Once an entertainer on Homeworld, she was seduced by the idea of a Rebellion on Earth and has since lived as a guardian of The Factory Temple.
Moonstone has pale blue skin, cyan lips, and lavender-blue hair kept in pigtails. She has a long nose and plump lips, as well as big arms and wide hips. She wears a blue sleeveless top with a triangular ivory pattern, a skirt of the same palette with an inverted triangle. The skirt reaches the knee, which is the height of her boots. Her calves are separated from her thighs. Moonstone's gem is located on her right cheek.
