Shelly is Stan's older sister. She's got huge headgear braces on her teeth, enjoys using the word "turds", and loves beating the crap out of Stan. Although she doesn't like her little brother, she sticks up for him when he gets into trouble.
She briefly had a musician boyfriend named Skylar and an online boyfriend named Amir. Neither relationship panned out.
