The Hitchhiker's Guide to the Galaxy Characters

The Hitchhiker's Guide to the Galaxy Character List

Arthur Dent

Arthur Dent is the main protagonist of The Hitchhiker’s Guide to the Galaxy. He is an average English man of about 30 years old. Arthur is not particularly clever or otherwise remarkable and often comes across as nervous or confused.

Ford Prefect

Ford Prefect is Arthur’s best friend. Although he blends into human society well, it is revealed that Ford is actually an alien of the Betlegeusian race sent to Earth to do research for a book titled The Hitchhikers Guide to the Galaxy. He became stranded on earth and couldn't hitch a ride until the vogons (an alien race) came to destroy earth. He accompanies Arthur on their adventures across the galaxy.

Zaphod Beeblebrox

Zaphod Beeblebrox is a Betelgeusian who formerly served as President of the Galaxy. He is incredibly clever and intelligent, but also has trouble reasoning and is irresponsible and seems to lack morals. He has two heads, three arms, and an awful taste in clothing. Although he is not a villain, Zaphod’s irresponsibility, stupidity, and other flaws seem to cause Arthur and Ford a lot of trouble when they arrive on his ship.


Trillian is a human woman from Earth who is initially presented as Arthur’s love interest, but who is soon approached by Zaphod Beeblebrox and easily convinced to fly away with him on his ship. She does, however, grow to despise Zaphod and becomes Arthur's love interest once again. She is very intelligent and approaches problems much more logically than Beeblebrox, or anyone else for that matter.


Marvin is a robot aboard Zaphod Beelzebrox’s ship who is depressed and extremely pessimistic. He is often annoyed by Eddie, the name given to the ship, due to its overly-cheery “personality.” Marvin has the brain the size of a planet but doesn't do much unless asked, in part because of his severe depression.


Slartibartfast is a Magrathean alien who helps to design planets. He won an award for designing the coast and fjords of Norway, and he also worked to create parts of Africa. He explains to Arthur the origin of Earth as well as why Earth was destroyed.
