Duchess is a member of a group of young superheroes called the S-Force from the planet Sarus.
Duchess, along with the rest of the S-Force, protects the innocent of the galaxies from evil. She along with the rest of her teammates first suspected Coop to be a bad, she later learned that he wasn't evil, just a little dull-witted. Despite this they became good friends. Duchess pilots the Pink Panther Zorp, which resemble a large pink cat.
A flashback in "S-Force S.O.S.", due to her interactions with Coop, Duchess learned how to make loud burps, thanks to training with soda and Rock Pops.
- Duchess is a parody of Princess, a variation of Jun from Battle of the Planets (the first English adaptation of Gatchaman).
