Benson

Benson is a gumball machine with pinkish-purple/red gumballs (that always seem to align in the shape of a beard) enclosed by a glass dome, sunken eyes and a large, straight nose that just about overlaps his mouth. While story boarder Benton Connor has noted that his gumballs may act as facial hair, this is easily disproven by his actual facial hair grown throughout the series. Despite having rather long arms and legs, Benson is relatively short compared to most other characters. It is also worth noting that his dispenser slot sits in a rather phallic position, and the latch being open seems to be the equivalent of him being naked. The turn switch on his chest is shaped like a heart symbol, hinting that's most likely where his heart is.

Benson's gumballs also change color depending on certain things Benson is feeling. The most common example of this is when he gets angry, in which they quickly turn a bright shade of red. The gumballs also turn a darker shade of pink (almost gray) when Benson is feeling incredibly sad. When becoming sick, as shown in "Sandwich of Death", his gumballs will turn green.

Benson appears as bald throughout almost the entirety of the main events of the series (with the exception of The Dome Experiment and the finale). Benson did previously have hair, which was a medium chestnut brown. It is revealed to have all fallen out in the episode Expert or Liar, after he was humiliated on the game show "Say That Word." Despite being bald, however, Benson is still able to grow facial hair rather quickly. It has been shown on numerous occasions that he will quickly grow a stubble if he goes even just a day without shaving, implying that he shaves at least once a day. In the finale, Benson is shown with long, grown out hair, which could imply that it was able to grow the entire time, but he voluntarily kept it shaved, which could be very possible given the situation of his facial hair. While, in The Dome Experiment, Benson does grow a full head of hair, given that its color is drastically different from what his hair normally looks like, it is likely that this was nothing more than a visual-aesthetic choice as a comedic reference to the Rambo film series, in which the main character has an identical hairstyle along with a red headband.

Benson is easily the most short-tempered character of all. His short temper is usually contributed by the lack of productivity by Mordecai and Rigby, as they always prefer to slack off and play video games rather than doing their jobs. Benson often threatens to fire Mordecai and Rigby if they don't finish their work or do a simple task such as buying tortillas or going to a Karaoke Bar. Whenever they destroy park property or slack off, Benson loses his temper, turning varying shades of red, and often ends up yelling at Mordecai and Rigby. Although this could be because he wants to push them to do better and to learn from their mistakes. Aside from his short fuse, Benson is usually calm and, in fact, is friendly and social, even with Mordecai and Rigby. Whenever Benson is in a good mood, he'll reward his employees with time off, usually in the form of nightly entertainment or dining out.
