Though Gart is very arrogant and mean, he usually does seem to keep promises (as he did give the apartment back, and did give Robot money for his internal gyroscope in "The Prince of Scamtown"). Gart gave the building back as promised afterwards.
Robot fought back finally by challenging Gart to a contest (in which Gart picked Rock, Paper, Scissors), and won by inventing a device that literally summoned a piece of paper to cover Gart's rock fist. As landlord, he harassed and tormented Robot and Monster by turning off the heat, turning the heat up too much, and even giving Ogo the ability to host fire drills whenever he pleased (even very early in the morning or in the middle of the night). However, this ended badly when Gart bought the apartment building from Mr. In "Between Brothers," Monster invited Gart to his and Robot's apartment for dinner, in an attempt for the two Defaults to become friends.
He appears to be somewhat of a miser, as revealed in "The Prince of Scamtown" that he refused to loan Robot money because he needed it to "wipe his butt" but he does spend his money for the price of seeing his brother suffer. It is evident that Gart's employees dislike him (except for Monster), but they work for him because they need the money. The screen can be changed (as shown in the episode, "Blinking Light") to different views, even a happy, bright field with double rainbows in the sky. A wall screen behind the desk usually shows a black void with large flames burning. His desk can sink into the floor to make it shorter or climb higher towards the ceiling in order to appear more intimidating. His office is large and spacious, with pictures of relatives (though notably, Robot's picture does not appear) on the walls.
He also openly torments his employees (particularly Robot and Perry), and, in case of an injury (such as a severed limb), has a policy that prevents injured employees from going to the hospital during their work hours. As a boss, he's cruel and ruthless, having many rules against any sort of relaxation or comfort within the factory. According to Gart in the episode, "Between Brothers," Gart apparently was the favorite of the two Default children, while Robot was the black sheep of the family due to his inventions not working properly.ĭespite feeling superior to his brother, Gart still hired Robot to work in their father's factory as part of quality control, along with Robot's best friend, Monster. By his tenth birthday, Gart inherited the Blinking Light Factory from his father, and has since become successful in nearly everything he's done. Unlike his younger brother, Gart has four-fingered hands, which he has taken advantage of by constantly beating Robot in games of Rock, Paper, Scissors, as Robot is only capable of using scissors due to his pincher claws.
