Moonstone is a soft-spoken, socially-incompetent psychic. She can be quite submissive as well, such as with Diary when she was in her alliance, but that may be due to the fact that she has a crush on her. Despite her appearance, she can still lose her cool at times, like when Headset repeated her rhyme in Chao Down. She got very angry, and this happens on occasion. Since Moonstone is a psychic, she possesses several psychic abilities, such as mind reading, telekinesis, and levitation.
