Editing Marvin the Paranoid Android (section)

==Radio and TV series==
According to his autobiography read in the Secondary Phase of the radio series, Marvin was constructed, much against his own wishes, by the Sirius Cybernetics Corporation to prototype human personality artificial intelligence. In his own words:{{fact|date=December 2023}}

I didn't ask to be made: no one consulted me or considered my feelings in the matter. I don't think it even occurred to them that I might have feelings. After I was made, I was left in a dark room for six months... and me with this terrible pain in all the diodes down my left side. I called for succour in my loneliness, but did anyone come? Did they hell.<!-- it is "Did they hell"- for reference, see this audio clip: http://www.bolis.com/onyx/random/stuff/sounds/hhgttg/04.wav --> My first and only true friend was a small rat. One day it crawled into a cavity in my right ankle and died. I have a horrible feeling it's still there...|author=Douglas Adams|source=from Fit the Twelfth (radio series)}}

The cutaway illustration of Marvin made by [[Kevin Davies (director)|Kevin J. Davies]] for the "Depreciation Society" featured a "rat cavity".<ref>{{cite web| url=http://sotcaa.org/history/sotcaa2000/sotcaa2000_frame.html?/history/sotcaa2000/editnews/hhgttg.html | title=SOTCAA Records and Tapes | website=sotcaa.org | access-date=2017-03-27 }}</ref>

As the menial labourer on the ''Heart of Gold'' spaceship, he grew immensely resentful of the insistence of his new masters ([[Zaphod Beeblebrox]] and [[Trillian (character)|Trillian]]; later also [[Ford Prefect (character)|Ford Prefect]] and [[Arthur Dent]]) that he open doors, check airlocks and pick up pieces of paper. He reserved a particular contempt for the sentient doors, despising their blissful satisfaction with existence.{{fact|date=December 2023}}

<!--This section is about the radio and TV series in which Miliways was on Magrathea; it was only Frogstar B in the book.-->
When the ''Heart of Gold'' crew arrive on the ancient planet of Magrathea, they abandon Marvin on the surface. During an apparently suicidal confrontation with a pair of trigger-happy cops, the crew are teleported directly from Magrathea into the future to the [[Restaurant at the End of the Universe]] to find that, in fact, they have not travelled at all. The Restaurant was constructed on the ruins of the planet they had just left, and, while there, they find Marvin, who had been waiting patiently for their return for 576,000,003,579 years (he counted them). According to Marvin, "The first ten million years were the worst, and the second ten million years, they were the worst too. The third ten million I didn't enjoy at all. After that I went into a bit of a decline." Apparently, the best conversation he had was over 40 million years ago with a [[coffee]] machine.{{fact|date=December 2023}}

Deciding they had better leave, the crew make a desperate and futile attempt to engage Marvin's enthusiasm (he "hasn't got one") before he simply does what they really want and opens the door to the ship they want to steal. The ship turns out to be a Haggunenon battle cruiser, and the entire group, including Marvin, but excluding [[Ford Prefect (character)|Ford Prefect]] and [[Arthur Dent]], who escape, are eaten by its crew. Marvin's subsequent survival is never explained, but against all probability, he eventually finds himself on Ursa Minor Beta, just in time to rescue Zaphod from a robotic tank.{{fact|date=December 2023}}

A subsequent section of Marvin's biography occurs only in the Secondary Phase of the radio series. Marvin rejoins the crew on the ''Heart of Gold'', and using the improbability drive programmed by Zaphod Beeblebrox the Fourth, takes them to the ravaged planet Brontitall. Having landed in a giant floating marble copy of a plastic cup, the crew accidentally find themselves falling several miles through the air. The carbon-based members of the crew manage to stay alive by grabbing onto passing giant birds. Marvin has no such luck, and, upon impact with the ground, creates his own archaeological excavation site. Cruelly intact, he grudgingly saves the crew multiple times from the Foot Soldiers of the Dolmansaxlil Shoe Corporation. Marvin remains in ''Heart of Gold'' whilst Ford, Zaphod, Zarniwoop and Arthur bother the Ruler of the Universe, leaving when an enraged Arthur hijacks the ship.{{fact|date=December 2023}}

However, in the Tertiary Phase, Trillian claims this story is Zaphod's hallucination, especially as the reverse temporal engineering explanation has not entered the plot yet. However, of the stories of Zaphod's visit to the Frogstar, the Guide says "10% are 95% true, 14% are 65% true, 35% are only 5% true and the rest are told by Zaphod Beeblebrox", and listeners are presented with one "version" of that visit.{{fact|date=December 2023}}

In the television series, the black ship stolen at the Restaurant at the End of the Universe is actually the stunt ship of the [[Minor characters from The Hitchhiker's Guide to the Galaxy#Hotblack Desiato|Disaster Area]] rock band, and, having taken them back in time two million years before the present, is set on an irreversible course to collide with the sun of Kakrafoon. Forced to flee in the ship's barely functional teleport, the crew politely ask Marvin to stay behind and operate it. He does so and stoically awaits his fate "almost as good as death" in the heart of the blazing sun.{{fact|date=December 2023}}
