Manobrain (Duck Dodgers)

Manobrain is a tentacled alien with a large brain and psychic abilities who used to be friends with I.Q. Hi. Their friendship ended in college when they blamed each other for the loss of a prototype weight-loss pill they invented. Monobrain became a criminal mastermind and resurfaced to steal the secret codes that were to be used in the event that the President of Outer Space accidentally locked himself in his walk-in closet. He hid the codes inside Duck Dodgers' brain and had to help I.Q. Hi, Cadet, and Duck Dodgers' egos recover it before the President ran out of air. While in Dodger's brain they realize that Duck Dodgers stole their weight loss pill.
I.Q. Hi and Manobrain ended up renewing their feud when the fresh breath pill they invented goes missing, again at the hands of Dodgers. Manobrain was voiced by Lewis Black.
