This figure paper model is Ford Prefect (also called Ix), a fictional character in The Hitchhiker's Guide to the Galaxy, the papercraft created by BazookaJo, and it is 7.5'' tall. Ford Prefect is the only character other than the protagonist, Arthur Dent, to appear throughout the entire Hitchhiker's saga. His role as Arthur's friend - and rescuer, when the Earth is unexpectedly demolished to make way for a hyperspace bypass at the start of the story - is often expository, as Ford is an experienced galactic hitch-hiker and explains that he is actually an alien journalist, a field researcher for the titular Guide itself, and not an out-of-work actor from Guildford as he had hitherto claimed.
Ford is pragmatic to the point of fatalism, endlessly broad-minded - no doubt due to his vast experience of roughing it around the galaxy - and possessed of an off-key and often very black sense of humour. He is described as being able to smile in a way that would "send hitherto sane men scampering into the trees". In his role as guide to the universe for the often bewildered everyman Arthur Dent, he serves to link the disparate elements of the story together. As well as rescuing Arthur, he introduces him to the other major characters - such as Zaphod, Trillian and Marvin the Paranoid Android - and to numerous mind-boggling concepts, from 'teasers' (an explanation of UFO sightings on Earth) to the extraordinary usefulness of towels. Ford's other chief characteristic is his constant pursuit of alcoholic drinks and a good time (in contrast to Arthur's quest for a cup of tea). Adams said finding motivations for Ford's character in order to keep him engaged in the narrative became increasingly difficult as the series of novels progressed, because although his heart is in the right place and he is shown to be highly intelligent, resourceful and even brave, Ford is essentially a dilettante when it comes to causes such as the search for the question to the ultimate answer of life, the universe and everything.
Ford is approximately two hundred years old, as supported by the books. When, in the first novel, Zaphod steals the spaceship Heart of Gold, it is on his- two-hundredth birthday. It is later mentioned that Ford and Zaphod attended school together, even having some of the same classes, which would indicate that they are roughly the same age. [Source: wiki]
