Miasmo

Miasmo is the master of the Smoglings. He turned Captain Greenthumb into Sergeant Smogglor. He lives in a factory and is made out of gas. He commanded the Smoglings and Sgt. Smogglor to polute Parks and attack toys. Eventually, he gives permission to Sgt. Smogglor to use Smoglobs. When Smoglobs use gas on flowers, they become Miasmo Flowers, because they are named after him since he is gray like the flowers.
