Weezing is the Poison Gas Pokemon. It is the evolved form of Koffing. In Ben10fan3's rebooted Pokemon timeline, it evolves into Chokking.
Weezing mostly resembles two Koffing stuck together, except the face on the right is much smaller, and the smaller face has a circle under its mouth instead of a skull and crossbones. Weezing has much bigger teeth then it had as a Koffing, and it's eyes are much bigger.
