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. According to Marvin the Paranoid Android, they are also the worst marksmen in the galaxy. They follow orders as they were told to and will not allow exceptions.
