which stands for Small Computer System Interface. Scuzzy is last seen in "Firewall". The User The human operator of Mainframe is perceived by its denizens as a distant, impersonal, deity-like figure. Often destructive, it subjects the city to Game Cubes and assumes various avatars to do deadly battle with the unfortunates trapped within them. In layman's terms, the User is a computer owner that enjoys playing PC games, blissfully unaware of the havoc they are causing. Nonetheless, Mainframers dutifully petition the User to bestow upon them gifts such as increased memory and software upgrades, prayers which are sometimes answered despite the User's sadly limited means. Of all the characters depicted, only Fax Modem openly professed to deny the existence of the User, a position roundly regarded as wildly unorthodox and borderline insane. The User never appears on screen, although in the third-season finale its keystrokes could be heard as it entered the command to reboot the system. In the season one finale of The Guardian Code, the User is finally revealed to be an overweight, bearded man who still lives with his mother and plays games in her basement. Season one characters Cecil A video screen with a pair of arms, waiter at Dot's Diner before it was destroyed. Stereotypical French waiter complete with small moustache. He refers to himself as a "dedicated server", a play on his waiter job and Server (Computing). He greatly resembles the original Apple Macintosh, even his icon has rainbow stripes resembling the Macintosh logo. Although nearly the entire cast pronounces his name Cee-Cil, he has repeatedly asserted that it is actually pronounced Ceh-cil. (Unlike the rest of the cast, Dot pronounces it correctly.) Cecil was originally limited to moving along a rail within the Diner (in other words, he was nearly sessile); after the Diner's destruction, Cecil's rail arm was attached to a hoverboard, allowing him freedom of movement,The Cecil Hotel in Vancouver was fairly close to MainFrame Productions Studio, and the logo on Cecil's chest also closely resembles that club's logo. Al's Diner Al owns Al's Diner (also known as Al's Wait & Eat) on Level 31, and also serves as cook. According to his waiter, Al runs at 3 decahertz (30 Hz). Almost never seen, the only times he is explicitly shown on screen is when he is tied and completely covered up with rope in the episode "The Great Brain Robbery",
