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 Mountains' Graveyard 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 white side, which is only half of a the Zetsu, they have a complete face, with properly defined right arms and legs. They also have a different body texture a more rough, hard like appearance as opposed to the original's smooth texture body. After Kabuto uses Yamato to further enhance their abilities, the Zetsu gain small spikes that protrude from their shoulders and back. These Zetsu however, lack the Venus flytrap-like extensions, that the original had, and have what seems to be cracks or all over their bodies. They also have a zig-zag pattern from the the diaphragm down to the groin, and then down each leg reminiscent of the originals fly trap-like extensions.

Abilities
As the main force of Madara's army, the White Zetsu are presumably adept for combat. With Kabuto's offer of increasing their strength, they might be even stronger than before. Like the original Zetsu, they are at least able to use the Mayfly to travel underground.

Shinobi World War 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-person 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. This was discovered by Muta Aburame and is reported to the various commanders. The Second Division, led by Kitsuchi, as well as elements from the Fifth Division, unearth and attack a detachment of 20,000 White Zetsus traveling directly underneath them.
