Orc - he is a mythological beastie, borrowed from the Tolkein books, and the realm of Middle Earth. He's large, strong, mute and dumb, used as warrior by the bad guys in the series, they look like they are made of piles of rock.

The Orc at Thursdays, though, has been "tamed" with a radio collar and remote control, and is used for heavy lifting and other such tasks. He has been trained not to eat Lady (the resident dog at Thursday's, in real life she belongs to Lady's Human - or vice versa) or Rupert, who came to Thursday's as a little orange kitten, got accidentally covered in blue paint for a time, but has grown out of that. (He is completely virtual, like the bar itself.)
