A living gumball machine. Benson is Mordecai and Rigby's hot-tempered boss. The two frequently infuriate him due to their constant slacking and mischief, and as such he has limited trust for them, even though it's his responsibility since their mistakes happen on his time. However, he loosened up a bit after "Benson Be Gone", having gained some degree of understanding for them. He is a responsible and hardworking employee, the exact opposite of Mordecai and Rigby. His head turns red whenever he's extremely angry (which happens very frequently).
