Jade was the last addition to the cast of Astroblast, making her first appearance in the second Astroblast movie, Astroblast in Paris: The Movie. She is very joyful and brave. She was introduced as Jet's new sister, after her mother, Chloe Mender, married Jet's father Robert. This marriage and the changes it brought to the Mender family were used in the series to teach the young viewers, by demonstration, about adapting to such drastic changes caused by remarriage. In Astroblast, the one-and-a-half year old Jade was portrayed as very brave and often stumbled into dangerous situations she was too naïve to recognize, often bringing her new brother, Jet Mender, along, which he didn't like very much. He described her as "another Halley" not too long upon her arrival. She is just as adventurous as Halley and cares for her friends. Unlike Halley, she often takes action first and thinks later. She laughs in the eye of danger and is always looking for an adventure. In Astroblast: All Grown Up!, she develops a strong relationship with Halley.
