Penny Robinson is one of the main characters in the Netflix series Lost in Space.
The middle child in the family. Penny is quick-witted and contrarian, but her sarcastic and tough exterior covers a romantic soul. If the Robinsons have a black sheep, she’d be it. She’s the most social person in her family, with the best sense of humor of any of them. Penny grew up the victim of middle-child-syndrome, caught between a superstar older sister who could do no wrong and a baby brother who everybody was afraid couldn't do anything right. She didn't want to leave her home on Earth, and struggles with the loss of everything and everyone she knew.
