This article is about the depressed robot. For the Martian, see Marvin the Martian.
Marvin is a robot made by the Sirius Cybernetics Corporation, and thanks to its marketing division, which according to The Hitchhiker's Guide to the Galaxy is "a bunch of mindless jerks who'll be the first against the wall when the revolution comes", he was shipped with a Genuine People Personalities prototype which happened to be a very depressed one.
He has tried his hand in the music industry with the not-so-classic hits "Marvin", "Metal Man", "Reasons to Be Miserable", "Marvin, I Love You", and "Marvin's Lullaby".
In short, Marvin is a very depressed robot.
