Poison Mist

Chakra is kneaded within the body and then changed into special chemical substances. It is then ejected through the mouth. When this substance comes in contact with the air outside the body, it instantly changes and is transformed into a mist of deadly poison. The poison's ability to kill is tremendous, as even just breathing in a small amount will mean the end of the target's life. As this technique combines ninjutsu, chemistry, and medical knowledge, using it requires fine chakra control and advanced ability in medical ninjutsu.

When used by Hanzō's Salamander, the effects of the gas are almost instant, making the targets' bodies feel numb after just a few seconds. With the targets paralysed, Hanzō can attack at his leisure with his kusarigama.

Trivia

 * In Naruto: Ultimate Ninja 3, almost every character can use this technique by finding a Poisons Book for Shizune.
