Aubrey Posen

Aubrey Posen is the secondary antagonist/anti-hero of Pitch Perfect.

Near the end, she and the girls have a heart to heart and she becomes full on hero from here on out.

However, she returns to antagonist/anti-hero status with the films sequel, after opening up a retreat.

She is portrayed by Anna Camp, who also portrays Sarah Newlin.
