Main character appearance summary

Elizabeth Miervaldis "Liz" Lemon (Tina Fey), the series' protagonist, is head writer of TGS with Tracy Jordan. Jack Donaghy calls her a "New York third-wave feminist, college-educated, single-and-pretending-to-be-happy-about-it, over-scheduled, undersexed, you buy any magazine that says 'healthy body image' on the cover and every two years you take up knitting for... a week." Lemon is a Star Wars fan and is portrayed as a "geek." She also lacks certain social skills and is a stress eater, particularly ingesting junk food. She is generally shown to have liberal political views. Despite her high standards in men, personified in her imaginary perfect husband, Astronaut Mike Dexter, Lemon has had some "really terrible boyfriends," but eventually finds happiness with Criss Chross, with whom she adopts two children.
