Susan

Susan made her debut in Benson Be Gone. She was hired by Mr. Mallard to replace Benson as the park's manager, and at first, Susan appeared to be nice and organized, but then she started showing her true personality, where she first fired Benson when he refused to work ruthlessly after becoming a slacker like Mordecai and Rigby. She then forced everyone else to work really hard, and in the process, they begin transforming into clones of her. However, Benson returned to his old self and helps free Mordecai, Rigby, and everyone else from Susan's influence by convincing them to slack off. This enraged Susan so much, she went into the ground and returned as a giant. She tried to kill everyone with a building in her hands, picked up Mr. Mallard and was about to crush him until Leon drove Mr. Mallard's limo at Susan and smashed off one of the heels in her shoes, causing her to fall to the pit where she came out as a giant, burning and being wished to never return.
