The Country Club Leader is the main antagonist of the Regular Show episode, "Country Club".
The Country Club Leader is first seen after pranking Mordecai and Rigby with a $100 bill tied to a string. After Mordecai attempts to dirty up the Country Club by using the Cart, the Country Club Leader steals the Golf Cart for, at first, an unknown reason.
Soon later, it was revealed that the Country Club Leader takes objects from other people (mainly The Park) and turns them into toilets using his Toilet Making Machine. Ironically, the Country Club Leader was then turned into a toliet himself and was shot off into space where he was still seen floating around.
At the beginning of the episode, the Country Club Leader appeared to be a stuck-up, ostentatious, wealthy, and rich person who loves to mess around with the less fortunate. However, his personality suddenly turned darker once he revealed that he not only intended to turn the golf cart into a toilet, but Mordecai and Rigby as well.
