Penelope Lang

Penelope Lang (Catherine Disher) is Betty's self-obsessed rival on Earth, who thinks of herself as the most popular girl at her school. Her favorite pasttime is ridiculing the other students, Betty and Noah in particular. She is rich, spoiled, and often uses her popularity or wealth to undermine Betty's social standing, a plan that inevitably goes wrong and violently backfires on Penelope every time. She is usually seen with two sidekicks named Megan and Sarah. She’s used to getting her own way — even if it means stepping all over other people. In fact, she enjoys getting her own way more if she has to step over other people to do so. In "Bracelet Yourself", she tampered with Betty's bracelet which is property of the Galactic Guardians and caused the Starcruiser to lose control. She also seems to not hate, but despise Betty enough to be violent, for in "Pre-Teen Queen of Outerspace", she attempts to kill Betty and her friends, though she thinks it is just a dream. Being Betty's rival, she also dislikes Noah just about as much as she dislikes Betty. Though she has come close to discovering the existence of the Galactic Guardians, having stolen and tampered with Betty's bracelet in "Bracelet Yourself" and read out of Betty's own "captain's log" in Power of the Pharaoh (causing people to think Betty is a science fiction author), Penelope quickly dismisses all of this. She doesn't believe any of the evidence is real, which is fortunate for Betty

In When the Cold Breeze Blows Away, she is the one who survived in during USRAC War that she and her friends appeared in during World War III

She was deceased by Alexia Ashford in fire execution after Alexia's soldiers captured her. She died in during Alexia's rules and allied with Nguyen Van Thieu.
