Mr. Flibble.
Mr. Flibble is a hologramatical hand puppet penguin. He is fluffy and malevolent, and often "very cross". In the episode Quarantine, Arnold Rimmer wore Mr. Flibble on his hand and together they terrorised the rest of the crew. Rimmer had been infected by a hologramatical virus, the "Hex virus", which gave him mental powers, but also made him completely psychotic. Both Mr. Flibble and Rimmer were armed with the dreaded power of Hex vision. When they attack with this power, their eyes glow red, and then a deadly beam of energy was discharged from their eyes.
Mr. Flibble is now an interviewer on the Red Dwarf official website, aided by the right hand of website coordinator Andrew Ellard.

I loved that episode! "Red Dwarf" is one of, if not THE funniest, shows ever. The only other contenders are "Monk", "Father Ted", "Wings", and the first three seasons of "M*A*S*H".
