Cliff Clewless is the incompetent chief of engineering aboard the space station R.U. Sirius. He is lazy, unworried and always wears a cap and sunglasses. Cliff never puts much effort into designing or building effective equipment. When asked to create a robot, for example, he created Bucky, which is merely a bucket on a coat rack. He hardly ever worries about things, which leads to frequent troubles like losing Earth's moon to the Saturnians in a blackjack game. Cliff has a cool and easy attitude and a high opinion of himself.
