Heloise is the tritagonist of Jimmy Two-Shoes. She a super-intelligent and ultimately destructive 14-year-old (10-year-old in other countries; turns to 15 or 11 in season 2) girl. Her mad scientist's mind and penchant for chaos are hidden behind a weak facade of a diminutive sweetness that 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.
She is also shown to be pretty villainous on occasions.
She was voiced by Tabitha St. Germain. In the Japanese dub from the series, she was voiced by Yuka Takakura.
Heloise is an teenager who has brown hair with a ponytail and a scar on his forehead, she wears an red dress.
Heloise is shown to be cruel, short-tempered, sadistic, evil, power-hungry, psychopathic and overall violent in nature. She is often seen as an evil genius/mad scientist who enjoys spreading chaos wherever she goes.
She does have feelings, proven by her crush on Jimmy. In "Fused Together" she has a shrine dedicated to Jimmy in a small room hidden behind a cabinet which has been "found" by other characters. Her shrine appears again in "Pet Rocky" (Only this time it's behind the fireplace). She has a hair-trigger, violent temper. She has a crush on Jimmy but doesn't particularly care for Beezy, tolerating him (barely) mainly because of her fondness for Jimmy.
