It was for the sake of this day that he had first decided to run for the Presidency, a decision which had sent waves of astonishment throughout the Imperial Galaxy - Zaphod Beeblebrox? President? Not the Zaphod Beeblebrox? Not the President? Many had seen it as a clinching proof that the whole of known creation had finally gone bananas.

Zaphod Beeblebrox is a "semi-half-cousin" of Ford Prefect.
He is hedonistic and irresponsible, narcissistic, and often extremely insensitive to the feelings of those around him. Zaphod invented the Pan Galactic Gargle Blaster. Zaphod wears unique clothing that contains a mixture of bright and contrasting colours to make him stand out and be the centre of attention wherever he goes. He was voted "Worst Dressed Sentient Being in the Known Universe" seven consecutive times. He's been described as "the best Bang since the Big One" by Eccentrica Gallumbits, and as "one hoopy frood" by others. He was briefly the President of the Galaxy and is the only man to have survived the Total Perspective Vortex (In the artificial galaxy created by Zarniwoop).
