Duchess is a recurring antagonist of Cartoon Network's Foster's Home for Imaginary Friends. She serves as the main antagonist in the pilot episode.

She is voiced by Grey DeLisle. 

Villainous Act

  • Duchess actually attempted to murder Bloo (along with Wilt, Eduardo and Coco) by releasing "Extremeosaurs" on him and the others.


Duchess has pale yellow skin, and wears makeup, a white fur coat, high heels, earrings, a necklace, and bracelets. Her whole body resembles that of a portrait by Picasso.


Duchess is a snobby, pompous, arrogant and self-centered imaginary friend. She's considered a "high-maintenance" friend, not wanting to do anything for herself, and is so lazy that she needs somebody to open her eyelids when she wakes up. She is shown to be bossy as she ordered the staff of the Home around so much, ensuring that they do stuff perfectly such as washing her "fine linen" separate from the other clothes.
