Vice President Greg appeared in the Season Eleven episode, 「Lice Capades」, as a louse that lives in Clyde's hair. He serves as the main antagonist in the episode.
Background
The Vice President doesn't believe Travis Mayfield, the lice protagonist, that the world (Clyde's body) is conscious. After Clyde washes his hair with the special shampoo given by the doctor, many lice are killed.
The Vice President survives the disaster and travels with Travis and a female Lice to the forbidden zone in hopes of finding a new home. The three make it to safety, only for the Vice President to betray Travis by shooting the female lice in the head.
He then corners Travis and shoots him in both his knees and tells him that he will rebuild their destroyed village. He mocks Travis' theories of a living world and shoots the ground, Clyde's head. Clyde feels them and in seconds reaches up and picks up the Vice President and tosses him to his death.
Appearance
The Vice President is a louse. He has gray, receding hair and burns on major portions of his body from the lice removal shampoo.
