Weezing

Weezing is another gas emitting Pokemon from the Kanto region. It is the evolved form of Koffing. Weezing takes of a grotesque appearance of having 2 heads attached to each other with a third on supposedly growing below it.

Weezing made its first appearance after James' Koffing evolved, something that he was very happy to have happen. Weezing played a vital role in the villainous team's many thefts and getaways by emitting a massive amount of smoke and gas as a way of reducing other's eyesight and breathing, preventing them from doing anything to stop the villains' crimes. The gas is very often blown away by a Pokemon with Gust, such as Ash's Pidgeotto.
