She was originally a Homeworld Gem technician and a certified Kindergartener. After being stranded on Earth following the events of "Jail Break", she acted as a recurring antagonist until becoming more of an anti-hero and pseudo-antagonist by establishing a truce with the Crystal Gems in "When It Rains" to help them save the Earth from the Cluster. She officially became a member in "Message Received" after she defied her Homeworld superior, Yellow Diamond.
