Vogon

The Vogons are a fictional alien race from the planet Vogsphere in The Hitchhiker's Guide to the Galaxy—initially a BBC Radio series by Douglas Adams—who are responsible for the destruction of the Earth, in order to facilitate an intergalactic highway construction project for a hyperspace express route. Vogons are slug-like but vaguely humanoid, are bulkier than humans, and have green skin. Vogons are described as “one of the most unpleasant races in the galaxy—not actually evil, but bad-tempered, bureaucratic, officious and callous", and having "as much sex appeal as a road accident" as well as being the authors of "the third worst poetry in the universe". They are employed as the galactic government's bureaucrats.

Guide Description:

Here is what to do if you want to get a lift from a Vogon: forget it. They are one of the most unpleasant races in the Galaxy. Not actually evil, but bad-tempered, bureaucratic, officious and callous. They wouldn't even lift a finger to save their own grandmothers from the Ravenous Bugblatter Beast of Traal without orders – signed in triplicate, sent in, sent back, queried, lost, found, subjected to public inquiry, lost again, and finally buried in soft peat for three months and recycled as firelighters. The best way to get a drink out of a Vogon is to stick your finger down his throat, and the best way to irritate him is to feed his grandmother to the Ravenous Bugblatter Beast of Traal. On no account should you allow a Vogon to read poetry at you.

Vogons are roughly human-sized, although much bulkier, with green or grey skin. Their noses are above their eyebrows, which are either ginger (in the television series) or white (in the film). The film's commentary states that the idea behind the high flat noses was that they evolved both the noses and the severe bureaucracy from being repeatedly whacked by the paddle creatures under the sand on Vogsphere whenever they had an independent thought (in the film, the Vogon bureaucracy is centred on Vogsphere). In the radio series it is said that "Their highly domed nose rises above their small piggy forehead".

Garth Jennings deliberately based his conception of the Vogons on the work of cartoonist James Gillray (1757–1815). "His creations were so grotesque...when we looked at them, we realised they were the Vogons".
