Major Mucus

Major Mucus is the evil dictator of Planet Mucus, a planet completely made of slippery green slime. Any who oppose him are hung over his huge, slippery pits and devoured by the Mucus Phlegm Brain monster. When Major Mucus heard that Queen Slug-For-A-Butt was having a special weapon delivered to her by Psy-Crow, he decided to steal it.

The weapon in question was the super suit that ended up in the posession of Earthworm Jim. Mucus and Jim battled in one of the phlegm pits over the Mucus Phlegm Brain for posession of the suit. Jim emerged victorious, but Mucus later attacked Jim with sumo-launching trebuchets and slime UFOs. Jim blew up the platform Mucus was standing on, sending him back into the phlegm pit.
