        Marvin, more fully known as Marvin the Paranoid Android, is an incredibly brilliant but overwhelmingly depressed
        robot manufactured by the Sirius Cybernetics Corporation and unwilling servant to the crew of the Heart of Gold.
      </p>
      <hr />
      <div className="content">
        <h4>Physical Appearance</h4>
        <p>
          In the novels, Marvin is described thusly: "...though it was beautifully constructed and polished it looked
          somehow as if the various parts of its more or less humanoid body didn't quite fit properly. In fact, they fit
          perfectly well, but something in its bearing suggested that they might have fitted better."
        </p>
        <p>
          On the radio show, there's no physical description of Marvin, though his voice is digitally altered to sound
          more robotic, and any scene that focuses on him is accompanied by sounds of mechanical clanking and hissing.
        </p>
        <p>
          In the TV series, Marvin is built in the style of a 1950's robot similar to Robbie the Robot from Forbidden
          Planet or Twiki from Buck Rogers. His body is blocky and angular, with a pair of clamp-claw hands, shuffling
          feet and a squarish head with a dour face.
        </p>
        <p>
          In the movie, Marvin is a short, stout robot built of smooth, white plastic. His arms are much longer than his
          legs, and his head is a massive sphere with only a pair of triangle eyes for a face. His large head and
          simian-like proportions give Marvin a perpetual slouch, adding to his melancholy personality. At the start of
          the film his eyes glow, but at the end he is shot but unharmed, leaving a hole in his head and dimming his
          eyes. This is probably the most depressing and unacceptable manifestation of Marvin ever conceived, and thus
          paradoxically the most accurate.
        </p>
      </div>
      <hr />
      <div className="content">
        <h4>Personality</h4>
        <p>
          Marvin the robot has a prototype version of the Genuine People Personality (GPP) software from SCC, allowing
          him sentience and the ability to feel emotions and develop a personality. He's also incredibly smart, having a
          "brain the size of a planet" capable of computing extremely complex mathematics, as well as solving difficult
          problems and operating high-tech devices.
        </p>
        <p>
          However, despite being so smart, Marvin is typically made to perform menial tasks and labour such as escorting
          people, opening doors, picking up pieces of paper, and other tasks well beneath his skills. Even extremely
          hard tasks, such as computing for the vast Krikkit robot army, are trivial for Marvin. All this leaves him
          extremely bored, frustrated, and overwhelmingly depressed. Because of this, all modern GPP-capable machines,
          such as Eddie the computer and the Heart of Gold's automatic doors, are programmed to be extremely cheerful
          and happy, much to Marvin's disgust.
        </p>
        <p>
          Marvin hates everyone and everything he comes into contact with, having no respect for anybody and will
          criticise and insult others at any opportunity, or otherwise rant and complain for hours on end about his own
          problems, such as the terrible pain he suffers in all the diodes down his left side. His contempt for everyone
          is often justified, as almost every person he comes across, even those who consider him a friend, (such as
          Arthur and Trillian, who treat him more kindly than Ford and Zaphod) treat Marvin as an expendable servant,
          even sending him to his death more than once (such as when Zaphod ordered Marvin to fight the gigantic,
          heavy-duty Frogstar Scout Robot Class D so he could escape). Being a robot, he still does what he's told (he
          won't enjoy it, nor will he let you forget it, but he'll do it anyway), though he'd much rather sulk in a
          corner by himself.
        </p>
        <p>
          Several times in the series Marvin ends up alone and isolated for extremely long periods of time, sometimes
          spanning millions of years, either by sheer bad luck (such as the explosion that propelled everyone but Marvin
          to Milliways in the far-off future) or because his unpleasantly depressing personality drives them away or, in
          more than one case, makes them commit suicide. In his spare time (which he has a lot of), Marvin will attempt
          to occupy himself by composing songs and writing poetry. Of course, none of them are particularly cheerful, or
          even that good.
