Luna is a bright bubbly moon who is a parent/teacher-like figure to Andy, Carmen, and Leo. She is patient, caring, and can get a bit silly at times. She is a friend to everyone on Earth and is held in an almost celebrity-like esteem by many when she appears. Her biggest weakness is dancing, whenever she hears really happy music, she automatically starts dancing. This can often devolve into chaos as she has almost no control over herself once she begins.
