White: Assimilation: Poison Mist

After taking on the properties of the unique, red soil situated at the Seventh Front, the White Zetsu Army gains poisonous properties. Whenever they exhale or are cut apart and killed, they expel a red poisonous gas capable of leaving their opponents unconscious.

Additionally, the smog seems to share the red soil's high conductivity to electricity and was easily dispelled by a combination Lightning Release technique from Omoi and the Thundercloud Unit.

Trivia
