White Zetsu Army

The White Zetsu Army consists of 100,000 copies of the white half of Zetsu, which is used as Akatsuki's main military strength during the Fourth Great Shinobi World War.

Creation
The Zetsu army was created using the chakra of the first seven tailed beasts. Madara Uchiha also used a clone of Hashirama Senju to connect the Demonic Statue of the Outer Path - which the tailed beasts were sealed within - to a cavern beneath Mountain's Grave where the army was made and stored. After Kabuto Yakushi captured Yamato, he used his studies of Hashirama's DNA and Yamato to improve the army's strength.

Appearance
Unlike the original, they have a complete face and a proper right arms and legs. They also seem to have small spikes protruding from their shoulders and on their back, but lack the venus flytrap-like extensions.

Confining the Jinchūriki Arc
Once Madara finished his preparations for the Fourth Shinobi World War, he had the Zetsu army mobilize to fight the Allied Shinobi Forces' 80,000-man strong army. Because of the size of their forces, Madara has the Zetsus travel below ground, to be led from above by himself to hide their numbers.
