Judith "Judy" Angela Jetson is the very beautiful 16-year-old daughter of George and Jane Jetson, who acts just like a normal teenage girl only with more futuristic tastes.
Despite Judy still keeping modern-day "teenage girl" likes and dislikes, such as seemingly never-ending conversations on the telephone and shopping for futuristic outfits, she does not live exactly like a modern teenager, obviously because of the time the show takes place, because she enjoys taking advantage of the many gadgets at her grasp because of the technology (like controllable zero-gravity switches made for accomplishing popular dance moves of the show's time or for other uses). She also gives a summary of how her day went including her problems to a floating robotic diary, appropriately named, "DiDi".Judy is also very fond of a futuristic rock singer named "Jet Screamer", whom George at first despised until Judy won a date with the heartthrob singer in a contest in which girls who wanted to win a date with Jet Screamer were to write songs, and the writer of the winning song would win the date. Judy won because George replaced her original song with her younger brother Elroy's secret code. George came along to try to stop the date but failed and wound up as the drummer for the song and soon took a liking for Jet Screamer and his music.
She is a teenage Caucasian female with platinum blonde hair which is tied up in a pretty ponytail held upward above her head. She wears a long red skirt with ruffles.
Despite her beauty, Judy is the typical teenage girl. She is obsessed with boys, rock stars, clothes and loves to hang out with her friends from Orbit High School.
Judy can usually be found goggling at posters and listening to the radio in her room, but she does make time to encourage her little brothers's inventions and help her mom out shopping.
