Miasmo
Miasmo is the master of the Smoglings. He made the Smoglings send Captain Greenthumb to Exhaustia. He then changed him into Sergeant Smogglor. He lives in a factory in Exhaustia and is made out of smog. He commanded the Smoglings and Sgt. Smogglor to polute Parks and attack toys. Eventually, he gives permission to Sgt. Smogglor to use Smoglobs when it turns out his Zapow doesn't affect Chibi-Robo. When Smoglobs use gas on flowers, they become Miasmo Flowers, because they are named after him since he is gray like the flowers and is made of gas. When Sergeant Smogglor starts to turn back into Captain Greenthumb, Miasmo comes and changes him back into Sergeant Smogglor and allows him to use a Super Zapow. Later when he changes back again, Miasmo does the same thing except he allows him to use a Extreme Zapow.
