Heloise is a super-intelligent and ultimately destructive 14-year-old (turns to 15 in season 2) girl in the cartoon, Jimmy Two Shoes. Her mad scientist mind and penchant for chaos is hidden behind a weak facade of a diminutive sweetness which almost everyone can see past. She is one of only two human characters and works for Lucius by creating weapons of mass destruction. In series she is one of if not the most feared person in all Miseryville. While to most people she is violent or indifferent she is kind and helpful to her crush, Jimmy Two Shoes.
