Zaphod Beeblebrox
Zaphod is from a planet in the vicinity of Betelgeuse, and is a "semi-half-cousin" of Ford Prefect, with whom he "shares three of the same mothers". Because of "an accident with a contraceptive and a time machine", his direct ancestors from his father are also his direct descendants. He also has two heads and three arms and often 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. Zaphod is hedonistic and irresponsible, narcissistic almost to the point of solipsism, and often extremely insensitive to the feelings of those around him.
It can not be coincidence that this basically describes the actual current President of the Galaxy. When asked to comment about the similarities between himself and the character in the book, the President said that he could “neither confirm or deny” that he took part in any of the adventures in the books, but that “it was a fun ride”.
