Warden Helga Heel, full name Helga Hildius Heel, commands absolute authority over the prison planet Geo. She enforces her rule by declaring all inmates her personal property, compelling them into forced labor deep within the planet. Her physical traits include violet hair and brown eyes.

Helga's core motivations are acquiring and maintaining power, wealth, and sexual gratification. She exploits her position to coerce sex from prisoners, specifically targeting females. She frequently selects women such as Cara for personal sexual servitude. Helga also engages sexually with her subordinate, Zena, sometimes directing him to sleep with chosen female inmates while she watches.

She demonstrates strategic self-preservation, always maintaining an escape route to avoid accountability. This becomes essential when new prisoners, Guy and Raina, arrive investigating Dr. Vail. Vail's experiments transform inmates into flesh-hungry monsters, accelerating the planet's chaos under Helga's governance. During a confrontation, Helga undergoes a monstrous transformation herself and kills Cara. Wearing a white fur coat, she attempts to flee but fails to escape Geo's final collapse.

Her background is inextricably linked to the illegal empire she built on Geo, founded on slavery and systemic exploitation. The planet's deterioration reflects her escalating brutality and unchecked authority.
