Zaphod Beeblebrox IV is Zaphod Beeblebrox's (the former President of the Galaxy) deceased great-grandfather. He helps Zaphod, Ford, Arthur, Trillian, and Marvin escape the Vogons in The Restaurant at the End of the Universe by teleporting them to safety using his dead-person-powers. He is rather ill-tempered at times, and holds his great-grandson (who he calls "Zaphod the Nothingth") in contempt for being so irresponsible. It is he who explains Zaphod's original plans for finding the 'man running the universe.'
