She's a bank robber and master thief who hypocritically claims feminist arguments to justify her crimes despite not knowing even the simplest facts about the woman she claims to be honoring with her thefts. With shoddy reasoning, wrapped in some unfair truths, she convinces Blossom, Bubbles, and Buttercup to fight against men and boys so she can continue to rob banks. She steals only Susan B. Anthony coins since all other forms of money have men on them. At the end of the episode Equal Fights, she is promptly defeated and taken to jail after the sisters tell her who the suffragist Susan B. Anthony really was. She is a blonde and wears a white jumpsuit with multiple blue stripes with a periwinkle mask and headband.

- When she's wearing convict stripes at the end of Equal Fights, we find out that she has blue eyes and she complains that the horizontal stripes of the uniform make her look fat.
