Judy Robinson is a main character of the 2004 unaired television pilot The Robinsons: Lost in Space. Judy is portrayed by Adrianne Palicki.
In this version, Judy was possibly the first or second child of John and Maureen Robinson. Judy is a teenager, and has a teenage brother named David, a ten-year-old brother named Will who happens to be a genius, and an infant sister named Penny. (Note: Both David and Judy Robinson appear to be about the same age. It is possible that they are fraternal twins. However, there is no way to prove this). This version of Judy was very outgoing. She had few friends due to her military father and was constantly moving as a child. As a teen, Judy grew quite headstrong and occasionally rebelled against her parents. Judy fell passionately in love with Major Don West, who she met at a going away party. Instead of the silver astronaut suit, these Robinsons wore a two piece white suit that was closable all the way to the collar.
