A fully evolved, sentient, humanlike robot scientist, Dr. Widnar theorized carbon-based lifeforms could exist, but until the day she met the Planet Express crew, she never had any proof. She took them to the Museum of Natural Robo-History, where the Professor gave a speech. However, when he revealed that he invented the Nanobots in the first place, the Doctor felt dissapointed, and left the building. She probably went to another planet.
- The amazing, non-mechanical man, Homo farnsworth.
- Her name is an anagram of Darwin, a reference to Charles Darwin, a naturlist who proposed the theory of evolution.
- Bender seems to like her.
Dr. Widnar: I'm Dr. Widnar, a naturalist.
Bender: And I'm Bender, baby.
Dr. Widnar: Welcome, museum members... or, as I like to call you, future exhibits. [No one speaks. Some robot coughs.]
Dr. Widnar: I don't want to live on this planet anymore.
