Susan was hired as The Park manager by Mr. Maellard, because of Mordecai and Rigby's actions, but Benson was blamed for, these being prank calls worth up to $500, snacks disappearing from the snack bar, and holes in the walls. Susan was to help get the park back on track and fix the many errors that Benson made, even launching an indirect insult about how Benson managed the park. At first, Susan appeared to be nice and organized, but later, she started showing her true personality. She first fired Benson, after directly refusing to obey Susan's overworking demands and giving the consent to fire him, after becoming a slacker like Mordecai and Rigby. She then forced everyone else to work incredibly hard, and in the process, they begin transforming into clones of herself, albeit with their own faces. However, Benson stayed as his old self and helped free Mordecai, Rigby, and everyone else from Susan's influence by convincing them to slack off. This made Susan angry, so she went into the ground and returned as a giant. She tried to kill everyone with a building in her hands but Mr.Maellard came and stalled her so she dropped the building and picked up Mr. Maellard instead and was about to crush him until Leon drove Mr. Maellard's limo at Susan and smashed off both of the heels in her shoes. Without the heels on her shoes, Susan lost balance and fell into the fiery pit, killing her.
She wears a black suit-like jacket and a white turtleneck. She has blonde hair that is done in a bun, with red lipstick, and white earrings.
