Mr. Litwak is the owner of Litwak's Arcade, where the film takes place. He doesn't know about anything that goes on in Game Central Station; however, Mr. Litwak is indirectly both a foe and friend to the video game characters. Because Mr. Litwak depends on a customer base for his livelihood, he must keep gamers, such as Moppet Girl, satisfied. Should customers complain of glitches and the games cannot be repaired, Mr. Litwak withdraws it from his arcade, leaving those game characters "unplugged," their version of homeless and unemployed. The same goes for games which have not generated a high level of customer support. The flip side is that should a game be both functional and popular, it stays at Litwak's Arcade, and thus the game characters are assured of being "plugged." Mr. Litwak is shown to be a "realist" element to the film; a man in the real world trying to own and operate his business.
Role in the film
In the film, he is the friendly owner and operator of Litwak's Arcade. When one of his customers tells him that Fix-It Felix, Jr. is busted, due to Ralph's quest for a medal, he takes a closer look at the console screen and noticed all the Nicelanders in a panic, before refunding the girl's money. The girl starts to worry and asks him what will happen to the game. He tells her that someone will have to take a look at the game tomorrow, but if it is not fixed, the game will be unplugged and soon places an "out of order" sign on the machine.
The next day, when he finds out that the game's working correctly, he's quite pleased as it means he won't have to unplug it at all.
In Felix's story of Turbo and King Candy's story of the fate of Sugar Rush, players (two boys and Moppet girl, respectively) call Mr. Litwak, who places "out of order" signs to the games gone wrong (RoadBlasters and TurboTime, respectively).
He is seen throughout the film dressed like a football referee. This is also the work uniform of game technicians at the franchise Dave & Buster's, who check to see that arcade cabinets are fully functional, as well as replenish games that dispense prize tickets when the supply is exhausted.
His appearance and dress also seems to be a reference to Walter Day, the founder of Twin Galaxies, an organization that records world record high scores on arcade games.
Litwak's first name was originally going to be "Larry."
