*Stacy was Samantha's college roommate and the main antagonist in "Evil Roommate".

When she first began her college career, Stacy struggled to keep up with the other students at Malibu University. Rather than pushing herself further, Stacy decided she'd rather get someone else do her homework and get easy A's. Stacy began her sophomore year in Malibu University when Samantha, Clover and Alexandra began their freshman year. Her new roommate was Samantha and she had already known about Samantha's intelligence and saw her as a new addition for A's on assignments. So, when Samantha finally arrived, Stacy greets her energetically which is rather unsettling for Samantha whereas Clover and Alexandra found her to be nice.

As it turns out, she was the mastermind of an evil plan to steal the knowledge of numerous Malibu University students. In order to do this she created a machine which can drain knowledge.

She is later arrested by WOOHP and all of her victims were freed.

She wanted to be a top student but instead of putting in effort, chose the easy route and kidnapped intelligent students to drain their knowledge for homework.

Stacy is quite intelligent as she built a machine that would siphon people's intelligence and onto her homework assignments. To put it simply, Stacy is lazy and likes the easy way out. She can act happy and friendly but is nosy and inappropriate (e.g. opened Samantha's moving boxes before officially meeting her). She showed her ugly side when Samantha answered a question (that was directed to Stacy) correctly as she absolutely despises people who are smarter than her. She yelled at Samantha and got everyone's sympathy vote by pulling the victim card for her much to the extreme discomfort of Samantha. When Stacy found her lost scrunchie on Clover, she aggressively yanked it off of her which hurt and didn't care that it did.*
